Description

Technical Field

[0001] The utility model relates to the technical field of plate heat exchangers, in particular to a plate cleaning device for plate heat exchangers. Background Art

[0002] The plate heat exchanger is a high-efficiency heat exchanger made of stacked plates. It uses the channels formed between various plates to allow the two fluids to flow separately and exchanges heat through the plates. It has a relatively high heat exchange efficiency and low heat loss. It is widely used in the polyurethane production process.

[0003] The surface structure of the plate is relatively complex. For example, the herringbone corrugated plate and the straight corrugated plate contain more corrugations or grooves, which easily lead to fluid residue and make it difficult to clean the plate. There is a lack of corresponding automated equipment for cleaning the plate, and most of the cleaning is done manually. Manual cleaning of the plate is time-consuming and labor-intensive, and needs to be improved. Utility Model Content

[0015] Combine the following Figure 1~Figure 2 The technical solution of the utility model is further illustrated by specific embodiments.

[0016] like Figure 1 The plate cleaning device for a plate heat exchanger shown in the figure comprises: a cleaning tank 1, a draining tank 2, a lifting seat 7, a first slide 11, a second slide 12 and a first synchronous belt 10. The draining tank 2 is arranged on one side of the cleaning tank 1, and has a compact structure, which is convenient for draining and drying the plate 3 after cleaning. In this embodiment, an ultrasonic generator 4 is arranged in the cleaning tank 1, which can perform ultrasonic cleaning of the plate 3 to improve the cleaning effect.

[0017] The lifting seat 7 is suspended above the cleaning tank 1 and the draining tank 2. In order to drive the lifting seat 7 up and down, as shown in FIG. Figure 1 and Figure 2As shown, in this embodiment, a stand 6 is provided on one side of the cleaning pool, a second synchronous belt 16 is vertically provided on the stand 6, a third guide rail 15 is vertically provided on the stand 6 and is located on one side of the second synchronous belt 16, a slider 17 is provided on the third guide rail 15, a mounting seat 14 connected to the slider 17 is provided at one end of the lifting seat 7, and the lifting and lowering of the lifting seat 7 is guided by the third guide rail 15. A clamping plate 18 connected to the mounting seat 14 or the slider 17 is provided on the second synchronous belt 16, so that the lifting and lowering drive of the lifting seat 7 by the second synchronous belt 16 is realized. The second synchronous belt 16 is driven by a servo motor and controlled by a PLC to realize manual or automatic lifting and lowering control of the lifting seat 7.

[0018] The first slide 11 is laterally movably arranged below the lifting seat 7, and a first guide rail 13 corresponding to the first slide 11 is horizontally arranged at the bottom of the lifting seat 7 to guide the lateral movement of the first slide 11. The second slide 12 is laterally movably arranged below the lifting seat 7, and a second guide rail corresponding to the second slide 12 is horizontally arranged at the bottom of the lifting seat 7 to guide the lateral movement of the second slide 12.

[0019] In this embodiment, the second guide rail is parallel to the first guide rail 13, and the first guide rail 13 is located in front of the second guide rail. Therefore, the first slide 11 and the second slide 12 move laterally on different guide rails without affecting each other.

[0020] like Figure 1 As shown, the first synchronous belt 10 is horizontally arranged on the lifting seat 7 and parallel to the first guide rail 13, the front side of the first synchronous belt 10 is provided with a first bent plate 9 connected to the first slide 11, and the rear side of the first synchronous belt 10 is provided with a second bent plate 8 connected to the second slide 12, so as to realize reverse synchronization of the first slide 11 and the second slide 12.

[0021] In this embodiment, a motor 19 for driving the first synchronous belt 10 is provided on the lifting seat 7. The motor 19 can be intermittently reversed through a PLC controller to realize intermittent reciprocating motion of the first synchronous belt 10, and switch the first slide 11 and the second slide 12 between the cleaning tank 1 and the drain tank 2.

[0022] Plate hangers 5 are provided at the bottom of the first slide 11 and the second slide 12, respectively, to hang the plate 3. In the present embodiment, the plate hangers include two hooks, respectively, which cooperate with the two through holes on the plate 3 to improve the hanging stability of the plate 3. In the present embodiment, the height of the drain tank 2 is less than the height of the cleaning tank 1, as shown in Figure 1, so that two plates can be cleaned and drained at the same time without affecting each other, and the drain tank 2 is located at a low position, which is conducive to the replacement of the plate 3 above the drain tank 2 and reduces the labor intensity. Figure 1As shown, after the plate 3 is replaced, the lifting seat 7 is raised, and after the first slide 11 and the second slide 12 are switched horizontally, the lifting seat 7 descends, and the plate enters the cleaning tank 1 for cleaning. The cleaned plate is transferred to the draining tank 2 for draining, with a high degree of automation.
