According to the embodiments of this utility model, the liquid tank achieves thorough mixing of the system and avoids crystallization through the stirring device, and the filtration device can absorb toxic and harmful gases generated in the system, while maintaining pressure balance between the liquid tank and the outside air, thus meeting the reaction or monitoring needs of systems that generate harmful gases or volatile liquids under normal pressure.

[0004] Regarding the above-mentioned issues, the following technical defects were found: the liquid tank in the existing technology does not have external heat insulation protection measures, which leads to poor heat insulation performance of the tank. As a result, additional heating and cooling devices are required to control the temperature of the tank, which increases energy waste.

[0005] Therefore, it is necessary to provide a new type of external thermal insulation and protection plate for liquid tanks to solve the above-mentioned technical problems. Utility Model Content

[0006] The purpose of this utility model is to overcome the shortcomings of the existing technology and propose an external heat insulation and protection plate for liquid tanks.

[0007] To solve the above technical problems, this utility model provides an external heat-insulating protective plate for a liquid tank, comprising: a tank body and a heat-insulating structure. The upper end of the tank body is fixedly connected to an inlet pipe, and the lower end of the tank body is fixedly connected to an outlet pipe. The heat-insulating structure is sleeved on the outside of the tank body and includes a lower heat-insulating cover, an upper heat-insulating cover, and a fixing base. The lower heat-insulating cover is sleeved on the outside of the tank body, and a plurality of support columns are fixedly connected to the lower end of the lower heat-insulating cover. The fixing base is fixed to the outer wall of the lower heat-insulating cover, and a rotating shaft is rotatably inserted through the inner wall of the fixing base. A connecting plate is fixedly connected to the arc surface of the rotating shaft, and a lead screw is slidably inserted through the surface of the short arm end of the connecting plate. The upper end of the lead screw rotates... The device is equipped with an ear plate, one side of which is fixedly connected to the outer wall of the upper insulation cover. A driven gear is threaded onto the arc surface of the lead screw. The upper surface of the driven gear is rotatably connected to the lower surface of the short arm end of the connecting plate.

A support plate is fixedly connected to the outer wall of the lower insulation cover. A cylinder is fixedly connected to the upper surface of the support plate. The output end of the cylinder is rotatably connected to one end of the connecting rod.

[0008] The effect achieved by the above components is as follows: by setting up an insulation structure, the upper and lower insulation covers can be automatically adjusted to insulate and protect the liquid tank during use, thereby optimizing the insulation performance of the liquid tank and reducing energy waste.

[0010] The effect achieved by the above components is that when the connecting plate drives the upper insulation cover to rotate, the slide rod fixed on the connecting plate will slide along the inner wall of the arc-shaped hole. Since the angle of the arc-shaped hole is limited, the rotation angle of the upper insulation cover can be limited.

[0011] Preferably, a positioning plate is fixedly connected to one side of the short arm end of the connecting plate, and a positioning rod is slidably passed through the surface of the positioning plate. One end of the short arm end of the positioning rod is fixedly connected to one side of the ear plate.

[0012] The effect achieved by the above components is that when the lead screw drives the ear plate and the upper insulation cover to move, the positioning rod fixed on one side of the ear plate will move through the surface of the positioning plate, thereby preventing the ear plate and the upper insulation cover from rotating or shifting during the movement process.

[0013] Preferably, a sealing ring is fixedly connected to the upper end of the lower insulation cover, and the sealing ring has a circular cross-section.

[0014] The effect achieved by the above components is that when the upper and lower insulation covers are connected, the sealing ring can improve the sealing performance between the upper and lower insulation covers.

[0015] Preferably, the lower insulation cover is provided with an auxiliary structure on its exterior.

[0016] The effect achieved by the above components is that, by setting up auxiliary structures and adjusting clamps, tanks of different sizes can be fixed inside the lower insulation cover, thereby improving the applicability of the insulation and protection plate.

[0018] The effect achieved by the above components is that the rubber pad can increase the friction on one side of the clamping plate, thereby improving the clamping plate's limiting effect on the tank.

[0019] Preferably, the outer wall of the lower insulation cover is fixedly connected with two limiting rings. The inner wall of the limiting ring is in contact with the arc surface of the threaded rod. A pressure rod is threaded through the outer wall of the limiting ring, and one end of the pressure rod abuts against the arc surface of the threaded rod.

[0020] The effect achieved by the above components is that after the clamping plate firmly holds the tank, the rotating pressure rod abuts against the arc surface of the threaded rod, which can lock the threaded rod and thus prevent the threaded rod from shaking.

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figure 1 and Figure 2 The present invention provides an external heat-insulating protective plate for a liquid tank, comprising: a tank body 1 and a heat-insulating structure 3, wherein the upper end of the tank body 1 is fixedly connected to a feed pipe 2 and the lower end of the tank body 1 is fixedly connected to a discharge pipe 5.

[0034] The insulation structure 3 is installed on the outside of the tank body 1, and the auxiliary structure 4 is provided on the outside of the lower insulation cover 301.

[0035] In the embodiments of this utility model, please refer to Figures 3 to 5The insulation structure 3 includes a lower insulation cover 301, an upper insulation cover 304, and a fixing base 305. The lower insulation cover 301 is fitted onto the outside of the tank body 1. Several support columns 302 are fixedly connected to the lower end of the lower insulation cover 301. The fixing base 305 is fixed to the outer wall of the lower insulation cover 301. A rotating shaft 306 is rotatably inserted through the inner wall of the fixing base 305. A connecting plate 307 is fixedly connected to the arc surface of the rotating shaft 306. A lead screw 308 is slidably inserted through the surface of the short arm end of the connecting plate 307. An ear plate 309 is rotatably connected to the upper end of the lead screw 308. One side of the ear plate 309 is fixedly connected to the outer wall of the upper insulation cover 304. A driven gear 3 is threadedly connected to the arc surface of the lead screw 308. 10. The upper surface of the driven gear 310 is rotatably connected to the lower surface of the short arm end of the connecting plate 307. A servo motor 311 is fixedly connected to the upper surface of the short arm end of the connecting plate 307. The output end of the servo motor 311 is fixedly connected to the driving gear 312, which meshes with the driven gear 310. A turntable 315 is fixedly connected to one end of the rotating shaft 306. A connecting rod 318 is rotatably connected to the centrifugal position of the turntable 315 away from the rotating shaft 306. A support plate 316 is fixedly connected to the outer wall of the lower insulation cover 301. A cylinder 317 is fixedly connected to the upper surface of the support plate 316. The output end of the cylinder 317 is rotatably connected to one end of the connecting rod 318. By setting the insulation structure 3, the upper insulation cover 304 and the lower insulation cover 301 can be automatically adjusted to insulate and protect the liquid tank during use, thereby optimizing the insulation performance of the liquid tank and reducing energy waste. An arc-shaped hole 319 is provided on the side of the fixed base 305 away from the turntable 315. The center of the arc-shaped hole 319 is coaxial with the axis of rotation of the connecting plate 307. A slide rod 320 is slidably connected to the inner wall of the arc-shaped hole 319. One end of the slide rod 320 is fixedly connected to one side of the connecting plate 307. The cross-section of the arc-shaped hole 319 is a half-circle arc. When the connecting plate 307 drives the upper insulation cover 304 to rotate, the slide rod 320 fixed on the connecting plate 307 will slide along the inner wall of the arc-shaped hole 319. Since the angle of the arc-shaped hole 319 is limited, the rotation angle of the upper insulation cover 304 can be limited. A positioning plate 313 is fixedly connected to one side of the short arm end of the connecting plate 307. A positioning rod 314 is slidably passed through the surface of the positioning plate 313. One end of the short arm end of the positioning rod 314 is fixedly connected to one side of the ear plate 309. When the lead screw 308 drives the ear plate 309 and the upper insulation cover 304 to move, the positioning rod 314 fixed on one side of the ear plate 309 will move through the surface of the positioning plate 313, thereby preventing rotational displacement of the ear plate 309 and the upper insulation cover 304 during their movement. A sealing ring 303 is fixedly connected to the upper end of the lower insulation cover 301, and the sealing ring 303 has an annular cross-section. When the upper insulation cover 304 and the lower insulation cover 301 are mated, the sealing ring 303 can improve the sealing performance between the upper insulation cover 304 and the lower insulation cover 301.

[0036] In the embodiments of this utility model, please refer to Figure 6The auxiliary structure 4 includes two threaded rods 41, which are threaded through the outer wall of the lower insulation cover 301. Each threaded rod 41 has a clamping plate 42 rotatably connected to its near end, and several rotating rods 43 are fixedly connected to the far ends of the two threaded rods 41. Several guide rods 47 slide through the outer wall of the lower insulation cover 301, with one end of each guide rod 47 fixedly connected to the end of the clamping plate 42 near the threaded rod 41. By setting the auxiliary structure 4 and adjusting the clamping plate 42, tanks 1 of different sizes can be fixed inside the lower insulation cover 301, thereby improving the applicability of the insulation and protection plate. A rubber pad 44 is fixedly connected to the side of the clamping plate 42 away from the threaded rods 41, and the size of the rubber pad 44 is adapted to one side of the clamping plate 42. The rubber pad 44 can increase the friction on one side of the clamping plate 42, thereby improving the limiting effect of the clamping plate 42 on the tank 1. Two limiting rings 45 are fixedly connected to the outer wall of the lower insulation cover 301. The inner wall of the limiting ring 45 fits against the arc surface of the threaded rod 41, and a pressure rod 46 is threaded through the outer wall of the limiting ring 45. One end of the pressure rod 46 abuts against the arc surface of the threaded rod 41. After the clamping plate 42 clamps the tank 1 securely, rotating the pressure rod 46 to abut against the arc surface of the threaded rod 41 can lock the threaded rod 41, thereby preventing the threaded rod 41 from shaking.

[0037] The working principle of the external heat insulation and protection plate for liquid tank provided by this utility model is as follows: When it is necessary to adjust the upper heat insulation cover 304 to provide heat insulation and protection for the outside of the liquid tank, first start the cylinder 317 to drive the connecting rod 318 to rotate. The connecting rod 318 drives the turntable 315 to rotate. The turntable 315 drives the rotating shaft 306 to rotate along the inner wall of the fixed seat 305. At the same time, the rotating shaft 306 drives the connecting plate 307. The connecting plate 307 drives the upper heat insulation cover 304 to rotate. When the upper heat insulation cover 304 rotates to the position directly above the lower heat insulation cover 301... After that, the operation of cylinder 317 can be stopped. Then, servo motor 311 is started to drive drive gear 312 to rotate. Drive gear 312 drives driven gear 310 to rotate. Driven gear 310 drives lead screw 308 to rotate. Lead screw 308 drives ear plate 309, causing ear plate 309 to move upper insulation cover 304 closer to lower insulation cover 301. When upper insulation cover 304 and lower insulation cover 301 are aligned, the operation of servo motor 311 can be stopped. At this time, the interiors of upper insulation cover 304 and lower insulation cover 301 form a... A sealed space is provided to insulate and protect the liquid tank. When the upper insulation cover 304 needs to be opened, the servo motor 311 is first started to drive the drive gear 312 to rotate in the opposite direction, causing the upper insulation cover 304 to move away from the lower insulation cover 301. Then, the cylinder 317 is started to drive the connecting rod 318 to rotate in the opposite direction, causing the upper insulation cover 304 to rotate in the opposite direction. When the connecting plate 307 drives the upper insulation cover 304 to rotate, the slide rod 320 fixed on the connecting plate 307 will slide along the inner wall of the arc-shaped hole 319. The angle of the hole 319 is limited, so the rotation angle of the upper insulation cover 304 can be limited. In addition, when the lead screw 308 drives the ear plate 309 and the upper insulation cover 304 to move, the positioning rod 314 fixed on one side of the ear plate 309 will move through the surface of the positioning plate 313, thereby preventing the ear plate 309 and the upper insulation cover 304 from rotating and shifting during the movement process. Finally, when the upper insulation cover 304 and the lower insulation cover 301 are docked, the sealing ring 303 can improve the sealing between the upper insulation cover 304 and the lower insulation cover 301.

[0038] When it is necessary to adjust the clamping plate 42 to clamp and limit the tank 1, first place the tank 1 inside the lower insulation cover 301, then rotate the rotating rod 43 to drive the threaded rod 41 to rotate. The threaded rod 41 drives the clamping plate 42, causing the clamping plate 42 to move closer to the tank 1 under the guidance and positioning of the guide rod 47. When the two clamping plates 42 drive the rubber pad 44 to abut and stabilize against the outer wall of the tank 1, the rotation of the rotating rod 43 can be stopped. Finally, rotate the pressure rod 46 to abut against the arc surface of the threaded rod 41, thus completing the clamping and limiting of the tank 1. In the limiting operation, when it is necessary to remove the tank 1 inside the lower insulation cover 301, first rotate the pressure rod 46 to separate it from the threaded rod 41, releasing the lock on the threaded rod 41. Then rotate the rotating rod 43 to drive the threaded rod 41 to rotate in the opposite direction, so that the threaded rod 41 drives the clamping plate 42. The clamping plate 42 drives the rubber pad 44 to separate from the tank 1. Then the tank 1 can be removed from the inside of the lower insulation cover 301. The rubber pad 44 can increase the friction on one side of the clamping plate 42, thereby improving the limiting effect of the clamping plate 42 on the tank 1.
