Description

Technical Field

[0001] This utility model relates to the field of evaporation and concentration equipment technology, and in particular to an MVR evaporator with inlet water filtration function. Background Technology

[0002] MVR (Mechanical Vapor Recompression) evaporators are widely used in chemical, pharmaceutical, food, and environmental protection industries as highly efficient and energy-saving evaporation equipment. They are used to treat high-salt wastewater and concentrate solutions. The core principle is to compress and heat the secondary steam generated by evaporation using a compressor, and then recycle the heated steam as a heat source.

[0003] However, the influent water often contains suspended impurities and organic impurities. Existing MVR evaporators generally lack efficient influent water pretreatment functions or are only equipped with simple filter screens. Single-layer metal filter screens can only remove large suspended impurities and cannot remove fine colloidal particles, hard ions, and organic matter. After fine impurities enter the evaporator with the influent water, they will still deposit and form scale in the heating tubes, reducing the service life of the evaporator. To address the above problems, an MVR evaporator with influent water filtration function is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an MVR evaporator with inlet water filtration function to solve the problems mentioned in the background art.

[0005] To solve the above problems, the following technical solution is provided: an MVR evaporator with water inlet filtration function, comprising an MVR evaporator body, a support plate fixedly installed on the upper outer wall of the MVR evaporator body, a filter box fixedly installed above the support plate and the outer wall of the filter box having a sealing structure, a water inlet pipe provided on one side of the sealing structure, fixed slide rails fixedly installed on both sides of the inner wall of the filter box, three sets of fixed slide rails arranged sequentially from top to bottom with a coarse filter plate, a fine filter plate and an activated carbon adsorption plate, the activated carbon adsorption plate being fixedly installed inside the mounting frame, a cleaning cabinet door being rotatably installed on the outer wall of the filter box, and a water inlet pipe fixedly installed at the bottom of the filter box, one end of the water inlet pipe penetrating the interior of the MVR evaporator body.

[0006] As a preferred embodiment of the above technical solution, the coarse filter plate, fine filter plate and activated carbon adsorption plate are adapted to the internal dimensions of the filter box, and limit blocks are fixedly installed on both sides of the outer wall of the coarse filter plate, fine filter plate and activated carbon adsorption plate, and the limit blocks are respectively slidably connected inside the fixed slide rail.

[0007] As a preferred embodiment of the above technical solution, the fine filter plate has a smaller pore size than the coarse filter plate, and handles are fixedly installed on the outer walls of the coarse filter plate, the fine filter plate, and the mounting frame.

[0008] As a preferred embodiment of the above technical solution, the sealing structure includes a connecting conduit fixedly installed on the outer wall of the filter box, a limiting plate fixedly installed at one end of the connecting conduit, a sealing groove being provided inside the limiting plate, and a sealing gasket and a sealing ring being respectively provided inside the sealing groove.

[0009] As a preferred embodiment of the above technical solution, a sealing convex ring is fixedly installed at one end of the water inlet pipe and the size of the sealing convex ring is adapted to the sealing groove. Both the water inlet pipe and the limiting plate are provided with multiple installation grooves of the same size.

[0010] As a preferred embodiment of the above technical solution, a limiting frame is fixedly installed on the outer wall of the connecting conduit at a position relative to the mounting groove. A positioning rod is fixedly installed inside the limiting frame. A rotating cylinder is rotatably installed on the outer wall of the positioning rod. A locking screw is fixedly installed on the outer wall of the rotating cylinder. A limiting cap is threadedly connected to the outer wall of one end of the locking screw.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This utility model device is equipped with a coarse filter plate, a fine filter plate, and an activated carbon adsorption plate. The coarse filter plate filters out larger impurities and pollutants in the water, the fine filter plate intercepts fine colloids in the water, and the activated carbon adsorption plate on the mounting frame filters and adsorbs ions and organic impurities. Finally, the water is transported to the MVR evaporator through the inlet pipe, which is conducive to the thorough filtration of the water source and improves the service life of the MVR evaporator. At the same time, the filter plate and the mounting frame can be slid out on the fixed slide rail by pulling the handle and using the limiting block for cleaning or replacement. The operation is simple.

[0012] 2. The device of this utility model is equipped with a sealing structure. The sealing convex ring on the water inlet pipe squeezes the sealing groove in the limiting plate, which causes the sealing ring and sealing gasket to be squeezed and sealed. When the water inlet pipe and the limiting plate are squeezed and relatively close, the outer cylinder of the positioning rod in the three limiting frames is rotated, which causes the cylinder to drive the locking screw to engage with the mounting groove on the outer wall of the limiting plate and the water inlet pipe. The locking screw is then rotated so that one end of the limiting cap on the outer wall is squeezed onto the water inlet pipe, thereby quickly splicing and fixing the water inlet pipe and the connecting conduit while improving the sealing performance.

It should be understood that the embodiments of the present invention are not limited in scope.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] like Figures 1 to 4 As shown, this embodiment provides an MVR evaporator with water inlet filtration function, including an MVR evaporator body 1. A support plate 2 is fixedly installed on the upper outer wall of the MVR evaporator body 1. A filter box 3 is fixedly installed above the support plate 2, and a sealing structure 5 is provided on the outer wall of the filter box 3. A water inlet pipe 4 is provided on one side of the sealing structure 5. Fixed slide rails 8 are fixedly installed on both sides of the inner wall of the filter box 3. The three sets of fixed slide rails 8 are arranged from top to bottom as a coarse filter plate 9, a fine filter plate 14, and an activated carbon adsorption plate 13. The activated carbon adsorption plate 13 is fixedly installed inside the mounting frame 10. A cleaning cabinet door 6 is rotatably installed on the outer wall of the filter box 3. A water inlet pipe 7 is fixedly installed at the bottom of the filter box 3, and one end of the water inlet pipe 7 passes through the interior of the MVR evaporator body 1.

[0018] like Figures 2 to 3As shown, the coarse filter plate 9, the fine filter plate 14, and the activated carbon adsorption plate 13 are adapted to the internal dimensions of the filter box 3. Limiting blocks 11 are fixedly installed on both sides of the outer wall of the coarse filter plate 9, the fine filter plate 14, and the activated carbon adsorption plate 13, and the limiting blocks 11 are slidably connected inside the fixed slide rail 8. The fine filter plate 14 has a smaller pore size than the coarse filter plate 9. Handles 12 are fixedly installed on the outer walls of the coarse filter plate 9, the fine filter plate 14, and the mounting frame 10.

[0019] By setting up a coarse filter plate 9, a fine filter plate 14, and an activated carbon adsorption plate 13, larger impurities, fine colloids, ions, and organic matter in the water are intercepted and adsorbed in sequence. This is beneficial for fully filtering the water source and avoids problems such as insufficient filtration caused by a single filter plate intercepting impurities, which can lead to internal pollution of the MVR evaporator. At the same time, the limiting block 11 can slide along the fixed slide rail 8, which is convenient for cleaning or replacement.

[0020] like Figure 4 As shown, the sealing structure 5 includes a connecting conduit 51 fixedly installed on the outer wall of the filter box 3. A limiting plate 52 is fixedly installed at one end of the connecting conduit 51. A sealing groove 53 is opened inside the limiting plate 52. A sealing gasket 54 and a sealing ring 55 are respectively provided inside the sealing groove 53. A sealing convex ring 41 is fixedly installed at one end of the water inlet pipe 4, and the sealing convex ring 41 is adapted to the size of the sealing groove 53. Both the water inlet pipe 4 and the limiting plate 52 are provided with multiple installation grooves 42 of the same size. A limiting frame 56 is fixedly installed on the outer wall of the connecting conduit 51 at a position opposite to the installation groove 42. A positioning rod 57 is fixedly installed inside the limiting frame 56. A rotating cylinder 58 is rotatably installed on the outer wall of the positioning rod 57. A locking screw 59 is fixedly installed on the outer wall of the rotating cylinder 58. A limiting cap 591 is threadedly connected to the outer wall of one end of the locking screw 59.

[0021] The sealing ring 41 on the water inlet pipe 4 and the sealing groove 53 in the limiting plate 52 are aligned and squeezed against each other, which compresses the internal sealing ring 55 and sealing gasket 54, thereby improving the sealing effect of the water inlet pipe 4 and the limiting plate 52. Then, the limiting cap 591 on the locking screw 59 limits and fixes it, avoiding problems such as leakage caused by poor sealing when the water inlet pipe 4 and the connecting conduit 51 are spliced ​​and installed.

[0022] The working principle and process of this utility model are as follows: First, by connecting the water inlet pipe 4 and the connecting conduit 51, the sealing convex ring 41 on the water inlet pipe 4 is forced to press against the sealing groove 53 in the limiting plate 52, thereby compressing and sealing the sealing ring 55 and the sealing gasket 54. When the water inlet pipe 4 and the limiting plate 52 are pressed and relatively close, by rotating the outer cylinder 58 of the positioning rod 57 in the three limiting frames 56, the rotating cylinder 58 drives the locking screw 59 to engage with the mounting groove 42 on the outer wall of the limiting plate 52 and the water inlet pipe 4. After the position is engaged, by rotating the limiting cap 591 on the outer wall of the locking screw 59, one end of it is pressed against the water inlet pipe 4, thereby securing the water inlet pipe 4 and the connecting conduit. 51. The quick splicing and fixing improves the sealing performance. After the water inlet pipe 4 is connected, water is pumped into the interior by turning on the water pump. The water source passes through the coarse filter plate 9 in the filter box 3 to filter out larger impurities and pollutants in the water. Then the filtered water passes through the fine filter plate 14 to intercept fine colloids in the water. Then it passes through the activated carbon adsorption plate 13 on the mounting bracket 10 to filter and adsorb ions and organic impurities. Finally, it is transported into the MVR evaporator through the water inlet pipe 7. After the work is completed, the operator can open the cleaning cabinet door 6 and pull the handle 12 to slide the filter plate and mounting bracket 10 on the fixed slide rail 8 using the limit block 11 for cleaning or replacement. The operation is simple.
