Description

Technical Field

[0001] This utility model relates to the field of zinc roasting sand production technology, and in particular to a flue gas treatment device for zinc roasting sand production. Background Technology

[0002] Zinc calcined ore is a product obtained by roasting zinc concentrate. It mainly contains zinc oxide, zinc sulfate, and zinc sulfide, and is primarily used in zinc smelting. It is the most important raw material for zinc refining, and market demand mainly comes from zinc smelters as a raw material for zinc production. The production of zinc calcined ore generates gases containing many harmful substances, thus requiring frequent treatment of the flue gas.

[0003] Chinese patent document CN209101830U discloses a flue gas desulfurization and cooling system for producing zinc calcinate, comprising a shell, a fixing frame fixedly connected to the outside of the shell, support legs welded to the outside of the fixing frame, a base fixedly connected to the outside of the support legs, a fixing nut welded to the top of the base, a fixing screw internally threaded into the fixing nut, and an air inlet pipe fixedly connected to the top of the shell. This flue gas desulfurization and cooling system for producing zinc calcinate cools the gas first through cooling fins inside the gas collecting pipe. The cooled gas then enters the interior of the shell through an inner outlet. The cooling water inside the pipe comes into direct contact with the gas, causing a rapid drop in gas temperature, thus avoiding the temperature range for dioxin re-synthesis and preventing dioxin regeneration.

[0004] The aforementioned patent documents can avoid the temperature range of dioxin resynthesis during implementation, thereby preventing the regeneration of dioxins. However, they cannot easily and efficiently clean the filter screen, causing particulate matter in the flue gas to easily clog the filter screen, resulting in a reduction in the efficiency of flue gas purification. Utility Model Content

[0005] The main purpose of this invention is to provide a flue gas treatment device for zinc calcination production, which can effectively solve the problem of not being able to clean the filter screen conveniently and efficiently.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A flue gas treatment device for zinc calcination production includes a fume hood, a gas supply pipe fixedly connected to the upper end of the outer surface of the fume hood, a housing fixedly connected to the right side of the gas supply pipe, a gas dispersion mechanism fixedly connected to the left side of the housing, and the middle position of the left side of the gas dispersion mechanism fixedly connected to the right side of the gas supply pipe, an exhaust port fixedly connected to the middle of the right end of the outer surface of the housing, a plurality of limiting mechanisms fixedly connected at intervals to the bottom wall of the inner cavity of the housing, a filter assembly slidably connected to the upper part of each of the limiting mechanisms, a plurality of bearing mechanisms fixedly connected at intervals to the upper end of the outer surface of the fume hood, cleaning mechanisms symmetrically and movably connected to the left and right sides of each of the bearing mechanisms, and a locking mechanism fixedly connected to the side of each cleaning mechanism away from the middle of the corresponding bearing mechanism.

[0010] Preferably, the filter assembly includes a filter screen housing, a limiting plate is fixedly connected to the upper end of the outer surface of the filter screen housing, and the outer surface of the filter screen housing and the corresponding inner cavity of the clamping groove are slidably connected.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] like Figure 1As shown, a flue gas treatment device for zinc calcination production includes a fume hood 1. A gas supply pipe 2 is fixedly connected to the upper part of the outer surface of the fume hood 1. A housing 3 is fixedly connected to the right side of the gas supply pipe 2. A gas dispersion mechanism 4 is fixedly connected to the left side of the housing 3, which enables the flue gas to be evenly sprayed into the inner cavity of the housing 3. The middle position of the left side of the gas dispersion mechanism 4 is fixedly connected to the right side of the gas supply pipe 2. An exhaust port 5 is fixedly connected to the middle of the right end of the outer surface of the housing 3. Several limiting mechanisms 6 are fixedly connected at intervals to the bottom wall of the inner cavity of the housing 3, which can guide and limit the movement of the filter assembly 7. The upper part of the 6 is slidably connected to a filter component 7, which can fully filter particulate matter and other impurities in the flue gas. Several supporting mechanisms 8 are fixedly connected at intervals on the upper part of the outer surface of the fume hood 1, which can support the two corresponding cleaning mechanisms 9. The left and right sides of the supporting mechanisms 8 are symmetrically connected to the cleaning mechanisms 9, which can clean the surface of the filter component 7. The side of the cleaning mechanism 9 away from the middle of the corresponding supporting mechanism 8 is fixedly connected to a locking mechanism 10, which can lock the position of the corresponding cleaning mechanism 9.

[0024] To ensure that the flue gas is evenly ejected into the inner cavity of chamber 3, please refer to... Figure 2 The gas dispersing mechanism 4 includes a gas collecting box 41. Several gas dispersing ports 42 that communicate with the outside are distributed at intervals on the right end of the outer surface of the gas collecting box 41. This allows the gas to be evenly discharged into the left part of the inner cavity of the box 3. The middle part of the left end of the outer surface of the gas collecting box 41 is fixedly connected to the right end of the outer surface of the gas supply pipe 2.

[0025] To achieve the purpose of guiding and limiting the movement of filter component 7, see [reference needed]. Figure 2 The limiting mechanism 6 includes a limiting frame 61. The inner surface of the limiting frame 61 is provided with a clamping groove 62 that communicates with the outside, which can facilitate the accommodation and limiting of the corresponding filter screen housing 71.

[0026] To achieve the goal of fully filtering particulate matter and other impurities in flue gas, please refer to... Figure 2 The filter assembly 7 includes a filter screen housing 71, which can fully filter particulate impurities in the flue gas. A limiting plate 72 is fixedly connected to the upper end of the outer surface of the filter screen housing 71, and the outer surface of the filter screen housing 71 and the inner cavity of the corresponding clamping groove 62 are slidably connected.

[0027] To achieve the purpose of supporting the two corresponding cleaning mechanisms 9, see [reference] Figure 3The supporting mechanism 8 includes a supporting frame 81. The front and rear ends of the outer surface of the supporting frame 81 are symmetrically provided with positioning holes 82 that communicate with the outside. These holes can be used to fix the position of the U-shaped plate 101 in conjunction with the corresponding fastening screws 102. The left and right ends of the outer surface of the supporting frame 81 are symmetrically provided with rectangular through grooves 83 that communicate with the outside. These grooves facilitate the disassembly and assembly of the transmission plate 91 and the cleaning brush 92.

[0028] To achieve the purpose of cleaning the surface of filter assembly 7, please refer to... Figure 3 The cleaning mechanism 9 includes a transmission plate 91. A cleaning brush 92 is fixedly connected to one end of the outer surface of the transmission plate 91 near the middle of the inner cavity of the support frame 81. The lower ends of the outer surfaces of the transmission plate 91 and the cleaning brush 92 are slidably connected to the bottom wall of the inner cavity of the support frame 81.

[0029] When the limiting plate 72 is pulled, the filter screen housing 71 slides upward along the inner cavity of the corresponding clamping groove 62. The left and right ends of the outer surface of the filter screen housing 71 will be cleaned by the corresponding two sets of cleaning brushes 92, so that the particles blocked on the outer surface of the limiting plate 72 can be cleaned.

[0030] To achieve the goal of locking the position of the corresponding cleaning mechanism 9, refer to... Figure 4 The locking mechanism 10 includes a U-shaped plate 101, with fastening screws 102 symmetrically threaded to the front and rear ends of the outer surface of the U-shaped plate 101, and the inner surface of the U-shaped plate 101 is fixedly connected to the outer surface of the corresponding transmission plate 91.

[0031] When the cleaning brush 92 needs to be replaced or cleaned, unscrew the two fastening screws 102 from the inner cavity of the corresponding positioning hole 82, and then pull the U-shaped plate 101 to remove the corresponding transmission plate 91 and cleaning brush 92 from the inner cavity of the support frame 81.

[0032] The working principle of this utility model is as follows: When external smoke is collected by the smoke hood 1 and transported to the inner cavity of the gas collection box 41 along the inner cavity of the gas supply pipe 2, the smoke in the inner cavity of the gas collection box 41 will be evenly sprayed out from the openings of several gas outlets 42 under the pressure of the subsequent smoke into the left part of the inner cavity of the box 3. Then, it can be fully filtered by the filter screens installed inside the filter screen housings 71. When the filter screens inside the filter screen housings 71 become clogged with a large amount of particulate matter after filtering the smoke for a long time, the limit plate 72 can be used to pull it. As the filter moves upward, the filter screen installed inside the filter screen housing 71, which slides upward along the middle of the inner cavity of the support frame 81, will be swept by two sets of cleaning brushes 92 at its left and right ends. This allows for quick cleaning of particulate impurities attached to the surface of the filter screen. When it is necessary to replace or clean several sets of cleaning brushes 92, several fastening screws 102 are turned to rotate them out of the inner cavity of the corresponding positioning holes 82. At this time, by pulling the U-shaped plate 101, the transmission plate 91 and the cleaning brushes 92 can be slid out of the inner cavity of the corresponding support frame 81.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
