Description

Technical Field

[0001] This utility model relates to the technical field of evaporator accessories, specifically a film distributor for a high-efficiency evaporator used in wastewater treatment. Background Technology

[0002] In the field of industrial wastewater treatment, evaporators are commonly used high-concentration wastewater treatment equipment. They use heating to evaporate water, thereby concentrating or crystallizing the solute. The performance of the membrane distributor directly affects evaporation efficiency and energy consumption. Traditional membrane distributors often employ simple spray, overflow, or rotary structures.

[0003] Chinese utility model patent CN214597273U discloses a membrane distribution device for a high-efficiency wastewater evaporator, which has the following drawbacks:

[0004] 1. The design of the pre-distribution pipe and the horizontal pipe relies on the natural accumulation of wastewater in the pre-distribution tank, which may lead to uneven distribution, especially at low flow rates. Moreover, the accumulation of wastewater in the pre-distribution tank can easily form residual dirt, which will also have a certain impact on the flow of wastewater.

[0005] 2. The membrane tube adopts an integrated structure. However, when the internal distribution plate has a problem and needs to be replaced, the extra parts need to be removed before the distribution plate can be replaced, which is more troublesome.

[0006] Therefore, we propose a membrane distributor for high-efficiency evaporators used in wastewater treatment to address the aforementioned problems. Utility Model Content

[0007] The purpose of this invention is to provide a membrane distributor for a high-efficiency evaporator used in wastewater treatment, in order to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A membrane distribution device for a high-efficiency evaporator used in wastewater treatment includes a membrane distribution component, a tube sheet, and a flow distribution assembly. The top of the membrane distribution component is provided with a water inlet cover, and a water inlet pipe is provided on the water inlet cover. A uniform distribution assembly is provided between the inner walls of the membrane distribution component.

[0010] The tube sheet is disposed between the bottom inner walls of the film-forming component, and multiple film-forming components are also disposed between the tube sheet and the bottom of the film-forming component.

[0011] The diversion component is disposed inside the film-forming component and is located above the uniform distribution component. The diversion component includes a diversion plate, a rotating seat, and an adjustment component. The diversion plate is fixed between the inner walls of the film-forming component and has a circular groove. The rotating seat is eccentrically rotatably disposed in the groove. The adjustment component is disposed on each side wall of the rotating seat. The other end of the adjustment component can be movably adjusted and can slide in contact with the inner surface of the groove.

[0012] Multiple filter covers are installed on the bottom wall of the diversion plate, and the bottom end of the water inlet pipe is located above the center of the diversion plate.

[0013] According to the above technical solution, a diffusion component is also installed between the inner walls of the water inlet pipe near the bottom end. The diffusion component includes a guide plate and a spiral tube. Several side holes are opened on the outer surface of the spiral tube along its circumference. The side holes are located near the bottom end of the spiral tube. The bottom end of the spiral tube is fixed on the guide plate and its top end is threadedly connected between the inner walls of the water inlet pipe. The longitudinal section of the guide plate is an isosceles trapezoid.

[0014] According to the above technical solution, the adjustment assembly includes a connecting plate and an adjustment plate. One end of the connecting plate is connected to the side wall of the rotating seat. An adjustment block is elastically slidably arranged on the top of the connecting plate along its length direction. One end of the adjustment plate is rotatably connected to the adjustment block via a shaft, and the other end of the adjustment plate is provided with a pointed structure.

[0015] According to the above technical solution, the membrane component includes a tube body one, a tube body three, and multiple tube bodies two. The multiple tube bodies two are arranged vertically connected between tube body one and tube body three. A positioning pin one is elastically provided on tube body one, and a positioning pin two that can be slidably adjusted is provided through tube body two. The top end of the positioning pin one can be inserted into the tube body two adjacent to tube body one, and the top end of the positioning pin two located in the tube body two directly above can be inserted into tube body three.

[0016] According to the above technical solution, the bottom wall of the second tube is connected to a rotating shaft 1 that rotates and adjusts synchronously with it, and the top wall of the uppermost second tube is also provided with a rotating shaft 2 that rotates synchronously with it. The rotating shaft 2 rotates between the inner walls of the third tube, and the rotating shaft 1 rotates between the inner walls of the first tube or the second tube.

[0017] According to the above technical solution, the uniform distribution component includes multiple uniform distribution plates, each uniform distribution plate is fixed between the inner walls of one of the tube bodies two, and the diverter plate is fixed between the inner walls of the tube body three. Each uniform distribution plate is provided with several uniform distribution holes, and the top of the film forming component is fixed on the uniform distribution plate located at the bottom.

[0018] Compared with the prior art, the beneficial effects achieved by this utility model are:

[0019] (1) By disassembling the overall film distribution device into an assembly structure of tube body one, tube body two and tube body three, and setting rotating shaft one, rotating shaft two, and positioning pin one and positioning pin two at the connection, the uniform distribution plate can be easily and quickly replaced and cleaned by rotating adjustment. At the same time, the positioning pin one and positioning pin two can improve the speed of connection and assembly by limiting their vertical direction.

[0020] (2) By setting up a rotating seat, a connecting plate and an adjusting plate in the diversion plate, the elastic movement of the adjusting block on the connecting plate is used to control the synchronous adjustment process of the adjusting plate, so that the rotating seat can continuously adjust the state of the connecting plate and the adjusting plate during the eccentric movement, which effectively improves the fluidity of wastewater transportation.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-4The present invention provides a technical solution: a membrane distribution device for a high-efficiency evaporator used in wastewater treatment, comprising a membrane distribution component 1, a tube sheet 5, and a water inlet cover 2. The membrane distribution component 1 includes a first tube 11, a second tube 12, and a third tube 13, wherein one first tube 11 and one third tube 13 are respectively provided, and the first tube 11 is located directly above the third tube 13. Multiple second tubes 12 are provided and are installed vertically between the top wall of the first tube 11 and the bottom wall of the third tube 13. The first tube 11 is installed on the outer surface of the tube sheet 5. The water inlet cover 2 is installed on the top of the third tube 13 by means of a threaded connection, and a water inlet pipe 21 is connected in the middle of the water inlet cover 2.

[0028] Among them, a diffusion assembly is installed between the inner walls of the water inlet pipe 21 near the bottom. The diffusion assembly includes a guide plate 7 and a spiral tube 71. The longitudinal section of the guide plate 7 is an isosceles trapezoid. The bottom end of the spiral tube 71 is connected and fixed to the top surface of the guide plate 7. Several side holes are opened on the outer surface of the spiral tube 71 near the guide plate 7. An external thread is opened on the outer surface of the spiral tube 71 near its top. The external thread of the spiral tube 71 is installed between the inner walls of the water inlet pipe 21 by means of a threaded connection.

[0029] A uniform distribution component and a flow distribution component are provided between the inner walls of the membrane component 1, with the uniform distribution component located below the flow distribution component.

[0030] It should be further explained that the wastewater flows downward from the inlet pipe 21, and after passing through the diffusion component, the wastewater is diffused. Then, the wastewater is first diverted by the diversion component and then passes through the uniform distribution component, and finally flows through the tube sheet 5.

[0031] The uniform distribution assembly includes at least two uniform distribution plates 4, all of which are of equal size and have a plurality of uniform distribution holes. The diameter of the uniform distribution holes on the upper uniform distribution plate 4 is larger than that on the lower uniform distribution plate 4, and sealing rings are provided at the top and bottom edges of the uniform distribution plates 4.

[0032] The number of tube bodies 12 is equal to the number of evenly distributed plates 4. The sealing ring is fixed to the inner surface of the tube body 12 in a detachable manner. A vertical hole is opened between the inner walls of the tube body 12. A positioning pin 121 is slidably installed in the vertical hole. A vertical groove communicating with the vertical hole is also opened on one side of the vertical hole on the tube body 12. A lever is slidably installed in the vertical groove. One end of the lever is fixed to the adjacent positioning pin 121. The lever drives the positioning pin 121 to move up and down. When the lever moves to contact the top or bottom surface of the vertical groove, its position can be fixed by magnetic attraction. That is, a magnet (not shown in the figure) is embedded on the surface or side wall of the lever opposite to the vertical groove.

[0033] Among them, a cylindrical top groove is provided on the top surface of the tube body 11. A positioning pin 111 is elastically provided in the top groove. One end of the positioning pin 111 can be inserted into the vertical hole of the tube body 2 12 which is adjacent to the tube body 11. When the top of the positioning pin 111 is located in the vertical hole of the tube body 2 12, the top end of the positioning pin 111 contacts the bottom end of the positioning pin 2 121, and at this time the lever block contacts and is fixed together with the top surface of the vertical groove.

[0034] In addition, a rotating shaft with a "T" structure is fixedly connected to the lower surface of the second tube 12. The rotating shaft is rotatably disposed between the inner wall of the second tube 12 or the first tube 11 that it contacts. A rotating shaft with a "T" structure is also fixedly connected to the upper surface of the uppermost second tube 12. The rotating shaft is rotatably disposed between the inner wall of the third tube 13 that it contacts.

[0035] Sealing strips are embedded on the contact surfaces of tube 11 and the bottommost tube 212, the contact surfaces of adjacent tube 212, and the contact surfaces of the topmost tube 212 and tube 313.

[0036] It should be further explained that the arrangement of rotating shaft one and rotating shaft two allows multiple uniform distribution plates 4 to be rotated and adjusted independently, thus eliminating the need for additional disassembly work to replace the uniform distribution plates 4. When it is necessary to replace the uniform distribution plate 4, the corresponding lever block and the lever block below it are moved downwards, causing the positioning pin two 121 to move downwards and press down on the positioning pin one 111. When the lever block slides to the bottom surface of the vertical groove, the positioning pin two 121 is completely located in the corresponding vertical hole, and the positioning pin one 111 is also completely pressed into the top. Inside the groove (i.e., the top surface of positioning pin 111 is at the same level as the top surface of the groove), manually rotate the tube 2 12 corresponding to the uniform distribution plate 4 to be replaced to one side, clean and replace the uniform distribution plate 4 on the tube 2 12, and then rotate it back to its original position. Then, push the lever upward so that positioning pin 2 121 is reset upward and its top end is inserted into the tube 2 12 or tube 3 13 above. As positioning pin 2 121 moves upward, positioning pin 111 also bounces upward and resets under the action of the bottom spring and is inserted into the tube 2 12 above.

[0037] The film-forming assembly 6 includes a connecting column 61, a film-forming block 62, and a connecting rod 63. The top of the connecting column 61 is fixed to the bottom surface of the lowest uniformly distributed plate 4. Several connecting holes are opened on the tube sheet 5. The connecting holes are integrated with the upper opening of the heat exchange tube. The film-forming block 62 is arranged in a frustum shape and is located in the connecting hole. The bottom of the film-forming block 62 is smaller than the diameter of the upper opening of the heat exchange tube. The connecting rod 63 is connected between the connecting column 61 and the film-forming block 62, and the connecting rod 63 is a screw.

[0038] It should be further explained that by adjusting the length of the screw exposed outside the connecting post 61, the height of the film-forming block 62 in the connecting hole can be adjusted and changed, thereby controlling the gap between the bottom circumferential edge of the film-forming block 62 and the inner wall of the upper opening of the heat exchange tube. Ultimately, the wastewater adheres to the inner wall of the heat exchange tube and flows downward in a film-like manner, and evaporates in the heat exchange tube.

[0039] The diversion assembly includes a diversion plate 3, a rotating seat 32, and an adjustment assembly. The diversion plate 3 has a circular groove and is fixed between the inner surfaces of the tube body 13 by means of a shaft connection. A guide plate 131 with an annular structure is also fixedly connected between the top of the diversion plate 3 and the inner surface of the tube body 13.

[0040] The rotating seat 32 is eccentrically mounted in the groove. The rotating seat 32 is driven by a motor (the motor is installed between the bottom inner walls of the diverter plate 3, not shown in the figure). The rotating seat 32 has a regular polygonal cross-section. An adjustment assembly is provided between the side wall of the rotating seat 32 and the inner surface of the groove. The adjustment assembly includes a connecting plate 33 and an adjusting plate 35. One end of the connecting plate 33 is fixedly connected to the side wall of the rotating seat 32. A transverse groove is formed along the length of one side wall of the connecting plate 33. A slider is slidably mounted in the transverse groove, and a guide shaft is fixed along the length of the transverse groove, passing through and slidingly contacting the slider. Furthermore, an adjusting spring is sleeved on the guide shaft. One end of the adjusting spring is connected to the end wall of the transverse groove near the rotating seat 32, and the other end is connected to the side wall of the slider. An "L"-shaped adjusting block 34 is also slidably arranged on the connecting plate 33. The adjusting block 34 is fixed to the slider as a whole. The adjusting plate 35 is slidably arranged on the other side wall of the connecting plate 33 along with the adjusting block 34. The adjusting plate 35 and the adjusting block 34 are rotatably connected by a shaft. The end of the adjusting plate 35 that contacts the groove has a pointed structure. Multiple filter covers 31 are also fixedly installed on the bottom wall of the diverter plate 3. The filter covers 31 can be disassembled by means of threaded connection.

[0041] It should be further explained that the rotating seat 32 is driven by a motor (a rotary motor in this embodiment) to rotate eccentrically, thereby constantly controlling the length change of the adjusting component. When the distance between the rotating seat 32 and the inner surface of the groove decreases, the adjusting plate 35 is pressed towards the connecting plate 33 under the constraint of the inner surface of the groove, and a suitable amount of deflection occurs. This, in conjunction with the rotating seat 32, drives the adjusting component through the area with the small distance. Conversely, when the distance between the rotating seat 32 and the inner surface of the groove increases, the adjusting plate 35 will move synchronously away from the connecting plate 33 under the action of the adjusting spring, until the tip of the adjusting plate 35 contacts the inner surface of the groove. The wastewater flows down from the guide plate 7, continuously rotating and flowing synchronously in the area between multiple adjusting components, and finally flows down from the filter cover 31.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
