Description

Technical Field

[0001] This invention relates to the field of washing machine technology, and in particular to a high-efficiency multi-layer washing machine. Background Technology

[0002] The washing machine mainly consists of two parts: a cylindrical washing tank and a rake scraper. It is generally used for the concentration and purification of solid mineral slurries in industries such as coal, chemical, building materials, water source and sewage treatment.

[0003] Washing machines are typically cylindrical at the top and conical at the bottom, with a bridge frame mounted on top. The transmission mechanism is located on the bridge frame and connected to the transmission mechanism via a drive shaft. The bottom of the drive shaft is connected to a rake frame, and the slurry is swirled into the washing tank.

[0004] Commonly used washing machines can treat mineral slurry and wastewater by sedimentation. However, single-layer washing and sedimentation systems have limited processing capacity, and the slurry or detergent can cause surface fluctuations and turbidity when flushed into the washing tank, reducing washing quality. Sometimes, the size of the washing tank is increased to improve washing efficiency. However, increasing the size of the washing tank also increases the floor space of the washing machine and the radius of rotation, leading to higher maintenance costs. Therefore, a washing machine with multi-layer washing function is needed. The length of the rotating shaft of a multi-layer washing machine with central shaft drive is inevitably longer than that of a single-layer washing machine. The longer the rotating shaft, the lower the stability. Therefore, adopting a multi-layer structure washing machine that can increase washing efficiency requires effective measures to maintain the overall stability of the system. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency multi-layer washing machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high-efficiency multi-layer washing machine includes a multi-layer pool and a base.

[0010] Preferably, a cross-shaped fixing frame is provided at the top of the inside of the current stabilizer box, and a central shaft is movably connected to the center of the cross-shaped fixing frame. Several evenly distributed grid plates are fixedly connected between the bottom end of the cross-shaped fixing frame and the bottom end face of the current stabilizer box, and each grid plate is inclined.

[0011] Preferably, a bracket is fixedly provided at the end of the first feed pipe and the connection section of the flow stabilizer box. A fan blade is connected to the central shaft of the bracket. A universal joint is provided at the end of the fan blade connecting shaft. The bottom shaft of the other side of the universal joint is connected to the bottom of the flow stabilizer box. A mixing blade is fixedly provided on the shaft between the bottom of the flow stabilizer box and the universal joint.

[0012] Preferably, the stirring mechanism includes a stirring shaft, a stirring rod, and a stirring tank. The stirring tank has a conical structure and is fixedly connected to the bottom of the third tank. The stirring shaft has a hollow cylindrical structure, with the top end of the stirring shaft fixedly connected to the bottom end of the central shaft, and a stirring rod fixedly connected to the outer wall of the stirring shaft.

[0013] Preferably, the anti-deviation mechanism includes a fixed base, sensor balls, and an electric adjusting rod. The fixed base is fixedly connected to the bottom of the mixing tank. The outer diameter of the fixed base is smaller than the inner diameter of the mixing shaft. The upper part of the fixed base is placed in the hollow part inside the mixing shaft. Several sensor balls are evenly arranged at the connection between the fixed base and the mixing shaft. A fixed frame is fixedly installed on the upper part of the mixing tank. The center of the fixed frame has a ring that fits on the mixing shaft. Each bracket of the fixed frame is provided with an electric adjusting rod with an arc-shaped bend on the side near the mixing shaft.

[0014] Preferably, the scraper mechanism includes a scraper, an arc-shaped sleeve, and a motor. The arc-shaped sleeves are staggered and fixed on both sides of the bottom end of the rake frame. T-shaped movable blocks adapted to the arc-shaped sleeves are provided inside the arc-shaped sleeves. The scraper is fixedly connected to the ends of every two T-shaped movable blocks. The central shaft at the top of the scraper is connected to the motor fixedly installed at the bottom end of the rake frame. A pressure sensor is provided inside the scraper at the end of each rake frame. The pressure sensor is electrically connected to an external controller.

[0015] Preferably, the scraper has a trapezoidal structure that is larger at the top and smaller at the bottom, and the inclined surface of the scraper is a curved surface. Several rakes are evenly and obliquely arranged on the curved surface of the scraper, and the ends of the rakes are fixedly connected to the curved surface of the scraper by a connecting rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This invention features a multi-layered washing machine with three layers, which provides a larger volume compared to commonly used single-layer washing machines without requiring additional floor space. This increases the washing machine's processing capacity. The first, second, and third layers are interconnected by a collection box, facilitating the transfer of sediment scraped from the upper layers into the lower layers for final discharge.

[0018] This invention utilizes a flow stabilizing box. The first tank is exposed to the elements and filled with liquid. During continuous feeding, the flow stabilizing box reduces the impact of new material entering multiple tanks, preventing the direct overflow of unwashed slurry. The inclined and fixed grid plates in the flow stabilizing box effectively slow down the incoming slurry and detergent, reducing impact. To cooperate with the flow stabilizing box, the slurry and detergent are buffered and slowed down by the fan blades as they flow through it. After being buffered and slowed down by the fan blades and grid plates, the flow velocity of the mixed liquid is reduced. Under the rotation of the mixing blades, a small amount of sediment can be effectively moved, preventing sedimentation. The four areas in the flow stabilizing box are arranged opposite each other, with two feeding points and two buffering and slowing points. When used in conjunction, the flow velocity of the mixed liquid entering the first tank is uniform, less prone to foaming, and reduces overflow and mixing.

[0019] This invention incorporates a scraper mechanism and an anti-deviation mechanism. These two mechanisms work together. When the detection system detects uneven force on the rake frame causing a shift in the central axis, the anti-deviation mechanism controls the electric adjusting rod to engage with the central axis, limiting its position. Meanwhile, the scraper mechanism, experiencing greater resistance, uses the rake to quickly break up sediment blocks while simultaneously adjusting the scraper angle via a controller-activated motor. This reduces the relative contact area between the scraper and the sediment, thereby lowering the resistance on the rake frame. Once the sediment is scraped into the center of the multi-layer tank, the resistance decreases to within the normal operating range, and the scraper and electric adjusting rod are then returned to their initial positions. This reduces the risk of damage to the rake frame and central axis. Attached Figure Description

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0031] Reference Figure 1-9A high-efficiency multi-layer washing machine includes a multi-layer pool body 1 and a base 11. The multi-layer pool body 1 is set on the base 11. A ladder and walkway are set on the outer ring of the multi-layer pool body 1. The multi-layer pool body 1 is formed by connecting a first pool body 101, a second pool body 102 and a third pool body 103 vertically. A bridge frame 3 is set at the top of the first pool body 101. Two drive motors 2 are set in the middle of the bridge frame 3. The two drive motors 2 are geared to a central shaft 201. The central shaft 201 passes through the center of the multi-layer pool body 1. A flow stabilizing box 4 is movably connected to the top of the central shaft 201 and is set below the bridge frame 3. The bottom of the flow stabilizing box 4 is symmetrically provided with a discharge port. A stirring mechanism 9 and an anti-deviation mechanism 10 are set at the bottom of the central shaft 201. A rake frame 6 is fixedly connected to the central shaft 201 in the multi-layer pool body 1. Several scraping mechanisms 7 are evenly arranged at the bottom of the rake frame 6. The multi-layer washing machine features three tanks, offering a larger capacity compared to commonly used single-layer washing machines, without requiring additional floor space, thus increasing the washing machine's processing capacity. The first tank 101, second tank 102, and third tank 103 are interconnected by a receiving box, facilitating the transfer of sludge scraped from the upper tanks into the lower tanks. Finally, the sludge enters the mixing mechanism 9 and is extracted by the sludge pump. Two drive motors 2 work together to rotate the central shaft 201, which in turn drives the rake frame 6 fixed to it in a circular motion. The scraping mechanism 7 at the bottom of the rake frame 6 scrapes the sludge from the bottom of the multi-layer tank 1 into the multi-layer... At the center of pool 1, the slurry fed into the multi-layer pool 1 enters the flow stabilizing box 4 through the distribution box 8. In the flow stabilizing box 4, it mixes and flows into the first pool 101. As the processing capacity of the multi-layer pool 1 increases, the length of the central shaft 201 also increases. The amount of slurry deposited in each layer of the pool is not exactly the same, and the amount of mud deposited at the bottom is more or less. During the rotation and scraping of mud by each rake frame 6, uneven force will occur. In severe cases, the central shaft 201 will be deviated, affecting the normal operation of each rake frame 6 in the multi-layer pool 1. The top shaft of the central shaft 201 is connected between two drive motors 2, and the bottom end needs to use an anti-deviation mechanism 10 to balance the force on the rake frame 6.

[0032] As a technical optimization of the present invention, the bottom of the multi-layer tank 1 is a conical structure. A first distribution box 405 is fixedly installed at the bottom of the first tank 101, and a second distribution box 406 is fixedly installed at the bottom of the second tank 102. An overflow weir is provided at the top of the first tank 101, and overflow ports are provided at the top of the second tank 102 and the third tank 103. In order to facilitate the quick and effective scraping of the sediment, the bottom inclination angle of the multi-layer tank 1 is set between eight and fifteen degrees. At this time, the resistance of the scraper 701 is small, which can improve the scraping efficiency. The slurry and washing agent in the multi-layer tank 1 react, the sediment settles under the action of gravity, and the washed clear liquid is in the upper layer and is discharged through the top overflow port.

[0033] As a technical optimization of the present invention, a distribution box 8 is symmetrically arranged on the top two side walls of the first pool body 101. A first feed pipe 5, a second feed pipe 501 and a third feed pipe 502 are connected to the bottom of the distribution box 8. The end of the first feed pipe 5 is connected to the bottom of the flow stabilizing box 4. The end of the second feed pipe 501 is connected to the bottom of the first distribution box 405. The end of the third feed pipe 502 is connected to the bottom of the second distribution box 406. A first overflow pipe 12 and a second overflow pipe 13 are connected to the bottom of the distribution box 8. The end of the first overflow pipe 12 is connected to the overflow port of the second pool body 102, and the end of the second overflow pipe 13 is connected to the overflow port of the third pool body 103. Two distribution boxes 8 store the slurry and detergent to be cleaned, respectively. The slurry and detergent enter the flow stabilizing box 4 through the first feed pipe 5, enter the first distribution box 405 through the second feed pipe 501, and enter the second distribution box 406 through the third feed pipe 502. After the slurry and detergent are mixed in the distribution boxes, they flow into the multi-layer tank 1 for washing and stratification. The clear liquid after stratification overflows from the overflow port at the top of the multi-layer tank 1 to the first overflow pipe 12 and the second overflow pipe 13, so that the clear liquid returns to the distribution box 8 and is distributed to the overflow weir on the outer ring of the first tank 101 by the distribution box 8.

[0034] As a technical optimization of the present invention, a cross-shaped fixing frame is provided at the top of the inside of the flow stabilizer 4. The center of the cross-shaped fixing frame is movably connected to the central shaft 201. Several evenly distributed grid plates 404 are fixedly connected between the bottom end of the cross-shaped fixing frame and the bottom end face of the flow stabilizer 4. Each grid plate 404 is inclined. Because the multi-layer washing machine is in a continuous working state, the first pool 101 is exposed to the open air and the liquid in the pool is overflowing. In order to reduce the direct overflow of unwashed slurry caused by the impact of new material entering the multi-layer pool 1, a flow stabilizer 4 is set in the first pool 101. The inclined grid plates 404 fixed in the flow stabilizer 4 can effectively slow down the incoming slurry and detergent, reduce the impact. The cross-shaped arrangement divides the flow stabilizer 4 into four areas with different functions that cooperate with each other.

[0035] As a technical optimization of the present invention, a bracket is fixedly installed at the connection section between the end of the first feed pipe 5 and the flow stabilizer 4. A fan blade 401 is connected to the central shaft of the bracket, and a universal joint 402 is installed at the end of the connecting shaft of the fan blade 401. The bottom shaft of the other side of the universal joint 402 is connected to the bottom of the flow stabilizer 4. A mixing blade 403 is fixedly installed on the rotating shaft between the bottom of the flow stabilizer 4 and the universal joint 402. Because the distribution box 8 continuously feeds, a fan blade 401 is installed at the end of the first feed pipe 5 to cooperate with the operation of the flow stabilizer 4. When the slurry and detergent flow through the fan blade 401, they are buffered and slowed down by the fan blade 401. The fan blade 401 is connected to the bracket, and the impact force of the slurry and detergent will drive the fan blade 401 to rotate. The universal joint 402 connected to the fan blade 401 shaft is driven, which can drive the mixing blade 403 fixed on the rotating shaft to rotate. The slurry and detergent in the flow stabilizer 4 are also in a mixed state, and after passing through the fan blade 401 and the grid, they are further mixed. After the buffer deceleration of the grid plate 404, the flow rate of the mixed liquid is reduced. At this time, under the action of the detergent, some of the slurry in the stabilizing tank 4 will also be deposited. After a period of time, the stabilizing tank 4 is prone to accumulating sediment. Therefore, under the rotation of the mixing blade 403, a small amount of sediment can be effectively driven to prevent sediment from settling. The four areas in the stabilizing tank 4 are set up relative to each other, with two feeding points and two buffer deceleration points. When used in combination, the flow rate of the mixed liquid entering the first pool 101 is uniform, it is not easy to foam, and the overflow and mixing of water are reduced.

[0036] As a technical optimization of the present invention, the stirring mechanism 9 includes a stirring shaft 901, a stirring rod 902 and a stirring tank 903. The stirring tank 903 has a conical structure and is fixedly connected to the bottom of the third tank body 103. The stirring shaft 901 has a hollow cylindrical structure. The top end of the stirring shaft 901 is fixedly connected to the bottom end of the central shaft 201, and the stirring rod 902 is fixedly connected to the outer wall of the stirring shaft 901. After a period of washing, the suspended impurities in the slurry react with the detergent to form sediment. The sediment then enters the third tank 103 through the receiving boxes at the bottom of the first tank 101 and the second tank 102. Finally, it settles to the bottom of the third tank 103 and is scraped into the mixing tank 903 by the scraper 701. The sediment has a high density and does not flow out naturally, so it needs to be pumped out using a mud pump. When the mud pump is working, in order to prevent the sediment in the mixing tank 903 from being squeezed into clumps under the pressure of gravity and clogging the mixing tank 903, thus affecting the normal discharge of the sediment, it is necessary to continuously agitate the sediment in the mixing tank 903. The agitator shaft 901 is directly fixedly connected to the central shaft 201, so there is no need to use a separate motor to control the operation of the agitator shaft 901. The agitator shaft 901 and the central shaft 201 rotate synchronously, and the agitator rod 902, which is fixedly connected to the outer wall of the agitator shaft 901, can continuously agitate the sediment. At the same time, the mud pump at the bottom pumps out the sediment, so that the sediment cannot clog the mixing tank 903.

[0037] As a technical optimization of the present invention, the anti-deviation mechanism 10 includes a fixed base 111, a sensing ball 112, and an electric adjusting rod 113. The fixed base 111 is fixedly connected to the bottom of the stirring tank 903. The outer diameter of the fixed base 111 is smaller than the inner diameter of the stirring shaft 901. The upper part of the fixed base 111 is placed in the hollow part inside the stirring shaft 901. A plurality of sensing balls 112 are evenly arranged on the connection part between the fixed base 111 and the stirring shaft 901. A fixed frame 114 is fixedly installed on the upper part of the stirring tank 903. The center of the fixed frame 114 has a ring that is sleeved on the stirring shaft 901. Each bracket of the fixed frame 114 is provided with an electric adjusting rod 113 with an arc-shaped bend on the side near the stirring shaft 901. The upper part of the fixed seat 111 is sleeved on the hollow part at the bottom of the stirring shaft 901. The bottom of the fixed seat 111 is fixedly connected to the bottom of the stirring tank 903. When the central shaft 201 is offset, the pressure on the sensing ball 112 in contact with the inner wall of the stirring shaft 901 changes. When the pressure difference between the sensing balls 112 at relative positions is greater than the preset critical pressure difference of 0.2 MPa, the pressure sensor built into the sensing ball 112 sends a signal to the external controller. The external controller controls the electric adjusting rod 113 to extend. The arc-shaped bend at the front of the electric adjusting rod 113 abuts against the outer wall of the stirring shaft 901 to counteract the offset of the central shaft 201 caused by the uneven force on the rake 6. The fixed seat 111 itself can also play a role in limiting and assisting in preventing deviation.

[0038] As a technical optimization of the present invention, the scraper mechanism 7 includes a scraper 701, an arc-shaped sleeve 702, and a motor 704. The arc-shaped sleeves 702 are staggered and fixed on both sides of the bottom end of the rake frame 6. T-shaped movable blocks adapted to the arc-shaped sleeves 702 are provided inside the arc-shaped sleeves 702. The scraper 701 is fixedly connected to the ends of every two T-shaped movable blocks. The central shaft of the top end of the scraper 701 is connected to the motor 704 fixedly installed at the bottom end of the rake frame 6. A pressure sensor is provided inside the scraper 701 at the end of each rake frame 6. The pressure sensor is electrically connected to an external controller. Due to varying degrees of sediment accumulation generated by the reaction of slurry and detergent, the sediment at the bottom of the multi-layered tank 1 causes different levels of resistance to the scraper 701 during scraping. The scraper 701 at locations with higher sediment content experiences increased resistance, while the corresponding scraper 701 on the other side experiences unchanged force, resulting in uneven stress on the rake frame 6. The scraper 701 shaft is connected to the motor 704, and the T-shaped movable block can move within the arc-shaped sleeve 702. As the rake frame 6 rotates with the central shaft 201, when the pressure sensor inside the scraper 701 at the end of the rake frame 6 detects that the working resistance on one side of the rake frame 6 exceeds 4 MPa, it sends a signal to the external controller. The external controller then starts the motor 704 on the scraper 701 at the bottom of the current rake frame 6. The motor 704 outputs... When the shaft rotates counterclockwise, the T-shaped movable block slides outward along the arc-shaped sleeve 702, and the scraper 701 rotates counterclockwise around the shaft. The rotation direction of the scraper 701 is the same as the rotation direction of the rake frame 6, that is, the angle between the rotation direction of the scraper 701 and the rake frame 6 decreases, the relative contact area between the scraper 701 and the sediment decreases accordingly, and the resistance it receives also decreases, which helps to improve the overall balance of the rake frame 6. After scraping off the inner ring sediment, the outer ring sediment slides towards the center of the multi-layer tank 1, and the imbalance of forces is alleviated. When the resistance drops below 3.6 MPa, the external controller controls the motor 704 to rotate clockwise, and the scraper 701 returns to its initial position. Multiple sets of scrapers 701 work together and adjust to each other during the washing process. With the help of the anti-deviation mechanism 10, the stability of the system can be maintained.

[0039] As a technical optimization of the present invention, the scraper 701 has a trapezoidal structure that is larger at the top and smaller at the bottom, and the inclined surface of the scraper 701 is a curved surface. Several rakes 14 are evenly and obliquely arranged on the curved surface of the scraper 701, and the ends of the rakes 14 are fixedly connected to the curved surface of the scraper 701 by connecting rods. The curved surface shape that is larger at the top and smaller at the bottom can increase the contact area when the scraper 701 scrapes mud, thereby increasing the amount of mud scraped by each scraper 701 and improving work efficiency. The rakes 14 can assist the scraper 701 in quickly breaking up some of the compacted sediment, reducing the possibility of system shutdown caused by overloading of the rake frame 6.

[0040] In use, this invention first adds slurry and detergent to two distribution boxes 8 respectively. The slurry and detergent enter the flow stabilizing box 4, the first distribution box 405, and the second distribution box 406 through the first feed pipe 5, the second feed pipe 501, and the third feed pipe 502 respectively for initial mixing. The mixture then flows into the first pool 101, the second pool 102, and the third pool 103 respectively. Inside the multi-layer pool 1, the detergent and slurry are fully mixed over time. During the reaction stage, two drives are turned on. Motor 2, with its central shaft 201 connected to the drive motor 2 gear, begins to rotate. The rake frame 6, located in the multi-layer tank 1, rotates with the central shaft 201, driving the scraping mechanism 7. As the reaction proceeds, impurities in the slurry combine with the washing agent to form water-insoluble sediment. This sediment settles in the multi-layer tank 1 under gravity, eventually accumulating at the bottom. The clear slurry separates from the bottom sediment, residing at the top of each tank layer. The flow stabilizer 4 and the first dividing... Feed is continuously fed into the material bin 405 and the second distribution bin 406. The upper layer of clear liquid in the multi-layer tank 1 overflows, and the clear liquid in the third tank 103 and the second tank 102 overflows from the overflow port into the second overflow pipe 13 and the first overflow pipe 12, returning to the distribution box 8. In the distribution box 8, it is distributed to the overflow weir on the outer ring of the first tank 101, while the clear liquid in the first tank 101 overflows directly into the overflow weir. When the scraper mechanism 7 is working, the scraper 701 scrapes the sediment at the bottom of the multi-layer tank 1 into the multi-layer tank. In the central part, the sediment enters the receiving boxes of each layer in sequence and is finally collected in the mixing tank 903. The mixing rod 902 rotates continuously with the central shaft 201, and the sediment will not clog. Finally, it is discharged from the multi-layer tank 1 by the mud pump. When the rake frame 6 is rotating, the plow 14 set on the curved surface of the scraper 701 can effectively break the clumps of sediment. The scraper 701, which can move according to the resistance, is used in conjunction with the anti-deviation mechanism 10 to maintain the stability of the central shaft 201 when the rake frame 6 is subjected to uneven force.
