Description

Technical Field

[0001] The utility model belongs to the technical field of donkey-hide gelatin production equipment, and specifically relates to a foam removing device for donkey-hide gelatin production. Background Art

[0002] During the production of donkey-hide gelatin, foam removal is required. The purpose of foam removal is to further remove fine impurities in the glue solution, further degrade collagen into glands, peptides, polypeptides, amino acids, etc., and distribute them in a certain molecular weight distribution state.

[0003] The operation process of foam removal is to place the preliminarily concentrated glue solution in a concentration pot so that the glue solution maintains a certain steam pressure in the concentration pot, and slowly evaporate. When the floating foam impurities on the surface of the glue solution gather in the center of the pot, the foam is removed. Repeat this operation until the yellow fine foam appears on the surface of the glue solution, and then transfer the glue solution to the glue discharging pot.

[0004] Currently, in the process of donkey-hide gelatin production, foam is removed by a foam removing machine. For example, patent CN206587423U discloses a foam removing machine for donkey-hide gelatin production, which includes a box body. A foam removing groove is opened at the top of the box body, and a boiling groove is opened inside the box body and below the foam removing groove. A motor box is fixedly installed on the top of the box body and on the left side of the opening of the foam removing groove. A motor is fixedly installed inside the motor box, and the output shaft of the motor passes through the motor box and is fixedly connected to one side of a winding wheel. By setting the motor and through the cooperation of the winding wheel, fixed pulley, lifting plate and lifting block, when the winding wheel rotates, the rope will lift the lifting plate through the fixed pulley. When the lifting plate is lifted, the filter holes on the filter plate will allow the glue solution to flow through, while impurities cannot pass through and thus stay above the filter plate, so as to quickly remove impurities.

[0005] The above patent still has the following defects. Due to the lack of a mechanism for vibrating the filter plate, after the filter plate completes the impurity removal of the glue solution, when the glue solution is taken out of the box body, there is likely to be glue solution remaining on the filter plate, resulting in waste of the glue solution. This glue solution has gone through several processes and can become donkey-hide gelatin lumps as long as it gels. It is really a pity to waste it at this time. Therefore, in view of this, the present utility model is specifically proposed. Summary of the Invention

[0021] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the following will clearly and completely describe the technical solutions in the embodiments in conjunction with the accompanying drawings in the embodiments of the present utility model. The following embodiments are used to illustrate the present utility model but are not used to limit the scope of the present utility model. Embodiment 1

[0022] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , a defoaming device for donkey-hide gelatin production, including an electric heating kettle 1, and further including: a cover plate 101 detachably connected to the electric heating kettle 1; a connecting seat 301, which is vertically connected in the electric heating kettle 1. Among them, a guide rod 302 is fixedly connected to the connecting seat 301, a filter plate 304 is arranged in the electric heating kettle 1, the filter plate 304 is slidably connected to the guide rod 302, a limit block is fixedly connected to the guide rod 302, a spring 303 is sleeved on the guide rod 302, one end of the spring 303 is fixedly connected to the limit block, and the other end is fixedly connected to the filter plate 304; a rotating shaft 4, which is rotatably connected to the cover plate 101. Among them, a cam 401 is fixedly connected to the rotating shaft 4, a motor 402 is fixedly installed on the cover plate 101, a first bevel gear 403 is fixedly connected to the output end of the motor 402, a second bevel gear 404 is fixedly connected to the rotating shaft 4, and the second bevel gear 404 is meshed with the first bevel gear 403.

[0023] A cylinder 3 is fixedly installed on the cover plate 101, and the connecting seat 301 is fixedly connected to the output end of the cylinder 3.

[0024] During use, turn on the electric heating kettle 1 to heat the glue liquid in the electric heating kettle 1. When the glue liquid boils, the impurities in the glue liquid form complexes with a relatively small specific gravity and suspend on the liquid surface, gathering from the edge of the kettle towards the center, thereby achieving the effect of removing impurities in the donkey-hide gelatin. Then, start the cylinder 3. The cylinder 3 drives the connecting seat 301 to drive the filter plate 304 to move upward. When the filter plate 304 moves upward, the glue liquid will pass through the filter holes on the filter plate 304, while the impurities cannot pass through the filter holes of the filter plate 304 and are blocked above the filter plate 304, thus achieving the filtration and impurity removal of the glue liquid and improving the purity of the glue liquid. When the filter plate 304 moves to the upper end of the electric heating kettle 1, start the motor 402. The motor 402 drives the rotating shaft 4 to rotate through the meshing connection of the first bevel gear 403 and the second bevel gear 404. The rotating shaft 4 drives the cam 401 to rotate. When the cam 401 abuts against the filter plate 304, the filter plate 304 will move downward along the guide rod 302 under the push of the cam 401 and compress the spring 303. Then, when the cam 401 separates from the filter plate 304, the compressed spring 303 generates a thrust to push the filter plate 304 to move upward along the guide rod 302 to reset. Subsequently, repeatedly repeat the above operation for driving the filter plate 304 to move up and down reciprocally along the guide rod 302 to correct, so that the reciprocally moving filter plate 304 generates vibrations when hitting the connecting seat 301, thereby shaking off the glue liquid remaining on the filter plate 304. Therefore, when taking out the glue liquid from the electric heating kettle 1, the waste of the glue liquid is reduced. Example 2

[0025] Refer to Figure 1 、 Figure 2 A defoaming device for donkey-hide gelatin production is basically the same as that in Example 1. Furthermore, a support ring 2 is fixedly connected to the cover plate 101. A sealing ring 201 is arranged on the outer side wall of the support ring 2, and the sealing ring 201 is fitted with the inner wall of the electric heating kettle 1. By inserting the support ring 2 into the electric heating kettle 1 to squeeze the sealing ring 201 to fit with the inner wall of the electric heating kettle 1, it increases the sealing performance at the connection between the cover plate 101 and the electric heating kettle 1, thereby reducing the heat loss inside the electric heating kettle 1 and improving the boiling rate of the glue liquid heated by the electric heating kettle 1. Example 3

[0026] Refer to Figure 1 、 Figure 2, A defoaming device for donkey-hide gelatin production, which is basically the same as that in Embodiment 1. Further, it further includes a pressure relief pipe 202, and the pressure relief pipe 202 is fixedly communicated with the electric heating kettle 1. A pressure relief valve is provided on the pressure relief pipe 202. Since the pressure inside the electric heating kettle 1 gradually increases when the electric heating kettle 1 continuously heats the glue liquid, when the air pressure inside the electric heating kettle 1 is greater than the pressure relief value set by the pressure relief valve on the pressure relief pipe 202, the pressure relief valve automatically opens to relieve pressure, thereby keeping the pressure inside the electric heating kettle 1 constant and avoiding potential safety hazards caused by excessive pressure inside the electric heating kettle 1. Embodiment 4

[0027] Refer to Figure 1 , A defoaming device for donkey-hide gelatin production, which is basically the same as that in Embodiment 1. Further, it further includes a discharge pipe 103, and the discharge pipe 103 is fixedly communicated with the bottom of the electric heating kettle 1. A solenoid valve is provided on the discharge pipe 103. When it is necessary to take out the glue liquid filtered from impurities in the electric heating kettle 1, first open the solenoid valve on the discharge pipe 103, so that the glue liquid can be discharged from the electric heating kettle 1 through the discharge pipe 103. Embodiment 5

[0028] Refer to Figure 1 , A defoaming device for donkey-hide gelatin production, which is basically the same as that in Embodiment 1. Further, the cover plate 101 is detachably connected to the electric heating kettle 1 through a plurality of fixing bolts 102. By setting the cover plate 101 to be detachable, the filter plate 304 can be taken out of the electric heating kettle 1 by removing the cover plate 101, thus facilitating the cleaning of the filter plate 304.
