If the filter screen is damaged after long-term use, it needs to be replaced in time to avoid affecting the use of the evaporator. Most existing filter screens are fixed with bolts, which is troublesome to replace. Therefore, we provide an MVR evaporator water treatment equipment to solve the above problems. Utility Model Content

[0025] This utility model provides an MVR evaporator water treatment device.

[0026] Please see Figure 1 and Figure 2 The MVR evaporator, including the evaporator body 1, mainly evaporates and condenses about 90% to 98% of the wastewater in oil / water, hydrocarbon / water mixtures, and waste emulsions into wastewater. The concentrated liquid enters the intermittent pyrolysis furnace for thermal cracking treatment. No waste gas is generated during the MVR evaporation process, making it a new type of high-efficiency and energy-saving evaporation equipment.

[0027] A condenser tube 7 is fixedly connected to the outer surface of the evaporator body 1. A condenser assembly 8 is fixedly installed on the outside of the condenser tube 7. The condenser tube 7 is connected to a wastewater recycling device to facilitate the recycling and reuse of water resources and reduce water waste. The condenser assembly 8 can condense the evaporated water vapor, so that the water vapor becomes liquid again and flows into the collection device through the condenser tube 7.

[0028] A drain pipe 9 is fixedly connected to the outer surface of the evaporator body 1. An electric valve 10 is fixedly installed inside the drain pipe 9. The drain pipe 9 is connected to an intermittent pyrolysis furnace, which facilitates the transport of the concentrated liquid after evaporation to the intermittent pyrolysis furnace for pyrolysis treatment. The electric valve 10 can control the flow rate of the medium inside the drain pipe 9, which facilitates the subsequent processing of the concentrated liquid.

[0029] Please see Figure 2An evaporation assembly 6 is fixedly installed inside the evaporator body 1. The evaporation assembly 6 is used to evaporate wastewater and provides treatment for mixed liquids such as oil / water, hydrocarbon / water mixtures, and waste emulsions. The electrical components involved in this application are all prior art and will not be described in detail here. The drawings in this application are only for reference, and the specific style and installation position should be based on the actual situation.

[0030] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The evaporator body 1 is internally connected to a pull-out mounting box 2. The pull-out mounting box 2 is equipped with a handle on the outside. The operator can pull the pull-out mounting box 2 out of the evaporator body 1 through the handle and disassemble and replace the filter plate 3 in the pull-out mounting box 2. After the replacement is completed, the pull-out mounting box 2 can be put back into the evaporator body 1 through the handle. The end of the pull-out mounting box 2 has a certain magnetic attraction, which can produce a relatively stable magnetic attraction effect with the surface of the evaporator body 1, so that the pull-out mounting box 2 can be stably placed inside the evaporator body 1. The pull-out mounting box 2 and the evaporator body 1 have good airtightness, which can prevent wastewater or water vapor from flowing out through the gap between them.

[0031] Please see Figure 2 , Figure 3 and Figure 4 The evaporator body 1 is internally fixedly connected to a fixed bracket 5. The pull-out mounting box 2 slides inside the fixed bracket 5. The fixed bracket 5 provides stable support for the installation of the pull-out mounting box 2 and also limits the pull-out mounting box 2 to prevent it from shaking under the impact of wastewater, thus improving the stability of the device.

[0032] The pull-out mounting box 2 is internally connected to a filter plate 3. The filter plate 3 has a set of filter holes inside, which can filter out impurities carried in the wastewater and prevent impurities from entering the high-temperature evaporation area with the water and affecting the evaporation process of the device. The pull-out mounting box 2 has a groove inside that matches the filter plate 3. When the filter plate 3 slides into the pull-out mounting box 2, it will be locked inside the groove, thus keeping the filter plate 3 stable. After the filter plate 3 is locked into the groove, there is no gap between the two.

[0033] Please refer to it again. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The pull-out mounting box 2 is equipped with a limiting mechanism 4, which includes a control rod 401. An auxiliary lever 406 is fixedly connected to the outer surface of the control rod 401. The auxiliary lever 406 allows the operator to easily move the control rod 401. When the control rod 401 is lifted by force, it will cause the limiting rod 402 to rise, thereby releasing the fixation of the filter plate 3. At this time, the filter plate 3 can be pulled out of the pull-out mounting box 2 for replacement. The limiting mechanism 4 provides great convenience for the replacement of the filter plate 3, and also provides a stable limiting effect for the filter plate 3.

[0034] Please see Figure 5 The bottom surface of the control lever 401 is fixedly connected to the limiting rod 402. The inside of the pull-out mounting box 2 is provided with a cavity 403. The limiting rod 402 slides inside the cavity 403. The cavity 403 includes an upper slide rail and a lower insertion hole. The end of the filter plate 3 is also provided with a limiting slot that matches the cavity 403. When the limiting rod 402 passes through the filter plate 3 and is inserted into the insertion hole, the limiting rod 402 will limit the filter plate 3, thereby stabilizing the filter plate 3 inside the pull-out mounting box 2. Three limiting rods 402 and other structures are provided to improve the fixing effect of the limiting mechanism 4 on the filter plate 3.

[0035] A limiting sliding ring 404 is fixedly connected to the outer surface of the limiting rod 402. The limiting sliding ring 404 is slidably connected to the cavity 403. The limiting sliding ring 404 provides support and stability for the sliding lifting of the limiting rod 402, and provides appropriate compression space for the telescopic spring 405, so that the telescopic spring 405 can normally push the limiting rod 402 to be stably inserted into the insertion hole, thereby making the filter plate 3 stably snapped into the pull-out mounting box 2.

[0036] A telescopic spring 405 is sleeved on the outer surface of the limiting rod 402. The two ends of the telescopic spring 405 are fixedly connected to the pull-out mounting box 2 and the limiting sliding ring 404, respectively. The elastic potential energy of the telescopic spring 405 is sufficient to push the limiting rod 402 to reset, thereby maintaining the limiting effect of the limiting rod 402 on the filter plate 3. The small amplitude of shaking caused by the characteristics of the telescopic spring 405 itself is within the acceptable range of this application and will not cause the limiting rod 402 to disengage from the insertion hole.

[0037] Working principle: The operator first discharges the solution requiring water treatment into the evaporator body 1, then starts the evaporation assembly 6. The filter plate 3 filters the solution entering the evaporator body 1, preventing impurities from affecting subsequent evaporation operations. The evaporation assembly 6 evaporates the wastewater in the mixed solution into water vapor. The water vapor is condensed into liquid by the condenser assembly 8 and transported to the recovery equipment via the condenser pipe 7. The concentrated liquid after evaporation is transported to the intermittent pyrolysis furnace for thermal decomposition via the drain pipe 9. When replacing the filter plate 3, the operator first pulls the pull-out installation box 2 out of the evaporator body 1 using the handle. Then, by pulling up the control lever 401 using the auxiliary lever 406, the control lever 401 is forced to raise the limiting insert 402, thereby disengaging it from the limiting slot at the end of the filter plate 3. At this point, the auxiliary lever 406 can be released and the filter plate 3 can be removed from the pull-out mounting box 2. Then, the control lever 401 is pulled up again and the new filter plate 3 is inserted into the pull-out mounting box 2. After releasing the lever, the limiting insert 402 will be reset under the push of the telescopic spring 405, thereby inserting into the limiting slot at the end of the filter plate 3 to complete the fixation of the filter plate 3. Finally, the operator can restart the device to treat the water by pushing the pull-out mounting box 2 into the evaporator body 1.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
