Abstract
Description
Technical Field
[0001] This utility model relates to a discharge valve, and more particularly to an intelligent discharge valve. Background Technology
[0002] As a switching device, discharge valves are widely used in material mixing fields. Most existing discharge valves are manual discharge valves, such as the manual discharge valve disclosed in publication number "CN221838921U", which includes a valve body with a valve cap on the top. The valve body has a valve stem connected to the valve cap at its top. The bottom end of the drive arm is hinged to the bottom end of the valve stem. When discharging, the operator drives the valve stem to rise through the drive arm, thereby opening the valve cap and realizing discharge.
[0003] Although this type of unloading valve has a relatively simple structure, the operator needs to manually operate the drive arm during operation. When the material in the hopper is heavy, the operator needs to use a lot of force to open the unloading valve. Moreover, after long-term use, the operator's labor intensity is also high. Therefore, it is necessary to design a pneumatic intelligent unloading valve that can be opened without manual intervention to reduce the operator's labor intensity and improve work efficiency. Summary of the Invention
[0004] To solve the above-mentioned technical problems, this utility model provides an intelligent unloading valve that can be opened and unloaded without manual operation, thereby reducing the labor intensity of operators and improving work efficiency.
[0005] The intelligent feeding valve of this utility model includes a valve body with a valve cap on the top. The intelligent feeding valve also includes a lifting assembly, which includes a chassis, a top plate located above the chassis, an air bladder located between the top plate and the chassis, and several support tubes whose inner cavity communicates with the air bladder. One end of the support tube is connected to the chassis, and the other end is connected to the valve body. A vibrator is provided on the surface of the top plate, and the output shaft of the vibrator is fixedly connected to the valve cap.
[0006] The advantages of this intelligent discharge valve lie in its lifting assembly, which includes an air bladder. A top plate and a bottom plate are located on the upper and lower sides of the air bladder, respectively. The bottom plate is connected to the valve body via a support pipe, and the top plate is connected to the valve cap via a vibrator. This lifting assembly allows the intelligent discharge valve to lift the valve cap using the air bladder and other components, thus opening and closing the valve cap. Compared to manual discharge valves, this valve uses an air bladder as the driving device, eliminating the need for manual operation and significantly reducing operator workload while increasing discharge efficiency. Furthermore, using air as the power source not only enables automatic lifting of the valve cap but also, compared to electric lifting devices, the air bladder, lacking electronic components, has a longer service life and does not contaminate the material during discharge.
[0007] Furthermore, in the intelligent feeding valve of this utility model, the air bladder is an annular air bladder, the chassis has a vertically arranged conduit, the top end of the conduit is fixed to the surface of the chassis, the top plate is provided with a guide rod, the top end of the guide rod is fixed to the top plate, and the bottom end of the guide rod is located in the inner cavity of the conduit.
[0008] The guide rod and guide tube are designed to allow components such as the top plate and valve cap to rise and fall vertically, preventing tilting during lifting and affecting unloading.
[0009] Furthermore, in the intelligent feeding valve of this utility model, a limiting tube is provided at the top of the conduit, the bottom end of the limiting tube is fixed to the top of the conduit, the top end of the limiting tube is located below the top plate, and the bottom end of the guide rod passes through the limiting tube and extends into the conduit, and is connected to the limiting block inside the conduit.
[0010] The setting of the limit tube and limit block realizes the upper and lower limits of the top plate and valve cap.
[0011] Furthermore, in the intelligent feeding valve of this utility model, the bottom end of the guide rod is a plurality of shuttle-shaped positioning elements connected in sequence, the middle part of the positioning element is thicker than the two ends of the positioning element, and the limiting block is sleeved on the outside of the positioning element, with the limiting block and the middle part of the positioning element having an interference fit.
[0012] The shuttle-shaped positioning element and the limiting block that is interference-fitted with the middle of the positioning element enable the limiting block to be positioned in the middle of the positioning element of the guide rod, thereby allowing the valve cap to be raised and lowered to a fixed height.
[0013] Furthermore, in the intelligent feeding valve of this utility model, the vibrator is a pneumatic vibrator.
[0014] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the following describes the embodiments of this utility model in detail.

[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.
[0020] Example 1: See Figure 1 The intelligent feeding valve of this embodiment includes a valve body 1, a valve cap 2 on the top of the valve body, and a lifting assembly. The lifting assembly includes a chassis 3, a top plate 4 located above the chassis, an air bladder 5 located between the top plate and the chassis, and several support tubes 6 whose inner cavity communicates with the air bladder. One end of the support tube is connected to the chassis, and the other end is connected to the valve body. A vibrator 7 is provided on the surface of the top plate, and the output shaft of the vibrator is fixedly connected to the valve cap.
[0021] This intelligent discharge valve incorporates a lifting assembly within its valve body. This assembly includes an air bladder, with a top plate and a bottom plate on its upper and lower sides respectively. The bottom plate is connected to the valve body via a support pipe, and the top plate is connected to the valve cap via a vibrator. This lifting assembly allows the intelligent discharge valve to lift the valve cap using the air bladder and other components, thus opening and closing the valve cap. Compared to manual discharge valves, this valve uses an air bladder as the driving device, eliminating the need for manual operation and significantly reducing operator workload while increasing discharge efficiency. Furthermore, the use of air power not only enables automatic valve cap lifting but also, compared to electric lifting devices, the air bladder, lacking electronic components, has a longer service life and does not contaminate the material during discharge.
[0022] The valve body is a tubular structure with openings at both ends. Its sidewalls can be slightly inclined to facilitate the pouring of materials. Flanges are provided at both ends for connection with external devices. A vent 8 is provided on its sidewall to communicate with the inner cavity of the support pipe for the input and output of external air sources.
[0023] The airbag can be an integrated waveguide-shaped airbag. To facilitate the installation of the guide rod, the airbag can be an annular airbag. In addition, several separate airbags connected to the corresponding support tubes can also be set to realize the lifting drive of the top plate and the installation of the guide rod.
[0024] The bottom of the airbag can be fixedly connected to the surface of the chassis, and the top of the airbag can be fixedly connected to the bottom of the top plate.
[0025] The aforementioned support tube provides support for components such as the chassis, airbag, and top plate. At the same time, it can connect to an external air source through the vent on the valve body surface and inflate or de-inflate the airbag through the vent on the chassis, thereby causing the airbag to expand or contract, which in turn drives the valve cap connected to it to rise and fall.
[0026] In order to enable the top plate and valve cap and other components to move vertically, the chassis has a vertically arranged guide tube 9, the top end of which is fixed to the surface of the chassis. The top plate is provided with a guide rod 10, the top end of which is fixed to the top plate, and the bottom end of which passes through the chassis and is located in the inner cavity of the guide tube.
[0027] During lifting and lowering, the top plate, driven by the airbag, moves the valve cap and guide rod up and down. The bottom end of the guide rod moves up and down in the inner cavity of the guide tube, thereby guiding the guide rod and valve cap.
[0028] In order to achieve upper and lower limit of the top plate and valve cap, a limit tube 11 is provided at the top of the conduit. The bottom end of the limit tube is fixed to the top of the conduit, and the top end of the limit tube is located below the top plate. The bottom end of the guide rod passes through the limit tube and extends into the conduit, and is connected to the limit block 12 inside the conduit.
[0029] When rising, the guide rod rises under the action of the airbag until the bottom limit block contacts the limit tube. When falling, the guide rod falls under the action of the airbag until the bottom surface of the top plate contacts the top of the limit tube, thereby realizing the upper and lower limit functions of the top plate and valve cap.
[0030] To achieve cushioning, the aforementioned limiting tube can be made of a material with a certain degree of elasticity, such as rubber or plastic.
[0031] The aforementioned limiting block can be fixedly connected to the guide rod. In addition, in order to enable the valve cap to rise to a certain fixed height, the bottom end of the guide rod has several sequentially connected shuttle-shaped positioning parts 13. The diameter of the middle part of the positioning part is larger than that of the two ends of the positioning part. The aforementioned limiting block is fitted on the outside of the positioning part, and it is interference-fitted with the middle part of the positioning part, that is, its inner diameter is slightly smaller than the outer diameter of the middle part of the positioning part. In this way, when the guide rod is raised and lowered, the limiting block at its bottom end can rise and fall along the several positioning parts and be stuck in the middle part of the positioning part. When further raising and lowering is required, the system only needs to increase the air supply power of the air bag so that the limiting block can undergo a certain deformation under greater pressure and pass through the middle part of the positioning part, thereby enabling the valve cap to rise and fall a fixed distance.
[0032] The vibrator above the top plate provides support and vibration for the valve cap. In this embodiment, the vibrator is a pneumatic vibrator, with its bottom end fixedly connected to the top surface of the top plate and its output shaft fixedly connected to the top of the valve cap. When the airbag drives the valve cap to open, the vibrator vibrates the valve cap to facilitate rapid material feeding.
[0033] The valve cap is used to open or close the valve body. It is cone-shaped and its bottom end is located inside the opening at the top of the valve body. When the air bladder contracts, the bottom edge of the valve cap fits tightly against the inner wall of the valve body under the action of the air bladder. When unloading, the valve cap rises to a predetermined height under the action of the air bladder. At this time, there is an annular gap between the inner wall of the valve body and the bottom edge of the valve cap. The material can be output through this gap to the valve body and finally output from the valve body to the predetermined container.
[0034] Example 2: This example's intelligent feeding valve, based on the intelligent feeding valve in Example 1, adds the following technical details. For specifics, please refer to... Figures 2-3 In this embodiment, the intelligent feeding valve has a support component between the vibrator 7 and the valve cap 2 to strengthen the connection between the vibrator output shaft and the valve cap and prevent it from tilting.
[0035] Specifically, the support assembly includes a connecting ring 14, a support ring 15, and several support rods 16. The connecting ring is sleeved on the output shaft of the vibrator and can be fixedly connected to the output shaft of the vibrator. The support ring is located above the connecting ring, and the overall outer diameter of the support ring is larger than the overall outer diameter of the connecting ring. Several support rods are arranged between the connecting ring and the support ring, with one end of the support rod connected to the connecting ring and the other end connected to the support ring.
[0036] Because the material distribution may be uneven, the pressure of the material on the valve cap is also uneven. The valve cap is only supported by the top of the vibrator output shaft. The valve cap, which is subjected to uneven force, is prone to loosening between itself and the vibrator output shaft, resulting in tilting and thus affecting the feeding of materials.
[0037] Because the overall outer diameter of the support ring is large, the support rod connecting the support ring and the connecting ring is inclined. Preferably, the support rod is set perpendicular to the inner wall of the valve cap.
[0038] During connection, the connecting ring is placed on the outside of the vibrator output shaft, the support ring is located below the inner wall of the valve cap, and the support rod or support ring contacts the inner wall of the valve cap to support the valve cap. This prevents the valve cap from easily becoming loose or tilted from the vibrator output shaft when subjected to large pressure or uneven pressure distribution, thus ensuring normal material feeding.
[0039] To enable the connection between the support rod and the support ring and connecting ring, the two ends of the support rod have connection holes, and the support ring and connecting ring can be formed by connecting two hinged semi-circular rings.
[0040] During connection, the support ring passes through the connection hole at the top of the support rod, and the connecting ring passes through the connection hole at the bottom of the support rod, thereby connecting the support components.
