Abstract
The utility model relates to the technical field of filter switching devices, particularly to a double-switching filtering device which comprises filters, a device inlet, a device outlet, and a pressure switch, wherein the device inlet is connected in parallel with the inlets of a first filter and a second filter through pipelines; the normally-opened pressure switch is arranged on the first filter inlet; a pressure probing element of the normally-opened pressure switch is arranged inside the first filter; the outlets of the first filter and the second filter are connected with the device outlet through pipelines respectively; a switching valve used for switching between the first filter and the second filter is arranged on the device inlet. According to the utility model, the two filters can be quickly switched through the pressure switch, so that the double-switching filtering device can be widely applied to the switching of various filters.
Description
[technical field]
The utility model relates to the switching device for filter technical field, specifically a kind of pair of switch filtering device.
[background technology]
In order to remove soluble impurity, obtain cleaner intermediate or product, need to use filter operation, and in chemical plant in order to realize in batches, the mechanical filter operation, need to use filter,
Filter is indispensable a kind of device on the pumped (conveying) medium pipeline, usually is arranged on the entrance point of pressure-reducing valve, relief valve, Valve for keeping constant water level or miscellaneous equipment, is used for eliminating the impurity in medium, with the normal use of protection valve and equipment.After fluid enters the filter cylinder that is equipped with the certain specification filter screen, its impurity is blocked, and clean filtrate is discharged by filter outlet, when needs clean, as long as dismountable filter cylinder is taken out, after processing, reloads and gets final product, and therefore, working service is very convenient.
In the prior art, a kind of hand as disclosed as domestic patent CN 102485311A is from twin-tub switch filtering device, comprise tank body, valve control system, blowback system, material stock recovery system, the valve control system that its principle is two tank bodies utilizing base to be provided with, the tank body upper inner is provided with and be positioned at the blowback system between the bilateral tank wall, realization, still can the quantity-produced function when rinsing operation.But the two filter vats in this device are separate structure, cause this filter volume huge, be not suitable in the operating process of hand work.
[summary of the invention]
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, and a kind of pair of switch filtering device is provided.
For achieving the above object, design a kind of pair of switch filtering device, comprise filter, the device import, the device outlet, pressure switch, it is characterized in that described device import is by the import of pipeline the first filter in parallel and the second filter, described the first filter inlet is provided with pressure switch open in usual, the pressure detecting element of described pressure switch open in usual is arranged in the first filter, the outlet of described the first filter and the second filter is connected with the device outlet by pipeline respectively, described device import is provided with the transfer valve switched between switching the first filter and the second filter.
Said structure also has following concrete optimizing structure:
Described filter is well strainer, cylindrical shell and the filter screen be placed in staving, consists of.
Described pressure switch is provided with pressure indicator.
The utility model can be switched fast by the pressure quick closing valve between two filters, can extensively be suitable for the switching with various filters.
[accompanying drawing explanation]
The structural representation that Fig. 1 is embodiment 1;
1. device import 2. device outlet 3. first filter inlet 4. second filter inlet 5. transfer valve 6. pressure switch 7. cylindrical shell 8. filter screen 9. pressure indicator 10. first filter outlet 11. second filter outlets in figure
[specific embodiment]
For making the purpose of this utility model, principle and product configurations more cheer and bright, now be further elaborated in conjunction with the drawings and the specific embodiments, believe for a person skilled in the art and can realize.
Embodiment
Comprise well strainer, the device import, the device outlet, pressure switch, wherein well strainer is comprised of cylindrical shell and the filter screen be placed in staving, pressure switch is provided with pressure indicator, described device import is by the import of pipeline the first well strainer in parallel and the second well strainer, described the first well strainer import is provided with pressure switch open in usual, the pressure detecting element of described pressure switch open in usual is arranged in the first well strainer, the outlet of described the first well strainer and the second well strainer is connected with the device outlet by pipeline respectively, described device import is provided with the transfer valve switched between switching the first well strainer and the second well strainer.
During use, the fluid that contains impurity enters from the device import, through the first well strainer, filter, be expelled to the device outlet from filter outlet, along with continuing of filtration time, accumulation of foreign matter gradually on filter screen in well strainer, pressure in filter increases gradually, the pressure of pressure switch can be set as required, when pressure sensor detects pressure in filter and reaches the pressure of setting, pressure switch is closed, and the pressure indicator on pressure sensor passes out corresponding information, just can carry out by transfer valve the switching of filter.
After switching, can pull down being cleaned of filter screen of the first filter, switch back again the first filter after cleaning and get final product.
Claims (3)
1. a two switch filtering device, comprise filter, the device import, the device outlet, pressure switch, it is characterized in that described device import is by the import of pipeline the first filter in parallel and the second filter, described the first filter inlet is provided with pressure switch open in usual, the pressure detecting element of described pressure switch open in usual is arranged in the first filter, the outlet of described the first filter and the second filter is connected with the device outlet by pipeline respectively, described device import is provided with the transfer valve switched between switching the first filter and the second filter.
