Technical Field

[0001] The utility model relates to the technical field of heat exchangers, in particular to an anti-clogging plate heat exchanger. Background Art

[0002] Plate heat exchanger is a commonly used heat exchange equipment used to transfer heat between different fluids. It is a high-efficiency heat exchanger composed of a series of stacked metal sheets with a certain corrugated shape. Thin rectangular channels are formed between various plates, and heat is exchanged through the plates. When the heat exchange medium contains large particles or fibrous substances, it is easy to block the channels between the plates.

[0003] The Chinese patent "A plate heat exchanger with an anti-clogging structure" authorization announcement number "CN216977621U" uses the cooperation of the first filter screen and the second filter screen to filter the impurities contained in the hot liquid entering the first cavity and the cold liquid entering the second cavity, thereby achieving the effect of filtering impurities and preventing the plates from being blocked. When the first filter screen and the second filter screen need to be cleaned, the staff disassembles the box body and the filter box, removes the filter plate inserted in the socket in the filter box, and cleans the first filter screen and the second filter screen installed in the filter plate for subsequent use.

[0004] Although the first filter screen and the second filter screen can be cleaned in the above scheme, the box body and the filter box need to be disassembled in turn before the filter plate can be taken out for cleaning, which is cumbersome and increases the labor intensity of the staff.

[0005] Therefore, an anti-clogging plate heat exchanger is proposed to solve the above problems. Utility Model Content

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: an anti-clogging plate heat exchanger, comprising: a plate heat exchanger body, an inlet of the plate heat exchanger body is installed with a mounting tube, and a disassembly mechanism and a sealing mechanism are arranged inside the mounting tube; wherein the disassembly mechanism comprises a filter plate arranged inside the mounting tube, one end of the filter plate is provided with an annular groove, the inner wall of the mounting tube is slidably connected with a fixing ring, the fixing ring is clamped with the annular groove, and one end of the fixing ring is provided with a driving assembly.

Under the action of the trigger ball and the trigger rod, the fixing ring is pushed into the annular groove to complete the clamping connection, and the installation of the filter plate can be completed. When the filter plate is disassembled and cleaned, the threaded rod is rotated in the opposite direction to release the squeeze of the trigger ball on the trigger rod. Under the action of the spring, the fixing ring will automatically reset and release the clamping connection with the annular groove, thereby releasing the fixation of the filter plate. At the same time, when the fixing ring is reset, the sealing mechanism automatically releases the seal of the filter plate. At this time, just pull the filter plate upwards to take it out. The operation is simple, which reduces the workload of the staff and saves manpower and material resources.

[0009] Preferably, the sealing mechanism includes two annular airbags embedded and installed on the inner wall of the mounting tube, the inner wall of the mounting tube is fixedly connected with an air storage ring, the inner wall of the air storage ring is slidably connected with an extrusion plate, one end of the extrusion plate is fixedly connected with a connecting rod, and a connecting tube is provided between the annular airbag and the air storage ring. When installing the filter plate, the sealing mechanism is synchronously driven by the movement of the fixed ring, so that the gas in the air storage ring enters the two annular airbags at the same time, and the annular airbags are expanded to seal the connection between the filter plate and the mounting tube, thereby strengthening the sealing between the filter plate and the mounting tube and ensuring the stability of the fluid when passing through the filter plate.

[0010] Preferably, the connecting pipe is a three-way pipe, one end of which is connected to the annular airbag, and the other two ends of which are respectively connected to corresponding annular airbags, which is conducive to allowing the gas in the gas storage ring to enter the two annular airbags at the same time.

[0013] Preferably, the second cylinder is connected to the first cylinder, and one end of the trigger rod is bent into a spherical shape, which is conducive to the surface of the trigger ball to better contact with the end of the trigger rod and push the trigger rod to move.

[0014] Preferably, a pull rod is fixedly connected to the upper end of the surface of the filter plate, which is conducive to the staff to better pull the filter plate to move.

[0015] The beneficial effects of the utility model are:

Under the action of the trigger ball and the trigger rod, push the fixing ring into the annular groove to complete the clamping connection. The installation of the filter plate can be completed. When the filter plate is disassembled and cleaned, the threaded rod is rotated in the opposite direction to release the extrusion of the trigger ball on the trigger rod. Under the action of the spring, the fixing ring will automatically reset and release the clamping connection with the annular groove, thereby releasing the fixation of the filter plate. At the same time, when the fixing ring is reset, the sealing mechanism automatically releases the seal of the filter plate. At this time, the filter plate can be pulled up to take it out. The operation is simple, which reduces the work intensity of the staff and saves manpower and material resources.

[0017] 2. When installing the filter plate, the sealing mechanism is driven to operate synchronously by moving the fixed ring, so that the gas in the gas storage ring enters the two annular airbags at the same time, and the annular airbags expand to seal the connection between the filter plate and the installation tube, thereby strengthening the sealing between the filter plate and the installation tube and ensuring the stability of the fluid when passing through the filter plate.

[0025] 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.

[0026] When implementing: Figure 1-6 As shown, an anti-clogging plate heat exchanger includes: a plate heat exchanger body 1, a mounting tube 2 is installed at the inlet of the plate heat exchanger body 1, and a disassembly mechanism 3 and a sealing mechanism 4 are arranged inside the mounting tube 2; wherein the disassembly mechanism 3 includes a filter plate 301 arranged inside the mounting tube 2, an annular groove 303 is opened at one end of the filter plate 301, a fixing ring 302 is slidably connected to the inner wall of the mounting tube 2, the fixing ring 302 is clamped with the annular groove 303, and a driving component 304 is arranged at one end of the fixing ring 302.

[0027] When the plate heat exchanger body 1 is in operation, the fluid enters the installation pipe 2 through the pipeline, and the pipeline is connected to the installation pipe 2 through a flange.

[0028] like Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the driving assembly 304 includes a first cylinder 3041 fixedly connected to the inner wall of the mounting tube 2, a threaded rod 3042 is rotatably connected to the inner wall of the first cylinder 3041, and a trigger ball 3043 is threadedly connected to the surface of the threaded rod 3042. A second cylinder 3044 is fixedly connected to the lower end of the surface of the first cylinder 3041, a circular plate 3045 is slidably connected to the inner wall of the second cylinder 3044, a spring 3047 is fixedly connected between one end of the circular plate 3045 and the inner wall of the second cylinder 3044, a trigger rod 3046 is fixedly connected to the inner wall of the circular plate 3045, one end of the trigger rod 3046 penetrates the interior of the first cylinder 3041, and the other end of the trigger rod 3046 penetrates the spring 3047 and the second cylinder 3044 in sequence and is fixedly connected to one end of the fixing ring 302. An arc groove 305 is opened on the surface of the mounting tube 2, and the shape of the arc groove 305 is half a circular ring. The second cylinder 3044 is connected to the first cylinder 3041 , and one end of the trigger rod 3046 is bent into a spherical shape.

[0029] When the device is needed to filter the fluid entering the plate heat exchanger body 1, the filter plate 301 is installed first. The width of the arc groove 305 is the same as the width of the filter plate 301, and the diameter of the arc groove 305 is the same as the diameter of the filter plate 301. When installing the filter plate 301, the filter plate 301 is inserted into the installation tube 2 through the arc groove 305. At this time, the lower end of the surface of the filter plate 301 is in contact with the inner wall of the installation tube 2, and the arc groove 305 and the fixing ring 302 are on the same horizontal plane. At this time, the threaded rod 3042 is rotated to move the trigger ball 3043 downward, and one end of the trigger rod 3046 extends to the bottom of the trigger ball 3043. When the trigger ball 3043 moves downward, it will contact the trigger rod The trigger rod 3046 contacts one end of the trigger ball 3043, and the trigger ball 3043 continues to move downward. At this time, the trigger ball 3043 will squeeze the trigger rod 3046, so that the trigger rod 3046 moves toward the end away from the trigger ball 3043. When the trigger rod 3046 moves, it drives the circular plate 3045 to move synchronously, and the spring 3047 is compressed. When the trigger rod 3046 moves, it will push the fixing ring 302 to move, so that the fixing ring 302 enters the annular groove 303 to fix the filter plate 301, and when the fixing ring 302 moves, it will drive the sealing mechanism 4 to operate to seal the filter plate 301 and the installation pipe 2. After the filter plate 301 is installed, the fluid entering the installation pipe 2 is filtered by the filter plate 301 and then enters the plate heat exchanger body 1.

[0030] like Figure 2 , Figure 3 , Figure 4 and Figure 6As shown, the sealing mechanism 4 includes two annular airbags 401 embedded and installed on the inner wall of the mounting tube 2, the inner wall of the mounting tube 2 is fixedly connected with an air storage ring 402, the inner wall of the air storage ring 402 is slidably connected with an extrusion plate 403, one end of the extrusion plate 403 is fixedly connected with a connecting rod 404, and a connecting pipe 405 is provided between the annular airbag 401 and the air storage ring 402. The connecting pipe 405 is a three-way pipe, one end of which is connected to the annular airbag 401, and the other two ends of the connecting pipe 405 are respectively connected to the corresponding annular airbags 401.

[0031] When the filter plate 301 enters the mounting tube 2, the two annular airbags 401 are respectively located at the two ends of the filter plate 301. When the driving assembly 304 runs to push the fixed ring 302 to move, the fixed ring 302 will drive the connecting rod 404 to move, so that the connecting rod 404 pushes the extrusion plate 403 to move and squeezes the gas in the gas storage ring 402. When the gas in the gas storage ring 402 is squeezed, the gas will enter the annular airbag 401 through the connecting tube 405, causing the annular airbag 401 to expand and fit with the filter plate 301, thereby completing the seal between the filter plate 301 and the mounting tube 2.

[0032] When the filter plate 301 needs to be disassembled and cleaned, the threaded rod 3042 is rotated in the opposite direction to drive the trigger ball 3043 to move upward. When the trigger ball 3043 moves upward, the squeezing of the trigger rod 3046 will be released. At this time, the trigger rod 3046 will be reset under the action of the spring 3047, thereby driving the fixing ring 302 to reset and release the clamping connection with the annular groove 303. At the same time, when the fixing ring 302 is reset, the squeezing plate 403 will be reset under the action of the connecting rod 404. At this time, the gas in the air storage ring 402 loses its squeezing, and the gas in the annular airbag 401 flows back into the air storage ring 402. The annular airbag 401 releases the seal on the filter plate 301. At this time, the filter plate 301 can be taken out by pulling it upward through the arc groove 305.

[0033] like Figure 5 As shown, the inner bottom wall of the first cylinder 3041 is fixedly connected to the limit rod 3048, the surface of the trigger ball 3043 is fixedly connected to the limit block 3049, and the inner wall of the limit block 3049 is slidably connected to the surface of the limit rod 3048. When the trigger ball 3043 moves, the limit block 3049 will move at the same time. At this time, under the action of the limit rod 3048, the limit block 3049 can only move in the vertical direction.

[0034] like Figure 3 As shown, a pull rod is fixedly connected to the upper end of the surface of the filter plate 301. When pulling the filter plate 301 to move upward, just pull the pull rod.

[0035] When the utility model is in use, when installing the filter plate 301, the filter plate 301 is inserted into the installation tube 2 through the arc groove 305, and the threaded rod 3042 is rotated to make the trigger ball 3043 move downward and contact one end of the trigger rod 3046. When the trigger ball 3043 continues to move downward, it will squeeze the trigger rod 3046, so that the trigger rod 3046 drives the circular plate 3045 to move toward the end away from the trigger ball 3043, the spring 3047 is compressed, and when the trigger rod 3046 moves, it will push the fixing ring 302 into the annular groove 303 to fix the filter plate 301. At the same time, the movement of the fixing ring 302 will drive the connecting rod 404 to move, and the connecting rod 404 pushes the squeezing plate 403 to squeeze the gas in the gas storage ring 402, and the gas enters the annular airbag 401 through the connecting tube 405, so that the annular airbag 401 expands and fits the filter plate 301, completing the sealing between the filter plate 301 and the installation tube 2, thereby completing the sealing and fixing of the filter plate 301.

[0036] When the filter plate 301 needs to be disassembled and cleaned, the threaded rod 3042 is rotated in the opposite direction to drive the trigger ball 3043 to move upward to release the squeezing of the trigger rod 3046. At this time, under the action of the spring 3047, the trigger rod 3046 drives the fixing ring 302 to reset and release the clamping connection with the annular groove 303, and under the action of the connecting rod 404, it will drive the squeezing plate 403 to reset, and the gas in the annular airbag 401 will flow back into the air storage ring 402, and the annular airbag 401 will release the seal on the filter plate 301. At this time, the filter plate 301 can be taken out by pulling it upward through the arc groove 305.

[0037] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
