Description

Technical Field

[0001] This invention belongs to the field of discharge valve technology, and particularly relates to a powder discharge valve and discharge method. Background Technology

[0002] Discharge valves are used for discharging solid particles or dusty materials or for feeding materials to other devices. They are widely used in many industries such as coal, metallurgy, and cement. Depending on the specific application of the working material, discharge valves sometimes need to operate at high temperatures for discharging high-temperature materials.

[0003] In modern life, discharge valves are used in many devices, where they are needed to improve efficiency. However, existing discharge valves can only discharge fine particles and dust, and cannot discharge round materials. When large particles are discharged, blockages will occur. Furthermore, they do not have the ability to classify large particles and dust materials, which greatly reduces the discharge efficiency, increases the failure rate, and is particularly inconvenient for users. Summary of the Invention

[0004] To address the problems existing in the prior art, this invention provides a powder discharge valve and discharge method, which has the advantages of improving discharge efficiency and reducing failure rate. It solves the problems of existing discharge valves that can only discharge fine particles and dust, cannot discharge spherical materials, and will cause blockage when large particles are discharged. At the same time, it does not have the ability to classify large particles and dust materials for discharge, which greatly reduces the discharge efficiency, increases the failure rate, and is particularly inconvenient for users.

[0005] This invention is implemented as follows: a powder discharge valve and discharge method, comprising an outer shell, an inner barrel movably connected to the inner wall of the outer shell, a feed hopper fixedly connected to the top and bottom of the inner barrel, a first lead screw and a second lead screw movably connected to the inner wall of the inner barrel respectively, the surface of the second lead screw being fixedly connected to the inner barrel, the right side of the second lead screw penetrating to the right side of the inner barrel and extending to the right side of the outer shell, a universal joint fixedly connected to the right side of the second lead screw, a motor fixedly connected to the right side of the universal joint, the left side of the first lead screw penetrating to the left side of the inner barrel and extending to the left side of the outer shell, a four-bar linkage mechanism sleeved on the surface of the first lead screw, fixed blocks fixedly connected to the top and bottom of the four-bar linkage mechanism, movable plugs fixedly connected to opposite sides of the two fixed blocks, and ball valves for use with the movable plugs fixedly connected to the top and bottom of the inner barrel.

[0006] As a preferred embodiment of the present invention, the number of feeding hoppers is eight, and the top and bottom of the inner barrel are provided with feeding ports that cooperate with the feeding hoppers.

[0007] As a preferred embodiment of the present invention, the four-bar linkage includes four connecting rods and two pistons. A threaded rod is provided between the opposite sides of the two pistons. A threaded sleeve is fitted on the surface of the threaded rod. There are two threaded sleeves. The four connecting rods are movably connected to each other through a rotating rod. The connecting rods are movably connected to the pistons through the rotating rods. The opposite sides of the two threaded sleeves are fixedly connected to the connecting rods. The threaded rod is a bidirectional threaded rod.

[0008] As a preferred embodiment of the present invention, the powder discharge valve and discharge method include the following discharge method:

[0009] Step 1: Start the motor, rotate it 90 degrees, and open the ball valve;

[0010] Step 2: The material passes through the ball core opening, enters the shaft tube, and is discharged from the lower ball core opening;

[0011] Step 3: Complete the material arrangement;

[0012] Step 4: Reverse the motor by 90 degrees to close the valve.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. This invention solves the problems of existing discharge valves, which can only discharge fine particles and dust, but cannot discharge round materials, and will cause blockage when large particles are discharged. It also lacks the ability to classify large particles and dust materials, which greatly reduces the discharge efficiency, increases the failure rate, and is particularly inconvenient for users.

[0015] 2. By using the feed inlet and feed hopper in combination, the inner barrel can be rotated so that the feed hopper and feed inlet are aligned, thus realizing the feeding function. At the same time, when the feed inlet and feed hopper are misaligned, a sealing effect can be achieved.

[0016] 3. By setting up a four-bar linkage, the present invention enables the bidirectional threaded rod to drive the two threaded sleeves to move in opposite directions through the rotation of the rotating rod, so that the two threaded sleeves drive the connecting rod to move, and the connecting rod can drive the two pistons to open and close simultaneously.

[0017] 4. By setting a powder discharge valve and a discharge method, the present invention enables the device to discharge materials evenly, and spherical materials will not get stuck during discharge, thus preventing the device from clogging and allowing for flexible switching between sealing and opening.

[0023] To further understand the content, features, and effects of this invention, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0024] The structure of the present invention will now be described in detail with reference to the accompanying drawings.

[0025] like Figures 1 to 4 As shown, an embodiment of the present invention provides a powder discharge valve and discharge method, including an outer shell 1, an inner barrel 10 movably connected to the inner wall of the outer shell 1, a feed hopper 3 fixedly connected to the top and bottom of the inner barrel 10, a first lead screw 6 and a second lead screw 9 movably connected to the inner wall of the inner barrel 10, the surface of the second lead screw 9 fixedly connected to the inner barrel 10, the right side of the second lead screw 9 penetrating to the right side of the inner barrel 10 and extending to the right side of the outer shell 1, a universal joint 4 fixedly connected to the right side of the second lead screw 9, a motor 5 fixedly connected to the right side of the universal joint 4, the left side of the first lead screw 6 penetrating to the left side of the inner barrel 10 and extending to the left side of the outer shell 1, a four-bar linkage 8 sleeved on the surface of the first lead screw 6, a fixed block 11 fixedly connected to the top and bottom of the four-bar linkage 8, a movable plug 2 fixedly connected to opposite sides of the two fixed blocks 11, and a ball valve 7 for use with the movable plug 2 fixedly connected to the top and bottom of the inner barrel 10.

[0026] refer to Figure 1 , Figure 2 and Figure 3 There are eight feeding hoppers 3, and the top and bottom of the inner barrel 10 are provided with feeding ports 12 that are used in conjunction with the feeding hoppers 3.

[0027] The above solution allows the inner barrel 10 to rotate by using the feed inlet 12 and the feed hopper 3 together. When the feed hopper 3 and the feed inlet 12 overlap, the feeding function can be realized. At the same time, when the feed inlet 12 and the feed hopper 3 are misaligned, the sealing effect can be achieved.

[0028] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The four-bar linkage 8 includes four connecting rods and two pistons. A threaded rod is provided between the opposite sides of the two pistons. The surface of the threaded rod is fitted with a threaded sleeve. There are two threaded sleeves. The four connecting rods are movably connected to each other through a rotating rod. The connecting rods are movably connected to the pistons through the rotating rods. The opposite sides of the two threaded sleeves are fixedly connected to the connecting rods. The threaded rod is a bidirectional threaded rod.

[0029] The above scheme is adopted: by setting a four-bar linkage 8, the bidirectional threaded rod can drive the two threaded sleeves to move in opposite directions through the rotation of the rotating rod, so that the two threaded sleeves drive the connecting rod to move, and the connecting rod can drive the two pistons to open and close simultaneously.

[0030] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 The powder discharge valve and discharge method include:

[0031] Step 1: Start motor 5, rotate it 90 degrees, and open ball valve 7;

[0032] Step 2: The material passes through the ball core opening, enters the shaft tube, and is discharged from the lower ball core opening;

[0033] Step 3: Complete the material arrangement;

[0034] Step 4: Reverse motor 5, rotate it 90 degrees to close the valve.

[0035] By adopting the above scheme, the discharge method of setting the powder discharge valve and the discharge method can make the device discharge evenly, and at the same time, spherical materials will not get stuck during discharge, so that the device will not be blocked and can be flexibly switched between sealing and opening.

[0036] Working principle of the invention:

[0037] In use, when material enters from the feed hopper 3, the motor 5 is started and rotated 90 degrees, driving the universal joint 4 to rotate. The rotation of the universal joint 4 drives the second lead screw 9 to rotate, which in turn drives the inner barrel 10 to rotate, causing the feed hopper 3 to coincide with the feed inlet 12. This allows the material to enter the inner barrel 10 from the feed inlet 12 and be discharged from the lower outlet. When round material needs to be discharged, the rotation of the second lead screw 9 drives the four-bar linkage 8 to move, causing the movable plug 2 to disengage from the inner cavity of the ball valve 7, allowing the round material to be discharged. After discharge is completed, the motor 5 is reversed 90 degrees to close the valve.

[0038] In summary, this powder discharge valve and method, through the coordinated use of the outer shell 1, movable plug 2, feed hopper 3, universal joint 4, motor 5, first lead screw 6, ball valve 7, four-bar linkage 8, second lead screw 9, inner barrel 10, fixed block 11, and feed port 12, solves the problems of existing discharge valves that can only discharge fine particles and dust, cannot discharge spherical materials, and will cause blockage when large particles are discharged. Furthermore, it lacks the ability to classify large particles and dust materials, greatly reducing discharge efficiency, increasing the failure rate, and being particularly inconvenient for users.
