Description

Technical Field

[0001] This utility model relates to the field of slag discharge valve technology, and more specifically, to a special valve for slag discharge. Background Technology

[0002] Slag discharge valves are widely used in chemical, metallurgical, mining, and sewage treatment industries. They are key equipment in slag discharge systems for controlling the on / off flow of waste slag, and their performance directly affects the operating efficiency and stability of the entire slag discharge system. In existing technologies, conventional slag discharge valves often employ a straight cylindrical structure for their valve flow channels. During transportation, waste residue tends to accumulate at the connection between the flow channel and the connecting passage, especially when the waste residue contains lumpy or sticky materials. This accumulation is even more severe, leading not only to poor slag discharge but also increasing fluid resistance within the flow channel and raising energy consumption. Furthermore, the switching components of existing slag discharge valves only provide simple on / off control, failing to effectively clean waste residue adhering to the flow channel outlet (small end). Over time, the accumulation of waste residue degrades the valve's on / off sealing performance, and may even result in problems such as the valve failing to close tightly or becoming stuck. Furthermore, while some existing slag discharge valves incorporate scraping mechanisms for waste removal, the scraping components are often independently designed, requiring additional drive units to perform the scraping action. This not only increases the overall structural complexity of the valve and raises manufacturing costs, but also leads to low precision in the coordination between the scraping and switching components due to the difficulty in coordinating the control of multiple drive units, resulting in poor scraping performance. Additionally, the extra drive components occupy more installation space, limiting the valve's application in confined spaces. In summary, existing slag discharge valves suffer from low slag discharge efficiency, poor waste removal effect, and complex structure, making it difficult to meet the industrial sector's demands for efficient, stable, and compact slag discharge valves. Utility Model Content

[0003] Therefore, in order to solve the problems of low slag discharge efficiency and poor waste residue cleaning effect of traditional equipment, this utility model provides a special valve for slag discharge, the specific technical solution of which is as follows: A special valve for slag discharge, including A valve, wherein the valve has a flow channel and a first channel, the flow channel is funnel-shaped, one end of the flow channel is a large opening end, the other end of the flow channel is a small opening end, the large opening end is connected to the outside, and the small opening end is connected to the first channel; A switch assembly is disposed on the valve and is used to control the connection state between the small port end and the first channel; A scraper assembly is disposed on the small end and is slidably connected to the moving end of the switch assembly.

[0004] The aforementioned slag discharge valve features a funnel-shaped flow channel. The larger end of the channel connects to the outside, while the smaller end connects to the first channel. This tapering flow channel structure guides the waste slag smoothly towards the smaller end, significantly reducing the probability of waste slag accumulation and fluid resistance compared to traditional straight-cylinder channels, thus greatly improving slag discharge efficiency. A scraper assembly located at the smaller end and slidably connected to the moving end of the switching assembly allows the switching assembly to control the connection between the smaller end and the first channel while simultaneously performing the scraping action through its own movement. This eliminates the need for an additional drive device for the scraper assembly, simplifying the overall valve structure and reducing the difficulty and cost of subsequent maintenance. The precisely positioned scraper assembly at the smaller end of the channel directly removes and cleans the waste slag adhering there, preventing accumulation and ensuring the valve's sealing performance during opening and closing. This reduces the risk of jamming or incomplete closure due to waste slag accumulation, improving the valve's operational reliability. This special slag discharge valve solves the problems of low slag discharge efficiency and poor waste residue cleaning effect of traditional equipment.

[0007] Furthermore, the sealing ring is sleeved on the mounting base, and the scraper ring is sleeved on the liner; the sealing ring is sealed to both the mounting base and the scraper ring; the scraper ring is slidably connected to the moving end of the switch assembly.

[0008] Furthermore, the switching assembly includes a gate and a drive block. The valve body is also provided with an opening for the gate to pass through back and forth, and the opening is connected to the first channel. The drive block is disposed on the valve body, and the output end of the drive block is connected to the gate. The drive block is used to drive the gate to repeatedly pass through the opening.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] In this utility model, "first" and "second" do not represent a specific quantity or order, but are merely used to distinguish names.

[0021] like Figures 1-3 As shown, a slag discharge valve according to one embodiment of the present invention includes a valve 1, a switch assembly 2, and a scraper assembly 3. The valve 1 has a flow channel 4 and a first channel 5. The flow channel 4 is funnel-shaped, with one end being a large opening and the other end being a small opening. The large opening is connected to the outside, and the small opening is connected to the first channel 5. The switch assembly 2 is disposed on the valve 1 and is used to control the connection state between the small opening and the first channel 5. The scraper assembly 3 is disposed on the small opening and is slidably connected to the moving end of the switch assembly 2.

[0022] The aforementioned slag discharge valve features a funnel-shaped flow channel 4 within valve 1. The wider end of the flow channel 4 connects to the outside, while the narrower end connects to the first channel 5. This tapered flow channel 4 structure guides the waste slag smoothly towards the narrower end, significantly reducing the probability of waste slag accumulation within the flow channel 4 compared to a traditional straight-cylinder flow channel 4, thus decreasing fluid resistance and significantly improving slag discharge efficiency. Furthermore, the scraper assembly 3, located at the narrower end and slidably connected to the moving end of the switch assembly 2, allows the switch assembly 2 to simultaneously control the connection between the narrower end and the first channel 5. The scraping action is completed by the self-movement of the switching component 2, eliminating the need for an additional drive device for the scraping component 3. This simplifies the overall structure of the valve 1 and reduces the difficulty and cost of subsequent maintenance. The scraping component 3 is precisely positioned at the small end of the flow channel 4, enabling direct scraping and cleaning of the waste residue adhering to the small end. This avoids the accumulation of waste residue at the small end, which could affect the control of the switching component 2 over the connection state. This effectively ensures the sealing performance of the valve 1 during opening and closing, reduces the risk of the valve 1 becoming stuck or unable to close tightly due to waste residue accumulation, and improves the reliability of the valve 1's operation. This dedicated slag discharge valve solves the problems of low slag discharge efficiency and poor waste residue cleaning effect in traditional equipment.

[0023] like Figures 1-3As shown, in one embodiment, the valve 1 includes a valve body 11 and a liner 12 inserted into the valve body 11; the first channel 5 is disposed within the valve body 11; the flow channel 4 is disposed within the liner 12; the scraper assembly 3 is sleeved on the liner 12; the scraper assembly 3 includes a scraper ring 31, a mounting base 32, an elastic element 33, and a sealing ring 34; the mounting base 32 is disposed on the liner 12 and slidably connected to the liner 12, the mounting base 32 has a mounting hole, the elastic element 33 is inserted into the mounting hole, one end of the elastic element 33 is connected to the mounting base 32, and the other end of the elastic element 33 is connected to the liner 12; the sealing ring 34 is sleeved on the mounting base 32, and the scraper ring 31 is sleeved on the liner 12; the sealing ring 34 is sealed to both the mounting base 32 and the scraper ring 31; the scraper ring 31 is slidably connected to the moving end of the switch assembly 2. Thus, with the flow channel 4 located inside the liner 12 and the liner 12 inserted into the valve body 11, when the flow channel 4 is damaged due to waste residue wear, only the liner 12 needs to be replaced, without the need to replace the entire valve body 11, reducing the maintenance cost and replacement difficulty of the equipment; the mounting base 32 is connected to the liner 12 through the elastic element 33, and the elasticity of the elastic element 33 ensures that the scraping assembly 3 is always in close contact with the liner 12 (the small opening end of the flow channel 4), compensating for the gap caused by the wear of the parts and ensuring the stability of the scraping effect; the sealing ring 34 is sealed to the mounting base 32 and the scraping ring 31 respectively, which can prevent waste residue from entering the sliding gap between the mounting base 32 and the liner 12, avoiding the jamming of parts or aggravated wear, while reducing the risk of fluid leakage and further improving the sealing performance of the valve 1; the scraping ring 31 is sleeved on the liner 12 and slidably connected to the moving end of the switch assembly 2, so that the scraping action and the on / off control action of the switch assembly 2 are synchronized, ensuring that the scraping timing matches the on / off state and improving the accuracy of scraping.

[0024] like Figures 1-2As shown, in one embodiment, the switching assembly 2 includes a gate 21 and a drive block 22. The valve body 11 is also provided with an opening for the gate 21 to pass through repeatedly, and the opening communicates with the first channel 5. The drive block 22 is disposed on the valve body 11, and the output end of the drive block 22 is connected to the gate 21. The drive block 22 is used to drive the gate 21 to repeatedly pass through the opening. The gate 21 and the drive block 22 cooperate to control the communication state of the first channel 5. The scraper ring 31 is slidably connected to the gate 21. The valve body 11 includes... The passage 111 and the power chamber 112 are connected. The first channel 5 is located inside the passage 111, and the opening is located on the passage 111. The power chamber 112 is located on the passage 111, and the opening is connected to the first channel 5 and the power chamber 112 respectively. The drive block 22 is located on the power chamber 112, and the output end of the drive block 22 is located inside the power chamber 112 and connected to the gate 21. A high-temperature resistant explosion-proof limit switch is provided inside the power chamber 112. The high-temperature resistant explosion-proof limit switch is used to detect the movement stroke of the output end of the drive block 22. Thus, the valve body 11 is divided into a through pipe 111 and a power chamber 112. The output end of the drive block 22 and the connection part between the gate 21 and the drive block 22 are located in the power chamber 112, which can prevent waste residue and fluid from leaking into the drive component area and avoid the drive block 22 from being corroded by waste residue or fluid. At the same time, the sealing setting of the power chamber 112 is suitable for harsh working conditions. The gate 21 controls the opening and closing of the first channel 5 through the reciprocating motion of the opening. The separate design of the through pipe 111 and the sealing chamber makes the movement path of the gate 21 more regular, reduces the interference of external factors on the movement of the gate 21, and improves the accuracy of the on / off control.

[0025] In one embodiment, the drive block 22 is a buffered hydraulic cylinder. Thus, by using a buffered hydraulic cylinder as the drive block 22, the impact of the gate 21 during start-up, stop-motion, or reversal can be buffered, making the gate 21 move more smoothly, reducing rigid collisions between components, extending the service life of the gate 21, drive block 22, and related connecting parts, and simultaneously reducing noise and vibration during valve 1 operation.

[0026] In one embodiment, a lower valve seat 6 is further provided in the first channel 5, and the lower valve seat 6 is slidably connected to the gate 21. Thus, the slidable connection between the lower valve seat 6 and the gate 21 provides guidance for the movement of the gate 21, ensuring that the gate 21 moves along a preset path and improving the accuracy of on / off control; on the other hand, it can share the frictional force during the movement of the gate 21, reducing direct wear between the gate 21 and the inner wall of the first channel 5, and extending the service life of the gate 21 and the valve body 11.

[0027] In one embodiment, the valve body 11 of the slag discharge valve is made of wear-resistant alloy steel. Thus, the wear-resistant alloy steel valve body 11 possesses excellent wear resistance, resisting the scouring and abrasion of waste slag during the slag discharge process, significantly extending the service life of the valve body 11, adapting to high-wear slag discharge conditions, reducing the frequency of valve body 11 replacement, and lowering equipment operating costs.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
