Description

Technical Field

[0001] This utility model relates to the field of exhaust gas purification technology, specifically to an exhaust gas purification device for calcined gypsum. Background Technology

[0002] Gypsum is a very important building material with a huge application in the construction industry. The production of gypsum involves crushing and calcining the raw ore. The calcination process requires the use of a calcining furnace, which is a common high-temperature processing equipment that uses natural gas, oil or electricity as energy for iron smelting, rare metal recovery and chemical production. It is widely used in metallurgy, steel and chemical industries.

[0003] The calcination process generates a large amount of high-temperature exhaust gas, the main harmful components of which include toxic gases such as nitrogen oxides, sulfur dioxide, and non-methane hydrocarbons. In addition, the exhaust gas also contains a large amount of particulate impurities such as black ash. By setting up a filter screen in the filter box, impurities accumulate on the surface of the filter screen after a long period of filtration, which causes the filter screen to become clogged and affects the efficiency of exhaust gas discharge.

[0004] Therefore, we propose a gypsum calcination exhaust gas purification device to solve the problems mentioned above. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0027] Example 1

[0028] Please see Figure 1-8 A gypsum calcination exhaust gas purification device includes a calcination tank 1, a purification box 2 located on the other side of the calcination tank 1, a common conduit A connecting the calcination tank 1 and the purification box 2, an induced draft fan 6 located on the other side of the purification box 2 (the induced draft fan 6 can discharge the exhaust gas in the purification box 2), and a common conduit B connecting the purification box 2 and the induced draft fan 6. A fixing box 3 is fixedly installed near the middle of the top of the purification box 2, and an opening is opened on one side of the fixing box 3. A groove is opened at the top of the inner cavity of the opening. A disassembly component 7 is provided in the inner cavity of the fixing box 3. A knocking component 8 is provided in the inner cavity of the purification box 2. A filter screen 5 is movably inserted near one side of the top of the purification box 2 (the filter screen 5 can filter out a large amount of particulate impurities such as black ash in the exhaust gas). An activated carbon mesh 4 is movably inserted near the other side of the top of the purification box 2 (the activated carbon mesh 4 can purify the exhaust gas).

[0029] The striking assembly 8 includes a drive motor 81 located near the center of the rear side of the purification box 2 and a round rod 82 fixedly installed on the power output shaft end of the drive motor 81. The front end of the round rod 82 movably passes through the rear side of the inner cavity of the purification box 2 and is fixedly installed with an eccentric wheel 83. A T-shaped rack plate 84 is provided on one side of the eccentric wheel 83, and the bottom of the T-shaped rack plate 84 is slidably connected to the bottom of the inner cavity of the purification box 2. A rotating gear 85 is meshed on the top of the T-shaped rack plate 84 near one side. A crossbar 86 is provided through the center of the front side of the rotating gear 85, and several striking blocks 87 are fixedly sleeved on the outer periphery of the crossbar 86.

[0030] Specifically, when the filter screen 5 is struck, the striking component 8 can be used in conjunction with it to make the rotating gear 85 rotate in both directions, thereby moving the striking block 87, which is fixedly sleeved on the outer periphery of the crossbar 86, back and forth to strike the filter screen 5. This causes the surface of the filter screen 5 to vibrate and shake off the impurities on the filter screen 5, preventing the impurities from clogging the filter screen 5 and affecting the efficiency of subsequent exhaust gas purification.

[0031] Support plates 861 are rotatably connected to both ends of the crossbar 86, and the bottom of the support plates 861 is fixedly connected to the bottom of the inner cavity of the purification box 2. A support block 811 is fixedly installed at the bottom of the drive motor 81, and the front side of the support block 811 is fixedly connected to the purification box 2.

[0032] Specifically, the support plate 861 can support the crossbar 86, and the support block 811 can support the drive motor 81.

[0033] Connecting blocks 841 are fixedly installed on both the front and rear sides of the T-shaped rack plate 84, and a support telescopic rod 842 is fixedly installed on one side of each connecting block 841. An installation plate 843 is fixedly installed on the other end of each support telescopic rod 842. The top of each installation plate 843 is fixedly connected to the bottom of the inner cavity of the purification box 2. A support spring 844 is movably sleeved on the outer periphery of each installation plate 843, and the two ends of the support spring 844 are fixedly connected to the T-shaped rack plate 84 and the installation plate 843, respectively.

[0034] Specifically, by setting the support telescopic rod 842 and the support spring 844, the T-shaped rack plate 84 can be reset to its initial state when the eccentric wheel 83 is not in contact with the T-shaped rack plate 84.

[0035] A collection trough 21 is movably installed at the bottom of the purification box 2 near one side, and several positioning ports 22 are opened at the top of the purification box 2 near both sides.

[0036] Both activated carbon mesh 4 and filter mesh 5 have sealing gaskets 52 fixedly installed at their bottoms (both activated carbon mesh 4 and filter mesh 5 have T-shaped cross-sections). The slots 51 are opened on opposite sides near the top. Both activated carbon mesh 4 and filter mesh 5 have square blocks 53 fixedly installed at their bottoms. The bottom of the inner cavity of the purification box 2 has installation slots near both sides. The bottom of the square blocks 53 is movably inserted into the inner cavity of the adjacent installation slots. Both filter mesh 5 and activated carbon mesh 4 have several positioning blocks 54 fixedly installed at their bottoms. The positioning blocks 54 are movably inserted into the inner cavity of the adjacent positioning ports 22.

[0037] Specifically, by setting the sealing gasket 52, the sealing between the activated carbon mesh 4, the filter mesh 5 and the purification box 2 can be improved. By setting the block 53 to be inserted into the inner cavity of the installation groove, the stability of the installation of the activated carbon mesh 4 or the filter mesh 5 can be improved.

[0038] Example 2

[0039] This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 6 and Figure 8 The disassembly assembly 7 includes a fixing block 71 fixedly installed at the middle position of the bottom of the opening cavity and a reset telescopic rod 72 fixedly installed on the opposite side of the fixing block 71 near the front and rear sides. The ends of two adjacent reset telescopic rods 72 are fixedly installed with a locking block 73. (The locking block 73 and the activated carbon mesh 4 and filter screen 5 are all arc-shaped on both sides. During installation, the square block 53 fixed at the bottom of the activated carbon mesh 4 or filter screen 5 can be inserted into the cavity of the adjacent installation groove for installation.) The opposite side of the locking block 73 is movably inserted into the cavity of the adjacent locking groove 51. The outer periphery of the reset telescopic rod 72 is movably sleeved with a reset spring 74, and the two ends of the reset spring 74 are fixedly connected to the locking block 73 and the fixing block 71 respectively. The top of the locking block 73 is fixedly installed with a vertical rod 75. The top of the vertical rod 75 moves through the cavity of the groove and is fixedly installed with a handle 76.

[0040] Specifically, when the filter screen 5 or activated carbon screen 4 needs to be disassembled and replaced after long-term use, with the cooperation of the disassembly component 7, the adjacent handle 76 can be pushed to the opposite side, which can move the two locking blocks 73 to the opposite side, thereby moving the locking blocks 73 away from the inner cavity of the adjacent locking slot 51, making it convenient to disassemble and replace the filter screen 5 or activated carbon screen 4 and reducing the disassembly intensity for the staff.

[0041] A rectangular block 731 is fixedly installed on the bottom of the card block 73 near the front and rear sides. Two rectangular grooves 732 are opened on the bottom of the inner cavity of the opening near the front and rear sides. The two adjacent rectangular grooves 732 are arranged left and right. Two balls 733 are installed on the bottom of the rectangular block 731. Rolling grooves 734 are opened on the bottom of the inner cavity of the rectangular groove 732. The balls 733 are slidably connected in the inner cavity of the adjacent rectangular grooves 732.

[0042] Specifically, by setting the ball bearing 733 to move within the groove 734, the friction of the rectangular block 731 sliding within the rectangular groove 732 can be reduced, thus reducing the disassembly effort for workers.

[0043] Working Principle: In use, exhaust gas enters the inner cavity of the purification box 2 through duct A. Impurities in the exhaust gas are filtered through filter screen 5 and activated carbon screen 4. During filtration, the drive motor 81 can be started via an external controller. The rotation of the drive motor 81's power output shaft causes the round rod 82 fixed to the end of the drive motor 81's power output shaft to rotate, which in turn causes the eccentric wheel 83 fixed to the end of the round rod 82 to rotate. This allows the T-shaped rack plate 84 to reciprocate under the cooperation of the connecting block 841, the support telescopic rod 842, the mounting plate 843, and the support spring 844. This causes the rotating gear 85 to rotate clockwise and counterclockwise. The striking block 87 fixedly sleeved on the crossbar 86 prevents... Continuously tapping the filter screen 5 can cause vibration on its surface and shake off impurities, preventing them from clogging the filter screen 5 and affecting the efficiency of subsequent exhaust gas purification. When it is necessary to replace the activated carbon screen 4 or the filter screen 5, the adjacent handle 76 can be pushed to the opposite side. With the connection of the adjacent uprights 75, the adjacent locking block 73 can be moved to the opposite side, thereby moving the locking block 73 away from the inner cavity of the adjacent locking slot 51. This releases the restriction on the activated carbon screen 4 and the filter screen 5, allowing them to be directly removed from the inner cavity of the purification box 2 for replacement. This facilitates the disassembly and replacement of the filter screen 5 or the activated carbon screen 4, reducing the disassembly effort for the staff.

[0044] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
