Description

Technical Field

[0001] This invention relates to the field of coking wastewater technology, and in particular to a coking wastewater treatment device. Background Technology

[0002] Coking wastewater is a typical industrial wastewater generated in the coking production process of steel enterprises. It mainly originates from production stages such as high-temperature carbonization of coal, cooling and purification of coal gas, and refining of coking products. It is recognized by the steel industry as a complex and extremely difficult-to-treat recalcitrant organic wastewater. This type of wastewater is characterized by high pollutant concentration, strong toxicity, deep color, and large fluctuations in water quality and quantity. The water not only contains high concentrations of conventional pollutants such as COD, ammonia nitrogen, volatile phenols, and cyanide, but also accumulates a large amount of recalcitrant toxic and harmful organic compounds such as polycyclic aromatic hydrocarbons and heterocyclic compounds. It has extremely poor biodegradability, and some pollutants have carcinogenic, teratogenic, and mutagenic properties.

[0003] Most coking wastewater treatment devices on the market require filtering the wastewater through a filter screen during pretreatment. However, the filter screen is prone to clogging during the long filtration process, making it difficult for operators to disassemble and clean, thus causing inconvenience. Therefore, a coking wastewater treatment device is needed to meet people's needs. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] Given that most coking wastewater treatment devices on the market, as described above or in the existing technology, require filtration through a filter screen during the pretreatment of coking wastewater, and that the filter screen is prone to clogging during the long filtration process, making it inconvenient for operators to disassemble and clean, thus causing inconvenience, a coking wastewater treatment device is needed to meet people's needs.

[0014] In a preferred embodiment of the coking wastewater treatment device of the present invention, the first filtration mechanism includes a fixed frame, which is fixedly installed on the side walls of both sides inside the impurity filtration tank. The side wall of the fixed frame is provided with a first rectangular groove, and the inner wall of the first rectangular groove is provided with a guide groove. A first rectangular frame is slidably arranged inside the first rectangular groove. A first steel wire filter screen is installed inside the first rectangular frame. A U-shaped tie rod is installed at the top of the first rectangular frame. First sliders are installed on the side walls at both ends of the first rectangular frame, and the first sliders cooperate with the guide grooves.

[0015] By adopting the above technical solution, the first rectangular frame can be raised and lowered inside the first rectangular groove through the cooperation of the first slider and the guide groove.

[0016] In a preferred embodiment of the coking wastewater treatment device of the present invention, the second filtration mechanism includes a fixed horizontal plate and a second rectangular trough.

An elastic component is installed at the top of the second rectangular trough, and the bottom end of the elastic component is fixedly connected to the top of the lifting block.

[0017] By adopting the above technical solution, through the design of the extrusion block, and by installing a wear-resistant pad at the bottom of the extrusion block, the extrusion block can position and fix the rectangular plate and the second steel wire filter screen.

[0019] By adopting the above technical solution, through the cooperation of the guide block and the guide rail, the T-shaped connecting rod can slide inside the fixed sleeve and squeeze the first high-pressure spring body through the guide block and the guide rail, so that the elastic recovery of the first high-pressure spring body can drive the T-shaped connecting rod to reciprocate up and down.

[0020] In a preferred embodiment of the coking wastewater treatment device of the present invention, the installation and disassembly assembly includes an installation chamber and a second rectangular hole. The installation chamber is located on the side wall of one side of the welding plate, and the second rectangular hole is located on the inner wall of the first groove.

[0021] By adopting the above technical solution, the second high-pressure spring body has good elasticity, and its elastic recovery can drive the rectangular block to slide back and forth inside the second rectangular hole.

[0022] The coking wastewater treatment device of the present invention has the following beneficial effects:

[0023] This invention firstly utilizes a first filtration mechanism, employing two sets of first wire mesh filters to remove impurities from coking wastewater. When the first wire mesh needs to be disassembled and cleaned, the U-shaped pull rod is pulled upwards. This is achieved through the interaction of the first slider and guide groove, and the interaction of the first rectangular frame and first rectangular groove. As the U-shaped pull rod is pulled upwards, it causes the first rectangular frame to slide and extend within the first rectangular groove via the first slider and guide groove, thus pulling the first rectangular frame out of the first rectangular groove and cleaning the first wire mesh.

[0024] This invention firstly utilizes a second filtration mechanism, employing a second steel wire filter screen to filter coking wastewater during sedimentation. Simultaneously, by pulling the extrusion block upwards, the T-shaped connecting rod is compressed. Through the cooperation of the guide rail and the guide block, the T-shaped connecting rod is compressed, causing the guide block to slide inside the guide rail and compress the main body of the first high-pressure spring, resulting in deformation. This prevents the extrusion block from pressing and fixing the second steel wire filter screen during its rise and fall, thus facilitating the disassembly and cleaning of the second steel wire filter screen.

[0025] This invention firstly utilizes the design of an activated carbon filter to adsorb and purify coking wastewater. Simultaneously, a rectangular block cooperates with a second rectangular hole, and by pushing a push plate, the rectangular block slides inside the second rectangular hole, compressing the second high-pressure spring body and causing deformation. This prevents the rectangular block from positioning and fixing the second slider, thereby facilitating the disassembly and replacement of the second rectangular frame and the activated carbon filter, making it convenient for operators to use.

The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0039] Example 1: Refer to Figures 1-7This is the first embodiment of the present invention, which provides a coking wastewater treatment device. This device addresses the common problem in most commercially available coking wastewater treatment devices that require filtration through a filter screen during pretreatment. However, prolonged filtration can easily lead to filter screen blockage, making disassembly and cleaning difficult and causing inconvenience. The device includes an impurity filtration tank 1, with a connecting plate 2 at one end, an aeration anaerobic tank 3 at the top of the connecting plate 2, a sedimentation tank 4 at one end of the connecting plate 2, and an adsorption purification tank 5 at one end of the sedimentation tank 4. A first filtration mechanism 6 is installed inside the impurity filtration tank 1.

[0040] Combination Figure 1 , Figure 2 and Figure 3 In an embodiment of the present invention, a first pump body 201 is installed on the side wall of one side of the connecting plate 2. The input end of the first pump body 201 is equipped with a first water suction pipe 203 connected to the impurity filter tank 1, and the output end of the first pump body 201 is equipped with a first water delivery pipe 202 connected to the aerated anaerobic tank 3. By starting the first pump body 201, the liquid inside the impurity filter tank 1 is driven to enter the interior of the aerated anaerobic tank 3 through the first water delivery pipe 202.

[0041] Combination Figure 1 , Figure 2 and Figure 3 In an embodiment of the present invention, a second pump body 301 is installed at the top of the aeration anaerobic tank 3. A second water suction pipe 302 connected to the aeration anaerobic tank 3 is installed at the input end of the second pump body 301. A second water delivery pipe 303 located above the sedimentation tank 4 is installed at the output end of the second pump body 301. A first nozzle body 304 is installed at the bottom end of the second water delivery pipe 303. By starting the second pump body 301, the liquid inside the aeration anaerobic tank 3 is driven to enter the interior of the sedimentation tank 4 through the second water delivery pipe 303 and the first nozzle body 304.

[0042] Combination Figure 1 , Figure 2 and Figure 3In an embodiment of the present invention, the first filtration mechanism 6 includes a fixing frame 601, which is fixedly installed on the side walls on both sides inside the impurity filtration tank 1. The side wall of the fixing frame 601 is provided with a first rectangular groove 602, and the inner wall of the first rectangular groove 602 is provided with a guide groove 603. A first rectangular frame 604 is slidably arranged inside the first rectangular groove 602. A first steel wire filter screen 605 is installed inside the first rectangular frame 604. A U-shaped pull rod 606 is installed at the top of the first rectangular frame 604. A first slider 607 is installed on the side walls at both ends of the first rectangular frame 604, and the first slider 607 cooperates with the guide groove 603. Through the cooperation of the first slider 607 and the guide groove 603, the first rectangular frame 604 can be raised and lowered inside the first rectangular groove 602.

[0043] The specific working principle is as follows: when it is necessary to filter coking wastewater, the first filter mechanism 6 is designed to filter impurities from the coking wastewater through two sets of first wire mesh filters 605. When it is necessary to disassemble and clean the first wire mesh filters 605, the U-shaped pull rod 606 is pulled upward. The first slider 607 and the guide groove 603 cooperate with each other, and the first rectangular frame 604 and the first rectangular groove 602 cooperate with each other. When the U-shaped pull rod 606 is pulled upward, it drives the first rectangular frame 604 to slide and move upward through the first slider 607 and the guide groove 603 inside the first rectangular groove 602, so that the first rectangular frame 604 is pulled out from inside the first rectangular groove 602, thereby cleaning the first wire mesh filters 605.

[0044] Example 2: Refer to Figures 1-7This is the first embodiment of the present invention, which provides a coking wastewater treatment device. It can achieve the same results as most coking wastewater treatment devices currently on the market. During the pretreatment of coking wastewater, a filter screen is required, but over a long period of filtration, the filter screen is prone to clogging, making disassembly and cleaning difficult for operators, thus causing inconvenience. The sedimentation tank 4 is equipped with a second filtration mechanism 7, which includes a fixed horizontal plate 701 and a second rectangular groove 704. The fixed horizontal plate 701 is fixedly installed on the side walls at both ends of the sedimentation tank 4. The top of the fixed horizontal plate 701... A rectangular plate 702 is provided at one end, and a second steel wire filter 703 is installed inside the rectangular plate 702. A second rectangular channel 704 is opened on the side walls at both ends inside the sedimentation tank 4. A lifting block 7041 is slidably arranged inside the second rectangular channel 704. A pressing block 706 is installed on the side wall of the lifting block 7041. An elastic component 705 is installed at the top of the second rectangular channel 704, and the bottom end of the elastic component 705 is fixedly connected to the top end of the lifting block 7041. Through the design of the pressing block 706, and through the wear-resistant pad installed at the bottom end of the pressing block 706, the pressing block 706 positions and fixes the rectangular plate 702 and the second steel wire filter 703.

[0045] Combination Figure 1 , Figure 4 and Figure 5 In an embodiment of the present invention, the elastic component 705 includes a fixed sleeve 7051, which is fixedly installed at the top end inside the second rectangular groove 704. A guide rail 7052 is installed on the inner wall of the fixed sleeve 7051, and a guide block 7053 is slidably disposed inside the guide rail 7052. A T-shaped connecting rod 7054 penetrating the fixed sleeve 7051 is installed on the side wall of the guide block 7053, and the bottom end of the T-shaped connecting rod 7054 is fixedly connected to the top end of the lifting block 7041. The interior of the fixed sleeve 7051... The top of the device is equipped with a first high-pressure spring body 7055, and the bottom end of the first high-pressure spring body 7055 is fixedly connected to the top end of the T-shaped connecting rod 7054. Through the cooperation of the guide block 7053 and the guide rail 7052, the T-shaped connecting rod 7054 can slide inside the fixed sleeve 7051 and squeeze the first high-pressure spring body 7055. The elastic recovery of the first high-pressure spring body 7055 can drive the T-shaped connecting rod 7054 to reciprocate up and down.

[0046] Combination Figure 1In an embodiment of the present invention, a third pump body 501 is installed on one side wall of the adsorption purification tank 5. A third water suction pipe 502 connected to the sedimentation tank 4 is installed at the input end of the third pump body 501. A third water delivery pipe 503 is installed at the output end of the third pump body 501. A second nozzle body 504 connected to the adsorption purification tank 5 is installed at one end of the third water delivery pipe 503. By starting the third pump body 501, the liquid inside the sedimentation tank 4 is driven to enter the interior of the sedimentation tank 4 through the third water delivery pipe 503 and the second nozzle body 504.

[0047] The specific working principle is as follows: when the filtered coking wastewater needs to be treated by sedimentation, the liquid inside the aeration anaerobic tank 3 is first driven by the second pump body 301 to enter the sedimentation tank 4 through the second water supply pipe 303 and the first nozzle body 304. At the same time, the coking wastewater is filtered during the sedimentation process by the design of the second filter mechanism 7 and the second steel wire filter screen 703. When the second filter mechanism 7 needs to be disassembled and cleaned, the T-shaped connecting rod 7054 is squeezed by pulling the squeezing block 706 upward. The guide rail 7052 and the guide block 7053 cooperate with each other to squeeze the T-shaped connecting rod 7054, which causes the guide block 7053 to slide inside the guide rail 7052 and squeeze the first high-pressure spring body 7055 to deform. This causes the squeezing block 706 to stop squeezing and fixing the second steel wire filter screen 703, thus facilitating the disassembly and cleaning of the second steel wire filter screen 703.

[0048] Example 3: Refer to Figures 1-7 This is the first embodiment of the present invention, which provides a coking wastewater treatment device. It can achieve the same results as most coking wastewater treatment devices currently on the market. In the pretreatment of coking wastewater, a filter screen is required, which can easily become clogged during prolonged filtration, making disassembly and cleaning difficult and causing inconvenience. The adsorption purification tank 5 has welding plates 8 installed on both sides of its inner end. Each welding plate 8 has a first groove 801 at its top. A second slider 802 is slidably disposed inside the first groove 801. A second rectangular frame 803 is installed at the top of the second slider 802. An activated carbon filter 804 is installed inside the second rectangular frame 803. An installation and disassembly assembly 805 is provided on one side wall of the welding plate 8. A first rectangular hole 8011 is opened on one end of the side wall of the first groove 801. The activated carbon filter 804 is designed to adsorb and purify the coking wastewater.

[0049] Combination Figure 1 , Figure 6 and Figure 7In an embodiment of the present invention, the installation and disassembly assembly 805 includes an installation chamber 8051 and a second rectangular hole 8052. The installation chamber 8051 is formed on the side wall of one side of the welding plate 8, and the second rectangular hole 8052 is formed on the inner wall of the first groove 801. The second rectangular hole 8052 is connected to the installation chamber 8051. A rectangular block 8053 is slidably disposed inside the second rectangular hole 8052. A second high-pressure spring body 8054 is installed at one end of the rectangular block 8053, and one end of the second high-pressure spring body 8054 is fixedly connected to the side wall of one end of the installation chamber 8051. A push plate 8055 penetrating the installation chamber 8051 is installed on the side wall of the rectangular block 8053. The second high-pressure spring body 8054 has good elasticity, and its elastic recovery can drive the rectangular block 8053 to slide back and forth inside the second rectangular hole 8052, thereby positioning the second slider 802.

[0050] The specific working principle is as follows: First, when the settled coking wastewater enters the adsorption purification tank 5 through the second nozzle body 504, the activated carbon filter 804 is designed to adsorb and purify the coking wastewater, resulting in better purification. When the activated carbon filter 804 needs to be disassembled and replaced, the sealing door of the side wall of the adsorption purification tank 5 is opened first. The rectangular block 8053 cooperates with the second rectangular hole 8052, and the push plate 8055 is pushed to drive the rectangular block 8053 to slide inside the second rectangular hole 8052 and squeeze the second high-pressure spring body 8054 to deform. This causes the rectangular block 8053 to stop sliding and fix the second slider 802, thereby allowing the second rectangular frame 803 and the activated carbon filter 804 to be disassembled and replaced, making it convenient for operators to operate.
