Description

Technical Field

[0001] This invention relates to the field of casting processing technology, specifically to a dust-recovery grinding table for irregular castings. Background Technology

[0002] Grinding tables are widely used in industries such as metal processing, woodworking, ceramics, and plastics. They grind the surface of materials by rotating tools at high speed, generating a large amount of dust. Existing equipment generally uses water mist and other methods to suppress dust, thereby reducing the risk of dust explosions and its spread into the air to the human body.

[0003] Existing equipment, after dust suppression using water mist, accumulates grinding scraps on the grinding table, making the recycling and reuse of large amounts of leftover material and powder quite troublesome. Current equipment typically uses sieve plates for filtration or sedimentation in filter tanks, but clogging is inevitable during prolonged processing. Operators need to clean the filtration system to reduce wastewater buildup, and the generated metal shavings also require regular cleaning and recycling. Otherwise, oil stains or wetted metal oxides (such as rust sludge) can easily adhere to the pipe walls, causing blockages in the entire filtration and recycling system, resulting in time-consuming cleaning and increased labor costs. Therefore, we propose a dust suppression and recycling grinding table for irregular castings to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to provide a dust-recovery grinding table for irregular castings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a dust-recovery grinding table for irregular castings, comprising,

[0006] The grinding table body has a set of transmission channels inside, the transmission channels are equipped with a flow guiding mechanism, the top of the transmission channels is equipped with a separation sieve plate, the separation sieve plate is provided with multiple separation channels, and the grinding table body is provided with a liquid inlet channel in which a suspension shaft is movably inserted, the two sides of the suspension shaft abutting against the edge of the separation sieve plate;

[0007] The flow guiding mechanism includes a fixed baffle and a conveying trough. The fixed baffle is installed inside the conveying trough, and the conveying trough is installed on the top of the fixed baffle and has reset pads on both sides for supporting the separation screen plate. The flow guiding mechanism is used to discharge the separated wastewater. When it is necessary to treat the dust during the grinding process, water mist can be used to suppress dust and metal shavings. The dust collection mechanism can also start to operate, using negative pressure to adsorb a small portion of the dust, which can reduce the dust from flying. When the water mist encounters metal shavings or dust and causes them to settle, it can gather into wastewater inside the grinding table body. The wastewater is then separated and discharged with the help of the separation screen plate and the flow guiding mechanism. Metal shavings can be collected for unified treatment and recycling during subsequent cleaning.

[0008] Preferably, the separating screen plate is equipped with multiple snap-fit ​​mesh plates inside. The snap-fit ​​mesh plates are snapped at the bottom of the separating tank and their positions correspond to the conveying tank. The snap-fit ​​mesh plates and the separating tank form a screening chamber, which can separate metal particles and other materials in the sewage and guide them into the guiding mechanism.

[0009] The snap-fit ​​screen plate is elastic, and the separation screen plate has an elastic skeleton inside, which can support it inside the grinding table body. The elastic skeleton of the separation screen plate and the reset pad adopt a deformation adaptive design, which generates flexible buffer when the casting is ground and pressured. This not only avoids wear of rigid structure, but also drives the transmission pressure rod to squeeze the screening shaft through deformation, dynamically maintaining filtration efficiency and enhancing the stability and service life of the equipment in frequent operation.

[0010] Preferably, a plurality of reset rods are inserted into the side of the separation screen plate near the suspension shaft. The position of the reset rods corresponds to the separation groove, and a plurality of transmission separation shafts are rotatably arranged inside the separation groove. One end of the reset rod is provided with an elastic band that is evenly wrapped around the edge of the transmission separation shaft. The movement of the reset rod can drive the transmission separation shaft to move. One end of the reset rod abuts against the edge of the suspension shaft.

[0011] The transmission separation shaft is equipped with a pair of extension plates on its surface. These extension plates can agitate and separate metal shavings entering the separation tank, accelerating the separation of wastewater. Through the linkage design of the elastic snap-fit ​​mesh plate and the floating suspension shaft, the suspension shaft is triggered to push the reset rod when the liquid level rises, which drives the transmission separation shaft to agitate the metal shavings and prevent the screen holes from clogging. The elastic skeleton of the separation screen plate and the deformation of the reset pad drive the movement of the screening shaft, further clearing the diversion path and achieving self-cleaning during equipment operation, reducing manual intervention.

[0012] Preferably, the top of the suspension shaft is provided with multiple semi-circular grooves, and the interior of the semi-circular grooves is provided with adsorption plates arranged perpendicular to it, which are used to adsorb impurities floating on the top of the sewage, thereby enhancing the adsorption effect on suspended impurities.

[0013] Preferably, a snap-fit ​​plate is clamped on the fixed baffle, the conveying groove is clamped on the top of the snap-fit ​​plate, and multiple transmission holes are opened on both the snap-fit ​​plate and the fixed baffle. Multiple conveying rings are installed on the snap-fit ​​plate, and the conveying rings are evenly distributed on both sides of the conveying groove and communicate with the transmission holes.

[0014] The conveying trough is equipped with multiple diversion troughs corresponding to the conveying ring.

[0015] Preferably, the bottom of the inner wall of the conveying ring is provided with a separation pad, the separation pad is an elastic mesh plate, and the upper end of the elastic mesh plate is provided with a snap-fit ​​ball, the snap-fit ​​ball is snapped into the bottom of the reset pad, and multiple tension shafts are connected between the snap-fit ​​ball and the separation pad, and multiple rubber rings are provided on the surface of the tension shafts.

[0016] Preferably, one end of the reset pad is provided with a positioning baffle, which is horizontally positioned and abuts against the bottom of the separating sieve plate;

[0017] A separation plate is installed on the inclined surface of the reset pad. The separation plate is made of multiple layers of nylon mesh and is used for sewage diversion and separation. Multiple transmission pressure rods are installed on the top of the separation plate. Multiple screening shafts are installed inside the conveying trough and are locked inside the diversion trough. The screening shafts abut against one side of the transmission pressure rods. Fine dirt is adsorbed by the multiple layers of nylon separation plate on the inclined reset pad.

[0018] Preferably, a dust collection mechanism is installed on the inner side of the grinding table body, and a recycling mesh plate is provided on the dust collection mechanism.

[0019] Preferably, the bottom of the grinding table body is provided with multiple movable tubes, the surface of the movable tubes is provided with multiple guide grooves and communicates with the conveying holes, the outside of the movable tubes is connected to mutually communicating guide pipes, and the guide pipes are connected to an external transfer pump.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention uses a linkage design between an elastic snap-fit ​​screen plate and a floating suspension shaft. When the liquid level rises, the suspension shaft is triggered to push the reset rod, which drives the transmission separation shaft to stir up metal chips and prevent the screen holes from clogging. The elastic skeleton of the separation screen plate and the deformation of the reset pad drive the screen shaft to move, further clearing the diversion path and achieving self-cleaning during equipment operation, reducing manual intervention.

[0022] 2. This invention uses a snap-fit ​​mesh plate inside the separation tank to intercept large metal shavings, and a multi-layer nylon separation plate on the tilting reset pad to adsorb fine dirt. Combined with the elastic mesh plate and rubber ring inside the conveying ring to adsorb micro dust, a three-stage filtration system is formed, which can extend the maintenance cycle of the filtration components.

[0023] 3. The present invention adopts a deformation adaptive design by separating the elastic skeleton of the screen plate and the reset pad plate, which generates flexible buffer when the casting is ground and subjected to pressure. This not only avoids wear of the rigid structure, but also dynamically maintains the filtration efficiency by squeezing the screen shaft through the deformation-driven transmission pressure rod, thereby enhancing the stability and service life of the equipment in frequent operation.

[0024] 4. The present invention adopts modular assembly of snap-fit ​​mesh plate, conveying groove and movable insertion tube, and with positioning baffle and snap-fit ​​plate quick disassembly structure, it is convenient to clean metal debris and replace filter components.

[0025] 5. This invention significantly suppresses the spread of dust and metal shavings during the grinding process through the synergistic effect of water mist dust suppression and dust collection mechanism, thus improving the working environment; the multi-stage filtration system of separation screen plate, snap-fit ​​mesh plate and flow guiding mechanism realizes efficient separation of sewage and metal particles, enabling the centralized recycling of metal shavings, reducing resource waste and lowering subsequent treatment costs.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Please see Figures 1-7 This invention provides a technical solution: a dust-recovery grinding table for irregular castings, comprising,

[0036] The grinding table body 1 has a set of transmission channels 12 inside, a flow guiding mechanism 4 inside the transmission channels 12, a separation sieve plate 3 on the top of the transmission channels 12, a plurality of separation channels on the separation sieve plate 3, and a liquid inlet channel on the grinding table body 1 in which a suspension shaft 2 is movably inserted, with the sides of the suspension shaft 2 abutting against the edges of the separation sieve plate 3.

[0037] The flow guiding mechanism 4 includes a fixed baffle 41 and a conveying trough 42. The fixed baffle 41 is installed inside the conveying trough 12, and 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 flow guiding mechanism 4 is used to discharge the separated wastewater. When it is necessary to treat the dust in the grinding process, it can use water mist to reduce dust and metal shavings. The dust collection mechanism can also start to operate, and a small part of the dust can be adsorbed by negative pressure to reduce the dust flying. When the water mist encounters metal shavings or dust and settles, it can gather into wastewater inside the grinding table body 1. It can be separated and discharged with the help of the separation screen plate 3 and the flow guiding mechanism 4, and the metal shavings can be collected for unified treatment and recycling during subsequent cleaning.

[0038] like Figure 2 As shown, in order to reduce the need for cleaning due to sewage accumulation during dust suppression, multiple snap-fit ​​mesh plates 33 are installed inside the separation screen plate 3. The snap-fit ​​mesh plates 33 are snapped at the bottom of the separation tank and their positions correspond to the conveying tank 42. The snap-fit ​​mesh plates 33 and the separation tank form a screening chamber, which can separate metal particles in the sewage and guide them into the guiding mechanism 4. The snap-fit ​​mesh plates 33 can separate and retain small metal fragments in the sewage, reducing their entry into the subsequent guiding mechanism 4.

[0039] The snap-fit ​​screen plate 33 is elastic, and the separation screen plate 3 has an elastic skeleton inside, which can support it 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 ​​screen plate 33 to make a small movement, which can further improve the separation efficiency of sewage and reduce clogging.

[0040] like Figure 2 As shown, in order to reduce the overflow of sewage due to blockage, multiple reset rods 31 are inserted on the side of the separation screen plate 3 near the suspension shaft 2. The position of the reset rods 31 corresponds to the separation tank, and multiple transmission separation shafts 32 are rotatably installed inside the separation tank. One end of the reset rod 31 is provided with an elastic band and is evenly wrapped around the edge of the transmission separation shaft 32. The movement of the reset rod 31 can drive the transmission separation shaft 32 to move. One end of the reset rod 31 abuts against the edge of the suspension shaft 2. When metal shavings accumulate on the snap-fit ​​screen plate 33 and cause blockage, the sewage level inside gradually rises. Under the action of buoyancy, the suspension shaft 2 can be driven to move upward, so that the side wall of the suspension shaft 2 abuts against 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 tension shaft.

[0041] The transmission separation shaft 32 is provided with a pair of extension plates on its surface. The extension plates can agitate and separate the metal shavings that enter the separation tank, thereby accelerating the separation of sewage. As the transmission separation shaft 32 pulls the elastic band to control its movement during the movement of the reset rod 31, it can agitate the metal shavings accumulated on the top of the snap-fit ​​mesh plate 33, thereby accelerating the discharge of sewage and reducing the possibility of debris clogging sewage overflow.

[0042] like Figure 4 As shown, the top of the suspension shaft 2 has multiple semi-circular grooves, and the inside of the semi-circular grooves is equipped with adsorption plates that are perpendicular to it, which are used to adsorb 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 sewage, a snap-fit ​​plate 421 is snapped on the fixed baffle 41, and the conveying trough 42 is snapped on the top of the snap-fit ​​plate 421. Both the snap-fit ​​plate 421 and the fixed baffle 41 are provided with multiple transmission holes. Multiple conveying rings 44 are installed on the snap-fit ​​plate 421. The conveying rings 44 are evenly distributed on both sides of the conveying trough 42 and are connected to the transmission holes, so that sewage can be discharged along the conveying trough 42.

[0044] The conveying trough 42 is equipped with multiple diversion troughs 422 corresponding to the conveying ring 44. Under the action of the diversion troughs 422, the sewage is dispersed and discharged, and can be discharged along the movable insertion tube 13 and the guide tube 14.

[0045] like Figure 7As shown, in order to reduce the possibility of blockage during subsequent sewage transmission, 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-fit ​​ball 47 is provided at the upper end of the elastic mesh plate. The snap-fit ​​ball 47 is snapped at the bottom of the reset pad 43. Multiple tension shafts are connected between the snap-fit ​​ball 47 and the separation pad 471, and multiple rubber rings are provided on the surface of the tension shafts. During the movement of the reset pad 43, the snap-fit ​​ball 47 can be moved, thereby pulling the tension shafts. This allows the pads to move during the grinding process of the castings by the operator, and the gaps between the rubber rings can also absorb a small amount of metal shavings, reducing the possibility of internal blockage.

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

[0047] A separation plate 45 is mounted 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. Multiple transmission pressure rods 451 are mounted on the top of the separation plate 45. Multiple screening shafts 46 are installed inside the conveying trough 42 and are locked inside the diversion trough 422. The screening shafts 46 abut against one side of the transmission pressure rods 451. When sewage flows along the inclined reset pad 43, it can leave fine dirt and debris in the sewage on the separation plate 45, which can perform secondary separation of impurities. By intercepting and reducing the accumulation of dirt in the subsequent transmission pipeline, the filtration equipment can be cleaned and maintained more frequently. During the grinding process, the operator can continuously adjust the position and angle of the casting, which causes the separation screen plate 3 and the reset pad plate 43 to deform under stress. This causes the separation plate 45 on top of the reset pad plate 43 to move, and the transmission pressure rod 451 to follow the movement of the separation plate 45, which in turn squeezes the screening shaft 46, reducing the possibility of blockage and ensuring smooth discharge of subsequent wastewater.

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

[0049] like Figure 3 and Figure 4 As shown, multiple movable tubes 13 are inserted into the bottom of the grinding table body 1. Multiple guide grooves are provided on the surface of the movable tubes 13 and are connected to the conveying holes. The outer side of the movable tubes 13 is connected to the interconnected guide pipes 14. The guide pipes 14 are connected to the external transfer pump, which can help to discharge sewage.

[0050] Working principle: First, when dust needs to be treated during the grinding process, water mist can be used to suppress dust and metal shavings, and the dust collection mechanism can also start to operate, adsorbing a small amount of dust under negative pressure, which can reduce dust flying. When the water mist encounters metal shavings or dust and causes them to settle, it can collect inside the grinding table body 1 as wastewater, which is separated and discharged by the separation screen plate 3 and the guide mechanism 4. It can collect metal shavings, which are convenient for unified treatment and recycling during subsequent cleaning. As the wastewater collects inside the grinding table body 1, when grinding a single casting for a long time, metal shavings can easily accumulate on the snap-fit ​​screen plate 33, causing blockage. As the wastewater level rises, under the action of buoyancy, it can drive the suspension shaft 2 to move upward, so that the side wall of the suspension shaft 2 can abut against the reset rod 31, pushing the reset rod 31 to move, which in turn drives the transmission separation shaft 32 to move through the tension shaft. The extension plate can clean the surface of the snap-fit ​​screen plate 33, thereby quickly discharging the wastewater and reducing blockage.

[0051] Then, during the sewage transfer process, the sewage can enter the flow guiding mechanism 4 through the snap-fit ​​screen plate 33. When the sewage flows along the inclined reset pad plate 43, it can leave the fine dirt and debris in the sewage on the separation plate 45, which can perform secondary interception of impurities, 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 filtration equipment. During the grinding process, the operator can continuously adjust the position and angle of the casting, which can cause the separation screen plate 3 and the reset pad plate 43 to deform under force, which can drive the separation plate 45 on the top of the reset pad plate 43 to move. This allows the transmission pressure rod 451 to follow the movement of the separation plate 45, squeezing the screening shaft 46, reducing the possibility of blockage at this point, and ensuring the smooth discharge of subsequent sewage.

[0052] Finally, during the movement of the reset pad 43, it can drive the snap ball 47 to move, thereby pulling the tension shaft to move. It can move during the grinding process of the casting by the operator, reducing internal blockage, and can discharge sewage along the movable insertion tube 13 and the guide tube 14.

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