[0003] Traditional mixed wastewater treatment primarily relies on physical methods, involving direct filtration and sedimentation in a settling tank to allow pollutant-containing particles to settle at the bottom. Subsequent flotation is also required, a cumbersome and inefficient process. Existing technologies utilize heating to effectively separate volatile substances, dissolved solids, and water from the mixed wastewater, improving treatment efficiency. However, in practice, the heating process generates a large amount of steam, which existing devices directly release, causing thermal pollution and reducing the device's practicality.

A connecting rod is fixedly connected to the right side of the outer wall of the scraper. A sealing strip is fixedly connected to the right side of the outer wall of the condenser box.

[0008] As a further description of the above technical solution:

[0009] An installation box is fixedly connected to the top of the condenser box, and an alarm light is fixedly connected to the inner wall of the installation box.

[0010] As a further description of the above technical solution:

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, a cooling medium is supplied to the connecting pipe by a refrigerator, and the circulation pump promotes the flow of the cooling medium in the connecting pipe and the cooling pipe, thereby realizing efficient heat exchange between the cooling medium and the steam in the condenser, so that the steam is condensed into liquid, preventing thermal pollution to the environment.

This circulating cooling method improves the cooling efficiency.

[0022] 2. In this utility model, by setting a filter screen on the top of the inner wall of the condenser, larger particulate impurities in the steam can be effectively intercepted, ensuring the smooth progress of subsequent processing. When cleaning impurities, the operator pushes the scraper to scrape the impurities to the drain port. Under normal conditions, the compression spring tightens the sealing plate to close the drain port. When the impurities reach a certain amount, the spring force is overcome to open the drain port and discharge the impurities. After cleaning is completed, the spring rebounds to close the drain port. This design realizes automatic sewage discharge, reduces the burden of manual cleaning, and the sealing strip enhances the sealing performance to prevent steam or impurities from leaking, thereby ensuring the stable operation of the device and improving processing efficiency and quality.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of a mixed wastewater treatment circulating condensation device, comprising a condensation tank 1, a steam interface 3 fixedly connected to the top of the condensation tank 1 for introducing steam generated from the mixed wastewater to be treated, a cooling pipe 4 fixedly connected to the inner wall of the condensation tank 1 for heat exchange with the steam to condense the steam, a water distribution pipe 5 fixedly connected to the bottom left side of the outer wall of the condensation tank 1 for diverting the condensed liquid, a connecting pipe 6 connected to the top left side of the outer wall of the water distribution pipe 5 for transmitting cooling medium, the other end of the connecting pipe 6 connected to the cooling pipe 4, a circulating pump 7 connected to the outer wall of the connecting pipe 6 for driving the cooling medium to circulate, a cooler 8 fixedly connected to the left side of the outer wall of the condensation tank 1 for providing cooling medium to the connecting pipe 6, and a collection box 9 fixedly connected to the bottom of the outer wall of the condensation tank 1 for collecting the condensed liquid. The outer left bottom of the water distribution pipe 5 is connected to a water supply pipe 10, which is used to transport a portion of the condensate to the collection tank 9. The bottom end of the water supply pipe 10 is connected to the collection tank 9. The outer right bottom of the collection tank 9 is connected to a drain pipe 11, which is used to drain the condensate in the collection tank 9. The inner wall of the condensation tank 1 is equipped with a filter mechanism 2, which is used to filter impurities in the mixed wastewater. The top of the condensation tank 1 is fixedly connected to an installation box 12, which is used to install an alarm light 13. The inner wall of the installation box 12 is fixedly connected to the alarm light 13, which is used to issue a warning when the device malfunctions. The outer right side of the collection tank 9 is equipped with an information plate 15, which is used to provide relevant information about the collection tank 9. The outer walls of the information plate 15 are all threaded with screws 16, which are used to fix the information plate 15 to the collection tank 9. The information plate 15 is threaded to the collection tank 9 by the screws 16.

[0032] Specifically, the steam generated from the mixed wastewater to be treated enters the condenser 1 through the steam interface 3. The refrigeration unit 8 operates, providing a cooling medium to the connecting pipe 6. The circulation pump 7 starts, causing the cooling medium to flow in the connecting pipe 6 and enter the cooling pipe 4. The cooling medium in the cooling pipe 4 exchanges heat with the steam in the condenser 1, and the steam gradually condenses into liquid. The condensed liquid collects at the bottom of the condenser 1. Part of it flows into the collection tank 9 through the water distribution pipe 5 and the water supply pipe 10 for collection. The other part, under the action of the circulation pump 7, returns to the cooling pipe 4 through the connecting pipe 6 to continue participating in the cooling process, thereby improving the cooling efficiency. The condensate collected in the collection tank 9 can be discharged through the drain pipe 11 for subsequent treatment or utilization. When an abnormality occurs in the condenser 1, the alarm light 13 illuminates to alert the operator that an inspection and handling are required. It is fixed to the right side of the outer wall of the collection tank 9 by screws 16 to provide relevant information about the collection tank 9. The operator uses this information to accurately manage the wastewater in the collection tank 9 and arrange subsequent treatment.

[0033] Reference Figure 1 , Figure 4 and Figure 5 The filtration mechanism 2 includes a filter screen 201, which is fixedly connected to the top of the inner wall of the condenser box 1. The filter screen 201 is used to intercept larger particulate impurities in the steam. A drain port 202 is provided on the front side of the outer wall of the condenser box 1 to discharge the filtered impurities. A sealing plate 203 is rotatably connected to the front side of the outer wall of the condenser box 1. The sealing plate 203 is used to close the drain port 202 under normal conditions. Multiple compression springs 204 are fixedly connected at equal intervals on both the left and right sides of the front end of the outer wall of the condenser box 1. The other end of each compression spring 204 is fixedly connected to the sealing plate 203. The compression springs 204 are used to provide elastic force to maintain the seal. Plate 203 remains closed. A scraper 205 is slidably connected to the top of filter screen 201. The scraper 205 is used to scrape impurities on filter screen 201 to drain port 202. A connecting rod 206 is fixedly connected to the right side of the outer wall of scraper 205. The connecting rod 206 is used to push scraper 205 to move. A sealing strip 207 is fixedly connected to the right side of the outer wall of condenser box 1. The sealing strip 207 is used to enhance the sealing of condenser box 1. An anti-slip handle 14 is fixedly connected to the outer wall of connecting rod 206. The anti-slip handle 14 is used to facilitate the operator to push connecting rod 206. The surface of anti-slip handle 14 is treated with anti-slip material to prevent slipping during operation.

[0034] Specifically, when steam enters the condenser 1 through steam inlet 3, it first passes through the filter screen 201 located at the top of the inner wall of the condenser 1. The filter screen 201 intercepts larger particulate impurities carried in the steam. As the device operates, impurities gradually accumulate on the filter screen 201. When the filter screen 201 needs to be cleaned, the operator holds the connecting rod 206, which is fixedly connected to the right side of the outer wall of the scraper 205, and pushes the scraper 205 forward on top of the filter screen 201. During the sliding process, the scraper 205 scrapes the impurities accumulated on the filter screen 201 together. When the scraper 205 moves to the front, the impurities are pushed to the vicinity of the drain port 202. Under normal conditions, the sealing plate 203 is blocked by the left and right sides of the front end of the outer wall of the condenser 1. Multiple compression springs 204 are pressed tightly, keeping the drain port 202 closed. When impurities exert sufficient pressure on the sealing plate 203, they overcome the elasticity of the compression springs 204, causing the sealing plate 203 to open and the impurities to be discharged from the drain port 202. After cleaning, the scraper 205 is released, the compression springs 204 rebound, and the sealing plate 203 closes the drain port 202 again, ensuring the normal operation of the condenser box 1. The sealing strip 207 is used to enhance the sealing performance between the condenser box 1 and the sealing plate 203 to prevent steam or impurities from leaking. The surface of the anti-slip handle 14 is treated with anti-slip material, which increases the friction between the hand and the handle, making it easier, more stable, and more accurate for the operator to push or pull the connecting rod 206.

[0035] Reference Figure 1 , Figure 2 and Figure 4 The bottom of the collection tank 9 is fixedly connected to four feet 17, which are used to support and stabilize the collection tank 9. Each foot 17 has pre-drilled holes 18 around its bottom, which are used to fix the collection tank 9 in a specific position using bolts or similar means. An observation frame 19 is fixedly connected to the front of the outer wall of the collection tank 9. The observation frame 19 is used to install a transparent plate 20, and the inner wall of the observation frame 19 is also fixedly connected to the transparent plate 20. The transparent plate 20 is used to observe the liquid level and condition inside the collection tank 9. A controller 21 is fixedly connected to the middle right side of the outer wall of the condenser tank 1. The controller 21 is used to control the operation of the circulating pump 7 and the cooler 8. The controller 21 is electrically connected to the circulating pump 7 and the cooler 8 respectively to achieve precise control over them.

[0036] Specifically, the feet 17 support and stabilize the collection box 9. The pre-drilled holes 18 around the bottom can be used to fix the collection box 9 in a specific position with bolts, etc., to enhance its stability and prevent movement during operation. The transparent plate 20 inside the observation frame 19 allows the operator to intuitively observe the liquid level and state of the condensate inside the collection box 9 without opening it, so as to understand the collection situation in time. The controller 21, as the control center, is electrically connected to the circulating pump 7 and the cooler 8 respectively. According to the preset program or the information fed back by the sensor, it adjusts and controls the operating speed of the circulating pump 7 and the power of the cooler 8, so as to achieve precise control of the entire condensation process and ensure the efficient and stable operation of the device.

[0037] Working principle: Before using the device, the steam generated by the mixed wastewater to be treated first enters the condenser 1 through the steam interface 3. At this time, the cooler 8 provides the cooling medium to the connecting pipe 6. The circulation pump 7 starts to make the cooling medium flow in the connecting pipe 6 and enter the cooling pipe 4. The cooling medium in the cooling pipe 4 exchanges heat with the steam in the condenser 1, causing the steam to condense into liquid. The condensate accumulates at the bottom of the condenser 1. Part of it enters the collection tank 9 through the water distribution pipe 5 and the water supply pipe 10. The other part is driven by the circulation pump 7 to return to the cooling pipe 4 through the connecting pipe 6 to continue cooling to improve efficiency. The condensate collected in the collection tank 9 can finally be discharged from the drain pipe 11 for subsequent treatment or utilization.

[0038] When steam enters the condenser 1 through the steam inlet 3, it first passes through the filter screen 201 located at the top of its inner wall. This filter screen 201 intercepts larger particulate impurities in the steam. As the steam runs, impurities accumulate on the filter screen 201. During cleaning, the operator holds the connecting rod 206, which is fixedly connected to the right side of the outer wall of the scraper 205, and pushes the scraper 205 forward to scrape the impurities together. When the scraper 205 moves to the front, the impurities are pushed to the vicinity of the drain port 202. Under normal conditions, the sealing plate 203 is pressed tightly by multiple compression springs 204 on the left and right sides of the front end of the outer wall of the condenser 1 to close the drain port 202. When the impurities generate enough pressure to overcome the elasticity of the compression springs 204, the sealing plate 203 opens, and the impurities are discharged from the drain port 202. After cleaning, the scraper 205 is released, and the compression springs 204 rebound, causing the sealing plate 203 to close the drain port 202 again, ensuring the normal operation of the condenser 1. The sealing strip 207 enhances the sealing performance between the condenser 1 and the sealing plate 203, preventing steam or impurities from leaking.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
