Description

Technical Field

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

[0002] Ejiao production wastewater refers to the wastewater generated in the production process of Ejiao, such as cleaning, extraction, purification and other production links, which will produce relatively high concentrations of industrial wastewater. This kind of wastewater has obvious characteristics: ① High organic content. The wastewater contains a large amount of organic matter, such as plant roots, fine particles and colloids, which makes the organic content of the wastewater high; ② High chroma, which is mainly due to the formation of colloids and soluble substances in the wastewater; ③ The suspended matter has a relatively light specific gravity. The suspended matter in the wastewater has a relatively light specific gravity, which makes it difficult for these substances to precipitate, increasing the difficulty of wastewater treatment.

[0003] Coagulation and sedimentation are widely used in wastewater from donkey-hide gelatin production, mainly as a pretreatment or post-treatment process for biological treatment. Coagulation and sedimentation can effectively remove suspended solids and colloidal substances in wastewater from donkey-hide gelatin production, creating better conditions for subsequent treatment steps. The coagulation and sedimentation treatment process is divided into: ① Adding coagulants to improve the coagulation and sedimentation effect, it is necessary to adjust the pH value to the optimal range. After adding the coagulant, the coagulant and wastewater are fully mixed by stirring to increase the contact opportunity between the coagulant and the suspended solids in the wastewater, thereby accelerating the coagulation effect; ② Stirring and mixing, after adding the coagulant, the coagulant and wastewater are fully mixed by stirring to increase the contact opportunity between the coagulant and the suspended solids in the wastewater, thereby accelerating the coagulation effect. Pollutants such as suspended solids, colloids and dissolved substances in the wastewater are condensed into larger particles and precipitated to the bottom under the action of gravity; ③ Solid-liquid separation, using physical methods to separate the solids and water after coagulation and sedimentation.

[0004] The existing sewage coagulation and sedimentation treatment device needs to be manually stirred and mixed when adding coagulant for purification, which cannot make the agent and sewage fully react, affecting the purification effect. In addition, the purified sewage will produce foam and sediment, which need to be manually processed separately, which is time-consuming and labor-intensive, and the treatment effect is not good. In view of this, the present utility model is specially proposed. Summary of the invention

[0005] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a device for treating wastewater from donkey-hide gelatin production which can overcome the above problems or at least partially solve the above problems.

[0006] In order to solve the above technical problems, the basic concept of the technical solution adopted by the utility model is: a device for treating wastewater from donkey-hide gelatin production, comprising a treatment pool, wherein discharge ports are symmetrically arranged at the upper ends of both sides of the treatment pool, collecting boxes are arranged on both sides of the treatment pool, a filter plate is arranged at the lower end inside the treatment pool, a lifting component for lifting the filter plate is arranged on the treatment pool, a scraper is arranged in the treatment pool, the scraper is flush with the discharge port, a moving component for moving the scraper is arranged on the treatment pool, mixing plates are symmetrically arranged in the treatment pool, electric telescopic rods are symmetrically arranged on the treatment pool, the telescopic ends of the electric telescopic rods are fixedly connected to adjacent mixing plates, and a drain pipe is arranged at the bottom of the treatment pool.

[0007] Furthermore, the lifting assembly includes a second motor, which is symmetrically arranged on the processing pool. A slide groove is symmetrically arranged in the processing pool. A second screw rod is rotatably connected in the slide groove. The second screw rod is fixedly connected to the output end of the second motor. A second moving block is threadedly connected to the second screw rod, and the second moving block is fixedly connected to the scraper.

[0008] Furthermore, the moving component includes a first motor, which is symmetrically arranged on one side of the treatment tank.

The first screw rod is fixedly connected to the output end of the first motor, and a first moving block is threadedly connected to the first screw rod, and the first moving block is fixedly connected to the filter plate.

[0009] In order to facilitate the removal of waste from the collection box for processing, further, a rotating plate is hingedly connected to the collection box.

[0010] In order to reduce the wear on the scraper, further, the lower end surface of the scraper is configured to be smooth.

[0011] In order to facilitate the waste to enter the collection box for collection better, further, the lower end of the discharge port is inclined.

[0012] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: compared with the existing wastewater treatment device for donkey-hide gelatin production, the utility model uses a scraper and a filter plate to automatically scrape off the sediment and foam and collect them in the collection box, and uses a mixing plate to automatically and fully mix the sewage and the coagulant, thereby effectively improving the treatment effect.

DETAILED DESCRIPTION

[0020] 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

[0021] Reference Figure 1-Figure 4 A device for treating wastewater from donkey-hide gelatin production, comprising a treatment pool 1, discharge ports are symmetrically arranged at the upper ends of both sides of the treatment pool 1, collecting boxes 2 are arranged at both sides of the treatment pool 1, a filter plate 101 is arranged at the lower end of the inside of the treatment pool 1, a lifting component for lifting the filter plate 101 is arranged on the treatment pool 1, a scraper 103 is arranged in the treatment pool 1, the scraper 103 is flush with the discharge port, a moving component for moving the scraper 103 is arranged on the treatment pool 1, mixing plates 102 are symmetrically arranged in the treatment pool 1, electric telescopic rods 5 are symmetrically arranged on the treatment pool 1, the telescopic ends of the electric telescopic rods 5 are fixedly connected to the adjacent mixing plates 102, and a drain pipe 104 is arranged at the bottom of the treatment pool 1;

[0022] The lifting assembly includes a second motor 4, which is symmetrically arranged on the treatment tank 1. A slide groove is symmetrically arranged in the treatment tank 1. A second screw rod 401 is rotatably connected in the slide groove. The second screw rod 401 is fixedly connected to the output end of the second motor 4. A second moving block 402 is threadedly connected to the second screw rod 401. The second moving block 402 is fixedly connected to the scraper 103.

[0023] The moving component includes a first motor 3, which is symmetrically arranged on one side of the treatment pool 1. The treatment pool 1 is symmetrically provided with slots, in which a first screw rod 301 is rotatably connected. The first screw rod 301 is fixedly connected to the output end of the first motor 3. A first moving block 302 is threadedly connected to the first screw rod 301, and the first moving block 302 is fixedly connected to the filter plate 101.

[0024] When it is necessary to treat the wastewater from donkey-hide gelatin production, the wastewater is introduced into the treatment tank 1, the electric telescopic rod 5 moves to drive the mixing plate 102 to stir the sewage, and then the coagulant is introduced to fully mix the coagulant and the sewage. After the mixing is completed, the sewage is allowed to stand in the treatment tank 1 for reaction. During the reaction, foam will appear on the upper end of the sewage. This is when the second motor 4 works to drive the scraper 103 to move and scrape the foam on the sewage out of the discharge port. After the reaction is completed and the foam on the sewage is scraped off, the first motor 3 works to drive the filter plate 101 to move up a distance, and then the valve of the drain pipe 104 is opened to drain the sewage. The treated sewage is discharged. When the sewage is lower than the filter plate 101, the first motor 3 drives the filter plate 101 to move up and down to quickly shake off the sewage on the filter plate 101, and then the filter plate 101 moves up to contact with the scraper 103, and then the scraper 103 moves to scrape off the sediment on the filter plate 101 and collect it in the collection box 2. Compared with the existing wastewater treatment device for donkey-hide gelatin production, the scraper 103 and the filter plate 101 are used in coordination to automatically scrape off the sediment and foam and collect them in the collection box 2, and the mixing plate 102 is used to automatically and fully mix the sewage and the coagulant, which effectively improves the treatment effect. Example 2

[0025] Reference Figure 1-Figure 4 , a device for treating wastewater from donkey-hide gelatin production is basically the same as Example 1. Furthermore, a hinge on the collecting box 2 is connected to a rotating plate 201, which is convenient for taking out the waste in the collecting box 2 for treatment.

[0026] The lower end surface of the scraper 103 is smooth, which reduces the friction between the scraper 103 and the filter plate 101 and reduces the wear on the scraper 103 .

[0027] The lower end of the discharge port is inclined to facilitate the sediment and foam to enter the collection box 2 for collection.
