Description

Technical Field

[0001] The utility model belongs to the technical field of chemical production, and in particular relates to a slag bin slag discharge switch device. Background Art

[0002] Slag is a byproduct of yellow phosphorus production, produced in large quantities and serving as a crucial raw material for downstream processes. Phosphate rock, white coal, and silica react in an electric furnace. The remaining slag is quenched with water to form granules. After initial filtration, it is transported by belt conveyor to a slag bunker for storage. When needed, it is deposited into a carriage via a slag discharge device at the bottom of the bunker and then transported by truck to the next stage of production.

[0003] Currently, slag discharge devices typically use large-diameter wear-resistant ball valves. While these valves can be remotely controlled, reducing the labor intensity of on-site workers, they are expensive to produce and prone to jamming during operation. After extended use, their sealing performance degrades significantly, leading to water leakage. Consequently, frequent maintenance is required in the later stages of equipment operation, increasing operating costs for yellow phosphorus production companies while also impacting their production efficiency. Therefore, it is necessary to design a slag bin discharge switch device to address these issues. Utility Model Content

[0004] The purpose of this utility model patent is to provide a slag bin slag discharge switch device, which has a low production cost and effectively solves the problems of jamming during the switching process of the slag discharge device and water leakage in the closed state.

[0005] The technical solution adopted in this utility model is:

[0006] A slag bin slag discharge switch device includes a slag bin, a motor is provided on the top of the slag bin, a screw is connected to the bottom of the motor, the screw passes through the slag bin, the bottom of the screw is connected to a plug, and a sealing layer is provided on the surface of the plug; a flange is also provided at the bottom of the slag bin, the bottom of the flange is connected to a guide rod, and the outside of the flange is connected to a baffle.

[0007] The screw rod and the plug are connected via threads.

[0008] The plug and the flange are connected via a guide rod to prevent the plug from being displaced during operation.

[0009] The sealing layer is made of elastic material and is detachable.

[0010] A baffle is provided around the flange to prevent slag from splashing when slag is discharged.

[0011] The plug is a tapered structure that is narrow at the top and wide at the bottom.

[0012] When the slag bin is closed, the sealing layer fits tightly against the inner wall of the flange.

[0013] The baffle opening is downward, and the guide rod and the plug are located on the inner side of the baffle.

[0014] The beneficial effects of the utility model are as follows:

[0015] By utilizing a conical plug and a screw drive, this utility model achieves low pressure and high torque during the closing process of the slag discharge device, effectively preventing jams. The elastic material on the plug surface tightly fits the flange in the closed state, providing a seal and preventing water leakage. The elastic material is easily replaceable, reducing production and operating costs. This utility model prevents jams and water leakage during the opening and closing of the slag discharge device, reducing production costs, improving work efficiency, and enhancing on-site working conditions.

[0018] The embodiments of the present invention will be described in detail below with reference to the examples. The following examples are only used to illustrate the present invention and should not be considered as limiting the scope of the present invention.

[0019] Example 1

[0020] like Figure 1 As shown, a slag bin slag discharge switch device includes a slag bin 3, a motor 1 is provided on the top of the slag bin 3, the bottom of the motor 1 is connected to a screw 2, the screw 2 passes through the slag bin 3, the bottom of the screw 2 is connected to a plug 7, and a sealing layer 8 is provided on the surface of the plug 7; a flange 4 is also provided at the bottom of the slag bin 3, the bottom of the flange 4 is connected to a guide rod 6, and the outside of the flange 4 is connected to a baffle 5.

[0021] The screw rod 2 and the plug 7 are connected via threads.

[0022] The plug 7 and the flange 4 are connected via a guide rod 6 to prevent the plug from being displaced during operation.

[0023] The sealing layer 8 is made of elastic material and is detachable.

[0024] A baffle 5 is provided around the flange 4 to prevent slag from splashing when slag is discharged.

[0025] The plug 7 is a tapered structure that is narrow at the top and wide at the bottom.

[0026] When the slag bin 3 is closed, the sealing layer 8 is in close contact with the inner wall of the flange 4 .

[0027] The baffle 5 opens downward, and the guide rod 6 and the plug 7 are located on the inner side of the baffle 5 .

[0028] Example 2

[0029] The working principle of this utility model is as follows:

[0030] A motor 1 is mounted on top of the slag bin 3. Controlling the forward and reverse rotation of the motor 1 drives the screw 2, which is connected to the plug 7 at its lower end. The screw 2 rotates, raising and lowering the plug 7. A sealing layer 8 on the surface of the plug 7, made of an elastic material, provides a seal. The slag bin 3 contains a mixture of slag and water. When closed, the sealing layer 8 on the surface of the plug 7 fits tightly against the inner wall of the flange 4, preventing leakage. The sealing layer 8 is removable, allowing for timely replacement if wear affects the seal, reducing production costs. When the slag bin 3 is open, material flows out of the flange 4. A baffle 5 installed around the flange 4 blocks the slag-water mixture, preventing it from splashing along the tapered surface of the plug 7 and converging it, facilitating loading operations. A guide rod 6 is fixed between the flange 4 and the plug 7, guiding the plug 7 as it rises and falls, preventing displacement during operation.
