Description

Technical Field

[0001] This utility model relates to the field of chemical raw material production technology, and in particular to a pressure compensation device for chemical raw material production. Background Technology

[0002] In the chemical raw material production process, pressure compensation devices are crucial equipment. Their main function is to adjust the pressure within the reactor or container in real time according to pressure changes caused by chemical reactions or material variations. In chemical raw material production, the application of pressure compensation devices effectively controls internal pressure fluctuations, preventing excessively high or low pressures from adversely affecting the production process. Simultaneously, pressure compensation devices can improve the stability and controllability of the production process, reducing the risk of production accidents.

[0003] For example, Chinese utility model patent CN218680774U includes a pressure tank with a compensator installed on its top. The compensator includes a connecting shell with a cylindrical body penetrating its center. The side wall of the connecting shell has air holes, and both ends of the connecting shell have internal threads, one of which connects to the pressure tank. A cover is installed on the connecting shell at the end away from the pressure tank. The cover is hollow and has an opening at one end with an external thread that matches the internal thread. This addresses the problem of cumbersome internal parts replacement in traditional pressure compensation devices. Although this patent can ensure automatic pressure relief while making internal parts replacement convenient, its fixed pressure triggering conditions prevent adjustment of the triggering pressure according to the requirements of the processed raw materials, thus limiting its applicability. Therefore, we propose a pressure compensation device for chemical raw material production. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the technical problems existing in the prior art, and to provide a pressure compensation device for chemical raw material production that can solve the problem of not being able to adjust the trigger pressure according to the situation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a pressure compensation device for chemical raw material production, comprising a pressure tank, a threaded connecting sleeve fixedly connected to the upper surface of the pressure tank, a first mounting sleeve threadedly fitted onto the inner wall of the threaded connecting sleeve, a baffle fixedly connected to the inner wall of the first mounting sleeve, a through groove extending from the lower surface of the baffle on its upper surface, a threaded groove on the upper surface of the first mounting sleeve, a second mounting sleeve threadedly connected to the inside of the threaded groove, a mounting disc threadedly connected to the inner wall of the second mounting sleeve, a threaded rod rotatably connected to the lower surface of the mounting disc, an adjusting ring threadedly connected to the outer surface of the threaded rod, a spring fixedly connected to the lower surface of the adjusting ring, a sealing disc fixedly connected to the lower end of the spring, the sealing disc slidably fitted onto the outer surface of the threaded rod, and a limit component provided on the adjusting ring.

[0006] Preferably, the limiting component includes two sliding plates, both of which are fixedly connected to the outer surface of the adjusting ring. Two limiting rods are fixedly connected to the lower surface of the mounting plate. The two sliding plates are slidably sleeved on the outer surfaces of the two limiting rods respectively. A slot is provided at the lower end of the threaded rod, and a second through groove extending from the lower surface of the mounting plate is provided on the upper surface of the mounting plate.

[0007] Preferably, the outer surface of the second mounting sleeve has an air outlet extending into its interior, the upper surface of the second mounting sleeve has a second threaded groove, and a top cover is threaded into the inner part of the second threaded groove.

[0008] Preferably, a filter cylinder is fixedly connected to the inner wall of the second mounting sleeve, a second limiting rod is fixedly connected to the bottom wall of the filter cylinder, and a through hole extending from the upper surface of the filter cylinder is opened on the lower surface of the filter cylinder.

[0009] Preferably, the upper surface of the filter cylinder is provided with a third threaded groove, and the filter top cover is fitted inside the third threaded groove.

[0010] Preferably, the upper surface of the filter top cover is also provided with a through hole extending to its lower surface, and the filter plate is slidably sleeved on the outer surface of the second limiting rod.

[0011] Preferably, a support ring is fixedly connected to the upper surface of the filter plate, a connecting sleeve is slidably sleeved on the outer surface of the second limiting rod, and a displacement rod is slidably sleeved inside the filter plate.

[0012] Preferably, the outer surface of the displacement rod is also fitted with a connecting sleeve, the two connecting sleeves are fixedly connected, and the upper end of the displacement rod slides through the upper surface of the filter top cover.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the pressure compensation device for chemical raw material production needs to adjust the pressure required to lift the sealing disc, the adjusting ring moves vertically when the threaded rod is rotated because the movement trajectory of the adjusting ring is restricted by the limiting component. When the adjusting ring moves downward, the sealing disc cannot move because it is blocked by the baffle. Therefore, the adjusting ring will compress the spring when it moves, thereby increasing the air pressure required to lift the sealing disc again. Through the above structure, the pressure release trigger pressure can be adjusted by the movement of the adjusting ring when processing different chemical raw materials, thereby adapting to different raw materials and processing methods and improving the applicability of the overall device.

[0015] (2) In this pressure compensation device for chemical raw material production, after the gas enters the interior of the second mounting sleeve, it will enter the interior of the filter cylinder through the through hole. After being filtered by the triple filter plate, it will be discharged through the through hole on the filter top cover. When replacing and cleaning the filter plate, the top cover and the filter top cover are removed in sequence. Then, by lifting the displacement rod, the displacement rod drives the connecting sleeve to move. After the connecting sleeve moves, it drives the filter plate to move up, thereby disassembling the filter plate. Through the above structure, the gas discharged during the processing of chemical raw materials can be filtered by the filter plate before being discharged, avoiding the overflow of harmful gases and reducing the air quality of the surrounding air, and also avoiding harm to the workers.

[0023] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Please see Figure 1-5 This utility model provides a technical solution: a pressure compensation device for chemical raw material production, including a pressure tank 1. A threaded connecting sleeve 2 is fixedly connected to the upper surface of the pressure tank 1. A first mounting sleeve 3 is threadedly fitted onto the inner wall of the threaded connecting sleeve 2. A baffle 4 is fixedly connected to the inner wall of the first mounting sleeve 3. A through groove extending from the lower surface of the baffle 4 is formed on the upper surface of the baffle 4. A threaded groove is formed on the upper surface of the first mounting sleeve 3. A second mounting sleeve 5 is threadedly connected to the inside of the threaded groove. A mounting disc 6 is threadedly connected to the inner wall of the second mounting sleeve 5. A threaded rod 7 is rotatably connected to the lower surface of the mounting disc 6. An adjusting ring 8 is threadedly connected to the outer surface of the threaded rod 7. A spring 9 is fixedly connected to the lower surface of the adjusting ring 8. A sealing disc 10 is fixedly connected to the lower end of the spring 9. The sealing disc 10 is slidably fitted onto the outer surface of the threaded rod 7. The adjusting ring 8 is provided with a limit component. During normal use... When the internal pressure of the pressure tank 1 is too high, the air pressure will lift the sealing disc 10. When the sealing disc 10 is lifted, the spring 9 is compressed. After the sealing disc 10 is lifted, the gas enters the interior of the second mounting sleeve 5 through the through groove. When it is necessary to adjust the pressure required to lift the sealing disc 10, the threaded rod 7 is rotated. Since the movement trajectory of the adjusting ring 8 is restricted by the limiting component, the adjusting ring 8 will move vertically in sync when the threaded rod 7 rotates. When the adjusting ring 8 moves downward, the sealing disc 10 cannot move because it is blocked by the baffle 4. Therefore, the spring 9 will be compressed when the adjusting ring 8 moves, thereby increasing the pressure required to lift the sealing disc 10 again. Through the above structure, the pressure release trigger pressure can be adjusted by the movement of the adjusting ring 8 when processing different chemical raw materials, thereby adapting to different raw materials and processing methods and improving the applicability of the overall device.

[0025] Furthermore, the limiting assembly includes two sliding plates 11, both of which are fixedly connected to the outer surface of the adjusting ring 8. Two limiting rods 12 are fixedly connected to the lower surface of the mounting plate 6. The two sliding plates 11 are slidably sleeved on the outer surfaces of the two limiting rods 12. A slot 13 is provided at the lower end of the threaded rod 7. A second through groove 14 extending from the lower surface of the upper surface of the mounting plate 6 is provided. An air outlet 15 extending into the interior is provided on the outer surface of the second mounting sleeve 5. A second threaded groove is provided on the upper surface of the second mounting sleeve 5, and a top thread is threadedly sleeved inside the second threaded groove. The filter cylinder 17 is fixedly connected to the inner wall of the cover 16 and the second mounting sleeve 5. A second limiting rod 18 is fixedly connected to the bottom wall of the filter cylinder 17. A through hole 19 extending from the upper surface of the filter cylinder 17 is formed on its lower surface. A third threaded groove 20 is formed on the upper surface of the filter cylinder 17. A filter top cover 21 is threaded inside the third threaded groove 20. A through hole 19 extending from the lower surface of the filter top cover 21 is also formed on its upper surface. A filter plate 22 is slidably fitted onto the outer surface of the second limiting rod 18. A support ring 23 is fixedly connected to the upper surface of the filter plate 22. The second limiting rod...

[0026] A connecting sleeve 24 is slidably fitted onto the outer surface of rod 18, and a displacement rod 25 is slidably fitted onto the inside of filter plate 22. A connecting sleeve 24 is also fitted onto the outer surface of displacement rod 25. The two connecting sleeves 24 are fixedly connected. The upper end of displacement rod 25 slides through the upper surface of filter top cover 21 and is inserted into slot 13 using a tool. Then, the threaded rod 7 can be rotated. At this time, it is necessary to ensure that the mounting plate 6 does not rotate. When the threaded rod 7 rotates, the movement trajectory of adjusting ring 8 is limited by sliding plate 11 and limiting rod 12. Simultaneously, after the gas enters the interior of the second mounting sleeve 5, it enters the interior of filter cylinder 17 through through hole 19. After being filtered by the triple filter plate 22, the gas is discharged through the through hole 19 on the filter top cover 21. When replacing or cleaning the filter plate 22, first remove the top cover 16 and the filter top cover 21 in sequence. Then, by lifting the displacement rod 25, the connecting sleeve 24 is moved. After the connecting sleeve 24 moves, the filter plate 22 is moved upward, thereby disassembling the filter plate 22. Through the above structure, the gas discharged during the processing of chemical raw materials can be filtered by the filter plate 22 before being discharged, avoiding the overflow of harmful gases and reducing the air quality of the surrounding air, and also avoiding harm to the workers.

[0027] Working principle: During normal use, when the internal pressure of the pressure tank 1 is too high, the air pressure will lift the sealing disc 10. When the sealing disc 10 is lifted, the spring 9 is compressed. After the sealing disc 10 is lifted, the gas enters the interior of the second mounting sleeve 5 through the through groove. When it is necessary to adjust the pressure required to lift the sealing disc 10, the threaded rod 7 is rotated. Since the movement trajectory of the adjusting ring 8 is restricted by the limiting component, the rotation of the threaded rod 7 will synchronously drive the adjusting ring 8 to move vertically. When the adjusting ring 8 moves downward, the sealing disc 10 cannot move because it is blocked by the baffle 4. Therefore, the movement of the adjusting ring 8 will compress the spring 9, thereby increasing the air pressure required to lift the sealing disc 10 again. A tool is used to engage the locking mechanism. Inside the groove 13, the threaded rod 7 can then be rotated. At this time, it is necessary to ensure that the mounting plate 6 does not rotate. When the threaded rod 7 rotates, the sliding plate 11 and the limiting rod 12 are used to limit the movement trajectory of the adjusting ring 8. At the same time, after the gas enters the interior of the second mounting sleeve 5, it will enter the interior of the filter cylinder 17 through the through hole 19. After being filtered by the triple filter plate 22, it will be discharged through the through hole 19 on the filter top cover 21. When replacing and cleaning the filter plate 22, first remove the top cover 16 and the filter top cover 21 in sequence. Then, by lifting the displacement rod 25, the displacement rod 25 drives the connecting sleeve 24 to move. After the connecting sleeve 24 moves, it drives the filter plate 22 to move upward, thereby disassembling the filter plate 22.

[0028] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
