Description

Technical Field

[0001] The invention relates to the technical field of casting processing, in particular to a dust reduction and recovery polishing table for irregular castings. Background Art

[0002] Grinding tables are widely used in metal processing, woodworking, ceramics, plastics and other industries. They use high-speed rotating tools to grind the surface of materials, generating a large amount of dust. Existing equipment generally uses water mist to reduce dust explosions and the harm of dust explosions to the human body caused by its spread into the air.

[0003] After the existing equipment uses water mist to reduce dust, the polished scraps will accumulate on the polishing table. It is troublesome to recycle a large amount of residual materials and the remaining material powder. The existing equipment generally uses sieve plates for filtration or filter tanks for sedimentation treatment. During the long processing process, blockage is inevitable. The operator needs to clean the filter mechanism to reduce the blockage and accumulation of sewage. The metal chips generated also need to be cleaned and recycled regularly by the operator. Otherwise, oil or metal oxides (such as rust mud) adhered after being wetted are easy to adhere to the pipe wall, which will cause the entire filtration and recovery system to be blocked, resulting in time-consuming cleaning and increased labor costs. For this reason, we propose a dust reduction and recovery polishing table for irregular castings to solve the above problems. Summary of the Invention

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-Figure 7 The present invention provides a technical solution: a dust reduction and recovery polishing table for irregular castings, comprising:

[0036] The polishing table body 1 is provided with a set of transmission troughs 12 inside, a flow guide mechanism 4 is provided inside the transmission trough 12, a separation screen plate 3 is provided on the top of the transmission trough 12, and a plurality of separation slots are provided on the separation screen plate 3. The polishing table body 1 is provided with a liquid inlet trough with a movably inserted suspension shaft 2, and both sides of the suspension shaft 2 are against the edges of the separation screen plate 3;

[0037] Among them, the guide mechanism 4 includes a fixed baffle 41 and a conveying trough 42. The fixed baffle 41 is clamped inside the transmission trough 12. The conveying trough 42 is installed on the top of the fixed baffle 41 and has reset pads 43 on both sides for supporting the separation screen plate 3. The guide mechanism 4 is used to discharge the separated sewage. When it is necessary to deal with the dust in the grinding process, the dust and metal chips can be reduced with the help of water mist, and the dust suction mechanism can also start to run, and a small part of the dust is negatively adsorbed, which can reduce the flying of dust. When the water mist encounters metal chips or dust sedimentation, it can be gathered in the grinding table body 1 into sewage, which is separated and discharged with the help of the separation screen plate 3 and the guide mechanism 4. Metal chips can be collected, which is convenient for unified processing and recycling during subsequent cleaning.

[0038] like Figure 2 As shown, in order to reduce the situation where sewage accumulates and causes blockage and needs to be cleaned during dust reduction, a plurality of snap-in mesh plates 33 are provided inside the separation screen plate 3. The snap-in mesh plates 33 are fixed at the bottom of the separation tank and the position corresponds to the conveying tank 42. The snap-in mesh plates 33 and the separation tank form a screening cavity, which can separate metal particles and the like in the sewage and introduce them into the diversion mechanism 4. The snap-in mesh plates 33 can separate and intercept small particles of metal debris and the like in the sewage, reducing their entry into the subsequent diversion mechanism 4.

[0039] The snap-fit ​​mesh plate 33 is elastic, and an elastic skeleton is provided inside the separation screen plate 3, which can be supported inside the grinding table body 1. The elasticity of the separation screen plate 3 itself can produce a small deformation when the casting and the operator apply pressure to grind the casting, which can drive the separation screen plate 3 and the internal snap-fit ​​mesh plate 33 to move slightly, which can further improve the separation efficiency of sewage and reduce blockage.

[0040] like Figure 2 As shown, in order to reduce the overflow of sewage due to blockage, a plurality of reset rods 31 are inserted into the side of the separation screen plate 3 close to the suspension shaft 2. The position of the reset rod 31 corresponds to the separation tank, and a plurality of transmission separation shafts 32 are rotatably provided inside the separation tank. An elastic band is provided at one end of the reset rod 31 and is evenly wrapped around the edge of the transmission separation shaft 32. The movement of the reset rod 31 can be used as a drive to pull the transmission separation shaft 32 to move. One end of the reset rod 31 is in contact with the edge of the suspension shaft 2. When the clamping mesh plate 33 is blocked by metal chips accumulation, the sewage level inside gradually rises, and the suspension shaft 2 can be driven to move upward under the action of buoyancy, so that the side wall of the suspension shaft 2 can be in contact with the reset rod 31, pushing the reset rod 31 to move, thereby driving the transmission separation shaft 32 to move with the help of the stretching shaft;

[0041] A pair of extension plates are provided on the surface of the transmission separation shaft 32, and the extension plates can stir and separate the metal chips entering the separation tank, thereby accelerating the diversion and separation of sewage. As the transmission separation shaft 32 pulls the elastic belt to control its movement during the movement of the reset plug rod 31, it can stir the metal chips accumulated on the top of the clamping mesh plate 33, thereby accelerating the discharge of sewage and reducing the accidental situation of debris blocking sewage overflow.

[0042] like Figure 4 As shown, a plurality of semicircular grooves are provided on the top of the suspension shaft 2, and an adsorption sheet is provided inside the semicircular groove which is arranged perpendicularly thereto, for adsorbing impurities floating on the top of the sewage, which can play an auxiliary cleaning role and reduce the situation where suspended matter is adsorbed on the inner wall of the grinding table body 1 along with the sewage.

[0043] like Figure 5 As shown, in order to smoothly discharge the sewage, a clamping plate 421 is clamped on the fixed baffle 41, and the conveying trough 42 is clamped on the top of the clamping plate 421. A plurality of transmission holes are opened on the clamping plate 421 and the fixed baffle 41. A plurality of conveying rings 44 are installed on the clamping plate 421. The conveying rings 44 are evenly distributed on both sides of the conveying trough 42 and are connected with the transmission holes. The sewage can be discharged along the conveying trough 42;

[0044] A plurality of diversion grooves 422 corresponding to the conveying ring 44 are provided inside the conveying groove 42 . The sewage is dispersed and discharged under the action of the diversion grooves 422 and can be discharged along the movable inserting tube 13 and the guide tube 14 .

[0045] like Figure 7As shown, in order to reduce blockage during the subsequent sewage transmission process, a separation pad 471 is provided at the bottom of the inner wall of the conveying ring 44. The separation pad 471 is an elastic mesh plate, and a snap-in ball 47 is provided on the upper end of the elastic mesh plate. The snap-in ball 47 is clamped at the bottom of the reset pad 43. A plurality of stretching shafts are connected between the snap-in ball 47 and the separation pad 471, and a plurality of rubber rings are provided on the surface of the stretching shaft. During the movement of the reset pad 43, the snap-in ball 47 can be driven to move, thereby pulling the stretching shaft to move, and can move during the operator's grinding of the casting, and a small amount of metal chips can also be absorbed in the gap of the rubber ring to reduce internal blockage.

[0046] like Figure 6 As shown, a positioning baffle 431 is provided at one end of the reset pad 43, and the positioning baffle 431 is horizontally arranged and abuts against the bottom of the separation screen plate 3;

[0047] A separation plate 45 is installed on the inclined surface of the reset pad 43. The separation plate 45 is made of multiple layers of nylon mesh and is used for sewage diversion and separation. A plurality of transmission pressure rods 451 are installed on the top of the separation plate 45. A plurality of screening shafts 46 are provided inside the conveying trough 42, which are fixed inside the diversion trough 422. The screening shafts 46 are against one side of the transmission pressure rod 451. When the sewage flows along the inclined reset pad 43, the fine dirt and debris remaining in the sewage can be left on the separation plate 45, and the impurities can be removed for a second time. Interception can reduce the accumulation of dirt in the subsequent transmission pipeline, which can reduce the blockage of the transmission pipeline and extend the cleaning and maintenance cycle of the filtering equipment. In the grinding process, the operator can continuously adjust the position angle of the casting, so that the separation screen plate 3 and the reset pad 43 are deformed by force, which can drive the separation plate 45 on the top of the reset pad 43 to move, and can make the transmission pressure rod 451 move with the separation plate 45 to squeeze the screening shaft 46, reduce the blockage here, and ensure the smooth discharge of subsequent sewage.

[0048] like Figure 1 As shown, a dust suction mechanism is installed on the inner side of the grinding table body 1, and a recovery mesh plate 11 is provided on the dust suction mechanism to reduce the spread of dust, water mist, etc.

[0049] like Figure 3 and Figure 4 As shown, a plurality of movable insert tubes 13 are inserted at the bottom of the grinding table body 1, a plurality of guide grooves are provided on the surface of the movable insert tube 13 and are connected with the delivery hole, and a guide tube 14 that is connected to each other is connected to the outside of the movable insert tube 13, and the guide tube 14 is connected to the external transmission pump, and can discharge the sewage with the help of the external transmission pump.

[0050] Working principle: First, when it is necessary to deal with dust during the grinding process, water mist can be used to reduce dust and metal chips, and the dust suction mechanism can also start to operate, and a small part of the dust is adsorbed under negative pressure, which can reduce the flying of dust. When the water mist encounters metal chips or dust settling, it can be gathered into sewage inside the grinding table main body 1, and separated and discharged with the help of the separation screen plate 3 and the guide mechanism 4, so that the metal chips can be collected and convenient for unified treatment and recycling during subsequent cleaning. As the sewage gathers inside the grinding table main body 1, when a single casting is ground for a long time, metal chips are prone to accumulate on the clamping mesh plate 33, causing blockage. As the sewage level rises, it can drive the suspension shaft 2 to move upward under the action of buoyancy, so that the side wall of the suspension shaft 2 can be against the reset plug rod 31, pushing the reset plug rod 31 to move, thereby driving the transmission separation shaft 32 to move with the help of the stretching shaft, and the surface of the clamping mesh plate 33 can be cleaned with the help of the extension plate, so that the sewage can be quickly discharged, reducing blockage.

[0051] Then, during the sewage conduction process, it can enter the inside of the guide mechanism 4 along the snap-on mesh plate 33, and when the sewage flows along the inclined reset pad 43, the fine dirt and debris remaining in the sewage can be retained on the separation plate 45, which can intercept impurities for a second time, reduce the accumulation of dirt in the subsequent transmission pipeline, reduce the blockage of the transmission pipeline, and extend the cleaning and maintenance cycle of the filtering equipment. In addition, during the grinding process, the operator can continuously adjust the position angle of the casting, so that the separation screen plate 3 and the reset pad 43 are deformed by force, which can drive the separation plate 45 on the top of the reset pad 43 to move, and can make the transmission pressure rod 451 move with the separation plate 45 to squeeze the screening shaft 46, thereby reducing the blockage here and ensuring the smooth discharge of subsequent sewage.

[0052] Finally, during the movement of the reset pad 43, the receiving ball 47 can be driven to move, thereby pulling the stretching shaft to move. It can move during the operator's grinding of the casting, reducing internal blockage and discharging sewage along the movable insert 13 and the guide pipe 14.

[0053] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
