Description

Technical Field

[0001] The present invention relates to the technical field of circulating water treatment, and particularly to an automatic circulating water treatment device. Background Art

[0002] Circulating water treatment is a key link in realizing the efficient utilization of water resources in industrial production. It aims to purify the water used in the industrial production process so that it can be reused in the production process to achieve the goal of water resource recycling. In this process, various methods such as physical, chemical, and biological methods are comprehensively used to remove various impurities, dissolved substances, and microorganisms in the water to ensure that the treated water quality strictly meets the specific requirements of the production process.

[0003] In the actual operation of circulating water treatment, adding flocculant is a very common and effective means. The mechanism of action of the flocculant is to cause the wastes in the circulating water to aggregate with each other to form flocs with larger particle sizes that can be filtered. Subsequently, the circulating water containing flocs can be filtered through a filtering device, and then the flocs can be removed to achieve the preliminary purification of the water quality.

[0004] In related technologies, such as Chinese Patent CN206549533U, an automatic dosing circulating water system for flocculant is disclosed. The automatic dosing circulating water system for flocculant includes a stirring barrel, stirring tentacles, and a semi-permeable membrane. During use, first, the water to be treated is added into the stirring barrel, and then the water to be treated is stirred by the stirring tentacles. At the same time, the flocculant is scattered into the interior of the stirring barrel through the holes on the stirring tentacles to cause the wastes in the water to aggregate with each other, and then the water is filtered through the semi-permeable membrane.

[0005] However, there are also some problems in the actual filtration process of existing filtering devices: during long-term use, the filtering structure will inevitably be blocked by impurities, flocs, etc. in the water. Once the filtering structure is blocked, its filtering performance will drop sharply or even completely lose the filtering function. At this time, in order to restore the normal filtering ability of the filtering structure, it is necessary to take measures to stop the machine, clean the blocked filtering structure or directly replace it with a new filtering structure. This coping method not only consumes a large amount of time and labor costs but also causes the operation of the entire circulating water system to be interrupted, seriously affecting the continuity and work efficiency of industrial production. Summary of the Invention

[0006] Based on this, it is necessary to provide an automatic circulating water treatment device to solve the problems of poor filtration continuity and low filtration efficiency in the current circulating water treatment process.

[0007] The above object is achieved by the following technical solutions:

[0008] A circulating water automatic treatment device, which comprises:

[0009] A housing having a water inlet and a water outlet;

[0010] A flocculant adder disposed on the housing and configured to add flocculant into the housing;

[0011] A central cylinder inserted into the housing. The central cylinder is simultaneously communicated with the water inlet and the water outlet. Two spiral grooves are provided on the central cylinder. The two spiral grooves have opposite spiral directions, are connected end to end, and form a closed movement path;

[0012] A corrugated pipe inserted between the housing and the central cylinder. The corrugated pipe can rotate around its own axis and can also deform along its own axis direction. The two ends of the corrugated pipe are respectively rotatably arranged on the housing and the central cylinder. The corrugated pipe is provided with first filter holes;

[0013] A base ring inserted between the central cylinder and the corrugated pipe and fixedly connected to the corrugated pipe. The base ring divides the space between the central cylinder and the corrugated pipe into two chambers; A sliding part is inserted on the inner peripheral wall of the base ring. The sliding part can slide in the radial direction and has corresponding first and second positions before and after sliding. When in the first position, the sliding part is disengaged from the spiral groove. When in the second position, the sliding part forms a sliding fit with the spiral groove; A plurality of blades are provided on the outer peripheral wall of the base ring. The plurality of blades are arranged circumferentially and are all located outside the corrugated pipe;

[0014] A driving mechanism configured to provide a driving force for the rotation of the corrugated pipe;

[0015] An adjusting mechanism configured to switch the position of the sliding part.

[0016] Further, the central cylinder can rotate around its own axis; The driving mechanism includes a driving member, a first gear, a second gear and an internal gear ring. The driving member is configured to provide a driving force for the rotation of the central cylinder; The first gear is fixedly sleeved on the central cylinder; The second gear is disposed on the housing and can rotate around its own axis and meshes with the first gear; The internal gear ring is disposed on the housing and can rotate around its own axis and is fixedly connected to the corrugated pipe. The internal gear ring meshes with the second gear.

[0017] Further, the sliding part is made of a magnetic material; the position adjusting mechanism includes a first elastic member and an electromagnet. The first elastic member is disposed between the base ring and the sliding part, and under the action of the first elastic member, the sliding part has a tendency to move inward; the electromagnet is inserted into the base ring and can form a magnetic connection with the sliding part when energized, and can drive the sliding part to move outward.

[0018] Further, the first elastic member is a compression spring.

[0019] Further, the spiral groove has two symmetrically arranged spiral sub-grooves; each spiral sub-groove has two spiral sub-slots with different pitches, and the spiral sub-slot with a smaller pitch in the same spiral sub-groove is located inside the spiral sub-slot with a larger pitch.

[0020] Further, the circulating water automatic treatment device further includes an impurity removal mechanism configured to clean the flocs in the housing.

[0021] Further, the impurity removal mechanism includes a rotating ring, a rack, a collection chamber, a collection housing, a third gear, and a second elastic member. The rotating ring is inserted between the housing and the corrugated pipe and is rotatably connected to all the blades at the same time; the rack is inserted into the housing and extends along a direction parallel to the axis of the central cylinder and can slide along a direction parallel to the axis of the central cylinder; the collection chamber is arranged inside the housing; the collection housing is inserted into the housing and can rotate about a first axis perpendicular to the axis of the central cylinder. An opening and a ring gear are provided on the collection housing. The opening can communicate with the housing or the collection chamber. The axis of the ring gear coincides with the first axis; the third gear is inserted into the housing and can rotate about its own axis and meshes with the rack and the ring gear at the same time; the second elastic member is connected between the rotating ring and the rack.

[0022] Further, the impurity removal mechanism further includes two seals respectively disposed on both sides of the ring gear.

[0023] Further, the circulating water automatic treatment device further includes a differential multi-stage filter that communicates with the water outlet and is configured to perform multi-stage filtration on the circulating water.

[0024] Further, the differential multi-stage filter includes an outer box body and a plurality of filter cartridges. The plurality of filter cartridges are all inserted into the outer box body, sleeved with each other, and can all rotate around their own axes; the outer box body has a water inlet and a drain outlet, and the water inlet is simultaneously communicated with the water outlet and the outermost filter cartridge; the drain outlet is communicated with the innermost filter cartridge.

[0025] The beneficial effects of the present invention are as follows:

[0026] During the use of the circulating water automatic treatment equipment provided by the present invention, when the first filter holes are blocked, the sliding part is adjusted to move to the second position through the position adjustment mechanism, so that the sliding part forms a sliding fit with the spiral groove. Then, the corrugated pipe is driven to rotate around its own axis through the driving mechanism. When the corrugated pipe rotates, the base ring is synchronously driven to rotate. Under the cooperation of the sliding part and the spiral groove, the base ring simultaneously moves reciprocally along the axis direction of the central cylinder. On the one hand, it drives the blades to rotate and move reciprocally along the axis, so as to stir the circulating water in all directions, which is beneficial to improving the mixing uniformity of the circulating water and the flocculant, and further beneficial to improving the generation rate of flocs and the purification quality of the circulating water. On the other hand, it makes the two parts of the corrugated pipe connected to the base ring alternately stretch and compress, and the volumes of the two chambers alternately decrease and increase. When the corrugated pipe is compressed, the volume of the chamber inside it decreases and the pressure increases, so that the water can flow from the inside to the outside to backwash the first filter holes, thereby realizing self-cleaning. When the corrugated pipe is stretched, the volume of the chamber inside it increases and the pressure decreases, so that the water can more easily flow from the outside to the inside through the first filter holes, thereby improving the filtration efficiency.

[0027] Furthermore, by setting that the spiral groove has two symmetrically arranged spiral sub-grooves; each spiral sub-groove has two spiral sub-grooves with different pitches, and the spiral sub-groove with a smaller pitch in the same spiral sub-groove is located inside the spiral sub-groove with a larger pitch; when the sliding part moves in the spiral sub-groove with a smaller pitch, the water in the compressed corrugated pipe can pre-backwash the first filter holes. When the sliding part moves in the spiral sub-groove with a larger pitch, the water in the compressed corrugated pipe can not only perform secondary pressurized backwashing on the first filter holes, which is beneficial to improving the cleaning effect on the first filter holes, but also wash the impurities adhered to the outer peripheral wall of the corrugated pipe, reducing the influence of the impurities on the deformation of the corrugated pipe and the movement of the base ring while ensuring the cleanliness of the outer peripheral wall of the corrugated pipe.

[0028] Furthermore, by setting the impurity removal mechanism, during the use process, the flocs in the shell can be automatically cleaned, avoiding the risk of increasing the blockage of the first filter holes caused by the continuous accumulation of the flocs in the shell.

[0050] Such as Figures 1 to 8As shown in the figure, the circulating water automatic treatment equipment provided by the embodiment of the present invention is used for flocculation filtration treatment of circulating water, and is set to include a housing 1, a flocculant adder 2, a central cylinder 3, a corrugated pipe 4, a base ring 5, a driving mechanism and a position adjusting mechanism 7. The housing 1 has a water inlet 101 and a water outlet 102; the flocculant adder 2 is arranged on the housing 1 and configured to be able to add flocculant into the housing 1; the central cylinder 3 is inserted into the housing 1, and the central cylinder 3 is simultaneously communicated with the water inlet 101 and the water outlet 102. Two spiral grooves 301 are arranged on the central cylinder 3. The spiral directions of the two spiral grooves 301 are opposite, and the head and the tail are connected to form a closed movement path; the corrugated pipe 4 is inserted between the housing 1 and the central cylinder 3. The corrugated pipe 4 can rotate around its own axis and can also deform along its own axis direction. The two ends of the corrugated pipe 4 are respectively rotatably arranged on the housing 1 and the central cylinder 3. A first filter hole 401 is arranged on the corrugated pipe 4; the base ring 5 is inserted between the central cylinder 3 and the corrugated pipe 4 and is fixedly connected to the corrugated pipe 4. The base ring 5 divides the space between the central cylinder 3 and the corrugated pipe 4 into two chambers; a sliding part 501 is inserted on the inner peripheral wall of the base ring 5. The sliding part 501 can slide in the radial direction and has corresponding first and second positions before and after sliding. When in the first position, the sliding part 501 is disengaged from the spiral groove 301. When in the second position, the sliding part 501 forms a sliding fit with the spiral groove 301; a plurality of blades 502 are arranged on the outer peripheral wall of the base ring 5. The plurality of blades 502 are arranged circumferentially and are all located outside the corrugated pipe 4; the driving mechanism is configured to be able to provide a driving force for the rotation of the corrugated pipe 4; the position adjusting mechanism 7 is configured to be able to switch the position of the sliding part 501.

[0051] Specifically in this embodiment, the housing 1 is of a cylindrical structure and is vertically arranged during use; the water inlet 101 is opened on the circumferential side wall at the bottom of the housing 1, and the water outlet 102 is opened on the circumferential side wall at the top of the housing 1 and is arranged opposite to the water inlet 101 to ensure that the circulating water can form a stable upward and long flow path in the housing 1. During the flow of the circulating water, the flocs can settle to the bottom of the housing 1 more efficiently under the action of gravity, thereby facilitating the improvement of the separation degree of the circulating water and the flocs. The flocculant adder 2 is arranged at the water inlet 101. The flocculant adder 2 includes a main body and a switching valve. The main body is of a bottle-shaped structure. The main body is arranged on the housing 1 with the bottle mouth facing down during installation and is communicated with the water inlet 101. The main body is filled with flocculant during use; the switching valve is located at the bottle mouth of the main body during installation and has an open state and a closed state, so as to be able to change the on-off state between the main body and the water inlet 101.

[0052] The central cylinder 3 is vertically arranged during installation; for facilitating connection with the water inlet 101, two groups of water inlet holes 302 are provided on the circumferential side wall of the central cylinder 3. The two groups of water inlet holes 302 are arranged along the axial direction of the central cylinder 3. Each group includes multiple water inlet holes 302. The multiple water inlet holes 302 in the same group are evenly arranged circumferentially and are all connected to the water inlet 101. The two groups of water inlet holes 302 are located in the middle and lower parts of the central cylinder 3; for facilitating connection with the water outlet 102, a drain hole 303 is provided on the circumferential side wall at the top of the central cylinder 3. The central cylinder 3 is connected to the water outlet 102 through the drain hole 303; a partition ring 103 is coaxially arranged on the inner peripheral wall of the outer shell 1. The partition ring 103 is arranged close to the top of the outer shell 1. During installation, the partition ring 103 is sealingly sleeved on the central cylinder 3 and axially divides the interior of the outer shell 1 into two chambers. The upper chamber is connected to the drain hole 303, ensuring that the circulating water entering the upper chamber from the drain hole 303 cannot directly fall back into the lower chamber under the blockage of the partition ring 103, avoiding the situation of ineffective filtration; both spiral grooves 301 are arranged on the outer peripheral wall of the central cylinder 3, and one of the spiral grooves 301 extends in the clockwise direction, and the other spiral groove 301 extends in the counterclockwise direction. The two spiral grooves 301 are continuously and crosswise arranged along the axis direction of the central cylinder 3.

[0053] The corrugated pipe 4 is vertically arranged during installation; the top end of the corrugated pipe 4 is rotatably and hermetically arranged on the partition ring 103, and the bottom end is rotatably and hermetically arranged on the bottom end surface of the central cylinder 3; there are multiple groups of first filter holes 401. The multiple groups of first filter holes 401 are arranged at equal intervals along the axial direction of the corrugated pipe 4. Each group includes multiple first filter holes 401. The multiple first filter holes 401 in the same group are evenly arranged circumferentially and are all opened on the relatively concave circumferential side wall of the corrugated pipe 4. The outer peripheral wall of the base ring 5 penetrates through the corrugated pipe 4 along the circumferential direction from the inside to the outside, dividing the corrugated pipe 4 into upper and lower parts. The bottom end of the upper corrugated pipe 4 is fixedly arranged on the top end surface of the base ring 5, and the top end of the lower corrugated pipe 4 is fixedly arranged on the bottom end surface of the base ring 5, ensuring that the corrugated pipe 4 and the base ring 5 can rotate synchronously; for facilitating the installation of the sliding part 501, a first sliding groove 503 is provided on the inner peripheral wall of the base ring 5. The first sliding groove 503 extends along the radial direction of the base ring 5. During installation, the sliding part 501 is slidably inserted into the first sliding groove 503.

[0054] Optionally, the number of the blades 502 can be set to four and are evenly arranged circumferentially.

[0055] Optionally, the sliding part 501 can be set to have a structure similar to the slider that cooperates with the double - spiral screw and the double - spiral groove. A shuttle - shaped protrusion is provided on the slider. During installation, the shuttle - shaped protrusion is slidably inserted into the double - spiral groove, so as to be able to drive the slider to reciprocally slide along the axial direction of the double - spiral screw.

[0056] Initially, the sliding part 501 is in the first position. At this time, the sliding part 501 is disengaged from the spiral groove 301; the switching valve is in the closed state, and the main body is disconnected from the water inlet 101.

[0057] During use, first add circulating water into the housing 1 through the water inlet 101; at the same time, adjust the switching valve to the open state so that the main body is in communication with the water inlet 101, so that the flocculant inside the main body flows downward under the action of gravity and flows into the water inlet 101. Subsequently, it enters the housing 1 together with the circulating water driven by the circulating water; at the same time, the bellows 4 is driven to rotate by the driving mechanism. When the bellows 4 rotates, the blade 502 is driven to rotate by the base ring 5. When the blade 502 rotates, it can stir the circulating water and the flocculant in the housing 1, so as to promote the aggregation of the wastes in the circulating water to form flocs with larger particle sizes for filtration, improving the purification efficiency and effect of the circulating water; the circulating water and the flocs are then separated through the first filter holes 401. Among them, the circulating water enters the inside of the bellows 4, and then passes through the water inlet holes 302 and the drain holes 303 in sequence, and flows out from the water outlet 102; the flocs remain outside the bellows 4.

[0058] After operating for a period of time, the first filter holes 401 are blocked; first, the sliding part 501 is adjusted by the position adjusting mechanism 7 to move from the first position to the second position, so that the sliding part 501 forms a sliding fit with the spiral groove 301; the driving mechanism continues to work, driving the bellows 4 to rotate around its own axis. Due to the cooperation between the sliding part 501 and the spiral groove 301, the base ring 5 will not only rotate with the bellows 4, but also reciprocate along the axis of the central cylinder 3; this compound movement of the base ring 5 causes the blade 502 on its outer peripheral wall to reciprocate axially while rotating, stirring the circulating water in all directions. On the one hand, the compound movement of the blade 502 further improves the mixing uniformity of the circulating water and the flocculant, increases the generation rate of the flocs, and thus improves the purification quality of the circulating water.

[0059] On the other hand, when the base ring 5 moves upward from the bottom, the bellows 4 located above will be compressed, the volume of its internal chamber will decrease, and the pressure will increase. The circulating water inside the bellows 4 located above will flow from the inside to the outside under the action of the pressure difference, strongly backwashing the upper part of the first filter holes 401, washing away the impurities and flocs blocking the upper part of the first filter holes 401, and realizing the self-cleaning of the upper part of the first filter holes 401. The bellows 4 located below will stretch, the volume of its internal chamber will increase, and the pressure will decrease. The circulating water outside the bellows 4 located below is more likely to enter the bellows 4 through the first filter holes 401 under the action of the pressure difference, thereby effectively improving the filtration efficiency. Similarly, when the base ring 5 moves downward from the top, the bellows 4 located above will stretch, the volume of its internal chamber will increase, and the pressure will decrease. The circulating water outside the bellows 4 located above is more likely to enter the bellows 4 through the first filter holes 401 under the action of the pressure difference, thereby effectively improving the filtration efficiency. The bellows 4 located below will be compressed, the volume of its internal chamber will decrease, and the pressure will increase. The circulating water inside the bellows 4 located below will flow from the inside to the outside under the action of the pressure difference, strongly backwashing the lower part of the first filter holes 401, and washing away the impurities and flocs blocking the lower part of the first filter holes 401, realizing the self-cleaning of the lower part of the first filter holes 401.

[0060] After running for a period of time, the first filter holes 401 are unclogged. The sliding part 501 is adjusted by the positioning mechanism 7 to move from the second position to the first position, so that the sliding part 501 is disengaged from the spiral groove 301. At this time, all the first filter holes 401 are used for filtering the circulating water to ensure the filtration efficiency.

[0061] Furthermore, the central cylinder 3 can rotate around its own axis. The driving mechanism is set to include a driving member, a first gear 602, a second gear 603, and an internal gear ring 604. The driving member is configured to be able to provide the driving force for the rotation of the central cylinder 3. The first gear 602 is fixedly sleeved on the central cylinder 3. The second gear 603 is arranged on the outer shell 1 and can rotate around its own axis and meshes with the first gear 602. The internal gear ring 604 is arranged on the outer shell 1 and can rotate around its own axis and is fixedly connected to the bellows 4. The internal gear ring 604 meshes with the second gear 603.

[0062] Specifically in this embodiment, the driving member is set as the first driving motor 601. When the first driving motor 601 is installed, it is arranged on the top of the outer shell 1. The motor shaft of the first driving motor 601 is vertically downward and penetrates the top of the outer shell 1 and is coaxially and fixedly arranged on the top of the central cylinder 3 to ensure that it can both support the central cylinder 3 and drive the central cylinder 3 to rotate. The internal gear ring 604 is coaxially and rotatably arranged at the bottom of the partition ring 103. The top end of the bellows 4 is coaxially and fixedly arranged at the bottom of the internal gear ring 604 to ensure that the bellows 4 can follow the movement when the internal gear ring 604 rotates. The second gear 603 is rotatably arranged at the bottom of the partition ring 103.

[0063] During use, the first driving motor 601 is started. The first driving motor 601 drives the central cylinder 3 to rotate. The central cylinder 3 drives the first gear 602 to rotate. The first gear 602 drives the internal gear ring 604 to rotate through the second gear 603. The internal gear ring 604 drives the corrugated pipe 4 to rotate.

[0064] Furthermore, the sliding part 501 is made of a magnetic material; the positioning mechanism 7 is arranged to include a first elastic member and an electromagnet 702. The first elastic member is arranged between the base ring 5 and the sliding part 501. Under the action of the first elastic member, the sliding part 501 has a tendency to move inward; the electromagnet 702 is inserted into the base ring 5 and can form a magnetic connection with the sliding part 501 when energized and can drive the sliding part 501 to move outward.

[0065] Specifically in this embodiment, the first elastic member is arranged as a compression spring 701, and is inserted into the first sliding groove 503 and is arranged between the outer end of the first sliding groove 503 and the sliding part 501. Under the action of the compression spring 701, the sliding part 501 has a tendency to move inward; the electromagnet 702 is inserted into the sliding groove and is located at the outer end of the first sliding groove 503 to ensure that a magnetic connection can be formed with the sliding part 501 when energized and can drive the sliding part 501 to move outward.

[0066] Optionally, the sliding part 501 can be arranged to be made of magnetic materials such as iron, cobalt, and nickel.

[0067] Initially, the electromagnet 702 is energized so that a magnetic connection is formed between the electromagnet 702 and the sliding part 501. Then, under the action of the magnetic force, the sliding part 501 is driven to move outward along the first sliding groove 503 to move from the second position to the first position and remain in the first position. When the sliding part 501 moves, the compression spring 701 is synchronously compressed.

[0068] When the first filter hole 401 is blocked, the current flowing into the electromagnet 702 is disconnected. At this time, under the action of the compression spring 701, the sliding part 501 moves inward along the first sliding groove 503 to move from the second position to the first position and remain in the second position.

[0069] In some embodiments, it is arranged that the spiral groove 301 has two symmetrically arranged spiral sub-grooves 3011; each spiral sub-groove 3011 has two spiral sub-slots 30111 with different pitches, and the spiral sub-slot 30111 with a smaller pitch in the same spiral sub-groove 3011 is located inside the spiral sub-slot 30111 with a larger pitch.

[0070] Specifically in this embodiment, as Figure 5As shown, for the same spiral groove 301, from top to bottom, there are successively spiral sub-grooves 30111 with a larger pitch, spiral sub-grooves 30111 with a smaller pitch, spiral sub-grooves 30111 with a smaller pitch, and spiral sub-grooves 30111 with a larger pitch. And the two spiral sub-grooves 30111 with a larger pitch of the same spiral groove 301 are symmetrically arranged, and the two spiral sub-grooves 30111 with a smaller pitch of the same spiral groove 301 are symmetrically arranged.

[0071] During the use process, when the sliding part 501 moves in the spiral sub-groove 30111 with a smaller pitch, due to the smaller pitch, the moving speed of the base ring 5 in the axial direction of the central cylinder 3 is relatively slow. At this time, during the compression process of the bellows 4 connected thereto, the pressure change of the internal circulating water is relatively gentle, and the first filter holes 401 can be pre-backflushed. This pre-backflushing effect can initially remove some relatively loose impurities and flocs attached to the surface of the first filter holes 401, and prepare for the subsequent more thorough cleaning work.

[0072] When the sliding part 501 moves in the spiral sub-groove 30111 with a larger pitch, the situation is different. Due to the larger pitch, the moving speed of the base ring 5 along the axial direction of the central cylinder 3 is accelerated. This makes the pressure of the internal circulating water in the bellows 4 increase rapidly in a short time during the compression process. The water in the compressed bellows 4 can not only perform a secondary pressurized backflush on the first filter holes 401. Compared with the pre-backflushing, the intensity of this secondary pressurized backflush is greater, and it can effectively remove stubborn blockages deep in the first filter holes 401, thereby greatly improving the cleaning effect on the first filter holes 401.

[0073] At the same time, due to the larger pitch, for the compressed bellows 4, the outer side walls of the bellows 4 on both sides of the same group of the first filter holes 401 can approach each other relatively. At this time, the water jetting out at high speed can also strongly wash the impurities adhering to the outer peripheral wall of the bellows 4. Through this flushing effect, the hindrance of the impurities to the deformation of the bellows 4 is reduced, ensuring that the bellows 4 can stretch and compress flexibly according to the design requirements; and it also reduces the influence of the impurities on the movement of the base ring 5, ensuring that the base ring 5 can stably reciprocate along the axial direction of the central cylinder 3 under the cooperation of the sliding part 501 and the spiral groove 301, thereby ensuring the efficient and stable operation of the entire equipment and continuously providing a reliable filtering and self-cleaning function for the purification of the circulating water.

[0074] In some other embodiments, in the treatment process of the circulating water, the flocculant causes the waste in the circulating water to form flocs, and these flocs will gradually precipitate and accumulate in the housing 1 during the operation of the equipment; if not cleaned in time, over time, the stock of flocs in the housing 1 will continue to increase. On the one hand, a large amount of flocs will occupy the effective space in the housing 1, affecting the normal flow path and flow rate of the circulating water, thereby interfering with the full mixing of the circulating water and the flocculant and the subsequent filtration and separation process. On the other hand, and more critically, too many flocs will significantly increase the risk of clogging of the first filter hole 401. The flocs may approach the first filter hole 401 along with the flow of the circulating water and accumulate around the first filter hole 401, eventually causing the first filter hole 401 to be blocked, seriously affecting the filtration efficiency and operation stability of the equipment.

[0075] To solve this problem, the circulating water automatic treatment device is further provided with a debris removal mechanism 8, and the debris removal mechanism 8 is configured to be able to clean the flocs in the housing 1. In this way, by automatically cleaning the flocs through the debris removal mechanism 8, not only is the efficient treatment process of the circulating water in the housing 1 maintained, ensuring that the circulating water and the flocculant can be fully mixed to quickly form flocs, but also the possibility of the first filter hole 401 being blocked due to the accumulation of flocs is greatly reduced, providing a strong guarantee for the long-term stable and efficient operation of the equipment, enabling the circulating water automatic treatment device to continuously exert its excellent water resource recycling efficiency in actual application scenarios such as industrial production.

[0076] Furthermore, the debris removal mechanism 8 is provided to include a rotating ring 801, a rack 802, a collection chamber 803, a collection housing 804, a third gear 805 and a second elastic member. The rotating ring 801 is inserted between the housing 1 and the corrugated pipe 4 and is simultaneously rotatably connected to all the blades 502; the rack 802 is inserted inside the housing 1 and extends along the direction parallel to the axis of the central cylinder 3 and can slide along the direction parallel to the axis of the central cylinder 3; the collection chamber 803 is arranged inside the housing 1; the collection housing 804 is inserted inside the housing 1 and can rotate around a first axis, the first axis being perpendicular to the axis of the central cylinder 3. The collection housing 804 is provided with an opening 8041 and a ring gear 8042. The opening 8041 can communicate with the housing 1 or the collection chamber 803, and the axis of the ring gear 8042 coincides with the first axis; the third gear 805 is inserted inside the housing 1 and can rotate around its own axis and is simultaneously meshed with the rack 802 and the ring gear 8042; the second elastic member is connected between the rotating ring 801 and the rack 802.

[0077] Specifically in this embodiment, the rotating ring 801 rotates and sleeves on the bottoms of all the blades 502; the rack 802 is vertically arranged; to facilitate the installation of the rack 802, a second chute 104 is provided inside the bottom of the housing 1, and the second chute 104 extends in the vertical direction. When installed, the rack 802 is slidably inserted into the second chute 104; the collection chamber 803 is provided inside the bottom of the housing 1; the collection housing 804 can be set as a spherical structure; to facilitate the installation of the collection housing 804, an installation groove 105 is formed inside the bottom of the housing 1. The installation groove 105 is a spherical structure and is located above the collection chamber 803. The installation groove 105 is communicated with both the housing 1 and the collection chamber 803 at the same time. When installed, the collection housing 804 is rotatably inserted into the installation groove 105; an opening 8041 is formed on the spherical wall of the collection housing 804, and the shape is circular; two rotating rods 8043 are arranged on the outer spherical wall of the collection housing 804. The two rotating rods 8043 are symmetrically arranged with respect to the center of the sphere of the collection housing 804. The axis of the rotating rod 8043 is perpendicular to the axis of the housing 1 and coincides with the first axis. When installed, the two rotating rods 8043 are rotatably inserted into the spherical side wall of the installation groove 105; a ring gear 8042 is arranged on the outer spherical wall of the collection housing 804, and the axis of the ring gear 8042 coincides with the center of the sphere of the collection housing 804 and the axis of the rotating rod 8043. The ring gear 8042 coincides with the opening 8041, ensuring that when the collection housing 804 rotates, the opening 8041 can rotate synchronously to communicate with the housing 1 or the collection chamber 803; the third gear 805 is inserted into the bottom inside of the housing 1 and is located on the same side of the collection chamber 803 as the rack 802. The axis of the third gear 805 is perpendicular to the axis of the housing 1; the second elastic member is set as a rigid spring 806 to ensure that it is not easily twisted and bent.

[0078] Optionally, the collection housing 804 can also be set as a columnar structure and is horizontally inserted into the bottom inside of the housing 1. The axis of the collection housing 804 is perpendicular to the axis of the housing 1 and coincides with the first axis; the installation groove 105 is set as a columnar structure and is horizontally arranged; the opening 8041 is formed on the circumferential side wall of the collection housing 804; the ring gear 8042 is arranged on the outer peripheral wall of the collection housing 804; the two rotating rods 8043 are symmetrically arranged at both ends of the collection housing 804, and the axis of the rotating rod 8043 coincides with the axis of the collection housing 804.

[0079] The elastic coefficient of the rigid spring 806 is greater than a preset value, such that the force required to compress the rigid spring 806 is greater than the resistance that hinders the rotation of the collection housing 804. Consequently, during use, when the base ring 5 moves downward from top to bottom, before the rack 802 reaches the bottom of the second chute 104, the rigid spring 806 will not be compressed, enabling the base ring 5 to drive the rack 802 to move synchronously downward from top to bottom through the blade 502, the rotating ring 801, and the rigid spring 806 in sequence. The rack 802 drives the collection housing 804 to rotate through the third gear 805; when the rack 802 reaches the bottom of the second chute 104, the opening 8041 is arranged upward and communicates with the outer shell 1, facilitating the collection of the flocculent substances deposited at the bottom of the outer shell 1; as the base ring 5 continues to move, the rigid spring 806 is compressed, and the position of the rack 802 remains unchanged, ensuring that the opening 8041 is always arranged upward and guaranteeing sufficient collection time.

[0080] When the base ring 5 moves upward from bottom to top, before the rigid spring 806 is completely released, the base ring 5 releases the rigid spring 806 through the blade 502 and the rotating ring 801 in sequence; when the rigid spring 806 is completely released, as the base ring 5 continues to move, the base ring 5 drives the rack 802 to move synchronously upward from bottom to top through the blade 502, the rotating ring 801, and the rigid spring 806 in sequence. The rack 802 drives the collection housing 804 to rotate through the third gear 805, first disconnecting the communication between the opening 8041 and the outer shell 1 and then connecting it to the collection chamber 803, so as to pour the flocculent substances in the collection housing 804 into the collection chamber 803, thereby realizing the automatic cleaning of the flocculent substances in the outer shell 1.

[0081] Further, the impurity removal mechanism 8 is provided to further include two seals, which are respectively arranged on both sides of the ring gear 8042.

[0082] Specifically in this embodiment, when the collection housing 804 is arranged in a spherical structure or a columnar structure, the seal is arranged in an annular belt structure. This shape can well fit the outer shape of the collection housing 804. The seal realizes effective sealing of the gap between the collection housing 804 and the installation groove 105 by tightly sleeving on the collection housing 804, reducing the amount of circulating water in the outer shell 1 flowing directly into the collection chamber 803 through the gap between the installation groove 105 and the collection housing 804.

[0083] In some other embodiments, to improve the filtering effect of the circulating water, it is set that the circulating water automatic treatment device further includes a differential multi-stage filter 9. The differential multi-stage filter 9 is communicated with the water outlet 102 and is configured to be able to perform multi-stage filtering on the circulating water, thereby being able to further improve the filtering effect of the circulating water.

[0084] Further, the differential multi-stage filter 9 is configured to include an outer housing 901 and a plurality of filter cartridges 902. The plurality of filter cartridges 902 are all inserted into the outer housing 901, sleeved with each other, and can all rotate around their own axes. The outer housing 901 has a water inlet 9011 and a drain outlet 9012. The water inlet 9011 is simultaneously communicated with the water outlet 102 and the outermost filter cartridge 902. The drain outlet 9012 is communicated with the innermost filter cartridge 902.

[0085] Specifically in this embodiment, the outer housing 901 is horizontally arranged on the outer peripheral wall of the top of the outer shell 1. Taking the number of filter cartridges 902 being four as an example, as Figure 8 shown, the filter cartridges 902 are horizontally inserted into the outer housing 901. The four filter cartridges 902 are coaxially arranged. The left ends of the four filter cartridges 902 are all rotatably arranged on the left inner end surface of the outer housing 901, and the right ends are all suspended. The water inlet 9011 and the drain outlet 9012 are both opened on the left end surface of the outer housing 901, and the drain outlet 9012 is located in the middle to ensure communication with the innermost filter cartridge 902. The water inlet 9011 is located at the lower part to ensure communication with the outermost filter cartridge 902. Each filter cartridge 902 is provided with a second filter hole, and the second filter hole communicates the water inlet 9011 and the drain outlet 9012 to ensure filtration of the circulating water.

[0086] To facilitate providing the driving force for the rotation of the filter cartridge 902, the differential multi-stage filter 9 is further configured to include a rotating column 903, three rotating sleeves 904, two first bevel gears 905, two second bevel gears 906, a third bevel gear 907, a fourth bevel gear 908, a mounting plate 9013 and a second driving motor 909, as Figure 8As shown in the figure, the left end of the rotating column 903 is vertically and coaxially arranged on the right end face of the innermost filter cartridge 902, and the right end of the rotating column 903 penetrates through the right end face of the outer casing 901 and is suspended; the three rotating sleeves 904 are sleeved with each other. Taking the outermost rotating sleeve 904 as an example, the left end of this rotating sleeve 904 is vertically and coaxially arranged on the right end face of the outermost filter cartridge 902, and the right end penetrates through the right end face of the outer casing 901 and is suspended; the two second bevel gears 906 are respectively fixedly sleeved on the right ends of the rotating column 903 and the outermost rotating sleeve 904; the two first bevel gears 905 are respectively fixedly sleeved on the right ends of the other two rotating sleeves 904 and are located between the two second bevel gears 906 to avoid interference; the mounting plate 9013 is vertically arranged on the right end face of the outer casing 901, and the plate surface of the mounting plate 9013 is horizontally arranged; the second driving motor 909 is arranged on the top of the mounting plate 9013, and the motor shaft of the second driving motor 909 is vertically upward; the fourth bevel gear 908 is fixedly sleeved on the motor shaft of the second driving motor 909 and meshes with the two second bevel gears 906 at the same time; the third bevel gear 907 is coaxially and fixedly arranged on the top of the fourth bevel gear 908 and meshes with the two first bevel gears 905 at the same time.

[0087] During the use process, the second driving motor 909 is started, and the second driving motor 909 drives the third bevel gear 907 and the fourth bevel gear 908 to rotate at the same time. Among them, the third bevel gear 907 drives the two filter cartridges 902 in the middle to rotate in the opposite direction through the meshing with the first bevel gear 905, and the fourth bevel gear 908 drives the two filter cartridges 902 at the innermost and outermost to rotate in the opposite direction through the meshing with the second bevel gear 906. And the module of the second bevel gear 906 is greater than the module of the first bevel gear 905, and the module of the fourth bevel gear 908 is greater than the module of the third bevel gear 907, so that the outermost filter cartridge 902 and the adjacent filter cartridge 902 have the same rotation direction but different rotation speeds, the two filter cartridges 902 in the middle have the same rotation speed but different rotation directions, so that the innermost filter cartridge 902 and the adjacent filter cartridge 902 have the same rotation direction but different rotation speeds. Furthermore, when the circulating water entering from the water inlet 9011 passes through the four filter cartridges 902 from the outside to the inside in turn, it can be in a strong turbulent flow state. The circulating water flows between the filter cartridges 902 with different rotation speeds and different rotation directions, constantly changing the flow direction and flow rate, increasing the collision probability between the impurities in the circulating water and the wall of the filter cartridge 902, so that the impurities can be intercepted more fully, thus significantly improving the filtering effect of the circulating water.

[0088] The filtered circulating water is then discharged through the drain port 9012.
