Detailed Embodiment

[0025] To enable those skilled in the art to better understand the technical solution of the present utility model, the present utility model will be further described in detail below in conjunction with the accompanying drawings.

[0026] As Figures 1-5 shown, a feeding and conveying device for an electrofused brick grinding machine includes a conveyor belt 1;

[0027] A sliding frame 13 for carrying the conveyor belt 1;

[0028] A frame 2 which is slidably matched with the sliding frame 13;

[0029] A dust baffle 31 is arranged on the frame 2, and a nozzle 33 pointing to the conveyor belt 1 is arranged inside the dust baffle 31;

[0030] Wherein, a telescopic bladder 22 for maintaining a predetermined distance is arranged between the frame 2 and the sliding frame 13, and the telescopic bladder 22 is communicated with the nozzle 33 to enable the nozzle 33 to spray water.

[0031] Specifically, both ends of the telescopic bladder 22 are respectively arranged on the frame 2 and the sliding frame 13. A water tank 37 is also arranged on the frame 2 to supply water to the nozzle 33. The sliding direction of the sliding frame 13 is perpendicular to the transmission direction of the conveyor belt 1. This sliding direction is the width direction of the sliding frame 13 and the frame 2. And baffles are arranged on both sides of the bottom of the sliding frame 13 to prevent it from detaching from the frame 2. The sliding frame 13 can be reciprocally slid on the frame 2 along the width direction by an electric telescopic rod or manually pushing and pulling, so that the electrofused bricks on the conveyor belt 1 reciprocally shake with the conveyor belt 1, shaking off the dust and debris on the electrofused bricks. And during the sliding process of the sliding frame 13, the distance between it and the frame 2 continuously changes, causing the telescopic bladder 22 to repeatedly expand and contract. When the telescopic bladder 22 stretches, its internal volume becomes larger, sucking in the outside air into the interior of the telescopic bladder 22. When it contracts, it squeezes the internal gas into the connected nozzle 33, making the gas flow rate in the nozzle 33 increase, forming a negative pressure to suck the liquid in the water tank 37, and spraying the liquid when releasing the gas, wetting the surface of the electrofused bricks through the nozzle 33, facilitating subsequent grinding. And the setting of the dust baffle 31 can reduce the escape of dust and limit the spraying range of the nozzle 33.

[0032] In the above technology, the sliding frame 13 drives the conveyor belt 1 to reciprocally shake, thereby shaking off the dust and debris on the electrofused bricks. Cooperating with the water spraying of the nozzle 33, the dust is settled by the water mist, reducing the dust during the conveying process. And after the electrofused bricks are sprayed with water, the surface temperature is reduced, reducing the high heat generated by friction when being ground.

[0033] As a further embodiment provided by the present utility model, an inclined surface roller 12 is arranged on the side surface of the end of the conveyor belt 1, and a guide chute 24 for slidably assembling the inclined surface roller 12 is opened on the frame 2.

[0034] Specifically, the inclined plane roller 12 is coaxial with the turning roller on the end of the conveyor belt 1. When the conveyor belt 1 is running normally, the turning roller rotates to drive the conveyor belt 1 to run, and drives the inclined plane roller 12 to rotate in the guide chute 24. The side walls of the guide chute 24 and the inclined plane roller 12 are both inclined planes with the same inclination angle. During the rotation process, when the two inclined planes are parallel to each other, the guide chute 24 is in close contact with the inclined plane roller 12. As the inclined plane roller 12 continues to rotate, the two inclined planes are no longer parallel and present a crossed state. At this time, the inclined plane roller 12 abuts against the guide chute 24, and the distance between the sliding frame 13 and the frame 2 gradually increases, causing the telescopic bladder 22 to stretch for elastic energy storage. After the distance reaches the maximum, the telescopic bladder 22 begins to release elastic potential energy, causing the distance to gradually shorten until the guide chute 24 is in close contact with the inclined plane roller 12 again. An equidistant spring 23 for enhancing the elasticity of the telescopic bladder 22 is provided inside the telescopic bladder 22.

[0035] As another embodiment further provided by the present utility model, a roller 21 for the sliding frame 13 to slide is rotatably provided on the frame 2.

[0036] Specifically, during the rotation of the inclined plane roller 12, the sliding frame 13 reciprocally slides in the width direction on the frame 2. By means of the roller 21 rotatably provided on the frame 2, the frictional resistance between the sliding frame 13 and the frame 2 can be effectively reduced, so that the sliding frame 13 and the conveyor belt 1 can be driven to slide with a relatively small force.

[0037] As another embodiment further provided by the present utility model, a cleaning brush 38 is provided on the frame 2, and the bristles of the cleaning brush 38 extend towards the bottom side of the conveyor belt 1.

[0038] Specifically, side grooves 11 are formed on both sides of the conveyor belt 1. When the conveyor belt 1 is driven by the sliding frame 13 to reciprocally slide on the frame 2, the fused cast bricks on the conveyor belt 1 also sway back and forth, so that the debris and powder on the fused cast bricks fall onto the surface of the conveyor belt 1 and gather towards the side grooves 11 on both sides as the conveyor belt 1 sways. Since the nozzle 33 sprays water onto the conveyor belt 1, the surface of the conveyor belt 1 becomes wet. After being redirected by the turning roller at the end, the debris and powder gathered in the side grooves 11 fall off, and the upper surface of the wet conveyor belt 1 is redirected to the lower surface. When it moves to the other end, it is brushed by the cleaning brush 38 to reduce the stains on the conveyor belt 1.

[0039] As another embodiment further provided by the present utility model, the telescopic bladder 22 is communicated with an air cavity 36. A flow channel 34 communicated with the nozzle 33 is provided inside the dust baffle 31, and the air cavity 36 and the flow channel 34 are in one-way communication.

[0040] Specifically, the telescopic bladder 22 is connected to the air chamber 36 through the air duct 35 provided in the dust baffle 31. When the telescopic bladder 22 contracts, the air inside is squeezed into the air chamber 36 through the air duct 35, causing the piston movably arranged in the air chamber 36 to move downward. The spring arranged on the piston stores energy, and the liquid pressure in the flow channel 34 rises, causing the nozzle 33 to spray water on the conveyor belt 1. Subsequently, the telescopic bladder 22 stretches and sucks air from the air chamber 36, so that the elastic potential energy of the spring is released, the piston moves upward, and the water in the flow channel 34 is sucked into the air chamber 36. With the next contraction of the telescopic bladder 22, the water is sprayed out again.

[0041] As yet another embodiment further provided by the present utility model, a water collecting tank 39 for collecting waste water is provided at the bottom of the frame 2.

[0042] Specifically, a filtering and purifying device is provided in the water collecting tank 39, and the output end of the filtering and purifying device is communicated with the water tank 37. The water collecting tank 39 is located below the nozzle 33. When the nozzle 33 sprays the conveyor belt 1, part of the water will directly flow downward from the conveyor belt 1 and finally converge in the water collecting tank 39. After being filtered and purified, it is recycled into the water tank 37 to reduce waste.

[0043] Working principle: When the conveyor belt 1 runs normally, the turning roller rotates to drive the conveyor belt 1 to run, and drives the inclined surface roller 12 to rotate in the guide chute 24. The side walls of the guide chute 24 and the inclined surface roller 12 are both inclined surfaces with the same inclination angle. During the rotation, when the two inclined surfaces are parallel to each other, the guide chute 24 is in close contact with the inclined surface roller 12. As the inclined surface roller 12 continues to rotate, the two inclined surfaces are no longer parallel and present a crossed state. At this time, the inclined surface roller 12 abuts against the guide chute 24, and the distance between the sliding frame 13 and the frame 2 gradually increases, causing the expansion bladder 22 to stretch for elastic energy storage. After the distance reaches the maximum, the expansion bladder 22 begins to release elastic potential energy, causing the distance to gradually shorten until the guide chute 24 is in close contact with the inclined surface roller 12 again, enabling the sliding frame 13 to reciprocally slide in the width direction on the frame 2, so that the electrofused bricks on the conveyor belt 1 reciprocally shake with the conveyor belt 1, shaking off the dust and debris on the electrofused bricks, and gathering towards the side grooves 11 on both sides as the conveyor belt 1 shakes. Moreover, the distance between the sliding frame 13 and the frame 2 continuously changes during the sliding process, causing the expansion bladder 22 to repeatedly expand and contract. When the expansion bladder 22 contracts, the air inside is squeezed into the air chamber 36 through the air duct 35, causing the piston movably arranged in the air chamber 36 to move downward. The spring arranged on the piston stores energy, and the liquid pressure in the flow channel 34 rises, causing the nozzle 33 to spray water on the conveyor belt 1. Subsequently, the expansion bladder 22 stretches and sucks air into the air chamber 36, thereby releasing the elastic potential energy of the spring, causing the piston to move upward and sucking the water in the flow channel 34 into the air chamber 36. With the next contraction of the expansion bladder 22, the water is sprayed out again, making the surface of the conveyor belt 1 wet. After being redirected by the turning roller at the end, the debris and powder gathered in the side groove 11 fall, and the upper surface of the wet conveyor belt 1 is redirected to the lower surface. When it moves to the other end, it is scrubbed by the cleaning brush 38 to reduce the stains on the conveyor belt 1. The water collecting tank 39 is located below the nozzle 33. When the nozzle 33 sprays the conveyor belt 1, part of the water directly flows downward from the conveyor belt 1 and finally converges in the water collecting tank 39. After being filtered and purified, it is recycled into the water tank 37 to reduce waste.

[0044] Only some exemplary embodiments of the present utility model have been described by way of illustration. Undoubtedly, for those of ordinary skill in the art, without departing from the spirit and scope of the present utility model, the described embodiments can be modified in various different ways. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the protection scope of the claims of the present utility model.
