Description

Technical Field

[0001] This invention relates to the field of mine bin sealing technology, and in particular to a weighing mine bin sealing connection and its installation method. Background Technology

[0002] A ore bin is a cavern or structure used for temporary storage and loading of ore. Those used to store coal are called coal bins. The bottom of the bin is generally higher than the receiving opening of the loading container or transport equipment. Opening the bin gate allows the ore to be unloaded automatically, reducing manual labor during loading and improving loading efficiency.

[0003] Ore bins come in various structural forms, including underground, semi-underground, surface, vertical, elevated, inclined, and grab bin types. The structural form depends on factors such as ore storage capacity, ore properties (e.g., particle size, moisture content, viscosity), regional natural conditions (e.g., climate, topography, engineering geology), construction costs, and technological requirements. The storage time of the ore bin should be calculated based on its effective volume. The effective volume of the ore bin refers to the volume occupied by the amount of ore that can flow out of the bin opening by gravity. Currently, the sealing connection between the weighing ore bin and the upper concrete platform is achieved by directly sealing the rubber belt with mounting bolts, relying solely on the rubber belt for sealing. This results in poor sealing performance, allowing ore powder to directly impact the sealing rubber belt, reducing its lifespan, causing environmental pollution, and compromising the overall seal once the rubber belt is damaged. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a sealing connection for a weighing ore bin and its installation method.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sealing connection for a weighing ore bin includes a sealing assembly installed on one side of a concrete wall. The sealing assembly includes an embedded groove formed in the inner wall of one side of the concrete wall, with a first rubber sealing gasket provided on the bottom inner wall of the embedded groove. An embedded steel plate layer is provided on the outer wall of the first rubber sealing gasket, and a second rubber sealing gasket is provided on the outer wall of the embedded steel plate layer. A rectangular discharge trough is formed in the outer wall of one side of the concrete wall. A conversion angle steel is snapped onto the inner wall of the rectangular discharge trough, and a steel ore bin wall is welded to the end of the conversion angle steel. Sealing baffles are provided at the top and bottom of the conversion angle steel and the steel ore bin wall. A protective assembly is provided on one side of the steel ore bin wall.

[0007] The protective component includes a positioning block fixed to the side of the pre-embedded steel plate layer, and a rectangular steel baffle with a positioning slot is inserted into the outer wall of the positioning block. A groove is opened on one side of the outer wall of the concrete wall, and a first positioning slide rail, a partition plate and a second positioning slide rail are installed in sequence on the inner wall of the groove.

[0008] Preferably, the first rubber sealing gasket, the embedded steel plate layer, and the outer wall of one side of the second rubber sealing gasket are all provided with threaded slots, and the inner wall of the threaded slots is screwed with a first fixing bolt.

[0009] By implementing the above solution, rubber sealing gaskets are installed on both the inner and outer walls of the pre-embedded steel plate layer, thereby improving the sealing effect of the double layer and greatly enhancing the airtightness of the mine bin.

[0010] Preferably, each of the two sealing baffles has a fixed bracket on its opposite outer wall, and a rectangular mounting plate is welded to one side of each fixed bracket.

[0011] With the above solution, fixed brackets are installed on both sides of the sealing baffle, which facilitates the adjustment of the rectangular steel baffle, making it easy to open and close, and saving effort.

[0012] Preferably, a hydraulic cylinder is fixed in the middle of the rectangular mounting plate, and the piston rod of the hydraulic cylinder is rotatably connected to a linkage plate. One end of the linkage plate is rotatably connected to a fixing block, and the bottom of the fixing block is welded and fixed to the rectangular steel baffle.

[0013] The above solution utilizes the extension and retraction of a hydraulic cylinder to move a rectangular steel baffle, thereby enabling quick and convenient sliding adjustment of the rectangular steel baffle and greatly facilitating its adjustment.

[0014] Preferably, the inner walls of both sides of the rectangular discharge trough are equipped with equally spaced insertion rails, and the inner walls of the insertion rails are slidably inserted with protective inserts.

[0015] By using the above solution, a removable protective plate is installed on the inner wall of the rectangular discharge chute, which can be used to set up a baffle in front of the rubber belt layer to avoid damage caused by the impact of large ore, and can greatly improve the overall sealing effect.

[0016] Preferably, a fixing shell is fixed to one side of the outer wall of the concrete wall, and a rectangular pressure plate is inserted into the inner wall of the fixing shell. The side of the fixing shell is fixed by a second fixing bolt.

[0017] The above solution utilizes the quick-connect fitting between the fixed housing and the rectangular pressure plate. After the rectangular pressure plate and the rubber strip layer are fixed, the rubber strip layer can be quickly inserted and fixed inside the fixed housing, facilitating subsequent installation.

[0018] Preferably, the inner wall of the rectangular pressure plate is bonded with a rubber strip layer, and the outer wall of the end of the rubber strip layer is a Y-shaped structure. The two ends of the Y-shaped structure are respectively bonded with a first sealing strip and a second sealing strip, and the first sealing strip and the second sealing strip are respectively inserted into the inner wall of the first positioning slide rail and the second positioning slide rail.

[0019] With the above solution, two Y-shaped sealing strips are set on the other side of the rubber belt layer. When the sealing strips are inserted into the inner wall of the positioning slide rail, the double sealing structure can greatly improve the overall firmness and sealing performance.

[0020] Preferably, the size of the rubber belt layer is larger than the size of the rectangular discharge chute, and Z-shaped sealing pressure plates are provided on both sides of the rubber belt layer.

[0021] By using the above method, Z-shaped sealing plates can be installed on both sides of the rubber belt layer to compress and fix the two sides, thereby improving the overall sealing performance.

[0022] A method for installing a sealing connection of a weighing ore bin includes the following steps:

[0023] S1: First, a pre-embedded groove is opened on the inner wall of the concrete wall, and a first rubber sealing gasket is set on the inner wall of the pre-embedded groove. Then, the pre-embedded steel plate layer is placed inside the pre-embedded groove, and a second rubber sealing gasket is wrapped on the top. The outer wall is fixed by screwing with the first fixing bolt.

[0024] S2: Further, the conversion angle steel is welded and fixed to the outer wall of the steel ore bin. Then, the fixing bracket and rectangular mounting plate are installed on the side of the sealing baffle. After that, the hydraulic cylinder is connected to the rectangular steel baffle. After connecting to the outer wall, the extension of the hydraulic cylinder is used to drive the rectangular steel baffle to slide. The rectangular steel baffle slides continuously and stops when the positioning slot is aligned with the positioning block.

[0025] S3: After completion, fix equally spaced insertion rails on the inner walls of both sides of the rectangular discharge chute, and slide protective plates on the inner walls of the insertion rails.

[0026] S4: Finally, fix one end of the rubber strip to the inner wall of the rectangular pressure plate, and snap the rectangular pressure plate into the inside of the fixed housing. Fix the fixed housing and the rectangular pressure plate with the second fixing bolt. After the process, unfold the rubber strip and insert the first sealing strip and the second sealing strip at the end of the rubber strip into the inner wall of the first positioning slide rail and the second positioning slide rail respectively. Fix and press the edges of the rubber strip with Z-shaped sealing pressure plates on both sides.

[0027] The beneficial effects of this invention are as follows:

[0028] 1. This design enables rapid installation by setting a quick-connect and fixed rubber strip layer on the outer wall of the rectangular discharge chute. A Y-shaped sealing strip is set at the end of the rubber strip layer to further improve the sealing and stability of the rubber strip layer. Z-shaped sealing pressure plates are used on both sides of the rubber strip layer for compression and fixation to improve the overall sealing.

[0029] 2. This design features a sliding and adjustable rectangular steel baffle in front of the rubber belt layer of the ore bin. With the help of the extension and retraction of the hydraulic cylinder, the rectangular steel baffle can be quickly and easily slidably adjusted, making it easy to open and close. This can prevent the ore from impacting and damaging the rubber belt layer, thereby improving the overall sealing performance and safety.

[0030] 3. In this design, multiple quick-connect protective plates are installed in the gap between the rubber belt layer and the rectangular steel baffle, which can further improve the overall protection and avoid impact damage to the rubber belt layer from the ore. Attached Figure Description
