Description

[0002] Coal gangue is a solid waste produced in the process of coal mining and washing, and its reasonable utilization has been an important research direction in the field of resource comprehensive utilization. Preparing coal gangue into mortar for the construction industry not only realizes the resource utilization of waste, but also has significant environmental and economic benefits. In the production process of coal gangue mortar, the packaging buffer bin is an indispensable key equipment. It not only plays a role in temporary storage and buffering of materials, but also ensures the stability and continuity of materials during packaging.

[0003] However, due to the hardness and edges of coal gangue particles, strong wear will occur on the inner wall of the packaging buffer bin during the flow and impact of the materials. In order to improve the wear resistance of the buffer bin and prolong its service life, a wear-resistant rubber plate is usually installed inside the bin body. However, the wear-resistant rubber plate used in traditional packaging buffer bins is usually of a monolithic structure, and once wear occurs in part of the area, the entire wear-resistant rubber plate needs to be replaced. This replacement method results in the waste of a large amount of non-worn rubber plate, increasing the production cost. UTILITY MODEL CONTENT

DETAILED DESCRIPTION

[0023] In order to make the purpose and advantages of the utility model more clear and obvious, the following will specifically describe the utility model with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the specific protection scope requested by the utility model.

[0024] As shown in Figures 1-4 A special packaging buffer bin for coal gangue prepared mortar includes a rack 1, the rack 1 is fixedly connected with a bin body 2, the included angle between the inner wall of the bin body 2 and the horizontal plane is adjusted from 55° of the prior art to 75°, so that the material unloading is more smooth, the lower end of the bin body 2 is fixedly connected with two butterfly valves 4 arranged in an upper-lower overlapping mode, the diameter of the butterfly valve 4 is DN300, compared with a single butterfly valve 4, the two butterfly valves 4 can ensure the storage of materials during maintenance.

[0025] Due to the reason that the coal gangue prepared mortar is easy to wear due to needle-shaped, when designing the packaging bin of coal gangue mortar, the wear problem needs to be fully considered, therefore, the utility model is fixedly connected with a wear-resistant rubber plate 3 on the inner side of the bin body 2 to reduce wear.

[0026] As shown in Figures 1-3 In order to reduce the consumption of the wear-resistant rubber plate 3, the utility model improves the wear-resistant rubber plate 3, which specifically includes a plurality of annular rubber plates 5, and can also include a plurality of arc-shaped rubber plates 6.

[0027] The plurality of annular rubber plates 5 are detachably fixedly connected on the inner wall of the bin body 2 in the order from bottom to top, at this time, since the contact between the wear-resistant rubber plate 3 inside the bin body 2 and the coal gangue mortar needle-shaped is that the lower part of the wear-resistant rubber plate 3 contacts more with the mortar needle-shaped, and the upper part of the wear-resistant rubber plate 3 contacts less with the mortar needle-shaped, the utility model divides the wear-resistant rubber plate 3 into a plurality of annular rubber plates 5 arranged in sequence from top to bottom, which can directly replace the annular rubber plate 5 worn more in the corresponding area, and the remaining annular rubber plates 5 still remain on the inner wall of the bin body 2 to continue to be used, so that only the area of the wear-resistant rubber plate 3 worn more can be replaced, the replacement of the area of the wear-resistant rubber plate 3 not worn is reduced, and the consumption of the wear-resistant rubber plate 3 is reduced.

[0028] Meanwhile, the heights of the plurality of annular rubber plates 5 are sequentially reduced from bottom to top. Since the lower part of the wear-resistant rubber plate 3 is in contact with the mortar needle more, the lower annular rubber plate 5 is selected to be larger in size and more evenly worn, so that the annular rubber plate 5 can be replaced more conveniently. Since the upper part of the wear-resistant rubber plate 3 is in contact with the mortar needle less, the annular rubber plate 5 of smaller size can reduce the replacement of the non-worn area of the wear-resistant rubber plate 3.

[0029] As shown in Figures 2-3 , the plurality of arc-shaped rubber plates 6 are fixedly connected in a ring array on the inner wall of the upper side of the bin body 2, so that the arc-shaped rubber plates 6 are located on the upper side of the annular rubber plate 5. Since the upper part of the wear-resistant rubber plate 3 is in contact with the needle-shaped coal gangue mortar more when the needle-shaped coal gangue mortar falls, at this time, the needle-shaped coal gangue mortar is only in contact with one area of the arc-shaped rubber plate 6 in the horizontal plane. The present technical solution can replace only the arc-shaped rubber plate 6 which is in contact with the needle-shaped coal gangue mortar more by dividing the upper part of the wear-resistant rubber plate 3 into a plurality of arc-shaped rubber plates 6 in a ring array in the horizontal plane, thereby reducing the consumption of the wear-resistant rubber plate 3.

[0030] As shown in Figures 2-4 , the fixing methods of the annular rubber plate 5 and the arc-shaped rubber plate 6 are various, such as clamping, screw connection or magnetic attraction connection. In the present technical solution, a connecting rod 8 is fixedly connected to the outer side of the annular rubber plate 5 and the arc-shaped rubber plate 6, and a positioning groove 16 is formed in the side wall of the bin body 2. The connecting rod 8 is inserted into the inside of the positioning groove 16, and a locking piece 7 matched with the positioning groove 16 is fixedly connected to the bin body 2. The connecting rod 8 can be fixed by the locking piece 7, so as to achieve the purpose of fixing the annular rubber plate 5 and the arc-shaped rubber plate 6.

[0031] In the present technical solution, the locking piece 7 is fixedly connected to the outer side of the bin body 2, and the opening size of the positioning groove 16 is greater than the diameter of the connecting rod 8, so that the connecting rod 8 can be simply inserted into the inside of the positioning groove 16, and then the connecting rod 8 can be positioned by the locking piece 7, which facilitates the installation of the annular rubber plate 5 or the arc-shaped rubber plate 6.

[0032] As shown in Figures 2-4As shown, the locking member 7 comprises an outer shell 9 fixedly connected to the outer side of the bin body 2, the outer shell 9 is rotationally connected with a rotating rod 11, the outer side of the rotating rod 11 is fixedly connected with two threaded rods 12, the two threaded rods 12 are symmetrically arranged, so that the threaded directions of the two threaded rods 12 are opposite, the outer sides of the two threaded rods 12 are threadedly connected with connecting blocks 13, the two connecting blocks 13 are both fixedly connected with clamping blocks 10 which are slidingly connected inside the outer shell 9, at this time, the two clamping blocks 10 can be driven to move in opposite directions by rotating the rotating rod 11, so as to adjust the distance between the two clamping blocks 10, and make the two clamping blocks 10 be able to clamp the connecting rod 8.

[0033] Meanwhile, the outer side of the outer shell 9 can also be fixedly connected with a servo motor 14, the output end of the servo motor 14 is fixedly connected with the rotating rod 11, the clamping blocks 10 can be driven to move by starting the servo motor 14, so as to electrically control the position of the clamping blocks 10.

[0034] In addition, the outer shell 9 can also be provided with an opening, the opening is fixedly connected with an observation window 15 inside, the relative position relationship between the connecting rod 8 and the clamping blocks 10 can be observed by the setting of the observation window 15.

[0035] The above is only the preferred embodiment of the present application, it should be pointed out that, for those skilled in the art, without departing from the principles of the present application, can make a number of improvements and refinements, these improvements and refinements should also be considered as the protection scope of the present application. The structures, devices and operation methods not specifically described and explained in the present application, if no special description and limitation, are implemented according to the conventional means in the art.
