Description

Technical Field

[0001] The invention relates to the technical field of blockage clearing devices, and in particular to a device for cleaning and clearing blockages in a lower warehouse wall of a material warehouse. Background Art

[0002] In daily industrial and agricultural production, the use of storage bins for granular materials such as raw coal and ore powder is very popular. However, during the discharge process of the storage bins, material blockage often occurs, seriously affecting the normal operation of the equipment. For example, raw coal bins in large thermal power plants and coal towers in coking plants are often blocked. If coal discharge is blocked in power plants, the generator sets will be forced to reduce output and shed load urgently, and may even cause boiler extinguishing and unplanned shutdown of the units. Once coal discharge is blocked in coking plants, the entire coal distribution ratio will be out of balance, which may lead to coal transportation interruption in severe cases, causing huge economic losses.

[0003] In view of this type of blockage in large silos, currently commonly used means of clearing blockages include manual clearing, silo wall vibrators, loosening machines, etc. Manual blockage breaking usually includes poking coal through coal holes, hitting the blocked coal parts with a sledgehammer, and setting a bell-type heavy hammer outside the silo at the place where coal is easily blocked. Such methods are time-consuming and labor-intensive, and are likely to cause damage to the silo wall. The blocking breaking principle of the silo wall vibrator is to gradually separate the coal adhered to the silo wall through the vibration of the silo wall to achieve the purpose of blocking, which will also cause damage to the silo wall. The principle of the raw coal silo loosening machine is to drive the coal plow to reciprocate through the hydraulic cylinder on the outside of the silo wall, and at the same time use its coal plow blades to scrape the raw coal in the blocked area, destroy its dense extrusion structure, and restore the flow of coal. The coal plow is generally designed horizontally inside the silo wall, and the coal blocks are easy to move up and down with the coal plow. Although it can achieve the purpose of unblocking coal blocks, the horizontally designed coal plow push plate can easily cause secondary blockage of coal blocks. There is also a rotary blockage clearing machine on the market The rotary blockage clearing machine changes the lower silo section of the material bin from the original integrated bin body to a rotary bin body. The arch-breaking and blockage clearing knife installed in the wall of the rotary bin body and the rotary bin body constitute a relative motion system. During this relative motion process, the material cannot form a stable arch with the inner wall of the rotary bin body and the bin wall, and the basic factors of blockage are destroyed and disintegrated in time, thereby achieving the purpose of better preventing material blockage and significantly improving the anti-blocking effect. It consists of a fixed bin, a rotary bin and a lower fixed bin. The rotary bin section is in the easy-to-block section of the entire material bin and is the key component for solving the blockage problem of the entire material bin. When the raw coal bin is blocked, the rotary bin body begins to rotate, and the material and the bin wall move relative to each other. At this time, the material cannot form a stable arch with the bin wall on the inner side of the bin wall, which can solve the coal blockage problem of the raw coal bin to a certain extent. However, when the rotary blockage clearing machine is used for a long time, the rotary bin of the rotary blockage clearing machine will still adhere to the coal slag, and blockage will still occur after long-term use.

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] Example 1

[0033] A device for cleaning and unblocking the lower wall of a material bin comprises a first tube body 1 and a second tube body 2 arranged at the bottom of the first tube body 1, a rotating ring 3 is arranged between the first tube body 1 and the second tube body 2, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in the present application, the first tube body 1 is used to be installed at the bottom discharge port position of the lower silo section of the material bin, and the first tube body 1 and the second tube body 2 are both installed with a first fixing block 10 and a second fixing block 11, and the limit bolt 12 is screwed between the second fixing block 11 on the first tube body 1 and the first fixing block 10 on the second tube body 2, so that the first tube body 1 and the second tube body 2 can be fixed together, and the rotating ring 3 is between the first tube body 1 and the second tube body 2, and the first tube body 1 and the second tube body 2 fix it;

[0034] Furthermore, the top and bottom of the rotating ring 3 are both equipped with sealing sliders 14, and the opposite sides of the first tube body 1 and the second tube body 2 are provided with sealing slide grooves 15 slidably connected to the sealing slider 14, the inner wall diameter of the rotating ring 3 is consistent with the inner wall diameter of the first tube body 1 and the inner wall diameter of the second tube body 2, and the outer wall diameter of the rotating ring 3 is consistent with the outer wall diameter of the first tube body 1 and the outer wall diameter of the second tube body 2, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the sealing slider 14 is designed at the bottom and top of the rotating ring 3, and the sealing groove 15 is designed on the side opposite to the first tube body 1 and the second tube body 2. When the rotating ring 3 rotates, the sealing slider 14 can be driven to rotate inside the sealing groove 15. The sealing slider 14 and the sealing groove 15 limit the rotation of the rotating ring 3 between the first tube body 1 and the second tube body 2, and can also reduce the friction of the rotation of the rotating ring 3 to prevent material residues from entering the gap between the first tube body 1 and the second tube body 2 and the rotating ring 3. The inner diameter and outer diameter of the first tube body 1 and the second tube body 2 are consistent with the rotating ring 3, which can ensure that there will be no jamming when the material is unloaded, thereby ensuring smooth unloading.

When the cleaning block 5 rotates inside the first tube body 1 and the second tube body 2, the inner wall of the first tube body 1 and the second tube body 2 is cleaned and dredged, thereby preventing blockage accidents. This transmission method is suitable for tube walls with thinner diameters, shorter tube lengths, and smaller loads. It is simple and effective.

Figure 8 , Fig. 9 and Fig.10 As shown, the universal ball 22 is located between the first universal groove 20 and the second universal groove 21, and there are multiple universal balls 22, which are arranged in a ring-shaped and equidistant manner. The same number of universal balls 22 are designed between the first tube body 1 and the rotating ring 3, and between the second tube body 2 and the rotating ring 3. When the rotating ring 3 rotates between the first tube body 1 and the second tube body 2, the rotating body can be supported, the friction between the rotating ring 3 and the first tube body 1 and the second tube body 2 can be reduced, and the accuracy of rotation can be ensured.

[0037] Furthermore, for the discharge pipe of the discharge bin that requires a longer diameter, multiple sets of cleaning and unblocking devices can be used in series to prevent the steel bars from breaking.

[0039] Further, an annular delivery pipe 16 is provided on the surface of the first tube body 1, an exhaust groove 17 is provided inside the inner wall of the first tube body 1, a plurality of air supply pipes 18 are connected to the surface of the annular delivery pipe 16, and one end of the air supply pipe 18 is connected to the exhaust groove 17, the lowest surface of the exhaust groove 17 is an inclined surface, the shape of the exhaust groove 17 is a triangle, the exhaust groove 17 is connected to the inner cavity of the first tube body 1, the surface of the annular delivery pipe 16 is connected to an external air pipe 19, and the other end of the external air pipe 19 is installed with a flange, such as Figure 6 and Figure 7 As shown, the annular conveying pipe 16 is designed on the surface of the first tube body 1, and the exhaust groove 17 is designed on the inner wall of the first tube body 1. The bottom surface of the exhaust groove 17 is an inclined groove body. This design is convenient for material unloading and prevents the material from falling into the exhaust groove 17 and being unable to fall. The annular conveying pipe 16 and the exhaust groove 17 are connected through the air supply pipe 18. The hot dry gas inside the annular conveying pipe 16 can be transported to the exhaust groove 17 through the air supply pipe 18. The hot dry gas enters the interior of the first tube body 1 and contacts with the material, which can dry the material, prevent the material from increasing in humidity due to the rainy season, and ensure the normal unloading of the material. The external air pipe 19 is used to connect external hot dry gas equipment to facilitate the external hot drying equipment to transport the gas to the inside of the annular conveying pipe 16.
