Technical Field

[0001] The invention discloses an anti-jamming closed material distributor capable of moving with materials, which is applied to the unloading of solid material bins. Background Art

[0002] In the field of industrial production, the bottom unloading equipment of the silo storing solid materials often needs to carry the material for unloading and closing. According to the production process requirements, there are often multiple unloading ports, which are unloaded to the corresponding channels as needed. When carrying the material, the solid material is easy to enter the movement gap of the unloading equipment, causing obstruction, and with the unloading of the material, there is often dust, and even toxic and harmful gases overflow. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention provides an anti-jamming closed material distributor that can move with materials, which not only ensures reliable opening and closing actions, but also prevents dust or toxic and harmful gases from overflowing.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:

[0006] The valve plate moves up to the first station, the bottom outlet of the silo, the valve plate feed port and the first discharge port are connected to realize right discharge, and the extension direction of the first discharge port is parallel to the movement direction of the valve plate;

[0007] The valve plate moves to the second station, the bottom outlet of the silo, another discharge port of the valve plate and the second discharge port are connected to realize left discharge, and the extension direction of the second discharge port is perpendicular to the movement direction of the valve plate;

[0008] The valve plate moves to the third position, and the valve plate blocking part seals the bottom outlet of the silo, thereby isolating the left and right unloading channels, and the distributor is closed without unloading.

[0009] Furthermore, the distributor is installed at the bottom outlet of the silo through a flange. The bottom outlet of the silo is inclined. The plane where the bottom outlet of the silo is located forms an angle a with the horizontal, and the angle is greater than the repose angle of the material.

[0010] Furthermore, a middle partition is provided in the distributor housing, the partition is located at one side of the second discharge port and extends toward the distributor docking port, and the top of the middle partition is located below the moving track of the valve plate.

[0011] Furthermore, the top of the middle partition is an inclined surface, which is close to the valve plate. When the valve plate moves, it cooperates with the middle partition and cooperates to connect the bottom outlet of the silo with the discharge port of the distributor to form a first discharge channel or a second discharge channel. A wear-resistant lining is provided on the side of the middle partition.

[0012] Furthermore, the discharge openings of the valve plate are a left discharge opening and a discharge opening, and the two discharge openings are respectively located at the front and rear sides of the blocking portion along the moving direction of the valve plate.

[0013] Furthermore, the widths of the left and right feed openings of the valve plate are both smaller than the width of the valve plate, so that the roller is appropriately away from the feed opening.

[0014] Furthermore, two rows of rollers are arranged on both sides of the valve plate, each roller is fixed on the distributor housing, and each row of rollers is staggeredly arranged along the upper and lower surfaces of the valve plate.

[0015] Furthermore, a boss is provided on the side of the roller near the valve plate, and the valve plate moves within the track defined by the roller boss, which can effectively limit the left and right swing of the valve plate during movement, so that the valve plate moves in a straight line as much as possible.

[0016] Furthermore, a purge gas interface is provided at the front end of the distributor housing for passing purge gas or high-temperature gas.

[0017] Furthermore, the bottom and side walls of the distributor shell are provided with wear-resistant linings to prevent the distributor from wearing out too quickly and extend the service life of the equipment.

[0018] The present invention is applied to the unloading of solid material bins. The hydraulic cylinder drives the valve plate to move between the rollers to realize the "right discharge", "close" and "left discharge" actions. Since the distributor is tilted as a whole, it is not necessary to overcome the gravity of the material in the bin during the action, and the action load is small, which is both energy-saving and safe and reliable. The distributor of the present invention is sealed as a whole, with only a feed port connected to the bin and right and left discharge ports connected to the next process, which can avoid dust or possible spillage of toxic and harmful gases, ensuring environmental protection and safety.

[0025] The present invention will be further described below in conjunction with the accompanying drawings:

[0026] Example: See Figures 1 to 5 , an anti-jamming closed type distributor that can act with materials, including a distributor housing 2, a hydraulic cylinder 3 and a valve plate 4, the hydraulic cylinder 3 is installed on the distributor housing 2, the piston end of the hydraulic cylinder 3 extends into the distributor housing 2 and is connected to the valve plate 4, the valve plate 4 has a first position, a second position and a third position along the direction of the piston rod driven by the hydraulic cylinder 3, the valve plate 4 is provided with a blocking portion and a feed opening or a discharge opening, one side of the distributor housing 2 is provided with a docking port to dock with the bottom outlet of the silo 1, the distributor as a whole forms an angle a with the horizontal, the angle is greater than the repose angle of the material, the distributor housing 2 has a first discharge port and a second discharge port, the working mode of the valve plate of the present invention is as follows:

[0027] Right discharge mode, such as Figure 1 As shown, the valve plate 4 moves up to the first working position, the bottom outlet of the silo, the valve plate feed port and the first discharge port are connected to realize right discharge, and the extension direction of the first discharge port is parallel to the movement direction of the valve plate;

[0028] Left discharge mode, such as Figure 3 As shown, the valve plate 4 moves to the second station, the bottom outlet of the silo, another discharge port of the valve plate and the second discharge port are connected to realize left discharge, and the extension direction of the second discharge port is perpendicular to the movement direction of the valve plate 4;

[0029] Close mode, such as Figure 2 As shown, the valve plate 4 moves to the third station, which is located between the first and second stations. The valve plate blocking portion seals the bottom outlet of the silo, thereby blocking the left and right unloading channels, and the distributor is closed without unloading.

[0030] See also Figures 1 to 4 The distributor of the present invention is installed at the bottom outlet of the silo through a flange. The bottom outlet of the silo is inclined. The plane where the bottom outlet of the silo is located forms an angle a with the horizontal, and the angle is greater than the angle of repose of the material. An intermediate partition 7 is provided in the distributor housing 2. The partition is located on one side of the second discharge port and extends toward the distributor docking port. The top of the intermediate partition 7 is located below the moving track of the valve plate 4. The top of the intermediate partition 7 is an inclined surface, and the inclined surface is close to the valve plate. When the valve plate 4 moves, it cooperates with the intermediate partition 7 and cooperates to connect the bottom outlet of the silo with the distributor discharge port to form a first discharge channel or a second discharge channel. A wear-resistant lining is provided on the side of the intermediate partition 7. Figure 4As shown, the discharge ports of the valve plate 4 are the left discharge port 41 and the right discharge port 42, which are respectively located at the front and rear sides of the blocking portion along the moving direction of the valve plate, and the valve plate blocking portion is between the two discharge ports for blocking the discharge. The widths of the left and right discharge ports 41 and the right discharge port 42 of the valve plate are both smaller than the width of the valve plate 4, so that the roller 5 is appropriately away from the discharge ports.

[0031] See also Figures 1 to 5 In one embodiment of the present invention, two rows of rollers 5 are arranged on both sides of the valve plate 4. Each roller 5 is fixed on the distributor housing 2, and each row of rollers is arranged alternately along the upper and lower surfaces of the valve plate 4. The rollers 5 are provided with bosses 51 near the side of the valve plate. The valve plate 4 moves in the track defined by the roller bosses, which can effectively limit the left and right swing of the valve plate 4 when it moves, so that the valve plate 4 moves in a straight line as much as possible.

[0032] See also Figure 1 , Figure 5 A purge gas interface 21 and a purge gas interface 22 are provided at the front end of the distributor housing 2 for passing purge gas or high-temperature gas.

[0033] The structure of an embodiment of the present invention is as follows:

[0034] The whole set of equipment is installed at the bottom of the silo 1 through a flange, the hydraulic cylinder 3 is installed on the distributor housing 2, and the end of the hydraulic cylinder piston rod is hinged to one end of the valve plate 4. Two rows of rollers 5 are arranged on both sides of the valve plate, and the rollers are fixed on the distributor housing. Each row of rollers is staggered along the upper and lower surfaces of the valve plate.

[0035] By retracting and extending the hydraulic cylinder 3, the valve plate 4 is driven to move upward and downward along the roller, thereby realizing the switching of the distributor's "right discharge", "closed" and "left discharge" states. Figure 1 , 2 , 3. When discharging from the right (left), the valve plate 4 moves up to a fixed position, and the right (left) discharge port on the valve plate 4 is connected with the bottom of the silo and the right (left) discharge port of the distributor, so as to realize the right (left) discharge. At this time, the left (right) discharge port of the valve plate deviates from the bottom of the silo, and the left (right) discharge channel is cut off; when the distributor is closed, the valve plate moves to the middle fixed position, and the left and right discharge ports of the valve plate 4 deviate from the bottom of the silo, and the left and right discharge channels are cut off, so as to realize the closure without discharging.

[0036] In the present invention, the feed opening is also referred to as a discharge opening, such as the left feed opening is referred to as a left discharge opening, and the right feed opening is referred to as a right discharge opening.

[0037] The technical advantages of the present invention are as follows:

[0038] ① The hydraulic cylinder 3 drives the valve plate 4 to move between the rollers 5 to achieve the "right discharge", "closed" and "left discharge" actions. During the action, it is only necessary to overcome the friction between the roller 5 and the valve plate 4 and the friction between the valve plate 4 and the material, without overcoming the gravity of the material in the silo, and the action load is small; at the same time, no matter which discharge port is closed or both discharge ports are closed, the gravity of the material in the silo above the closed port is transmitted to the roller by the valve plate, and the valve drive mechanism hydraulic cylinder itself does not need to provide additional power. Even if the power oil of the hydraulic cylinder is interrupted, as long as the oil pressure in the hydraulic cylinder is locked, the valve will not malfunction, which is both energy-saving and safe and reliable.

[0039] ② The distributor as a whole forms an angle "a" with the horizontal, which is greater than the repose angle of the material, ensuring that no material will accumulate on the valve plate and roller. After the valve is closed, no material will accumulate in the lower inner cavity of the valve, thus avoiding valve jamming when opening and closing.

[0040] ③ The width of the left and right discharge ports of the valve plate 4 are appropriately smaller than the width of the valve plate, so that the roller 5 is appropriately away from the discharge port, which can reduce the impact of the material flow on the roller when the distributor is in operation and minimize obstruction.

[0041] ④ The areas in contact with the materials such as the bottom and side walls of the distributor housing 2 and the middle partition are all provided with wear-resistant lining plates 6, and the valve plate 4 itself is made of wear-resistant material to avoid excessive wear of the housing and the valve plate, thereby extending the service life of the equipment.

[0042] ⑤ The roller 5 is designed with a boss on the side close to the valve plate 4, see Figure 4 , which can effectively limit the left and right swing of the valve plate when it moves, and make the valve plate move in a straight line as much as possible.

[0043] ⑥ Each row of rollers 5 is staggered along the upper and lower surfaces of the valve plate, which can limit the displacement of the valve plate 4 perpendicular to the plate surface when the valve plate 4 moves, and the valve plate 4 runs more smoothly.

[0044] ⑦ Two purge gas interfaces 21 and 22 are provided at the front end of the distributor housing 2. Figure 5 As shown, purge gas can be introduced to regularly purge the valve plate, roller, track and other parts. If the material has a high moisture content, high-temperature gas can also be introduced, which has the following three functions: 1) Dry and clean the internal cavity of the valve, especially the valve plate, roller and other parts; 2) By maintaining a certain temperature in the cavity, condensation in the cavity can be prevented and powder ash adhesion can be reduced. 3) In winter or other working conditions with low ambient temperature, high-temperature gas drying and heating can prevent ice and freezing inside the equipment. Ensure the reliability of equipment operation to the greatest extent.

[0045] ⑧The distributor is completely closed, with only the feed port connected to the silo and the right and left discharge ports connected to the next process, which can avoid the overflow of dust or possible toxic and harmful gases, ensuring environmental protection and safety.
