Description

Technical Field

[0001] This invention relates to the technical field of evaporator anti-clogging, specifically to an evaporator anti-clogging structure that facilitates the installation and removal of salt leg sleeves. Background Technology

[0002] An evaporator is a heat exchanger that transfers heat from the process fluid to the refrigerant, causing a phase change. It is a crucial component of the four main refrigeration systems. Low-temperature condensed liquid passes through the evaporator, exchanging heat with the outside air, vaporizing and absorbing heat to achieve a cooling effect. An evaporator mainly consists of a heating chamber and an evaporation chamber. The heating chamber provides the heat needed for evaporation, causing the liquid to boil and vaporize. The evaporation chamber completely separates the gas and liquid phases. Through the evaporator, heat exchange with the outside air occurs, liquefying and absorbing heat to achieve a cooling effect. Evaporators are widely used. However, during operation, because moisture is separated during discharge, other media are prone to blockages, leading to high repair costs. Therefore, anti-blockage mechanisms are necessary.

[0003] However, the commonly used evaporator anti-clogging structure that facilitates the installation and removal of salt leg sleeves still has the following shortcomings:

[0004] 1. The existing anti-clogging structure for evaporators that facilitates the installation and removal of salt leg sleeves is inconvenient for quick and easy docking and installation between the mechanism and the evaporator in actual use, or the stability and tightness of the connection between the anti-clogging mechanism and the evaporator are not high.

[0005] 2. The existing anti-clogging structure of the evaporator, which facilitates the installation and removal of the salt leg sleeve, is not convenient for breaking up the blockage inside the sleeve. Moreover, under long-term use, the blockage tends to adhere to the inside of the sleeve, making cleaning difficult.

[0006] 3. The existing evaporator anti-clogging structure, which facilitates the installation and removal of salt leg sleeves, does not have a backflushing mechanism. Under long-term use, there is still a risk of pipe blockage, and the overall sealing performance is poor, making it prone to leakage.

[0007] Therefore, we propose an evaporator anti-clogging structure that facilitates the installation and removal of the salt leg sleeve, in order to solve the problems mentioned above. Summary of the Invention

[0008] The purpose of this invention is to provide an evaporator anti-clogging structure that facilitates the installation and removal of the salt leg sleeve, thereby solving the problems mentioned in the background art, such as the inconvenience of quickly and easily connecting the anti-clogging mechanism to the evaporator during actual use, the low stability and tightness of the connection between the anti-clogging mechanism and the evaporator, the difficulty in dispersing blockages inside the sleeve, the tendency for blockages to adhere to the inside of the sleeve during long-term use, the difficulty in cleaning, the lack of a backflushing mechanism, the risk of pipe blockage during long-term use, and the poor overall sealing performance, which is prone to leakage.

Through the setting of the connecting cylinder, valve and sealing mechanism, the discharge zigzag sleeve can be backwashed at regular intervals. The discharge backflow enters from the bottom of the salt leg and discharges from the upper side of the salt leg, forming a small internal circulation between the discharge pump and the salt leg.

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Please see Figure 1-11This invention provides a technical solution: an evaporator anti-clogging structure that facilitates the installation and removal of the salt leg sleeve, comprising an evaporator body 1, an evaporator sleeve 2, a discharge folding sleeve 3, a first sealing ring 4, a docking mechanism 5, a fixing column 6, a fixing plate 7, a movable plate 8, a movable frame 9, a connecting column 10, a connecting plate 11, a fixing cap 12, a connecting bracket 13, a crushing frame 14, a scraper 15, a servo motor 16, a bevel gear 17, a timer 18, a connecting cylinder 19, a valve 20, a sealing mechanism 21, a movable column 22, a sealing plate 23, a second sealing ring 24, a third sealing ring 25, a support plate 26, a movable rod 27, a positioning block 28, a mounting column 29, a spring 30, an auxiliary block 31, and an auxiliary plate 32.

[0046] When using this evaporator anti-clogging structure that facilitates the installation and removal of the salt leg sleeve, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, an evaporator sleeve 2 is fixedly connected to the left side of the evaporator body 1. First, the discharge zigzag sleeve 3 is inserted and installed in the middle of the evaporator sleeve 2. A first sealing ring 4 is fitted at the connection between the discharge zigzag sleeve 3 and the evaporator sleeve 2 to ensure the sealing of the connection and prevent leakage. Combined with the setting of the docking mechanism 5, the docking mechanism 5 is set at an equal angle on the outside of the evaporator sleeve 2. The docking mechanism 5 includes a fixed post 6 fixedly connected to the outer side of the discharge zigzag sleeve 3, a fixed plate 7 fixedly connected to the outside of the evaporator sleeve 2, a movable plate 8 sleeved on the outside of the fixed plate 7, and a movable frame 9 for limiting the position. The discharge zigzag sleeve 3 drives the fixed post 6 to connect with the evaporator sleeve 2 through a slot. Then, by flipping the movable frame 9, the movable frame 9 and the movable plate 8 rotate. The movable frame 9 is sleeved on the outside of the fixed post 6.

[0047] Then, pull the movable plate 8 towards the side closer to the evaporator body 1. The movable plate 8 slides between itself and the fixed plate 7, and the movable plate 8 drives the connecting column 10 to slide in the middle of the connecting plate 11. The movable plate 8 drives the movable frame 9 to engage with the fixed column 6, thus facilitating the fixing of the fixed column 6 and the evaporator sleeve 2, and facilitating the connection and limiting of the discharge folding sleeve 3 and the evaporator sleeve 2. Then, by rotating the fixing cap 12 threaded onto the outer surface of the connecting column 10, the fixing cap 12 is fitted against the side of the connecting plate 11, thus facilitating the limiting of the connection between the connecting column 10 and the connecting plate 11, and fixing the fixed plate 7 and the movable plate 8, preventing the movable frame 9 from loosening and ensuring good fastening. After installation, during discharge, if... Figure 2As shown, a servo motor 16 installed at the lower end of the discharge folding sleeve 3 can be started. The output end of the servo motor 16 is connected to the crushing frame 14 through a bevel gear 17. The bevel gear 17 drives the crushing frame 14 to rotate with the connecting bracket 13. The crushing frame 14 can crush the blockages in the conveying process to prevent blockage. Moreover, scrapers 15 are fixedly connected to both ends of the crushing frame 14. The crushing frame 14 drives the scrapers 15 to rotate in the discharge folding sleeve 3. The scrapers 15 are set close to the inner wall of the discharge folding sleeve 3, which facilitates the scraping of the blockages attached to the inner wall of the discharge folding sleeve 3, and further maintains the smooth flow of the conveying.

[0048] Furthermore, during discharge, by raising the liquid level difference between the separator and the heater (not shown in the diagram), material vaporization in the heater tubes is prevented from the source, thus preventing blockage. A high-speed circulation discharge design can also be adopted to keep the crystal slurry flowing at high speed in the discharge pipe, thereby reducing the residence time of the crystal slurry in the pipe. Excellent insulation measures are also provided to minimize the cooling and crystallization of the crystal slurry in the pipe, reducing the chance of pipe blockage. At the same time, 45° elbows can be used for high-concentration pipes, placing the thickener in the closest position to the separator, minimizing the length of high-concentration pipes, further reducing the chance of pipe blockage. Through reasonable pipe layout and wiring, the number of elbows used is minimized, effectively preventing pipe blockage.

[0049] like Figure 2 , Figure 8 , Figure 9 , Figure 10 and Figure 11 As shown, timer 18 is used for timing operation. After the time is conveyed at one end, the set time is reached. The upper end of the discharge folding sleeve 3 is fixedly connected to the connecting cylinder 19, and the connecting cylinder 19 is connected to the external water source through valve 20. Combined with the setting of the sealing mechanism 21, the sealing mechanism 21 includes a movable column 22 for connection, a sealing plate 23 fixedly connected to the lower end of the movable column 22, a second sealing ring 24 fixedly connected to the upper end of the sealing plate 23, and a third sealing ring 25 fixedly connected to the upper end of the movable column 22. By pulling the auxiliary plate 32 upward, the auxiliary plate 32 drives the auxiliary block 31 to slide between the auxiliary block 31 and the mounting column 29. The auxiliary block 31 squeezes the spring 30, causing the spring 30 to undergo elastic deformation.

[0050] At this point, the auxiliary plate 32 disengages from the upper end of the movable rod 27, thereby releasing the limit between the movable rod 27 and the support plate 26. Then, the movable rod 27 is pulled outward, and it slides on the upper end of the support plate 26. The movable rod 27 drives the positioning block 28 to move, causing the positioning block 28 to disengage from the lower end of the movable column 22, thereby releasing the limit between the movable column 22 and the connecting cylinder 19. Then, the movable column 22 is pressed down, and it slides between the movable column 22 and the connecting cylinder 19. The movable column 22 drives the sealing plate 23 to move downward, and the second sealing ring 24 disengages from the discharge folding sleeve 3, thereby releasing the seal at the connection between the discharge folding sleeve 3 and the connecting cylinder 19. When the movable column 22 drives the sealing plate 23 to move to the discharge point... When the bottom of the folded sleeve 3 is reached, the movable column 22 drives the third sealing ring 25 to fit against the upper end of the connecting cylinder 19, sealing the connection between the movable column 22 and the connecting cylinder 19 to prevent leakage. Then, the movable rod 27 is pushed inward, causing the movable rod 27 to engage with the positioning block 28 at the upper end of the movable column 22, limiting the distance between the movable column 22 and the connecting cylinder 19. Then, the auxiliary plate 32 is released, and the spring 30 returns to its elastic deformation, causing the auxiliary block 31 to slide between the auxiliary plate 32 and the mounting column 29, so that the auxiliary block 31 engages with the auxiliary plate 32 and the movable rod 27, thereby facilitating the limitation between the movable rod 27 and the support plate 26 and preventing the positioning block 28 from becoming loose from the movable column 22.

[0051] Then, open valve 20 connected to connecting cylinder 19. At this time, external water source is pumped through an external water pump (not shown in the figure) into the discharge zigzag sleeve 3 through valve 20 and connecting cylinder 19 to backwash the discharge zigzag sleeve 3. This allows the discharge backflow to enter from the bottom of the salt leg and discharge from the upper side of the salt leg, forming a small internal circulation between the discharge pump and the salt leg. This prevents large lumps of salt from forming inside the salt leg, which would cause blockage. This ensures less or no pipe blockage and is highly practical. After backwashing, the above operation is reversed, and the sealing plate 23 is then sealed between connecting cylinder 19 and discharge zigzag sleeve 3. The overall structure is simple, easy to operate, and very convenient to use.
