Description

Technical Field

[0001] This utility model relates to the field of separation device technology, specifically a sand and gravel separator for mining. Background Technology

[0002] The mining machinery industry is an important basic industry that serves many key industrial sectors. Among them, sand and gravel separators used in mining are crucial for ensuring the quality of sand and gravel, but current separators have many problems.

[0003] Existing sand and gravel separators for mining perform poorly in dust handling. During sand and gravel separation, a large amount of dust is generated and cannot be effectively controlled. This dust spreads freely in the working environment, severely polluting the air, reducing workplace air quality, threatening the health of operators, obstructing visibility, creating safety hazards, and causing multiple negative impacts on mining operations. Furthermore, the varying moisture content of the sand and gravel affects the screening speed, and existing separators cannot adjust the feed flow rate accordingly. When the sand and gravel have high moisture content, the screening speed slows down. If the feed flow rate is not adjusted accordingly, it will lead to screening blockage, further reducing separation speed and efficiency, failing to meet the needs of mining production, increasing production costs, and hindering industry development. Therefore, the development of a new type of sand and gravel separator is essential. To this end, we have proposed a sand and gravel separator for mining. Utility Model Content

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] A sand and gravel separator for mining is provided, which has the following advantages:

[0017] 1. High-efficiency dust removal: The side dust removal fan in the dust removal component sucks the dust generated during the separation process into the dust guide pipe. The dust enters the dust collection box along the pipe, effectively preventing the dust from spreading in the working environment. This not only improves the air quality in the workplace and protects the health of operators, but also reduces the interference of dust on vision, reduces safety hazards, and creates a safer and cleaner environment for mining operations.

[0018] 2. Optimize separation efficiency: The feeding control component can adjust the feed flow rate according to the moisture content of the sand and gravel and the screening speed. When the moisture content of the sand and gravel is high, which causes the screening speed to slow down, the feeding drive cylinder can be controlled to push the feeding drive push rod to move the feeding slide plate, reduce the feed amount at the feed inlet, avoid screening blockage, maintain the efficient operation of the separator, meet the needs of mine production, and reduce production costs.

[0019] 3. Convenient discharge: The discharge drive motor of the discharge control component drives the discharge rotating plate to rotate. After separation is completed, by controlling the rotation angle of the discharge rotating plate, the separated stone can be smoothly discharged from the discharge hole to the stone collection box. The operation is simple and convenient, improving the efficiency and accuracy of discharge. Attached Figure Description

[0033] Structural Description:

[0034] Separation support frame 1: As the basic support structure of the entire equipment, separation support frame 1 provides a platform for the installation and fixing of other components. The feed port 13 on its top surface is used for sand and gravel to enter, the side connecting hole 14 at the front provides a channel for dust to enter the dust guide pipe 7, the motor support platform 5 at the front is used to install the discharge drive motor 4, and the rotating support platform 15 on the side provides rotation support for the discharge rotating plate 2.

[0035] Feed storage frame 11: Fixed to the top side of the top support plate 12, used to store sand and gravel to be separated. Its bottom is in cooperation with the discharge control component. Under the action of the discharge control component, sand and gravel are conveyed into the separator through the feed port 13.

[0036] Stone collection box 3: fixed to the bottom side of the separation support frame 1, used to collect the separated stone discharged from the discharge control component;

[0037] Discharge slide plate 8: slides on the top surface of the separation support frame 1. Its shape and size match the feed inlet 13 and the sliding track on the top surface of the separation support frame 1. It is usually flat and has a smooth surface to reduce the resistance when the sand and gravel slide. One end is fixedly connected to the discharge drive push rod 10. By pushing or pulling the discharge drive push rod 10, the opening degree of the feed inlet 13 can be adjusted, thereby controlling the feed flow rate.

[0038] Discharge drive cylinder 9: Fixed on the top surface of the separation support frame 1, it has a piston and piston rod inside. The piston can slide up and down in the cylinder. The movement of the piston is controlled by air intake and exhaust, which in turn drives the piston rod, that is, the discharge drive push rod 10 to extend and retract. The cylinder body material of the discharge drive cylinder 9 usually has high strength and wear resistance to ensure reliability under frequent operation.

[0039] Discharge drive push rod 10: One end is connected to the piston rod of the discharge drive cylinder 9, and the other end is fixed to the discharge slide plate 8. Its length and diameter are designed according to the stroke of the discharge drive cylinder 9 and the force requirements of the discharge slide plate 8. It is usually a rod-shaped structure with a certain rigidity to ensure that it will not bend or deform when pushing the discharge slide plate 8, thus ensuring the accuracy of feeding control.

[0040] Discharge rotating plate 2: It rotates inside the rotating support platform 15. Its shape is usually a fan shape or part of a circle. Its size is adapted to the discharge hole on the side of the separation support frame 1 and the rotating support platform 15. Its surface is smooth to reduce the friction when the stone is discharged. The part that is fixedly connected to the output shaft of the discharge drive motor 4 is designed with a keyway or other connection structure to ensure that the discharge rotating plate 2 can rotate synchronously with the motor output shaft to realize the discharge function.

[0041] Discharge drive motor 4: Installed on the top surface of motor support platform 5, it is the power source of the discharge control component. The motor has a stator, rotor and other structures inside. It converts electrical energy into mechanical energy to drive the output shaft to rotate. Its power is selected according to factors such as the discharge speed and the weight of the stone to ensure that it can provide enough power to drive the discharge rotating plate 2 to rotate and achieve efficient discharge.

[0042] Dust collection box 6: Fixed to the front of the separation support frame 1, used to collect dust. The interior is a closed box structure with a certain volume. The box wall is usually sealed to prevent dust leakage. The part connected to the dust guide pipe 7 is designed with an interface or pipe connection structure to ensure that the dust can enter the collection box smoothly. The bottom can be designed as a detachable structure or with a cleaning port to facilitate regular cleaning of the collected dust.

[0043] Dust guiding duct 7: Connects the side connecting hole 14 and the dust collection box 6. It is usually a tubular structure. Its diameter is designed according to the amount of dust generated and the suction power of the side dust removal fan 19. The inside of the duct is smooth to reduce the adhesion and blockage of dust in the duct. The connection between the side connecting hole 14 and the dust collection box 6 adopts a sealed connection method, such as welding or using sealing rings, to ensure that dust does not leak.

[0044] Side dust removal fan 19: Installed in the mounting hole on the back of the separate support frame 1, it consists of a motor, fan blades and a protective net. The motor drives the fan blades to rotate, generating suction to draw dust into the dust guide pipe 7. The shape and angle of the fan blades are designed to improve dust collection efficiency. The protective net is used to prevent foreign objects from entering the fan, protect the motor and fan blades, and ensure the safety of the operator.

[0045] Internal gravel collection box 16: It slides on the bottom surface inside the separation support frame 1 and is used to collect small particles of sand and gravel after separation. Its shape is usually a rectangular box. The size of the internal space is designed according to the processing capacity of the separator. The bottom is designed with a chute or roller that matches the bottom surface inside the separation support frame 1, which facilitates cleaning and transportation after a certain amount of sand and gravel is collected.

[0046] Internal separation drive cylinder 17: Fixed inside the separation support frame 1, its internal structure is similar to that of the discharge drive cylinder 9, including piston, piston rod, etc. The piston movement is controlled by air intake and exhaust, which drives the internal separation drive push rod 18 to extend and retract. Its cylinder body material and sealing performance are required to ensure stability and reliability under frequent operation.

[0047] Internal separation drive push rod 18: One end is connected to the piston rod of the internal separation drive cylinder 17, and the other end is fixed to the separation screening plate 20. Its structural design ensures rigidity and stability when pushing the separation screening plate 20. It is usually rod-shaped, and its length and diameter are determined according to the stroke of the internal separation drive cylinder 17 and the force requirements of the separation screening plate 20.

[0048] Separation screening plate 20: It slides inside the separation support frame 1, and the top surface is provided with equally spaced separation grooves 21. The shape and size of the separation grooves 21 are designed according to the particle size of the sand and gravel and the separation requirements. They are usually strip-shaped or circular with moderate depth to ensure that small particles of sand and gravel can pass through smoothly, while large particles of sand and gravel remain on the plate. The material of the separation screening plate 20 usually has high strength and wear resistance to ensure that it will not be deformed or damaged during long-term use.

[0049] Working principle: When this utility model is needed, sand and gravel are pre-stored in the feed storage frame 11. When separation is required, the discharge control component is activated, and the discharge drive cylinder 9 pulls the discharge drive push rod 10, which in turn drives the discharge slide plate 8 to slide on the top surface of the separation support frame 1. Since the discharge port and feed port 13 of the feed storage frame 11 are aligned, after the discharge slide plate 8 moves, the sand and gravel can enter the separator from the feed port 13. Moreover, the position of the discharge slide plate 8 can be precisely adjusted by controlling the extension and retraction of the discharge drive cylinder 9 according to the sand and gravel moisture and screening speed, thereby controlling the feed amount and avoiding screening blockage. The sand and gravel entering the separator fall onto the separation screening plate 20. The top surface of the separation screening plate 20 has equally spaced separation grooves 21. The internal separation drive cylinder 17 drives the internal separation drive push rod 18, causing the separation screening plate 20 to slide up and down inside the separation support frame 1. During the sliding process, smaller sand and gravel particles fall into the internal gravel collection box 16 below through the separation groove 21, while larger sand and gravel particles remain on the separation screening plate 20, achieving separation of sand and gravel according to particle size. The dust generated during the separation process is drawn into the dust guide pipe 7 through the side connecting hole 14 in front of the separation support frame 1 by the suction of the side dust removal fan 19. The dust guide pipe 7 is connected to the dust collection box 6, and the dust is collected in the dust collection box 6 along the pipe, effectively preventing the spread of dust in the working environment and improving the quality of the working environment. After the separation is completed, the discharge control component is activated, and the discharge drive motor 4 drives the discharge rotating plate 2 to rotate around the rotating support platform 15. When the discharge rotating plate 2 rotates to a suitable angle, the stone material separated on the separation screening plate 20 is discharged from the discharge hole on the side of the separation support frame 1 and falls into the stone collection box 3, completing the discharge operation.
