Description

Technical Field

[0001] The invention relates to the technical field of particle separation, and in particular to a gas spraying particle tail gas treatment device. Background Art

[0002] Parts powder spraying is a surface treatment technology that forms a solid surface coating by spraying powder particles onto the surface of the parts and then curing them by heating. Metal parts in architectural decoration projects often need to be powder sprayed. In the powder spraying workshop, the air often contains a large amount of powder particles, which have a high recycling value. In addition, the exhaust containing powder particles is difficult to meet the emission standards. If it is directly inhaled by the human body, it will also cause harm to the human body. Therefore, a device is needed to separate the powder particles from the exhaust gas before discharging the exhaust gas.

[0003] For example, the Chinese patent document entitled "A filter element type after-filter for powder spraying equipment" with the authorization announcement number CN217829297U connects the air inlet pipe to the exhaust pipe of the powder spraying equipment, continuously draws air containing powder from the air inlet pipe, and the filter plate filters out the powder in the air, and the filtered air is discharged from the air outlet pipe. During the operation of the filter, that is, during the process of filtering the air containing powder, the vibration motor drives the mounting frame to vibrate, and the mounting frame drives the filter plate to vibrate, thereby removing the powder attached to the filter plate and causing the powder to fall into the collection box. After the filter plate stops operating, remove the bolts, open the box door, take out the collection box, and process the powder in the collection box.

[0004] In view of the above-mentioned related technologies, when the operator takes out the collection box and processes the powder particles in the collection box, the filter plate needs to stop working, otherwise the filtered powder particles will be directly dispersed into the external air through the box door, causing secondary pollution to the air and reducing the efficiency of separating the powder particles from the exhaust gas. In addition, the vibration of the filter plate increases the circulation rate of the air in the collection box, causing the powder particles deposited in the collection box to be raised again, which is not conducive to the collection of the powder particles in the collection box. Summary of the invention

[0005] In view of this, the present invention provides a gas spraying particle exhaust treatment device, which aims to solve the problem that the motor needs to be shut down to stop separating the powder particles from the exhaust gas, and the filter plate vibration increases the air circulation rate in the collection box, causing the powder particles deposited in the collection box to be lifted up again.

[0006] In order to solve the problem that the motor needs to be shut down to stop the powder spraying work on the surface of the part, thereby reducing the efficiency of the powder spraying processing on the surface of the part, the present invention provides a gas spraying particle exhaust gas treatment device, comprising a box body; a plurality of filter screens, which are arranged in the box body, and a plurality of spare screens are arranged outside the box body, and the number of the spare screens is equal to the filter screen; a rotating source is fixedly installed in the box body, and the number of the rotating source is equal to the filter screen, and a driving shaft of the rotating source is fixedly sleeved with a driving gear, and the driving shaft of the rotating source is fixedly connected with a transmission screw, and the transmission screw is threadedly connected with a transmission block, and the two side walls facing the transmission block are abutted with fixed limit rods, and the top wall of the transmission block is fixedly connected with a transmission spring, and the transmission spring is abutted with a conversion plate at one end away from the transmission block, one of the filter screens and one of the spare screens are respectively fixedly arranged at two ends of the conversion plate, and the top wall of the conversion plate is fixedly connected with a conversion gear that can mesh with the driving gear.

[0007] By adopting the above technical solution, the transmission screw rotates to drive the spare net to move vertically into the box, and the transmission screw drives the filter net and the spare net to rotate, exchanging the positions of the filter net and the spare net. When one of the filters is replaced, the remaining filter net in the spraying area continues to filter dust, omitting the step of shaking the filter net to remove dust, realizing the function of replacing the filter net without stopping the machine, and improving the efficiency of separating powder particles from exhaust gas.

[0010] By adopting the above technical solution, the partition can reduce the number of powder particles in the spraying area entering the replacement area, and reduce the probability of parts in the replacement area being damaged by powder particles.

[0031] To make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the following will be combined with the appended drawings of the embodiments of the present invention. Figure 1-Figure 7 , the technical scheme of the embodiment of the present invention is clearly and completely described. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments. Based on the described embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the present invention.

[0032] This embodiment provides a gas spraying particle tail gas treatment device, referring to Figure 1 A gas spraying particle exhaust treatment device includes a box body 1, and a partition 11 is horizontally fixedly connected to the inner wall of the box body 1. Below the partition 11 is a spraying area 12. The parts to be processed are located in the spraying area 12, and the operator sprays the powder particles on the surface of the parts. Above the partition 11 is a replacement area 13. The partition 11 is provided with a plurality of through holes 111. The spraying area 12 and the replacement area 13 are connected through the through holes 111. A filter screen 2 for filtering dust is arranged in the spraying area 12. The number of the filter screens 2 is equal to the number of the through holes 111. The top wall of the filter screen 2 is rotatably connected to a first ventilation pipe 21. Both the filter screen 2 and the first ventilation pipe 21 can slide through the through holes 111.

[0033] Reference Figure 1 , Figure 2 and Figure 3 , a plurality of spare nets 3 are arranged outside the box 1, the number of spare nets 3 is equal to the number of filter nets 2, the top wall of the spare nets 3 is rotatably connected to a second ventilation pipe 31, each first ventilation pipe 21 is respectively fixedly connected to a second ventilation pipe 31 with a ventilation housing 4, the ventilation housing 4 is rotatably connected to the top wall of the replacement area 13, and the ventilation housing 4 can pass negative pressure airflow. A driving mechanism 5 is arranged in the replacement area 13, and the driving mechanism 5 is used to move the filter nets 2 and spare nets 3 to the replacement area 13 one by one, and to exchange the filter nets 2 and spare nets 3 in the replacement area 13.

[0034] The operator sprays powder particles into the spraying area 12 so that the powder particles adhere to the surface of the part. A negative pressure airflow is introduced into the ventilation housing 4, and the negative pressure airflow is transported to the filter screen 2 and the spraying area 12 in sequence through the first ventilation pipe 21. The powder particles that are not attached to the surface of the part in the spraying area 12 adhere to the surface of the filter screen 2 along with the negative pressure airflow. The driving mechanism 5 moves the filter screen 2 and the spare screen 3 upward to the replacement area 13 one by one, and the driving mechanism 5 exchanges the positions of the filter screen 2 and the spare screen 3 in the replacement area 13, and then moves the spare screen 3 downward to the spraying area 12, so that the spare screen 3 continues to filter the powder particles in the spraying area 12.

[0035] When one of the filters 2 is replaced, the remaining filters 2 in the spraying area 12 continue to filter dust, omitting the step of shaking the filter 2 to remove dust, achieving the function of replacing the filter 2 without stopping the machine, and improving the efficiency of separating powder particles from exhaust gas. In addition, omitting the step of shaking the filter 2 reduces the probability of dust deposited in the spraying area 12 being raised again, which is conducive to the recycling of dust deposited at the bottom of the spraying area 12.

[0036] Reference Figure 1 and Figure 3 The number of the driving mechanisms 5 is equal to the number of the filter screens 2. The driving mechanism 5 comprises a rotating source 51, which is fixedly mounted on the outer top wall of the ventilation housing 4. The driving shaft of the rotating source 51 is fixedly sleeved with a driving gear 52. The driving shaft of the rotating source 51 is fixedly connected with a transmission screw 53, which is threadedly connected with a transmission block 54. The two side walls facing the transmission block 54 are abutted with a limiting rod 55. The limiting rod 55 is fixedly connected with the partition 11, and a transmission spring 56 is fixedly connected with the top wall of the transmission block 54. The end of the transmission spring 56 away from the transmission block 54 is abutted with a conversion plate 57. The two ends of the conversion plate 57 are respectively fixedly connected with the first ventilation pipe 21 and the second ventilation pipe 31. The limiting rod 55 abuts with the two side walls facing the conversion plate 57. The top wall of the conversion plate 57 is fixedly connected with a conversion gear 58 that can mesh with the driving gear 52.

[0037] The forward rotation of the rotation source 51 drives the transmission screw 53 to rotate, and the limit rod 55 limits the rotation of the transmission block 54. The transmission screw 53 and the transmission block 54 form a screw slider structure. The forward rotation of the transmission screw 53 drives the transmission block 54 to move upward. The transmission block 54 drives the conversion plate 57 to move upward through the transmission spring 56, and the first ventilation pipe 21 and the second ventilation pipe 31 move synchronously with the conversion plate 57. The first ventilation pipe 21 drives the filter screen 2 to move to the replacement area 13, and the second ventilation pipe 31 drives the spare screen 3 to move to the replacement area 13. The conversion plate 57 drives the conversion gear 58 to move upward, so that the conversion plate 57 is separated from the limit rod 55. At the same time, the conversion gear 58 is meshed with the driving gear 52. The rotation source 51 drives the conversion gear 58 to rotate through the driving gear 52, and the conversion gear 58 drives the conversion plate 57 to rotate around the transmission screw 53, thereby exchanging the positions of the filter screen 2 and the spare screen 3. The rotation source 51 reverses and drives the filter screen 2 and the spare screen 3 to move downward, the spare screen 3 moves to the spraying area 12 to filter the dust, and the filter screen 2 moves outside the box body 1, and the operator removes the filter screen 2 for replacement.

[0038] The rotation of the transmission screw 53 not only drives the filter screen 2 and the spare screen 3 to move vertically, but also drives the filter screen 2 and the spare screen 3 to rotate, exchanging the positions of the filter screen 2 and the spare screen 3, thereby realizing the replacement of the filter screen 2 and the spare screen 3 in the replacement area 13.

[0039] Reference Figure 3The end of the transmission screw 53 away from the rotation source 51 is fixedly connected to the first connecting rod 6, and the first connecting rod 6 is fixedly sleeved with a first transmission gear 61, and the first transmission gear 61 is meshed with a connecting gear 62, and the connecting gear 62 is rotatably connected to the top wall of the partition 11. The connecting gear 62 is meshed with a first driven gear 22, and the first driven gear 22 is fixedly sleeved on the outer wall of the filter screen 2.

[0040] The rotation source 51 drives the first connecting rod 6 to rotate through the transmission screw 53. When the filter screen 2 is located in the spraying area 12 to filter dust, the first driven gear 22 is meshed with the connecting gear 62. The first connecting rod 6 drives the filter screen 2 to rotate through the first transmission gear 61, the connecting gear 62 and the first driven gear 22 in turn, so that the filter screen 2 can rotate when filtering dust, so that the outer wall of the filter screen 2 can evenly adsorb dust, thereby improving the dust adsorption effect of the filter screen 2.

[0041] Reference Figure 3 The outer wall of the spare net 3 is fixed with a second driven gear 32. After the filter net 2 is exchanged with the spare net 3, the second driven gear 32 can mesh with the connecting gear 62. When the spare net 3 is moved to the spraying area 12 to filter dust, the second driven gear 32 meshes with the connecting gear 62, and the connecting gear 62 drives the spare net 3 to rotate through the second driven gear 32.

[0042] Reference Figure 2 , Figure 4 and Figure 5 The bottom walls of the filter screen 2 and the backup screen 3 are both hinged with a transmission rod 23, and a return spring 24 is fixedly connected between the filter screen 2 and the transmission rod 23. The return spring 24 is also arranged between the backup screen 3 and the transmission rod 23.

[0043] Reference Figure 4 , Figure 5 and Figure 6 A resisting plate 7 is provided below the partition 11. The resisting plate 7 is in a quarter ring shape. The number of the resisting plates 7 is equal to the number of the through holes 111. The resisting plates 7 can cover the through holes 111 by rotation. A second connecting rod 71 is fixedly connected to the top wall of the resisting plate 7. The second connecting rod 71 passes through the partition 11. The second connecting rod 71 is rotationally connected to the partition 11, and the second connecting rod 71 is slidingly connected to the partition 11. A second transmission gear 72 is fixedly sleeved on one end of the second connecting rod 71 away from the resisting plate 7. The second transmission gear 72 can mesh with the connecting gear 62. A locking groove 112 is provided on the top wall of the partition 11. A locking block 73 that can mesh with the locking groove 112 is fixedly connected to the side wall of the second connecting rod 71.

[0044] When the filter screen 2 is located in the spraying area 12, the second transmission gear 72 does not mesh with the connecting gear 62, and the top wall of the material-repelling plate 7 does not contact the bottom wall of the partition 11. When the filter screen 2 moves upward to be replaced, the transmission rod 23 moves upward synchronously with the filter screen 2 to abut the bottom wall of the material-repelling plate 7, and the reset spring 24 pulls the transmission rod 23 upward, so that the transmission rod 23 squeezes the material-repelling plate 7 and moves upward, and the material-repelling plate 7 drives the second transmission gear 72 to move upward through the second connecting rod 71, so that the top wall of the material-repelling plate 7 abuts against the bottom wall of the partition 11, and the second transmission gear 72 meshes with the connecting gear 62, and the locking block 73 moves upward synchronously with the second connecting rod 71 to move out of the locking groove 112. The connecting gear 62 drives the second transmission gear 72 to rotate, and the second transmission gear 72 drives the locking block 73 and the material-repelling plate 7 to rotate through the second connecting rod 71, and the material-repelling plate 7 rotates to close the through hole 111. When the material-repelling plate 7 rotates, the quarter-ring-shaped material-repelling plate 7 can continuously close the through hole 111. The locking block 73 rotates to abut against the top wall of the partition 11, thereby limiting the downward movement of the second connecting rod 71 and the material-blocking plate 7, so that the material-blocking plate 7 can continue to close the through hole 111. The transmission rod 23 continues to move upward with the filter screen 2, and at the same time, the transmission rod 23 rotates to disengage from the material-blocking plate 7, and the transmission rod 23 and the filter screen 2 move upward to the replacement area 13.

[0045] When the spare net 3 moves downward into the spraying area 12, the connecting gear 62 reverses and drives the second transmission gear 72 to rotate, so that the second connecting rod 71 rotates and drives the locking block 73 to rotate. While the material resisting plate 7 rotates synchronously with the transmission rod 23, the material resisting plate 7 drives the locking block 73 and the second connecting rod 71 to move downward due to its own gravity. The locking block 73 moves downward into the locking groove 112, and the material resisting plate 7 rotates to disengage from the through hole 111. At the same time, the connecting gear 62 disengages from the second transmission gear 72, so that the spare net 3 can move downward to the spraying area 12 through the through hole 111.

[0046] When the filter 2 moves upward to be replaced, the material abutment plate 7 rotates to close the through hole 111, reducing the amount of dust entering the replacement area 13 and then spreading to the outside of the box 1 when the filter 2 is replaced, thereby reducing the negative impact of dust on the operation of parts in the replacement area 13.

[0047] Reference Figure 7 The top wall of the box body 1 is provided with an air inlet pipe 8 for introducing negative pressure airflow into the ventilation shell 4. A control shell 9 is rotatably provided inside the ventilation shell 4. The control shell 9 is fixedly connected with the air inlet pipe 8. An annular ventilation groove 91 is provided on the bottom wall of the control shell 9. A closing plate 92 is provided at the bottom wall of the control shell 9 where the ventilation groove 91 is not provided.

[0048] When the filter 2 and the spare filter 3 rotate in the replacement area 13, the first ventilation pipe 21 is connected with the annular ventilation groove 91, so that the filter 2 can still pass through the negative pressure airflow when rotating, so that the filter 2 can still absorb the dust on the surface when rotating, and reduce the amount of dust scattered to the replacement area 13 when the filter 2 is replaced. When the filter 2 rotates to the position of the spare filter 3, the first ventilation pipe 21 abuts against the closing plate 92, and the first ventilation pipe 21 and the filter 2 are stopped from passing through the negative pressure airflow, so that when the filter 2 is moved to the outside of the box 1 and removed, the closing plate 92 can prevent external impurities from being sucked into the control housing 9 and the air inlet pipe 8 through the first ventilation pipe 21, reducing the probability of external impurities blocking the air inlet pipe 8, and facilitating the replacement of the filter 2 moved to the outside of the box 1 by the operator.

[0049] The implementation principle of a gas spraying particle exhaust treatment device according to an embodiment of the present invention is as follows: an operator sprays powder particles into the spraying area 12 to make the powder particles adhere to the surface of the part. A negative pressure airflow is introduced into the ventilation housing 4, and the negative pressure airflow is sequentially transported to the filter screen 2 and the spraying area 12 through the first ventilation pipe 21. The powder particles in the spraying area 12 that are not attached to the surface of the part are attached to the surface of the filter screen 2 along with the negative pressure airflow.

[0050] When one of the filter screens 2 needs to be replaced after absorbing dust, the rotation source 51 rotates forward to drive the transmission screw 53 to rotate, and the limit rod 55 limits the rotation of the transmission block 54. The transmission screw 53 rotates forward to drive the transmission block 54 to move upward. The transmission block 54 drives the conversion plate 57 to move upward through the transmission spring 56, and the first ventilation pipe 21 and the second ventilation pipe 31 move synchronously with the conversion plate 57. The first ventilation pipe 21 drives the filter screen 2 to move to the replacement area 13, and the second ventilation pipe 31 drives the spare screen 3 to move to the replacement area 13. The conversion plate 57 drives the conversion gear 58 to move upward, so that the conversion plate 57 is disengaged from the limit rod 55, and the conversion gear 58 is meshed with the driving gear 52. The rotation source 51 drives the conversion gear 58 to rotate through the driving gear 52, and the conversion gear 58 drives the conversion plate 57 to rotate around the transmission screw 53, and the positions of the filter screen 2 and the spare screen 3 are exchanged. The rotation source 51 reverses and drives the filter screen 2 and the spare screen 3 to move downward, the spare screen 3 moves to the spraying area 12 to filter the dust, and the filter screen 2 moves outside the box body 1, and the operator removes the filter screen 2 for replacement.

[0051] In addition, it should be noted that in the description of the present invention, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0052] The above are preferred embodiments of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
