Technical Field
[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a petrochemical wastewater treatment and recycling equipment. Background Technology
[0002] In the field of wastewater treatment in the petrochemical industry, with the improvement of environmental protection standards and the increase in demand for resource recycling, the limitations of traditional wastewater treatment devices have become increasingly prominent. Existing technologies generally adopt filtration systems, which achieve solid-liquid separation through fixed filter plates installed in the filter chamber. The working principle is to use the pores of the filter plate to intercept solid impurities and oily substances in the wastewater.
[0003] During the use of wastewater treatment equipment, when performing deep filtration on wastewater after preliminary filtration, solid impurities gradually accumulate on the surface of the filter plates as the wastewater continues to flow in and the filtration process proceeds. This leads to a decrease in filtration efficiency and may even cause clogging. Traditional equipment typically uses a fixed filter plate design, making it difficult to thoroughly and effectively clean the filter plate surface. When cleaning is required, the filter plates often need to be manually disassembled for cleaning. This not only increases the frequency and difficulty of manual cleaning but may also affect the normal operation of the wastewater treatment equipment. In addition, the flushing components of traditional equipment can usually only flush the filter plates from a single angle, making it difficult to achieve a comprehensive flushing effect from multiple angles. As a result, solid impurities on the surface of the filter plates cannot be effectively cleaned, making it difficult to achieve comprehensive flushing from multiple angles and ensure that solid impurities on the surface of the filter plates are effectively cleaned.
[0004] Therefore, to address the aforementioned inconvenience in achieving multi-angle comprehensive rinsing of the filter plates and ensuring effective removal of solid impurities from their surface, a petrochemical wastewater treatment and recovery device can be designed. During the use of this wastewater treatment device, when performing deep filtration on the pre-filtered wastewater, two sets of symmetrically arranged filter plates efficiently intercept solid impurities in the wastewater, ensuring effective filtration as the wastewater passes through the filter chamber, thus improving the wastewater treatment quality. The design of the discharge chamber, discharge pipe, and discharge tank allows for the automatic collection and discharge of impurities intercepted by the filter plates, reducing the frequency and difficulty of manual cleaning. The coordinated use of the rinsing and adjusting components achieves multi-angle comprehensive rinsing of the filter plates, ensuring effective removal of solid impurities from their surface and extending the service life of the filter plates. Utility Model Content
[0005] In order to overcome the problem that traditional wastewater treatment devices can only flush the filter plate from a single angle during use, making it difficult to achieve a comprehensive flushing effect from multiple angles, resulting in the inability to effectively clean solid impurities on the surface of the filter plate, and thus making it inconvenient to achieve comprehensive flushing from multiple angles to ensure that solid impurities on the surface of the filter plate are effectively cleaned.
[0006] The technical solution of this utility model is as follows: a petrochemical wastewater treatment and recovery device, comprising a filter chamber, an injection port, a discharge trough, a discharge tank, filter plates, a rotating shaft, a sludge discharge chamber, a sludge discharge pipe, a sludge discharge tank, a flushing pipe, an adjusting shaft, a protective shell, an opening and closing assembly, a driving assembly, an adjusting assembly, and a flushing assembly. An injection port is provided through the top of the filter chamber, and a discharge trough is provided at the bottom inner side of the filter chamber. A discharge tank is fixedly installed at the bottom of the filter chamber. Two sets of filter plates are symmetrically arranged on both sides of the interior of the filter chamber. Two sets of rotating shafts are symmetrically arranged on both sides of the interior of the filter chamber. The filter plates are fixedly installed on the side walls of the rotating shafts. Both ends of the rotating shafts are... The filter chamber is rotatably connected to both sides of the inner wall. Two sets of sewage discharge chambers are symmetrically arranged on both sides of the bottom of the filter chamber. A sewage discharge pipe is fixedly installed at the bottom of the sewage discharge chamber, and a sewage discharge tank is fixedly installed at the lower end of the sewage discharge pipe. Two sets of flushing pipes are symmetrically arranged on both sides of the inside of the filter chamber. Two sets of adjusting shafts are symmetrically arranged at both ends of the flushing pipes. One end of the adjusting shaft is rotatably connected to the inner wall of the filter chamber. A protective shell is fixedly installed on the front side wall of the filter chamber.

An adjusting component is installed inside the protective shell. A flushing component is fixedly installed on the rear side wall of the filter chamber.
[0007] Preferably, during the use of the wastewater treatment device, when performing deep filtration on the wastewater after preliminary filtration, the wastewater is first introduced into the filter chamber through the injection port. In the filter chamber, the wastewater first encounters two sets of symmetrically arranged filter plates, ensuring effective filtration and removal of solid impurities. As the wastewater continues to flow in, the pre-filtered wastewater further flows into the discharge tank and finally converges into the discharge chamber, ready for subsequent secondary treatment or recycling. Simultaneously, when it is necessary to clean the impurities intercepted on the filter plate surface, the drive assembly is first activated to rotate in reverse, causing the left and right rotating shafts to rotate in opposite directions. This drives the two sets of filter plates to rotate synchronously and in opposite directions. When the filter plates rotate to the top of the discharge chamber, the opening and closing assembly is activated to move outwards. The filter plate moves in a straight line, at which point the top of the sludge chamber opens. Simultaneously, the flushing assembly is activated to deliver alkaline cleaning agent into the flushing pipe, which then cleans and flushes the filter plate from the top. When a full flush of the filter plate is required, the adjusting assembly is activated to drive the flushing pipes on both sides to rotate back and forth, thereby achieving a multi-angle full flush of the filter plate. In summary, this petrochemical wastewater treatment and recovery device achieves efficient wastewater treatment and effective removal of impurities through a precisely designed filtration, flushing, and sludge discharge process. Because the filter plate undergoes a 180-degree rotation and multi-angle full flush, solid impurities on the surface of the filter plate are effectively cleaned and fall into the sludge chamber. Subsequently, the impurities flow into the sludge tank through the sludge discharge pipe, achieving the collection and treatment of impurities.

[0012] Preferably, the adjustment assembly includes a hydraulic lifting rod, a connecting rod, an adjusting half gear, and an adjusting toothed plate. The hydraulic lifting rod is fixedly installed inside the protective shell, and the connecting rod is fixedly installed at the lower end of the hydraulic lifting rod.

[0014] The beneficial effects of this utility model are:
[0015] During the use of the wastewater treatment device, when performing deep filtration on the wastewater after preliminary filtration, the wastewater is first introduced into the filter chamber through the injection port. In the filter chamber, the wastewater first encounters two sets of symmetrically arranged filter plates, ensuring effective filtration and removal of solid impurities. As the wastewater continues to flow in, the pre-filtered wastewater further flows into the discharge tank and eventually converges into the discharge chamber, ready for subsequent secondary treatment or recycling. Simultaneously, when it is necessary to clean the impurities intercepted on the filter plate surface, the drive assembly is first activated to rotate in reverse, causing the left and right rotating shafts to rotate in opposite directions. This drives the two sets of filter plates to rotate synchronously and in opposite directions. When the filter plates rotate to the top of the discharge chamber, the opening and closing assembly is activated to move linearly outwards, opening the top of the discharge chamber. At the same time, the flushing assembly is activated to deliver alkaline cleaning agent into the flushing pipe, then cleans the filter plates from the top. For cleaning and rinsing, when a thorough rinsing of the filter plates is required, firstly, activating the adjustment component drives the two side rinsing pipes to reciprocate, thus achieving a multi-angle comprehensive rinsing effect on the filter plates. Due to the 180-degree rotation and multi-angle comprehensive rinsing, solid impurities on the filter plate surface are effectively cleaned and fall into the discharge chamber. Subsequently, the impurities flow into the discharge tank through the discharge pipe, achieving impurity collection and treatment. In summary, the two sets of symmetrically arranged filter plates achieve efficient interception of solid impurities in wastewater, ensuring effective filtration of wastewater as it passes through the filtration chamber, improving wastewater treatment quality. The design of the discharge chamber, discharge pipe, and discharge tank allows for automatic collection and discharge of impurities intercepted by the filter plates, reducing the frequency and difficulty of manual cleaning. The combined use of the rinsing and adjustment components achieves multi-angle comprehensive rinsing of the filter plates, ensuring effective cleaning of solid impurities on the filter plate surface and extending the service life of the filter plates.

Detailed Implementation
[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0025] Please see Figure 1 and Figure 3This utility model provides an embodiment of a petrochemical wastewater treatment and recovery device, comprising a filter chamber 1, an injection port 2, a discharge trough 3, a discharge tank 4, filter plates 5, a rotating shaft 6, a sewage discharge chamber 7, a sewage discharge pipe 8, a sewage discharge tank 9, a flushing pipe 10, an adjusting shaft 11, a protective shell 12, an opening and closing assembly, a driving assembly, an adjusting assembly, and a flushing assembly. The top of the filter chamber 1 has a through injection port 2, and the bottom inner side of the filter chamber 1 has a discharge trough 3. The bottom of the filter chamber 1 is fixedly provided with a discharge tank 4. Two sets of filter plates 5 are symmetrically arranged on both sides of the interior of the filter chamber 1, and two sets of rotating shafts 6 are symmetrically arranged on both sides of the interior of the filter chamber 1. The filter plates 5 are fixedly arranged on the side walls of the rotating shafts 6. Both ends are rotatably connected to the inner walls of the filter chamber 1. Two sets of sewage discharge chambers 7 are symmetrically arranged on the bottom sides of the filter chamber 1. A sewage discharge pipe 8 is fixedly installed at the bottom of the sewage discharge chamber 7. A sewage discharge tank 9 is fixedly installed at the lower end of the sewage discharge pipe 8. Two sets of flushing pipes 10 are symmetrically arranged on the inner sides of the filter chamber 1. Two sets of adjusting shafts 11 are symmetrically arranged at both ends of the flushing pipes 10. One end of the adjusting shaft 11 is rotatably connected to the inner wall of the filter chamber 1. A protective shell 12 is fixedly installed on the front side wall of the filter chamber 1. Two sets of opening and closing components are symmetrically arranged on the bottom inner walls of the filter chamber 1. A drive component is installed inside the protective shell 12. An adjusting component is installed inside the protective shell 12. A flushing component is fixedly installed on the rear side wall of the filter chamber 1.
[0026] Please see Figure 5 and Figure 6The drive assembly includes a drive motor 101, a drive shaft 102, a drive gear 103, a driven gear 104, a transmission chain 105, a rotating gear 106, and a transmission gear 107. The drive motor 101 is fixedly mounted on the side wall of the protective housing 12. The drive shaft 102 is located at the output end of the drive motor 101. The drive gear 103 is fixedly mounted on the side wall of the drive shaft 102. The driven gear 104 is fixedly mounted on the front side wall of the left rotating shaft 6. The transmission chain 105 is located inside the protective housing 12. 03 meshes with the inner wall of the right end of the transmission gear chain 105, and the driven gear 104 meshes with the inner wall of the left end of the transmission gear chain 105. A rotating gear 106 is fixedly installed on the side wall of the drive shaft 102, and a transmission gear 107 is fixedly installed on the front side wall of the right end rotating shaft 6. The rotating gear 106 meshes with the transmission gear 107. When the drive motor 101 is started, its output end can drive the drive shaft 102 to rotate. The drive shaft 102 can drive the drive gear 103 and the rotating gear 106 to rotate synchronously. Because the drive gear 103 meshes with the inner wall of the right end of the transmission gear chain 105, the driven gear 104 meshes with the inner wall of the left end of the transmission gear chain 105. A rotating gear 106 is fixedly installed on the side wall of the drive shaft 102, and a transmission gear 107 is fixedly installed on the front side wall of the right end rotating shaft 6. The rotating gear 106 meshes with the transmission gear 107. The inner wall of the right end of the transmission gear chain 105 meshes, so the rotation of the driving gear 103 can drive the transmission gear chain 105 to rotate. Since the driven gear 104 meshes with the inner wall of the left end of the transmission gear chain 105, the rotation of the transmission gear 107 can drive the driven gear 104 and the left rotating shaft 6 to rotate. Simultaneously, since the rotating gear 106 meshes with the transmission gear 107, the rotation of the rotating gear 106 can drive the transmission gear 107 and the right rotating shaft 6 to rotate in the opposite direction, causing the left and right sides to rotate in opposite directions. The side rotation shaft 6 rotates in the opposite direction, thereby driving the two sets of filter plates 5 to rotate synchronously and in opposite directions. The opening and closing assembly includes a drive motor 201, a drive shaft 202, and a drive gear 203. Two sets of drive motors 201 are symmetrically arranged on both sides of the bottom wall of the filter chamber 1. The output end of the drive motor 201 is provided with a drive shaft 202. The drive gear 203 is fixedly arranged on the side wall of the drive shaft 202. When the drive motor 201 is started, its output end can drive the drive gear 203 to rotate through the drive shaft 202.
[0027] Please see Figure 4 and Figure 7The opening and closing assembly also includes a receiving cavity 204, a sealing plate 205, and a guide toothed plate 206. Two sets of receiving cavities 204 are symmetrically arranged on both sides of the bottom inner wall of the filter chamber 1. A sealing plate 205 is slidably disposed inside the receiving cavity 204. A guide toothed plate 206 is fixedly disposed on the bottom wall of the sealing plate 205. A drive gear 203 meshes with the guide toothed plate 206. The rotational movement of the drive gear 203 can drive the guide toothed plate 206 to move linearly outward. The linear movement of the guide toothed plate 206 can drive the sealing plate 205 to move into the receiving trough. When the sealing plate 205 is completely moved into the receiving trough, the top of the sewage discharge chamber 7 is opened. The flushing assembly includes... The filter chamber 1 is equipped with a storage tank 301, a water pump 302, a diversion pipe 303, and a connecting hose 304. The storage tank 301 is fixedly installed on the rear side wall of the filter chamber 1. The water pump 302 is fixedly installed at the bottom of the water storage pipe. The diversion pipe 303 is fixedly installed at the bottom of the water pump 302. The connecting hose 304 is fixedly installed at the top of the flushing pipe 10. One end of the connecting hose 304 is fixedly connected to one end of the diversion pipe 303. When the water pump 302 is started, the alkaline cleaning agent in the storage tank 301 is delivered to the connecting hoses 304 on both sides through the diversion pipe 303. Then, it enters the interior of the flushing pipe 10 through the connecting hoses 304. The alkaline cleaning agent cleans and flushes the top of the filter plate 5 through these flushing holes.
[0028] Please see Figure 2 and Figure 6The adjustment assembly includes a hydraulic lifting rod 401, a connecting rod 402, an adjusting half gear 407, and an adjusting toothed plate 403. The hydraulic lifting rod 401 is fixedly installed inside the protective shell 12, and the connecting rod 402 is fixedly installed at the lower end of the hydraulic lifting rod 401. Two sets of adjusting toothed plates 403 are symmetrically arranged on both sides inside the protective shell 12. An adjusting half gear 407 is fixedly installed on the front side wall of the front adjusting shaft 11. The adjusting half gear 407 meshes with the adjusting toothed plate 403. Activating the hydraulic lifting rod 401 drives the connecting rod 402 to reciprocate up and down, which in turn drives the guide toothed plates 206 at both ends to reciprocate up and down. Since the guide toothed plates 206 mesh with the adjusting half gear 407, the reciprocating up and down movement of the guide toothed plates 206... The adjustment mechanism can drive the adjusting plate gear and adjusting shaft 11 to reciprocate, thereby driving the two side flushing pipes 10 to reciprocate, thus achieving a multi-angle comprehensive flushing effect on the filter plate 5. The adjustment assembly also includes a slide rail 404, a slide rod 405, and a slide seat 406. Two sets of slide rails 404 are symmetrically arranged on both sides inside the protective shell 12. The slide rod 405 is fixedly installed inside the slide rail 404. The slide seat 406 is installed on the side wall of the slide rod 405. The slide seat 406 is slidably connected to the slide rod 405. The inner wall of the adjusting tooth plate 403 is fixedly connected to the inner wall of the slide seat 406. Both ends of the connecting rod 402 are fixedly connected to the side walls of the two slide seats 406. The slide seat 406 can drive the guide tooth plate 206 to reciprocate up and down along the slide rod 405.
[0029] During the use of the wastewater treatment device, when the wastewater after preliminary filtration is subjected to deep filtration, the wastewater is first introduced into the filter chamber 1 through the injection port 2. In the filter chamber 1, the wastewater first encounters two sets of symmetrically arranged filter plates 5 to ensure that the wastewater can be effectively filtered and the solid impurities are removed when it passes through. As the wastewater continues to flow in, the wastewater after preliminary filtration will flow further into the discharge tank 3 and finally converge into the discharge chamber 4, ready for subsequent secondary treatment or recycling.
[0030] When it is necessary to clean the impurities intercepted on the surface of the filter plate 5, firstly, start the active motor 101, whose output end can drive the active shaft 102 to rotate. The active shaft 102 can drive the active gear 103 and the rotating gear 106 to rotate synchronously. Since the active gear 103 meshes with the inner wall of the right end of the transmission gear chain 105, the rotation of the active gear 103 can drive the transmission gear chain 105 to rotate. Since the driven gear 104 meshes with the inner wall of the left end of the transmission gear chain 105, the rotation of the transmission gear 107 can drive the driven gear 104 and the left rotating shaft 6 to rotate. At the same time, since the rotating gear 106 meshes with the transmission gear 107, the rotation of the rotating gear 106 can drive the transmission gear 107 and the right rotating shaft 6 to rotate in the opposite direction, so that the left and right rotating shafts 6 can rotate in opposite directions, thereby driving the two sets of filter plates 5 to rotate synchronously and in opposite directions.
[0031] When the filter plate 5 rotates to the top of the sewage discharge chamber 7 and is parallel to the sealing plate 205, the drive motor 201 is started. Its output end can drive the drive gear 203 to rotate through the drive shaft 202. Since the drive gear 203 meshes with the guide tooth plate 206, the rotation of the drive gear 203 can drive the guide tooth plate 206 to move linearly outward. The linear movement of the guide tooth plate 206 can drive the sealing plate 205 to move into the inside of the collection groove. When the sealing plate 205 is completely moved into the inside of the collection groove, the top of the sewage discharge chamber 7 is opened.
[0032] When the filter plate 5 is flushed, firstly, the water pump 302 is started to deliver the alkaline cleaning agent in the storage tank 301 to the connecting hoses 304 on both sides through the diversion pipe 303, and then enters the interior of the flushing pipe 10 through the connecting hoses 304. The alkaline cleaning agent cleans and flushes the top of the filter plate 5 through these flushing holes.
[0033] When the filter plate 5 needs to be thoroughly flushed, firstly, the hydraulic lifting rod 401 is activated, which drives the connecting rod 402 to reciprocate up and down. The connecting rod 402 then drives the two end slides 406 and the guide tooth plate 206 to reciprocate up and down along the slide rod 405. Since the guide tooth plate 206 meshes with the adjusting half gear 407, the reciprocating up and down movement of the guide tooth plate 206 can drive the adjusting plate gear and the adjusting shaft 11 to reciprocate and rotate, thereby driving the flushing pipes 10 on both sides to reciprocate and rotate, thus achieving a multi-angle comprehensive flushing effect on the filter plate 5.
[0034] Because the filter plate 5 is rotated 180 degrees and thoroughly flushed from multiple angles, the solid impurities on the surface of the filter plate 5 are effectively cleaned and fall into the sewage discharge chamber 7. Subsequently, the impurities flow into the sewage discharge tank 9 through the sewage discharge pipe 8, thus realizing the collection and treatment of impurities.
[0035] In summary, the two sets of symmetrically arranged filter plates 5 achieve efficient interception of solid impurities in wastewater, ensuring that the wastewater is effectively filtered when passing through the filter chamber 1, thus improving the wastewater treatment quality. The design of the discharge chamber 7, discharge pipe 8, and discharge tank 9 allows the impurities intercepted by the filter plates 5 to be automatically collected and discharged, reducing the frequency and difficulty of manual cleaning. The combined use of the flushing component and the adjustment component enables multi-angle comprehensive flushing of the filter plates 5, ensuring that solid impurities on the surface of the filter plates 5 are effectively cleaned and extending the service life of the filter plates 5.
[0036] Through the above steps, during the use of the wastewater treatment device, when performing deep filtration on the pre-filtered wastewater, the wastewater is first introduced into the filter chamber 1 through the injection port 2. In the filter chamber 1, the wastewater first encounters two sets of symmetrically arranged filter plates 5, ensuring that the wastewater can be effectively filtered and the solid impurities removed during its passage. As the wastewater continues to flow in, the pre-filtered wastewater will further flow into the drain tank 3 and finally converge into the drain chamber 4, ready for subsequent secondary treatment or recycling. At the same time, when it is necessary to clean the impurities intercepted on the surface of the filter plates 5, the drive assembly is first started to rotate in the opposite direction, so that the left and right rotating shafts 6 rotate in opposite directions, thereby driving the two sets of filter plates 5 to rotate synchronously and in opposite directions. When the filter plates 5 rotate to the top of the sewage discharge chamber 7, the opening and closing assembly is started to move in a straight line outward. At this time, the top of the sewage discharge chamber 7 is opened. At the same time, the flushing assembly is started to deliver alkaline cleaning agent into the flushing pipe 10, and then the filter plates 5 are cleaned from the top. For cleaning and rinsing, when a full rinsing of the filter plate 5 is required, firstly, activating the adjustment component can drive the two side rinsing pipes 10 to reciprocate, thereby achieving a multi-angle full rinsing effect on the filter plate 5. Due to the 180-degree rotation and multi-angle full rinsing of the filter plate 5, solid impurities on the surface of the filter plate 5 are effectively cleaned and fall into the sewage discharge chamber 7. Subsequently, the impurities flow into the sewage discharge tank 9 through the sewage discharge pipe 8, realizing the collection and treatment of impurities. In summary, through two sets of symmetrically arranged filter plates 5, efficient interception of solid impurities in wastewater is achieved, ensuring that wastewater can be effectively filtered when passing through the filter chamber 1, improving the wastewater treatment quality. The design of the sewage discharge chamber 7, sewage discharge pipe 8, and sewage discharge tank 9 allows the impurities intercepted by the filter plate 5 to be automatically collected and discharged, reducing the frequency and difficulty of manual cleaning. The combined use of the rinsing component and the adjustment component achieves multi-angle full rinsing of the filter plate 5, ensuring that solid impurities on the surface of the filter plate 5 are effectively cleaned, extending the service life of the filter plate 5.
