Description

Technical Field

[0001] This utility model relates to the field of plate heat exchanger technology, and in particular to a plate heat exchanger with a filter collection device. Background Technology

[0002] Plate heat exchangers are highly efficient heat exchange devices widely used in industries such as chemical, pharmaceutical, food, HVAC (heating, ventilation and air conditioning), and refrigeration. They are mainly composed of a series of parallel metal plates, with fluid channels formed between these plates, through which heat is transferred between the fluids.

[0003] However, existing plate heat exchangers do not have internal filtration structures, but after long-term use, internal cleaning is required, which increases maintenance costs. On the other hand, some plate heat exchangers with filtration structures usually require the device to be stopped for maintenance, which is inconvenient and affects the user experience, thus reducing the efficiency of the device. Therefore, these problems need to be solved. Utility Model Content

Two drain pipes are fixedly connected to the surface of the heat exchanger body, and both drain pipes communicate with the interior of the heat exchanger body. Two fixed boxes are fixedly connected to the surface of the heat exchanger body, and inlet pipes are fixedly connected to the top of each of the two fixed boxes. Connecting frames are slidably connected inside each of the two fixed boxes, and a sliding mechanism for the sliding connecting frames is provided inside each of the two fixed boxes. A filtration mechanism is provided inside each of the two connecting frames. Through the setting of the filter barrel, the input end of the device can be filtered. At the same time, the connecting frames can be slidable, which facilitates the replacement of the filter barrel. Moreover, the device can continue to supply liquid while the filter barrel is being replaced, thereby improving the performance of the device.

Each of the two fixed boxes is provided with a filter chamber, and both filter chambers are located on top of the two connecting chambers and are connected to the interior of the two connecting chambers, so as to connect the liquid inlet pipe with the interior of the heat exchanger body.

[0008] As a further embodiment of this utility model, the sliding mechanism includes a slider. Two limiting grooves are horizontally formed inside the filter chamber, and limiting blocks are slidably connected inside each of the two limiting grooves. Both limiting blocks are fixedly connected to the surface of the connecting frame. A connecting rod is vertically fixedly connected to the bottom of the connecting frame, and a slider is fixedly connected to the bottom end of the connecting rod. A control chamber is horizontally formed inside the fixed box, and the connecting rod and slider are slidably connected inside the control chamber. A lead screw is rotatably connected inside the control chamber, and the lead screw is horizontally positioned. The slider is slidably fitted onto the surface of the lead screw, and the slider cooperates with the lead screw. A knob is rotatably connected to one end of the fixed box surface, and the knob is fixedly connected to one end of the lead screw for rotating the lead screw. Through the cooperation of the slider, the connecting frame can slide outwards.

A connecting port is opened at the bottom of the filter chamber, and the connecting port is connected to the inside of the connecting chamber. A baffle is fixedly connected to the end of the connecting frame away from the knob for installing the filter bucket, thereby filtering the inside of the fixed box.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. During use, the filter can be set up to filter the input end of the device, and the connecting frame can be slid to facilitate the replacement of the filter can. At the same time, the device can continue to transport materials while the filter is being replaced, thereby improving the device's performance.

At the same time, the connecting frame 3 can be slid, which facilitates the replacement of the filter barrel 4. Moreover, the device can continuously supply while replacing the filter barrel 4, thereby improving the performance of the device.

[0020] Reference Figure 1 and Figure 2 In a preferred embodiment, each of the two fixed boxes 2 is provided with a connecting chamber 23, and both connecting chambers 23 are connected to the interior of the heat exchanger body 1. Each of the two fixed boxes 2 is provided with a filter chamber 22, and both filter chambers 22 are located on top of the two connecting chambers 23 and are connected to the interior of the two connecting chambers 23, so as to connect the liquid inlet pipe 21 with the interior of the heat exchanger body 1.

[0021] Reference Figure 2 and Figure 4In a preferred embodiment, the sliding mechanism includes a slider 36. Two horizontally opening limiting grooves 25 are formed inside the filter chamber 22. Limiting blocks 32 are slidably connected inside each of the two limiting grooves 25. Both limiting blocks 32 are fixedly connected to the surface of the connecting frame 3. A connecting rod 35 is vertically fixedly connected to the bottom of the connecting frame 3. A slider 36 is fixedly connected to the bottom end of the connecting rod 35. A control chamber 24 is horizontally formed inside the fixing box 2. The connecting rod 35 and slider 36 are slidably connected inside the control chamber 24. A lead screw 51 is rotatably connected inside the control chamber 24. The lead screw 51 is horizontally positioned. The slider 36 is slidably fitted onto the surface of the lead screw 51, and the slider 36 cooperates with the lead screw 51. A knob 5 is rotatably connected to one end of the surface of the fixing box 2. The knob 5 is fixedly connected to one end of the lead screw 51 and is used to rotate the lead screw 51. Through the cooperation of the slider 36, the connecting frame 3 can slide outwards.

[0022] Reference Figure 3 and Figure 4 In a preferred embodiment, the filtration mechanism includes a filter bucket 4. A placement groove 33 is vertically opened through the surface of the connecting frame 3. Two slots 34 are vertically opened on the arc surface inside the placement groove 33.

[0023] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: In actual use, the filter barrel 4 allows for filtration at the input end of the device, while the connecting frame 3 can slide, facilitating the replacement of the filter barrel 4. Furthermore, the device can continuously supply fluid while being replaced, thereby improving the device's performance. During use, hot and cold fluids can be introduced through the tops of the two inlet pipes 21. The fluid enters the fixed box 2 through the inlet pipes 21 and then passes through the connecting frame 3. At this point, the filter barrel 4 filters impurities from the fluid, which then passes through the connecting chamber 23. The fluid is drawn into the heat exchanger body 1, making the fluid cleaner. After prolonged use, the knob 5 can be manually turned to rotate the lead screw 51. With the cooperation of the slider 36, the connecting rod 35 and the connecting bracket 3 will slide outward, and the filter barrel 4 will also slide outward. Through the setting of the baffle 31, after the filter barrel 4 slides out of the filter chamber 22, the inside of the fixing box 2 can be sealed, so that the fluid can be transported normally and continuously. Then the filter barrel 4 can be replaced through the connecting port 26 set inside the filter chamber 22. After completion, the connecting bracket 3 can be slid into the filter chamber 22 again, so that it can be used continuously, thereby improving the efficiency of the device.
