Description

Technical Field

[0001] This utility model relates to the field of mineral powder equipment technology, and more particularly to a mineral powder finished product transportation device. Background Technology

[0002] Mineral powder is a general term for stone powder and its substitutes that meet engineering requirements. It is the product of ore crushing and processing, and is the first step in ore processing and smelting. After processing, the mineral powder enters a temporary storage silo. A conveyor belt is installed below the silo, and a discharge pipe is installed at the bottom of the silo. A valve is installed on the discharge pipe; when the valve is opened, the mineral powder in the temporary storage silo is transferred to the conveyor belt through the discharge pipe. The conveyor belt then transfers the mineral powder to the next process (such as...). Figure 4 (As shown); however, the existing discharge pipes are all installed vertically at the bottom of the temporary storage bin. When the switch valve is opened, the mineral powder falls directly from a height onto the conveyor belt. The falling mineral powder will splash everywhere after hitting the conveyor belt. The splashed mineral powder is easy to fall outside the conveyor belt, causing waste of mineral powder. Utility Model Content

[0003] The purpose of this utility model is to provide a mineral powder finished product transportation device to solve the problem in the above-mentioned background technology that mineral powder falling directly from a height onto the conveyor belt easily causes wear on the surface of the conveyor belt and mineral powder splashing.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a mineral powder finished product transportation device, which is installed between a mineral powder tank and a conveyor belt, including a connecting pipe and a vertically arranged discharge pipe, a transition pipe that runs through the connecting pipe and the discharge pipe, the transition pipe being inclined between the connecting pipe and the discharge pipe, a conveyor belt being arranged directly below the discharge pipe, and a dust cover being slidably arranged on the discharge pipe. Under normal conditions, the dust cover is far away from the conveyor belt, and during use, the dust cover is close to the conveyor belt.

[0005] The beneficial effects of this solution are as follows: By setting an inclined transition pipe between the connecting pipe and the discharge pipe, when the mineral powder falls from the connecting pipe to the transition pipe, the inclined structure of the transition pipe causes the mineral powder to slide down along the pipe wall, effectively slowing down the falling speed of the mineral powder; at the same time, a dust cover is slidably installed on the discharge pipe. During use, the dust cover is close to the conveyor belt. When the mineral powder comes into contact with the conveyor belt, the splashed mineral powder is collected by the dust cover, thereby preventing the splashed mineral powder from falling outside the conveyor belt and causing waste of mineral powder. Under normal conditions, the dust cover is far away from the conveyor belt, so that the conveyor belt does not interfere with the dust cover when conveying other materials.

[0006] In a preferred embodiment of this application, an air outlet pipe is fixedly installed inside the connecting pipe. The air outlet pipe is close to the connection between the connecting pipe and the transition pipe. Several air nozzles are provided on the air outlet pipe. The center line of the air nozzles is parallel to the axis of the transition pipe. An air inlet pipe is provided on the air outlet pipe and is connected to the air nozzles. The air inlet pipe extends outside the connecting pipe and is connected to a fan.

[0007] The beneficial effects of this solution are as follows: Since the transition pipe is inclined, when the mineral powder enters the transition pipe from the connecting pipe, the speed of the mineral powder in the transition pipe decreases, which causes some of the mineral powder to adhere to the side wall of the transition pipe. When the air generated by the blower enters the air inlet pipe and then enters the transition pipe from the air outlet, it provides thrust to the mineral powder adhering to the side wall of the transition pipe, causing the mineral powder adhering to the side wall of the transition pipe to move towards the discharge pipe, thus avoiding the accumulation of mineral powder in the air inlet pipe and the connecting pipe.

[0008] As a preferred embodiment of this application, an arc-shaped baffle is provided on the outer surface of the air outlet duct; one end of the baffle is fixedly connected to the connecting pipe, and the other end of the baffle extends into the transition pipe and forms an air outlet groove between the baffle and the inner wall of the transition pipe.

[0009] The beneficial effects of this solution are as follows: the baffle plate ensures that the mineral powder does not accumulate at the connection between the air outlet pipe and the connecting pipe when it passes through the air outlet pipe; since the cross-sectional area of ​​the air outlet groove is greater than the sum of the cross-sectional areas of all air outlets, the air velocity decreases when the air enters the air outlet groove from the air outlet, thereby preventing the mineral powder from floating in the transition pipe due to excessive air velocity.

[0010] In a preferred embodiment of this application, a stop ring is fixedly installed at the end of the discharge pipe, and a pull rod is rotatably installed on the outer surface of the discharge pipe. A tension nut is connected to the pull rod. When the dust cover and the tension nut abut against each other, the dust cover is away from the conveyor belt. When the dust cover and the stop ring abut against each other, the dust cover is close to the conveyor belt.

[0011] The beneficial effects of this solution are as follows: When the conveyor belt needs to transport other items, the dust cover is manually pushed towards the transition pipe, and then the pull rod is locked in the slot, so that the tension nut and the locking plate abut against each other, thereby moving the outlet of the dust cover away from the conveyor belt. The conveyor belt will not interfere with the dust cover when transporting other items. During the transportation of mineral powder by the conveyor belt, the pull rod is removed from the slot, so that the dust cover moves towards the abutment ring under the action of gravity. When the connecting plate inside the dust cover abuts against the abutment ring, the outlet of the dust cover is close to the conveyor belt, and the dust cover collects the splashed mineral powder, preventing the splashed mineral powder from falling outside the conveyor belt.

[0012] In a preferred embodiment of this application, a connecting plate is fixedly connected to the top of the dust cover, and a discharge port is provided at the bottom of the dust cover. The connecting plate is provided with an insertion hole that matches the outer diameter of the discharge pipe. The insertion hole and the discharge port are connected in a through-hole to form a diffusion channel, which is funnel-shaped.

[0013] The beneficial effects of this solution are: because the diffusion channel is funnel-shaped, when the mineral powder enters the diffusion channel from the discharge pipe, the speed at which the mineral powder falls is reduced again, further preventing the mineral powder from splashing when it comes into contact with the conveyor belt.

[0014] In a preferred embodiment of this application, two retaining plates are provided on the outer surface of the dust cover, and each retaining plate is provided with a retaining groove for the pull rod. When the retaining plate and the tensioning nut abut against each other, the pull rod is engaged in the retaining groove.

[0015] The beneficial effects of this solution are: when the dust cover is far away from the conveyor belt, the assembly only requires aligning the pull rod with the slot and inserting it, and then tightening the plate by tightening the nut to lock it in place. The operation is relatively simple and the fixing time is shortened.

[0016] In addition to the technical problems solved by the present invention, the technical features constituting the technical solutions, and the advantages brought about by the technical features of these technical solutions as described above, other technical problems that the present invention can solve, other technical features contained in the technical solutions, and the advantages brought about by these technical features will be further described in detail with reference to the accompanying drawings.

[0022] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0023] Please see Figure 1As shown, the finished mineral powder conveying device of this embodiment includes a connecting pipe 01 that is connected to the mineral powder tank. A transition pipe 02 is connected through the connecting pipe 01. A vertically arranged discharge pipe 03 is connected through the end of the transition pipe 02. A conveyor belt 13 for conveying mineral powder is arranged directly below the discharge pipe 03. After entering the connecting pipe 01, the mineral powder passes through the transition pipe 02 and the discharge pipe 03 in sequence and is then fed into the conveyor belt 13. The axis of the transition pipe 02 and the axis of the connecting pipe 01 are set at an angle α, and the axis of the transition pipe 02 and the axis of the discharge pipe 03 are set at an angle β, thereby causing the transition pipe 02 to be inclined between the discharge pipe 03 and the connecting pipe 01. By setting the transition pipe 02 at an inclination, when the mineral powder falls from the connecting pipe 01 into the transition pipe 02, the falling speed of the mineral powder is slowed down, preventing the mineral powder from falling into the conveyor belt 13 at too high a speed and causing mineral powder splashing.

[0024] Please see Figure 2 As shown, an air outlet pipe 04 is fixedly installed inside the connecting pipe 01 by welding. The air outlet pipe 04 is located near the connection between the connecting pipe 01 and the transition pipe 02. Several air nozzles 05 are provided on the air outlet pipe 04, and the center line of the air nozzles 05 is parallel to the axis of the transition pipe 02. An air inlet pipe 06 is provided on the air outlet pipe 04 and is connected to the air nozzles 05. The air inlet pipe 06 extends outside the connecting pipe 01 and is connected to a fan 07. Since the transition pipe 02 is inclined, when the mineral powder enters the transition pipe 02 from the connecting pipe 01, the velocity of the mineral powder in the transition pipe 02 decreases, causing some mineral powder to adhere to the side wall of the transition pipe 02. When the fan 07 operates, the air enters the air inlet pipe 06 and then enters the transition pipe 02 from the air outlet, providing thrust to the mineral powder adhering to the side wall of the transition pipe 02, causing the mineral powder adhering to the side wall of the transition pipe 02 to move towards the discharge pipe 03, thus preventing the mineral powder from accumulating in the air inlet pipe 06 and the connecting pipe 01.

[0025] An arc-shaped baffle 09 is provided on the outer surface of the air outlet duct 04. One end of the baffle 09 is fixedly connected to the connecting pipe 01 by welding, and the other end of the baffle 09 extends into the transition pipe 02 and forms an air outlet groove 10 between the baffle 09 and the inner wall of the transition pipe 02.

[0026] The baffle 09 ensures that mineral powder does not accumulate at the connection between the air outlet 04 and the connecting pipe 01 when passing through the air outlet 04. Since the cross-sectional area of ​​the air outlet 10 is greater than the sum of the cross-sectional areas of all air outlets, the air velocity decreases after the air enters the air outlet 10 from the air outlet, thus preventing mineral powder from floating in the transition pipe 02 due to excessive air velocity.

[0027] A dust cover 08 is slidably mounted on the discharge pipe 03 in the vertical direction. A retaining ring 11 is fixedly installed at the end of the discharge pipe 03 by welding. Two connecting seats 12 are fixedly installed on the outer surface of the discharge pipe 03. The two connecting seats 12 are arranged opposite to each other on the discharge pipe 03. A pull rod 14 is rotatably installed inside the connecting seat 12. Two clamping plates 15 are provided on the outer surface of the dust cover 08. Each clamping plate 15 is provided with a clamping groove that matches the pull rod 14. A tensioning nut 16 is threadedly connected to the pull rod 14.

[0028] The top of the dust cover 08 is fixedly connected to a connecting plate by welding, and the bottom of the dust cover 08 is provided with a discharge port. The connecting plate is provided with an insertion hole that matches the outer diameter of the discharge pipe 03. The insertion hole and the discharge port are connected to form a diffusion channel. The cross-sectional area of ​​the insertion hole is smaller than that of the discharge port, making the diffusion channel funnel-shaped. When the mineral powder enters the diffusion channel from the discharge pipe 03, the speed at which the mineral powder falls is reduced again, further preventing the mineral powder from splashing when it comes into contact with the conveyor belt.

[0029] When the conveyor belt needs to transport other items, manually push the dust cover 08 towards the transition tube 02, and then lock the pull rod 14 into the slot so that the tension nut 16 and the clamping plate 15 abut against each other, thereby moving the discharge port of the dust cover 08 away from the conveyor belt, so that the conveyor belt will not interfere with the dust cover 08 when transporting other items.

[0030] During the transport of mineral powder on the conveyor belt, the pull rod 14 is removed from the slot, causing the dust cover 08 to move towards the abutment ring 11 under the action of gravity. When the connecting plate inside the dust cover 08 and the abutment ring 11 come into contact, the discharge port of the dust cover 08 is close to the conveyor belt. Although the speed of mineral powder falling can be reduced by the inclined transition pipe 02, there will still be mineral powder splashing when the mineral powder falls into the conveyor belt from the discharge pipe 03. Since the discharge port of the dust cover 08 is close to the conveyor belt, this part of the splashed mineral powder is collected by the dust cover 08, thereby preventing the splashed mineral powder from falling outside the conveyor belt.

If the specific posture changes, the directional indicators will also change accordingly.

[0032] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
