Description

Technical Field

[0001] The utility model relates to the technical field of combustion heat exchange equipment, in particular to combustion heat exchange equipment in a hot acid furnace area. Background Art

[0002] The hot acid furnace area usually refers to the area used for heat treatment and pickling of metal materials in the metal processing industry. These areas are equipped with special equipment, such as annealing furnaces, pickling tanks, etc., which are used to improve the physical properties and surface quality of metals. Combustion heat exchange equipment is a type of equipment used to recover heat energy. They are usually installed in the flue gas exhaust duct of the combustion equipment, and transfer the heat energy in the flue gas to the air or other fluids through the heat exchange process. The design and application of this equipment vary depending on different industrial processes, but their basic working principles are similar, that is, to achieve heat exchange between flue gas and air through the heat transfer surface.

[0003] An air-to-smoke heat exchanger is generally installed in the flue gas exhaust duct of the annealing furnace. The air-to-smoke heat exchanger is a common combustion heat exchange equipment, which can be used to recover heat energy in industrial flue gas and transfer it to the air flow. This equipment usually contains metal tube bundles, plate fins or spiral coils as heat transfer surfaces. When in use, air is sucked into the heat exchanger through a fan or blower to exchange heat with the flue gas, and then used for heating, drying or other industrial processes. The currently existing combustion heat exchange equipment can achieve heat exchange between air and flue gas.

[0004] However, since air or flue gas is introduced into the heat exchanger through a fan or blower, a filter is generally installed at the air inlet of the combustion heat exchange equipment to filter the air or flue gas to prevent impurities from affecting the heat exchange process. At the same time, in order to ensure the normal operation of the combustion heat exchange equipment, the filter needs to be frequently replaced and cleaned to ensure the heat exchange effect. The currently available combustion heat exchange equipment does not have a quick-disassembly structure, so each replacement and cleaning of the filter takes a long time, causing the combustion heat exchange equipment to be shut down for too long, thereby reducing the working efficiency of the combustion heat exchange equipment. Therefore, a hot acid furnace area combustion heat exchange equipment is proposed to solve the above-mentioned problems. Utility Model Content

[0005] In view of the deficiencies in the prior art, the utility model provides a combustion heat exchange device for a hot acid furnace area, which solves the problem that the existing combustion heat exchange equipment does not have a quick-disassembly structure, resulting in a long time spent on replacing the filter each time, causing the combustion heat exchange equipment to be shut down for too long, thereby reducing the working efficiency of the combustion heat exchange equipment.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: A combustion heat exchange device for a hot acid furnace area, comprising an air-smoke heat exchanger, a filter frame and a bottom plate, wherein a quick-release structure is arranged on the outside of the air-smoke heat exchanger;

[0007] The quick-release structure includes a positioning frame fixedly connected to the left side of the air-to-smoke heat exchanger, a sleeve fixedly connected to the side of the positioning frame, a sleeve rod and a spring fixedly connected to the inner side of the sleeve, a movable plate fixedly connected to the right side of the spring, a piston rod fixedly connected to the right side of the movable plate with one end passing through the sleeve and extending to the outside thereof, a piston block fixedly connected to the end of the piston rod away from the sleeve, a positioning groove is provided on the outer surface of the filter frame, a pull rod fixedly connected to the left side of the movable plate with one end passing through the sleeve and extending to the outside thereof, a mounting plate fixedly connected to the end of the pull rod away from the sleeve, and a handle fixedly connected to the left side of the mounting plate.

[0008] Furthermore, the number of the sleeve and the number of the positioning groove are both two, and both are relatively distributed on the left side of the air-to-gas heat exchanger.

[0009] Furthermore, a strip hole is opened on the left side of the positioning frame, and a filter is fixedly connected to the inner side of the filter frame.

[0010] Furthermore, the outer diameter of the piston block is smaller than the inner diameter of the positioning groove, the filter screen frame is made of aluminum alloy, and the positioning frame is made of stainless steel.

[0011] Furthermore, the front and back sides of the bottom plate are fixedly connected with articulated frames, and the front and back sides of the air-smoke heat exchanger are fixedly connected with positioning blocks.

[0012] Furthermore, a clamping ring is hinged on the inner side of the articulated frame, and the clamping ring is clamped with the positioning block.

[0013] Furthermore, threaded holes are provided on the left and right sides of the clamping ring and the positioning block, and fixing bolts are connected to the internal threads of the threaded holes.

[0014] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0015] The hot acid furnace area combustion heat exchange equipment realizes the function of quickly disassembling and assembling the filter frame by setting a quick-disassembly structure. Compared with the currently available combustion heat exchange equipment, it takes less time to replace and clean the filter, thereby avoiding the situation where the air-to-gas heat exchanger is shut down for too long, and effectively improving the working efficiency of the combustion heat exchange equipment.

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1 , Figure 2 , Figure 4 , Figure 5 and Figure 6 In this embodiment, a combustion heat exchange device for a hot acid furnace area includes an air-smoke heat exchanger 1, a filter frame 2 and a bottom plate 3. A quick-release structure is provided on the outside of the air-smoke heat exchanger 1;

[0025] The quick-release structure includes a positioning frame 4 fixedly connected to the left side of the air-smoke heat exchanger 1, a sleeve 5 is fixedly connected to the side of the positioning frame 4, a sleeve rod 6 and a spring 7 are fixedly connected to the inner side of the sleeve 5, a moving plate 8 is fixedly connected to the right side of the spring 7, a piston rod 9 is fixedly connected to the right side of the moving plate 8, one end of which penetrates the sleeve 5 and extends to the outside thereof, and a piston block 10 is fixedly connected to the end of the piston rod 9 away from the sleeve 5. A positioning groove 11 is provided on the outer surface of the filter frame 2, and a pull rod 12 is fixedly connected to the left side of the moving plate 8, one end of which penetrates the sleeve 5 and extends to the outside thereof, and the end of the pull rod 12 away from the sleeve 5 is fixedly connected to the mounting plate 13, and a handle 14 is fixedly connected to the left side of the mounting plate 13. By setting the quick-release structure, the function of quickly disassembling and assembling the filter frame 2 is realized. Compared with the existing combustion heat exchange equipment, the time spent on replacing and cleaning the filter is shorter, thereby avoiding the situation where the air-smoke heat exchanger 1 is shut down for too long, and effectively improving the working efficiency of the combustion heat exchange equipment.

[0026] Among them, when the filter frame 2 needs to be disassembled, the staff first needs to hold the handle 14 with one hand and pull it outward continuously, thereby pulling the movable plate 8 through the pull rod 12, so that the left side of the movable plate 8 continuously squeezes the spring 7, and drives the piston block 10 away from the positioning groove 11 through the piston rod 9, thereby releasing the limit on the filter frame 2. At this time, the staff pushes the filter frame 2 with the other hand, and can directly push the filter frame 2 out from the inner side of the positioning frame 4 to clean the filter.

[0027] In addition, when the filter screen frame 2 needs to be installed, the staff first needs to align the filter screen frame 2 with the inner side of the positioning frame 4 and insert it. After inserting it a short distance, pull the handle 14 outward to make the piston block 10 away from the left side of the air-smoke heat exchanger 1. At this time, you can continue to push the filter screen frame 2 until the filter screen of the filter screen frame 2 completely covers the air-smoke heat exchanger 1. When the position of the piston block 10 coincides with the positioning groove 11, release the handle 14. At this time, under the resetting action of the spring 7, the spring 7 will push the piston rod 9 and the piston block 10 to insert into the inner side of the positioning groove 11 through the movable plate 8, and then re-limit the filter screen frame 2 to filter the air or smoke.

[0028] It should be noted that there are two sleeves 5 and two positioning grooves 11 , and both are relatively distributed on the left side of the air-smoke heat exchanger 1 . A strip hole 15 is opened on the left side of the positioning frame 4 , and a filter is fixedly connected to the inner side of the filter frame 2 .

[0029] It should be understood that the outer diameter of the piston block 10 is smaller than the inner diameter of the positioning groove 11 , the filter screen frame 2 is made of aluminum alloy, and the positioning frame 4 is made of stainless steel.

[0030] See also Figure 1 and Figure 3The front and back sides of the bottom plate 3 are fixedly connected with an articulated frame 16, and the front and back sides of the air-to-gas heat exchanger 1 are fixedly connected with a positioning block 18. A clamping ring 17 is hinged on the inner side of the articulated frame 16, and the clamping ring 17 is clamped with the positioning block 18. Threaded holes 19 are provided on the left and right sides of the clamping ring 17 and the positioning block 18. The internal threads of the threaded holes 19 are connected with fixing bolts 20. Through the cooperation of the articulated frame 16, the clamping ring 17, the positioning block 18, the threaded holes 19 and the fixing bolts 20, the bottom plate 3 can be connected to the air-to-gas heat exchanger 1, thereby enhancing the stability of the air-to-gas heat exchanger 1, reducing the probability of tipping over, and thus ensuring safety.

[0031] The working principle of the above embodiment is:

[0032] When it is necessary to disassemble the filter frame 2, the staff first needs to hold the handle 14 with one hand and pull it outward continuously, thereby pulling the movable plate 8 through the pull rod 12, so that the left side of the movable plate 8 continuously squeezes the spring 7, and drives the piston block 10 away from the positioning groove 11 through the piston rod 9, thereby releasing the limit of the filter frame 2. At this time, the staff pushes the filter frame 2 with the other hand, and can directly push the filter frame 2 out from the inner side of the positioning frame 4 to clean the filter. In addition, when it is necessary to install the filter frame 2, the staff first needs to align the filter frame 2 with the positioning frame 4. Insert it into the inner side of the positioning frame 4. After it is inserted for a short distance, pull the handle 14 outward to make the piston block 10 away from the left side of the air-smoke heat exchanger 1. At this time, you can continue to push the filter frame 2 until the filter of the filter frame 2 completely covers the air-smoke heat exchanger 1. When the position of the piston block 10 coincides with the positioning groove 11, release the handle 14. At this time, under the resetting action of the spring 7, the spring 7 will push the piston rod 9 and the piston block 10 to the inner side of the positioning groove 11 through the moving plate 8, thereby re-limiting the filter frame 2 to filter air or smoke.
