Description

Technical Field

[0001] The utility model belongs to the field of belt conveyor equipment accessories, is used for ore dressing and conveying, and specifically relates to a three-way powder material funnel. Background Art

[0002] As a mineral processing conveying equipment, the belt conveyor is mainly responsible for the conveying and transfer of ore. It is a kind of transportation machinery that continuously transports materials by the friction between the belt and the transmission roller, forming a material flow path from the starting feeding point to the final drop point. The belt conveyor can not only transport scattered materials, but also transport objects in batches, so the belt conveyor has been widely used in modern industrial enterprises. The head three-way funnel plays a vital role in the entire belt conveyor. It is one of the most important components and is the link and bridge connecting two adjacent conveyors.

[0003] Generally, the three-way funnel is made of welded steel plates. When one conveyor unloads to two belt conveyors or there are two unloading points, the three-way funnel must be used to realize the transfer and diversion of materials. The three-way funnel is convenient for switching the conveying channel, and secondly, it ensures that when a conveying channel in operation fails, another channel can be put into use quickly and in time, so as to meet the needs of continuous operation of the equipment.

[0004] Its structure mainly includes a feed port at the top and two discharge ports at the bottom. Its working principle is that the electric flap is equipped with a baffle driven by a hydraulic electric push rod. The flap rotates around the shaft fixed below the feed port. The material flows in through the feed port in the position shown in the figure, and the material impacts on the flap. When the flap is in the initial position, the material flows from the feed port to the discharge port 2. When it is necessary to switch to another belt conveyor, start the electric push rod. When the electric push rod moves to the maximum stroke, it is blocked by the block. The flap reaches the end position at this time, and the material in the feed port flows into the discharge port 1. In this way, you can repeatedly switch which material port to flow into, thereby achieving the effect of a three-way funnel.

[0005] However, there is usually a certain gap between the flap and the side wall of the funnel. During the operation of the conveyor, materials will inevitably flow out of this gap. Over time, the gap will accumulate. Cleaning materials must be frequent, which requires continuous investment of manpower and material resources. The cleaning process will inevitably affect the normal operation of the equipment and the normal production of the enterprise. In addition, the two sides of the flap are often eroded and hit by materials, and there is a certain distance between the flap and the conveyor head roller. The specific gravity of the conveyed ore material is relatively large. This will cause the three-way flap to wear during long-term use, shortening its service life. A certain amount of manpower, material and financial resources need to be invested in the replacement process. In addition, the three-way funnel body will also be worn by the material that rebounds after hitting the baffle. Utility Model Content

[0006] The present application provides a three-way material distribution funnel, which improves the flap structure and increases the service life of the funnel.

[0007] In order to achieve the above technical objectives, the technical solution adopted by the present application is a three-way material distribution funnel, including a funnel body, wherein the three-way material distribution funnel body includes a feed port and a first discharge port and a second discharge port located below the feed port; and

[0008] A flat gate is located in the three-way material distribution funnel body and below the feed port, and has a state of closing the first discharge port or the second discharge port;

[0009] The electro-hydraulic push rod is located outside the three-way material distribution funnel body and is connected to the flat gate to drive the flat gate to move horizontally so as to switch between the state of closing the first discharge port and the state of closing the second discharge port.

[0010] Preferably, there are also limit switch 1 and limit switch 2; the limit switch 1 controls the first limit position of the electro-hydraulic push rod to be the limit position of pushing the flat gate to close the discharge port 1, and the limit switch controls the electro-hydraulic push rod to push the flat gate to close the discharge port 2.

[0011] Preferably, the surface of the flat gate is covered with a wear-resistant layer.

[0012] Preferably, the flat plate gate adopts a material storage box structure, including a flat plate and baffles located around the flat plate, and the height of the baffles is lower than the height of the three-way material distribution funnel body.

[0013] Preferably, the height of the baffle is between 5-15 cm.

[0014] Preferably, an opening is provided on the side of the three-way material distribution funnel body, and the end of the flat gate passes through the opening and is driven by the electro-hydraulic push rod.

[0015] Preferably, a roller is provided below the flat gate, and slide grooves are provided at the top and bottom of the opening respectively; when the electro-hydraulic push rod pushes the flat gate, the roller slides along the slide grooves.

[0016] Beneficial Effects

[0017] The present application adopts a flat gate instead of a flap to control a three-way material distribution funnel, so that the three-way material distribution funnel has a long service life, few failures, and can be remotely controlled automatically. It effectively solves the shortcomings of the flap-type three-way intermediate gate being easily worn by the impact of materials, having a high failure rate, a long maintenance time, high cost, and affecting production operations.

[0023] The present application provides a three-way funnel transformed by using an electro-hydraulic flat gate, in which the flat gate is used to replace the flap gate.

[0024] A three-way material distribution funnel, comprising a three-way material distribution funnel body 1, wherein the three-way material distribution funnel body 1 comprises a feed port 2 and a first discharge port 3 and a second discharge port 4 located below the feed port 2; and further comprising

[0025] The flat gate 5 is located in the three-way material distribution funnel body 1 and below the feed port 2, and has a state of closing the discharge port 1 3 or the discharge port 2 4;

[0026] The electro-hydraulic push rod 6 is located outside the three-way material distribution funnel body 1 and is connected to the flat gate 5 to drive the flat gate 5 to move horizontally to switch between the state of closing the discharge port 1 3 and the state of closing the discharge port 2 4 .

[0027] In order to ensure the safety of the operation of the electro-hydraulic push rod 6, a limit switch 1 and a limit switch 2 are also provided; the limit switch 1 controls the first limit position of the electro-hydraulic push rod 6 to be the limit position of pushing the flat gate 5 to close the discharge port 1 3, and the limit switch 2 controls the limit position of the electro-hydraulic push rod 6 to push the flat gate 5 to close the discharge port 2 4. The action of the limit switch is used to control the motor of the electro-hydraulic push rod 6 to stop. The limit switch 1 and the limit switch 2 are installed in appropriate positions. When the flat gate 5 completely closes the discharge port 1 3 or the discharge port 2 4, the block at the head of the electro-hydraulic push rod 6 can be used to touch the limit switch to stop the operation of the flat gate 5. The switching between the discharge port 1 3 and the discharge port 2 4 is completed, and the safe operation of the flat gate 5 is protected, and the electro-hydraulic push rod 6 can be prevented from continuing to operate and damaging the three-way material distribution funnel.

[0028] In order to increase the service life of the flat gate 5 , the surface of the flat gate 5 is covered with a wear-resistant layer, which forms double protection with the materials accumulated on the flat gate 5 . The main purpose is to reduce the wear of the flat gate 5 and extend the service life of the flat gate 5 .

[0029] Of course, in order to improve the service life of the flat gate 5, the flat gate 5 can adopt a material storage box structure, including a flat plate and baffles 7 located around the flat plate, and the height of the baffles 7 is lower than the height of the three-way material distribution funnel body 1. The preferred height of the baffle 7 is 5-15 cm, and the most preferred is 10 cm.

[0030] In the method of the electro-hydraulic push rod 6 pushing the flat gate 5, an opening is provided on the side of the three-way material distribution funnel body 1, and the flat gate 5 passes through the opening and is driven by the electro-hydraulic push rod 6. In this method, in order to avoid dust, a partition can be installed at the position where the flat gate 5 is located inside the three-way material distribution funnel body 1, and the length of the partition is 3 / 4 of the length of the three-way material distribution funnel, so as to ensure that when the electro-hydraulic push rod 6 pushes the flat gate 5 to slide, the opening on the three-way material distribution funnel is always closed.

[0031] Preferably, a roller is provided below the flat gate 5, and slide grooves are provided at the top and bottom of the opening respectively; when the electro-hydraulic push rod 6 pushes the flat gate 5, the roller slides along the slide grooves.

[0032] Example 1

[0033] A three-way funnel is transformed by using an electro-hydraulic flat gate to replace a flap gate. Specifically, a three-way material distribution funnel is provided, comprising a three-way material distribution funnel body 1, wherein the three-way material distribution funnel body 1 comprises a feed port 2 and a first discharge port 3 and a second discharge port 4 located below the feed port 2; the feed port 2 is used to feed the first discharge port 3 and the second discharge port 4, the feed port 2 is located above the first discharge port 3 and the second discharge port 4, and the feed port 2, the first discharge port 3, and the second discharge port 4 are in a herringbone shape.

[0034] It also includes a flat gate 5, which is located in the three-way material distribution funnel body 1 and below the feed port 2, and has a state of closing the discharge port 1 3 or the discharge port 2 4. When the discharge port 1 3 is closed, the feed of the feed port 2 falls on the flat gate 5 and accumulates on the flat gate 5 to form a buffer layer. When the accumulated amount of feed is sufficient, the feed will slide from the flat gate 5 into the discharge port 2 4; when the discharge port 2 4 is closed, similarly, the material slides from the flat gate 5 into the discharge port 1 3.

[0035] The electro-hydraulic push rod 6 is located outside the three-way material distribution funnel body 1. The electro-hydraulic push rod 6 is installed on both sides of the outside of the three-way material distribution funnel to protect the electro-hydraulic push rod 6 from contacting the mineral. It is connected to the flat gate 5 to drive the flat gate 5 to move horizontally to switch between closing the discharge port 1 3 and closing the discharge port 2 4. The electro-hydraulic push rod 6 is a motor + oil pump + hydraulic oil combined motion mechanism, which must have a matching electronic control system to control the start and stop of the forward and reverse rotation of the motor to realize the linear telescopic operation of the push rod.

[0036] The flat gate 5 controls the three-way material distribution funnel. Two electro-hydraulic push rods 6 are installed on both sides of the flat gate 5 to achieve horizontal movement of the flat gate 5 and switch between the two discharge ports. Working principle: 1. When the piston rod of the electro-hydraulic push rod 6 is retracted ( Figure 2 ), the flat gate 5 blocks the left outlet, the discharge port 1 3 is closed, and the material is discharged from the discharge port 2 4. A part of the material accumulates on the flat gate 5 to protect the flat gate 5 from wear. 2. When the piston rod of the electro-hydraulic push rod 6 extends ( Figure 3 ), the flat gate 5 blocks the right outlet, the discharge port 2 4 is closed, and the material is discharged from the discharge port 1 3, realizing the switching work of the three-way material distribution funnel.

[0037] At the front end of the electro-hydraulic push rods 6 on both sides, the travel switch is used to control the running distance of the push-pull rod to ensure that the flat gate 5 effectively controls the material outlet and switching. The specific implementation is that the three-way material distribution funnel also has a limit switch 1 and a limit switch 2; the limit switch 1 controls the first limit position of the electro-hydraulic push rod 6 to push the flat gate 5 to close the discharge port 1 3, and the limit switch controls the electro-hydraulic push rod 6 to push the flat gate 5 to close the discharge port 2 4. Two limit switches are installed at the front and rear positions of the piston rod head stroke of the electro-hydraulic push rod 6, and the switching work of the flat gate is completed by using the action of the limit switch and the electrical control system. That is, the action of the limit switch is used to control the stop of the electro-hydraulic push rod motor. In combination with Example 1, the limit switch 1 and the limit switch 2 are respectively installed at the middle position outside the three-way material distribution funnel corresponding to the discharge port 1 3 and the discharge port 2 4 (when the flat gate 5 stops, it can completely close the discharge port 1 or the discharge port 2 respectively).

[0038] When the electro-hydraulic push rod 6 retracts backward (lower Figure 2 When the flat gate 5 completely closes the discharge port 3, the block at the head of the electro-hydraulic push rod 6 touches the limit switch 1, and the action of the limit switch 1 is used to disconnect the control power of the motor, so that the electro-hydraulic push rod 6 stops contracting and the flat gate 5 stops.

[0039] When the electro-hydraulic push rod 6 extends forward (lower Figure 4When the flat gate 5 completely closes the discharge port 2 4, the block at the head of the electro-hydraulic push rod 6 touches the limit switch 2, and the action of the limit switch 2 is used to disconnect the control power of the motor, so that the electro-hydraulic push rod stops contracting and the flat gate 5 stops.

[0040] The surface of the flat gate 5 is covered with a wear-resistant layer to increase the service life of the flat gate 5 .

[0041] Example 2

[0042] The difference from the first embodiment is that the gate of the flat gate 5 is transformed into a material storage box structure ( Figure 4 The material storage box structure includes a flat plate and baffles 7 located around the flat plate, and the height of the baffles is lower than the height of the three-way material distribution funnel body 1. The preferred height of the baffle 7 is 5-15 cm, and the most preferred height is 10 cm.

[0043] During operation, materials will accumulate on the material box to form a protective layer to protect the flat gate 5 from impact and wear.

[0044] The upper part of the original flat gate 5 is transformed into a storage hopper, and the natural accumulation angle of repose of the material during the falling process is used to form a protective layer. In the actual production and operation process, the impact buffer between the materials is formed to protect the gate body and extend the service life of the gate.

[0045] Example 3

[0046] The method that is superior to Example 1 and Example 2 is that the electro-hydraulic push rod 6 pushes the flat gate 5, and an opening is provided on the side of the three-way material distribution funnel body 1, and the end of the flat gate 5 passes through the opening and is driven by the electro-hydraulic push rod 6. In this method, in order to avoid dust, a partition can be installed at the position where the flat gate 5 is located inside the three-way material distribution funnel, and the length of the partition is 3 / 4 of the length of the three-way material distribution funnel, so as to ensure that when the electro-hydraulic push rod 6 pushes the flat gate 5 to slide, the opening on the three-way material distribution funnel is always closed. The purpose of setting the partition of the three-way material distribution funnel body is to reduce the leakage of powdered materials, and the old conveyor belt (as a partition) can be used to close the gap between the flat gate and the funnel.

[0047] Preferably, a roller is provided below the flat gate 5, and slide grooves are provided at the top and bottom of the opening respectively; when the electro-hydraulic push rod pushes the flat gate, the roller slides along the slide grooves.
