[0041] In order to make the purpose, technical solutions and advantages of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Unless otherwise defined, the technical terms or scientific terms used herein should be understood by people with general skills in the field of the present invention. The words "including" and similar words used in this article mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects.

[0042] The structure of an evaporative sewage treatment device in the prior art includes a distillation box 100 and a water inlet box 200 connected to the distillation box 100. The water inlet box 200 is fixed on a support frame 300. A steam circulation pipe 400 is provided on the top of the distillation box 100. Figure 1 As shown, it can be seen that the evaporative sewage treatment device of the existing invention patent can only realize the efficient utilization of heat and the function of preheating the sewage before evaporation treatment, and does not have the effect of recycling and reusing water resources.

[0043] In view of the problems existing in the prior art, the embodiments of the present invention provide a sewage evaporation treatment device for water resource recovery and reuse, such as Figure 3 As shown, the water resource recovery and reuse sewage evaporation treatment device includes a support frame 3, and a water inlet box 2 arranged on the support frame 3, a distillation box assembly 1 is arranged on the upper plate surface of the water inlet box 2, a steam circulation pipe 4 is arranged on the top of the distillation box assembly 1, and a water resource recovery pipe 5 is arranged in communication with the side wall of the distillation box assembly 1, and the free end of the water resource recovery pipe 5 is connected to the water resource recovery tank 6, and the water resource recovery tank 6 is fixedly arranged on the bottom plate of the water inlet box 2 and on the support frame 3. In this embodiment, the arrangement of the combined structure of the water resource recovery pipe 5 and the water resource recovery tank 6 can recycle and reuse water resources in the process of sewage evaporation treatment, which can avoid the waste of water resources and reduce production costs at the same time.

[0044] The existing distillation box 200 includes a condensation plane 011, which is arranged on a box cover 012, and a box body 013 that can be matched with the box cover 012. The box body 013 is provided with a cylindrical cavity 014 inside. Figure 2 As shown, it can be seen that the condensation plane 011 and the cavity 014 of the existing distillation box 200 do not have the function of condensing water. Therefore, the structure of the existing distillation box 200 is not conducive to the recycling and reuse of water resources.

[0045] In order to solve the above problems, in one implementation, Figure 4 As shown, the distillation box assembly 1 includes a distillation box body 14, and a box cover 11 that can be buckled on the upper end opening of the distillation box body 14, a condensation plate 12 is fixedly arranged on the inner top wall of the box cover 11, and a trumpet-shaped condensation portion 13 is provided on the condensation plate 12, and a steam duct 16 is fixedly arranged on the side wall of the box cavity 15 of the distillation box body 14, and the steam duct 16 divides the distillation box body 14 into two upper and lower separated inner cavities, and a trumpet-shaped inclined portion 17 is provided on the outer side wall of the steam duct 16, and the inclined portion 17 is matched with the condensation portion 13. When the box cover 11 is installed on the distillation box body 14, part of the inclined portion 17 extends into the condensation portion 13.

[0046] exist Figure 4 In the example, the distillation box in the present invention is provided with a combination structure of a condensation plate 12 and a condensation part 13 on the box cover 11, and a combination structure of a steam duct 16 and an inclined part 17 is provided in the distillation box body 14. The setting of this combination structure can realize the condensation of steam, thereby realizing the recycling and reuse of water resources.

[0047] It is worth noting that the condensation section 13 can be a groove-cavity structure. The setting of the condensation section 13 can make the condensation plate 12 present a positive bowl-shaped structure. Of course, in other examples, the condensation section 13 is not limited to the groove-cavity structure; the setting of the inclined portion 17 can make the steam duct 16 present a trumpet-shaped structure as a whole. Such a structure can make the steam duct 16 better cooperate with the condensation section 13.

[0048] During operation, after the box cover 11 and the distillation box body 14 are installed, the steam conduit 16 will extend into the condensation part 13, and the condensation part 13 will not contact the outer side wall of the steam conduit 16. At this time, a condensation gap will be formed between the outer side wall of the condensation part 13 and the steam conduit 16. When steam enters the condensation gap from bottom to top through the steam conduit 16, it will contact the outer side wall of the condensation part 13 and the steam conduit 16, so that the steam can be condensed into liquid, which is convenient for water resource recycling and reuse. In order to achieve a better condensation effect of the condensation part 13 and the steam conduit 16, it should be noted that the steam conduit 16 and the condensation plate 12 are both made of metal.

[0049] When steam condenses into liquid water through the condensation gap, some solid pollutants in the sewage will condense into the liquid water along with the steam. If the solid pollutants are reused along with the liquid water, it will cause secondary pollution.

[0050] In order to solve the above problems, in one implementation, Figure 5As shown, the water resource recycling and reuse sewage evaporation treatment device also includes a filter assembly 7, which is arranged below the steam conduit 16. The filter assembly 7 includes a support plate 71 with one end fixedly connected to the lower end of the steam conduit 16 and the other end fixedly connected to the inner wall of the distillation box body 14. The support plate 71 and the inner wall of the distillation box body 14 form a distilled water collection chamber 72 with an upper part open and other parts closed. The transverse section of the support plate 71 is provided with N distilled water collecting chambers 72 connected to the distilled water collecting chamber 72. A water flow hole 73 is connected to the collecting chamber 72, and a filter body 74 is arranged in the upper opening of the distilled water collecting chamber 72. A blocking plate 75 is fixedly connected to the lower end surface of the support plate 71, and the free lower end of the blocking plate 75 is fixedly connected to the inner wall of the distillation box body 14, wherein a drainage chamber 76 is formed between the transverse section of the support plate 71, the blocking plate 75 and the inner wall of the distillation box body 14, and the drainage chamber 76 is connected to the water resource recovery pipe 5, and N is a positive integer greater than or equal to 1.

[0051] The setting of the filter assembly 7 can effectively collect and filter the solid pollutants in the liquid water, thereby preventing the solid pollutants from entering the condensed water and avoiding secondary pollution.

[0052] In one example, Figure 5 As shown, the number of the water holes 73 can be set within 1-100, and 1-100 water holes 73 are distributed in a matrix on the same horizontal plane. In this example, the aperture of the water hole 73 is 5-10 mm. The setting of this aperture can completely remove solid pollutants in the condensed water; in another example, the number of the water holes 73 is set to more than 100. In this example, the aperture of the water hole 73 is less than 5 mm, and a plurality of water holes 73 are distributed in a matrix on the same horizontal plane. In this example, the setting of the plurality of water holes 73 can assume the function of a filter net due to the small aperture setting, thereby achieving the effect of secondary filtration, making the condensed water cleaner.

[0053] During operation, the condensed water flows downward through the condensation gap (the condensed water and / or hangs on the inclined portion 17 and the condensation portion 13), and enters the distilled water collection chamber 72 after being filtered through the filter body 74, and then enters the water drainage chamber 76 through the water flow hole 73, and is finally introduced into the water resource recovery tank 6 through the water resource recovery pipe 5.

[0054] In order to prevent some solid pollutants in the sewage from moving with the steam, in one embodiment, Figure 6As shown, the water resource recovery and reuse sewage evaporation treatment device also includes a gas-liquid separation mechanism 8 arranged above the steam conduit 16, and the gas-liquid separation mechanism 8 includes a gas-liquid separation body 81 fixedly connected to the steam conduit 16, and the upper end of the gas-liquid separation body 81 is fixedly connected to a gas-liquid separation slave body 82, and the gas-liquid separation slave body 82 is a trumpet-shaped structure, and the upper end opening size of the gas-liquid separation slave body 82 is larger than the lower end opening size, wherein the gas-liquid separation body 81, the gas-liquid separation slave body 82 and the steam conduit 16 are connected and arranged.

[0055] The setting of the gas-liquid separation mechanism 8 can play the role of a separator, which is used to separate the steam after the wastewater evaporates and the unevaporated wastewater, ensuring that the steam can be effectively guided to the next effect or condenser. This design helps to improve the efficiency of the system because it can reduce the carryover of liquid in the steam pipeline, thereby avoiding affecting the operation of subsequent equipment. Through the design of the gas-liquid separation mechanism 8, the solid pollutants in the sewage can be effectively reduced from flowing with the steam, and the efficiency and water quality of water resource recycling and reuse can be improved.

[0056] Specifically, the working principle of the design of the gas-liquid separation mechanism 8 is mainly to utilize the difference in physical properties of the gas-liquid two-phase, such as density, speed, etc., and to achieve the separation of the two through a specific structure and operation mode. For example, gas will float due to its low density, while liquid will sink due to its high density. In the specific implementation process, a partition plate or filler can be set in the gas-liquid separation mechanism 8 to increase the gas-liquid contact area to promote the separation effect. In addition, different forms of the structure of the gas-liquid separation mechanism 8 can also be designed according to specific process requirements, which will not be repeated here.

[0057] During the filtering process, solid pollutants will be deposited on the upper surface of the filter body 74 due to the filtering effect. Long-term operation will block the mesh holes of the filter body 74, which is not conducive to the filtering function of the filter body 74. At the same time, the traditional manual disassembly and cleaning of the equipment is frequently carried out, which is extremely inconvenient, time-consuming and labor-intensive, and requires downtime, reducing production efficiency.

[0058] In order to solve the above problems, in one implementation, Figure 7 and Figure 8As shown, the water resource recovery and reuse sewage evaporation treatment device also includes a cleaning mechanism 9, which includes a cleaning brush 91 that contacts the filter body 74, and a first connecting rod 92 is fixedly connected to the upper end surface of the cleaning brush 91, and the free end of the first connecting rod 92 is fixedly connected to the outer wall of the fixing ring 93, and the fixing ring 93 is fixedly sleeved outside the spiral rod 94, and the spiral rod 94 is movably inserted in the rotating ring 95, and a second connecting rod 96 is fixedly connected to the outer wall of the rotating ring 95, and the free end of the second connecting rod 96 is fixedly connected to the inner wall of the distillation box body 14, and the spiral rod 94 is externally threaded with an inner spiral tube 97, and the inner spiral tube 97 is fixedly inserted on the sealing plate 98, and the sealing plate 98 is circumferentially fixedly sleeved with a sealing ring 99, and the sealing ring 99 and the inner wall of the gas-liquid separation body 81 are slidably arranged with each other.

[0059] The setting of the cleaning mechanism 9 can clean the upper surface of the filter body 74 to prevent solid pollutants deposited on the filter body 74 from clogging the mesh holes of the filter body 74; and the structural design of the cleaning mechanism 9 is simple and reasonable, and can clean the filter body 74 in real time without manual cleaning and frequent cleaning. It can be cleaned when the equipment is running, which can save time and effort and improve production efficiency. At the same time, the working process of the cleaning mechanism 9 does not require an external power source, and can be driven by the steam pressure, which can greatly reduce production costs.

[0060] During operation, the steam pressure pushes the sealing plate 98 to move upward in the gas-liquid separation body 81. Since the inner spiral tube 97 is threadedly connected to the spiral rod 94, the movement of the sealing plate 98 will cause the spiral rod 94 to rotate through the inner spiral tube 97. The rotation of the spiral rod 94 will cause the cleaning brush 91 to rotate in the forward direction through the first connecting rod 92 and the fixing ring 93. The rotation of the cleaning brush 91 will realize the cleaning process of the upper surface of the filter body 74.

[0061] When the air pressure resistance is lost, in order to enable the sealing plate 98 to be reset to the initial position, and at the same time, when the filter body 74 is cleaned again, in one embodiment, as Fig. 9As shown, the cleaning mechanism 9 also includes a guide support assembly 910, one end of which is fixedly connected to the lower end surface of the sealing plate 98 and the other end of which is fixedly connected to the upper end surface of the support plate 911. The support plate 911 is fixedly arranged on the inner wall of the steam duct 16, wherein the guide support assembly 910 includes a guide support rod 9101, a guide support cylinder 9102 and a guide support spring 9103. The guide support rod 9101 is movably inserted in the guide support cylinder 9102, and the guide support spring 9103 is wound around the outside of the guide support rod 9101. The two ends of the guide support spring 9103 are respectively fixedly connected to the side wall of the guide support rod 9101 and the outer wall of the guide support cylinder 9102.

[0062] The arrangement of the combined structure of the support plate 911 and the guide support assembly 910 can make the sealing plate 98 move up and down only in the vertical direction. At the same time, when the sealing plate 98 loses the air pressure resistance of the steam, power will be provided to reset the sealing plate 98 to its initial position. Due to the pulling of the guide support assembly 910, the sealing plate 98 will move downward and rotate in the opposite direction with the cleaning brush 91, thereby cleaning the filter body 74. Specifically, when the sealing plate 98 moves into the gas-liquid separation body 82, the inner wall of the gas-liquid separation body 82 does not contact the sealing plate 98 and the sealing ring 99. At this time, the steam moves upward from the gap between the sealing ring 99 and the inner wall of the gas-liquid separation body 82, so that the upward resistance force on the sealing plate 98 is smaller than the downward pulling force of the guide support assembly 910, thereby causing the sealing plate 98 to reset downward.

[0063] Since the cleaning mechanism 9 has a reasonable structural design, during the sewage treatment process, as long as steam exists, the above cleaning process can be repeated. Therefore, in actual implementation, after all the sewage is treated, the solid contaminants on the filter body 74 can be cleaned, or the solid contaminants on the filter body 74 can be cleaned after multiple times.

[0064] In order to prevent the steam from moving upward from the connection between the spiral rod 94 and the inner spiral tube 97, so that the air pressure is insufficient and the sealing plate 98 cannot move upward, in one embodiment, as shown in FIG. Fig. 9As shown, the water resource recovery and reuse sewage evaporation treatment device also includes an anti-leakage mechanism 10, and the anti-leakage mechanism 10 includes an anti-leakage cylinder 101 covered outside the spiral rod 94 and the inner spiral tube 97, the upper end of the anti-leakage cylinder 101 is fixedly connected to the lower end surface of the sealing plate 98, and a guide cone 102 is fixedly connected to the lower end of the anti-leakage cylinder 101, and the tip of the guide cone 102 is arranged away from the anti-leakage cylinder 101, and a first step 103 and a second step 104 are arranged in the anti-leakage cylinder 101, and the first step 103 and the second step 104 are respectively matched with the inner spiral tube 97 and the spiral rod 94.

[0065] The provision of the anti-leakage mechanism 10 in this embodiment can effectively prevent the steam from moving upwards from the connection between the spiral rod 94 and the inner spiral tube 97 over the sealing plate 98 .

[0066] Since the thrust of steam is very large, in the actual working process, the thrust of steam will cause the lower end of the spiral rod 94 to hit the second step 104, and the inner spiral tube 97 to hit the first step 103. On the one hand, the problem of equipment damage occurs due to the impact force. On the other hand, due to excessive squeezing, the spiral rod 94 cannot rotate relative to the sealing plate 98. In one embodiment, as shown in FIG. Fig.10 As shown, the water resource recovery and reuse sewage evaporation treatment also includes a buffer mechanism 110, and the buffer mechanism 110 includes a supporting cylinder 111 movably arranged in the anti-leakage cylinder 101, and the first surface 112 of the supporting cylinder 111 forms the first step 103, and the second surface 113 of the supporting cylinder 111 forms the second step 104. A plurality of buffer springs 114 are fixedly arranged on the lower end surface of the supporting cylinder 111, and the lower end of the buffer spring 114 is fixedly connected to the upper end surface of the rotating shaft 115, and the rotating shaft 115 is rotatably arranged on the inner bottom wall of the anti-leakage cylinder 101.

[0067] In this embodiment, the buffer mechanism 110 can buffer the impact force and protect the equipment. At the same time, since the rotating shaft 115 can rotate relative to the anti-leakage cylinder 101, the buffer mechanism 110 can be used to enable the spiral rod 94 to always rotate relative to the sealing plate 98.

[0068] During the process of the cleaning mechanism 9 cleaning the filter body 74, solid pollutants may accumulate in a small area of ​​the filter body 74. In order to avoid the cleaning brush 91 from being stuck due to the accumulation,

[0069] In one embodiment, Fig.11 and Fig.12As shown, the water resource recovery and reuse sewage evaporation treatment device also includes a support mechanism 130 that can support the filter body 74 to move vertically in the distilled water collection chamber 72. The support mechanism 130 is provided in a plurality of numbers.
