Description

Technical Field

[0001] This utility model relates to the field of chemical equipment, and in particular to a fouling-resistant graphite evaporator. Background Technology

[0002] A graphite evaporator is a heat exchange device that utilizes the excellent thermal conductivity and chemical stability of graphite materials to heat a liquid and evaporate it, thereby separating out pure solvents or other substances.

[0003] When using a graphite evaporator to evaporate a liquid, the liquid to be evaporated is usually fed into the graphite evaporator through a feed pipe. After the liquid enters the graphite evaporator, the evaporator heats the graphite. The thermal conductivity of the graphite causes the liquid to quickly absorb heat and rise in temperature. Once the liquid reaches the saturation temperature, evaporation begins.

[0004] Currently, some liquids that need to be evaporated contain impurities before entering the graphite evaporator. After evaporation, these impurities often remain inside the graphite evaporator, forming residual dirt and affecting its service life. To address this issue, a dirt-resistant graphite evaporator is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fouling-resistant graphite evaporator, which aims to improve the problem in the prior art where impurities in the evaporated liquid easily leave fouling residue inside the graphite evaporator after evaporation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fouling-resistant graphite evaporator, comprising a shell, an inlet pipe fixedly connected to the left end of the shell, an outlet pipe fixedly connected to the inner wall of the shell, an anti-fouling mechanism provided inside the inlet pipe, the anti-fouling mechanism comprising a mounting frame, the outer wall of the mounting frame slidably connected to the inner wall of the inlet pipe, a filter screen fixedly connected to the inner wall of the mounting frame, a rotating ring rotatably connected to the inner wall of the mounting frame, an mounting rod rotatably connected to the outer wall of the rotating ring, a cleaning brush fixedly connected to the outer wall of the mounting rod, a directional component provided outside the rotating ring and inside the mounting rod, a starting component provided outside the mounting rod, a control rod fixedly connected to the inner wall of the inlet pipe, a control groove provided on the outer wall of the control rod, a control ball fixedly connected to the inner wall of the rotating ring, a reset component provided inside the inlet pipe, and a collection box threadedly connected to the bottom of the inlet pipe.

The inner wall of the rotating ring has a moving groove, and a stop block is slidably connected to the inner wall of the moving groove. The outer wall of the stop block is elastically connected to the inner wall of the moving groove by a spring.

[0009] As a further description of the above technical solution:

[0010] The starting assembly includes a connecting rod, the outer wall of which is fixedly connected to the outer wall of the mounting rod near the left side, and a control ball is fixedly connected to the end of the connecting rod away from the mounting rod.

[0011] As a further description of the above technical solution:

[0012] The reset assembly includes a positioning ring, the outer wall of which is fixedly connected to the inner wall of the liquid inlet pipe, and the left end of the positioning ring is elastically connected to the right end of the mounting frame via an elastic telescopic rod.

[0013] As a further description of the above technical solution:

[0014] The mounting frame is circular in shape, and the cross-section of the mounting frame is formed by connecting a right-angled triangle on the left and a rectangle on the right.

[0015] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting up an installation frame, filter screen, rotating ring, installation rod, cleaning brush, control rod, control groove, control ball, etc., it is ensured that the impurities carried in the liquid to be evaporated can be filtered by the filter screen. When the filter screen is clogged, it can be pushed by the thrust when the liquid enters the equipment. During the movement, the surface of the filter screen is cleaned by the cleaning brush, thereby achieving the effect of cleaning the impurities carried in the liquid to be evaporated and ensuring that the graphite evaporator is not prone to leaving dirt.

[0023] 2. In this utility model, the arrangement of the collection box, ratchet, moving groove, stop block, connecting rod, and control ball ensures that when the flow rate of the liquid to be evaporated is too fast, the control ball can be pushed by the thrust of the liquid flow, thereby causing the mounting rod to rotate and driving the cleaning brush to rotate. This ensures that when a large amount of liquid flows in, the cleaning brush can always maintain a cleaning state, thus preventing the liquid intake effect from being affected by the long time required to push the filter screen when the liquid flow rate is fast.

A connecting rod passing through the center point of the mounting frame 41 is provided inside the right side of the mounting frame 41. The outer wall of the mounting frame 41 is slidably connected to the inner wall of the inlet pipe 2. A filter screen 42 is fixedly connected to the inner wall of the mounting frame 41. Through the setting of the filter screen 42, impurities carried inside the evaporated liquid can be filtered out by the filter screen 42. The filter achieves the effect of preventing fouling in the graphite evaporator. A rotating ring 43 is rotatably connected to the inner wall of the mounting frame 41. The rotating ring 43 is circular in shape. A mounting rod 44 is rotatably connected to the outer wall of the rotating ring 43. The rear end of the mounting rod 44 is hollow.

The bristles of the cleaning brush 45 are located on the side close to the filter screen 42, and the cleaning brush 45 can contact the surface of the filter screen 42.

[0035] Reference Figure 4 - Figure 6 A limiting assembly 46 is provided on the outside of the rotating ring 43 and inside the mounting rod 44. The limiting assembly 46 includes a ratchet 461. The outside of the ratchet 461 is set as a smooth surface. The ratchet groove of the ratchet 461 is set on the inside. The outer wall of the ratchet 461 is fixedly connected to the inner wall of the mounting rod 44. A moving groove 462 is opened on the inner wall of the rotating ring 43. A stop block 463 is slidably connected to the inner wall of the moving groove 462. The shape of the stop block 463 matches the shape of a single ratchet groove of the ratchet 461. The outer wall of the stop block 463 and the inner wall of the moving groove 462 are elastically connected by a spring 464. One end of the spring 464 is fixedly connected to the outer wall of the stop block 463, and the other end of the spring 464 is fixedly connected to the inner wall of the moving groove 462.

[0036] Reference Figure 2 - Figure 4An activation component 47 is provided on the outside of the mounting rod 44. The activation component 47 includes a connecting rod 471. The connecting rod 471 is elongated and there are multiple connecting rods 471 arranged in a circular array with the circle corresponding to the outer wall of the mounting rod 44. The outer wall of the connecting rod 471 is fixedly connected to the outer wall of the mounting rod 44 near the left side. A directional ball 472 is fixedly connected to the end of the connecting rod 471 away from the mounting rod 44. The directional ball 472 is a concave hemisphere and the concave area of ​​the directional ball 472 is inclined at a 45-degree angle. By setting the inclination, it is ensured that the inner side of the directional ball 472 is subjected to water pressure and can rotate under the action of the inclination angle. A control rod 48 is fixedly connected to the inner wall of the liquid inlet pipe 2. The outer diameter of the control rod 48 matches the inner diameter of the rotating ring 43.

[0037] Reference Figure 2 , Figure 5 and Figure 6 The outer wall of the control rod 48 is provided with a control groove 49, which is spiral in shape. The inner wall of the rotating ring 43 is fixedly connected with a control ball 410. The control ball 410 is located inside the control groove 49, and the diameter of the control ball 410 matches the width of the control groove 49.

[0038] Reference Figure 2 and Figure 3 The inlet pipe 2 is equipped with a reset assembly 411, which includes a positioning ring 4111. The outer wall of the positioning ring 4111 is fixedly connected to the inner wall of the inlet pipe 2. The positioning ring 4111 is annular in shape, and the positioning ring 4111 and the annular area of ​​the mounting frame 41 are at the same horizontal position. The left end of the positioning ring 4111 is elastically connected to the right end of the mounting frame 41 through an elastic telescopic rod 4112. One end of the elastic telescopic rod 4112 is fixedly connected to the left end of the positioning ring 4111, and the other end of the elastic telescopic rod 4112 is fixedly connected to the right end of the mounting frame 4111. The end is fixedly connected to the right end of the mounting frame 41. The elastic telescopic rod 4112 is composed of an outer ordinary telescopic rod and an inner elastic element. The telescopic rod ensures that the elastic element is not easily damaged due to contact with the liquid to be evaporated or collision with impurities. The bottom of the liquid inlet pipe 2 is threadedly connected to the collection box 412. The inner side of the collection box 412 is provided with a rubber gasket. The gasket ensures that after the collection box 412 is installed, the liquid is not easily leaked out through the gap between the collection box 412 and the liquid inlet pipe 2.

[0039] Working principle: When the liquid to be evaporated is introduced into the liquid inlet pipe 2, if the liquid flow rate is fast, there will be a large thrust during the liquid entry process. Under the action of the thrust, the liquid enters the interior of the directional ball 472 and can push the inclined surface of the directional ball 472 through the thrust, thereby causing the directional ball 472 to rotate.

[0040] When the control ball 472 rotates, the control ball 472 drives the mounting rod 44 to rotate through the connecting rod 471, thereby causing the mounting rod 44 to drive the cleaning brush 45 to rotate, so that the cleaning brush 45 cleans the impurities attached to the surface of the filter screen 42 during the rotation.

[0041] If the liquid flow rate is slow, the thrust cannot push the control ball 472. However, because the flow rate is slow at this time, the amount of impurities filtered by the filter screen 42 is small at the same time. Since the impurities have their own gravity, some impurities can fall off on their own when the cleaning brush 45 does not clean them. Therefore, although the cleaning brush 45 is not used to clean the filter screen 42 at this time, the impact is not significant. Moreover, because the cleaning brush 45 is not used frequently, its service life is increased.

[0042] If the filter screen 42 becomes clogged, the liquid pushes the filter screen 42, causing it to move from left to right under the force of the push. When the filter screen 42 moves, it drives the rotating ring 43 to move from left to right. Since the control ball 410 is inside the rotating ring 43, when the rotating ring 43 moves, it drives the control ball 410 to move from left to right. During the movement, the control ball 410 slowly rotates along the control groove 49, thereby causing the rotating ring 43 to rotate.

[0043] When the rotating ring 43 rotates, it drives the abutment block 463 to rotate, and the abutment block 463 is in direct contact with the ratchet 461 at this time. Therefore, the abutment block 463 pushes the straight surface of the ratchet 461, causing the mounting rod 44 to rotate together with it, thereby causing the cleaning brush 45 to rotate and clean the filter screen 42.

[0044] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
