Description

Technical Field

[0001] This utility model relates to the field of water slag bin technology, and more particularly to a water slag bin discharge structure. Background Technology

[0002] A slag silo is a container used to store slag, a granular waste residue formed after blast furnace slag has been rapidly cooled in water. It can be used as a binder in cement production. The slag silo facilitates the centralized storage and subsequent transportation of slag. When the slag in the silo needs to be transported, the valve at the bottom of the silo is opened, and the slag is discharged through the discharge pipe at the bottom of the silo onto a slag conveyor belt. The conveyor belt then transports the slag to the slag dump. In actual use, occasionally large-diameter slag gates are encountered, which is limited by the diameter of the existing discharge pipe and the conveying capacity of the slag conveyor belt. Based on the conventional design of water slag diameter, and with a fixed discharge pipe diameter, when the water slag diameter is larger than the discharge pipe diameter, the water slag cannot be discharged through the discharge pipe and accumulates at the junction of the discharge pipe and the water slag bin. At the same time, water slag of the conventional diameter cannot be discharged either. If the discharge pipe diameter is increased, although larger diameter water slag can be discharged from the water slag bin, the increased discharge pipe diameter will result in a larger amount of water slag discharged per unit time during normal use. This increased volume of water slag requires a sluice gate conveyor belt with a larger conveying capacity to meet the demand, thus increasing equipment costs. Utility Model Content

[0003] The purpose of this utility model is to provide a discharge structure for a slag bin, in order to solve the technical problem mentioned in the background art of how to ensure that slag with a large diameter can be discharged smoothly through the discharge pipe, while reducing the impact on the conveying equipment during normal use.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a water slag bin discharge structure, including a discharge pipe installed at the bottom of the water slag bin, a discharge channel connected to the water slag bin inside the discharge pipe, the diameter of the discharge channel being larger than the diameter of the water slag inside the water slag bin, a support rod being provided below the connection between the discharge pipe and the water slag bin, the support rod and the discharge pipe being pluggable and detachable; when the support rod is inserted into the discharge pipe, discharge ports are formed on both sides of the support rod.

[0005] Beneficial effects: When the baffle is horizontal in the discharge channel, the support rod is inserted into the discharge pipe and positioned directly below the baffle to support it. The weight of the slag accumulated on the baffle is distributed to the support rod and mounting shaft, thus forming a discharge port between the end of the baffle and the inner wall of the discharge pipe. The cross-sectional area of ​​the discharge port is smaller than that of the discharge channel. Due to the smaller cross-sectional area of ​​the discharge port, the amount of slag discharged per unit time is small, and the existing conveying capacity of the sluice gate conveyor belt can meet the transportation requirements. When large-diameter slag needs to enter the discharge channel... Pull out the support rod to make the baffle vertical, forming a discharge port between the side of the baffle and the inner wall of the discharge pipe. At this time, the cross-sectional area of ​​the discharge port is the same as the cross-sectional area of ​​the discharge channel, allowing large-diameter slag to smoothly enter the discharge channel. After the large-diameter slag enters the discharge channel, the baffle is restored to a horizontal state, and then the support rod is reinserted into the discharge pipe to support the baffle. Therefore, by setting up the baffle and support rod, large-diameter slag can be discharged from the sluice gate chamber without replacing the sluice gate conveyor belt, while also meeting the regular slag discharge requirements.

[0006] In a preferred embodiment of this application, two mounting posts are installed on the discharge pipe, and the two mounting posts are arranged opposite to each other on the discharge pipe. Each mounting post is provided with an insertion hole that is adapted to the support rod, and the support rod can be inserted and removed into the insertion hole.

[0007] The beneficial effect is that the support rod and the mounting column can be plugged in and removed by the interlocking hole. When the support rod is damaged, the old support rod can be pulled out and the new support rod can be inserted to complete the replacement. There is no need to perform destructive operations such as cutting or welding on the mounting column and the discharge pipe.

[0008] In a preferred embodiment of this application, slag discharge gates are symmetrically arranged on both sides of the discharge pipe, and the slag discharge gates are installed on the slag discharge gates. The slag discharge gates are driven to close and open at the bottom of the discharge pipe by the slag discharge gates.

[0009] The beneficial effect is that the symmetrical arrangement and synchronous operation of the two-sided actuators create a bidirectional balanced driving force on the slag discharge gate. Compared with single-sided drive, symmetrical drive can ensure that the slag discharge gate always moves along the preset trajectory during opening and closing, avoiding tilting and jamming of the slag discharge gate due to unilateral force.

[0010] In a preferred embodiment of this application, the execution component includes a mounting base installed on the outer wall of the discharge pipe, a connecting rod rotatably mounted on each mounting base, a slag discharge gate and a connecting rod fixedly connected, a driving component fixedly mounted on the slag discharge gate, a driving source installed between the driving component and the outer wall of the discharge pipe, the output end of the driving source and the driving component rotatably connected, and the driving source and the outer wall of the discharge pipe rotatably connected.

[0011] Beneficial effects: The mounting base in this solution is fixed on the outer wall of the discharge pipe, providing a stable support foundation for the entire execution component; the connecting rod is rotatably connected to the mounting base, and the slag discharge door is fixedly connected to the connecting rod. This structural design enables the slag discharge door to maintain a stable movement trajectory during opening and closing, ensuring the reliability and stability of the device.

[0012] In a preferred embodiment of this application, a receiving groove is provided inside the slag discharge gate. When the slag discharge gate is in the closed state, the discharge pipe is inserted into the receiving groove, the side wall of the receiving groove abuts against the side wall of the discharge pipe, and the bottom wall of the receiving groove is located directly below the discharge channel and abuts against the bottom of the discharge pipe.

[0013] Beneficial effects: When the slag discharge gate is closed, the side wall of the receiving tank abuts against the side wall of the discharge pipe, and the bottom wall abuts against the bottom of the discharge pipe. This effectively reduces the possibility of material leakage from the gap between the discharge pipe and the slag discharge gate when the gate is closed, improves the system's sealing performance, helps prevent dust from flying, improves the working environment, and also avoids material waste.

[0014] In addition to the technical problems solved by the present invention, the technical features constituting the technical solutions, and the advantages brought about by the technical features of these technical solutions as described above, other technical problems that the present invention can solve, other technical features contained in the technical solutions, and the advantages brought about by these technical features will be further described in detail with reference to the accompanying drawings.

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings.

[0018] Please see Figure 1As shown, the water slag bin discharge structure of this embodiment includes a discharge pipe 01 installed at the bottom of the water slag bin. A discharge channel 02, which is connected to the water slag bin, is provided inside the discharge pipe 01. Actuating components are symmetrically arranged on both sides of the discharge pipe 01, and discharge gates 05 are installed on the actuating components. The actuating components drive the discharge gates 05 to close and open at the bottom of the discharge pipe 01. When water slag in the water slag bin needs to be discharged, the actuating components drive the discharge gates 05 to open, and the water slag in the water slag bin is discharged from the discharge pipe 01.

[0019] The execution component includes multiple mounting seats 03 installed on the outer wall of the discharge pipe 01. In this embodiment, two mounting seats 03 are installed on the outer wall of the discharge pipe 01. A connecting rod 04 is rotatably mounted on each mounting seat 03. The slag discharge gate 05 is fixedly connected to the connecting rod 04 by fasteners. The mounting seat 03 includes a mounting plate installed on the outer wall of the discharge pipe. Two extension plates are fixedly mounted on the mounting plate by welding. Each extension plate has a connecting plate 15 extending towards the slag discharge gate 05 at its end. A mounting groove is provided between the two extension plates. A connecting shaft is provided in the mounting groove. The two ends of the connecting shaft are fixedly connected to the connecting plate 15 respectively. The connecting rod 04 is rotatably mounted on the connecting shaft, so that the connecting rod 04 can rotate vertically around the mounting seat, and the slag discharge gate 05 can also rotate vertically with the connecting rod 04.

[0020] A drive component 06 is fixedly installed on the slag discharge gate 05 by fasteners. A drive source 07 is installed between the drive component 06 and the outer wall of the discharge pipe 01. The drive source 07 is preferably a cylinder. The output end of the drive source 07 is rotatably connected to the drive component 06. The drive source 07 and the outer wall of the discharge pipe 01 are rotatably connected by a connecting seat. The drive component 06 includes a fixing plate fixedly installed on the slag discharge gate 05 by fasteners. A drive rod is fixedly installed on the end of the fixing plate near the discharge pipe 01 by welding. The drive rod and the fixing plate are arranged perpendicular to each other. An adapter rod is fixedly installed at the end of the drive rod. The drive component 06 is Z-shaped. The output end of the drive source 07 is rotatably connected to the adapter rod.

[0021] When the output end of the drive source 07 extends, the slag discharge gate 05 rotates around the mounting base 03, closing the slag discharge gate 05 at the bottom of the discharge pipe 01, preventing the water slag in the water slag bin from being discharged through the discharge channel 02. When the output end of the drive source 07 retracts, the slag discharge gate 05 rotates in the opposite direction around the mounting base 03, opening the slag discharge gate 05, and the water slag in the water slag bin is discharged through the discharge channel 02 to the outside of the discharge pipe 01.

[0022] An L-shaped receiving groove 08 is provided inside the slag discharge gate 05. The width of the receiving groove 08 is adapted to the shape of the discharge pipe 01. When the slag discharge gate 05 is in the closed state, the side wall of the receiving groove 08 abuts against the side wall of the discharge pipe 01. The bottom wall of the receiving groove 08 is located directly below the discharge channel 02 and abuts against the bottom of the discharge pipe 01, so that the discharge pipe 01 is inserted into the receiving groove 08.

[0023] In practical use, it was found that when the diameter of the slag in the slag bin is larger than the diameter of the discharge channel 02 in the discharge pipe 01, this slag cannot pass through the discharge pipe 01. To solve this problem, the diameter of the discharge channel 02 in the discharge pipe 01 was increased, making the diameter of the discharge channel 02 larger than the slag with the largest diameter in the slag bin, thus ensuring that the slag with the largest diameter in the slag bin can be discharged smoothly through the discharge channel 02. However, when the diameter of the discharge channel 02 is increased, the excessive amount of slag discharged will cause a high-intensity impact on the conveying equipment below the slag bin.

[0024] To address the issue of excessive slag discharge, a pluggable support rod 09 and a mounting shaft 13 rotatably mounted on the discharge pipe 01 are provided. The mounting shaft 13 is located near the inner wall of the discharge pipe and parallel to the support rod 09. A baffle 14 is fixedly mounted on the mounting shaft 13. The baffle 14 is installed inside the discharge pipe and located below the connection between the discharge pipe 01 and the slag bin. The support rod 09 is preferably made of threaded steel. A geared motor 16 is mounted outside the discharge pipe 01, and the output end of the geared motor 16 is connected to the mounting shaft 13 for transmission.

[0025] In normal use, the geared motor 16 drives the baffle 14 to rotate, so that the baffle 14 is in a horizontal state. Then, the support rod 09 is inserted into the discharge pipe 01 and positioned directly below the baffle 14 to support the baffle 14. At this time, the geared motor 16 can stop working. The weight of the water sludge accumulated on the baffle 14 is distributed to the support rod 09 and the mounting shaft 13 through the baffle 14, thereby forming a discharge port 10 between the end of the baffle 14 and the inner wall of the discharge pipe 01. The cross-sectional area of ​​the discharge port 10 is smaller than the cross-sectional area of ​​the discharge channel 02. A water gate of a normal diameter enters the discharge channel 02 through the discharge port 10.

[0026] When large-diameter slag needs to enter the discharge channel 02, the reduction motor 16 rotates in the forward direction, driving the mounting shaft 13 to rotate in the forward direction, causing the baffle 14 to rotate towards the slag bin, separating the support rod 09 from the baffle 14, making it easier for manual removal of the support rod 09 from the discharge pipe 01. After the support rod 09 is removed, the reduction motor 16 rotates in the reverse direction, making the baffle 14 vertical, forming a discharge port 10 between the side of the baffle 14 and the inner wall of the discharge pipe 01. At this time, the cross-sectional area of ​​the discharge port 10 is the same as that of the discharge channel 02, allowing the large-diameter slag to smoothly enter the discharge channel 02. After the large-diameter slag enters the discharge channel 02, the reduction motor 16 rotates in the forward direction, driving the baffle 14 back to a horizontal state, and then the support rod 09 is reinserted into the discharge pipe 01 to support the baffle 14.

[0027] Two mounting posts 11 are installed on the discharge pipe 01. The two mounting posts 11 are arranged opposite to each other on the discharge pipe 01. Each mounting post 11 is provided with an insertion hole 12 that is adapted to the support rod 09. The two insertion holes 12 are coaxially arranged, and the support rod 09 can be inserted and removed into the insertion hole 12.

[0028] If the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0029] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
