Description

Technical Field

[0001] This utility model relates to the technical field of vibrating screen devices, and in particular to an automatic cleaning structure for a multi-layer vibrating screen. Background Technology

[0002] As a key piece of equipment in the industrial screening field, the vibrating screen uses a vibrating motor as its core power source. Unbalanced weights are carefully fitted at the upper and lower ends of the motor's shaft. When the motor is running, the unique arrangement of these weights breaks the equilibrium state, generating continuous vibration. This vibration is efficiently transmitted to the screen mesh via a powerful spring and the vibrating body. Notably, by cleverly changing the phase angle of the upper and lower weights of the vibrating motor, the movement trajectory of the material on the screen surface can be flexibly controlled, precisely achieving the screening of materials of different specifications.

[0003] However, most vibrating screens at present do not have self-cleaning function. Once the inside of the equipment cylinder is contaminated with material residue and impurities, the cleaning operation is extremely difficult due to its structural limitations, narrow space and complex structure. It is not only time-consuming and labor-intensive, but also easily affects the subsequent screening accuracy and service life of the equipment due to untimely or incomplete cleaning. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an automatic cleaning structure for a multi-layer vibrating screen, aiming to improve the problem that most vibrating screens in the prior art lack self-cleaning function, and that after material residue and impurities accumulate inside the cylinder, cleaning is difficult, time-consuming and labor-intensive due to structural limitations, narrow space and complex construction. Furthermore, untimely or incomplete cleaning will affect the subsequent screening accuracy and service life.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an automatic cleaning structure for a multi-layer vibrating screen, comprising a cylinder, a connecting cover fixedly connected to the bottom of the cylinder, a machine base fixedly connected to the bottom of the connecting cover, adjustable support legs provided at the bottom of the machine base, a cleaning mechanism provided inside the cylinder, a discharge pipe provided outside the cylinder, and a screen provided inside the cylinder.

[0006] The cleaning mechanism includes a water storage tank located inside the base. A water pump is fixedly connected to the outside of the cylinder. The input end of the water pump is located inside the water storage tank via a connecting pipe. The output end of the water pump is fixedly connected to a water delivery pipe. A water delivery ring is fixedly connected to the end of the water delivery pipe away from the water pump. The outside of the water delivery ring is fixedly connected to the outside of the cylinder. Spray nozzles are fixedly connected to the outside of the water delivery ring. A circulation assembly is installed inside the cylinder.

[0007] Furthermore, the circulation assembly includes a return pipe, which is fixedly connected to the outside of the cylinder. A filter box is fixedly connected to the bottom end of the return pipe, and a conveying pipe is fixedly connected inside the filter box. The end of the conveying pipe away from the filter box is located inside the water storage tank.

[0008] Furthermore, each of the cylinders is fixedly connected to a spring at its bottom, and a base is fixedly connected to the end of the spring away from the cylinder. Each base is fixedly connected to a female seat, and an adjusting bolt is threaded into the interior of each female seat.

[0009] Furthermore, the end of the adjusting bolt away from the base abuts against the bottom of the cylinder, and all adjusting bolts are threaded inside the edge of the base.

[0010] Furthermore, the filter box is fixedly connected to the outside of the cylinder, and a filter screen is provided inside the filter box.

[0011] Furthermore, a drain pipe is fixedly connected inside the base, with one end of the drain pipe near the water storage tank located inside the water storage tank.

[0012] Furthermore, a mounting plate is fixedly connected inside the base, and a motor is fixedly connected inside the mounting plate.

[0013] Furthermore, both ends of the motor are fixedly connected with weights.

[0014] This utility model has the following beneficial effects:

[0015] In this invention, a water pump is used to extract water from the storage tank and transport it through a water delivery pipe. The water is then sprayed out through a nozzle on the water delivery ring to rinse the inside of the cylinder, making cleaning convenient. At the same time, the wastewater after rinsing flows into the filter box through a return pipe for filtration. The filtered water then flows into the storage tank through a delivery pipe, realizing water recycling and saving a large amount of water resources.

[0016] In this invention, multiple female seats are installed at the top edge of the base, and adjusting bolts are installed in the female seats. The vibration intensity can be adjusted by adjusting the distance between the bolts and the cylinder. In addition, multi-level adjustment can be achieved in conjunction with the motor. The cylinder can also be lifted by the limiting bolts to prevent the device from jumping during transportation. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Reference Figure 1 , Figure 2 Figure 3 An embodiment of this utility model is provided: an automatic cleaning structure for a multi-layer vibrating screen, including a cylinder 1, a connecting cover 19 fixedly connected to the bottom of the cylinder 1, a machine base 2 fixedly connected to the bottom of the connecting cover 19, adjustable support legs 3 provided at the bottom of the machine base 2, a cleaning mechanism provided inside the cylinder 1, a discharge pipe 20 provided outside the cylinder 1, and a screen 7 provided inside the cylinder 1.

[0024] The cleaning mechanism includes a water storage tank 8, which is located inside the base 2. A water pump 9 is fixedly connected to the outside of the cylinder 1. The input end of the water pump 9 is located inside the water storage tank 8 via a connecting pipe. The output end of the water pump 9 is fixedly connected to a water delivery pipe 10. A water delivery ring 11 is fixedly connected to the end of the water delivery pipe 10 away from the water pump 9. The outside of the water delivery ring 11 is fixedly connected to the outside of the cylinder 1. Spray nozzles 12 are fixedly connected to the outside of the water delivery ring 11. A circulation assembly is installed inside the cylinder 1, which includes a return flow mechanism. Pipe 13 and return pipe 13 are fixedly connected to the outside of cylinder 1. The bottom end of return pipe 13 is fixedly connected to filter box 14. Inside filter box 14, conveying pipe 16 is fixedly connected. The end of conveying pipe 16 away from filter box 14 is located inside water storage tank 8. The outside of filter box 14 is fixedly connected to the outside of cylinder 1. Filter screens 15 are installed inside filter box 14. Drain pipe 17 is fixedly connected to the inside of base 2. The end of drain pipe 17 near water storage tank 8 is located inside water storage tank 8.

[0025] After the cleaning program is started, the water pump 9 outside the cylinder 1 draws cleaning water (which can be clean water or prepared cleaning solution) from the water storage tank 8 inside the base 2 through the input end connection pipe. With the help of power, the water is sent to the water supply ring 11 through the water supply pipe 10. The water supply ring 11 diverts and evenly distributes the water flow to the nozzle 12. The nozzle 12 sprays water or cleaning solution onto the screen 7 and cylinder wall inside the cylinder 1 according to the preset angle and pressure, dispersing residual material particles and impurities on the screen 7, washing away dirt inside the cylinder 1, causing it to detach and converge to the bottom of the cylinder 1. The wastewater enters the filter box 14 through the bottom flow channel and return pipe 13. The filter screen 15 intercepts solid impurities and material residues according to the mesh size. The purified water returns to the water storage tank 8 through the delivery pipe 16, realizing water recycling. The water inside the water storage tank 8 is discharged through the drain pipe 17.

[0026] Reference Figure 1 , Figure 2 and Figure 3 Springs 6 are fixedly connected to the bottom of the cylinder 1. The end of the spring 6 away from the cylinder 1 is fixedly connected to the base 2. The top of the base 2 is fixedly connected to the female seat 4. The inside of the female seat 4 is threaded with adjusting bolts 5. The end of the adjusting bolt 5 away from the base 2 abuts against the bottom of the cylinder 1. The adjusting bolts 5 are threaded inside the edge of the base 2. The inside of the base 2 is fixedly connected to the mounting plate 21. The inside of the mounting plate 21 is fixedly connected to the motor 18. The two ends of the motor 18 are fixedly connected to the counterweights 22.

[0027] The top edge of the base 2 is equipped with a combination structure of a female seat 4 and an adjusting bolt 5. During operation, rotating the adjusting bolt 5 changes the degree of contact with the bottom of the cylinder 1, adjusts the compression state of the spring 6, and works with the motor 18 and the counterweights 22 at both ends to flexibly adjust the vibration characteristics to help impurities fall off and enhance the cleaning effect. When transporting, tightening the adjusting bolt 5 can lift the cylinder 1 to prevent the device from vibrating and jumping, which could damage the parts.

[0028] Working Principle: When the cleaning program is started, the water pump 9 located outside the cylinder 1 begins to work. The water pump 9 draws cleaning water from the water storage tank 8 located inside the base 2 via its input connection pipe. The water storage tank 8 pre-stores sufficient clean water or prepared cleaning solution to meet the cleaning requirements. Under the power of the water pump 9, the water overcomes pipe resistance and is continuously transported along the water delivery pipe 10 until it reaches the water delivery ring 11. The water delivery ring 11, as a ring-shaped structure surrounding the outside of the cylinder 1, acts as a hub for diverting and evenly distributing the water flow, smoothly distributing the cleaning solution delivered by the water pump 9 to each of its external nozzles 12. After receiving the cleaning solution diverted by the water delivery ring 11, the nozzles 12 spray water or cleaning solution onto the screen 7 inside the cylinder 1 and the surrounding cylinder walls according to the pre-designed spray angle and pressure. The water flow, in the form of fine columns or mist, impacts the screen 7. Using its kinetic energy, it disperses material particles and impurities adhering to the pores and surface of the screen 7, removing them from the screen. Simultaneously, it washes away dirt and grime accumulated inside the cylinder 1 due to material splashing and buildup. The water flow's entrainment force carries these washed-away impurities and grime towards the bottom of the cylinder 1. The resulting wastewater, carrying a large amount of impurities, flows through a specific channel at the bottom of the cylinder 1 into the return pipe 13 connected to the cylinder 1, guiding the wastewater to the filter box 14. Inside the filter box 14, the filter screen 15 plays a crucial interception role, effectively trapping solid particles, larger material fragments, and other impurities in the wastewater based on the mesh size. This ensures that only relatively clean water can pass through the filter screen 15 and enter subsequent stages. After being filtered and purified, the water is returned to the storage tank 8 through the conveying pipe 16 fixedly connected inside the filter box 14, so as to realize the recycling of cleaning water, which not only ensures a continuous supply of cleaning water, but also avoids water waste.

[0029] A combination of a female seat 4 and an adjusting bolt 5 is located at the top edge of the base 2. During normal operation of screening or cleaning, rotating the adjusting bolt 5 changes the contact degree between it and the bottom of the cylinder 1, adjusting the compression state of the spring 6, thereby flexibly changing the vibration characteristics of the entire vibrating screen. Appropriate vibration combined with water flushing can loosen and remove more stubborn impurities from the screen 7 and the inner wall of the cylinder 1, enhancing the cleaning effect. Moreover, during equipment transportation, tightening the adjusting bolt 5 lifts the cylinder 1 upwards, and this support and limiting effect prevents the device from vibrating and jumping due to road bumps, thus avoiding damage to components. The motor 18 and its two end counterweights 22, as the vibration source of the vibrating screen, also play a synergistic role in adjusting the vibration intensity to achieve multi-level adjustment, helping to improve the overall operational adaptability and cleaning efficiency of the equipment during the cleaning stage.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
