Description

(54) DEVICE FOR COATS OF SILKWARE COCONS

J

The invention relates to sericulture and can be used at the primary processing of cocoons.

Conveyor structures are known for drying and milling 5 silkworm cocoons, consisting of conveyors, loading and unloading conveyors, and a heater with an inlet fan Til.

The disadvantages of these devices are the complexity of the design and relatively low productivity.

At present, a conveyor coconut dryer is used for drying and wrapping, in which the cocoons are pickled with humid air, the temperature of which decreases as they dry out 2j.

This device for filling the furnaces consists of a fire heater drying cabinet, a circulation fan, a water supply system, and a fuel supply system. In the drying cabinet there are three working conveyors. From one of them, the cocoons are poured onto a portable conveyor with a device for packaging dried cocoons. The air is heated in a fire heater and moistened with steam there. Subzero-30

Temperature and humidity at a given level is automated.

This coconut dryer has drawbacks such as high intensity and complexity of construction due to the presence of conveyors. In addition, the uneven distribution of the coolant and the humidifier inside the chamber, as well as high energy intensity (43 kW / h) reduce the performance of the coconut dryer.

The purpose of the invention is to simplify the design and increase productivity.

The goal is achieved by the fact that the loading chamber of the device is made in the form of a series of coaxially joined replaceable cylindrical sections having a through cylindrical channel located along the axis of each section, the walls of the channel and sections being perforated; Each section is exposed to at least two hoops spaced from the outer surface at a distance sufficient to pass between them and the surface of the hot air sections.

FIG. 1 - installation, general view of FIG. 2 shows section A-A in FIG. 1 of FIG. 3 - boot camera. The device contains an evacuated housing 1, which is connected on one side with a caliper (not shown), and on the other side it is equipped with a cover 2 connected with carriage 3 and an electromechanical actuator 4, the leading rollers of which operate on guide rails 5. On the trolley 3, moving along the guide rails 5, a loading chamber 6 is installed, which is a cylindrical section having a through channel, the walls of which are made of perforated material. From the air distributor 7 connected to the heater, equipped with a valve 8, hot air flows into the housing 1. Air ducts 9 serve for exhausting exhaust air. The device works as follows. . To activate the drive 4, the cover 2 opens and the cart 3 moves forward. At the same time, the air supply is preliminarily blocked (heat carrier into the evacuated body 1, when the valve 8 is brought into a vertical position. A loading chamber 6 filled with cocoons is installed on the cart 3, the cover 2 of the housing is closed closing the formed coaxially connected sections of the loading chamber through a cylindrical channel, which on the other hand. fits tightly to the air distributor 7. When the valve 8 is horizontal, the air vent heat exchanger 7, the passage through the cylindrical through channel penetrates through the perforated stack of loading chambers bis simultaneous drying dries cocoons. Exhaust air is sucked through the air ducts 9 into the heater for further use.On unloading, the finished raw material of the Hom 8, installed in a vertical position, overlaps the entry of hot air into the housing 1, the lid 2 opens and the carriage 3 extends. Then the cycle is repeated. The device allows to reduce energy consumption, fuel consumption. It is simpler in construction. The quality of the cocoons is enhanced by supplying the heat-transfer fluid to the raw materials. Claim 1. A device for silkworm cocoon wrapping, comprising an evacuated hull fitted with one side of the lid, on the other side communicating with a radiator, a trolley moving inside the hull along guide rails, and a loading chamber for cocoons characterized in that, in order to simplify the design and increase productivity, the loading chamber for cocoons is made in the form of a series of co-coaxially docked interchangeable cylindrical sections having a through cylindrical channel parallel to each oh section, and the walls of the channel and sections are perforated. 2. A device according to claim 1, characterized in that each section is surrounded by at least two hoops that are bent from the external surface at a distance sufficient to pass between them and the external surface of the hot air sections.
