After the wastewater continuously exchanges heat with the evaporation component, the temperature rise rate of the evaporation component begins to slow down, and the efficiency of the wastewater evaporation treatment is reduced.

[0003] Furthermore, when the wastewater is evaporated, the wastewater is heated only by contacting the inner wall of the heating structure, and the evaporation efficiency of the wastewater is low.

[0004] During the wastewater evaporation process, after the wastewater evaporates, the evaporated wastewater forms distillation residue that adheres to the heating structure. As the wastewater evaporates, the distillation residue solidifies on the heating structure, affecting the heat exchange efficiency between the wastewater and the heating structure. The distillation residue will corrode the heating structure, affecting the service life of the heating structure. Summary of the invention

[0016] The beneficial effect of the present invention is that the present invention controls the driving motor I to drive the mounting ring to rotate, so that the wastewater repeatedly flows in the left and right evaporation components, thereby improving the evaporation efficiency of the wastewater and enhancing the efficiency of the wastewater evaporation treatment.

[0017] The present invention increases the heat exchange area of ​​the wastewater, accelerates the temperature rise rate of the wastewater, and improves the evaporation efficiency of the wastewater by allowing the wastewater to contact the inner wall of the heating chamber and the annular surface of the heating ring.

After the distillation residue is transferred to the empty slot, the distillation residue is allowed to fall from the empty slot into the storage cabin. The distillation residue is located between the guide ring I and the guide ring II, thereby reducing the amount of distillation residue remaining in the heating cabin and reducing the impact of the distillation residue on the evaporation treatment of wastewater. By setting the filter screen to an inclined state, when the filter screen pushes the distillation residue remaining in the hollow ring, the distillation residue in the hollow ring can be better pushed toward the empty slot, thereby improving the transfer effect of the distillation residue.

DETAILED DESCRIPTION

[0024] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] Example 1 A multifunctional evaporator for wastewater treatment, such as Figure 1-Figure 4 As shown, it includes a mounting frame 1, a mounting ring 2 and a storage compartment 3; two mounting frames 1 are arranged on the ground, and a driving motor Ⅰ11 is arranged on the front mounting frame 1; all mounting frames 1 are connected to the mounting ring 2 for rotation together, and the output shaft of the driving motor Ⅰ11 passes through the mounting frame 1 and is connected to the mounting ring 2; the storage compartment 3 is installed on the mounting ring 2; It also includes a water inlet pipe 4, an exhaust pipe 5 and an evaporation component; the middle of the storage compartment 3 is connected with the water inlet pipe 4; two evaporation components are installed on the storage compartment 3; all the evaporation components are connected with the exhaust pipe 5.

[0026] The evaporation component includes a heating chamber 101 and a heating ring 102; the storage chamber 3 is connected to the heating chamber 101; three heating rings 102 are installed in the heating chamber 101, and the heating rings 102 are set as conical rings.

[0027] All heating rings 102 are provided with notches 1021 to facilitate steam transfer.

[0028] The evaporation component also includes a cleaning frame 103; a driving motor II 1011 is provided on the heating chamber 101; the cleaning frame 103 is rotatably connected in the heating chamber 101, and the output shaft of the driving motor II 1011 passes through the heating chamber 101 and is connected to the cleaning frame 103, and the cleaning frame 103 is in contact with the annular surfaces of all the heating rings 102.

[0029] All cleaning racks 103 are provided with inclined surfaces to improve the cleaning effect of the distillation residue.

[0030] A plurality of collecting grooves 1031 are provided on all cleaning racks 103 to allow waste water to better contact the heating chamber 101 and the heating ring 102 .

[0031] Before using the present invention, the water inlet pipe 4 is connected to the external wastewater conveyor, and all the exhaust pipes 5 are connected to the external condensing device. The driving motor I11 is controlled to drive the mounting ring 2 to rotate, and the water inlet pipe 4, the exhaust pipe 5 and the evaporation component rotate accordingly. At this time, the storage cabin 3 and the evaporation component are in an inclined state, the evaporation component on the right is at the bottom, and the evaporation component on the left is at the top. The external wastewater conveyor is started to convey wastewater into the water inlet pipe 4, and the wastewater flows from the water inlet pipe 4 to the storage cabin 3 and the evaporation component, and the wastewater flows to the evaporation component on the right. When the amount of wastewater in the storage cabin 3 reaches 70% to 80% of the total capacity of the evaporation component, the conveying of wastewater into the water inlet pipe 4 is stopped, and the evaporation component is started to start heating the wastewater. The two evaporation components begin to heat up, and the evaporation process of the wastewater begins. The heated wastewater begins to generate steam, and the steam diffuses in the evaporation component. The diffused steam is transferred to the exhaust pipe 5, and the steam is transferred from the exhaust pipe 5 to the external condensing device.

[0032] Taking into account that during the process of heating the wastewater, the temperature of the wastewater begins to rise, and after the wastewater continuously exchanges heat with the evaporation component, the heating rate of the evaporation component begins to slow down, and the efficiency of the wastewater evaporation treatment is reduced, the drive motor Ⅰ11 is controlled to drive the mounting ring 2 to rotate, and the water inlet pipe 4, the exhaust pipe 5 and the evaporation component rotate accordingly, so that the wastewater in the right evaporation component flows to the left evaporation component. At this time, there is no wastewater in the left evaporation component, and the temperature in the left evaporation component is higher than the temperature in the right evaporation component. After the wastewater in the right evaporation component flows into the left evaporation component, the evaporation rate of the wastewater increases. The drive motor Ⅰ11 is controlled to drive the mounting ring 2 to rotate, so that the wastewater repeatedly flows in the left and right evaporation components, thereby improving the evaporation efficiency of the wastewater and improving the efficiency of the wastewater evaporation treatment.

[0033] Considering that when the wastewater is evaporated, the wastewater is only heated by contact with the inner wall of the heating structure, and the evaporation efficiency of the wastewater is low, the evaporation component consists of a heating chamber 101 and three heating rings 102. After the wastewater is transferred to the evaporation component, the wastewater is in contact with the inner wall of the heating chamber 101 and the annular surface of the heating ring 102, thereby increasing the heat exchange area of ​​the wastewater, accelerating the heating speed of the wastewater, and improving the evaporation efficiency of the wastewater.

[0034] Considering that the heating ring 102 will block the steam and affect the transfer of the steam, a notch 1021 is provided on the heating ring 102 so that the steam can be directly transferred upward to the exhaust pipe 5 and then to the external condensing device, thereby facilitating the transfer of the steam.

[0035] Considering that in the process of wastewater evaporation, after the wastewater evaporates, the evaporated wastewater forms distillation residues that adhere to the inner wall of the heating chamber 101 and the annular surface of the heating ring 102. As the wastewater evaporates, the distillation residues solidify on the inner wall of the heating chamber 101 and the annular surface of the heating ring 102, affecting the heat exchange efficiency between the wastewater and the heating chamber 101 and the heating ring 102, and the distillation residues will corrode the heating chamber 101 and the heating ring 102, affecting the service life of the heating chamber 101 and the heating ring 102, by adding a cleaning rack 103 in the inner wall of the heating chamber 101, the cleaning rack 103 is in contact with the annular surface of the heating ring 102, and by adding a driving motor II 1011 to the heating chamber 101, the driving motor The output shaft Ⅱ1011 passes through the heating chamber 101 and is connected to the cleaning frame 103. When the waste water is evaporated, the cleaning frame 103 is driven to rotate clockwise from right to left by starting the driving motor Ⅱ1011. The cleaning frame 103 scrapes the inner wall of the heating chamber 101 and the annular surface of the heating ring 102, and scrapes off the distillation residue adhering to the inner wall of the heating chamber 101 and the annular surface of the heating ring 102. The scraped off distillation residue floats in the waste water to avoid affecting the heat exchange efficiency between the waste water and the heating chamber 101 and the heating ring 102, and reduces the corrosion of the distillation residue to the heating chamber 101 and the heating ring 102, thereby affecting the service life of the heating chamber 101 and the heating ring 102.

[0036] As the wastewater evaporates, the amount of wastewater decreases, exposing the heating chamber 101 and the upper part of the heating ring 102. The areas not in contact with the wastewater are not used, resulting in waste. By providing a collecting tank 1031 on the cleaning rack 103, during the rotation of the cleaning rack 103, the wastewater flows into the collecting tank 1031 and moves upward with the rotation of the cleaning rack 103, so that the wastewater comes into contact with the heating chamber 101 and the upper part of the heating ring 102, thereby avoiding the areas not in contact with the wastewater from not being used, resulting in waste, and at the same time accelerating the evaporation rate of the wastewater.

[0037] Example 2 On the basis of Example 1, Figure 1-Figure 3 and Figure 5 As shown, it also includes a collecting component; two collecting components are installed in the storage cabin 3; the collecting component on the right includes a guide ring I 201, a guide ring II 202, a filter frame 205 and a hollow ring 207; a guide ring I 201 and a guide ring II 202 are provided in the storage cabin 3, and guide rings I 201 and II 202 are both provided with guide arc surfaces, the guide arc surfaces are located on the opposite sides of guide rings I 201 and II 202, and a baffle plate 2021 is provided on guide ring II 202; a filter frame 205 is installed on the right side of guide ring I 201; a hollow ring 207 is fixedly connected to the left side of guide ring II 202, and the hollow ring 207 is in contact with the filter frame 205.

[0038] The collecting assembly also includes an electric guide rail 203, a moving block 204 and a filter screen 206; a hollow ring 207 is provided with an empty groove 2071; the filter frame 205 is rotatably connected to the guide ring I 201; the guide ring I 201 is provided with an electric guide rail 203; the electric guide rail 203 is slidably connected to the moving block 204, the moving block 204 is provided with a connecting strip 2041, and the connecting strip 2041 is fixedly connected to the filter frame 205; eight filter screens 206 are fixedly connected to the filter frame 205.

[0039] All the filters 206 are designed to be inclined to facilitate the transfer of the distillation residue.

[0040] It also includes a connecting belt 210 and a collection frame 211; a collection frame 211 is arranged between all the mounting frames 1; two connecting belts 210 are connected to the bottom of the storage compartment 3, the connecting belts 210 are hollow, all the connecting belts 210 are located directly below the corresponding hollow ring 207, and the bottom openings of all the connecting belts 210 are located in the collection frame 211.

[0041] As the amount of distillation residue in the storage cabin 3 and the heating cabin 101 increases, the distillation residue is continuously transferred in the storage cabin 3 and the evaporation component along with the wastewater. The distillation residue is easily accumulated on the evaporation component to affect the evaporation treatment of the wastewater. By adding a collection component in the storage cabin 3, when the wastewater carrying the distillation residue is transferred in the storage cabin 3 and the evaporation component, the distillation residue in the wastewater is restricted by the guide arc surface provided on the guide ring I 201 and the guide ring II 202, so that the distillation residue in the wastewater is easier to be concentrated together for easy collection. The distillation residue in the wastewater is intercepted by the filter frame 205 and stays in the hollow ring 207, so that the distillation residue in the right heating cabin 101 will not be transferred to the left heating cabin 101, thereby reducing the accumulation of distillation residue.

[0042] After the distillation residue is intercepted by the filter frame 205 and accumulated in the hollow ring 207, when the control drive motor I11 drives the mounting ring 2 to rotate again, the wastewater backwashes the distillation residue accumulated in the hollow ring 207, causing this part of the distillation residue to adhere to the evaporation component again, affecting the evaporation efficiency of the wastewater, by adding an electric guide rail 203 and a moving block 204 to the guide ring I 201, the moving block 204 is connected to the filter frame 205 through a connecting strip 2041, a filter screen 206 is added to the filter frame 205, and an empty groove 2071 is opened on the hollow ring 207, and the control drive motor I11 drives the mounting ring 2 to rotate again. 2 After the rotation, if the left evaporation component is rotated to the bottom and the right evaporation component is rotated to the top, the waste water is transferred from the right evaporation component to the left evaporation component. In this process, the distillation residue carried by the waste water is intercepted by the right filter frame 205. After the rotation is completed, the right electric guide rail 203 is started to drive the moving block 204 to rotate clockwise from right to left, and the filter frame 205 and the filter screen 206 rotate accordingly. The filter screen 206 pushes the distillation residue remaining in the hollow ring 207 to the direction of the empty slot 2071. After the distillation residue is transferred to the empty slot 2071, the distillation residue is pushed to the empty slot 2071. The residue falls from the empty groove 2071 into the storage chamber 3, and the distillation residue is located between the guide ring I 201 and the guide ring II 202, thereby reducing the amount of distillation residue remaining in the heating chamber 101 and reducing the influence of the distillation residue on the evaporation treatment of wastewater. After the driving motor I 11 is controlled to drive the mounting ring 2 to rotate, the wastewater flows along the lower part of the storage chamber 3 to the other end, and the shielding plate 2021 on the guide ring II 202 shields the upper area of ​​the storage chamber 3 to prevent the wastewater from flowing directly to the empty groove 2071 along the upper part of the storage chamber 3. By setting the filter screen 206 to an inclined state, the filter screen 206 shields the wastewater remaining in the hollow ring 20 7 is pushed, the distillation residue in the hollow ring 207 can be better pushed toward the empty groove 2071, thereby improving the transfer effect of the distillation residue, by adding a connecting belt 210 at the bottom of the storage cabin 3, adding a collecting frame 211 between all the mounting frames 1, and the bottom of the connecting belt 210 is located in the collecting frame 211, and all the connecting belts 210 are located directly under different hollow rings 207. After the distillation residue is transferred to the storage cabin 3, the distillation residue will be directly transferred to the connecting belt 210, and then the distillation residue will fall from the connecting belt 210 into the collecting frame 211, which is convenient for collecting and cleaning the distillation residue.

[0043] Through the above work, the present invention can improve the evaporation efficiency while having the function of removing the distillation residue without stopping the machine, making the equipment more practical.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of ​​the present application, there will be changes in the specific implementation methods and application scope.
