Technical Field
[0001] This utility model relates to the technical field of material unloading, specifically to an unloading structure for powdery or granular materials. Background Technology
[0002] In the design of equipment such as biomass pyrolysis furnaces or activated carbon boxes, powdery or granular materials inside generally need to be discharged from the bottom of the equipment. However, most current designs currently present the following problems and inconveniences in actual operation:
[0003] 1. Uncontrollable unloading rate: Since most unloading ports are designed to open directly on the equipment, when the unloading gate is opened, a large amount of material will pour down, often accompanied by a lot of dust, which will have a great impact on the health of operators and the hygiene of the environment.
[0004] 2. Prone to clogging: If the material contains a certain amount of moisture or impurities, it will often cause the unloading to be difficult and unsmooth, and additional tools are usually required to assist in unloading;
[0005] 3. High risk: If the equipment is an industrial kiln, the furnace is often still in a high-temperature environment when unloading. If unloading is done blindly, a large amount of radiant heat from inside the furnace will be generated near the unloading port when the material is below the height of the unloading port, causing a risk. At the same time, the high-temperature dust may cause a combustion and explosion risk after being unloaded quickly and coming into contact with air.
[0006] 4. Poor sealing: If the equipment is a waste gas combustion furnace, the furnace is usually in a positive or negative pressure environment. Generally, the baffle-type discharge port will leak high-temperature gas during operation, and there are no good protective measures to prevent this phenomenon.
[0007] 5. Poor economic efficiency: Designs that can control the unloading rate and ensure safety often require the addition of motors and rotating structures, which significantly increases manufacturing costs and makes them difficult to apply widely.
[0008] Therefore, there is an urgent need to develop a structure that can solve the above-mentioned technical defects and is suitable for unloading powdery or granular materials. Utility Model Content
[0009] To address the aforementioned problems, this utility model provides a discharge structure for powdery or granular materials, which solves the issues of sealing and high temperature in the rotating parts; it also solves the problems of uncontrollable discharge rate and unsmooth discharge. The overall manufacturing cost is low, and the structure is simple and efficient.
[0010] A discharge structure for powdery or granular materials, characterized in that it is applicable to the material outlet channel of equipment and comprises:
[0011] The sealed chamber body;
[0012] Sealed compartment cover;
[0013] A rotary unloading plate includes an unloading plate body and a rotating handle protruding from the side. The unloading plate body has a plurality of first discharge ports arranged around it.
[0014] And a baffle plate, which is designed to resemble the shape of the material flow channel, and has several second discharge ports arranged around it;
[0015] The material outflow channel is cut off and divided into an inner section pipe and an outer section pipe. A baffle plate is installed at the outlet of the inner section pipe. The baffle plate and the rotating unloading plate are connected by a rotating mechanism. The rotating unloading plate rotates around the center position, so that the overlapping area of the first discharge port and the second discharge port switches from zero to complete overlap. In the state of complete overlap, the unloading flow rate is the maximum. A sealing chamber body is welded to the outer periphery of the inner section pipe and the outer section pipe corresponding to the cut thickness position. The sealing chamber body connects the inner section pipe and the outer section pipe into a whole. The upper part of the sealing chamber body is covered with the sealing chamber cover plate. When the sealing chamber cover plate is open, the rotating handle is exposed.
[0016] Its further features are:
[0017] The first discharge port and the second discharge port are several sets of fan-shaped discharge ports with the same shape, and each set of first discharge ports and second discharge ports are arranged in a one-to-one correspondence;
[0018] The rotating mechanism includes several protruding pillars and arc-shaped guide grooves. Several protruding pillars are evenly distributed on the outer ring of the exposed end face of the baffle plate. The rotating unloading plate includes at least two sets of peripheral guide arc edges. Each set of peripheral guide arc edges is provided with an arc-shaped guide groove. At least one protruding pillar is provided in the arc-shaped guide groove. The rotating handle drives the rotating unloading plate to rotate along the arc-shaped guide groove, switching the overlapping area of the first discharge port and the second discharge port.
[0019] The outer end of the protrusion is screwed with a nut, which reliably presses against the rotating unloading plate, thereby reliably blocking the second discharge port when the rotating unloading plate is not unloading.
[0020] The sealing chamber body and the sealing chamber cover are tightly attached and locked together by an outer peripheral baffle to ensure a reliable seal of the sealing chamber.
[0021] The outer periphery of the sealed chamber body is also provided with a sealed chamber air interface. When the equipment is running, the sealed chamber cover is closed and compressed air is introduced into the inner wall of the sealed chamber through the sealed chamber air interface. This ensures that high-temperature gas and heat radiation do not leak, while also maintaining a low temperature in the area of the rotating unloading plate.
[0022] The outer end of the outer section of the pipe is covered with a discharge plate, which forms a discharge port when the discharge plate is opened.
[0023] The unloading plate is fixed to the outer flange of the outer section of the pipe body through a flange structure, ensuring a stable and reliable connection.
[0024] By adopting the structure of this utility model, the original material outflow channel is cut off, forming an installation thickness space for the rotating unloading plate and the baffle plate. The rotating unloading plate and the baffle plate are assembled and connected by a rotating mechanism. Then, the inner section pipe and the outer section pipe are welded to the periphery of the cut thickness position with a sealing chamber body. The sealing chamber body connects the inner section pipe and the outer section pipe into a whole. After the sealing chamber body is covered with the sealing chamber cover plate, a sealing cavity is formed. When the sealing chamber cover plate is open, the rotating handle is exposed. By driving the rotating handle, the rotating unloading plate rotates around the center position, so that the overlapping area of the first discharge port and the second discharge port changes from zero to complete overlap. The unloading rate is observed to ensure that the unloading is at a suitable rate. If a blockage occurs, the unloading plate is rotated again to remove the stuck material. When it is necessary to stop, the rotating handle is rotated in the opposite direction to close the unloading channel. It solves the problems of sealing and high temperature of the rotating parts; and at the same time solves the problems of uncontrollable unloading rate and unsmooth unloading. Its overall manufacturing and processing cost is low, and the structure is simple and efficient. Attached Figure Description

Detailed Implementation
[0033] A discharge structure for powdery or granular materials, see Figures 1-4 It is applicable to the material outflow channel 10 of the equipment 100, which includes a sealed chamber body 20, a sealed chamber cover plate 30, a rotary unloading plate 40, and a baffle plate 50.
[0034] The rotary unloading plate 40 includes an unloading plate body 41 and a rotating handle 42 protruding from the side. The unloading plate body 41 is provided with a number of first discharge ports 43.
[0035] The baffle plate 50 is shaped to resemble the material outflow channel 10, and a number of second discharge ports 51 are arranged around the baffle plate 50.
[0036] The material outflow channel 10 is cut off and divided into an inner section pipe 11 and an outer section pipe 12. The outlet position of the inner section pipe 11 is covered with a baffle plate 50. The baffle plate 50 and the rotating discharge plate 40 are connected by a rotating mechanism 60. The rotating discharge plate 40 rotates around the center position, so that the overlapping area of the first discharge port 43 and the second discharge port 51 switches from zero to complete overlap. In the state of complete overlap, the discharge flow rate is the largest. The inner section pipe 11 and the outer section pipe 12 are welded to the periphery of the cut thickness position with a sealing chamber body 20. The sealing chamber body 20 connects the inner section pipe 11 and the outer section pipe 12 into a whole. The upper part of the sealing chamber body 20 is covered with a sealing chamber cover plate 30. When the sealing chamber cover plate 30 is open, the rotating handle 42 is exposed on the upper end face of the sealing chamber body 10.
[0037] In practice, the first discharge port 43 and the second discharge port 51 are four sets of fan-shaped discharge ports with the same shape, and the first discharge port 43 and the second discharge port 51 of each set are arranged in a one-to-one correspondence.
[0038] The rotating mechanism 60 includes several protruding posts 61 and arc-shaped guide grooves 62. Several protruding posts 61 are evenly distributed on the outer ring of the exposed end face of the baffle plate 50. The rotating unloading plate 40 includes two sets of radially symmetrically arranged peripheral guide arc edges 44. Each set of peripheral guide arc edges 44 is provided with an arc-shaped guide groove 62. At least one protruding post is provided in the arc-shaped guide groove 62. The rotating handle 42 drives the rotating unloading plate 40 to rotate along the arc-shaped guide groove 62, switching the overlapping area of the first discharge port 43 and the second discharge port 51.
[0039] A nut is screwed onto the outer end of the protruding post 61 (not shown in the figure, but can be installed according to the actual situation). The nut reliably presses against the rotating unloading plate 40, which makes the rotating unloading plate 40 reliably block the second discharge port 51 when it is not unloading.
[0040] The sealing chamber body 20 and the sealing chamber cover 30 are tightly attached and locked together by the outer peripheral baffle 1 to ensure reliable sealing of the sealing chamber.
[0041] A sealing chamber air interface 21 is also provided on the outer periphery of the sealing chamber body 20. When the equipment is running, the sealing chamber cover plate 30 is closed and compressed air is introduced into the inner wall of the sealing chamber through the sealing chamber air interface 21. This ensures that high-temperature gas and heat radiation will not leak, while also maintaining a low temperature in the area of the rotating unloading plate 40.
[0042] The outer end of the outer section pipe 12 is covered with a discharge plate 70, which forms a discharge port when the discharge plate 70 is opened.
[0043] The unloading plate 70 is fixed to the outer flange 121 of the outer section pipe body 12 through the flange structure 71 to ensure a stable and reliable connection.
[0044] In practice, the unloading plate 70 is equipped with a handle 72, and the sealed chamber cover plate 30 is equipped with a lifting handle 31 for easy operation.
[0045] In practice, the channel is closed when the rotary handle is on the right and fully open when the rotary handle is on the far left. When unloading is required, open the sealing chamber cover and the unloading plate. When unloading begins, slowly rotate the rotary unloading plate handle counterclockwise and observe the unloading rate to ensure it is at a suitable rate. If blockage occurs, rotate the unloading plate again to remove the stuck material. When stopping, rotate the rotary unloading plate handle clockwise and close the cover again. When the equipment is running, close the sealing chamber cover and introduce compressed air into the sealing chamber through the sealing chamber air mechanism. This ensures that high-temperature gas and heat radiation do not leak, while also maintaining a low temperature at the rotary unloading plate position. The rotary unloading plate is made of corrosion-resistant and high-temperature-resistant materials. During operation, the opening and closing degree of the switching valve is visually checked to ensure it is fully open or closed. The structure is simple and not prone to errors.
