The extracted coating will be evenly coated on the inner wall of the through hole, and a coating film will also be formed on the upper end of the ceramic material. The position of the ceramic material is then changed again so that its lower end is facing upward, and the coating is poured on the ceramic material again, and a vacuum machine is used for suction, and then the coating is adsorbed on the carrier to form a coating layer, thereby completing the coating preparation of the VOC catalyst.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods. Embodiment 1

[0022] like Figures 1 to 8 As shown, a VOC industrial catalyst quantitative coating device according to an embodiment of the present invention comprises a base 1, a support frame 2 is installed on the upper end surface of the base 1, a U-shaped protective cover 3 is fixedly connected to the upper end of the support frame 2, and an inlet and outlet are opened at one end of the U-shaped protective cover 3 for placing ceramic materials, a fixed block 7 is fixedly connected to the upper end of the U-shaped protective cover 3, a support slide 8 is slidably connected inside the fixed block 7, a support plate 10 is fixedly connected to the upper end of the support slide 8, and a quantitative material discharging coating component 9 is installed on the upper end of the support plate 10; The quantitative feeding and coating assembly 9 includes a three-way pipe 91 fixedly connected to the upper end surface of the support plate 10, two annular rubber blocks 92 are fixedly connected to the inner cavity of the three-way pipe 91, and a conical sealing plug 94 is slidably connected to the lower end of each annular rubber block 92, a piston 97 is slidably connected to the inner cavity of one side of the three-way pipe 91, and a push rod 98 is fixedly connected to one end of the piston 97; The inner cavity of the U-shaped protective cover 3 is rotatably connected to a rotating disk 4, a coating port 34 is provided on the lower end surface of the support plate 10, and the lower end of the three-way pipe 91 is fixedly connected to the coating port 34 for discharging paint.

[0023] Specifically, in the prior art, a cylindrical ceramic material is usually used as a base, and then the ceramic material is mounted on a coating device, and the coating is poured on the ceramic material, and at the same time, a vacuum machine is used to pump from the lower end of the ceramic material, so that the coating is extracted from the honeycomb through-holes in the ceramic material, and the coating is adsorbed on the carrier to form a coating, thereby completing the production and preparation of the VOC catalyst. However, this operation method is not only cumbersome, but also unable to control the emission of the coating, and too much coating is likely to cause the honeycomb through-holes of the ceramic material to be blocked, thereby affecting the quality of the VOC industrial catalyst; The present invention conveys the honeycomb ceramic material into the U-shaped protective cover 3 through an external conveyor belt, and drives the rotating disk 4 to drive the ceramic material to be transferred, and then transfers the ceramic material to the bottom of the coating port 34, and then drives the support plate 10 to move downward, and makes the support plate 10 drive the support slide column 8 to slide inside the fixed block 7, and at the same time, the support plate 10 covers the ceramic material with the coating port 34, and then drives the piston 97 to slide in the inner cavity of the three-way pipe 91, and makes the piston 97 pump the inner cavity of the three-way pipe 91 to form a negative pressure, and then pumps the conical sealing plug 94 on the upper part of the three-way pipe 91 to open, and at the same time extracts a certain amount of coating into the three-way pipe 91, and as the piston 97 squeezes the coating in the inner cavity of the three-way pipe 91, the coating opens the three-way pipe 91. The conical sealing plug 94 at the lower part of the inner cavity of the through tube 91 is discharged into the coating port 34, and the coating is poured into the ceramic material. At the same time, the coating is pushed into the honeycomb mesh of the ceramic material by the piston 97 under the slight pressure exerted by the coating and flows into the bottom of the ceramic material. Moreover, this slight pressure is applied in the process of slowly discharging the coating, thereby avoiding excessive pressure causing cracks and damage to the inner wall of the pores of the ceramic material. In the process of coating flow, the surface of the ceramic material is adhered and coated, thereby avoiding excessive coating discharge, which causes the coating to block the honeycomb pores of the ceramic material, affecting the production coating efficiency and quality of the VOC industrial catalyst, thereby solving the above-mentioned problems.

[0024] like Figure 1 , Figure 4 and Figure 6As shown, a servo push rod 12 is installed on the upper end surface of the support plate 10, and a push block 11 is slidably connected to the outside of the push rod 98. A fastening bolt 13 is threadedly connected to the upper end of the push block 11, and the fastening bolt 13 is used to fix the limit push rod 98. One end of the push block 11 is fixedly connected to the piston rod end of the servo push rod 12.

[0025] like Figure 4 and Figure 6 As shown, two fixing frames 93 are fixedly connected to the inner cavity of the three-way pipe 91, and sliding rods 96 are slidably connected inside the two fixing frames 93. The upper end of the sliding rod 96 is fixedly connected to the conical sealing plug 94. The lower end of the conical sealing plug 94 is fixedly connected to the second spring 95, and the second spring 95 is fixedly connected to the fixing frame 93.

[0026] Specifically, the servo push rod 12 is started to drive the push block 11, and the push block 11 drives the push rod 98 by the fastening bolt 13, and at the same time, the push rod 98 pulls the piston 97 to slide in the inner cavity of the three-way tube 91, thereby forming a negative pressure in the inner cavity of the three-way tube 91, thereby opening the conical sealing plug 94 at the upper part of the inner cavity of the three-way tube 91, and drawing a certain amount of paint into the inner cavity of the three-way tube 91, and then the piston 97 is pushed by the driving push rod 98 to slide in the inner cavity of the three-way tube 91, thereby squeezing the paint in the inner cavity of the three-way tube 91, and squeezing the conical sealing plug 94 at the lower part of the inner cavity of the three-way tube 91, and passing through the coating port 34. The discharged coating will be discharged onto the ceramic material under pressure, and flow into the inlet port 6 through the honeycomb through holes in the ceramic material. When the coating flows through the honeycomb through holes in the ceramic material, the ceramic material will be coated. At the same time, the coating flowing into the inlet port 6 just fills the entire port 6 and coats the lower end of the ceramic material, thereby solving the problem of the existing VOC industrial catalyst quantitative coating equipment that after coating the upper end of the ceramic material, the ceramic material needs to be rotated and replaced to coat the other end of the ceramic material, which is not only cumbersome to operate, but also affects the processing and production efficiency of the VOC industrial catalyst.

[0027] like Figure 4 and Figure 6 As shown, a plurality of slots 99 are provided on the outside of the push rod 98, and the plurality of slots 99 are plugged into the fastening bolts 13 for adjusting the progress of the push rod 98 in the inner cavity of the three-way pipe 91, so as to adjust the amount of paint to be extracted and discharged.

[0028] Specifically, when it is necessary to adjust the discharge amount of the paint, the fastening bolt 13 is removed from the inside of the pushing block 11, and then the discharge amount of the paint is adjusted as needed by pulling the pushing rod 98 to drive the piston 97 to slide in the inner cavity of the tee pipe 91, and then the position of the piston 97 in the inner cavity of the tee pipe 91 is adjusted, and then the fastening bolt 13 is installed inside the pushing block 11 again, and the pushing rod 98 is fixed by inserting it into the inner cavity of the slot 99, thereby realizing the adjustment of the extraction and discharge amount of the paint, so as to adjust the paint demand according to the coating of different materials.

[0029] like Figure 2 and Figure 7 As shown, the outside of the three-way pipe 91 is slidably connected to a sliding frame 18, and the sliding frame 18 is slidably connected to the support plate 10, a sealing cover 28 is fixedly connected to the lower end of the sliding frame 18, a plurality of tension springs 27 are fixedly connected to the upper wall of the inner cavity of the sliding frame 18, and the tension spring 27 is fixedly connected to the support plate 10, a hydraulic push rod 17 is arranged inside the U-shaped protective cover 3, and the piston rod end of the hydraulic push rod 17 is fixedly connected to the support plate 10.

[0030] like Figure 1 , Figure 2 and Figure 4 As shown, a bracket 14 is fixedly connected to the upper end surface of the support plate 10, a storage barrel 15 is installed in the inner cavity of the bracket 14, a feeding port 16 is opened outside the storage barrel 15, and the storage barrel 15 is used to store paint.

[0031] Specifically, when coating the ceramic material, the support plate 10 is driven to move downward, and then the support plate 10 drives the sliding frame 18 to move downward, and the sliding frame 18 drives the sealing cover 28 to move synchronously, and the sealing cover 28 is used to cover the ceramic material below, and then as the support plate 10 continues to move downward, the sealing cover 28 will move upward and push the sliding frame 18, so that the sliding frame 18 stretches the tension spring 27 to expand, and at the same time, the support plate 10 uses the coating port 34 to dock with the ceramic material, and then the quantitative feeding and coating component 9 is used to discharge the coating to coat the ceramic material, and at the same time, the pressure of the coating discharged by the quantitative feeding and coating component 9 is used to slowly apply pressure to the coating, and the coating flows through the through hole of the ceramic material to the inner cavity of the through port 6 for storage, thereby realizing the processing of VOC industrial catalysts. Embodiment 2

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, a plurality of placement grooves 5 are provided on the outside of the rotating disk 4, and a through opening 6 is provided at the bottom of the inner cavity of each placement groove 5 for discharging the recovered paint. A servo motor 23 is installed on the upper end surface of the base 1, and the output shaft of the servo motor 23 passes through the U-shaped protective cover 3 and is fixedly connected to the rotating disk 4.

[0033] like Figure 1and Figure 3 As shown, a plurality of receiving grooves 19 are provided on the lower end surface of the rotating disk 4, and a first spring 21 is fixedly connected to the bottom of the inner cavity of the plurality of receiving grooves 19, a sealing block 20 is fixedly connected to one end of the first spring 21, and the sealing block 20 is used to seal the through opening 6, a groove 29 is provided on one side of the lower end surface of the sealing block 20, a micro spring 30 is arranged at the bottom of the inner cavity of the groove 29, and a stop block 22 is fixedly connected to one end of the micro spring 30.

[0034] Specifically, when processing VOC industrial catalysts, the ceramic material is transported into the U-shaped protective cover 3 through the external conveyor belt, and is pushed into the placement groove 5 in the rotating disk 4, and then the rotating disk 4 is driven to rotate, and then the rotating disk 4 drives the ceramic material to be transported and moved. When the rotating disk 4 drives the ceramic material to be transported and moved, the ceramic material will contact the inner wall of the U-shaped protective cover 3, and then the U-shaped protective cover 3 is used to abut the ceramic material to make it completely slide into the placement groove 5. At the same time, the rotating disk 4 transports the ceramic material to the bottom of the coating port 34 to wait for coating work. After the ceramic material is poured with paint, the rotating disk 4 is driven to rotate again, and the rotating disk 4 drives the ceramic material to be transported and moved. When the rotating disk 4 drives the ceramic material to the recovery port 25, the abutment block 22 will abut against the recovery port 25, and then the rotating disk 4 is continuously driven, and the abutment block 22 will drive the sealing block 20 to slide into the receiving groove 1 9 Then, the port 6 is opened in the inner cavity, and the port 6 is connected to the recovery port 25, and then the vacuum machine is started to cooperate with the funnel 24 to extract the excess paint in the ceramic material, and the through holes of the ceramic material are also pumped to prevent the problem of paint residue. At the same time, the excess paint is discharged into the feeding port 16 and enters the storage barrel 15 for recovery in cooperation with the conduit, thereby completing the coating of the ceramic material, thereby solving the problem that the existing VOC industrial catalyst quantitative coating equipment usually uses a fence to install the upper end of the ceramic material, and then pours the paint into the cavity formed by the fence, and uses a vacuum machine to pump from the lower end of the ceramic material, so that the paint is extracted from the honeycomb through holes in the ceramic material, and then the paint is adsorbed on the carrier to form a coating. However, this operation method is not only cumbersome, but also unable to cyclically and quickly discharge the paint from the ceramic material for coating, affecting the processing and production efficiency of the VOC industrial catalyst.

[0035] like Figure 5 and Figure 8 As shown, a recovery port 25 is provided at the bottom of the inner cavity of the U-shaped protective cover 3, and the inner cavity of the recovery port 25 is connected to the through port 6. The lower end surface of the U-shaped protective cover 3 is located outside the recovery port 25 and is fixedly connected to a funnel 24, and a recovery interface 26 is provided at the lower end of the funnel 24. A vacuum pump is installed at the recovery interface 26, and the discharge port of the vacuum pump is connected to the feeding port 16 through a conduit.

[0036] like Figure 5 and Figure 8As shown, a plurality of slide grooves 31 are evenly formed on the inner wall of the U-shaped protective cover 3, and elastic members 32 are fixedly connected to the inner cavities of the plurality of slide grooves 31, and a pressing block 33 is fixedly connected to one end of the elastic member 32 for pressing against materials to prevent movement.

[0037] Specifically, when the rotating disk 4 drives the ceramic material to be transported and moved below the coating port 34, the elastic member 32 in the inner cavity of the slide groove 31 pops up the pressure block 33, and makes the pressure block 33 abut against the ceramic material in the inner cavity of the placement groove 5, thereby ensuring the position of the ceramic material in the inner cavity of the placement groove 5, so as to facilitate the docking of the lower end of the placement groove 5 with the through port 6, thereby preventing the ceramic material from deviating from the central position of the inner cavity of the placement groove 5, affecting the adsorption and recovery of the coating, and resulting in the inability to evenly coat the coating in each honeycomb through-hole of the ceramic material.

[0038] Working principle: when processing VOC industrial catalyst, the ceramic material is conveyed into the U-shaped protective cover 3 through the external conveyor belt, and pushed into the placement groove 5 in the rotating disk 4, and then the rotating disk 4 is driven to rotate, and then the rotating disk 4 drives the ceramic material to be conveyed and moved. When the rotating disk 4 drives the ceramic material to be conveyed and moved, the ceramic material will contact the inner wall of the U-shaped protective cover 3, and then the U-shaped protective cover 3 is used to abut the ceramic material to make it completely slide into the placement groove 5. At the same time, the rotating disk 4 conveys the ceramic material to the bottom of the coating port 34 to wait for coating work. After the ceramic material is poured with paint, it is again The rotating disk 4 is driven to rotate, and the rotating disk 4 drives the ceramic material to be transported and moved. When the rotating disk 4 drives the ceramic material to be transported to the recovery port 25, the abutment block 22 will abut against the recovery port 25, and then the rotating disk 4 is continuously driven, and the abutment block 22 will drive the sealing block 20 to slide into the inner cavity of the receiving groove 19 and then open the through port 6, and make the through port 6 communicate with the recovery port 25, and then start the vacuum pump to cooperate with the funnel 24 to extract the excess paint in the ceramic material, and at the same time cooperate with the conduit to discharge the excess paint into the feeding port 16 and enter the storage barrel 15 for recovery, thereby completing the coating work of the ceramic material; In the process of the rotating disk 4 driving the ceramic material to be transported to the lower part of the coating port 34, the elastic member 32 in the inner cavity of the slide groove 31 bounces up the pressing block 33, and the pressing block 33 abuts against the ceramic material in the inner cavity of the placement groove 5, thereby ensuring the position of the ceramic material in the inner cavity of the placement groove 5, so that the lower end of the placement groove 5 is connected with the through port 6, and the ceramic material is prevented from deviating from the middle position of the inner cavity of the placement groove 5, which affects the adsorption and recovery of the coating; The servo push rod 12 is started to drive the push block 11, and the push block 11 drives the push rod 98 by the fastening bolt 13. At the same time, the push rod 98 pulls the piston 97 to slide in the inner cavity of the three-way tube 91, thereby forming a negative pressure in the inner cavity of the three-way tube 91, thereby opening the conical sealing plug 94 at the upper part of the inner cavity of the three-way tube 91, and drawing a certain amount of paint into the inner cavity of the three-way tube 91. Then, the piston 97 is pushed to slide in the inner cavity of the three-way tube 91 by driving the push rod 98, thereby squeezing the three-way tube 91. 1, and the coating material is squeezed out of the conical sealing plug 94 at the lower part of the inner cavity of the three-way pipe 91, and discharged through the coating port 34. The discharged coating material is discharged onto the ceramic material under pressure, and flows into the inlet port 6 through the honeycomb through-holes in the ceramic material. When the coating material flows through the honeycomb through-holes in the ceramic material, the ceramic material is coated. At the same time, the coating material flowing into the inlet port 6 just fills the entire through-hole 6 and coats the lower end of the ceramic material, thereby processing the VOC industrial catalyst.
