Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater filtration device for the processing steps of raw materials in donkey-hide gelatin production. Background Technology

[0002] In the production of donkey-hide gelatin, raw material processing involves pre-treatment of donkey hides by soaking them. This includes sorting, weighing, soaking, hair removal, cutting, washing, and stacking. Sorting: According to quality standards, the hides are sorted and impurities such as sawdust, ironware, stones, grass roots, leaves, and miscellaneous hides are removed. The hides and impurities are then sorted and stacked for further processing. Weighing: The sorted and qualified donkey hides are weighed and accurately added to the soaking tank according to the planned quantity. Soaking: Water is added to the soaking tank, generally at least 10 cm above the hide surface (enough to submerge the hides). The hides are soaked for 5-7 days, with the water changed 1-2 times daily until thoroughly soaked. Hair removal: The soaked hides are placed on a hair removal rack, and the hair is scraped off with a hair removal knife. Cutting the hide: In the production process of donkey-hide gelatin, cutting the hide involves placing the soaked and dehaired donkey hide on a cutting rack and cutting it into squares with sides of approximately 40cm. Alternatively, the soaked and dehaired donkey hide can be placed in a cutting machine and cut into small pieces of the specified size. Sorting the hide: The soaked, cut, and washed donkey hide is placed in a clean sorting container (such as a steaming ball), a certain amount of baking soda and a certain proportion of water are added, and steam is introduced to heat it until the donkey hide curls up. The baking soda solution is then released. Water is then added again to wash the donkey hide until it is clean and ready for use.

[0003] The processing of raw materials generates a large amount of wastewater. The wastewater discharged during the soaking and washing of the hides accounts for about one-third of the total wastewater, and the main pollutants in the water are insoluble substances such as mud, sand, donkey hair, and fragments of donkey hide. The wastewater from the hide-collecting process mainly contains organic oils. To facilitate subsequent wastewater treatment, this wastewater is generally filtered before being discharged into a collection tank for unified treatment with other wastewater. Existing wastewater filtration devices, after filtering hair, tend to trap hair in the filter mesh, making it difficult to remove during cleaning and affecting the cleaning effect. Furthermore, existing filtration devices cannot effectively filter out fine debris in the wastewater, resulting in inconsistent wastewater treatment quality. Utility Model Content

[0004] The technical problem this invention aims to solve is to overcome existing defects and provide a wastewater filtration device for the processing of raw materials in donkey-hide gelatin production. Through the setting of a fixed frame, side frame, clamping strip, longitudinal filter lines, and transverse filter lines, the longitudinal and transverse filter lines form a filter mesh after being compressed, thereby filtering hair. When cleaning is required, the two side frames are separated, allowing the longitudinal and transverse filter lines to separate. Hair can then be removed from the longitudinal and transverse filter lines simply by rinsing with water, improving cleaning efficiency and effectively solving the problems in the background technology.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a wastewater filtration device for the processing of raw materials for donkey-hide gelatin production, comprising a filter box, an activated carbon layer disposed on the bottom inner side of one end of the filter box, a sand and gravel layer disposed on the upper side of the activated carbon layer, a fixing frame disposed on the upper side of the sand and gravel layer, a horizontal filter screen line disposed on the lower inner side of the fixing frame, a vertical filter screen line disposed on the upper side of the horizontal filter screen line, and a frame disposed on the outer ring side of both the horizontal and vertical filter screen lines, with neodymium magnets disposed on the opposite sides of the two frame sides.

[0006] Furthermore, a retaining strip is provided on the inner side of the filter box corresponding to the position of the fixing frame, and a baffle is provided at one end of the retaining strip.

[0007] Furthermore, a coarse filter screen is provided on the upper side of the baffle, and rotating arms are provided at both ends of the upper edge of the coarse filter screen.

[0008] Furthermore, a cylinder is hinged to the rotating arm, and a water inlet pipe is installed on the side of one end of the filter box.

[0009] Furthermore, a drain pipe is provided on the lower side of the filter box away from the water inlet pipe, and the lower edge of the coarse filter screen contacts the bottom side of the filter box.

[0010] Furthermore, a perforated plate is installed at the contact position between the drain pipe and the filter box, the fixing frame is connected to the side frame through a slot, and the two side frames are connected by the rubidium magnet.

[0011] Furthermore, the baffle is sealed to the inner wall of the filter box.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses a fixed frame, a side frame, a locking strip, longitudinal filter lines, and transverse filter lines to form a filter mesh after the longitudinal and transverse filter lines are pressed together, which can filter hair. When cleaning is needed, the two side frames are separated, so that the longitudinal and transverse filter lines are separated. Hair can be removed from the longitudinal and transverse filter lines by rinsing with water, thus improving cleaning efficiency.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-4 This embodiment provides a technical solution: a wastewater filtration device for the processing of raw materials for donkey-hide gelatin production, including a filter box 2. An activated carbon layer 14 is provided on the bottom side of one end of the filter box 2. A sand and gravel layer 13 is provided on the upper side of the activated carbon layer 14. A fixing frame 4 is provided on the upper side of the sand and gravel layer 13. A horizontal filter screen line 5 is provided on the lower side inside the fixing frame 4. A vertical filter screen line 6 is provided on the upper side of the horizontal filter screen line 5. A frame 8 is provided on the outer ring side of both the horizontal filter screen line 5 and the vertical filter screen line 6. Rubidium magnets 7 are provided on the opposite sides of the two frame 8.

[0022] like Figures 1-4As shown, wastewater is transported into the filter box 2 through the inlet pipe 1. The coarse filter screen 3 can perform preliminary filtration of the wastewater, removing larger impurities. After preliminary filtration, the wastewater flows over the baffle 9 and into one end of the filter box 2. The cross grid formed by the intersection of the horizontal filter screen 5 and the vertical filter screen 6 can filter hair and other smaller impurities in the wastewater. The filtered water flows onto the upper side of the sand and gravel layer 13. The sand and gravel layer 13 and the activated carbon layer 14 can adsorb and filter smaller debris in the wastewater, ensuring the treatment effect of the wastewater. When cleaning is required, the frame 8 of the horizontal filter screen 5 and the vertical filter screen 6 is removed from the fixed frame 4, and then the two frame frames 8 are separated, thereby separating the horizontal filter screen 5 and the vertical filter screen 6. The horizontal filter screen 5 and the vertical filter screen 6 are rinsed with water to wash away the hair on the horizontal filter screen 5 and the vertical filter screen 6, improving the cleaning efficiency.

[0023] A retaining strip 10 is provided on the inner side of the filter box 2 corresponding to the position of the fixed frame 4. A baffle 9 is provided at one end of the retaining strip 10. The baffle 9 can divide the inner side of the filter box 2 into two spaces. The retaining strip 10 can support the fixed frame 4 and ensure that the fixed frame 4 is effectively secured.

[0024] A coarse filter screen 3 is provided on the upper side of the baffle 9. Rotating arms 11 are provided at both ends of the upper edge of the coarse filter screen 3. The cylinder 12 pushes the rotating arms 11 to rotate, thereby causing the coarse filter screen 3 to rotate around the upper edge, causing the large impurities filtered on the coarse filter screen 3 to flip upward, thereby causing the impurities on the coarse filter screen 3 to be removed from the water, making it convenient to clean the impurities on the coarse filter screen 3.

[0025] A cylinder 12 is hinged to the rotating arm 11, and a water inlet pipe 1 is installed on the side of one end of the filter box 2.

[0026] A drain pipe 15 is provided on the lower side of the filter box 2 away from the water inlet pipe 1, and the lower edge of the coarse filter screen 3 is in contact with the inner bottom side of the filter box 2.

[0027] A perforated plate is installed at the contact position between the drain pipe 15 and the filter box 2. The fixed frame 4 and the frame 8 are connected by a slot. The two frames 8 are connected by a neodymium magnet 7. The neodymium magnet 7 can make the two frames 8 stably connected together, so that the longitudinal filter screen line 6 and the transverse filter screen line 5 are tightly attached to form a filter screen.

[0028] The baffle 9 is sealed to the inner wall of the filter box 2.

[0029] The working principle of the wastewater filtration device for the raw material processing steps in donkey-hide gelatin production provided by this utility model is as follows: Figures 1-4As shown, wastewater is fed into the filter box 2 through the inlet pipe 1. The coarse filter screen 3 performs preliminary filtration, removing larger impurities. After preliminary filtration, the wastewater flows over the baffle 9 and into one end of the filter box 2. The cross-shaped mesh formed by the intersecting horizontal and vertical filter screen lines 5 and 6 filters out hair and other smaller impurities in the wastewater. The filtered water flows onto the upper side of the sand and gravel layer 13. The sand and gravel layer 13 and the activated carbon layer 14 adsorb and filter smaller debris in the wastewater, ensuring the treatment effect of the wastewater. When cleaning is required, the frame 8 is removed from the fixed frame 4, and the two frames 8 are separated, thereby separating the horizontal filter line 5 and the vertical filter line 6. The horizontal filter line 5 and the vertical filter line 6 are rinsed with water to remove the hair on them, improving cleaning efficiency. The wastewater flowing through the horizontal filter line 5 and the vertical filter line 6 enters the sand and gravel layer 13 and the activated carbon layer 14, thereby effectively adsorbing and filtering the debris pollutants in the wastewater, ensuring the quality of wastewater treatment.

[0030] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
