Description

Technical Field

[0001] The utility model relates to the technical field of solid-liquid separation, in particular to a donkey hide wastewater filtering and processing device. Background Art

[0002] In order to ensure the stability of product quality, all industrial production enterprises have certain requirements for the quality of the raw materials used. Ejiao is no exception. The quality standard of donkey skin used in its production was first included in the "Shandong Medicinal Materials Standard (1995 Edition)". All Ejiao production enterprises purchase and use donkey skin quality standards to produce Ejiao. However, the sources of donkey skin are different, and the donkeys are slaughtered in different seasons. Even if the skin meets the donkey skin quality standards, there are differences. Therefore, it must be processed first before the subsequent processing and production can be carried out. Raw material processing is the process of soaking donkey skin for pre-treatment, including picking, weighing, soaking, dehairing, cutting, washing, and picking.

[0003] The operation steps of soaking skin: add water to the soaking pool with donkey skin, generally the amount of water added is more than 10 cm above the surface of the donkey skin (submerge the donkey skin), soak the donkey skin for 5-7 days, change the water 1-2 times a day, until the skin is soaked thoroughly. The purpose of soaking skin: first, soak the donkey skin thoroughly, which is convenient for cutting, cleaning and other operations; second, in the process of soaking skin, by changing water and turning the donkey skin, the raw materials are pre-treated to remove the dirt attached to the surface of the donkey skin to achieve the purpose of cleaning; third, by bleaching and soaking, some volatile alkaline substances produced by the donkey skin during storage can be washed away to improve the intrinsic quality of donkey gelatin. Because donkeys like to roll on the ground, rolling makes the donkey skin and fur easily mixed with dirt. In addition, in the process of purchasing donkey skin, many vendors will mix mud and sand in order to make more profits. It is not easy to completely clean up the dirt and sand before soaking. In the soaking step, the dirt and sand attached to the surface of the donkey skin need to be removed by soaking.

[0004] Soaking requires a large amount of water. The wastewater generated by soaking contains both organic impurities such as some volatile alkaline substances generated during the storage of donkey skins, and inorganic impurities such as soil, mud and sand. Before treating the wastewater generated by soaking, the wastewater generated by soaking is generally filtered first to remove inorganic impurities such as soil, mud and sand, and then the wastewater containing organic impurities is biochemically treated together with other wastewater containing organic impurities.

[0005] A filter is generally provided in the filter used for the wastewater produced by donkey skin, so as to filter the wastewater. However, after the filter has been used for a period of time, inorganic impurities such as soil, mud and sand are likely to clog the filter, thereby affecting the filtering effect of the filter. At this time, regular cleaning is required. Therefore, a donkey skin foam wastewater filtering and treatment device is provided to solve the problem of cleaning the filter inside the filter.

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example 1

[0026] Reference Figure 1-5A donkey hide and bubble hide wastewater filtering and treatment device comprises a tank body 1, a filter screen 103 is arranged in the tank body 1, the tank body 1 and the filter screen 103 are both rectangular, and also comprises: a sliding rod 203, which is slidably connected in the tank body 1, the sliding rod 203 is located below the filter screen 103, and the length of the sliding rod 203 matches the filter screen 103; multiple groups of brushes 204, which are all connected to the sliding rod 203, and one end of the brush 204 is attached to the bottom of the filter screen 103; a water pump 3, which is fixedly connected to the tank body 1, and the liquid outlet end of the water pump 3 is attached to the bottom of the filter screen 103. The tank body 1 is connected, a limit block 2031 is arranged on the sliding rod 203, a limit groove is arranged on the inner wall of the tank body 1, the limit block 2031 is slidably connected in the limit groove, the tank body 1 is connected with a tank cover 101, a feed port is arranged on the tank cover 101, a liquid outlet pipe 102 is arranged at the bottom of the tank body 1, a driving motor 201 is fixedly connected to the tank body 1, the output end of the driving motor 201 passes through the tank body 1, a screw rod 202 is fixedly connected to the output end of the driving motor 201, and the sliding rod 203 is threadedly connected to the screw rod 202.

[0027] When the device is in use, the donkey skin bubble skin wastewater to be filtered can be poured into the tank body 1 through the feed port on the tank cover 101. At this time, the donkey skin bubble skin wastewater will be filtered under the action of its own gravity (the filtration can also be promoted by pressurization. The specific implementation method can be to pour a suitable amount of donkey skin bubble skin wastewater, and then set an air pump at the feed port to promote the filtration efficiency by increasing the air pressure), and then larger mud and sand impurities will be left on the filter net 103, and the filtered donkey skin bubble skin wastewater will fall below through the filter net 103 and finally be discharged through the liquid outlet pipe 102.

[0028] After using for a period of time, soil and mud will remain on the filter screen 103, which will block the filter screen 103 and affect the filtering effect of the filter screen 103. At this time, after the internal donkey skin bubble skin waste water is completely discharged, the water pump 3 can be started (the water pump 3 is connected to the external water), and the water pump 3 sucks the external water and discharges it into the tank body 1. At this time, the liquid outlet pipe 102 and the feed port are in a closed state, so that the water will gradually increase and gradually approach the filter screen 103 (due to the top-to-bottom filtering method, impurities will accumulate above the filter screen 103, that is, most of the impurities accumulate in the upper half of the filter holes of the filter screen 103). At the same time, the drive motor 201 is started to move the sliding rod 203 slowly. At the same time, the movement of the sliding rod 203 will move the brush 204, which will then extend into the filter holes below the filter screen 103 ( The filter holes above are affected by dirt and sand. If a brush 204 is used to clean the filter holes above, it is difficult to reach into the filter holes for cleaning, so only the surface can be cleaned). The filter screen 103 is cleaned. At the same time, the rising water level will squeeze the space inside the tank body 1, thereby increasing the water pressure. Since the water first contacts the bottom of the filter screen 103, a certain air pressure will be generated, prompting some filter holes that are not seriously blocked to return to normal (the specific effect will vary greatly due to the position of the filter screen 103 and the size and sealing of the tank body 1). In this way, the filter screen 103 is cleaned. Subsequently, the liquid outlet pipe 102 can be opened to discharge smaller impurities (which can fall through the filter holes). To facilitate discharge, a secondary pipe (not shown in the figure) can be set above the filter screen 103 to discharge larger impurities (which cannot fall through the filter holes). Example 2

[0029] Reference Figure 1-5 , a donkey hide foam skin wastewater filtering and treatment device, is basically the same as Example 1, and further: a plurality of groups of protrusions 104 are fixedly connected to the bottom of the filter screen 103 at equal intervals, and knocking rods 205 matching the protrusions 104 are arranged at equal intervals on the sliding rod 203, and a groove is arranged on the sliding rod 203, and a spring member 206 is connected in the groove. The sliding rod 203 is slidably connected in the groove, and the sliding rod 203 is connected to the spring member 206.

[0030] During the movement of the sliding rod 203, the knocking rod 205 will continuously contact the protrusion 104, generating certain knocking vibrations, which can promote the separation of impurities in the brush 204 and the filter 103, making it easier to use.

[0031] The utility model can clean the filter 103 through the arrangement of the water pump 3 and the movable brush 204 to avoid clogging of the filter 103. At the same time, the knocking generated during the movement can promote the separation of inorganic impurities such as soil, mud and sand from the filter 103, making it easier to reuse the filter 103.

[0032] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
