Description

Technical Field

[0001] This utility model belongs to the field of concrete wastewater treatment technology, and specifically relates to a concrete wastewater treatment device. Background Technology

[0002] Ready-mixed concrete is widely used in the construction industry, and ready-mixed concrete batching plants are now ubiquitous. However, because ready-mixed concrete needs to be transported by special mixer trucks, these trucks are cleaned of residual concrete on their drum walls each time they are cleaned. In today's society, where environmental awareness is increasing, this residual concrete has become a problem that urgently needs to be solved.

[0003] A search revealed a waste concrete wastewater recycling and reuse treatment system disclosed in announcement number CN208684570U. The system includes a waste material receiving trough, a sand and gravel separator connected to the outlet of the waste material receiving trough via a first pipe, and a wastewater pool group connected to the outlet of the sand and gravel separator. The wastewater pool group comprises several wastewater pools interconnected via a first overflow outlet. One of the wastewater pools is connected to a clear water pool via a second overflow outlet. The outlet of the clear water pool is connected to a water storage tank. The system is characterized in that a stirring device and a pumping device are mounted on each of the wastewater pools via supports installed at the pool openings.

[0004] The existing concrete wastewater treatment device described above uses a pump to draw water into a storage tank, where it filters the wastewater through a non-woven fabric layer, thus enabling wastewater recycling. However, in actual use, once one side of the non-woven fabric layer is clogged by filter material in the wastewater, it cannot be cleaned and maintained in a timely manner, which easily affects the wastewater treatment efficiency. Waiting for manual intervention for treatment and maintenance is a long and time-consuming process. Utility Model Content

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0007] A concrete wastewater treatment device includes: a mounting frame, a treatment box fixedly mounted on the upper end of the mounting frame by bolts, a water pump fixedly mounted on the right side of the mounting frame by bolts, the input end of the water pump being connected to the treatment box via a water pipe, a filter mechanism provided on the inner side of the front of the treatment box, a sewage pipe provided at the lower end of the treatment box, a sewage valve provided at the lower end of the sewage pipe, a flow rate sensor and a liquid level sensor respectively provided on the left side of the treatment box, a control module provided on the left side of the mounting frame, a top cover inserted into the upper end of the treatment box, connecting sleeves symmetrically welded to the outer side of the top cover, a connecting block welded to the outer side of the treatment box, the connecting block and the connecting sleeve being interlocked, the connecting sleeve being snapped into the connecting block by a connecting mechanism, a cleaning mechanism provided on the inner side of the top cover, and an overflow pipe provided on the left side of the treatment box.

[0008] The cleaning mechanism includes a main body, an inlet pipe welded to the upper end of the main body, the main body being inserted into the lower end of the top cover, the upper end of the inlet pipe slidingly penetrating the top cover and threadedly connected to a first nut, a connecting pipe welded to the lower end of the main body, and a cleaning pipe head threadedly installed at the lower end of the connecting pipe.

[0009] The connecting mechanism includes a limiting frame, which is welded to the outside of the connecting sleeve. A screw is threaded to the outside of the limiting frame. A rotating block is welded to one end of the screw. A limiting ring is welded to the outer wall of the screw. The end of the screw away from the rotating block extends movably into the inside of the connecting sleeve and engages with the connecting block.

[0010] The filtration mechanism includes a slot located on the front of the processing chamber. One end of the slot extends into the inside of the processing chamber. A frame is inserted into the inside of the slot. A filter assembly is located on the inside of the frame. A fixing plate is welded to the front of the frame and is fixedly installed on the front of the processing chamber.

[0011] As a preferred technical solution, positioning blocks are symmetrically welded to the lower end of the top cover, and the main body and the positioning blocks at the lower end of the top cover are inserted into each other.

[0012] As a preferred technical solution, a through hole is provided on one side of the connecting sleeve, a slot is provided on the outer side of the connecting block, and one end of the screw movably passes through the through hole and the slot to engage.

[0013] As a preferred technical solution, a fixing groove is provided at the front opening of the slot, a sealing element is provided on the inner side of the fixing groove, and the fixing plate is fixedly installed on the inner side of the fixing groove by bolts;

[0014] As a preferred technical solution, the filtration assembly includes a stainless steel baffle, a filter cloth, an activated carbon porous filter plate, and a grid plate. The stainless steel baffle, filter cloth, activated carbon porous filter plate, and grid plate are all disposed inside the insert frame. The filter cloth is disposed between the stainless steel baffle and the activated carbon porous filter plate, and the activated carbon porous filter plate is disposed between the filter cloth and the grid plate.

[0015] In summary, the present invention has the following main advantages:

[0016] First, when the filter mechanism in the treatment tank needs to be cleaned, the water pump stops working and the drain valve at the bottom of the treatment tank opens. The external delivery pump delivers cleaning water through the inlet pipe, which in turn delivers water to the cleaning pipe head through the connecting pipe of the main body. This allows the cleaning pipe head to perform reverse flushing and cleaning of the filter mechanism. After cleaning, the drain valve closes, and the water pump can continue to pump sewage through the filter mechanism in the treatment tank for filtration. This allows for convenient and timely maintenance of the filter mechanism and ensures the efficiency of sewage treatment.

[0017] Secondly, the connecting sleeve on the top cover and the connecting block on the processing box are inserted together. After insertion, the screw connected to the screw block is operated to make the screw threaded on the limit frame to extend and retract until the limit ring on the screw contacts the connecting sleeve. At this time, the snap-in end of the screw extends into the connecting sleeve and snaps into the connecting block. Conversely, the screw block is operated in the opposite direction to make the screw connected to the screw block extend and retract. When the limit ring on the screw moves to contact the limit frame, the snap-in end of the screw moves away from the connecting block. This makes it easy to disassemble and use the top cover on the processing box, and also makes it easy to maintain the cleaning mechanism at the bottom of the top cover and the inside of the processing box.

[0026] refer to Figures 1 to 7The concrete wastewater treatment device described in this embodiment includes: a mounting frame 1, a treatment box 2 fixedly mounted on the upper end of the mounting frame 1 by bolts, a water pump 3 fixedly mounted on the right side of the mounting frame 1 by bolts, the input end of the water pump 3 being connected to the treatment box 2 via a water pipe, a filter mechanism 15 provided on the inner side of the front of the treatment box 2, a sewage pipe 6 provided at the lower end of the treatment box 2, a sewage valve 5 provided at the lower end of the sewage pipe 6, a flow rate sensor 12 and a liquid level sensor 13 respectively provided on the left side of the treatment box 2, a control module 4 provided on the left side of the mounting frame 1, and a control module 4 inserted at the upper end of the treatment box 2. The treatment tank 2 is equipped with a top cover 7, with connecting sleeves 10 symmetrically welded to the outer side of the top cover 7. A connecting block 8 is welded to the outer side of the treatment tank 2. The connecting block 8 and the connecting sleeve 10 are connected by an insertion mechanism. The connecting sleeve 10 is snapped into the connecting block 8 via a connecting mechanism 9. A cleaning mechanism 11 is provided on the inner side of the top cover 7, and an overflow pipe 14 is provided on the left side of the treatment tank 2. The control module 4 is electrically connected to the water pump 3, the drain valve 5, the flow rate sensor 12, and the liquid level sensor 13 via wires. During use, when the water pump 3 injects water into the treatment tank 2 from bottom to top, the wastewater is filtered through the filtration mechanism 15 and then discharged from the treatment tank 2. Overflow pipe 14 discharges water. By installing a flow rate sensor 12 on each side of the filter assembly 153, when the filter cloth 1532 of the filter assembly 153 becomes clogged, the flow rate on the inlet side gradually decreases, while the flow rate on the outlet side decreases significantly. By comparing the measured values ​​of the two flow rate sensors 12, the change in flow rate can be calculated. After the signal is transmitted to the control module 4, the control module 4 analyzes and determines the degree of clogging of the filter screen. When the clogging reaches the preset threshold range of the control module 4, the control module 4 simultaneously controls the drain valve 5 to... During sewage discharge, the external cleaning mechanism 11 and its delivery pump are activated, allowing the cleaning mechanism 11 to perform reverse flushing of the filter mechanism 15 from the top cover 7 at the top of the treatment tank 2. After flushing, the sewage discharge valve 5 is closed and the water pump 3 is started to continue treating the sewage. This process does not require manual intervention, thus greatly ensuring the efficiency of sewage treatment. The liquid level sensor 13 can work with the control module 4 to monitor the highest water level in the treatment tank 2, and also facilitates the control module 4 to control the delivery of the water pump 3. The monitored water level is much higher than the overflow pipe position.

[0027] The cleaning mechanism 11 includes a main body 113, with an inlet pipe 111 welded to the upper end of the main body 113. The main body 113 is inserted into the lower end of the top cover 7. The upper end of the inlet pipe 111 slides through the top cover 7 and is threadedly connected to a first nut 112. The lower end of the main body 113 is welded to a connecting pipe 114, and the lower end of the connecting pipe 114 is threadedly fitted with a cleaning pipe head 115. During the cleaning process, an external pump delivers cleaning water through the inlet pipe 111, and the inlet pipe 111 delivers water to the cleaning pipe head 115 through the connecting pipe 114 of the main body 113, so that the cleaning pipe head 115 can perform reverse flushing and cleaning of the filter mechanism 15. During installation, the main body 113 is positioned and inserted into the lower end of the top cover 7. Then, the inlet pipe 111 at the upper end of the main body 113 slides through the top cover 7 and is locked with the first nut 112, which makes it convenient to install and use the cleaning mechanism 11.

[0028] The connecting mechanism 9 includes a limiting frame 903, which is welded to the outside of the connecting sleeve 10. A screw 901 is threadedly connected to the outside of the limiting frame 903. A rotating block 902 is welded to one end of the screw 901. A limiting ring 904 is welded to the outer wall of the screw 901. The end of the screw 901 away from the rotating block 902 extends movably into the inside of the connecting sleeve 10 and engages with the connecting block 8. The connecting sleeve 10 on the top cover 7 and the connecting block 8 on the processing box 2 are inserted together. After insertion, the rotating block 902 is operated to connect the rotating block 902. The screw 901 extends and retracts threadedly on the limiting bracket 903 until the limiting ring 904 on the screw 901 contacts the connecting sleeve 10. At this time, the snap-in end of the screw 901 extends into the connecting sleeve 10 and snaps into the connecting block 8. Conversely, the rotating block 902 is operated in the opposite direction, so that the screw 901 connected to the rotating block 902 extends and retracts. When the limiting ring 904 on the screw 901 contacts the limiting bracket 903, the snap-in end of the screw 901 moves away from the connecting block 8, so that the top cover 7 can be easily disassembled and used on the processing box 2.

[0029] The filtration mechanism 15 includes a slot 151, which is located on the front of the treatment tank 2. One end of the slot 151 extends into the inside of the treatment tank 2. A frame 152 is inserted into the inside of the slot 151. A filter assembly 153 is provided on the inside of the frame 152. A fixing plate 154 is welded to the front of the frame 152. The fixing plate 154 is fixedly installed on the front of the treatment tank 2. After the frame 152 is inserted into the slot 151 of the treatment tank 2, the filter assembly 153 in the frame 152 can easily filter impurities in the wastewater.

[0030] refer to Figure 3 The lower end of the top cover 7 is symmetrically welded with positioning blocks 21. The main body 113 and the positioning blocks 21 at the lower end of the top cover 7 are inserted into each other. Using the positioning blocks 21 on the top cover 7, the main body 113 of the cleaning mechanism 11 can be conveniently positioned and inserted from the lower end of the top cover 7.

[0031] The limit frame 903 is also provided with a round hole, so that one end of the screw 901 can pass through the wall of the limit frame 903 through the round hole.

[0032] refer to Figure 2 and Figure 3 and Figure 6 A through hole 20 is provided on one side of the connecting sleeve 10, and a slot 18 is provided on the outer side of the connecting block 8. One end of the screw 901 is movably inserted through the through hole 20 and the slot 18 to engage. In use, when the through hole 20 on the connecting sleeve 10 and the slot 18 on the connecting block 8 overlap, the screw 901 can be easily operated to extend into the connecting sleeve 10 and engage in the slot 18.

[0033] refer to Figure 5 A fixing groove 17 is provided at the front opening of the slot 151. A sealing element 16 is provided on the inner side of the fixing groove 17. The fixing plate 154 is fixedly installed on the inner side of the fixing groove 17 by bolts. The fixing groove 17 at the slot 151 can be used to easily install and fix the fixing plate 154 of the insert frame 152. During the fixing process, the sealing element 16 in the fixing groove 17 is squeezed when the fixing plate 154 is installed, so that a seal is formed between the fixing plate 154 and the processing box 2.

[0034] refer to Figure 7 The filter assembly 153 includes a stainless steel mesh 1531, a filter cloth 1532, an activated carbon porous filter plate 1533, and a grid plate 1534. The stainless steel mesh 1531, filter cloth 1532, activated carbon porous filter plate 1533, and grid plate 1534 are all located inside the insert frame 152. The filter cloth 1532 is positioned between the stainless steel mesh 1531 and the activated carbon porous filter plate 1533. The activated carbon porous filter plate 1533 is positioned between the filter cloth 1532 and the grid plate. Between the plates 1534; after being installed on the treatment tank 2 by the insert frame 152, the sewage flows from bottom to top through the treatment tank 2, passing through the grid plate 1534, the activated carbon porous filter plate 1533 and the filter cloth 1532 in sequence for layer-by-layer filtration, which can treat the sewage. The stainless steel baffle 1531 can limit the side of the filter cloth 1532 away from the activated carbon porous filter plate 1533, so as to avoid excessive deformation of the filter cloth 1532 during use.

[0035] Operating principle and advantages: During operation, when water pump 3 pumps water into treatment tank 2 from bottom to top, the wastewater is filtered through filter mechanism 15 and discharged through overflow pipe 14 on treatment tank 2. By installing a flow rate sensor 12 on each side of filter assembly 153, when the filter cloth 1532 of filter assembly 153 becomes clogged, the flow rate on the inlet side gradually decreases, while the flow rate on the outlet side decreases significantly. By comparing the measured values ​​of the two flow rate sensors 12, the change in flow rate can be calculated. The signal is transmitted to control module 4 and then processed by control module 4. The system analyzes and determines the degree of clogging of the filter screen. When the clogging reaches the preset threshold range of the control module 4, the control module 4 controls the drain valve 5 to drain the sewage and starts the external cleaning mechanism 11 delivery pump. The external delivery pump delivers cleaning water through the inlet pipe 111, and the inlet pipe 111 delivers water to the cleaning pipe head 115 through the connecting pipe 114 of the main body 113, so that the cleaning pipe head 115 can perform reverse flushing and cleaning of the filter mechanism 15. After flushing is completed, the drain valve 5 is closed and the water pump 3 is started at the same time to continue treating the sewage.

[0036] The connecting sleeve 10 on the top cover 7 and the connecting block 8 on the processing box 2 are inserted together. After insertion, the rotating block 902 is operated to make the screw 901 connected to the rotating block 902 extend and retract on the limiting frame 903 until the limiting ring 904 on the screw 901 contacts the connecting sleeve 10. At this time, the snap-in end of the screw 901 extends into the connecting sleeve 10 and snaps into the connecting block 8. Conversely, the rotating block 902 is operated in the opposite direction to make the screw 901 connected to the rotating block 902 extend and retract. When the limiting ring 904 on the screw 901 contacts the limiting frame 903, the snap-in end of the screw 901 moves away from the connecting block 8, and the top cover 7 can be disassembled and used on the processing box 2.
