Circulating cocoon cooking machine

Abstract

The invention discloses a circulating cocoon cooking machine, which comprises a frame, a shell, a cocoon feeding part, a low-temperature part, a cooking part, a regulating part and an outlet part. A set of soup surface sprinkling device is arranged in front of the regulating part with a distance of 400-500 mm from a clapboard of a cooking room; the sprinkling device comprises a tap water switch, a solenoid valve, a temperature controller, a temperature control probe, a sprinkling pipe and pipe fitting, and the assembly sequence of all the members is as follows: the front end of the solenoid valve is connected with the tap water switch and the back end of the solenoid valve is connected with the sprinkling pipe; a coil of the solenoid valve is connected with the control output of the temperature controller and the temperature control probe is connected with a signal input end of the temperature controller; when the temperature is higher than a design temperature, the solenoid valve is automatically opened; when the temperature is lower than the design temperature, the solenoid valve is automatically closed; the surface of the sprinkling pipe is provided with two rows of holes, wherein one row of the holes are vertical to the soup surface and the other row of the holes are inclined to form an angle of 30-45 DEG in the direction which is opposite to the forward motion direction of a cocoon cage. According to the circulating cocoon cooking machine disclosed by the invention, the reelability percentage can be improved and rushing upon cocoons per 10000m can be reduced by about 2%; meanwhile, the yield and the quality of the cocoons are improved, the raw cocoon consumption is reduced, and the energy consumption is saved.

Description

technical field [0001] The invention relates to a cocoon cooking equipment for reeling silk, in particular to a circulating cocoon cooking machine. Background technique [0002] Cocoon cooking is an essential pre-process in the silk reeling industry. At present, there are three main types of cocoon cooking equipment: circular cocoon cooking machine, D211 disc cocoon cooking machine, and vacuum infiltration cocoon cooking machine. [0003] Circulating cocoon cooking machine is the most commonly used model in China at present. It has the advantages of simple structure, low cost, flexible process adjustment, relatively stable quality of cocoon cooking and convenient maintenance. However, with the widespread use of automatic silk reeling machines and the gradual improvement in performance, the cocoons of automatic silk reeling machines must be reeled, and the outer layer of boiled cocoons should not be overcooked. Due to the high speed of automatic silk reeling machines, high th...

Problems solved by technology

However, with the continuous improvement of the performance of the new silk reeling machine, while enterprises are pursuing high efficiency and high quality, this cocoon cooking process cannot meet the requirements of production. The outer layer of the cocoon is cooked; when reeling, there are many types of sliver, which increases the number of sliver failures, and the cleaning does not meet the customer's requirements, etc.

[0006] In addition, in the circulating cocoon cooking machine and the vacuum osmotic cocoon cooking machine, in order to supply water to maintain water balance, adjust the concentration of cocoon cooking soup to remove floating matter, and adjust the temperature of the section, the low-temperature water absorption section, middle water section, Water sprinkling pipes are installed around the static cooking section and the exit protection section. Although these four water sprinkling pipes have played a certain role and solved some problems, there is still a considerable gap with the requirements of the latter section of silk reeling.
