Technical Field

[0001] This utility model relates to the field of filtration and slag removal equipment technology, and more specifically, it relates to a pre-filtration and slag removal device for an MVR evaporator. Background Technology

[0002] MVR technology is a relatively advanced energy-saving technology that can achieve efficient recovery and reuse of low-grade waste heat during the evaporation process, thereby reducing the demand for external energy. MVR technology has received increasing attention due to its low energy consumption, compact structure, and high thermal energy utilization rate. However, the existing MVR evaporator pre-filter slag removal device is inconvenient for collecting filter slag. Utility Model Content

[0003] (1) Technical problems to be solved

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a pre-filter slag removal device for MVR evaporators, which has the feature of facilitating the collection of filter slag.

[0005] (2) Technical solution

[0006] To achieve the above objectives, this utility model provides a pre-filter slag removal device for an MVR evaporator, comprising a slag removal box and a movable plate. A first filter screen and a fixed shell are fixedly connected to opposite inner walls of the slag removal box. The end face of the first filter screen is fixed to the surface of the fixed shell. A rectangular opening is provided at the bottom of the fixed shell. A collecting shell is movably connected inside the fixed shell. A second filter screen is provided at the bottom of the collecting shell. An opening is provided on the surface of the slag removal box. A mounting base is fixedly connected to the surface of the collecting shell. The mounting base is movably connected inside the opening. Slots are provided on opposite inner walls of the opening. Grooves are provided on both sides of the mounting base. A telescopic component is fixedly connected to the inner wall of the groove. A movable block is fixedly connected to one end of the telescopic component. The bottom of the movable block is fixedly connected to a trapezoidal locking block, one end of which is engaged in the inside of a slot. A connecting block is fixedly connected to the side of the movable block. A rectangular through hole is provided on the surface of the mounting base. A pull plate is fixedly connected to the connecting block through the rectangular through hole. Bearings are provided on the opposite inner walls of the slag removal box. A rotating shaft is provided inside each of the two bearings. The opposite ends of the two rotating shafts are fixedly connected to the same threaded column. A fixing frame is fixedly connected to the surface of the slag removal box, and a motor is fixedly connected to the fixing frame. The output end of the motor is fixedly connected to one end of the rotating shaft. A threaded hole is provided on the surface of the moving plate. The threaded column is threaded into the inside of the threaded hole. A cleaning brush is provided at the bottom of the moving plate. The bottom of the cleaning brush overlaps with the top of the first filter screen.

[0007] When using the MVR evaporator pre-filter slag removal device of this technical solution, wastewater is filtered through the first filter screen. The motor drives the threaded column to rotate, causing the threaded column to rotate inside the threaded hole. This causes the moving plate to move on the surface of the threaded column, which in turn causes the cleaning brush to move on the surface of the first filter screen. The cleaning brush collects the filter slag into the collection shell, facilitating the collection of the filter slag. Furthermore, by pulling the pull plate, under the elastic force of the telescopic component, the pull plate moves through the connecting block to drive the movable block, causing the movable block to disengage the trapezoidal locking block from the slot. Simultaneously, the pull plate is pulled outward, causing the pull plate to drive the collection shell to detach from the slag removal box through the mounting base, facilitating the processing of the collected filter slag.

[0008] Furthermore, the telescopic assembly includes a telescopic rod, on the surface of which a spring is movably sleeved. One end of the telescopic rod and the spring is fixedly connected to the inner wall of the groove, and the other end of the telescopic rod and the spring is fixedly connected to the movable block.

[0009] Furthermore, the surface of the pull plate is provided with a rubber pad.

[0010] Furthermore, the same limiting rod is fixedly connected to the inner walls of the slag removal box, and a limiting hole is opened on the surface of the moving plate, with the limiting rod slidably connected inside the limiting hole.

[0011] Furthermore, a guide plate is fixedly connected to the inner wall of the slag removal box, a water inlet pipe is fixedly connected to the top of the slag removal box, a drain pipe is fixedly connected to the surface of the slag removal box, a valve is installed on the drain pipe, and an operation panel is installed on the surface of the slag removal box.

[0012] (3) Beneficial effects

[0013] In summary, this utility model has the following beneficial effects:

[0014] 1. The MVR evaporator pre-filter and slag removal device filters wastewater through a first filter screen and a collection shell. The motor drives the threaded column to rotate, causing the threaded column to rotate inside the threaded hole. This causes the moving plate to move on the surface of the threaded column, which in turn drives the cleaning brush to move on the surface of the first filter screen. The cleaning brush collects the filter residue into the collection shell, facilitating the collection of the filter residue.

[0015] 2. The pre-filter slag removal device for this MVR evaporator is equipped with a pull plate, a telescopic component, a trapezoidal locking block, and a locking groove. By pulling the pull plate, under the elastic force of the telescopic component, the pull plate moves the movable block through the connecting block, causing the movable block to disengage the trapezoidal locking block from the locking groove. At the same time, the pull plate is pulled outward, causing the pull plate to move the collection shell away from the slag removal box through the mounting base, which facilitates the processing of the collected filter slag.

[0024] Example:

[0025] The following is in conjunction with the appendix Figure 1-4 The present invention will be described in further detail below.

[0026] Please see Figure 1-4This utility model provides a technical solution: a pre-filter slag removal device for an MVR evaporator, including a slag removal box 1 and a movable plate 19. A first filter screen 2 and a fixed shell 3 are fixedly connected to the inner walls of the slag removal box 1. The end face of the first filter screen 2 is fixed to the surface of the fixed shell 3. A rectangular opening is provided at the bottom of the fixed shell 3. A collecting shell 4 is movably connected inside the fixed shell 3. A second filter screen 5 is provided at the bottom of the collecting shell 4. An opening 6 is provided on the surface of the slag removal box 1. A mounting base 7 is fixedly connected to the surface of the collecting shell 4 and movably connected inside the opening 6. Openings are provided on the inner walls of the opening 6. The mounting base 7 has grooves 9 on both sides of the slot 8 and the mounting base 7. A telescopic component 10 is fixedly connected to the inner wall of the groove 9. A movable block 11 is fixedly connected to one end of the telescopic component 10. A trapezoidal locking block 12 is fixedly connected to the bottom of the movable block 11. One end of the trapezoidal locking block 12 is engaged inside the slot 8. A connecting block 14 is fixedly connected to the side of the movable block 11. A rectangular through hole 13 is provided on the surface of the mounting base 7. A pull plate 15 is fixedly connected to the connecting block 14 through the rectangular through hole 13. Bearings are provided on the opposite inner walls of the slag removal box 1. A rotating shaft passes through the interior of each bearing. A common connecting plate is fixedly connected to the opposite ends of the two rotating shafts. A threaded column 17 is fixedly connected to a fixed frame on the surface of the slag removal box 1, and a motor 18 is fixedly connected to the fixed frame. The output end of the motor 18 is fixedly connected to one end of the rotating shaft. A threaded hole 20 is opened on the surface of the moving plate 19, and the threaded column 17 is threadedly connected inside the threaded hole 20. A cleaning brush 23 is provided at the bottom of the moving plate 19, and the bottom of the cleaning brush 23 overlaps with the top of the first filter screen 2. By setting the first filter screen 2 and the collection shell 4, the sewage is filtered through the first filter screen 2. The motor 18 drives the threaded column 17 to rotate, so that the threaded column 17 rotates inside the threaded hole 20, and the moving plate 19 rotates within the threaded hole 20. The surface movement of the textured column 17 causes the moving plate 19 to drive the cleaning brush 23 to move on the surface of the first filter screen 2. The cleaning brush 23 collects the filter residue into the collection shell 4, which facilitates the collection of the filter residue. By setting up a pull plate 15, a telescopic component 10, a trapezoidal locking block 12 and a locking groove 8, by pulling the pull plate 15, under the elastic force of the telescopic component 10, the pull plate 15 drives the movable block 11 to move through the connecting block 14. The movable block 11 drives the trapezoidal locking block 12 to disengage from the locking groove 8. At the same time, the pull plate 15 is pulled outward, so that the pull plate 15 drives the collection shell 4 to disengage from the slag removal box 1 through the mounting base 7, which facilitates the processing of the collected filter residue.

[0027] Specifically, the telescopic assembly 10 includes a telescopic rod 101, a spring 102 is movably sleeved on the surface of the telescopic rod 101, one end of the telescopic rod 101 and the spring 102 is fixedly connected to the inner wall of the groove 9, and the other end of the telescopic rod 101 and the spring 102 is fixedly connected to the movable block 11.

[0028] By adopting the above technical solution, the telescopic component 10 plays a role in telescopic elasticity.

[0029] Specifically, the surface of the pull plate 15 is provided with a rubber pad 16.

[0030] By adopting the above technical solution, the friction between the palm and hand is increased by the rubber pad 16, which facilitates the movement of the pull plate 15.

[0031] Specifically, the same limiting rod 21 is fixedly connected to the inner wall of the slag removal box 1, and a limiting hole 22 is opened on the surface of the moving plate 19. The limiting rod 21 is slidably connected inside the limiting hole 22.

[0032] By adopting the above technical solution, the limiting rod 21 slides inside the limiting hole 22, which plays a limiting role on the moving plate 19.

[0033] Specifically, a guide plate 24 is fixedly connected to the inner wall of the slag removal box 1, a water inlet pipe 27 is fixedly connected to the top of the slag removal box 1, a drain pipe 25 is fixedly connected to the surface of the slag removal box 1, a valve 26 is installed on the drain pipe 25, and an operation panel is installed on the surface of the slag removal box 1.

[0034] By adopting the above technical solution, the guide plate 24 plays a guiding role.

[0035] It should be noted that a backwash nozzle (not shown) can be added to the bottom of the slag removal box to periodically backwash the first filter screen, thereby improving working efficiency and service life.

[0036] The working principle of this utility model is as follows:

[0037] In use, the wastewater is first fed into the sludge removal box 1 through the inlet pipe 27 and filtered through the first filter screen 2. The motor 18 is started through the operation panel, which drives the threaded column 17 to rotate. The threaded column 17 rotates inside the threaded hole 20, causing the moving plate 19 to move on the surface of the threaded column 17. The moving plate 19 drives the cleaning brush 23 to move on the surface of the first filter screen 2. The cleaning brush 23 collects the filter residue into the collection shell 4. The filter residue is collected and filtered again through the second filter screen 5. When it is necessary to clean the filter residue in the collection shell 4, the pull plate 15 is pulled. Under the elastic force of the telescopic component 10, the pull plate 15 moves the movable block 11 through the connecting block 14. The movable block 11 drives the trapezoidal locking block 12 to disengage from the slot 8. At the same time, the pull plate 15 is pulled outward, causing the pull plate 15 to drive the collection shell 4 to disengage from the sludge removal box 1 through the mounting base 7. The collected filter residue can then be processed.

[0038] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
