Description

Technical Field

[0001] The present application relates to the technical field of ternary material mixing, and in particular to a discharge valve assembly and a plowshare mixer. Background Art

[0002] The plow blade mixer is a highly efficient material mixing equipment that can solve the problems of agglomeration and clumping in the material mixing process. When the plow blade mixer is in use, the main shaft drives the plow blade to rotate, and the fly blade shaft drives the fly blade to rotate at high speed. The material in the cylinder is thrown up by the strong action of the plow blade. Part of the material moves in a circle along the cylinder wall, while the other part of the material is thrown to the center of the cylinder or scattered to the two ends of the cylinder along the normal direction of the plow blade wall, and the floating diffusion mixing is carried out. At the same time, when the material flows through the high-speed rotating fly blade, it is sheared and strongly diffused at high speed, and shearing diffusion mixing is carried out. Therefore, the movement trajectory of the material in the mixer is crisscrossed and collides with each other, generating strong vortexes, and achieving uniform mixing in a very short time.

[0003] In the related technical solutions, the discharge port of the plowshare mixer is generally arranged at the bottom of the machine, and the discharge port is also provided with a matching valve core, which can enter the discharge port to block the discharge port when in use to prevent material leakage. After the materials are mixed in the mixer, the valve core can be moved away from the discharge port to open the discharge port, thereby discharging the materials.

[0004] However, in the solutions of the related art, materials are easily adhered to the side of the valve core during use, so that after the valve core enters the discharge port, a gap is generated between the valve core and the discharge port, thereby causing leakage of materials and affecting the normal use of the product.

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments.

[0031] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0032] As described in the background technology, there may be a gap between the discharge port and the valve core of the plowshare mixer in the related technology solution, which may cause leakage of materials in the mixer and affect the normal use of the product. Research has found that the cause of the above problem is that after the material enters the mixer, it will accumulate at the discharge port under the action of gravity, and some of the material will adhere to the side of the valve core. When the valve core is opened, some of the material adhering to the side of the valve core will not fall off. After the valve core enters the discharge port again, a gap will appear between the part with the material adhering and the inner wall of the discharge port, causing leakage of the material.

[0033] In view of this, the embodiments of the present application aim to provide a discharge valve assembly and a plowshare mixer, by arranging a first air outlet connected to an air source on the first flange, and positioning the valve core below the first air outlet in the second state, so that in the second state, the first air outlet can be used to blow air to the valve core to remove material adhering to the surface of the valve core, thereby ensuring the sealing of the connection between the valve core and the discharge channel in the first state, reducing the risk of material leakage at the discharge port, and ensuring the normal use of the product.

[0034] The contents of the embodiments of the present application will be described in detail below in conjunction with the accompanying drawings so that those skilled in the art can understand the contents of the present application in more detail.

[0035] Figure 1 A bottom view of a discharge valve assembly provided in one embodiment of the present application; Figure 2 A side view of a discharge valve assembly provided in accordance with an embodiment of the present application.

[0036] Please refer to Figure 1-Figure 2 , this embodiment provides a discharge valve assembly, including:

[0037] The discharge channel 100 is located at the lower part of the mixer. The discharge channel 100 is generally cylindrical. Both ends of the discharge channel 100 are open for connecting the internal and external environments of the mixer respectively. A discharge port 110 is formed at one end of the discharge channel 100 .

[0038] The first flange 200 is sleeved on the discharge channel 100 and is located on one side of the discharge port 110. The first flange 200 and the discharge channel 100 can be integrally formed. The first flange 200 is provided with a first air outlet 210, which is used to connect to an air source. The air source may include, for example, a compressor, an air pump, and other equipment to supply air to the first air outlet 210.

[0039] The valve core 300 is detachably connected to the discharge channel 100, and the outer diameter of the valve core 300 is adapted to the inner diameter of the discharge channel 100. The valve core 300 of this embodiment has a first state and a second state relative to the discharge channel 100. In the first state, the valve core 300 enters the discharge channel 100 to block the discharge port 110. In the second state, the valve core 300 is away from the discharge port 110 to open the discharge port 110, thereby facilitating the flow of materials from the mixer; in the second state, the valve core 300 is located below the first air outlet 210, and the air source can be opened at this time, so that the first air outlet 210 blows air to the valve core 300 to remove the material 10 adhering to the valve core 300.

[0040] From the above description, it can be known that in this embodiment, a first air outlet 210 connected to an air source is provided on the first flange 200, and the valve core 300 is located below the first air outlet 210 in the second state, so that the first air outlet 210 can be used to blow air to the valve core 300 in the second state to remove the material 10 adhered to the side of the valve core 300, thereby ensuring the sealing of the connection between the valve core 300 and the discharge channel 100 in the first state, reducing the risk of material leakage at the discharge port 110, and ensuring the normal use of the product.

[0041] like Figure 2 As shown, in the second state, the axis of the valve core 300 of this embodiment is perpendicular to the axis of the discharge channel 100, and the first air outlet 210 is directly opposite to the side of the valve core 300. Through the above arrangement, in the second state, the material adhered to the side and lower part of the side of the valve core 300 can fall off from the valve core 300 under the action of gravity and the gas blown out of the first air outlet 210, and the material 10 adhered to the top of the side of the valve core 300 can fall off from the valve core 300 under the action of the gas blown out of the first air outlet 210, thereby ensuring that there is no adhered material on the valve core 300, ensuring that in the first state, the valve core 300 can be sealed and connected with the discharge channel 100 to prevent material leakage and ensure the normal use of the product.

[0042] like Figure 1As shown, the first flange 200 of this embodiment is further provided with a first air inlet 220, which is used to connect to an air source. For example, the first air inlet 220 and the air source can be connected through an air pipe. The first air inlet 220 and the first air outlet 210 can be respectively located on two opposite surfaces of the first flange 200, thereby facilitating the arrangement of the air pipe. A first air passage connecting the first air inlet 220 and the first air outlet 210 is provided in the first flange 200, so that the first air outlet 210 can be connected to the air source.

[0043] In order to further improve the sealing performance of the valve core 300 and the discharge channel 100 in the first state, the present embodiment further provides an RF sealing surface 120 on the inner wall of the discharge channel 100, and a sealing gasket is provided on the side of the valve core 300; in the first state, the RF sealing surface 120 and the sealing gasket are sealed and connected, thereby further preventing material leakage.

[0044] Furthermore, the sealing pad of this embodiment may be a rubber pad.

[0045] Please continue to refer to Figure 1 In this embodiment, the first flange 200 is further provided with a second air inlet 230, and the second air inlet 230 is connected to an air source, for example, the second air inlet 230 can be connected to the air source through an air pipe. The inner wall of the discharge channel 100 is provided with a plurality of second air outlet holes 130, and the plurality of second air outlet holes 130 are all connected to the second air inlet 230.

[0046] In this embodiment, by providing the second air inlet 230 and the plurality of second air outlets 130 , the plurality of second air outlets 130 can be used to blow air toward the valve core 300 in the first state, so as to further reduce the probability of the material adhering to the valve core 300 .

[0047] Furthermore, in this embodiment, the plurality of second air outlet holes 130 are distributed at intervals along the circumference of the discharge channel 100 , and the plurality of second air outlet holes 130 form a ring, so that the second air outlet holes 130 can blow to any part of the side of the valve core 300 .

[0048] Optionally, the discharge channel 100 of this embodiment may be conical, and the cross-sectional area of ​​the discharge channel 100 gradually decreases in the direction away from the discharge port 110. The second air outlet 130 is arranged obliquely with the discharge channel 100, so as to facilitate blowing off the material adhering to the valve core 300.

[0049] In this embodiment, two second air inlet holes 230 may be provided, and the two second air inlet holes 230 may be respectively located at both ends of the first flange 200. 4-12 second air outlet holes 130, for example 8, may be provided in the discharge channel 100, wherein each second air inlet hole 230 may be connected to four second air outlet holes 130, thereby facilitating reducing the length of the air pipe connecting the second air inlet hole 230 and the second air outlet hole 130.

[0050] Please continue to refer to Figure 1 and Figure 2 The discharge valve assembly of this embodiment further includes a second flange 400 and a swing arm 500. One end of the swing arm 500 is connected to the valve core 300, and the other end of the swing arm 500 is used to connect to a driving device. The driving device can drive the swing arm 500 to swing, and the specific swing angle can be set as required. The discharge channel 100, the first flange 200, the valve core 300 and the swing arm 500 are all located in the second flange 400, and the second flange 400 is used to realize the connection between the discharge valve assembly and other equipment.

[0051] This embodiment also provides a plowshare mixer, comprising the above-mentioned discharge valve assembly.

[0052] Specifically, the discharge valve assembly is arranged at the lower part of the plowshare mixer. Due to the use of the above-mentioned discharge valve assembly, the plowshare mixer of this embodiment can reduce the risk of material leakage at the discharge port when in use, thereby ensuring the normal use of the product.
