Description

Technical Field

[0001] This utility model belongs to the field of mixer technology, and in particular relates to a sealed unloading structure for a mixer. Background Technology

[0002] Mixers, as a common industrial mixing equipment, are widely used in various industries such as construction, chemical, and food processing to uniformly mix various materials. Among the various components of a mixer, the discharge device is one of the key components. Its main function is to smoothly and efficiently discharge the material in the mixing drum after mixing is completed, so that it can be used for subsequent production processes.

[0003] Currently, common mixer discharge devices mainly fall into two categories: traditional butterfly valves and mechanical sealing structures. However, these existing discharge devices have several drawbacks. Traditional butterfly valves suffer from significant wear when handling wet materials containing aggregates, and their sealing performance rapidly declines after a period of use, leading to frequent leakage. Mechanical sealing structures, on the other hand, have poor reliability in sealing discharge when dealing with wet materials with large slurry volumes, making slurry leakage difficult to avoid. These problems not only affect the normal operation and production efficiency of the mixer but may also lead to material waste and environmental pollution, increase production costs for enterprises, and limit the application of mixers in industries or material mixing and discharge scenarios with high sealing performance requirements. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, one aspect of this application proposes a sealed discharge structure for a mixer, comprising:

[0006] The first discharge plate has a first connecting port; the first connecting port is used to connect to the discharge port of the mixer.

[0007] The second unloading plate has a second connecting port; the second connecting port is vertically opposite to the first connecting port.

[0008] A valve plate is movably connected between the first discharge plate and the second discharge plate for horizontal movement; the valve plate is provided with a valve port.

[0009] A drive assembly is connected to a valve plate to move the valve plate between a first position and a second position. When the valve plate is in the first position, the first and second connecting ports are connected through a valve port. When the valve plate is in the second position, the valve plate blocks the connection between the first and second connecting ports.

[0010] The first sealing ring is provided between the first unloading plate and the valve plate, and between the second unloading plate and the valve plate; the vertical space where the movement trajectory of the valve port is located is the valve reference space, and the first sealing ring is provided around the periphery of the valve reference space.

[0011] In this technical solution, the structural design utilizes a pull-out valve plate to connect and disconnect the communication ports. The valve plate is stably supported by the unloading plate. In the second position, the valve plate blocks the connection between the ports, stably closing the unloading channel and supporting the material to be unloaded. In the first position, the main structure of the valve plate moves out of the vertical space of the communication port, allowing for smooth material unloading. Furthermore, the unloaded material does not come into close contact with the valve plate as it passes through, thus reducing wear. On the other hand, during material unloading, the first sealing ring is located on the periphery of the material, preventing contact and wear. The first sealing ring also covers the movement range of the valve port, enhancing sealing performance and improving the overall sealing and reliability of the unloading device.

[0012] In some embodiments, it further includes:

[0013] The second sealing ring is provided between the first unloading plate and the valve plate, and between the second unloading plate and the valve plate; the vertical space where the first connecting port is located is the first reference space, the vertical space of the second connecting port is the second reference space, and the second sealing ring is arranged around the periphery of the first reference space and the second reference space.

[0014] In the technical solution, the structural design further improves the sealing performance around the connection port, effectively preventing material leakage from the connection port under high pressure or high viscosity conditions, improving the sealing performance of the unloading device under harsh working conditions, and further expanding the application range of the mixer.

[0015] In some embodiments, the first unloading plate is connected to the second unloading plate by fixing bolts; the valve plate is provided with fixing bolts on both sides in the horizontal direction.

[0016] In the technical solution, the structural design makes the unloading device more robust and stable to assemble, and the valve plate can be stably and movably installed between the unloading plates.

[0017] In some embodiments, the upper surface of the valve plate is attached to the lower surface of the first discharge plate, and the lower surface of the valve plate is attached to the upper surface of the second discharge plate.

[0018] In the technical solution, the structural design ensures that the valve plate and the unloading plate are in close contact. This not only improves the smoothness of the valve plate's horizontal movement but also enhances the sealing effect, reduces local wear, extends the service life of the valve plate and the unloading plate, and ensures the long-term stable operation of the unloading device.

[0019] In some embodiments, a first sliding groove is formed on the lower surface of the first unloading plate, and a second sliding groove is formed on the upper surface of the second unloading plate; the upper and lower parts of the valve plate are respectively disposed in the first sliding groove and the second sliding groove, so that the lower surface of the first unloading plate is attached to the upper surface of the second unloading plate.

[0020] In the technical solution, the structural design facilitates the installation and positioning of the valve plate through the sliding groove, and restricts the movement trajectory of the valve plate, making its horizontal movement smooth and stable, avoiding deviation and jamming, and improving the working accuracy and reliability of the unloading device; on the other hand, it allows the unloading plates to fit together, and the valve plate and the unloading plate can overlap to a certain extent, reducing the overall thickness of the unloading device.

[0021] In some embodiments, the first connecting port, the second connecting port, and the valve port have the same shape and size; when the valve plate is in the first position, the first connecting port, the second connecting port, and the valve port are aligned with the same vertical space.

[0022] In the technical solution, the structural design ensures smooth material flow when the connecting ports are connected, reduces flow resistance and eddy currents, and improves unloading efficiency; on the other hand, the same shape and size facilitate processing and manufacturing, reduce production costs, and improve production efficiency.

[0023] In some embodiments, the first connecting port, the second connecting port, and the valve port are circular with the same inner diameter; when the valve plate is in the first position, the first connecting port, the second connecting port, and the valve port are aligned with the same vertical axis.

[0024] In the technical solution, the circular connecting port and valve port in this structural design have better flow characteristics and structural strength, ensuring that when the connecting ports are connected, the material flow is uniform and continuous, avoiding material accumulation or poor unloading caused by irregular shapes, and further improving the performance and reliability of the unloading device.

[0025] In some embodiments, the driving component includes:

[0026] Tailstock, the tailstock is disposed on the first discharge plate and / or the second discharge plate;

[0027] A plate base is provided at one end of the valve plate;

[0028] The push-pull rod connects the tailstock and the plate seat respectively; the push-pull rod is used to move the plate seat horizontally by changing its own length, so as to drive the valve plate to move horizontally.

[0029] In the technical solution, the structural design enables the unloading port to be opened and closed quickly and reliably, meeting the unloading needs of different working conditions.

[0030] In some embodiments, the valve plate is provided with push-pull rods on both sides in the horizontal direction, and the push-pull rods are horizontally arranged.

[0031] In the technical solution, the structural design ensures that the valve plate is subjected to uniform force when it moves, avoiding the tilting and jamming problems caused by unilateral force, and improving the smoothness and accuracy of movement; on the other hand, the horizontal push-pull rod facilitates installation and layout, reduces space occupation, and makes the unloading device structure compact and reasonable.

[0032] In some embodiments, an upwardly extending upper discharge pipe is connected to the first communication port, the upper discharge pipe being used to connect to the discharge port; and a downwardly extending lower discharge pipe is connected to the second communication port.

[0033] In the technical solution, the structural design effectively connects the unloading device with the mixer's discharge port and other pipeline systems to ensure that the material is smoothly discharged and transported to the designated location.

[0034] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0045] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0046] In the description of this utility model, it should be understood that the terms "center", "lateral", "longitudinal", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0047] The terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first," "second," or "third" may explicitly or implicitly include one or more of that feature.

[0048] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0049] It should be noted that the mixer 100 typically includes a mixing tank 101, an agitator, and a mixing motor 102. The agitator is located inside the mixing tank 101. The mixing motor 102 is mounted on the mixing tank 101 and located outside the internal space of the mixing tank 101. The agitator is connected to the mixing motor 102, causing the agitator to rotate inside the mixing tank 101 under the drive of the mixing motor 102, agitating the materials inside the mixing tank 101, thereby mixing the materials evenly. The mixing tank 101 is typically provided with a feed inlet and a discharge outlet 103, so that materials can be fed into the mixing tank 101 through the feed inlet or discharged from the mixing tank 101 through the discharge outlet 103.

[0050] like Figures 1 to 7 As shown in an illustrative embodiment of the sealed discharge structure of the mixer of this utility model, the sealed discharge structure of the mixer includes a first discharge plate 200. The first discharge plate 200 is generally arranged horizontally, and a first connecting port 201 is provided on the first discharge plate 200, such that the first connecting port 201 vertically penetrates the first discharge plate 200. The first connecting port 201 is connected to the discharge port 103 of the mixer 100.

[0051] The sealed discharge structure of the mixer also includes a second discharge plate 300. The second discharge plate 300 is typically horizontally positioned and has a second connecting port 301 that vertically extends through it. The second connecting port 301 is vertically aligned with the first connecting port 201, ensuring the two ports are vertically aligned. The second connecting port 301 is typically aligned with or connected to a transfer device or container below it for receiving the discharged material.

[0052] The sealed discharge structure of the mixer also includes a valve plate 400. The valve plate 400 is movably connected between the first discharge plate 200 and the second discharge plate 300, allowing the valve plate 400 to move horizontally between the two discharge plates. The valve plate 400 is usually horizontally positioned, and a valve port 401 is provided on the valve plate 400, with the valve port 401 vertically penetrating the valve plate 400.

[0053] The sealed discharge structure of the mixer also includes a drive assembly 500. The drive assembly 500 is connected to the valve plate 400, causing the drive assembly 500 to move the valve plate 400 between a first position and a second position. When the valve plate 400 is in the first position, the valve port 401 on the valve plate 400 is simultaneously aligned vertically with the first connecting port 201 and the second connecting port 301, so that the first connecting port 201 and the second connecting port 301 are connected through the valve port 401. At this time, the material in the mixing tank 101 can be discharged sequentially through the discharge port 103, the first connecting port 201, the valve port 401, and the second connecting port 301, thus realizing the opening of the discharge structure. When the valve plate 400 is in the second position, the valve port 401 on the valve plate 400 moves horizontally to one side of the vertical space where the first connecting port 201 and the second connecting port 301 are located. The valve plate 400 separates the first connecting port 201 and the second connecting port 301, blocking the communication between the first connecting port 201 and the second connecting port 301. The material is blocked by the valve plate 400 in the first connecting port 201 and in the mixing tank 101 above the first connecting port 201, thereby closing the unloading structure.

[0054] Furthermore, by adjusting the position of the valve plate 400 in the horizontal direction, the area of ​​the valve port 401 that is aligned with the vertical space of the first connecting port 201 and the second connecting port 301 in the horizontal direction can be changed, thereby adjusting the opening degree of the unloading device.

[0055] The sealed discharge structure of the mixer also includes a first sealing ring 600. First sealing rings 600 are provided between the first discharge plate 200 and the valve plate 400, and between the second discharge plate 300 and the valve plate 400, respectively, to seal the gaps between the first discharge plate 200 and the valve plate 400, and between the second discharge plate 300 and the valve plate 400. When the valve plate 400 moves horizontally, the two first sealing rings 600 slide on the upper and lower surfaces of the valve plate 400, respectively. The first sealing rings 600 are typically positioned in the mounting groove 700 of the discharge plate to maintain a stable installation position.

[0056] The vertical space where the movement trajectory of the valve port 401 is located is taken as the valve reference space. Both first sealing rings 600 are arranged around the outer periphery of the valve reference space, so that when the valve port 401 moves between the first position and the second position, it is always in the vertical space inside the first sealing ring 600.

[0057] This structural design utilizes a horizontally pull-out valve plate 400 to connect and block the communication ports, thereby enabling the opening and closing of the unloading structure. Two unloading plates, one above the other, stably support the valve plate 400. When the unloading structure is closed, the valve plate 400 stably seals between the communication ports, providing stable support for the material to be unloaded. When the unloading structure is open, part or all of the valve plate 400 overflows the vertical space of the communication port, allowing the material to flow smoothly. As the unloaded material passes through the valve plate 400, it primarily contacts the edge of the valve port 401 and the valve plate 400 surrounding the valve port 401. The remaining portion of the valve plate 400 is hidden in the space between the unloading plates, reducing wear on the valve plate 400 caused by the material.

[0058] The arrangement of the first sealing ring 600 ensures that it covers the flow range during material discharge, guaranteeing a sealing effect. During material discharge, the material mainly flows vertically downwards through the valve port 401, with only a small portion entering the gap between the discharge plate and the valve plate 400. This prevents impact on the first sealing ring 600 located in this gap, ensuring its lifespan. On the other hand, the material within the valve port 401 moves with the valve plate 400 into the space between the two discharge plates. The two first sealing rings 600 are always positioned around the periphery of the vertical space where the valve port 401 is located, preventing this portion of material from leaking out through the gap between the discharge plate and the valve plate 400, ensuring a good and reliable sealing effect.

[0059] See Figures 4 to 5 In some embodiments, the sealed discharge structure of the mixer further includes a second sealing ring 800. Second sealing rings 800 are provided between the first discharge plate 200 and the valve plate 400, and between the second discharge plate 300 and the valve plate 400, respectively, to seal the gaps between the first discharge plate 200 and the valve plate 400, and between the second discharge plate 300 and the valve plate 400. When the valve plate 400 moves horizontally, the two second sealing rings 800 slide on the upper and lower surfaces of the valve plate 400, respectively. The second sealing rings 800 are typically disposed in the assembly groove 700 opened in the discharge plate to maintain a stable installation position.

[0060] The vertical space where the first connecting port 201 is located is the first reference space, and the vertical space where the second connecting port 301 is located is the second reference space. The second sealing ring 800 is arranged around the periphery of the first reference space and the second reference space, so that the first connecting port 201 and the second connecting port 301 are always in the vertical space inside the first sealing ring 600.

[0061] This structural design allows the two second sealing rings 800 to form sealing structures around the first connecting port 201 and the second connecting port 301, respectively, improving the sealing performance around the connecting ports. Furthermore, it forms a double seal with the first sealing ring 600, further enhancing the sealing effect of the unloading structure. This effectively prevents material from leaking from around the connecting ports under high pressure or high viscosity conditions, improves the sealing performance of the unloading device under harsh working conditions, and further expands the application range of the mixer 100.

[0062] See Figures 3 to 4 In some embodiments, the first discharge plate 200 is connected to the second discharge plate 300 by fixing bolts 900. Since the first discharge plate 200 is connected to the mixing tank 101 via the first connecting port 201 and the discharge port 103, the first discharge plate 200 is connected to the mixing tank 101, and the second discharge plate 300 is connected to the first discharge plate 200 via fixing bolts 900, ensuring stable vertical support for both the first and second discharge plates 200. The valve plate 400 has fixing bolts 900 on both sides in the horizontal direction, connecting the first discharge plate 200 and the second discharge plate 300 on both sides, thus confining the valve plate 400 between the fixing bolts 900 on both sides. This structural design makes the discharge device more secure and stable. Restricted by the fixing screws on both sides, the valve plate 400 can only move horizontally in one direction and will not dislodge from the space between the discharge plates in a direction perpendicular to the direction of movement of the valve plate 400, thus ensuring stable installation between the discharge plates.

[0063] See Figure 5 In some embodiments, the upper surface of the valve plate 400 is attached to the lower surface of the first unloading plate 200, and the lower surface of the valve plate 400 is attached to the upper surface of the second unloading plate 300. This structural design allows the valve plate 400 to be in close contact with the two unloading plates. The valve plate 400 can slide on the surface of the unloading plates during horizontal movement, improving the smoothness of its horizontal movement. It also restricts the direction of movement of the valve plate 400, improving its stability during movement, reducing localized wear, extending the service life of the valve plate 400 and the unloading plates, ensuring long-term stable operation of the unloading device, and the close contact also improves the sealing performance between the valve plate 400 and the unloading plates. Furthermore, the sealing ring is typically disposed in the assembly groove 700 of the unloading plate and is usually elastic, ensuring that the sealing ring not only does not obstruct the surface contact between the valve plate 400 and the unloading plates, but also flattens and tightens the valve plate 400 and the unloading plates when they are in contact, further improving the sealing effect of the sealing ring.

[0064] See Figures 6 to 7In some embodiments, a first sliding groove 202 is formed on the lower surface of the first unloading plate 200, and a second sliding groove 302 is formed on the upper surface of the second unloading plate 300. The upper and lower parts of the valve plate 400 are respectively disposed in the first sliding groove 202 and the second sliding groove 302, such that the lower surfaces of the first unloading plates 200 on both sides of the first sliding groove 202 are respectively attached to the upper surfaces of the second unloading plates 300 on both sides of the second sliding groove 302. This structural design facilitates the installation and positioning of the valve plate 400 through the sliding grooves, and restricts the movement trajectory of the valve plate 400, making its horizontal movement smooth and stable, avoiding deviation and jamming, and improving the working accuracy and reliability of the unloading device. In addition, the valve plate 400 is embedded in the two sliding grooves, preventing the surfaces of the two unloading plates from being separated by the valve plate 400, allowing the unloading plates to fit together tightly, improving the sealing performance, and reducing the vertical spatial tension of the two unloading plates, thus reducing the overall thickness of the unloading device.

[0065] See Figures 3 to 4 In some embodiments, the first connecting port 201, the second connecting port 301, and the valve port 401 are all identical in shape and size. This ensures that when the valve plate 400 is in the first position, the first connecting port 201, the second connecting port 301, and the valve port 401 are aligned in the same vertical space, forming a straight vertical line without any overlap. When the unloading structure is fully open, the first connecting port 201, the second connecting port 301, and the valve port 401 combine to form a vertical space with no horizontal fluctuations in its edges. This structural design allows the vertical space with flush edges to serve as a material discharge channel when the unloading structure is fully open, resulting in smooth material flow, low flow resistance, and no eddy currents, thus improving unloading efficiency. Furthermore, the identical shape and size allow the first connecting port 201, the second connecting port 301, and the valve port 401 to be stamped using the same mold, improving manufacturing convenience, reducing production costs, and eliminating the need to change molds for separate processing, thereby increasing production efficiency.

[0066] See Figures 3 to 4 In some embodiments, the first connecting port 201, the second connecting port 301, and the valve port 401 are circular with the same inner diameter. When the valve plate 400 is in the first position, the first connecting port 201, the second connecting port 301, and the valve port 401 are aligned with the same vertical axis, thus making the first connecting port 201, the second connecting port 301, and the valve port 401 coaxially arranged. In this structural design, the circular connecting ports and valve ports 401 have better flow characteristics and structural strength, ensuring uniform and continuous material flow when the connecting ports are connected, avoiding material accumulation or poor unloading caused by irregular shapes, and further improving the performance and reliability of the unloading device.

[0067] See Figures 2 to 4In some embodiments, the drive assembly 500 includes a tailstock 501, a plate base 502, and a push-pull rod 503. The tailstock 501 is disposed on the first unloading plate 200 and / or the second unloading plate 300, such that at least one of the first unloading plate 200 and the second unloading plate 300 is fixed to the tailstock 501. The plate base 502 is disposed at one end of the valve plate 400. The push-pull rod 503 connects the tailstock 501 and the plate base 502 respectively. By extending and shortening the plate base 502, the push-pull rod 503 drives the plate base 502 to move horizontally, thereby causing the plate base 502 to drive the valve plate 400 to move horizontally, realizing the opening and closing of the unloading structure. The push-pull rod 503 is typically an electric push rod, but a hydraulic rod can also be used. This structural design achieves the movement of the valve plate 400 through the pushing and pulling of the push-pull rod 503, thereby realizing the rapid and reliable opening and closing of the unloading mechanism. It has a simple structure, stable operation, and meets the unloading requirements of different working conditions.

[0068] See Figures 2 to 4 In some embodiments, the valve plate 400 is provided with push-pull rods 503 on both sides in the horizontal direction, so that the push-pull rods 503 on both sides can simultaneously push both ends of the plate seat 502, and both sides of the valve plate 400 can be fully driven. Since the valve plate 400 is usually horizontally set, the push-pull rods 503 are also horizontally set, so that both ends of the tail seat 501 and the plate seat 502 extend horizontally to the outside of the valve plate 400, and the push-pull rods 503 can also be positioned on the outside of the valve plate 400, so that the push-pull rods 503 and the valve plate 400 can be aligned horizontally. This structural design ensures that the valve plate 400 is subjected to uniform force on both sides when moving, avoiding tilting and jamming problems caused by unilateral force, and improving the smoothness and accuracy of movement. In addition, the horizontal setting of the push-pull rods 503 allows them to be horizontally aligned with the valve plate 400 at the same height, reducing the overall vertical space occupation of the unloading structure and making the unloading device structure more compact.

[0069] See Figures 1 to 2 , Figures 5 to 7 In some embodiments, an upwardly extending upper discharge pipe 203 is connected to the first connecting port 201, and the upper discharge pipe 203 is connected to the discharge port 103, so that the first discharge plate 200 and the bottom plate of the mixing tank 101 are spaced apart, so that there is sufficient space around the discharge plate to install the drive assembly 500. A downwardly extending lower discharge pipe 303 is connected to the second connecting port 301, and the lower discharge port 103 is connected to a transfer device or container for receiving the discharged material. This structural design effectively connects the discharge device with the discharge port 103 of the mixer 100 and other piping systems or containers, ensuring that the material is smoothly discharged and transported to the designated location.
