Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of purification and dust removal, and relates to a purification device, in particular to a purification device of a four-station polishing machine. BACKGROUND

[0002] During mechanical polishing and grinding work, smoke and dust are generated, which affects personal health and the environment. Moreover, dust is a flammable and explosive substance, and if there is a spark, an explosion is likely to occur. Therefore, during polishing and grinding of parts, polishing and grinding wet dust removal equipment is usually applied. This equipment can absorb dust and smoke, and purify dust and other particulate matter through wet processing, thereby meeting the requirements of explosion prevention and dust removal.

[0003] Chinese Patent Application No. 201810274915.X discloses an intelligent polishing and grinding explosion-proof dust removal all-in-one machine, which includes a polishing and grinding machine and left and right suction dust removal boxes arranged on both sides of the polishing and grinding machine. The polishing and grinding machine and the left and right suction dust removal boxes are connected to respective centrifugal fans and suction ducts. The left and right suction dust removal boxes include left and right suction port water curtain, water spray dust removal chambers and sewage tanks connected in sequence. Dust generated during the operation of the polishing and grinding machine is washed and settled by the left suction port water curtain and the left suction port water curtain under the suction of the centrifugal fan, and is then settled and adsorbed in the water spray dust removal chamber. The dust is washed and settled by the water flow and flows into the sewage tank. The purified air is discharged from the air duct. In the above structure, the dust is washed and settled by the spray nozzles in the water spray dust removal chamber and then enters the sewage tank, thereby achieving the effects of purification and filtration. However, a part of the dust generated during polishing and grinding is fiber, which has the characteristics of adsorption and can adsorb water and other dust impurities, resulting in an excessively large volume. Under the action of spraying, the fiber falls and settles at the bottom of the water spray dust removal chamber, which can easily cause blockage of the sewage discharge system. Moreover, the polishing and grinding explosion-proof dust removal all-in-one machine has general dust removal effect. Therefore, it is urgent to solve the above problems. SUMMARY

[0004] The present application aims to solve the above problems in the prior art and provides a purification device of a four-station polishing machine. The present application solves the technical problem of low purification efficiency of the existing polishing machine.

[0005] The object of the present application can be achieved by the following technical solutions:

[0006] The utility model provides a purification device of four station polishing machine, including the shell with upper chamber and lower chamber, the upper chamber top is equipped with the fan, be equipped with the air duct on the shell and communicate upper chamber and lower chamber, be equipped with water curtain board no.

[0007] The utility model discloses a purification device of four station polishing machine, including the shell with upper chamber and lower chamber, the upper chamber top is equipped with the fan, be equipped with the air duct on the shell and communicate upper chamber and lower chamber. The upper chamber is used for installing the fan, and the lower chamber is used for the chamber for inhaling the dust. Water curtain board no. and water curtain board no. are oppositely arranged in the lower chamber, and water curtain board no. and water curtain board no. have the continuous water curtain that flows, that is, the water flow adheres to the surface of water curtain board no. or water curtain board no. and flows, which can adsorb the dust particles sucked into the lower chamber. The water curtain is continuously flowing, that is, the circulating water flow continuously evolves the dust, so as to achieve the effect of purifying the air.

[0008] The arc-shaped part one is arranged on the water curtain plate one, the arc-shaped part two is arranged on the water curtain plate two, and the arc-shaped part one and the arc-shaped part two are oppositely curved. The blocking piece in a strip shape is arranged between the arc-shaped part one and the arc-shaped part two. The recessed arc-shaped surface one is arranged on one side of the arc-shaped part one of the blocking piece. The recessed arc-shaped surface two is arranged on the other side of the arc-shaped part two of the blocking piece. The blocking piece in a strip shape is arranged between the arc-shaped part one and the arc-shaped part two, so that the blocking piece has gaps on both sides between the water curtain plate one and the water curtain plate two. The water flow on the water curtain plate one and the water curtain plate two is partially sucked up from the gaps on both sides of the blocking piece through the suction caused by the opening of the channel of the fan. The recessed arc-shaped surface one is arranged on one side of the arc-shaped part one of the blocking piece. The recessed arc-shaped surface two is arranged on the other side of the arc-shaped part two of the blocking piece. The water flow on the water curtain plate one and the water curtain plate two is driven to move upwards along the arc surface of the arc-shaped part one and the arc-shaped part two due to the suction of the fan. The water flow moving along the arc surface will generate centrifugal force and hit the arc-shaped surface one along the arc-shaped part one. The water flow will form a tornado-like airflow between the arc-shaped part one and the arc-shaped surface one under the guidance of the arc-shaped part one and the arc-shaped surface one. When the water flow enters, the water flow will move towards the air outlet interval direction along the surface of the arc-shaped part one. Since the surface of the arc-shaped part one is arc-shaped, the water flow will generate centrifugal force and hit the arc-shaped surface one in the process of movement, and then slide along the arc-shaped surface one and hit the lower side of the arc-shaped part one. In this way, as the fan is turned on, a vortex-shaped water column will be formed between the arc-shaped part one and the arc-shaped surface one. Then, the dust entering will be repeatedly rotated and mixed by the vortex-shaped water column, so that the dust is fully mixed with water and separated from air. In this way, the purification efficiency of the dust in the air is greatly improved. The working principle of the arc-shaped part two and the arc-shaped surface two is the same as that of the arc-shaped part one and the arc-shaped surface one, and will not be described in detail here.

[0009] The inner side of the air duct is provided with a plurality of inclined blades along the circumference thereof, the blades shield the inner side of the air duct and have air gaps between two adjacent blades. A plurality of water droplets under the suction of the upper cavity air blower are also carried by the air to the top wall of the lower cavity, the water droplets hitting the top wall flow back to the bottom of the lower cavity along the side wall of the lower cavity, and some water droplets also flow into the air duct along the air flow, the water droplets entering the air duct are blocked by the blades arranged in the air duct, the blades shield the entire air duct, and then air gaps are arranged between the blades, when the water droplets hit the blades, the blades are wetted, after the water adheres to the blades, the air flow between the blades carries dust and further mixes with the water on the blades, since the blades are arranged in a fan shape and are fixedly connected to the inner side of the air duct, the air flow passing through the blades rotates in a spiral shape to generate centrifugal force, after the centrifugal force is generated, the water mixed with dust slides along the blades to the side wall of the air duct, and then falls back to the lower cavity along the side wall of the air duct, so that the purification efficiency of the purification device is further improved. The water curtain formed by the water flow on the water curtain plate is the first purification of dust; the vortex-shaped water column formed between the arc-shaped part one, the arc-shaped part two and the block is the second purification of dust; the blades in the air duct are arranged to be the third purification of dust, and the three can greatly absorb the air mixed with dust generated by polishing and grinding into the shell for purification, and the purification efficiency is high.

[0010] In the purification device of the four-station polishing machine, an outer ring pipe with the same diameter as the air duct is fixed to the inner side of the air duct, an inner ring pipe is arranged in the outer ring pipe and arranged on the same center line, the blades are uniformly distributed between the inner ring pipe and the outer ring pipe, and one end of the blades is fixed to the outer circumferential surface of the inner ring pipe, and the other end of the blades is fixed to the inner circumferential surface of the outer ring pipe.

[0011] An outer ring pipe with the same diameter as the air duct is fixed to the inner side of the air duct, an inner ring pipe is arranged in the outer ring pipe and arranged on the same center line, and the blades are uniformly distributed between the inner ring pipe and the outer ring pipe. The outer ring pipe and the inner ring pipe are fixed by the blades. The outer ring pipe, the blades and the inner ring pipe form a structure similar to a fan shape, and the blades are spirally distributed between the two, and the water droplets are left on the blades when passing through, and the air passes through the air gaps between the blades. When the air flow passes through the air duct, the spiral-shaped air gap makes the air flow out in a spiral shape, and the spiral-shaped air flow generates centrifugal force on the water droplets and the dust mixed in the water droplets and carries the mixed dust to the inner wall of the air duct. This design can separate the water droplets mixed in the air flow and discharge them, and the water droplets can fully contact the air flow and carry away the dust on the water droplets under the action of the centrifugal force during the movement of the water droplets to the inner wall of the air duct, thereby further improving the purification efficiency.

[0012] In the purification device of the four-station polishing machine, the air ducts between the upper cavity and the lower cavity are provided with two air ducts, the two air ducts are distributed along the length direction of the block, and each air duct is provided with a fan blade.

[0013] The two air ducts can increase the suction force of the lower cavity. Since the block is long strip-shaped, the single air duct cannot completely cover the block, the water curtain plate one and the water curtain plate two, and the two air ducts can cover a wider range. By increasing the air flow speed, the purification efficiency is further improved.

[0014] In the purification device of the four-station polishing machine, the top surface of the block is provided with a guide surface one and a guide surface two, and the guide surface one and the guide surface two are inclined towards the bottom of the block.

[0015] The intersection of the groove bottoms of the guide surface one and the guide surface two makes the upper end of the radial cross section of the block triangular. When the purification device is running, water droplets continuously drop from the inner circumferential surface of the air duct due to the water blocking of the fan blade. The water droplets are mostly mixed with dust. The water droplets falling on the top surface of the block can be quickly drained under the action of gravity, preventing the water droplets from entering the air duct again and causing secondary pollution, and further improving the purification efficiency.

[0016] In the purification device of the four-station polishing machine, the top ends of the water curtain plate one and the water curtain plate two are respectively provided with a water storage groove one and a water storage groove two, and the water storage groove one and the water storage groove two are located above the fan blade.

[0017] The lengths of the water storage groove one and the water storage groove two are the same as those of the water curtain plate one and the water curtain plate two. The water storage groove one and the water storage groove two can store water at the top ends of the water curtain plate one and the water curtain plate two. When the water in the water storage groove one and the water storage groove two overflows, the water can evenly overflow along the side walls to form a water curtain. The water storage groove one and the water storage groove two have two advantages. One is that the water curtain is more evenly distributed. The other is that the water droplets falling along the outer edge of the fan blade can fall into the water storage groove one and the water storage groove two. Since the fan blade is the third evolution, the amount of dust mixed in the water droplets is not much. Therefore, the water droplets can be recycled in the water storage groove one and the water storage groove two, greatly saving the water consumption of the purification device and saving water resources.

[0018] In the purification device of the four-station polishing machine, the water curtain plate one and the water curtain plate two are respectively connected with a baffle one and a baffle two above the water storage groove one and the water storage groove two. The baffle one is provided with a row of uniformly distributed water leakage holes one opposite the water storage groove one, and the baffle two is also provided with a row of uniformly distributed water leakage holes two opposite the water storage groove two.

[0019] The design of the baffle one and the baffle two can receive water droplets falling from the air duct opening in a wider range, and the water droplets slide into the water leakage hole one and the water leakage hole two along the upper end surface of the baffle one and the baffle two, and the water storage tank one and the water storage tank two are located below the water leakage hole one and the water leakage hole two, which further reduces the water consumption of the purification device and saves water resources.

[0020] In the purification device of the four-station polishing machine, the upper cavity is also connected with a drawer box with open upper and lower end surfaces, the drawer box is located in the upper cavity and can be pulled out, and the drawer box is provided with replaceable water absorption paper.

[0021] Since the fan is located at the top of the upper cavity, under the action of a large suction force, the fan blades in the air duct cannot completely block all water droplets or water mist in the air, and the fan is prone to damage due to long-term operation in a humid environment, the drawer box is provided below the fan, the drawer box has an open upper end and an open lower end, and the water absorption paper is placed in the drawer box, so that the water mist in the fan can be completely absorbed when the air flow passes through the water absorption paper, and the water absorption paper itself will become humid as the amount of absorbed water mist increases, which has the function of absorbing dust, and this design protects the fan and further enhances the purification efficiency of the purification device.

[0022] In the purification device of the four-station polishing machine, the drawer box has four and is provided opposite to each other and blocks the upper air inlet of the air duct.

[0023] The upper sides of each air duct are provided with a drawer box that can be pulled out, and the two oppositely arranged drawer boxes can block the upper sides of the air duct to a large extent, so that the air flow can pass through the water absorption paper in the drawer box to a large extent, which improves the purification efficiency to a certain extent.

[0024] Compared with the prior art, the product has the following advantages:

[0025] 1. The arc-shaped part one and the arc-shaped surface one form a vortex-shaped water column, and the dust entering the vortex-shaped water column is repeatedly rotated and mixed, so that it is fully mixed with water and separated from air, which greatly improves the purification efficiency of the dust in the air.

[0026] 2. The blades are arranged in a fan shape and fixedly connected with the inner side of the air duct, so that the air flow rotates spirally through the blades to generate centrifugal force, and the water mixed with dust slides along the blades to the side wall of the air duct after the centrifugal force is generated, and then falls to the lower cavity along the side wall of the air duct, which further improves the purification efficiency of the purification device.

[0027] 3、The water curtain formed by the water flow on the water curtain plate is the first purification of the dust; the vortex-shaped water column formed between the arc-shaped part one, the arc-shaped part two and the block is the second purification of the dust; the blade in the air duct is set to be the third purification of the dust, and the three can greatly purify the air mixed with dust generated by polishing and grinding into the shell, and the purification efficiency is higher.

DETAILED DESCRIPTION

[0035] The following is a specific embodiment of the present application and further describes the technical solution of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0036] Example one

[0037] As Figures 1-4The purification device of a four-station polishing machine shown in the figure comprises a housing 1 with an upper cavity 11 and a lower cavity 12, the upper cavity 11 is provided with a fan at the top, and a wind pipe 13 is arranged between the upper cavity 11 and the lower cavity 12 to connect the two cavities, the wind pipe 13 is a circular tubular structure. Two mutually symmetrical water curtain plates 2 and 3 are arranged below the wind pipe 13 in the lower cavity 12. The upper cavity 11 is an air extraction chamber for installing the fan, and the lower cavity 12 is a chamber for sucking dust, four air inlets are laterally arranged on the lower cavity 12, and grinding discs are arranged opposite the air inlets outside the housing 1, a motor is fixed between the two grinding discs on the same side, and the motor can drive the two grinding discs on one side to rotate. The grinding discs will rotate under the drive of the motor, and we can polish the workpiece on the grinding disc. The upper cavity 11 is communicated with the lower cavity 12 through the wind pipe 13, the wind pipe 13 has two parallel arrangements, and the arrangement of the two wind pipes 13 can increase the suction force of the lower cavity 12, and the design of the two wind pipes 13 can make the coverage range wider, and the air flow speed is increased. When the fan is turned on, the dust generated by the grinding disc can be sucked into the lower cavity 12. Two mutually symmetrical water curtain plates 2 and 3 are arranged below the wind pipe 13 in the lower cavity 12, and there is a continuous water curtain on the side of the water curtain plate 2 and the water curtain plate 3 opposite the air inlet, when the dust enters the lower cavity 12, it can directly contact the water curtain and mix with the water flow to be discharged with the water flow, thereby achieving the effect of purifying the air. The top ends of the water curtain plate 2 and the water curtain plate 3 are respectively provided with water storage tanks 22 and 32, the lengths of the water storage tanks 22 and 32 are the same as those of the water curtain plate 2 and the water curtain plate 3, and the water storage tanks 22 and 32 can store water at the top ends of the water curtain plate 2 and the water curtain plate 3. When the water in the water storage tanks 22 and 32 overflows, it can uniformly overflow along the side wall to form a water curtain. The arrangement of the water storage tanks 22 and 32 has two advantages, one of which is that the distribution of the formed water curtain is more uniform. The water curtain plate 2 and the water curtain plate 3 are respectively connected with baffle plates 8 and 9 above the water storage tanks 22 and 32, a row of uniformly distributed water leakage holes 81 are arranged on the baffle plate 8 opposite the water storage tank 22, and a row of uniformly distributed water leakage holes 91 are arranged on the baffle plate 9 opposite the water storage tank 32. The design of the baffle plates 8 and 9 can receive water droplets falling from the wind pipe 13 in a larger range, the water droplets slide into the water leakage holes 81 and 91 on the upper end surface of the baffle plates 8 and 9, and the water storage tanks 22 and 32 are respectively arranged below the water leakage holes 81 and 91, which further reduces the water consumption of the purification device and saves water resources.

[0038] The water curtain plate one 2 and the water curtain plate two 3 are respectively provided with arc-shaped part one 21 and arc-shaped part two 31 which are curved towards each other, the arc-shaped part one 21 and the arc-shaped part two 31 are provided with the block 4 which is in the shape of a long strip, the block 4 is provided with arc-shaped surface one 41 and arc-shaped surface two 42 which are concave inward on the two sides of the block 4 which are opposite to the arc-shaped part one 21 and the arc-shaped part two 31. The lower end of the arc-shaped part one 21 and the lower side of the arc-shaped surface one 41 form an air inlet interval, the upper end of the arc-shaped part one 21 and the upper side of the arc-shaped surface one 41 form an air outlet interval, the water flow from the water curtain plate one 2 will be brought into the arc-shaped part one 21 and the arc-shaped surface one 41 by the air flow, the water flow will move towards the air outlet interval along the surface of the arc-shaped part one 21 when it enters, the water flow will hit the arc-shaped surface one 41 due to the centrifugal force generated in the process of movement because the surface of the arc-shaped part one 21 is arc-shaped, the water flow will slide along the arc-shaped surface one 41 and then hit the side surface of the lower end of the arc-shaped part one 21. The water column in the shape of a vortex will be formed between the arc-shaped part one 21 and the arc-shaped surface one 41 when the fan is turned on, the dust will be repeatedly rotated and mixed by the water column in the shape of a vortex when it enters, so that it is fully mixed with water and separated from air, the setting greatly improves the purification efficiency of the dust in the air. The working principle of the arc-shaped part two 31 and the arc-shaped surface two 42 is the same as that of the arc-shaped part one 21 and the arc-shaped surface two 42, which will not be described in detail here.

[0039] As Figure 5 And Figure 6As shown, the wind pipe 13 is also fixed with a number of blades 5 distributed in a spiral shape, the blades 5 shield the wind pipe 13 and have wind gaps 51 between two adjacent blades 5. The blades 5 are fixed with the wind pipe 13 in the following way: an outer ring pipe 6 with the same diameter as the wind pipe 13 is fixed inside the wind pipe 13, an inner ring pipe 7 is arranged inside the outer ring pipe 6 and coaxial with the outer ring pipe 6, the blades 5 are uniformly distributed between the inner ring pipe 7 and the outer ring pipe 6, one end of each blade 5 is fixed on the outer circumferential surface of the inner ring pipe 7, and the other end of each blade 5 is fixed on the inner circumferential surface of the outer ring pipe 6. The outer ring pipe 6 and the inner ring pipe 7 are connected and fixed by the blades 5. Because of the suction of the fan, a number of water droplets will also be carried by the wind to the top wall of the lower cavity 12, the water droplets hitting the top wall will flow back to the bottom of the lower cavity 12 along the side wall of the lower cavity 12, and some water droplets will also enter the wind pipe 13 along the airflow, the water droplets entering the wind pipe 13 will be blocked by the blades 5 arranged in the wind pipe 13, the blades 5 will shield the entire wind pipe 13, and then wind gaps 51 are arranged between the blades 5, when the water droplets hit the blades 5, the blades 5 will be wet, after the water is attached to the blades 5, the airflow between the blades 5 will further mix with the water and the dust on the blades 5. Because the blades 5 are arranged in a spiral shape and are fixed, the airflow passing through the blades 5 will rotate in a spiral shape and generate centrifugal force, after the centrifugal force is generated, the water mixed with the dust will slide down the blades 5 to the side wall of the wind pipe 13, and then fall back to the lower cavity 12 along the side wall of the wind pipe 13. This design further improves the purification efficiency of the purification device. The outer ring pipe 6, the blades 5 and the inner ring pipe 7 form a structure similar to the shape of the blades 5, and the blades 5 are arranged in a spiral shape between the outer ring pipe 6 and the inner ring pipe 7. When the water droplets pass through, they will be left on the blades 5, and the wind will pass through the wind gaps 51 between the blades 5. When the airflow passes through the wind pipe 13, the wind gaps 51 will make the wind rotate in a spiral shape and be discharged. The spiral airflow will generate centrifugal force on the water on the blades 5, which will carry the mixed dust and hit the inner wall of the wind pipe 13. This design can separate the water mixed in the airflow and discharge it, and at the same time, the water can fully contact the airflow and carry away the dust on it during the movement to the inner wall of the wind pipe 13, further improving the purification efficiency.

[0040] As shown in the drawings, Figures 1-6 The water flow on the water curtain plate is the first purification of dust; the arc part one 21, the arc part two 31 and the block 4 are the second purification of dust; the blades 5 in the wind pipe 13 are the third purification of dust, and the combination of the three can greatly purify the air mixed with dust generated by polishing and grinding into the shell 1, and the purification efficiency is high.

[0041] The water storage tank 22 and the water storage tank 32 are located opposite the outer edge of the blade 5, and the water droplets falling along the outer edge of the blade 5 can fall into the water storage tank 22 and the water storage tank 32. Since the blade 5 is the third evolution, the amount of dust mixed in the water droplets is small, so the water droplets can re-enter the water storage tank 22 and the water storage tank 32 for recycling, greatly saving the consumption of water by the purification device and saving water resources. Two air ducts 13 are distributed along the length direction of the block 4, and each air duct 13 is provided with a blade 5. The top surface of the block 4 is provided with a guide surface 43 and a guide surface 44, and the groove bottoms of the guide surface 43 and the guide surface 44 intersect to form a triangular shape at the upper end of the radial cross section of the block 4. Since the block 4 is located directly below the air duct 13, when the purification device is running, water droplets will continuously drip from the inner circumferential surface of the air duct 13 due to the water blocking of the blade 5. The dripping water droplets are mostly mixed with dust, and the dripping water droplets will fall on the top surface of the block 4. The triangular top surface design allows the dripping water droplets to quickly drain under the action of their own gravity, preventing them from entering the air duct 13 again and causing secondary pollution, thereby further increasing the purification efficiency.

[0042] The upper chamber 11 is also connected to a drawer box 10 which is open at both the upper and lower ends. The drawer box 10 is located in the upper chamber 11 and can be pulled out. The drawer box 10 is provided with replaceable water-absorbing paper. The drawer box 10 has four, with two on each side of the upper chamber 11 corresponding to each air duct 13. The two drawer boxes 10 are arranged opposite each other and block the upper air inlet of the air duct 13. Since the fan is located at the top of the upper chamber 11, under the action of a large suction force, the blade 5 in the air duct 13 cannot completely block all water droplets or water mist in the air. The fan is prone to damage when operating in a humid environment for a long time. The purification device is designed to have a drawer box 10 that can be pulled out below the fan. The drawer box 10 is open at both the upper and lower ends, and water-absorbing paper is placed inside. When the air flow passes through the water-absorbing paper, the water mist inside can be completely absorbed. As the amount of absorbed water mist increases, the water-absorbing paper itself becomes damp and has the function of absorbing dust. This design not only protects the fan but also further enhances the purification efficiency of the purification device. Each air duct 13 is provided with a drawer box 10 that can be pulled out at the top of both sides. The two oppositely arranged drawer boxes 10 can block the top of the air duct 13 to the greatest extent, allowing the air flow to pass through the water-absorbing paper in the drawer box 10 to the greatest extent, thereby improving the purification efficiency. The water-absorbing paper can be replaced by pulling out the drawer box 10, which is relatively convenient.

[0043] Example Two

[0044] The embodiment is basically same as the structure and principle of the embodiment one, and the difference is that the fan blade 5 end directly and the air pipe 13 are fixed by welding in the embodiment, which can achieve the same technical effect.

[0045] The specific embodiments described herein are merely illustrative of the spirit of the present application. Those skilled in the art can make various modifications or supplements to the specific embodiments described or replace them with similar ways, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.
