Description

Technical Field

[0001] This utility model relates to the field of self-unloading coal slag, specifically to a self-unloading coal slag box. Background Technology

[0002] In existing electrolytic production processes, slag treatment is a critical step. The current process involves loading slag from the electrolytic cell into slag boxes and transporting them to dedicated transport vehicles. These vehicles then transport the slag to the slag treatment plant. However, the slag boxes are unloaded manually. Furthermore, manual unloading cannot remove the slag embedded in the tanks, causing the equipment to fail to shut down properly during subsequent loading and unloading operations. This results in significant slag leakage and low work efficiency. To address this issue, the following improvements are proposed. Utility Model Content

[0003] The present invention aims to provide a self-unloading coal slag box to solve the problem of low slag unloading efficiency.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a self-unloading charcoal slag box, including a frame, a hopper on the frame, a discharge port at the bottom of the hopper, a discharge plate slidably disposed at the bottom of the hopper at the discharge port, a pneumatic device disposed on the frame at the discharge port, the pneumatic device being connected to the discharge plate and used to drive the discharge plate to open and close at the discharge port, a ash-cleaning device being disposed at the sliding connection between the discharge port and the discharge plate, the ash-cleaning device being used to discharge the charcoal slag at the discharge port, and the discharge plate being linked with the ash-cleaning device.

[0005] The beneficial effects of this solution are as follows: the pneumatic device is connected to the unloading plate, and the unloading plate can be directly controlled by the pneumatic device, thereby controlling the opening and closing of the unloading port and unloading the carbon slag in the hopper. The linkage design between the ash removal device and the unloading plate can automatically remove the carbon slag embedded in the gaps or grooves when the carbon slag box is unloading or after unloading and the device structure is restored, avoiding the jamming problem caused by the accumulation of carbon slag. This design significantly improves the reliability of the equipment, reduces the frequency of manual cleaning, avoids equipment failure, and at the same time, the linkage design simplifies the operation process and improves work efficiency.

[0006] Preferably, as an improvement, grooves are provided on both sides of the discharge port for the discharge plate to be embedded, and the dust removal device is set in the grooves.

[0007] The beneficial effects are as follows: by setting the chute, the unloading plate can be supported by embedding in the chute, which can not only meet the sliding connection between the unloading plate and the bottom of the hopper, but also ensure that the unloading plate can be supported while sliding. In addition, the function of the unloading port is to achieve sealing and unloading switching through the tight fit between the unloading plate and the chute. However, if dust or particulate residue accumulates in the chute, gaps will appear in the fit between the unloading plate and the chute, causing air leakage and material leakage problems.

[0008] With the built-in chute in the dust removal device, the inner wall of the chute and the mating surface of the unloading plate can be cleaned simultaneously during the reciprocating movement of the unloading plate. This prevents the accumulation of dust from forming an isolation layer and ensures that the unloading plate always keeps a tight fit with the chute, thereby improving the sealing accuracy of the unloading port from the source and reducing material waste and system energy loss.

[0009] The chute and the unloading plate are high-frequency friction components at the unloading port. If the dust contains hard particles, long-term accumulation will form an abrasive layer when the unloading plate moves, accelerating the wear of the inner wall of the chute, causing the chute gap to increase and the edge of the unloading plate to wear out, thus shortening the component replacement cycle.

[0010] After the dust removal device removes the accumulated dust in real time, it can eliminate the grinding effect of dust abrasive on the chute and unloading plate, reduce abnormal wear between components, and reduce equipment operation and maintenance costs; at the same time, it can prevent dust from accumulating and clumping in humid environments, further protecting the structural integrity of components.

[0011] Preferably, as an improvement, the pneumatic device includes a cylinder and a reversing valve mounted on the frame, the reversing valve being connected to the cylinder, and the cylinder piston rod being connected to the unloading plate.

[0012] The beneficial effects are as follows: As the core of pneumatic control, the reversing valve can quickly switch the airflow direction through external signals. When the reversing valve supplies air to the rodless chamber of the cylinder, the piston rod extends and pushes the unloading plate to close along the slide groove, thus sealing the unloading port. When the reversing valve supplies air to the rod chamber, the piston rod retracts and pulls the unloading plate to open, thus completing the material unloading. The entire switching process has a fast response speed and can accurately match the rhythm of unloading on demand in the production line, avoiding material accumulation or leakage.

[0013] The extension and retraction stroke of the cylinder piston rod is a fixed value, which can be customized according to the required opening range of the discharge port. It is perfectly matched with the movement stroke of the discharge plate. No additional limiting structure is required to ensure that the discharge plate reaches the preset position every time it opens and closes. When closed, it ensures a tight fit with the chute. When opened, it ensures the full opening of the material flow channel and prevents abnormal working conditions caused by stroke deviation.

[0014] The cylinder is directly fixed to the frame, eliminating the need for an additional independent support structure. Assembly can be completed using the existing space of the frame, avoiding spatial interference with components such as the unloading port chute and dust removal device. Meanwhile, the reversing valve is compact and can be installed near the cylinder or centrally arranged in the control box, simplifying the air pipe layout and reducing the overall space occupied by the device.

[0015] Preferably, as an improvement, the chutes on both sides of the bottom end of the discharge port are C-shaped and symmetrical. The ash removal device includes a block that is horizontally and elastically slidably connected in the chutes. The discharge plate is embedded in the chutes, and the discharge plate is vertically provided with a drive column. The drive column corresponds to the block. The side of the block that is close to the inside of the chutes is provided with an inclined surface. The inclined surface intersects with the movement trajectory of the drive column. The drive column is used to drive the block through the inclined surface to push out the carbon slag in the chutes.

[0016] The beneficial effects are as follows: the drive column moves horizontally in the chute synchronously with the unloading plate, and its movement trajectory intersects with the inclined surface of the block. When the unloading plate is opened or closed, the drive column will naturally contact the inclined surface and generate a horizontal thrust. The block action can be triggered without additional power, realizing the linkage between the unloading action and the ash cleaning action, and avoiding the ash from clumping due to not being cleaned in time.

[0017] The horizontally elastically connected abutment block is located inside the chute. After being pushed by the inclined surface of the drive column, it moves horizontally to the outside of the chute, directly pushing out the carbon slag accumulated in the chute, rather than just scraping the carbon slag to other areas. Furthermore, the symmetrical abutment blocks on both sides move synchronously, which can push the slag from both sides of the chute to the middle or the outside at the same time, ensuring that there is no slag residue at the bottom.

[0018] Preferably, as an improvement, the abutment is provided with grooves at both ends of the inclined surface, and the grooves are smoothly connected to the inclined surface. The grooves are used for the drive column to be embedded.

[0019] The beneficial effects are as follows: the groove provides a precise embedding position for the drive column, ensuring that the drive column can move accurately along the preset path when engaging with the stop block. This helps to ensure the stability and consistency of the ash removal action, so that the drive column can reliably interact with the stop block each time the unloading plate moves, thereby effectively pushing out the carbon slag in the chute.

[0020] Furthermore, by setting grooves at both ends of the inclined surface of the abutment block, when the unloading plate drives the drive column to move in the chute and contact the corresponding inclined surface, the drive column will first be embedded in the groove. At this time, the groove serves as a guide for the drive column. When the drive column disengages from the corresponding inclined surface, the drive column will slide out through the groove at the other end of the inclined surface. When the grooves at both ends of the inclined surface cooperate with the drive column, the drive block will vibrate. This vibration will be transmitted to the chute. Since the chute and the hopper are rigidly connected, the chute will transmit the vibration to the hopper, causing the side wall of the hopper to vibrate. This vibration will shake off the carbon residue stuck to the side wall of the hopper. This vibration will exist whether the unloading plate is closed or open.

[0021] Preferably, as an improvement, the drive column is rotatably connected to the unloading plate.

[0022] The beneficial effects are: the rotating connection of the drive column allows the drive column and the inclined surface of the stop block to contact and interact without being connected by friction, thereby reducing wear between the drive column and the stop block, ensuring the durability of the structure, and increasing the service life of the parts.

[0023] Preferably, as an improvement, the number of abutments in the chute is several, and the dust removal device also includes a baffle plate disposed on the side of the abutment plate away from the inclined surface. The length of the baffle plate is greater than the length of the abutment plate, and the sum of the lengths of the baffle plates is equal to the length of the chute.

[0024] The beneficial effects are as follows: by setting up a baffle, the main function of the baffle is to prevent carbon slag from entering the chute and to push out the carbon slag that falls into the chute, while the main function of the block is to drive the baffle to slide in the chute. Therefore, the length of the baffle is greater than the length of the block, which can reduce the number of block parts, save and simplify the device structure without reducing the practicality of the device, and also reduce costs.

[0025] Preferably, as an improvement, the two side chutes are composed of C-shaped troughs, which are fixedly set at the bottom of the hopper. Each trough includes an upper wing plate, a lower wing plate, and a web plate. The longitudinal thickness of the abutment and the baffle is the same and is less than the longitudinal thickness of the chutes. The top of the abutment is tangent to the upper wing plate and is slidably connected.

[0026] The beneficial effects are as follows: the longitudinal thickness of the abutment and the baffle is the same and both are less than the longitudinal thickness of the chute. The upper flange of the abutment and the chute are tangent, which can ensure the sealing between the abutment and the baffle and the chute, thereby reducing the amount of carbon slag entering the chute.

[0027] Preferably, as an improvement, a T-shaped block is provided at the top of the abutment, and a T-shaped groove is provided on the upper wing plate for the abutment to be inserted into, and a tension spring is connected between the T-shaped block and the T-shaped groove.

[0028] The beneficial effects are as follows: Because the longitudinal width of the abutment block is smaller than the longitudinal width of the chute, by setting a T-shaped block, which is embedded in the upper wing plate of the chute, it is possible to ensure that the abutment block is tangentially suspended to the upper wing plate, and also to ensure the sliding connection between the abutment block and the baffle and the chute. In addition, by setting a tension spring, when the unloading plate slides out of the chute, the tension spring pulls the T-shaped block to slide to the bottom of the chute, and the T-shaped block drives the abutment block to slide to the bottom of the chute. The abutment block drives the baffle to slide into the interior of the chute. This process is the unloading plate in the open state, and the carbon slag will fall into the chute during the falling process. When the unloading plate is closed, the drive column will drive the abutment block and the baffle to push outward in the chute through the inclined surface. At this time, the baffle will push out the carbon slag present in the chute, thereby ensuring that the friction between the unloading plate and the chute is reduced when the unloading plate is closed. This design can avoid the need for a sealing design between the chute and the unloading plate, while achieving the performance of a sealing mechanism. It can reduce cost investment in both design and production.

[0029] Preferably, as an improvement, the unloading plate can drive the vibrating hopper of the dust removal device. Attached Figure Description

Detailed Implementation

[0031] The following detailed description illustrates the specific implementation method: The reference numerals in the accompanying drawings include: frame 1, pneumatic device 11, cylinder 111, reversing valve 112, hopper 2, discharge port 21, discharge plate 22, drive column 221, dust removal device 3, stop block 31, inclined surface 311, groove 312, T-block 313, tension spring 3131, baffle 32, groove 4, upper wing plate 41, lower wing plate 42, web plate 43, and slide groove 44.

[0032] Example The basic implementation examples are as follows: Figures 1-9 As shown, Figures 1-3The self-unloading slag bin shown includes a frame 1, on which a hopper 2 is installed. The hopper 2 has an inlet at the top and a outlet 21 at the bottom. The cross-sectional area of ​​the inlet is larger than that of the outlet 21. In addition, the side wall of the hopper 2 between the inlet and the outlet 21 is inclined to facilitate material unloading. A guardrail is provided on the outer edge of the inlet of the frame 1 to prevent slag from splashing or personnel from falling accidentally when manually dumping slag into the hopper 2. A pneumatic device 11 is installed on the frame 1. The pneumatic device 11 includes a cylinder 111 installed on the frame 1 at the outlet 21 and a reversing valve 112 installed on the frame 1. The cylinder 111 and the reversing valve 112 are pneumatically connected. The reversing valve 112 is electrically connected to an external control system and is used to control the extension and retraction of the piston rod of the cylinder 111.

[0033] like Figures 4-7 As shown, troughs 4 are symmetrically welded to both sides of the bottom end of the hopper 2 at the discharge port 21. The cross-section of the trough 4 is C-shaped and includes an upper wing plate 41, a lower wing plate 42, and a web plate 43 perpendicular to the upper and lower wing plates 42. The upper wing plate 41 and the lower wing plate 42 are horizontally arranged. A C-shaped groove 44 is formed between the upper wing plate 41, the web plate 43, and the lower wing plate 42 of the trough 4. The grooves 44 of the troughs 4 on both sides of the discharge port 21 are arranged opposite to each other. A discharge plate 22 is slidably arranged at the bottom end of the hopper 2 at the discharge port 21. The two ends of the discharge plate 22 are slidably connected to the hopper 2 through the grooves 44. A dust removal device 3 is arranged in the grooves 44 of the trough 4. The dust removal device 3 includes a stop block 31 slidably connected in the grooves 44. The stop block 31 is horizontally slidably connected in the grooves 44 and its direction is perpendicular to the web plate 43. In addition, the dust removal device 3 also includes a fixing A baffle 32 is welded to the side of the abutment 31 away from the web plate 43. The longitudinal thickness of the abutment 31 and the baffle 32 is the same and both are less than the longitudinal thickness of the slide groove 44. A T-shaped block 313 is fixedly installed at the top of the abutment 31. The upper wing plate 41 has a T-shaped groove for the T-shaped block 313 to be inserted and slid. The abutment 31 and the baffle 32 are slidably connected in the slide groove 44 through the cooperation of the T-shaped block 313 and the T-shaped groove. A tension spring 3131 is connected between the T-shaped block 313 and the T-shaped groove. The top of the abutment 31 and the baffle 32 is tangent to the upper wing plate 41, which can ensure the sealing between the abutment 31 and the baffle 32 and the slide groove 44, thereby reducing the amount of carbon slag entering the slide groove 44. The cylinder body of the cylinder 111 is fixedly installed on the frame 1. A connecting rod is provided at the bottom of the unloading plate 22. The piston rod end of the cylinder 111 is bolted to the connecting rod.

[0034] like Figures 4-5As shown, there are several cleaning devices 3 in the chute 44, and the length of the baffle 32 along the direction of the chute 44 is greater than the length of the block 31 along the direction of the chute 44. The sum of the lengths of the baffles 32 is equal to the length of the chute 44. By setting the baffles 32, the main function of the baffles 32 is to prevent carbon slag from entering the chute 44 and to push out the carbon slag that falls into the chute 44. The main function of the block 31 is to drive the baffles 32 to slide in the chute 44. Therefore, the length of the baffles 32 is greater than the length of the block 31, which can reduce the number of parts of the block 31, save and simplify the device structure without reducing the practicality of the device, and also reduce the cost.

[0035] like Figures 4-9 As shown, the abutment 31 has an inclined surface 311 on the side near the web 43 of the groove 4. Grooves 312 are provided at both ends of the abutment 31 on the inclined surface 311. The grooves 312 are smoothly connected to the abutment 31 and the inclined surface 311. The bottom ends of the abutment 31 and the baffle 32 are flush and have a sliding gap with the lower flange 42 of the groove 4. Furthermore, there is also a sliding gap between the abutment 31 and the web 43 of the groove 4. Several drive columns 221 are symmetrically arranged on both sides of the unloading plate 22, and all drive columns 221 are rotatably connected. The unloading plate 22 and the drive column 221 are arranged in an L-shape. When the unloading plate 22 is embedded in the chute 44, the unloading plate 22 body and the drive column 221 are respectively embedded in the sliding gap between the ash cleaning device 3 and the lower wing plate 42 and the sliding gap between the inclined surface 311 and the web plate 43. The groove 312 is used for the drive column 221 to be embedded. The inclined surface 311 and the movement trajectory of the drive column 221 intersect. The drive column 221 is used to drive the abutment block 31 through the inclined surface 311 to push out the carbon slag in the chute 44.

[0036] The specific implementation process is as follows: The drive column 221 moves horizontally in the chute 44 synchronously with the unloading plate 22. Its movement trajectory intersects with the inclined surface 311 of the abutment block 31. When the unloading plate 22 is opened or closed, the drive column 221 will naturally contact the inclined surface 311 and generate a horizontal thrust. The abutment block 31 can be triggered without additional power, realizing the linkage between the unloading action and the ash cleaning action, and avoiding the ash from clumping due to not being cleaned in time. When the discharge plate 22 moves the drive column 221 within the chute 44 and contacts the corresponding inclined surface 311, the drive column 221 will first embed itself in the groove 312. At this time, the groove 312 serves as a guide for the drive column 221. When the drive column 221 disengages from the corresponding inclined surface 311, the drive column 221 will slide out through the groove 312 at the other end of the inclined surface 311. When the grooves 312 at both ends of the inclined surface 311 engage with the drive column 221, the drive block will vibrate. This vibration will be transmitted to the chute 44. Since the chute 44 and the hopper 2 are rigidly connected, the chute 44 will transmit the vibration to the hopper 2, causing the side wall of the hopper 2 to vibrate. This vibration will shake off the sticky carbon residue on the side wall of the hopper 2. This vibration will exist whether the discharge plate 22 is closed or open.

[0037] The longitudinal width of the abutment block 31 is smaller than the longitudinal width of the chute 44. By setting a T-shaped block 313, which is embedded in the upper wing plate 41 of the groove member 4, it is possible to ensure that the abutment block 31 is tangentially suspended from the upper wing plate 41, and also to ensure the sliding connection between the abutment block 31, the baffle 32, and the groove member 4. In addition, by setting a tension spring 3131, when the unloading plate 22 slides out of the chute 44, the tension spring 3131 pulls the T-shaped block 313 to slide towards the bottom of the chute 44, and the T-shaped block 313 drives the abutment block 31. As the material slides towards the bottom of the trough 44, the abutment 31 drives the baffle 32 to slide into the interior of the trough 44. This process is the opening state of the unloading plate 22. During the descent of the charcoal slag, it will fall into the trough 44. When the unloading plate 22 is closed, the drive column 221 will drive the abutment 31 and the baffle 32 to push outward in the trough 44 through the inclined surface 311. At this time, the baffle 32 will push out the charcoal slag present in the trough 44, thereby ensuring that the friction between the unloading plate 22 and the trough 44 is reduced when the unloading plate 22 is closed.
