Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and more specifically to an energy-saving biochemical treatment device. Background Art

[0002] Biochemical treatment equipment is a device that uses microbial metabolism to purify sewage. It converts organic pollutants into harmless substances by simulating the biological degradation process in nature. Mud-water separation is an indispensable part of biochemical treatment. It is responsible for effectively separating the treated sludge from clean water to ensure that the effluent quality meets the standards.

[0003] In addition to pre-treatment such as coarse screens and fine screens to remove large debris, the current water treatment equipment also has preliminary sedimentation tanks and secondary sedimentation tanks for solid-liquid separation, and aerobic biological reaction structures for aerobic biological reaction treatment.

[0004] The Chinese patent application with authorization announcement number: CN217367358U discloses a mud-water separator for water treatment, which can conveniently remove silt and sand from the water, saves time and effort, and improves the efficiency of water treatment.

[0005] The above patent still has the following deficiencies:

[0006] During the solid-liquid separation process, the accumulation of solid particles will cause the filter to gradually become clogged, which not only affects the filtration efficiency, but also requires the operator to frequently clean the filter; each cleaning requires additional energy to drive the operation of related equipment, which will directly increase energy consumption, making the entire process not energy-efficient. In addition, the scraper or other tools used in the cleaning process will inevitably cause a certain degree of physical wear to the filter when they contact and move with the filter surface. Over time, this repeated friction will accelerate the aging and even damage of the filter material, shortening its service life; and for those parts that have not yet been clogged, such cleaning is actually unnecessary because it does not solve any actual problems, but instead increases maintenance costs and workload.

[0007] Therefore, an energy-saving biochemical treatment device is proposed. Summary of the invention

[0020] Furthermore, a first connecting rope made of elastic material is fixedly installed in the pressure relief hole, and a spoiler block is fixedly installed on the first connecting rope; the diameter of the pressure relief hole gradually decreases as it moves away from the isolation sleeve.

[0021] Furthermore, an upper sleeve is evenly installed on the bottom wall of the collection basket, and the distance between the upper sleeve and the bottom wall of the water tank is the same as the diameter of the water inlet;

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0042] Embodiment 1:

[0043] See also Figures 1 to 7 , an energy-saving biochemical treatment device, comprising a water tank 1, on which a water inlet is provided;

[0044] An isolation sleeve 2 is fixedly installed on the inner bottom wall of the water tank 1, and the water inlet is connected to the isolation sleeve 2; sewage is injected into the isolation sleeve 2 through the water inlet, and impurities sink in the water at this time. As the liquid level in the isolation sleeve 2 rises, the clean water in the upper layer of the isolation sleeve 2 will pass over the top wall of the isolation sleeve 2 and flow downward along the outer wall of the isolation sleeve 2, and gradually flow into the space between the outer wall of the isolation sleeve 2 and the inner wall of the water tank 1, thereby achieving the effect of separating impurities from water; in the process of water in the isolation sleeve 2 overflowing outward, since the circumference of the isolation sleeve 2 is greater than the circumference of the water inlet, the water flow velocity overflowing from the isolation sleeve 2 can be reduced, and the impact force on impurities suspended in the water is reduced, ensuring that the suspended impurities have enough time to settle, reducing the probability of suspended impurities flowing out of the isolation sleeve 2 with the water flow, and improving the purification effect.

[0045] A filter screen 3 is installed on the inner wall of the isolation sleeve 2, and the filter screen 3 improves the filtering effect of impurities suspended in the water, thereby improving the separation effect of the substance and water.

[0046] The side wall of the isolation sleeve 2 is evenly provided with through grooves, and a first slider 4 is slidably installed in the through groove. The first slider 4 moves up and down along the through groove. An inner slide plate 5 is installed on the first slide plate 4, which is in contact with the inner side wall of the isolation sleeve 2. The inner slide plate 5 covers the surface of the through groove, so that the sewage in the isolation sleeve 2 can be prevented from leaking through the through groove. A connecting rod 6 is provided on the top wall of the inner slide plate 5, and a shovel plate 7 is fixedly installed on the top of the connecting rod 6. The shovel plate 7 is used to remove impurities on the surface of the filter screen 3, and a driving component matched with the shovel plate 7 is provided on the first slider 4. When impurities adhere to the surface of the filter screen 3 and cause the filter screen 3 to be blocked, the driving component drives the shovel plate 7 located below the blocked part to move upward. At this time, the shovel plate 7 moves along the surface of the filter screen 3, so that the impurities on the surface of the filter screen 3 can be cleaned and the permeability of the filter screen 3 is ensured; and under the action of the connecting rod 6, there is a gap between the shovel plate 7 and the inner slide plate 5. Therefore, after the impurities are removed, the water flows through the filter screen 3 normally. At this time, under the action of the driving component, the shovel plate 7 moves down and resets to prepare for cleaning the filter screen 3 again.

[0047] An outer slide plate 8 that fits with the outer wall of the isolation sleeve 2 is fixedly mounted on the side wall of the first slide block 4, a cavity 9 is formed on the outer slide plate 8, a pressure relief hole 10 is formed on the side wall of the cavity 9, and a pressurizing mechanism that cooperates with the cavity 9 is provided on the isolation sleeve 2; when the filter screen 3 is blocked, as the outer slide plate 8 moves upward, the pressurizing mechanism continues to provide water to the cavity 9, so when the pressure relief hole 10 moves to the surface of the filter screen 3, the clean water discharged from the pressure relief hole 10 will pass through the filter screen 3, thereby exerting an impact force on the impurities stuck in the filter screen 3, so that the impurities are out of contact with the filter screen 3, and the auxiliary shovel plate 7 cleans the filter screen 3;

[0048] A collecting basket 11 is provided in the water tank 1, and the bottom wall of the collecting basket 11 is at the same horizontal plane as the bottom wall of the filter screen 3, and the top wall of the collecting basket 11 is located between the liquid surface and the top wall of the filter screen 3, and the collecting basket 11 is located in the isolation sleeve 2; therefore, when the shovel plate 7 moves on the surface of the filter screen 3, the side wall of the shovel plate 7 fits with the side wall of the collecting basket 11, and the impurities shoveled off at this time will fall into the collecting basket 11, reducing the impurity content in the water, reducing the probability of the filter screen 3 being blocked again, and improving the efficiency of solid-liquid separation; the edge of the top wall of the shovel plate 7 is symmetrically fixed with a partition 12, and the partition 12 can be set to limit the flow direction of the impurities shoveled off by the shovel plate 7, preventing the impurities from entering the isolation sleeve 2 again, and further improving the solid-liquid separation effect.

[0049] like Figure 3 As shown, a water baffle 13 is fixedly installed on the side wall of the outer slide plate 8, and a groove is provided on the top wall of the water baffle 13, which is used to store water, thereby increasing the weight of the water baffle 13; a drainage hole 14 is provided on the bottom wall of the groove, when the amount of water entering the groove is greater than the amount of water discharged by the drainage hole 14, the weight of the water baffle 13 increases, and when the amount of water entering the groove is less than the amount of water discharged by the drainage hole 14, the weight of the water baffle 13 decreases; and an elastic bellows 15 is installed between the top wall of the through groove and the first slider 4, when the groove is full of water, under the action of gravity, the first slider 4 is located at the bottom of the through groove, and the elastic bellows 15 is in a stretched state, when the water in the groove is gradually emptied, the elastic bellows 15 contracts and drives the first slider 4 to move upward, thereby driving the shovel plate 7 to move; and the water baffle 13 is always located below the shovel plate 7, so after cleaning, it is ensured that the water can flow into the groove, which plays a role in ensuring that the water baffle 13 can be reset.

[0050] When the filter screen 3 is not blocked, the water flowing downward along the outer wall of the isolation sleeve 2 flows to the surface of the outer slide plate 8, and then flows into the groove on the water baffle plate 13. At this time, the drainage speed of the drainage hole 14 is lower than the speed of the water flow entering the groove, so the weight of the water baffle plate 13 increases rapidly. At this time, the water baffle plate 13 drives the first slide block 4 to move down to the bottom end of the through groove, and the water in the groove overflows through the surface of the water baffle plate 13. Therefore, when the filter screen 3 is not blocked, the shovel plate 7 is out of contact with the filter screen 3;

[0051] When the filter 3 is clogged, the amount of water in the groove below the clogged portion of the filter 3 is less than the amount of water discharged from the drainage hole 14 on the bottom wall of the groove, and the pressure of the water baffle 13 on the elastic bellows 15 is reduced, so the elastic bellows 15 recovers and pulls the first slider 4 upward, so that the shovel plate 7 can be driven to move through the cooperation of the water baffle 13 and the drainage hole 14.

[0052] Through the cooperation of the water retaining plate 13, the elastic bellows 15 and the first slider 4, the filter screen 3 can be cleaned when the filter screen 3 is blocked. Compared with continuous cleaning of the filter screen 3, the wear degree of the filter screen 3 and the shovel plate 7 is reduced, which plays a role in saving costs.

[0053] like Figure 6 As shown, a plug hole is provided on the top wall of the inner slide plate 5, and a connecting rod 6 is vertically slidably inserted into the plug hole, and an elastic member 16 is installed between the connecting rod 6 and the bottom wall of the plug hole;

[0054] A mounting groove is provided on the inner side wall of the isolation sleeve 2, in which a stopper 17 is slidably installed. The side wall of the stopper 17 away from the mounting groove is an arc surface. A spring 18 is installed between the stopper 17 and the mounting groove, and the elastic coefficient of the spring 18 is greater than the elastic coefficient of the elastic member 16.

[0055] When the shovel plate 7 is not in contact with the stopper 17, the stopper 17 extends out of the mounting groove under the action of the spring 18. Therefore, when the shovel plate 7 moves upward, the shovel plate 7 will be blocked by the stopper 17. Since the elastic coefficient of the spring 18 is greater than the elastic coefficient of the elastic member 16, when the shovel plate 7 is blocked, the elastic member 16 will be squeezed. At this time, the shovel plate 7 is in a stationary state, and the inner slide plate 5 continues to move upward until the connecting rod 6 is completely retracted into the insertion hole. At this time, the shovel plate 7 is in contact with the inner slide plate 5, and the elastic bellows 15 is The elastic coefficient of is greater than the elastic coefficient of spring 18, so the shovel plate 7 continues to apply an upward thrust to the block 17. Under the action of the arc surface on the block 17, the block 17 is subjected to a horizontal thrust, so the spring 18 is squeezed and the block 17 will retract into the mounting groove. At this time, the elastic member 16 recovers and pushes the linkage rod and the shovel plate 7 to move upward quickly, so that the shovel plate 7 can apply an impact force to the impurities attached to the surface of the filter 3, scrape off the impurities on the surface of the filter 3, and improve the cleaning effect of the filter 3.

[0056] In addition, the water discharged from the pressure relief hole 10 will impact the impurities attached to the surface of the shovel plate 7, so that the impurities on the surface of the shovel plate 7 flow to the surface of the collection basket 11 along with the water flow, thereby reducing the content of impurities in the water inside the isolation sleeve 2 and improving the solid-liquid separation effect.

[0057] like Figure 6As shown, the pressurizing mechanism includes a catheter 19 fixedly inserted on the elastic bellows 15, the catheter 19 is an elastic tube, and the catheter 19 extends into the cavity 9. During the extension of the elastic bellows 15, the cavity 9 is in a negative pressure state under the action of the catheter 19; during the contraction of the elastic bellows 15, the cavity 9 is in a high pressure state under the action of the catheter 19; a one-way valve 20 is embedded on the top wall of the cavity 9; therefore, when the elastic bellows 15 is in a negative pressure state, the elastic bellows 15 will absorb water from the top wall of the outer skateboard 8 through the catheter 19 and the one-way valve 20, and at this time, part of the water flowing through the surface of the outer skateboard 8 will be absorbed by the elastic bellows 15, so when the elastic bellows 15 contracts, it can provide water to the cavity 9 and pressurize the water.

[0058] like Figure 6 As shown, a first connecting rope 21 made of elastic material is fixedly installed in the pressure relief hole 10, and a spoiler block 22 is fixedly installed on the first connecting rope 21. During the stretching and recovery process of the elastic bellows 15, the spoiler block 22 is not subjected to impact force. At this time, the first connecting rope 21 pulls the spoiler block 22 to fit the side wall of the pressure relief hole 10, thereby ensuring that the one-way valve 20 can absorb water normally; the diameter of the pressure relief hole 10 gradually decreases as it moves away from the isolation sleeve 2. Therefore, during the drainage process of the pressure relief hole 10, the spoiler block 22 is out of contact with the side wall of the pressure relief hole 10 and shakes in the pressure relief hole 10, thereby expanding the diffusion range of the water discharged from the pressure relief hole 10 and improving the cleaning effect of the filter 3.

[0059] like Figure 4 As shown, an upper sleeve 23 is evenly installed on the bottom wall of the collection basket 11, and the distance between the upper sleeve 23 and the bottom wall of the water tank 1 is the same as the diameter of the water inlet;

[0060] The lower sleeve 24 is evenly installed on the inner bottom wall of the water tank 1, and the upper sleeve 23 and the lower sleeve 24 are spaced apart.

[0061] Furthermore, the distance between the lower sleeve 24 and the bottom wall of the collecting basket 11 is the same as the diameter of the water inlet.

[0062] Therefore, the water discharged from the water inlet will gradually pass through the gap between the upper sleeve 23 and the lower sleeve 24. In this process, the water flow speed can be reduced by friction, ensuring that impurities in the water flow have enough time to settle, reducing the probability of impurities contacting the filter 3; and finally making the water in the water tank 1 overflow evenly from the top wall of the isolation sleeve 2, reducing the overflow rate of the water flow, reducing the impact force between the impurities and the filter 3, and reducing the probability of impurities being stuck in the filter 3; and it can reduce the impact force of the water flow discharged from the water inlet on the water flow overflowing from the top wall of the isolation sleeve 2, further improving the stability of the water flow around the top wall of the isolation sleeve 2.

[0063] like Figure 5As shown, a sieve plate 25 is fixedly installed between the side walls of the upper sleeve 23 and the lower sleeve 24, so that it can play the role of fixing the collection basket 11. The diameter of the holes on the sieve plate 25 is larger than the diameter of the holes in the filter 3, so that impurities can pass through the filter 3, and when the impurities pass through the sieve plate 25, the impurities and the water flow both contact and rub with the holes on the sieve plate 25, thereby reducing the horizontal speed of the water flow and impurities, reducing the probability of impurities getting stuck in the filter 3, and playing a role in improving the cleaning effect of the filter 3.

[0064] like Figure 5 As shown, a reciprocating screw 26 is rotatably mounted on the sieve plate 25, a second slider 27 is threadedly mounted on the reciprocating screw 26, and an impeller 28 is mounted on the end of the reciprocating screw 26. Therefore, the reciprocating screw 26 rotates during the process of water flow impacting the impeller 28, and the second slider 27 reciprocates up and down on the reciprocating screw 26. An impact block 29 is movably sleeved on the reciprocating screw 26, and the impact block 29 is driven by the second slider 27. The impact block 29 is used to apply a downward impact force to the sieve plate 25. At this time, the impurities in contact with the sieve plate 25 are subjected to the downward impact force. Under the action of the impact force, the sedimentation rate of the impurities is accelerated, and the probability of the impurities contacting the filter screen 3 is reduced.

[0065] like Figure 5 As shown, an elastic block 30 is fixedly installed on the bottom wall of the second slider 27, and the elastic block 30 is fixedly connected to the impact block 29, so that the second slider 27 can drive the impact block 29 to move, and when the impact block 29 hits the screen plate 25 downward, the elastic block 30 is squeezed, and the second slider 27 can continue to move downward, thereby ensuring that the impact block 29 can exert an impact force on the screen plate 25.

[0066] like Figure 4 As shown, a sponge 31 is fixedly installed on the inner wall of the water tank 1; when the impurities are moved downward by the impact force and contact the sponge 31 on the inner bottom wall of the water tank 1, the sponge 31 is deformed, so as to absorb the kinetic energy of the impurities, and prevent the impurities from being suspended in the water again under the action of the reaction force, thereby reducing the content of impurities suspended in the water; and some impurities will contact the sponge 31 on the inner wall of the water tank 1 during the suspension process, and the impurities are stuck in the sponge 31 on the side wall of the water tank 1, further reducing the content of impurities suspended in the water, and reducing the frequency of cleaning the filter 3;

[0067] A sleeve 32 is inserted into the collection basket 11 , and the top wall of the sleeve 32 is in the same plane as the top wall of the collection basket 11 , so that it is convenient for the staff to clean the sediment on the bottom wall of the water tank 1 .

[0068] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
