Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically a microfiltration machine. Background Technology

[0002] A microfilter is a filter that uses a screen to trap fine suspended matter. It has a barrel-shaped frame with a drum rotating around a central axis, and the drum is covered with a filter screen. It can be used for filtering raw water in water treatment plants and removing algae, water fleas, and other planktonic organisms. It can also be used for filtering industrial water, recovering free substances from industrial wastewater, and for the final treatment of sewage.

[0003] During the microfiltration process, impurities will settle to the bottom of the device. In addition, smaller impurities will inevitably get stuck in the filter holes. Over time, this will cause the filter holes to become clogged, thus affecting the filtration efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a microfilter to solve the problems that during the microfilter filtration process, impurities will settle to the bottom of the device, and small impurities will inevitably get stuck in the filter holes. Long-term operation will cause the filter holes to become clogged, thus affecting the filtration efficiency.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to a microfiltration machine, including a mounting frame portion, on which a mounting plate portion is fixedly mounted, comprising:

[0007] The mounting bracket includes two fixed plates fixedly mounted on the mounting bracket. A rotating shaft is rotatably mounted on the two fixed plates. A rotating cylinder is rotatably mounted on the rotating shaft. Two rotating rollers are fixedly sleeved on the rotating shaft. Two connecting plates are fixedly mounted on the two rotating rollers respectively. The front of the rotating shaft passes through the corresponding fixed plate. A drive motor is fixedly mounted on the front of the corresponding fixed plate. The output end of the drive motor is fixedly connected to the rotating shaft.

[0008] Furthermore, several connecting plates are grouped in pairs, and scrapers are fixedly installed on several groups of connecting plates. C-shaped triangular plates are slidably installed inside several scrapers, and several telescopic C-shaped triangular plates pass through several scrapers.

[0009] Furthermore, two circular plates are fixedly fitted onto each of the several C-shaped triangular plates, and limit springs are fixedly installed on the sides of the several telescopic circular plates that are far apart from each other. The ends of the several telescopic limit springs that are far apart from each other are fixedly connected to the corresponding scrapers.

[0010] Furthermore, two fixing rods are fixedly installed on the mounting frame, and an inverted cylinder is fixedly installed on the two fixing rods. The inner wall of the inverted cylinder is fixedly connected to the rotating cylinder.

[0011] Furthermore, the rotating cylinder has several filter holes, and the inner wall of the rotating cylinder has several trapezoidal grooves, each of which is adapted to a number of C-shaped triangular plates.

[0012] Furthermore, two closing plates are fixedly installed on the inner wall of the C-shaped cylinder, and the inner sides of the two closing plates are fixedly connected to the rotating cylinder. A discharge port is opened on the outer wall of the C-shaped cylinder, an L-shaped drain pipe is fixedly installed at the bottom of the C-shaped cylinder, and an L-shaped water inlet pipe is fixedly installed at the top of the rotating cylinder.

[0013] Furthermore, the mounting plate includes a water pump fixedly mounted on the top of the mounting plate, with an inlet pipe fixedly mounted at the input end of the water pump and an outlet pipe fixedly mounted at the output end of the water pump.

[0014] Furthermore, a strip box is fixedly installed on the back of the L-shaped drain pipe, the end of the outlet pipe is connected to the strip box, a telescopic spring is fixedly installed on the inner wall of the back of the strip box, an L-shaped limiting slide plate is fixedly installed on the front of the telescopic spring, the L-shaped limiting slide plate is slidably connected to the strip box, and the strip box is connected to the L-shaped drain pipe.

[0015] This utility model has the following beneficial effects:

[0016] (1) This utility model is a microfiltration machine. When in use, the water to be filtered flows into the rotating cylinder through the L-shaped inlet pipe. The drive motor is started, and the drive motor drives the rotating shaft to rotate. The rotating shaft drives the rotating roller to rotate. The rotating roller drives the connecting plate to rotate. The connecting plate drives the scraper to rotate. The scraper rotates along the inner wall of the rotating cylinder and drives the impurities in the water flowing into the rotating cylinder to rotate. When the scraper rotates to a higher position in the rotating cylinder, the impurities will fall under the action of their center of gravity. Due to inertia, the impurities will be thrown out from the discharge port. The corresponding water will be filtered through the filter holes on the rotating cylinder and flow into the C-shaped cylinder and discharged through the L-shaped drain pipe. During the rotation process, the scraper can effectively prevent impurities from accumulating at the bottom of the rotating cylinder. Under the action of centrifugal force and gravity, the impurities are discharged from the device, ensuring that the water can be filtered normally and reducing the burden of cleaning impurities.

[0017] (2) The microfilter of this utility model will also drive the C-shaped triangular plate to rotate during the rotation of the scraper. Since the limiting spring is always in a compressed state, when the C-shaped triangular plate passes through the trapezoidal groove, the limiting spring will push the C-shaped triangular plate into the trapezoidal groove. During the continuous rotation of the scraper, the C-shaped triangular plate will continuously enter the trapezoidal groove and leave the trapezoidal groove, and generate slight vibration. The vibration will loosen the impurities remaining on the filter holes and the inner wall of the rotating cylinder, reduce the chance of impurities adhering to the device, and reduce the pressure on the cleaning device.

[0018] (3) When the microfiltration machine of this utility model needs to be cleaned, the water pump is started and the water pump sends water to the strip box through the water outlet pipe. The water will push the L-shaped limiting slide into the L-shaped drain pipe and push against the inner wall of the L-shaped drain pipe. At this time, the extension spring is stretched and deformed, and the water will enter the C-shaped cylinder from the L-shaped drain pipe. Since the filter holes on the rotating cylinder are small, the water pressure will increase when the water enters the rotating cylinder from the C-shaped cylinder, and the impurities stuck in the filter holes will be sprayed out. During the rotation of the scraper, the impurities will be discharged from the discharge port, further improving the cleaning effect of the device.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0029] 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.

[0030] This utility model provides, for example Figure 1-6A microfiltration machine is shown, comprising a mounting frame 1, on which a mounting plate 2 is fixedly mounted. The mounting frame 1 includes two fixed plates 101 fixedly mounted on it. A rotating shaft 102 is rotatably mounted on the two fixed plates 101. A rotating cylinder 103 is rotatably mounted on the rotating shaft 102. Two rotating rollers 104 are fixedly sleeved on the rotating shaft 102. Two connecting plates 105 are fixedly mounted on each of the two rotating rollers 104. The front of the rotating shaft 102 passes through the corresponding fixed plate 101. A drive motor 118 is fixedly mounted on the front of the corresponding fixed plate 101, and the output end of the drive motor 118 is fixedly connected to the rotating shaft 102. Several connecting plates 105 are arranged in pairs. Scrapers 106 are fixedly mounted on each pair of connecting plates 105. C-shaped triangular plates 107 are slidably mounted within each scraper 106. Several telescopic C-shaped triangular plates 107 pass through each scraper 106. Several C-shaped triangular plates 107 are each fixedly fitted with two circular plates 108. Limiting springs 109 are fixedly installed on the opposite sides of the telescopic circular plates 108. The opposite ends of the telescopic limiting springs 109 are fixedly connected to corresponding scrapers 106. Two fixing rods 110 are fixedly installed on the mounting frame 1. C-shaped cylinders 111 are fixedly installed on the two fixing rods 110. The inner wall of the C-shaped cylinders 111 is fixedly connected to a rotating cylinder 103. The rotating cylinder 103 has several filter holes 112 and several trapezoidal grooves 113 on its inner wall. These telescopic trapezoidal grooves 113 are respectively adapted to fit the C-shaped triangular plates 107. Two closed plates 114 are fixedly installed on the inner wall of the chamfered cylinder 111. The inner sides of the two closed plates 114 are fixedly connected to the rotating cylinder 103. A discharge port 115 is opened on the outer wall of the chamfered cylinder 111. An L-shaped drain pipe 116 is fixedly installed at the bottom of the chamfered cylinder 111. An L-shaped water inlet pipe 117 is fixedly installed at the top of the rotating cylinder 103.

[0031] During use, the water to be filtered flows into the rotating cylinder 103 through the L-shaped inlet pipe 117. The drive motor 118 is started, causing the rotating shaft 102 to rotate. The rotating shaft 102 then rotates the rotating roller 104, which in turn rotates the connecting plate 105. The connecting plate 105 then rotates the scraper 106. The scraper 106 rotates along the inner wall of the rotating cylinder 103, causing impurities in the water flowing into the rotating cylinder 103 to rotate. When the scraper 106 rotates to a higher position inside the rotating cylinder 103, the impurities fall due to their center of gravity. Due to inertia, the impurities are thrown out from the discharge port 115, and the corresponding water flows through the filter holes 112 on the rotating cylinder 103 into the U-shaped cylinder 111 and is discharged through the L-shaped drain pipe 116. The scraper 106 effectively filters water during its rotation. To prevent impurities from accumulating at the bottom of the rotating drum 103, the impurities are discharged from the device under the action of centrifugal force and gravity, ensuring that water can be filtered normally and reducing the burden of cleaning impurities. During the rotation of the scraper 106, the C-shaped triangular plate 107 will also rotate. Since the limiting spring 109 is always in a compressed state, when the C-shaped triangular plate 107 passes through the trapezoidal groove 113, the limiting spring 109 will push the C-shaped triangular plate 107 into the trapezoidal groove 113. During the continuous rotation of the scraper 106, the C-shaped triangular plate 107 will continuously enter and leave the trapezoidal groove 113, and generate slight vibration. The vibration will loosen the impurities remaining on the filter holes 112 and the inner wall of the rotating drum 103, reducing the chance of impurities adhering to the device and reducing the pressure on the cleaning device.

[0032] Mounting plate 2 includes a water pump 201 fixedly mounted on the top of mounting plate 2. A water inlet pipe 202 is fixedly mounted at the input end of the water pump 201, and a water outlet pipe 203 is fixedly mounted at the output end of the water pump 201. A strip box 204 is fixedly mounted on the back of the L-shaped drain pipe 116. The end of the water outlet pipe 203 is connected to the strip box 204. A telescopic spring 205 is fixedly mounted on the inner wall of the back of the strip box 204. An L-shaped limiting slide plate 206 is fixedly mounted on the front of the telescopic spring 205. The L-shaped limiting slide plate 206 is slidably connected to the strip box 204. The strip box 204 is connected to the L-shaped drain pipe 116.

[0033] When the device needs cleaning, start the water pump 201. The water pump 201 sends water to the strip box 204 through the outlet pipe 203. The water pushes the L-shaped limiting slide plate 206 into the L-shaped drain pipe 116 and pushes against the inner wall of the L-shaped drain pipe 116. At this time, the extension spring 205 is stretched and deformed, and the water enters the C-shaped cylinder 111 from the L-shaped drain pipe 116. Since the filter holes 112 on the rotating cylinder 103 are small, the water pressure will increase when the water enters the rotating cylinder 103 from the C-shaped cylinder 111, and the impurities stuck in the filter holes 112 will be sprayed out. During the rotation of the scraper 106, the impurities will be discharged from the discharge port 115, further improving the cleaning effect of the device.

[0034] The working principle of the casting mold for ultra-thin-walled lightweight metal castings provided by this utility model is as follows: During use, water requiring filtration flows into the rotating cylinder 103 through the L-shaped inlet pipe 117. The drive motor 118 is started, driving the rotating shaft 102 to rotate. The rotating shaft 102 drives the rotating roller 104 to rotate, which in turn drives the connecting plate 105 to rotate. The connecting plate 105 drives the scraper 106 to rotate. The scraper 106 rotates along the inner wall of the rotating cylinder 103, causing impurities in the water flowing into the rotating cylinder 103 to rotate. When the scraper 106 rotates to a higher position within the rotating cylinder 103, the impurities fall under their own weight. Due to inertia, the impurities are thrown out from the discharge port 115. Correspondingly, the water is filtered through the filter holes 112 on the rotating cylinder 103 and flows into the U-shaped cylinder 111, then discharged through the L-shaped drain pipe 116. During rotation, the scraper 106 effectively prevents impurities from accumulating at the bottom of the rotating cylinder 103. Under the action of centrifugal force and gravity, the impurities are discharged from the device, ensuring that the water can be filtered normally and reducing the burden of cleaning impurities. During the rotation of the scraper 106, the C-shaped triangular plate 107 will also rotate. Since the limiting spring 109 is always in a compressed state, when the C-shaped triangular plate 107 passes through the trapezoidal groove 113, the limiting spring 109 will push the C-shaped triangular plate 107 into the trapezoidal groove 113. During the continuous rotation of the scraper 106, the C-shaped triangular plate 107 will continuously enter and leave the trapezoidal groove 113, and generate slight vibration. The vibration will loosen the impurities remaining on the filter holes 112 and the inner wall of the rotating cylinder 103, reducing the chance of impurities adhering to the device and reducing the pressure on the cleaning device.

[0035] When the device needs cleaning, start the water pump 201. The water pump 201 sends water to the strip box 204 through the outlet pipe 203. The water pushes the L-shaped limiting slide plate 206 into the L-shaped drain pipe 116 and pushes against the inner wall of the L-shaped drain pipe 116. At this time, the extension spring 205 is stretched and deformed, and the water enters the C-shaped cylinder 111 from the L-shaped drain pipe 116. Since the filter holes 112 on the rotating cylinder 103 are small, the water pressure will increase when the water enters the rotating cylinder 103 from the C-shaped cylinder 111, and the impurities stuck in the filter holes 112 will be sprayed out. During the rotation of the scraper 106, the impurities will be discharged from the discharge port 115, further improving the cleaning effect of the device.

Clearly, many modifications and variations can be made based on the content of this specification.
