Description

Technical Field

[0001] This utility model relates to the field of triethyl phosphate production technology, specifically to an integrated green production device for triethyl phosphate. Background Technology

[0002] Triethyl phosphate is a colorless, easily flowing liquid with a slight fruity aroma. It is a high-boiling-point solvent, a plasticizer for rubber and plastics, a catalyst, and a raw material for the production of pesticides and insecticides. During the production of triethyl phosphate, a lot of exhaust gas is often generated. If these exhaust gases are not collected and recycled, they may cause serious air pollution and harm to human health. Therefore, green production equipment is needed to treat the exhaust gases.

[0003] In existing green production equipment for triethyl phosphate, a large number of impurity particles from the waste gas adhere to the equipment during use and are difficult to clean. The pores of the filter mechanism are gradually blocked by the impurity particles in the waste gas, resulting in a gradual decrease in waste gas treatment efficiency. The decrease in waste gas recovery speed will lead to blockage of pipelines and equipment, thereby affecting the normal operation of the production system and reducing the production efficiency of triethyl phosphate.

[0012] This utility model provides an integrated green production device for triethyl phosphate, which has the following beneficial effects:

[0013] (1) The present invention introduces the waste gas generated during the integrated triethyl phosphate production process into the installation box through the air inlet in the installation box. After the waste gas is filtered by the filter screen, the gas enters the upper part of the installation plate through the filter screen and exits through the air outlet pipe. After a period of use, the surface of the filter screen is covered with impurity particles, which affects the gas treatment efficiency of the production device. The first cam on the positioning frame, together with the spring, etc., realizes the intermittent and regular expansion and shaking of the elastic metal rod in the filter screen, which in turn drives the filter screen that is attached to it to expand and shake slightly, shaking off the impurities and dust attached to the surface of the filter screen. The shaken impurities will enter the dust collection box, reducing the blockage of the filter screen pores by impurities and affecting the green production efficiency of integrated triethyl phosphate.

[0014] (2) This utility model uses the mounting frame to drive the cleaning rollers in the mounting base to move on the surface of the filter screen, thereby cleaning the impurities that are difficult to shake off from the surface of the filter screen. The second toothed ring on the mounting ring in the mounting base and the gear on the adjusting frame work together to enable multiple sets of adjusting frames to drive multiple sets of cleaning rollers to rotate synchronously, so that multiple sets of cleaning rollers are only in contact with the surface of the filter screen. The drive wheel in the mounting frame works with the first toothed ring to enable the mounting base to drive the cleaning rollers to rotate on the surface of the filter screen. During the rotation, the cleaning rollers clean the impurities that are difficult to shake off from the filter screen. The auxiliary shaking rod achieves thorough cleaning of the filter screen, avoiding the gradual blockage of the filter screen pores by impurity particles in the exhaust gas, which would lead to a gradual decrease in exhaust gas treatment efficiency, thereby affecting the normal operation of the production system and reducing the production efficiency of triethyl phosphate.

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3As shown in this embodiment, an integrated green production device for triethyl phosphate includes a mounting box 1. A mounting plate 6 is fixedly installed inside the mounting box 1. A positioning frame 7 and a fixing frame 8 are also fixedly installed inside the mounting box 1. The positioning frame 7 and the fixing frame 8 are located on opposite sides of the mounting plate 6. Three sets of filter screens 9 are installed between the mounting plate 6 and the fixing frame 8. Three sets of symmetrically distributed shaking rods 11 are provided on the positioning frame 7. The upper ends of the three sets of shaking rods 11 are slidably connected to the positioning frame 7. The three sets of shaking rods 11 are located on three... The filter screen 9 is fitted inside and against the inner wall of the filter screen 9. The lower ends of the three sets of shaking rods 11 are fixedly installed with the filter screen 9 and the fixing frame 8. A first spring 12 is sleeved on the positioning frame 7. The two ends of the first spring 12 are fixedly connected to the shaking rods 11 and the positioning frame 7 respectively. A first cam 13 is rotatably installed on the positioning frame 7. The first cam 13 is fitted against the upper end of the shaking frame. A dust collection box 2 is fixedly installed below the installation box 1. A cover plate 3 is rotatably installed on the dust collection box 2. An air inlet 4 is opened on the installation box 1. An air outlet 5 is provided at the top of the installation box 1. A baffle 10 corresponding to the air inlet 4 is fixedly installed inside the installation box 1. Waste gas generated during the integrated triethyl phosphate production process is introduced into the installation box 1 through the air inlet 4. After the waste gas is filtered and impurities are separated from it by the filter screen 9, the gas enters the area above the installation plate 6 through the filter screen 9 and exits through the air outlet pipe. After a period of use, impurity particles adhere to the surface of the filter screen 9, affecting the gas treatment efficiency of the production device. The motor on the positioning frame 7 drives the first cam 13 to rotate. The first cam 13 is in contact with the upper end of the shaking rod 11. Therefore, during the rotation of the first cam 13, the shaking rod 11 is pushed down intermittently, causing the elastic metal material shaking rod 11 to deform, bend and expand outward, thereby pushing the filter screen 9 that is in contact with it outward. With the help of the first spring 12, the shaking rod 11 expands and contracts back and forth on the positioning frame 7, thereby causing the filter screen 9 to expand, contract and shake intermittently, shaking off the impurity particles attached to the surface of the filter screen 9, thus completing a certain degree of cleaning of the filter screen 9.

[0023] like Figure 4 and Figure 5As shown, the mounting plate 6 has three sets of symmetrically distributed mounting rods 14. A first push rod 15 is slidably installed within each of the three sets of mounting rods 14. A second push rod 16 is slidably installed within each of the three sets of first push rods 15. A mounting frame 17 is fixedly installed at the lower end of each second push rod 16. A mounting seat 18 is rotatably installed within the mounting frame 17. The three sets of mounting seats 18 and mounting frames 17 are slidably sleeved with their corresponding filter screen covers 9. A first toothed ring 19 is sleeved on the mounting seat 18. A drive wheel 20 is rotatably installed within the mounting frame 17, meshing with the first toothed ring 19. A mounting ring 21 is rotatably installed within the mounting seat 18. A second toothed ring 22 is sleeved on the mounting ring 21. Multiple sets of annularly distributed adjusting frames 23 are rotatably installed within the mounting seat 18.

Cleaning rollers 25 are rotatably mounted on each set of adjusting brackets 23, and the cleaning rollers 25 are in contact with the surface of the filter screen 9. A motor inside the mounting base 18 drives the adjusting brackets 23 and the gears 24 on them to rotate. This, in conjunction with the gears 24 and the second gear rings 22 on the mounting ring 21, achieves synchronous rotation adjustment of the multiple adjusting brackets 23. The cleaning rollers 25 on the multiple adjusting brackets 23 rotate inward synchronously and tightly contact the surface of the filter screen 9. A motor inside the mounting bracket 17 drives the drive wheel 20 to rotate, which, in conjunction with the first gear ring 19, causes the mounting base 18 to drive the cleaning rollers 25 to rotate on the surface of the filter screen 9, completing the adjustment of the filter screen. 9. Cleaning of surface impurities not shaken off: A brush 30 is slidably mounted on the mounting frame 17, corresponding to the cleaning roller 25. A slide rod 31 is fixedly mounted inside the mounting frame 17, and two sets of symmetrically distributed second springs 32 are sleeved on the slide rod 31. The brush 30 is slidably sleeved with the slide rod 31. The two ends of the second springs 32 are fixedly connected to the brush 30 and the slide rod 31, respectively. A second cam 33 is rotatably mounted on the mounting frame 17, and the second cam 33 is fitted with the brush 30. After the cleaning roller 25 is used, the multiple sets of cleaning rollers 25 are adjusted to fit with the brush 30 through the action of the mounting ring 21, the second gear ring 22, and the gear 24. During the rotation of the second cam 33 driven by the motor on the mounting frame 17, the second cam 33 is coordinated with the second cam 30. Spring 32 and slide bar 31 enable the brush 30 to reciprocate on the mounting bracket 17. During the rotation of the cleaning roller 25 driven by the mounting base 18, the brush 30, which is in contact with and reciprocates with it, can clean the impurities on the surface of the cleaning roller 25. A screw 26 is rotatably installed inside the mounting rod 14, and a screw tube 28 is rotatably installed inside the first push rod 15. The screw 26 passes through the first push rod 15 and is threadedly connected to the first push rod 15. The screw tube 28 passes through the second push rod 16 and is threadedly connected to the second push rod 16. Two sets of symmetrically distributed slots 27 are provided on the screw 26, and two sets of symmetrically distributed blocks 29 are provided inside the screw tube 28. The blocks 29 are correspondingly set with the slots 27, and the screw tube 28 is slidably sleeved with the screw 26 through the blocks 29.

[0024] This utility model provides an integrated triethyl phosphate green production device. The specific working principle is as follows: Waste gas generated during the integrated triethyl phosphate production process is introduced into the installation box 1 through the air inlet 4. After impurities are filtered out by the filter screen 9, the gas passes through the filter screen 9 and enters above the mounting plate 6, exiting through the outlet pipe. After a period of use, impurity particles adhere to the surface of the filter screen 9, affecting the gas treatment efficiency of the production device. The motor on the positioning frame 7 drives the first cam 13 to rotate. The first cam 13 is in contact with the upper end of the shaking rod 11. Therefore, during the rotation of the first cam 13, the shaking rod 11 is intermittently pushed downwards, causing the elastic metal material shaking rod 11 to deform, bend, and expand outwards, thereby pushing the filter screen 9 that is in contact with it. In conjunction with the first spring 12, the shaking rod 11 reciprocates on the positioning frame 7, causing the filter screen 9 to intermittently expand, contract, and shake, shaking off the impurity particles adhering to the surface of the filter screen 9, thus completing a certain degree of cleaning of the filter screen 9. The installation base 18 contains… The motor drives the adjustment frame 23 and the gear 24 on the adjustment frame 23 to rotate. In conjunction with multiple sets of gears 24 and the second toothed ring 22 on the mounting ring 21, the synchronous rotation adjustment of multiple sets of adjustment frames 23 is achieved. The cleaning rollers 25 on the multiple sets of adjustment frames 23 rotate inward synchronously and fit tightly against the surface of the filter screen 9. The motor in the mounting frame 17 drives the drive wheel 20 to rotate. In conjunction with the first toothed ring 19, the mounting seat 18 drives the cleaning rollers 25 to rotate on the surface of the filter screen 9 to clean the impurities that have not been shaken off from the surface of the filter screen 9. After the cleaning rollers 25 are used, the mounting ring 21, the second toothed ring 22 and the gears 24 adjust the multiple sets of cleaning rollers 25 to fit against the brush 30. During the rotation of the second cam 33 driven by the motor on the mounting frame 17, the second spring 32 and the slide rod 31 can realize the reciprocating movement of the brush 30 on the mounting frame 17. During the rotation of the cleaning rollers 25 driven by the mounting seat 18, the brush 30, which fits against and reciprocates with them, can clean the impurities on the surface of the cleaning rollers 25.
