Specific embodiments

[0026] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] As Figure 1 shown, the present utility model provides a chemical industry heat exchanger, including a heat exchanger body 1, a connection component 3 is arranged below the outer surface of the heat exchanger body 1, an end cover 2 is arranged on the right side of the heat exchanger body 1, and a loading and unloading component 4 is arranged on the right side of the outer surface of the heat exchanger body 1;

[0028] The arrangement of the loading and unloading component 4 facilitates the installation and disassembly of the end cover 2. After disassembly, it is convenient to clean the scale inside the heat exchanger body 1. At the same time, the arrangement of the connection component 3 facilitates the adjustment of the angle of the heat exchanger body 1, which is convenient for the removal of the scale. The working principle of the heat exchanger body 1 is not described in detail in the existing technology.

[0029] As Figure 2 - Figure 3As shown, the loading and unloading assembly 4 includes a fixing ring 41 and a mounting ring 46. The inner side of the fixing ring 41 is fixedly connected to the outer surface of the end cover 2. Four slots are annularly arranged on the outer surface of the fixing ring 41, and the left and right sides of the inner walls of the four slots are communicated. Positioning blocks 42 are lapped inside the four slots. A connecting plate 43 is arranged inside the positioning block 42. The lower surface of the connecting plate 43 is fixedly connected to the inner wall of the slot. A sleeve 44 is fixedly connected to the left side of the end cover 2. An annular sealing rubber 45 is fixedly connected to the outer surface of the sleeve 44. The outer surfaces of the sleeve 44 and the annular sealing rubber 45 are inserted into the interior of the heat exchanger body 1, and the outer surface of the annular sealing rubber 45 is lapped and pressed against the inner wall of the heat exchanger body 1. A square opening 431 is opened above the right side of the connecting plate 43. Springs 432 are fixedly connected to the upper and lower sides of the left side of the inner wall of the square opening 431. The right ends of the springs 432 are fixedly connected to a blocking block 433. The outer surface of the blocking block 433 is slidably connected to the interior of the square opening 431. Two inclined surfaces are mirror-symmetrically arranged on the upper and lower sides of the right side of the blocking block 433, and a flat surface is arranged above the lower inclined surface;

[0030] By inserting the sleeve 44 and the annular sealing rubber 45 in the end cover 2 into the interior of the heat exchanger body 1, it is convenient to squeeze and contract the annular sealing rubber 45 during the insertion process, so that the contracted annular sealing rubber 45 is closely attached to the inner wall of the heat exchanger body 1, realizing the sealing effect after installation. And through the settings of the positioning block 42, the slot and the connecting plate 43, it is convenient to position the end cover 2. When disassembly is required, by pressing the blocking block 433, it is convenient to squeeze and contract the spring 432 so that the blocking block 433 contracts inside the square opening 431, and then by directly sliding the positioning block 42 outwards and separating it from the connecting plate 43, the disassembly operation is realized. On the contrary, by pressing the blocking block 433 to slide the positioning block 42 and enter the slot inside. Due to the setting of the connecting plate 43, it is convenient for positioning. By releasing the blocking block 433, the contracted spring 432 pushes the blocking block 433 to move, which is convenient for restricting the position of the positioning block 42. The inclined surface is arranged to facilitate the installation of the positioning block 42, and the flat surface is arranged to block and limit the positioning block 42.

[0031] As Figure 4 shown, a plate 434 is fixedly connected to the lower left side of the connecting plate 43. The left side of the plate 434 is fixedly connected to the right side of the mounting ring 46. A vertically through strip-shaped groove is opened on the upper surface of the positioning block 42.

The inner parts of the vertical groove 421 and the strip-shaped groove and the outer surfaces of the connecting plate 43 and the plate 434 are slidably connected;

[0032] By making the inner part of the vertical groove 421 slide on the outer surface of the plate 434 while the positioning block 42 slides, the installation or disassembly operation of the positioning block 42 is realized.

[0033] As Figure 5As shown in the figure, the connecting component 3 includes a base 31. On the right side of the upper surface of the base 31, a support seat 32 is fixedly connected. An arc surface is provided on the upper surface of the support seat 32, and the outer surface of the arc surface is lapped with the outer surface of the heat exchanger body 1. A chute 33 is provided on the left side of the upper surface of the base 31. On the left side of the upper surface of the base 31, a U-shaped frame one 34 is fixedly connected. The inner side of the U-shaped frame one 34 is slidably connected with a U-shaped frame two 35. The upper part of the opposite surfaces in the vertical direction of the U-shaped frame two 35 is movably connected with the outer surface of the heat exchanger body 1. Above the upper right side in the horizontal direction of the U-shaped frame two 35, a movable seat is fixedly connected. A push plate 36 is movably connected inside the movable seat. The lower part of the outer surface of the push plate 36 is movably connected with an L-shaped plate 37. The lower part of the outer surface of the L-shaped plate 37 is slidably connected with the inside of the chute 33. A lead screw 39 is threadedly connected through the middle part in the vertical direction of the L-shaped plate 37. A motor 38 is arranged at the right end of the lead screw 39. The right side of the motor 38 is fixedly connected with the left side of the support seat 32. The output shaft of the motor 38 is fixedly connected with the right end of the lead screw 39;

[0034] After disassembly and by starting the motor 38, the lead screw 39 is driven to rotate. Due to the rotation of the lead screw 39, the L-shaped plate 37 is driven to slide inside the chute 33, and the push plate 36 is driven to move, so as to facilitate the upward movement of the U-shaped frame two 35, realizing the angle adjustment of the heat exchanger body 1. At this time, the heat exchanger body 1 is in an inclined state, which is convenient for cleaning the scale inside the heat exchanger body 1, so that the scale is directly discharged. Prevent the motor 38 from reversing to drive the lead screw 39, so that the L-shaped plate 37, the push plate 36 and the U-shaped frame two 35 return to their original positions. The motor 38 is electrically connected through an electric wire power supply.

[0035] As Figure 6 shown, square blocks 351 are fixedly connected to both the front and rear lower sides in the vertical direction of the U-shaped frame two 35. Anti-detachment grooves 341 are provided on the opposite inner surfaces in the vertical direction of the U-shaped frame one 34. A rubber pad 342 is fixedly connected to the lower surface in the horizontal direction of the U-shaped frame one 34. The upper surface of the rubber pad 342 is lapped with the lower surface in the horizontal direction of the U-shaped frame two 35. The outer surface of the square block 351 is slidably connected with the inside of the anti-detachment groove 341;

[0036] When the U-shaped frame two 35 moves up and down, the outer surface of the square block 351 slides inside the anti-detachment groove 341, preventing the U-shaped frame two 35 and the U-shaped frame one 34 from detaching, so that it can only move up and down. The rubber pad 342 has a buffering performance after the U-shaped frame two 35 moves downward.

[0037] Next, the working principle of this chemical industry heat exchanger will be specifically described.

[0038] When disassembly is required, pressing the blocking block 433 facilitates the extrusion and contraction of the spring 432, causing the blocking block 433 to contract inside the square opening 431. Then, by directly sliding the positioning block 42 outwards and separating it from the connecting plate 43, and then removing the end cover 2 outwards, the disassembly operation is achieved, making the disassembly simple and convenient. After disassembly, starting the motor 38 drives the lead screw 39 to rotate. Due to the rotation of the lead screw 39, the L-shaped plate 37 and the pushing plate 36 are driven to move, causing the pushing plate 36 to move the U-shaped bracket two 35 upwards, achieving the angle adjustment of the heat exchanger body 1. At this time, the heat exchanger body 1 is in an inclined state, facilitating the cleaning of the scale inside the heat exchanger body 1, allowing the scale to be directly discharged.

[0039] The above has generally described the present utility model in detail. However, based on the present utility model, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, modifications or improvements made without departing from the spirit and idea of the present utility model are within the protection scope of the present utility model.
