Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of chemical production equipment, and relates to magnesium material production equipment, specifically a magnesium slag discharge and conveying device. Background Technology
[0002] Magnesium processing mainly involves extracting magnesium from magnesium-bearing ores and producing industrial magnesium ingots or magnesium alloys through refining and alloying processes. Magnesium slag is a byproduct of magnesium production, primarily originating from the Pidgeon process (thermal reduction) and electrolytic magnesium smelting processes. Its complex composition and improper handling can negatively impact environmental friendliness and economic viability. Current technologies primarily employ slag collection structures to gather the magnesium slag, which is then transported to a treatment plant for centralized processing.
[0003] Magnesium slag produced by the thermal reduction method is a red-hot material discharged directly from the calcining furnace, with a temperature reaching as high as 1200℃. However, in existing technologies, the slag discharge structures used to accommodate magnesium slag are mostly made of metal, primarily stainless steel. Due to the extremely high temperature of the magnesium slag discharged from the calcining furnace, metal slag discharge structures cannot withstand such high temperatures. Therefore, these structures are prone to deformation due to thermal fatigue, and severe deformation renders them unusable, resulting in significant losses and increased production costs. Summary of the Invention
[0004] In view of the technical problem described in the background art above, the slag discharge structure of the prior art used for discharging magnesium slag is prone to deformation due to thermal fatigue. In order to address this technical problem, the present invention proposes a magnesium slag discharge and conveying device.
[0005] This invention features an inner lining layer between the metal box and the slag discharge hopper. The inner lining layer prevents the high-temperature magnesium slag from directly contacting the metal box, thus providing insulation. In addition, the inner lining layer also supports and stabilizes the metal box. Through the insulation, support, and stabilization functions of the inner lining layer, deformation of the metal box due to thermal fatigue can be better prevented, reducing the wear and tear of the metal box and thereby reducing production costs.
[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0007] A magnesium slag discharge and conveying device includes a conveying vehicle and a slag discharge structure. The slag discharge structure includes a frame, a slag discharge hopper, an inner lining, and a metal box. The metal box is located inside the frame and is fixedly connected to the frame. The slag discharge hopper is located inside the metal box and is used to contain magnesium slag. The inner lining is located between the metal box and the slag discharge hopper. The frame is located above the conveying vehicle.
[0008] Furthermore, the thickness of the inner lining layer is at least twice the thickness of the metal casing.
[0009] Further specifying, the slag discharge structure also includes a ventilation and heat dissipation pipe, which is located in the middle of the slag discharge hopper and is arranged along the length or width of the slag discharge hopper; the ventilation and heat dissipation pipe passes through the metal box, the inner lining layer and the slag discharge hopper, and its two ends are fixedly connected to the opposite sides of the frame body.
[0010] Further specified, multiple ventilation and heat dissipation pipes are arranged in parallel along the length or width of the slag discharge hopper.
[0011] Furthermore, the frame body is provided with perforated reinforcing ribs near the ventilation and heat dissipation pipes.
[0012] Furthermore, the top of the frame body is provided with frame lifting lugs.
[0013] Further specified, the top of the slag discharge hopper is provided with a feed inlet, and a slag hopper cover is detachably connected to the top of the frame body, the slag hopper cover being located above the feed inlet.
[0014] Furthermore, the slag hopper cover is provided with a cover lifting lug on its upper part.
[0015] Further defined, the conveyor vehicle includes a conveyor vehicle and a conveyor track, the conveyor vehicle is located above the conveyor track and is capable of rolling along the conveyor track; the frame body is located above the conveyor vehicle.
[0016] Further specifying, the inner lining layer is a ceramic layer or a concrete layer.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. This utility model discloses a magnesium slag discharge and conveying device, which provides an inner lining between the metal box and the slag discharge hopper. The inner lining can prevent the high-temperature magnesium slag from directly contacting the metal box, thus providing heat insulation. In addition, the inner lining also provides support and fixation for the metal box. Through the heat insulation, support and fixation functions of the inner lining, the deformation of the metal box due to thermal fatigue can be better prevented, reducing the wear of the metal box and thus reducing production costs.
[0019] 2. This utility model has a ventilation and heat dissipation pipe in the middle of the slag discharge hopper. The ventilation and heat dissipation pipe can better dissipate heat from the magnesium slag accumulated in the middle of the slag discharge hopper, thereby improving the heat dissipation effect of the magnesium slag and further preventing the heat of the magnesium slag from being too concentrated in the metal box, which could cause the metal box to deform.

Detailed Implementation
[0032] The technical solution of this utility model will be further explained and described below with reference to the accompanying drawings and specific embodiments, but this utility model is not limited to the embodiments described below.
[0033] See Figure 2 , Figure 3 and Figure 4 This utility model discloses a magnesium slag discharge and conveying device, comprising a conveying vehicle and a slag discharge structure. The slag discharge structure includes a frame body 101, a slag discharge hopper 104, an inner lining layer 106, and a metal box 108. The metal box 108 is located inside the frame body 101 and is fixedly connected to the frame body 101. The slag discharge hopper 104 is located inside the metal box 108 and is used to contain magnesium slag 107. The inner lining layer 106 is located between the metal box 108 and the slag discharge hopper 104. The frame body 101 is located above the conveying vehicle. Specifically, the slag discharge hopper 104 is a bucket-shaped structure formed by the metal box 108 and the inner lining layer 106. The frame body 101 is a frame structure formed by multiple transverse and longitudinal support rods. The metal box 108 is fixedly connected to the frame body 101 by welding, and the inner lining layer 106 can be fixedly connected to the metal box 108 by adhesive bonding. In this invention, the inner lining layer 106 can prevent the high-temperature magnesium slag from directly contacting the metal box 108, thus providing heat insulation. In addition, the inner lining layer 106 also provides support and fixation for the metal box 108. Through the heat insulation, support and fixation functions of the inner lining layer 106, the deformation of the metal box 108 due to thermal fatigue can be better prevented, reducing the wear and tear of the metal box 108 and thus reducing production costs.
[0034] In this invention, the thickness of the inner lining layer 106 is at least twice the thickness of the metal casing 108. As a preferred embodiment of this invention, considering the effects of heat insulation, support, and solidity, as well as cost, it is advisable that the thickness of the inner lining layer 106 is 2-3 times the thickness of the metal casing 108.
[0035] In this invention, the inner lining layer 106 is a ceramic layer or a concrete layer. To reduce costs, as a preferred embodiment of this invention, the inner lining layer 106 is a concrete layer.
[0036] In this invention, the slag discharge structure also includes a ventilation and heat dissipation pipe 102. The ventilation and heat dissipation pipe 102 is located in the middle of the slag discharge hopper 104 and is arranged along the length or width direction of the slag discharge hopper 104. The ventilation and heat dissipation pipe 102 passes through the metal box 108, the inner lining layer 106, and the slag discharge hopper 104, and its two ends are fixedly connected to the opposite sides of the frame body 101. Preferably, multiple ventilation and heat dissipation pipes 102 are arranged side by side along the length or width direction of the slag discharge hopper 104. The ventilation and heat dissipation pipe 102 enables the magnesium slag 107 accumulated in the middle of the slag discharge hopper 104 to dissipate heat better, improving the heat dissipation effect of the magnesium slag 107, thereby further preventing the heat of the magnesium slag 107 from being excessively concentrated in the metal box 108, which could cause the metal box 108 to deform.
[0037] Since the width of the slag discharge hopper 104 is smaller than its length, it is more beneficial to set the ventilation and heat dissipation pipe 102 along the width direction of the slag discharge hopper 104 to dissipate heat from the middle position of the slag discharge hopper 104. Therefore, as a preferred embodiment of the present invention, the ventilation and heat dissipation pipe 102 is set along the width direction of the slag discharge hopper 104.
[0038] The number of ventilation and heat dissipation pipes 102 is set according to the heat dissipation requirements. It can be 2, 3, 4 or 5. As a preferred embodiment of this utility model, 3 ventilation and heat dissipation pipes 102 are evenly arranged along the width direction of the slag discharge hopper 104.
[0039] Preferably, the present invention provides a perforated reinforcing rib 103 on the frame 101 near the ventilation and heat dissipation pipe 102. Each ventilation and heat dissipation pipe 102 is provided with two perforated reinforcing ribs 103. The two perforated reinforcing ribs 103 are respectively located near the two ends of the ventilation and heat dissipation pipe 102. The perforated reinforcing ribs 103 reinforce the position of the frame 101 near the ventilation and heat dissipation pipe 102, thereby improving the strength of that position.
[0040] Preferably, the present invention provides a frame lifting lug 105 on the top of the frame body 101. The purpose of providing the frame lifting lug 105 is to facilitate the placement of the entire slag discharge structure 1 on the conveyor vehicle 2 or the removal of it from the conveyor vehicle 2 by a crane.
[0041] This utility model has a feed inlet at the top of the slag discharge hopper 104, and a slag hopper cover 4 is detachably connected to the top of the frame body 101. The slag hopper cover 4 is located above the feed inlet. The slag hopper cover 4 can prevent the magnesium slag 107 from being scattered at the feed inlet, thereby playing a role in protecting the environment.
[0042] See Figure 5The present invention provides a cover lifting lug 401 above the slag hopper cover 4, which allows the crane to easily place the slag hopper cover 4 above the frame body 101 or move it down from above the frame body 101.
[0043] See Figure 1 and Figure 6 In this utility model, the conveyor vehicle includes a conveyor 2 and a conveyor track 3. The conveyor 2 is located above the conveyor track 3 and can roll along the conveyor track 3. The frame body 101 is located above the conveyor 2. Specifically, the conveyor 2 includes a drive motor 201, a first rolling wheel 202, a second rolling wheel 203, and a vehicle frame 204. In order to improve the stability of the movement of the conveyor 2, a drive motor 201, a first rolling wheel 202, and a second rolling wheel 203 are provided on opposite sides of the vehicle frame 204. The first rolling wheel 202 and the second rolling wheel 203 are both connected to the frame body 101 through bearings, so that the first rolling wheel 202 and the second rolling wheel 203 can roll on the conveyor track 3. The drive motor 201 is fixedly connected to the vehicle frame 204, and the output end of the drive motor 201 is connected to the first rolling wheel 202, that is, the first rolling wheel 202 is the drive wheel.
[0044] The two ends of the conveying track 3 are equipped with stop components, which are stop bars or baffles set at both ends of the conveying track 3. The stop components can effectively prevent the conveying vehicle 2 from slipping off the conveying track 3 and causing the slag discharge hopper 104 to tip over.
[0045] See Figure 1 This utility model features an opening on one side of the slag discharge structure (the right side in the figure), where a discharge gate is installed. The discharge gate consists of a metal layer (made of the same material as the metal housing 108) and an inner lining layer 106 located inside the metal layer. The top of the discharge gate is hinged to the frame 101, and the bottom or side of the discharge gate is connected to the frame 101 via a snap-locking structure. The snap-locking structure facilitates the opening and closing of the discharge gate. The snap-locking structure is existing technology; for specific reference, see the locking structure of the doors of dump trucks or freight trucks.
[0046] When it is necessary to dump the magnesium slag 107 inside the slag discharge hopper 104, open the discharge door and use a jack to lift the frame 101 as a whole on the other side of the bottom of the frame 101 (the side opposite to the discharge door). At this time, the jack is fixed on the vehicle frame 204 or the ground, so that the magnesium slag 107 can be dumped out. For details, refer to the self-unloading structure of the dump truck.
[0047] In this utility model, the length of the slag discharge structure is 4.35 meters, the width is 2.25 meters, and the height is 1.8 meters.
[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
