Description

Technical Field

[0001] This utility model relates to the field of heat exchanger technology, specifically a chemical heat exchanger structure. Background Technology

[0002] Chemical heat exchangers are key equipment used for heat transfer in chemical production processes. Their main function is to exchange heat between different fluids. Existing chemical heat exchangers use filtration and speed-up mechanisms to accelerate the airflow in the inlet of the heat exchanger and filter the external airflow. This helps to extend the service life of the heat exchanger and increase the airflow velocity in the inlet. However, existing filtration structures can be blocked by filtered debris, resulting in poor air intake efficiency and affecting heat exchange.

[0003] To address the aforementioned issues, CN202122307520.5 discloses a "Heat Exchanger for Polypropylene Chemical Processes." This device uses a pusher plate to remove debris blocking the outer wall of the filter screen, thus cleaning the screen and ensuring it remains clean without affecting the ventilation of the inlet duct, thereby improving the heat exchanger's efficiency. However, this device still has certain drawbacks in practical use. For example, while it can clean debris from the top of the filter screen, some debris may become trapped in the filter pores and cannot be removed. Furthermore, since the filter screen is fixed inside the inlet duct, it cannot be replaced if damaged, thus affecting the filter's filtration efficiency. Utility Model Content

The unblocking assembly composed of the electric telescopic rod, the lifting plate, the unblocking rods and the fixing plate is used to unblock debris blocking the filter holes.

[0007] Optionally, a disassembly plate is installed on one side of the outer end of the filter plate. Two through holes are opened on one side of the outer end of the disassembly plate. Two threaded holes are opened on one side of the outer end of the air intake frame. Bolts that are threadedly connected to the threaded holes are provided inside the through holes. A disassembly port is opened on one side of the outer end of the air intake frame. Two vertical plates are installed inside the air intake frame. Sliding grooves are opened on the inner side of both vertical plates. Slider blocks are connected to both sides of the outer end of the filter plate.

Detailed Implementation

[0018] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0019] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0020] like Figures 1-7 As shown, a chemical heat exchanger structure includes: a heat exchanger body 1, an air inlet frame 101 connected to the top of the heat exchanger body 1, a filter plate 102 disposed inside the air inlet frame 101, a plurality of filter holes 103 opened on the top of the filter plate 102, a fan 104 installed inside the air inlet frame 101, and a dredging assembly disposed at the bottom of the filter plate 102 for dredging debris blocking the filter holes 103. The dredging assembly includes: an electric telescopic rod 2, a lifting plate 201, a dredging rod 202, and a fixing plate 203. A disassembly assembly is disposed on one side of the outer end of the filter plate 102 for disassembling and assembling the filter plate 102. The disassembly assembly includes: a disassembly plate 3, a through hole 301, a threaded hole 302, and a bolt 303.

[0021] The air intake frame 101 is equipped with an electric telescopic rod 2. A lifting plate 201 is installed on the top of the electric telescopic rod 2. Multiple unblocking rods 202 are connected to the top of the lifting plate 201. A fixing plate 203 is connected to the bottom of the electric telescopic rod 2. The two sides of the fixing plate 203 are connected to the air intake frame 101. When it is necessary to clean the debris blocking the filter hole 103, the electric telescopic rod 2 pushes the lifting plate 201 and the multiple unblocking rods 202 up and down until the top of the unblocking rod 202 protrudes through the filter hole 103 to the top of the lifting plate 201, thereby pushing the debris in the filter hole 103 to the top of the lifting plate 201. Thus, the debris in the filter hole 103 is cleaned, thereby ensuring the airflow effect of the filter hole 103. The fixing plate 203 is used to install the electric telescopic rod 2 inside the air intake frame 101.

[0022] The filter plate 102 is equipped with a disassembly plate 3 on one side of its outer end. The disassembly plate 3 has two through holes 301 on one side of its outer end, and the air intake frame 101 has two threaded holes 302 on one side of its outer end. The through holes 301 are fitted with bolts 303 that are threaded into the threaded holes 302. When the filter plate 102 needs to be disassembled, the bolts 303 are turned out from the threaded holes 302 and the through holes 301. At this time, the filter plate 102 can be pulled out from the air intake frame 101 through the disassembly plate 3. Therefore, the damaged filter plate 102 can be disassembled and replaced.

[0023] The intake frame 101 has a disassembly port 4 on one side of its outer end. Two vertical plates 401 are installed inside the intake frame 101. The inner side of each vertical plate 401 has a sliding groove 402. The filter plate 102 has sliders 403 connected to both sides of its outer end. When the filter plate 102 needs to be installed, the filter plate 102 is slid into the intake frame 101 from the disassembly port 4 until one side of the disassembly plate 3 abuts against the outer side of the intake frame 101. Then, one end of the bolt 303 is inserted into the through hole 301 and rotated into the threaded hole 302 to fix the position of the disassembly plate 3 and the filter plate 102. When the filter plate 102 is slid into the intake frame 101, the sliders 403 on both sides of the filter plate 102 will slide into the sliding grooves 402 respectively, and the sliding grooves 402 support the sliders 403 and the filter plate 102.

[0024] The vertical plate 401 is connected to a horizontal plate 5 on one side of its outer end, and the horizontal plate 5 is connected to a vertical plate 501 on one side of its outer end. The vertical plate 501 and the horizontal plate 5 are connected to the air inlet frame 101 on both the front and rear sides. When the device is used, the air outside the air inlet frame 101 is drawn into the air inlet frame 101 by the fan 104, and then the air is blocked by the filter plate 102. The air can pass through the filter hole 103 and normally enter the heat exchanger body 1 through the filter plate 102.

[0025] One of the upright plates 501 has a motor 6 installed on one side of its outer end. A lead screw 601 is driven to the outer end of the motor 6 via a motor shaft. A cleaning plate 602 is provided on the outer side of the lead screw 601. A lead screw hole 603 is provided on the outer end of the cleaning plate 602, which is threaded to the lead screw 601. When it is necessary to clean the debris on the top of the filter plate 102, the motor 6 drives the motor shaft to rotate the lead screw 601. The cleaning plate 602 moves laterally through the lead screw hole 603 as the lead screw 601 rotates. Therefore, the debris on the top of the filter plate 102 can be pushed to the collection port 7 by the cleaning plate 602, and then fall into the collection frame 703 through the collection port 7 and the guide frame 701.

[0026] The horizontal plate 5 has a collection port 7 at the top and a guide frame 701 at the bottom. The air intake frame 101 has slots 702 on both sides of its outer end. A collection frame 703 is installed inside the slots 702. Since the collection frame 703 is located inside the slots 702, it can slide out from inside the air intake frame 101 to clean the debris inside the collection frame 703.

[0027] Working principle: When using this device, the fan 104 draws air from outside the intake frame 101 into the intake frame 101, and then the filter plate 102 intercepts impurities in the air. The air can pass through the filter holes 103 and normally enter the heat exchanger body 1. When it is necessary to clean the impurities on the top of the filter plate 102, the motor 6 drives the motor shaft to rotate the lead screw 601. The cleaning plate 602 moves laterally through the lead screw hole 603 as the lead screw 601 rotates. Therefore, the cleaning plate 602 pushes the impurities on the top of the filter plate 102 to the collection port 7, and then through the collection port 7 and the guide frame 701 into the collection frame 703. When it is necessary to clean the debris clogging the filter holes 103, the lifting plate 201 and multiple unblocking rods 202 are pushed up and down by the electric telescopic rod 2 until the top of the unblocking rod 202 protrudes through the filter holes 103 to the top of the lifting plate 201, thereby pushing the debris in the filter holes 103 to the top of the lifting plate 201, thus cleaning the debris in the filter holes 103 and ensuring the ventilation effect of the filter holes 103. When it is necessary to disassemble the filter plate 102, the bolt 303 is turned out from the threaded hole 302 and the through hole 301. At this time, the filter plate 102 can be pulled out from the air inlet frame 101 through the disassembly plate 3, so that the damaged filter plate 102 can be disassembled and replaced.
