[0002] Donkey-hide gelatin is a traditional blood-replenishing medicine with the effects of replenishing blood, nourishing yin, and moisturizing dryness.

[0003] The production process of donkey-hide gelatin is to first soak and wash the raw material - dry donkey hair, remove the dirt on the donkey skin, then melt it under high pressure, and then add auxiliary materials such as rice wine to boil it into glue. The amount of sewage discharged during the soaking and washing process accounts for about one-third of the total sewage. The main pollutants in the water are insoluble substances such as mud, donkey hair, and donkey skin fragments. The sewage discharged during the donkey skin dissolution and boiling glue process mainly contains dissolved or gelatinous organic pollutants such as protein. At present, after adding purification agents, sewage treatment pools mostly use submersible sewage pumps to treat the purified wastewater. Since the submersible sewage pump works in water for a long time, the sealing requirements of the submersible pump are relatively high. However, in the current prior art, the cover and casing of the submersible pump are only sealed by a single sealing gasket, and the sealing effect is not good, so that there is a risk of water entering the casing. In view of this, the present utility model is specially proposed. Summary of the invention

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the utility model clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. The following embodiments are used to illustrate the utility model but are not used to limit the scope of the utility model. Example 1

[0022] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 A submersible sewage pump for treating wastewater from donkey-hide gelatin production comprises a submersible sewage pump body 1, the submersible sewage pump body 1 comprises a casing 101 and a cover 102 detachably connected to the casing 101, and further comprises: a sealing component connected to the cover 102 and fitted with the inner wall of the casing 101; a wrapping airbag 307 arranged around the inner side wall of the cover 102, wherein a sealing groove 308 corresponding to the wrapping airbag 307 is provided on the outer wall of the casing 101; a plug-in block 301 connected to the cover 102, wherein a slide groove 302 is provided on the plug-in block 301, and a sealing plug 304 is slidably connected in the slide groove 302; an elastic reset member is arranged in the slide groove 302 and used for resetting the sealing plug 304; a pipe 1 305 fixedly connected to the slide groove 302; a pipe 2 306, one end of which is fixedly connected to the slide groove 302, and the other end of which is fixedly connected to the inner cavity of the wrapping airbag 307.

[0023] The sealing component includes a fastening ring 2 and a sealing ring 201 . The fastening ring 2 is fixedly connected to the machine cover 102 . The sealing ring 201 is fixedly installed on the outer wall of the fastening ring 2 and fits with the inner wall of the housing 101 .

[0024] The elastic return member includes a spring 303 , one end of the spring 303 is fixedly connected to the sealing plug 304 , and the other end of the spring 303 is fixedly connected to the inner wall of the slide groove 302 .

[0025] It also includes an activated carbon filter, which is arranged in the air inlet end of the pipeline 1 305.

[0026] When assembling the cover 102 and the housing 101, the cover 102 is first covered on the housing 101 to achieve a closed seal on the housing 101. At the same time, when the cover 102 is covered on the housing 101, the sealing ring 201 is squeezed by the fastening ring 2 inserted in the housing 101, so that the sealing ring 201 is tightly fitted with the inner wall of the housing 101, thereby increasing the sealing performance of the connection between the cover 102 and the housing 101. Then, the sealing plug 304 is pressed to make the pressed sealing plug 304 slide into the depth of the slide groove 302 and compress the spring 303. Then, the sealing plug 304 is released, and the compressed spring 303 generates a thrust to push the sealing plug 304 to slide out of the slide groove 302, so that the sealing plug 304 is pressed into the slide groove 302. 02, the sealing plug 304 reciprocatingly slides to form a piston movement. At this time, when the sealing plug 304 slides out of the slide groove 302, the external gas is sucked into the slide groove 302 through the pipe 1 305, and then when the sealing plug 304 slides deep into the slide groove 302, the gas is squeezed by the sealing plug 304 and transported into the wrapped airbag 307 through the pipe 2 306. Both the pipe 1 305 and the pipe 2 306 are provided with a one-way valve, and then the air is transported to the wrapped airbag 307 to increase the pressure, so that the wrapped airbag 307 with gradually increased internal air pressure expands and fits tightly with the sealing groove 308, further improving the sealing performance of the connection between the cover 102 and the housing 101, and effectively preventing sewage from penetrating into the housing 101 and causing damage to the electronic devices inside the housing 101;

[0027] At the same time, the external gas contacts the activated carbon filter when passing through the pipeline 305, which is not shown in the figure. Since the activated carbon has a developed void structure and rich microporous organization inside, these microporous organizations have a strong adsorption force field. When the gas contacts the activated carbon, the strong adsorption force field of the activated carbon micropores can adsorb the particulate matter in the air into the micropores, thereby filtering and purifying the gas. The filtered and purified gas is then transported into the chute 302 through the pipeline 305 for temporary storage. Example 2

[0028] Reference Figure 1 , Figure 3 and Figure 6 A submersible sewage pump for treating wastewater from donkey-hide gelatin production is basically the same as Example 1. Furthermore, a connecting ring 3 is fixedly connected to the machine cover 102, a fixing ring 4 is fixedly connected to the machine casing 101, a plug-in groove 401 corresponding to the plug-in block 301 is opened on the fixing ring 4, a clamping block 402 is fixedly connected to the sealing plug 304, the clamping block 402 is clamped on the surface of the fixing ring 4, and the plug-in block 301 is fixedly connected to the connecting ring 3.

[0029] It also includes a pipeline three 309, which is fixedly connected to the machine cover 102 and communicated with the inner cavity of the wrapped airbag 307. The pipeline three 309 is provided with a valve switch.

[0030] When the machine cover 102 is closed on the housing 101, the plug-in block 301 moves with the machine cover 102 and is plugged into the plug-in slot 401. At this time, the clamping block 402 is squeezed by the fixing ring 4 to push the sealing plug 304 to slide into the slide slot 302 and compress the spring 303 until the clamping block 402 is completely retracted into the slide slot 302. When the machine cover 102 is fitted with the housing 101, the slide slot 302 on the plug-in block 301 moves out of the plug-in slot 401, and the compressed spring 303 generates a thrust, which pushes the sealing plug 304 to drive the clamping block 402 to slide out of the slide slot 302 and be clamped on the surface of the lower side of the fixing ring 4. Therefore, the assembly of the machine cover 102 and the housing 101 can be completed conveniently without the help of professional tools.

[0031] When it is necessary to disassemble the cover 102 and the casing 101, first open the valve switch on the pipe three 309 to allow the gas to be discharged from the wrapped airbag 307 through the pipe three 309, and then press the clamping block 402. After being pressed, the clamping block 402 pushes the sealing plug 304 to slide into the slide groove 302 and compresses the spring 303 until the clamping block 402 is completely retracted into the slide groove 302, thereby releasing the limit fixation of the cover 102, and then move the cover 102 to the side away from the casing 101 to complete the disassembly of the cover 102 and the casing 101. Therefore, when the electronic components inside the casing 101 are damaged, the cover 102 and the casing 101 can be disassembled to facilitate the repair of the electronic components inside the casing 101.

[0032] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention.
