Description

Technical Field

[0001] This utility model relates to the field of vacuum pumping device technology, specifically a catalyst vacuum pumping device for an aromatic hydrocarbon complex. Background Technology

[0002] In aromatics complexes, vacuuming the catalyst tank is a crucial process step. Traditionally, steam jet vacuum pumps are used for vacuuming; however, this method has several drawbacks. Steam jet vacuum pumps consume large amounts of steam, increasing energy costs and placing high demands on the steam supply system. Unstable steam supply can also affect the continuity of vacuuming operations. Therefore, using water ring vacuum pumps for vacuuming can save steam and reduce noise.

[0003] The prior art patent document CN112283110B provides a water ring vacuum pump, which, by setting screws, impeller, threaded cap and housing, makes it difficult for gaps to appear between the sealing plate and the impeller when the operator fixes the sealing plate to the impeller with screws.

[0004] The aforementioned existing technology, while enabling gas to be filtered through a filter plate upon entering the water ring vacuum pump, has shortcomings in the gas filtration process. This device relies on a filter plate for gas filtration and a cleaning brush to remove impurities from the filter plate. During operation, dust can easily pass through the filter plate's pores and enter the pump body, reducing its lifespan and efficiency. Therefore, the filter plate needs to be disassembled for cleaning. However, the disassembly process for the filter components is cumbersome and complex, making it difficult to easily remove and maintain the air-filtering components. Therefore, we need a catalyst vacuum pumping device for aromatic hydrocarbon complexes. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, a catalyst vacuuming device for an aromatic hydrocarbon complex includes a catalyst tank 1. A fixed pipe 2 is fixedly connected to the outer wall of the catalyst tank 1, and a mounting base 3 is fixedly connected to one end of the fixed pipe 2. An installation pipe 4 is fixedly connected to one end of the mounting base 3, and a flange connection end 5 is fixedly connected to the bottom of the installation pipe 4.

The adjustment component 7 includes a mounting shell 701, and a reduction motor 702 is installed on the top of the mounting shell 701. The output shaft of the reduction motor 702 is fixedly connected to a lead screw 703 via a coupling, and a movable frame 704 is threadedly connected to the outer wall of the lead screw 703. A guide rod 705 is slidably connected to the inner wall of the movable frame 704. A gate 706 is fixedly connected to one end of the frame 704, and a sealing ring 707 is provided on the inner wall of the gate 706; the filter assembly 8 includes a cover plate 801, a limit frame 802 is fixedly connected to the inner wall of the installation pipe 4, a slot 803 is opened on the inner wall of the cover plate 801, and a filter screen frame 804 is slidably connected to the inner wall of the slot 803, a slot 805 is opened on the inner wall of the filter screen frame 804, and a filter screen 806 is fixedly connected to the inner wall of the filter screen frame 804, a fixing block 807 is fixedly connected to the top of the cover plate 801, a sliding groove 808 is opened on the inner wall of the fixing block 807, a threaded groove 809 is opened on the inner wall of the fixing block 807, and a screw 810 is threadedly connected to the inner wall of the threaded groove 809, a locking block 811 is rotatably connected to one end of the screw 810, and an activated carbon filter screen 812 is provided on one side of the filter screen 806.

[0025] Through the above technical solution, the disassembly and installation of the filter frame 804 are simple. When cleaning or replacing the filter screen is required, the operator can quickly disassemble the filter frame 804 for easy cleaning and maintenance. By combining the filter screen 806 and the activated carbon filter screen 812, the gas extracted from the catalyst tank 1 can be doubly purified. Solid particles, dust and other impurities are intercepted by the filter screen 806, while the activated carbon filter screen 812 effectively adsorbs organic impurities and odors in the gas. The purified gas enters the water ring vacuum pump 6, reducing the damage of impurities to the pump body and extending the service life of the water ring vacuum pump 6, thus meeting people's needs. The gate 706 can be raised and lowered by the geared motor 702, thereby adjusting the opening of the gate 706 and facilitating the control of the gas flow. The structure is simple and easy to use. The sealing ring 707 enhances the sealing between the gate 706 and the mounting base 3, preventing gas leakage.

[0026] Specifically, the geared motor 702 forms a moving structure with the moving frame 704 via the lead screw 703, and one end of the lead screw 703 is threaded through the moving frame 704.

[0027] With the above technical solution, a bearing is provided at one end of the lead screw 703, and the bearing is fixed on the mounting base 3. A threaded groove is opened in the movable frame 704, and the thread in the threaded groove matches the thread on the lead screw 703. A circular groove is opened on the other side of the movable frame 704. The guide rod 705 is fixed in the mounting shell 701, and one end of the guide rod 705 passes through the circular groove to play a guiding role. This device is controlled by connecting an external controller.

[0028] Specifically, the shape and size of the outer wall of the gate 706 match the shape and size of the inner wall of the mounting base 3, and the outer wall of the gate 706 fits into the inner wall of the mounting base 3.

[0029] The above technical solution enhances the connection between the gate 706 and the mounting base 3, allowing the sealing ring 707 on the gate 706 to fit well against the mounting base 3, thus improving the sealing performance and preventing gas leakage.

[0030] Specifically, the cover plate 801 forms a sliding structure with the filter frame 804 through the slot 803, and the inner wall of the slot 803 is in contact with the outer wall of the filter frame 804.

[0031] The above technical solution facilitates the insertion of the filter frame 804 into the slot 803 for installation. The inner wall of the filter frame 804 is provided with a sealing rubber ring, which enhances the sealing between the filter frame 804 and the cover plate 801 and prevents gas leakage.

[0032] Specifically, the shape and size of the filter frame 804 match the shape and size of the limiting frame 802, and one end of the filter frame 804 extends into the limiting frame 802.

[0033] With the above technical solution, the filter frame 804 is inserted into the limiting frame 802, and the limiting frame 802 limits the filter frame 804, making the filter frame 804 more stable to be installed.

[0034] Specifically, the fixing block 807 forms a threaded structure with the screw 810 through the threaded groove 809, and one end of the screw 810 extends into the threaded groove 809 for connection.

[0035] Through the above technical solution, the thread in the threaded groove 809 matches the thread on the screw 810. One end of the screw 810 is provided with a handle, and the other end of the screw 810 is provided with a bearing, which is fixed in the locking block 811.

[0036] Specifically, the shape and size of the card block 811 match the shape and size of the card slot 805, and one end of the card block 811 extends into the card slot 805.

[0037] Through the above technical solution, the card block 811 moves one end into the card slot 805 of the filter frame 804 to fix the filter frame 804, prevent the filter frame 804 from loosening, and enhance stability.

[0038] In operation, the water ring vacuum pump 6 first operates, drawing gas from the catalyst tank 1 through a pipeline. When gas flow needs adjustment, the reduction motor 702 operates, driving the lead screw 703 to rotate, thus making the moving frame 704 move more stably on the guide rod 705. The movement of the moving frame 704 drives the gate 706 to move, adjusting the opening size for gas passage and controlling the gas flow. When the gas passes through the filter screen 806, the filter screen 806 filters and intercepts solid particles, dust, and other impurities. When the gas passes through the activated carbon filter screen 812, the activated carbon filter screen 812 effectively adsorbs organic impurities and odors in the gas. The gas purified by the secondary filtration enters the water ring vacuum pump 6. When cleaning or maintaining the filter screen 806 or the activated carbon filter screen 812, the operator rotates the screw 810 by the handle, causing the locking block 811 to move within the slide groove 808. One end of the locking block 811 moves from the filter screen 806 to the activated carbon filter screen 812. The filter screen frame 804 is removed from its slot 805. The operator can then pull the filter screen frame 804 out of its slot 803 in the cover plate 801 using a handle, completing the disassembly of the filter screen frame 804 and facilitating cleaning and maintenance of the filter screen on it. During installation, the operator inserts the filter screen frame 804 into the slot 803 in the cover plate 801. One end of the filter screen frame 804 extends into the limiting bracket 802 to enhance stability. The operator rotates the screw 810 using a handle, causing the locking block 811 to move. One end of the locking block 811 extends into the slot 805 of the filter screen frame 804, thus fixing the filter screen frame 804 in place. The installation and disassembly process of the filter screen frame 804 is simple and convenient, solving the problem of the difficulty in disassembling and cleaning the filter element used in the water ring vacuum pump 6 for gas filtration in existing technologies, thus meeting people's needs. This completes all the work. Content not described in detail in this specification belongs to prior art known to those skilled in the art.

[0039] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
