DESCRIPTION

Title of the Invention

TABLET DISPENSING DEVICE FOR WASTEWATER MANAGEMENT SYSTEMS

Technical Field

[0001] The object of the invention is a tablet dispensing device for wastewater management systems, which is characterized in that it includes a connection in the form of a cap nut for mounting the device on a sewer revision, and a controller and motor controller to control the position and frequency of actuation of the tablet pusher, connected to each other, with the motor controller also connected to the motor.

Background Art

[0002] Various types of tablet dispensing devices are known to be used in systems for wastewater management, such as those shown in the Chinese utility model CN215048992U, which describes a dispensing device for a slow-release solid substance release used in wastewater treatment equipment, and the device includes a container, a pushing and shifting device, a limiting element for the shifted part, a wedge-shaped material guiding groove, a material transfer device material, a metering transfer track, a feeding system, a moisture-resistant screen, and a floating support. However, the solution presented uses a pre-tank from which the tablets are transported to the track. This is realized with using a rotary feeder containing tablet slots. In addition, solution is technically advanced, using several stages to transport the tablets, which increases the probability of failure of the entire process and forces the use of more mechanisms, which increases costs. The description does not also provided information about mounting the device to a sewer revision, which may make the device more difficult to access, clean and install. It does not describe also the use of a controller and controller to manage the process of transporting the tablets, which may make it difficult to automate the process. [0003] In contrast, US patent application US5206168A describes aa mechanically driven device that transports a biological tablet underground, into an underground denitrification chamber. However, the solution presented uses gravity to move tablets into the denitrification chamber by releasing a spring-loaded locking pin. There is probability that this element will jam, which can cause uncontrolled placement in the denitrification chamber of more tablets than assumed, exposing the user to financial loss. In addition, the description does not provided information about mounting the device to a sewer revision, which may hinder accessibility to the device, its cleaning and installation. Also not described is the use of a controller and controller to manage the tablet transport process, which may make it difficult to automate the process.

[0004] In contrast, Chinese utility model CN204281461 U describes a device for wastewater treatment containing an L-shaped directional channel. However, in the solution presented, there is no information about the use of the device's connection for dispensing tablets to the sewer revision. This may cause difficulties with accessibility to the device, its cleaning and installation. Also not described is the the use of a controller and controller to manage the tablet transport process, which may make it difficult to automate the process.

Summary of Invention

Technical Problem

[0005] The purpose of the invention was to develop such a tablet dispensing device for wastewater management systems, which is characterized by the fact that it includes a connection in the form of a cap nut for mounting the device on a sewer revision, and a controller and motor driver to control the position and frequency of actuation of the pusher travel, connected to each other, with the controller also connected to the motor. The device in the form according to the invention eliminates the aforementioned problems of accessibility to the device, its cleaning and assembly, and the automation of the tablet dispensing process.

Solution to Problem

[0006] The essence of the invention is a tablet dispensing device for a wastewater management systems, which includes a device housing to which a tablet container is attached for tablets, which are pushed out through an outlet opening through a tablet pusher mounted on a linear guide, driven by a motor. The device is characterized by the fact that it includes a connection in the form of a cap nut for mounting the device on a revision sewer, and a controller and motor controller for controlling the position and frequency of actuation of the tablet pusher, connected to each other, with the motor controller being also connected to the motor.

[0007] It is good if the cap nut contains anti-slip tabs arranged around its periphery to facilitate assembly.

[0008] It is advantageous if the outlet opening has dimensions corresponding to those of the tablet pusher.

[0009] It is preferable if the device includes limit switches connected to the controller.

[0010] It is advantageous if the device includes a wireless communication module for controlling the process by external devices.

[0011] It is favorable if the tablet container has a cross-section complementary to that of the tablets, being situated one on top of the other.

[0012] It is advantageous if the device contains a flap with a spring, covering the outlet opening, preventing the entry of odor from the sewer revision.

Advantageous Effects of Invention

[0013] An advantageous effect of the tablet dispensing device for sewage management systems is the ability to mount the device to the sewer revision, as well as control the parameters of the tablet dosing process through the use of a controllers. Placing tablets in wastewater management system, such as in a domestic wastewater treatment plant, is an essential process to accelerate the decomposition of organic waste, treating wastewater more efficiently, reducing unpleasant odors generated in the wastewater treatment process, and reducing sludge, which in turn can reduce the frequency of the need to empty the treatment plant. In addition, the use of spring-loaded flap that covers the outlet opening, prevents odor from entering from the sewer revision, while allowing it to be swung open under the pressure of a tablet moved by a tablet pusher.

Description of Embodiments

[0015] In the implementation example, the tablet dispensing device for wastewater management systems, it includes a device housing 1 made of PVC plastic, to which is attached the tablet container 2 also made of PVC plastic. The housing 1 is bolted together with a screw connection 1 a so that it is possible to access its interior, the components of the device. The device also contains a connection in the form of a cup nut 3 made of PVC plastic, which contains spaced around its perimeter anti-slip tabs 3a to facilitate installation. The device housing 1 on the side of the cap nut 3 includes an outlet opening 1 b. Inside the device housing 1 is a motor 4 with a motor shaft 4a connected to the power source by a power cable 4b. To motor 4 a motor controller 5 is connected and a controller 6 is connected to the motor controller 5, via cables 7. The device also includes two limit switches 8 located in the housing connected to the controller 6 by cables 7. To the drive shaft 4a of the motor 4 transmission belt 9 is attached. The device also contains a linear guide 10, on which a tablet pusher 11 is mounted. To the sliding element 11 a of the tablet pusher 11 the transmission belt 9 is attached, which drives the tablet pusher 11 along the linear guide 10. The ejector element 11 b of the tablet pusher 11 moves the tablet 12 located in the tablet container 2 toward the outlet opening 1 b, through which the tablet 12 is pushed out into the sewer revision. The outlet opening 1 b has dimensions corresponding to those of the of tablet pusher 11 , and tablet container 2 has a crosssection complementary to that of tablet 12, which are situated one on top of the other. Motor controller 5 and controller 6 are designed to control the position and frequency of actuation of the tablet pusher 11. Controller 6 receives information from the limit switches 8, which inform about the position of the tablet pusher 11 , and based on this information, sends signals to motor controller 5, which then controls the motor 4. The limit switches 8 are positioned so that the tablet pusher 11 has a start position, in which tablets 12 are not dispensed, and an end position - when the tablet 12 is pushed out. The limit switch 8a is responsible for setting the start position engages upon contact with pusher 11 , while limit switch 8b is responsible for setting the end position.

[0016] In possible example of implementation, the device additionally includes a flap 14 with a spring 14a, attached to the device housing 1 by a hinge 14b, and the flap 14 covers the outlet opening 1 b, which prevents odor from entering from the sewer revision 13. The use of spring 14a allows the flap 14 to be tilted under the pressure of the tablet 12 moved by the tablet pusher 11 , and then returning the flap 14 to the sealing position, which occurs as the tablet pusher 11 is moved to the starting position. The use of a rubber gasket in contact with flap 14 makes it possible to eliminate the possibility of releasing odor from the sewer revision 13. The device can also include a wireless communication module for controlling of the process by external devices, such as e.g. a smartphone, by connecting to the controller 6. The user of the tablet dispensing device for wastewater management systems can, through the use of a wireless connectivity module, remotely disable the dosing of tablets 12, e.g. while away, and also change the dosing frequency. It is also possible to get a reminder that the tablet container 2 for needs to be refilled. A futureproof solution is also the possibility to purchase tablets 12 via an app connected to the device or automatically make such a purchase when the stock of tablets 12 is exhausted in tablet container 2.
