Description

Technical Field

[0001] The utility model relates to the technical field of demisting, in particular to a demisting mechanism for preparing ammonium sulfate crystals. Background Art

[0002] In the preparation process of ammonium sulfate crystals, due to chemical reactions and changes in conditions, some misty or gaseous substances will be produced. If these substances are not treated, they will seriously affect the quality and output of ammonium sulfate crystals. In order to ensure the quality of ammonium sulfate crystals, a demisting mechanism needs to be introduced in the production process of ammonium sulfate crystals to remove these impurities. The demisting equipment that can be used to remove this impurity is mainly divided into: cold mist demister: using the principle of condensation, the misty or gaseous substances are condensed into liquid or solid, so as to be removed. This method is suitable for those substances that are easy to condense; adsorption demister: using the adsorption effect of adsorbents (such as activated carbon, silica gel, etc.) to adsorb misty or gaseous substances on the surface of the adsorbent, so as to achieve the purpose of removal. This method is suitable for those substances that are not easy to condense but can be adsorbed; and chemical demister: using the principle of chemical reaction, misty or gaseous substances are converted into harmless or easy-to-handle substances. This method is suitable for those substances that need to be removed by chemical reactions.

[0003] However, the cold mist demister has the problem that if it is used in a radioactive environment, its service life will be affected. Patent number CN110538551A, which is called a radioactive hot air condensation demister, solves the above problem by connecting a small amount of radioactive wastewater formed during the condensation process to the wastewater system through a side pipe to avoid contaminating the circulating cooling water.

[0004] However, these cold mist demisters are installed inside the pipes for transmitting exhaust gas. When too many impurities are accumulated inside the pipes over time, they can only be cleaned by flushing mechanisms, and the cleaning effect is poor. Therefore, it does not meet the existing needs. We propose a mist demister for preparing ammonium sulfate crystals. Utility Model Content

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] The metal tube 1 (model 304), the condensing demister 2 (model HL-008) and the spring 11 (model JX110) mentioned in the utility model can be purchased from the market or obtained by private customization.

[0024] See also Figures 1 to 4 The utility model provides an embodiment: a demisting mechanism for preparing ammonium sulfate crystals, comprising a metal tube 1, characterized in that a demisting device installation groove 22 is provided in the middle position inside the metal tube 1, a condensing demisting device 2 is provided inside the demisting device installation groove 22, and the upper and lower end surfaces of the condensing demisting device 2 are respectively in contact with the inner wall of the demisting device installation groove 22;

[0025] A hollow metal shell 3 communicating with the interior of the demister mounting groove 22 is fixedly installed on one side of the outer surface of the metal tube 1, a through opening B23 is provided on one side of the upper end surface of the hollow metal shell 3, a metal cover 4 is provided inside the through opening B23, a through opening A5 is provided on one side of the lower end surface of the hollow metal shell 3, and a moving mechanism is connected to the outer side of the condensation demister 2, and the condensation demister 2 can be moved forward and backward by the moving mechanism.

[0026] The moving mechanism includes a manual rotating shaft 6, and a transmission rotating shaft 7 is provided on both sides of the manual rotating shaft 6. The two transmission rotating shafts 7 and a manual rotating shaft 6 are connected in series through a synchronous chain 8. When the condensing defogger 2 needs to be cleaned, the manual rotating shaft 6 is manually rotated. When the manual rotating shaft 6 rotates, the two transmission rotating shafts 7 connected in series with it through the synchronous chain 8 will rotate synchronously.

[0027] The rear end face of the transmission shaft 7 is fixedly connected with a threaded rod 9, one side of the outer surface of the threaded rod 9 is sleeved with an internal thread sleeve 13 matching its external thread, one side of the internal thread sleeve 13 is provided with a metal rod 10, the front and rear end faces of the metal rod 10 are fixed with a fixed block, and the surface of the fixed block facing the condensation demister 2 is fixed to the condensation demister 2; the outer surface of the metal rod 10 is sleeved with a spring 11, one end of the spring 11 is connected to a metal sleeve 12 movably sleeved on the outer surface of the metal rod 10, and the front end face of the metal sleeve 12 is fixed to the spring 11. The rear end face of the metal sleeve 12 is connected to the fixing block fixed to the rear end face of the metal rod 10, and the surface of the metal sleeve 12 facing the internal thread sleeve 13 is fixed to the internal thread sleeve 13; when the transmission shaft 7 rotates, the threaded rod 9 fixed thereto will also rotate accordingly. Since the internal thread sleeve 13 sleeved on the outer surface of the threaded rod 9 is fixed to the metal sleeve 12 sleeved on the outer surface of the metal rod 10, the internal thread sleeve 13 itself cannot rotate. When the threaded rod 9 rotates, the internal thread sleeve 13 which is threadedly connected thereto but cannot rotate by itself will As the outer surface of the threaded rod 9 moves back and forth, the metal sleeve 12 fixed to the internal threaded sleeve 13 will also move along with it during the movement. When the condensing demister 2 needs to be cleaned, the metal sleeve 12 is moved backward. Since the rear end face of the metal sleeve 12 is connected to the fixed block fixed to the rear end face of the metal rod 10, as the metal sleeve 12 moves, the fixed block connected to it, the metal rod 10 fixed to the fixed block, and the condensing demister 2 will be driven to move backward together. When the rear end face of the condensing demister 2 contacts the inner wall of the hollow metal shell 3 and it can no longer move backward, the condensing demister 2 can be directly exposed to the outside world by removing the metal cover 4 located inside the opening B23. At this time, the cleaning personnel can use the cleaning device to manually clean the outer surface of the equipment directly. In the cleaning process, the water source used will be discharged through the opening A5 located on the lower end face of the hollow metal shell 3. Through the above technical solution, the cleaning personnel can directly clean the equipment, thereby improving the cleaning effect of the condensing demister 2.

[0028] A push rod 14 is fixedly provided on one side of the front end surface of the metal sleeve 12, and a rectangular block 15 is provided on one side of the push rod 14, and the surface of the push rod 14 facing the rectangular block 15 and the surface of the rectangular block 15 facing the push rod 14 are both inclined surfaces; when the condensing defogger 2 is cleaned, the manual rotating shaft 6 is rotated in the opposite direction to move the metal sleeve 12 forward. Since the front end surface of the metal sleeve 12 is connected to the spring 11, the spring force of the spring 11 itself can ensure that the metal sleeve 12 will not move when the position of the metal rod 10 moves, and the condensing defogger 2 is driven to move forward together. When the front end surface of the condensing defogger 2 contacts the inner wall of the defogger mounting groove 22, and the condensing defogger 2 itself can no longer move forward, the metal sleeve 12 will move forward on the outer surface of the metal rod 10 and squeeze the spring 11. During the movement of the metal sleeve 12, the push rod 14 fixed thereto will also move accordingly. When the metal sleeve 12 moves forward on the outer surface of the metal rod 10, the push rod 14 will contact the rectangular block 15 and push the rectangular block 15 inward.

[0029] A short rod 19 is provided on one side of the rectangular block 15, and a reset spring 21 is sleeved on the outer surface of the short rod 19. One end of the reset spring 21 is connected to a reset ring 20 that is movably sleeved on the outer surface of the rectangular block 15, and the reset ring 20 is fixed between the surface facing the rectangular block 15 and the rectangular block 15; a fixing plate 16 is fixedly provided on both sides of the front end surface of the condensing demister 2, and a fixing groove 17 is provided on both sides of the surface of the fixing plate 16 facing the rectangular block 15, and a fixing rod 18 is fixedly provided on the outer surface of the rectangular block 15 at a position corresponding to the fixing groove 17; when the rectangular block 15 moves inward, the reset ring 20 fixed thereto will also move with it. As the rectangular block 15 moves, the reset ring 20 will squeeze the reset spring 21 connected to it when it moves inward, and as the rectangular block 15 moves, the fixing rod 18 fixed to the outer surface of the rectangular block 15 will be inserted into the fixing groove 17 on the outer surface of the fixing plate 16 fixed to the condensing demister 2. When the fixing rod 18 is inserted into the fixing groove 17, the fixing plate 16 and the condensing demister 2 fixed thereto are fixed. The above technical solution can fix the condensing demister 2 and prevent it from moving without authorization due to the external environment, thereby ensuring the stability of the condensing demister 2 when it is in use.

[0030] When the condensing defogger 2 is in a fixed environment and needs to be moved backward, the manual rotating shaft 6 is rotated to drive the metal sleeve 12 to move backward. As the metal sleeve 12 moves at this time, the squeezed spring 11 will gradually stretch out, and the push rod 14 fixed to the metal sleeve 12 will also move backward when the metal sleeve 12 moves backward. As the push rod 14 moves, the rectangular block 15 can be gradually pushed back to its original position through the reaction force of the squeezed return spring 21. As the rectangular block 15 moves, the fixing rod 18 fixed to the outer surface of the rectangular block 15 will also gradually move out from the inside of the fixing groove 17. When the fixing rod 18 completely leaves the inside of the fixing groove 17, the fixation of the condensing defogger 2 is released.

[0031] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
