Description

Technical Field

[0001] This utility model relates to the technical field of silkworm rearing equipment. More specifically, this utility model relates to a silkworm egg processing device. Background Technology

[0002] Guangxi Zhuang Autonomous Region (hereinafter referred to as Guangxi) has a climate characterized by abundant sunshine and heat, long summers and short winters, and simultaneous rainfall and heat, making it highly suitable for mulberry cultivation and silkworm rearing. While the sericulture industry is developing rapidly, silkworm diseases are also at a high incidence rate, becoming one of the biggest threats to sericulture production, especially several major diseases including microsporidia, viral diseases, bacterial diseases, and fungal diseases. Nosema bombycis (Nb) is an obligate intracellular parasite of eukaryotic organisms and the pathogen of microsporidia parasitizing silkworm cells. Microsporidia can cause huge economic losses to the sericulture industry and is the sole target for quarantine of finished silkworm eggs, constraining the stable development of sericulture production. Many sericulture scientists have successively used methods such as hot water bathing, high-temperature soaking, or high-temperature dry steam treatment to treat silkworm eggs at specific stages to disinfect microsporidia within the silkworm embryo and prevent the transmission of microsporidia in the embryo. There is an urgent need in sericulture production for new technologies to control silkworm microsporidia through egg treatment to ensure safe silkworm breeding.

[0003] Therefore, silkworm eggs need to be treated with acid immersion and high-temperature steam to kill microsporidia. Current technologies often use acid immersion tanks to treat silkworm eggs, with heating elements installed inside to achieve simultaneous acid immersion and high-temperature treatment. To improve the uniformity of acid heating within the tank, workers usually need to manually stir the acid solution with a stirring rod. Since the heated acid solution produces acid fumes, these fumes evaporate from the open top of the tank during stirring, causing potential harm to workers. Furthermore, manual stirring is time-consuming and labor-intensive. Therefore, this technology is authorized under CN1. Utility model 07047490B proposes a uniform temperature and environmentally friendly silkworm egg soaking tank, which includes a main body filled with acid solution, an soaking frame containing silkworm eggs placed inside the main body, multiple heating belts set on the inner side wall of the main body to heat the acid solution, and stirring blades that are rotated on the side walls and bottom of the soaking tank to locally agitate the acid solution near the side wall of the main body. Although the above-mentioned patented technology solves the problem of high temperature acid gas volatilization affecting the health of workers, it has the drawback of not being able to agitate the acid solution in the middle, resulting in uneven heating of the acid solution and affecting the soaking efficiency of silkworm eggs.

[0031] like Figure 1 As shown, this utility model provides a silkworm egg processing device, which includes:

[0032] The shell is a cubic structure with a hollow interior and a sealed top; the interior of the shell is provided with an acid storage chamber 11 and an acid soaking chamber 12, the acid storage chamber 11 is provided with a heating mechanism and a first stirring mechanism; the bottom of the acid soaking chamber 12 is connected to the interior of the acid storage chamber 11 through a return pipe 21;

[0033] The liquid pump 2 has its inlet connected to the inside of the acid storage chamber 11 and its outlet connected to the inside of the acid immersion chamber 12. The inlet of the liquid pump 2 is connected to the inside of the acid storage chamber 11 through a first liquid guide pipe 22, and its outlet is connected to the acid immersion chamber 12 through a second liquid guide pipe 23. One end of the first liquid guide pipe 22 is connected to the inlet of the liquid pump 2, and the other end extends through the top surface of the acid storage chamber 11 into the acid storage chamber 11 and is located in the upper part of the acid storage chamber 11. One end of the second liquid guide pipe 23 is connected to the outlet of the liquid pump 2, and the other end is connected to a liquid guide port provided on the upper side wall of the acid immersion chamber 12.

[0034] A pickling frame 3 is located inside the pickling chamber 12, and silkworm eggs to be treated are placed inside the pickling frame 3.

[0035] In the above technical solution, this utility model provides a silkworm egg treatment device, which is used to treat silkworm eggs with acid and high-temperature steam to kill silkworm microsporidia. The silkworm egg treatment device includes a shell, which is provided with an acid storage chamber 11 and an acid soaking chamber 12. The acid storage chamber 11 is used to store acid solution. A heating mechanism and a first stirring mechanism are provided in the acid storage chamber 11. The acid solution is heated to the required temperature in the acid storage chamber 11. The stirring mechanism in the acid storage chamber 11 provides large stirring amplitude without interference from other equipment. The first stirring mechanism improves the uniformity and efficiency of acid solution heating. The heated acid solution is introduced into the acid soaking chamber 12. At the same time, a liquid pump 2 and a return pipe 21 are provided. The acid in the acid storage chamber 11 and the acid soaking chamber 12 is circulated to maintain the temperature of the acid in the acid soaking chamber 12. Preferably, the existing technology can be used to lay the heat insulation layer on the side wall, top surface and bottom surface of the acid soaking chamber 12 to reduce heat loss and further maintain the temperature of the acid in the acid soaking chamber 12. The acid soaking frame 3 can adopt the structure of the existing acid soaking frame 3, which is a cubic frame shape with multiple partition layers inside. Each partition layer includes partition blocks symmetrically arranged on both sides. The silkworm egg paper with the eggs laid by the mother moth (silkworm eggs) attached is placed on the partition layer, with one silkworm egg paper placed in each partition layer. Then, the acid soaking frame 3 with the silkworm eggs is placed into the acid soaking chamber 12 for acid soaking and heating treatment.

[0036] The silkworm egg processing device provided by this utility model not only provides a closed acid soaking space to prevent acid gas from evaporating and affecting the health of workers, but also improves the acid soaking efficiency of silkworm eggs by heating the acid solution in the acid storage chamber 11 to ensure the temperature of the acid solution used for soaking.

[0037] In another technical solution, the silkworm seed processing device includes a first stirring mechanism comprising a first stirring shaft 41 vertically disposed in the acid storage chamber 11 and a plurality of first stirring rods 42 spaced apart on the first stirring shaft 41, each first stirring rod 42 being made of a heat-conducting material.

[0038] The heating mechanism includes a plurality of first heating rods and a plurality of second heating rods embedded in the side wall of the acid storage chamber 11, with a second heating rod disposed inside each first stirring rod 42.

[0039] The above technical solution discloses the specific structure of the first stirring mechanism and the heating mechanism. Specifically, the first stirring mechanism includes a first stirring shaft 41 vertically positioned in the middle of the acid storage chamber 11, with multiple first stirring rods 42 spaced apart on it. These rods heat the acid solution in the storage chamber 11 while simultaneously agitating it significantly. Multiple first heating rods are embedded in the inner wall of the acid storage chamber 11, and a second heating rod is installed within each first stirring rod 42. The multiple first and second heating rods improve the heating efficiency of the acid solution. Combined with the rotation of the first stirring shaft 41, this greatly enhances the uniformity of heating the acid solution, heating it to a preset temperature (the temperature required for acid leaching). Both the first and second heating rods are made of Teflon-clad stainless steel, and the shell is preferably made of nylon.

[0040] In another technical solution, the silkworm egg treatment device includes a filter screen 31 and a guide plate 32 installed sequentially from top to bottom inside the acid soaking chamber 12, with the acid soaking frame 3 located above the filter screen 31. The guide plate 32 is inclined and has a return hole at its lower end that communicates with the return pipe 21. The filter screen 31, with a mesh size smaller than that of the sidewall mesh of the acid soaking frame 3, filters the returned acid solution, preventing impurities generated during the acid soaking process from entering the acid storage chamber 11. The inclined guide plate 32 promotes the return of the acid solution in the acid soaking chamber 12 to the acid storage chamber 11.

[0041] In another technical solution, the silkworm egg treatment device has an opening at the top of the acid soaking chamber 12, which is covered by a cover plate 14; the size of the opening is larger than the size of the acid soaking frame 3; the top of the acid soaking frame 3 is connected to the cover plate 14.

[0042] A telescopic mechanism 5 is vertically provided on one side of the housing, and its top (free telescopic end) is connected to the top of the cover plate 14 via an L-shaped connecting rod. The telescopic mechanism 5 can be a hydraulic or pneumatic telescopic rod.

[0043] In the above technical solution, an opening is provided at the top of the pickling chamber 12 for placing the pickling frame 3 downwards or lifting it upwards. The opening is provided with a cover plate 14 that can be opened and closed. The cover plate 14 can seal the opening. The size of the opening is larger than the size of the pickling frame 3, ensuring that the pickling frame 3 can be placed into the pickling chamber 12 through the opening and also lifted upwards from the pickling chamber 12. Furthermore, a vertical telescopic mechanism 5 is provided. The free end of the telescopic mechanism 5 is connected to the top of the cover plate 14 through an L-shaped connecting rod. The free end of the vertical side of the connecting rod is connected to the free end of the telescopic mechanism 5, and the free end of the horizontal side of the connecting rod is connected to the top of the cover plate 14. The vertical extension and retraction of the telescopic mechanism 5 causes the cover plate 14 to move up and down, thereby causing the pickling frame 3 to move up and down. There is no need for manual lifting of the pickling frame 3 to place it downwards or lift it upwards, reducing manpower consumption and avoiding hand corrosion from acid gas when hands are inserted into the pickling chamber 12.

[0044] In another technical solution, the silkworm seed treatment device has a first threaded rod 61 coaxially provided at the top of the acid soaking frame 3, and a connecting cylinder 66 rotatably provided at the bottom; a first threaded sleeve 62 is rotatably sleeved on the upper part of the first threaded rod 61, and the first threaded sleeve 62 is detachably connected to the middle part of the bottom surface of the cover plate 14.

[0045] The bottom of the pickling chamber 12 is vertically rotatably provided with a second threaded sleeve 63, and the upper part of the sleeve is threadedly rotatably provided with a second threaded rod 64. The second threaded sleeve 63 is coaxially arranged with the pickling frame 3. The lower end of the second threaded sleeve 63 is rotatably connected to the bottom surface of the pickling chamber 12, and the upper end is vertically upward and sequentially seals and rotates through the guide plate 32 and the filter screen 31. The lower thread of the second threaded rod 64 is rotatably inserted into the upper part of the second threaded sleeve 63, and the upper end is detachably connected to the connecting cylinder 66. The upper part of the second threaded rod 64 is slidably connected to the side wall of the pickling chamber 12 in the vertical direction through multiple horizontally arranged crossbars 65.

[0046] In the above technical solution, the present invention provides a first threaded rod 61 coaxially arranged at the top of the pickling frame 3. A first threaded sleeve 62 is rotatably fitted onto the upper part of the first threaded rod 61. The first threaded sleeve 62 is detachably connected to the center of the bottom surface of the cover plate 14. This can be achieved using existing technologies, such as a compression-type snap-fit ​​connection with a locking buckle or other detachable connection methods. A connecting cylinder 66 is rotatably arranged at the bottom of the pickling frame 3. The connecting cylinder 66 is detachably connected to the second threaded rod 64 (the specific connection method is the same as the detachable connection method between the first threaded sleeve 62 and the cover plate 14). The lower end of the second threaded rod 64 is coaxially inserted into the second threaded sleeve 63. The second threaded rod 64 and the second threaded sleeve 63 are rotatably connected by threads. The upper part of the second threaded rod 64 is connected by multiple horizontally arranged... The crossbar 65 is slidably connected to the side wall of the acid soaking chamber 12 in the vertical direction, that is, the second threaded rod 64 can only move up and down in the vertical direction. The lower end of the second threaded sleeve 63 is sealed and rotated through the guide plate 32 and the filter screen 31, and is rotatably connected to the bottom surface of the acid soaking chamber 12. The second threaded sleeve rotates around its own axis, driving the second threaded rod 64 to move vertically. The up and down movement of the second threaded rod 64 drives the rotating drum and the acid soaking frame 3 to move up and down. Because the second threaded rod 64 on the upper part of the acid soaking frame 3 is threadedly rotated to the first threaded sleeve 62, the acid soaking frame 3 moves up and down while rotating in a circular motion, thereby driving the silkworm eggs to rotate in the acid solution and improving the acid soaking efficiency. Preferably, the second threaded rod 64 reciprocates in both forward and reverse directions, thereby driving the acid soaking frame 3 to reciprocate upward and downward movements.

[0047] In another technical solution, the silkworm seed processing device further includes a motor 7, which is located in the placement cavity 13 at the bottom of the housing. The lower end of the first stirring shaft 41 rotates downwards through the bottom surface of the acid storage cavity 11 and extends into the placement cavity 13. The output shaft of the motor 7 is coaxially connected to the first stirring shaft 41.

[0048] The lower end of the second threaded sleeve 63 rotates downwards and seals through the bottom surface of the acid immersion chamber 12 and extends into the placement chamber 13. The second threaded sleeve 63 is connected to the output shaft of the motor 7 via a belt 71.

[0049] The above technical solution involves installing a motor 7 within the placement cavity 13 as the drive source for the first stirring shaft 41. The output shaft of the motor 7 is connected to the second threaded sleeve 63 via a belt 71. Preferably, the motor 7 is a reciprocating servo motor capable of forward and reverse rotation. Starting the motor 7 drives the first stirring shaft 41 to rotate, which in turn drives multiple first stirring rods 42 to agitate the acid in the acid storage cavity 11. Simultaneously, under the transmission action of the belt 71, the second threaded sleeve 63 rotates, further driving the second threaded rod 64 to move vertically up and down, pushing the connecting cylinder 66 and the acid-soaking frame 3 to rotate vertically and move up and down within the acid-soaking cavity 12. At the same time, multiple second stirring rods 83 also rotate. Using only one motor 7 to drive the first stirring shaft 41 and the acid-soaking frame 3 simultaneously reduces the number of power source devices and lowers equipment costs.

[0050] In another technical solution, the silkworm seed treatment device further includes multiple second stirring mechanisms, which are located inside the acid soaking chamber 12 and surround the outer periphery of the acid soaking frame 3. Each crossbar 65 is provided with a corresponding second stirring mechanism. Each second stirring mechanism includes a third threaded sleeve 81 vertically fixed on the corresponding crossbar 65, a second stirring shaft 82 with its lower end coaxially threaded and rotatably inserted into the upper part of the third threaded sleeve 81, and multiple second stirring rods 83 spaced apart on the second stirring shaft 82. The upper end of each second stirring shaft 82 is rotatably connected to the top surface of the acid soaking chamber 12.

[0051] A second stirring mechanism is further provided on each crossbar 65 to agitate the acid solution around the periphery of the pickling frame 3, thereby further improving the pickling efficiency. Specifically, each second stirring mechanism includes a third threaded sleeve 81 vertically fixed on the corresponding crossbar 65. A second stirring shaft 82 is rotatably inserted into the inner thread of each third threaded sleeve 81 (an external thread adapted to the inner thread of the third threaded sleeve 81 is provided on the lower circumferential side of the second stirring shaft 82, so that the second stirring shaft 82 and the third threaded sleeve 81 are rotatably connected). The upper end of the second stirring shaft 82 is rotatably connected to the inner wall of the top surface of the pickling chamber 12. Multiple second stirring rods 83 are spaced apart on each second stirring shaft 82. The third threaded sleeve 81 moves vertically along with the crossbar 65, driving the second stirring shaft 82 to rotate around its own axis, thereby driving the multiple second stirring rods 83 to rotate.

[0052] In another technical solution, the silkworm egg treatment device further includes an acid gas treatment mechanism, which includes an acid gas treatment box 9 located on the other side of the shell and an acid gas treatment pipe 91 connected to the top of the acid storage chamber and the acid soaking chamber and the acid gas treatment box 9; an alkali inlet is provided on one side of the acid gas treatment box 9. By setting up the acid gas treatment mechanism, the acid gas generated inside the acid storage chamber 11 and the acid soaking chamber 12 can be recovered. The acid gas enters the acid gas treatment box 9 through the acid gas treatment pipe 91 and neutralizes with the alkali solution, thus achieving the treatment of the acid gas.
