Description

Technical Field

[0001] This utility model belongs to the field of purification structure technology, and specifically relates to a purification structure for a sediment filtration device. Background Technology

[0002] The chondroitin sulfate sedimentation filtration device is a specialized device for treating and purifying solutions or suspensions containing chondroitin sulfate. During extraction and purification, chondroitin sulfate solutions often contain impurities, insoluble particles, and other byproducts. These components need to be removed through an effective filtration device. The first step in the filtration process requires pretreatment, namely, setting up a pre-filter at the front end of the system to intercept larger particles and coarse impurities, preventing them from entering the subsequent fine filtration unit and extending the equipment's lifespan. However, after long-term use, the filter screen inside the pre-filter can become clogged with impurities, affecting its filtration efficiency. The conventional solution is to regularly clean and maintain the pre-filter to ensure its filtration effect. However, this method has the drawback of requiring disassembly of the pre-filter, increasing the difficulty of maintenance. Therefore, a new structure is proposed to address these issues. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a purification structure for a sediment filtration device to solve the problems mentioned in the background art.

[0004] This utility model is achieved through the following technical solution: a purification structure for a sediment filtration device, comprising: a filter device body and a purification component, characterized in that: a purification component for filtration is installed inside the filter device body, and the purification component includes a base for mounting a centrifuge tank.

[0005] Two sets of high-pressure nozzles for spraying are installed on the upper and lower positions of the inner wall of the filter device body. An annular groove 1 is opened at the bottom of the centrifuge tank, and an annular groove 2 matching the specifications of the annular groove 1 is opened at the top of the base. Several sets of ball bearings are provided on the inner side of the annular groove 2.

[0006] In a preferred embodiment, an inlet pipe is provided through the center of the top of the filter device body, a pumping pipe is provided through the right side of the top of the filter device body, an outlet pipe is provided through the left side of the bottom of the filter device body, and a drain pipe is provided through the right side of the bottom of the filter device body. The top of the inlet pipe is connected to the bottom of the primary solution storage tank above the filter device body, and the bottom of the outlet pipe is connected to the microfiltration membrane unit in the purification structure of the sediment filter device body. The pumping pipe is a telescopic structure, and its extension and retraction are controlled by an external control mechanism. A sealing ring is provided at the connection between the pumping pipe and the top of the filter device body, and its lower part can extend downward into the centrifuge tank. The top of the pumping pipe is connected to an external water pump, which is connected to an external wastewater collection tank. The bottom of the drain pipe is connected to an external clean water collection tank. Check valves are installed on the front of both the outlet pipe and the drain pipe. The drain pipe is used to discharge the clean water that overflows outside the centrifuge tank.

[0007] In a preferred embodiment, the centrifuge barrel has several sets of filter holes equidistantly arranged on its curved side surface, and a filter screen is provided inside the filter holes. Four sets of stirring blades are equidistantly arranged inside the centrifuge barrel. When the centrifuge barrel rotates, the stirring blades stir the solution to reduce its centrifugal force, thereby accelerating the passage of the solution through the filter holes and improving the purification efficiency.

[0008] In a preferred embodiment, a motor is installed at the center of the bottom of the base, a protective shell is provided on the outside of the motor, and a rotating shaft is provided at the top of the motor. The top of the rotating shaft passes through the top of the base and is fixed to the shaft hole opened at the center of the bottom of the centrifuge tank. The bottom of the rotating shaft is connected to the output end of the top of the motor through a coupling. The protective shell on the outside of the motor can protect the motor.

[0009] In a preferred embodiment, four sets of drainage holes are equidistantly provided in the annular area at the top of the base away from the center. The curved side of the base is welded to the inner wall of the filter device body. The drainage holes facilitate the downward collection of solution and water flow to the bottom of the filter device body.

[0010] In a preferred embodiment, the top of the base is recessed downward to form a placement groove, the radius of the placement groove matches the radius of the bottom of the centrifuge barrel, and the distance between the bottom of the centrifuge barrel and the lower inner side of the placement groove is 0.5 cm.

[0011] In a preferred embodiment, the first annular groove and the second annular groove are of the same size and are positioned vertically opposite each other. The distance between the first annular groove and the second annular groove is 0.5 cm. Several sets of ball bearings are provided between the first annular groove and the second annular groove. When the centrifuge barrel rotates, the several sets of ball bearings roll between the first annular groove and the second annular groove. Therefore, the friction between the bottom of the centrifuge barrel and the placement groove can be greatly reduced, reducing energy consumption and making the rotation of the centrifuge barrel smoother and less strenuous.

[0012] In a preferred embodiment, the water pump is a telescopic structure, with the bottom of the water pump located on the right side above the top of the centrifuge tank, and the outside of the water pump connected to the water pump.

[0013] In a preferred embodiment, the two sets of high-pressure nozzles are located at the upper and lower positions on the left side of the centrifuge tank. The high-pressure nozzles are connected to an external high-pressure water supply mechanism via hoses. The high-pressure nozzles draw water from inside the high-pressure water supply mechanism and spray it onto the outside of the centrifuge tank. The water flow sprayed by the upper and lower sets of high-pressure nozzles has a diffusion range. The width of the water flow sprayed by the two sets of high-pressure nozzles is greater than the height of the centrifuge tank. Therefore, as the centrifuge tank rotates, the two sets of high-pressure nozzles can spray the curved side of the centrifuge tank from all directions.

[0014] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting up a centrifuge tank and a base, the centrifuge tank is installed inside the placement groove opened at the top of the base, and the annular groove one at the bottom of the centrifuge tank is vertically opposite to the annular groove two opened below the placement groove. Several sets of ball bearings are provided between the annular groove one and the annular groove two. When in use, the motor drives the centrifuge tank to rotate. After the solution enters the centrifuge tank, due to the stirring action of the four sets of stirring blades inside the centrifuge tank, the solution has centrifugal force inside the centrifuge tank. Therefore, it will flow outward through several sets of filter holes opened on the side of the centrifuge tank and be filtered by the filter screen inside the filter holes, thereby achieving the filtration of the solution. When the centrifuge tank rotates, several sets of ball bearings rotate inside the annular groove one and the annular groove two, thereby reducing the friction force on the centrifuge tank and making the rotation more effortless. The final effect is that the high-speed rotation of the centrifuge tank can improve the purification efficiency. Through the several sets of filter holes opened on the side of the centrifuge tank, the solution can be filtered efficiently, which significantly improves the purification effect of the purification component.

[0015] 2. By installing high-pressure nozzles and a water suction pipe, impurities accumulate on the inside of the filter screen after prolonged use, causing clogging and affecting its normal operation. When cleaning is needed, the centrifuge tank rotates normally, and two sets of high-pressure nozzles are activated to spray water from the outside to the inside of the filter screen, thus dislodging the impurities adhering to the screen mesh and pushing them into the centrifuge tank. Since the centrifuge tank is rotating, the sides can be sprayed from all directions without the two sets of high-pressure nozzles remaining in the same position. Then, the water suction pipe extends downwards to below the water level inside the centrifuge tank to remove the water containing impurities, thus clearing the impurities from the inside of the centrifuge tank. The final effect is that the impurities on the filter screen can be removed without disassembling the main filter unit, greatly increasing the efficiency of maintenance and cleaning.

[0025] 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 one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figures 1 to 5 A purification structure for a sediment filtration device includes: a filter device body 100 and a purification component, characterized in that: a purification component for filtration is installed inside the filter device body 100, and the purification component includes a base 300 for mounting a centrifuge tank 200.

[0027] Two sets of high-pressure spray nozzles 150 for spraying are installed on the upper and lower positions of the inner wall of the filter body 100. The bottom of the centrifuge tank 200 is provided with an annular groove 210, and the top of the base 300 is provided with an annular groove 320 that matches the specifications of the annular groove 210. Several sets of ball bearings 330 are provided inside the annular groove 320.

[0028] A liquid inlet pipe 110 is installed at the center of the top of the filter body 100; a water extraction pipe 140 is installed on the right side of the top of the filter body 100; a liquid outlet pipe 120 is installed on the left side of the bottom of the filter body 100; and a drain pipe 130 is installed on the right side of the bottom of the filter body 100. The top of the liquid inlet pipe 110 is connected to the bottom of the primary solution storage tank above the filter body 100; the bottom of the liquid outlet pipe 120 is connected to the microfiltration membrane unit in the purification structure of the sediment filter body 100; and the water extraction pipe 140... 0 is a telescopic structure, and its extension and retraction are controlled by an external control mechanism. A sealing ring is provided at the connection between the water pump 140 and the top of the filter device body 100. The bottom of the water pump 140 can extend downward into the centrifuge tank 200. The top of the water pump 140 is connected to an external water pump, which is connected to an external wastewater collection tank. The bottom of the drain pipe 130 is connected to an external clean water collection tank. Both the liquid outlet pipe 120 and the drain pipe 130 are equipped with check valves on the front. The drain pipe 130 is used to discharge the clean water that overflows outside the centrifuge tank 200.

[0029] Several sets of filter holes are equidistantly arranged on the curved side of the centrifuge tank 200. A filter screen 220 is provided inside the filter holes. Four sets of stirring blades are equidistantly arranged inside the centrifuge tank 200. When the centrifuge tank 200 rotates, the stirring blades stir the solution to reduce the centrifugal force, thereby accelerating the passage of the solution through the filter holes and improving the purification efficiency.

[0030] A motor 310 is installed at the center of the bottom of the base 300. A protective shell is provided on the outside of the motor 310. A rotating shaft is provided on the top of the motor 310. The top of the rotating shaft passes through the top of the base 300 and is fixed to the shaft hole opened at the center of the bottom of the centrifuge tank 200. The bottom of the rotating shaft is connected to the output end of the top of the motor 310 through a coupling. The protective shell on the outside of the motor 310 can protect the motor 310.

[0031] The base 300 has four sets of drainage holes at equal intervals in the annular area away from the center. The curved side of the base 300 is welded to the inner wall of the filter device body 100. The drainage holes facilitate the downward collection of solution and water to the bottom of the filter device body 100.

[0032] The top of the base 300 is recessed downward to form a placement groove. The radius of the placement groove matches the radius of the bottom of the centrifuge tank 200. The distance between the bottom of the centrifuge tank 200 and the lower inner side of the placement groove is 0.5cm.

[0033] The annular groove 210 and the annular groove 320 are identical in size and positioned opposite each other. The distance between the annular groove 210 and the annular groove 320 is 0.5 cm. Several sets of ball bearings 330 are provided between the annular groove 210 and the annular groove 320. When the centrifuge tank 200 rotates, the several sets of ball bearings 330 roll between the annular groove 210 and the annular groove 320. Therefore, the friction between the bottom of the centrifuge tank 200 and the placement groove can be greatly reduced, reducing energy consumption and making the rotation of the centrifuge tank 200 smoother and less strenuous.

[0034] The water pump 140 is a telescopic structure. The bottom of the water pump 140 is located on the right side above the top of the centrifuge tank 200, and the outside of the water pump 140 is connected to the water pump.

[0035] Two sets of high-pressure nozzles 150 are located on the upper and lower left sides of the centrifuge tank 200. The high-pressure nozzles 150 are connected to an external high-pressure water supply mechanism through hoses. The high-pressure nozzles 150 draw water from inside the high-pressure water supply mechanism and spray it on the outside of the centrifuge tank 200. The water flow sprayed by the two sets of high-pressure nozzles 150 has a diffusion range. The width of the water flow sprayed by the two sets of high-pressure nozzles 150 is greater than the height of the centrifuge tank 200. Therefore, as the centrifuge tank 200 rotates, the two sets of high-pressure nozzles 150 can spray the curved side of the centrifuge tank 200 in all directions.

[0036] Example 1: Please refer to Figures 1 to 5 In actual use, the top of the inlet pipe 110 is connected to the bottom of the primary solution storage tank, the bottom of the outlet pipe 120 is connected to the microfiltration membrane unit in the purification structure of the sediment filtration device body 100, the water pump 140 is a telescopic structure that can extend downwards into the centrifuge tank 200, the top of the water pump 140 is connected to an external water pump, the water pump is connected to an external wastewater collection tank, and the bottom of the drain pipe 130 is connected to an external clean water collection tank. Both the outlet pipe 120 and the drain pipe 130 are equipped with check valves on their front sides to ensure proper backflow prevention. When in use, first turn on the motor 310 under the base 300, so that the motor 310 rotates in the forward direction and drives the centrifuge tank 200 placed inside the top slot of the base 300 to rotate in the forward direction. The chondroitin sulfate raw material solution enters the centrifuge tank 200 inside the filter device body 100 through the liquid inlet pipe 110 and collects inside the centrifuge tank 200. The centrifuge tank 200 is equipped with four sets of stirring blades on the inside, which can stir the solution to make it have centrifugal force and discharge it outward through several sets of filter holes on the side of the centrifuge tank 200.

[0037] When the centrifuge tank 200 rotates, several sets of ball bearings 330 between the annular groove 210 at its bottom and the annular groove 320 on its inner side will roll along the annular groove 210 and the annular groove 320 respectively. This greatly reduces the friction at the bottom of the centrifuge tank 200, making its rotation smoother and less strenuous. When the solution passes through the filter holes, it is filtered by the filter screen 220 inside the filter holes, thus achieving a filtration and purification effect. It should be noted that due to the existence of the filter holes, once the solution enters the centrifuge tank 200, it will naturally flow out of the filter holes even if the centrifuge tank 200 is not rotating. Furthermore, the rate at which the solution falls matches the rate at which it flows out through the filter holes. This means that the solution will not fail to collect inside the centrifuge tank 200 due to excessive leakage, nor will it overflow from the centrifuge tank 200 due to excessive inflow. Therefore, the solution can collect inside the centrifuge tank 200 without hindering the filtration effect of the filter screen 220 inside the filter holes. The rotation of the centrifuge tank 200 accelerates the rate at which the solution passes through the filter holes, thus improving the filtration efficiency. Since several sets of filter holes are provided on the side of the centrifuge tank 200, the filtration effect on the solution is greatly increased, making the purification effect of the purification component more significant.

[0038] Example 2: Please refer to Figure 1 and Figure 2 After long-term use, impurities tend to accumulate on the filter screen 220 inside the filter holes. When impurities adhere to the mesh of the filter screen 220, it will reduce the filtration and purification effect of the filter screen 220, and in severe cases, it may cause the filter screen 220 to fail. Therefore, it is necessary to clean the impurities at the mesh. First, ensure that the solution inside the centrifuge tank 200 is completely drained. Then, close the check valve at the outlet pipe 120 and keep the check valve at the drain pipe 130 open. Then, keep the motor 310 rotating and drive the centrifuge tank 200 to rotate. Water is sprayed onto the side of the centrifuge tank 200 through two sets of high-pressure nozzles 150 installed at the upper and lower positions on the left inner wall of the main body of the device. The water flow sprayed by the high-pressure nozzles 150 has a certain diffusion range. Therefore, the spray width formed by the water flow sprayed by the two sets of high-pressure nozzles 150 is equal to the height of the centrifuge tank 200.

[0039] Under the spray of the high-pressure nozzle 150, water is sprayed from the outside of the filter holes to the inside, passing through the filter screen 220 and being sprayed into the centrifuge tank 200. Therefore, when the water is sprayed from the outside of the filter screen 220 to the inside, impurities can be carried away by the water flow and enter the interior of the centrifuge tank 200. Since the centrifuge tank 200 is always rotating, the filter screens 220 in several filter holes can be thoroughly cleaned by two sets of high-pressure nozzles 150. After the water flow mixed with impurities collects inside the centrifuge tank 200, the water pump is then controlled to extend downward so that the bottom of the water pump 140 is below the interface between the water flow inside the centrifuge tank 200 and the water flow inside the centrifuge tank 200. Then, the water pump is activated to extract the water flow mixed with impurities. It should be noted that when the water flow is sprayed into the centrifuge tank 200 and collects inside the centrifuge tank 200, the water flow will flow outward along the filter holes and collect in the main body 1 of the filter device. At the bottom of the centrifuge tank 200, since the outlet pipe 120 is closed and the drain pipe 130 is open, water will be discharged through the drain pipe 130. Some water will accumulate inside the outlet pipe 120. At this time, the connection between the bottom of the outlet pipe 120 and the microfiltration membrane unit can be disconnected, the water can be drained, and then reconnected to prevent the water from affecting the concentration of the solution. In order to thoroughly clean the filter screen 220, the cleaning time can be extended to achieve a complete cleaning effect (the extension and retraction control of the motor 310, the high-pressure nozzle 150, the water pump 140 and the water pump are all existing technologies, and their internal structure and working principle will not be described in detail here). Therefore, the final effect is that the filter screen 220 can be cleaned by spraying the centrifuge tank 200 with the high-pressure nozzle 150 without disassembling the filter device body 100, which greatly improves the efficiency and convenience of maintenance and cleaning.
