Description

Technical Field

[0001] This utility model relates to the field of refractory brick production technology, and in particular to a convenient and clean refractory brick material conveying device. Background Technology

[0002] With the continuous popularization and development of automated, intelligent and green production in modern manufacturing, the traditional refractory materials manufacturing industry has shed its "high energy consumption and high pollution" label and is transforming and upgrading towards high-end, intelligent and green production.

[0003] The production of shaped refractory materials involves compounding premixed unshaped refractory bricks and then repeatedly pressing them on a press. To reduce labor intensity, pollution, and spillage and loss during brick transportation, the process of sending bricks from the silo to the press is currently mostly accomplished using a sealed screw feeder. The sealed screw feeder utilizes the sealing of the pipeline and a motor to drive a spiral rod located within the pipeline to rotate, transporting bricks from one end of the pipeline to the other. This effectively prevents spillage and dust during transportation, reduces environmental pollution, and improves automation.

[0004] However, since sealed screw feeders transport bricks in closed pipes, residues are easily left at the feed end of the pipe after the bricks are transported. If new bricks are fed in at this time, the new material will mix with the residues that were not completely discharged before. The mixing of different types of new and old materials will greatly affect the product quality and may even cause serious problems such as quality hazards and safety hazards. Summary of the Invention

[0005] The purpose of this invention is to provide a convenient and clean refractory brick material conveying device.

[0006] To achieve the above objectives, the present invention can adopt the following technical solution: The convenient and clean refractory brick material conveying device of this utility model includes a double-screw conveyor connected to the discharge port of the silo for conveying refractory brick material to the brick press. A discharge port is provided at the feed end of the conveying cylinder of the double-screw conveyor. The discharge port is directly below the discharge port of the silo. A U-shaped support frame is fixedly connected to the outer edge of the discharge port. The support frame has a sliding plate mechanism for horizontally pulling and opening the discharge port. A discharge sleeve for surrounding the outer periphery of the discharge port is fixedly connected to the support frame below the sliding plate mechanism. The inner side of the discharge sleeve is a through cavity for communicating with the discharge port to discharge refractory brick material. A receiving trolley is connected to the discharge end of the discharge sleeve.

[0007] Furthermore, the sliding plate mechanism consists of a horizontal groove formed on the inner wall of the support frame and a sealing plate adapted to be inserted into the horizontal groove; the thickness of the sealing plate is greater than or equal to the wall thickness of the conveying cylinder to ensure its support strength; in addition, one end of the sealing plate extends outward from the opening side of the support frame, and its extended end is folded down to form a grip handle, so as to push and pull the sealing plate to easily open or close the material outlet.

[0008] Furthermore, the discharge sleeve extends vertically downwards, and its lower part has a conical structure that is larger at the top and smaller at the bottom, which is used to gather the refractory brick material that is to be discharged through the discharge sleeve and reduce the generation of dust.

[0009] Furthermore, an observation port is provided on the side wall of the conveying cylinder above the discharge port, and a transparent sealing door is hinged to the observation port. While ensuring the sealing of the conveying cylinder, the material accumulation inside can be easily observed, and auxiliary tools can be used to reach into the observation port to clean the residual material inside the conveying cylinder. In addition, a door handle is provided on the opening and closing side of the transparent sealing door to facilitate opening and closing the transparent sealing door.

[0010] The advantages of this invention are that by opening a discharge port at the feed end of the conveying cylinder of the twin-screw conveyor and installing a support frame and a sliding plate mechanism on the discharge port, the residual refractory brick material at the feed end of the conveying cylinder after the brick material is conveyed can be easily cleaned while ensuring the normal operation of the twin-screw conveyor. This prevents the new material from mixing with the old material after entering the twin-screw conveyor, which would affect the product quality and ensure the quality of the finished refractory bricks. It also prevents the safety hazards that may exist when using refractory bricks made from a mixture of new and old materials. In addition, the discharge sleeve fixed to the support frame can effectively prevent the dust generated during brick cleaning from drifting into the factory. At the same time, the receiving trolley connected to the discharge end of the discharge sleeve collects the brick material, which can effectively reduce dust pollution in the factory and reduce brick material waste.

[0012] Figure 2 yes Figure 1 A magnified view of the connecting frame area from below. Detailed Implementation

[0013] 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.

[0014] like Figure 1 As shown, the convenient and clean refractory brick material conveying device of this utility model includes a double helix conveyor 1 connected to the lower discharge port of the refractory brick material storage silo 100. The double helix conveyor 1 is used to convey the refractory brick material in the silo 100 to the brick press for pressing refractory bricks. Specifically, it consists of a conveying cylinder, a rotating shaft with helical blades passing through the conveying cylinder, and a motor that drives the rotating shaft to rotate. The end of the conveying cylinder of the double helix conveyor 1 connected to the silo 100 is the feeding end, and the end away from the silo 100 is the discharging end. The discharging end can be directly connected to the feeding port of the brick press to convey the refractory brick material. Alternatively, a material transport vehicle 200 for transporting refractory brick material to the brick press can be placed at the discharging end of the conveying cylinder of the double helix conveyor 1, and then the material transport vehicle 200 can be used to transport the refractory brick material to the brick press.

[0015] A discharge port 2 is provided at the feed end of the conveying cylinder of the twin-helix conveyor 1. The discharge port 2 is directly below the discharge port of the hopper 100. A U-shaped support frame 3 (e.g., Figure 2 As shown, the support frame 3 has a sliding plate mechanism for horizontally pulling open and close the material outlet 2. Specifically, the sliding plate mechanism consists of a horizontal groove 4 formed on the inner wall of the support frame 3, and a sealing plate 5 adapted to be inserted into the horizontal groove 4 and sliding along the horizontal groove 4. Since the material outlet 2 is directly below the discharge port of the hopper 100, the thickness of the sealing plate 5 should be greater than or equal to the wall thickness of the conveying cylinder of the twin-screw conveyor 1 to ensure the support strength of the sealing plate 5. In addition, for ease of operation, one end of the sealing plate 5 should extend outward from the opening side of the support frame 3, and the extended end of the sealing plate 5 should be folded downward to form a grip handle 6, so as to easily grasp the grip handle 6 to push and pull the sealing plate 5, and easily complete the opening or closing of the material outlet 2.

[0016] A discharge sleeve 7 is fixedly connected to the support frame 3 below the sliding plate mechanism to surround the outer perimeter of the discharge port 2. The upper edge of the discharge sleeve 7 is fixed to the lower surface of the support frame 3, forming a cylindrical cover over the discharge port 2. The inner side of the discharge sleeve 7 is a through cavity for connecting the discharge port 2 to discharge the refractory brick material remaining at the feed end of the conveying cylinder of the twin-screw conveyor 1. Since the purpose of setting the discharge sleeve 7 is to prevent dust from being emitted and affecting the environment when the discharge port 2 discharges material, the discharge sleeve 7 is preferably set to extend vertically downward, and the lower part of the discharge sleeve 7 is designed as a conical structure that is larger at the top and smaller at the bottom. This ensures rapid discharge from the discharge port 2, and at the same time, it can gather the refractory brick material to be discharged through the discharge sleeve 7, reducing dust generation. In addition, a receiving trolley 8 should be equipped at the discharge end (i.e., the lower end) of the discharge sleeve 7. The receiving trolley 8 has an open-top receiving hopper connected to the lower end of the discharge sleeve 7. It can receive the residual refractory brick material discharged from the discharge port 2 and push it to any place, so that the received refractory brick material can be poured back into the silo 100 or directly into the brick press.

[0017] Furthermore, an observation port 9 can be opened on the side wall of the conveying cylinder of the twin-screw conveyor 1. The observation port 9 is located above the discharge port 2, and a transparent sealing door 10 is hinged to the observation port 9. While ensuring the sealing of the observation port 9, the material accumulation inside can be easily observed. At the same time, the transparent sealing door 10 can be opened, and auxiliary tools can be inserted into the observation port 9 to clean the residual material inside the conveying cylinder. In addition, to facilitate opening or closing the transparent sealing door 10, a door handle 11 that is easy to grip should be provided on the opening and closing side of the transparent sealing door 10.

[0018] When the double helix conveyor 1 is started to transport refractory bricks from the silo 100 to the transport car 200 or the brick press, the rotating shaft with helical blades in the double helix conveyor 1, driven by the motor, pushes the refractory bricks falling into the conveying cylinder from the feed end to the discharge end. After a batch of refractory bricks is transported, because the rotating shaft with helical blades continuously pushes the refractory bricks towards the discharge end, a small amount of refractory bricks will remain in the conveying cylinder because they cannot be scraped by the helical blades. At this time, the sealing plate 5 can be pulled to open the discharge port 2, so that the remaining refractory bricks will fall naturally into the receiving trolley 8 below through the discharge sleeve 7. If there is refractory bricks adhering to the conveying cylinder, the transparent sealing door 10 on the observation port 9 can be opened, and a push rod can be inserted to remove the refractory bricks adhering to the conveying cylinder. The refractory brick material inside the cylinder is pushed out through the discharge port 2, easily cleaning the refractory brick material remaining at the feed end of the conveyor cylinder after the brick material is conveyed. This prevents the new material from mixing with the old material after entering the double screw conveyor 1, which would affect the product quality and ensure the quality of the finished refractory bricks. It also prevents the safety hazards that may exist when using refractory bricks made from a mixture of new and old materials. At the same time, the discharge sleeve 7 can prevent the dust generated during the brick material cleaning from drifting into the factory building, and the receiving trolley 8 can collect the residual accumulated material and send it to the brick press, effectively reducing dust pollution in the factory building and reducing brick material waste.

[0019] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.
