Description

Technical Field

[0001] The utility model belongs to the technical field of white corundum production and application, and particularly relates to a white corundum abrasive sand segment refinement and screening device. Background Art

[0002] White corundum is made of industrial alumina powder, which is melted in an electric arc at a temperature of more than 2000 degrees and then cooled. It is crushed and shaped, magnetically separated to remove iron, and sieved into various particle sizes. It has a dense texture, high hardness, and sharp-angled particles. It is suitable for the manufacture of ceramics, resin-bonded abrasives, as well as grinding, polishing, sandblasting, precision casting (special corundum for precision casting), etc. It can also be used to manufacture advanced refractory materials.

[0003] Existing white corundum can be divided into segmented sand, fine powder, granular sand and micro powder according to the size of the particle size. Among them, segmented sand is mainly divided into four specifications, namely: 0-1mm particle size, 1-3mm particle size, 3-5mm particle size and 5-8mm particle size. Therefore, the existing fine screening device mainly screens out these four specifications. Since white corundum is an abrasive, this leads to excessive friction between the white corundum and the screen during the vibration screening process, which makes the screen easily damaged. In the existing design, the filter screen is mostly fixed on the screening device, which makes it inconvenient to replace after damage, and each replacement requires a lot of time.

DETAILED DESCRIPTION

[0019] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0021] Embodiment 1, as Figure 1 to Figure 4 As shown, this embodiment aims to provide a white corundum abrasive sand segment refinement and screening device, so as to facilitate the replacement of the screen 4 and meet the needs of screening white corundum abrasive sand segments. To this end, the white corundum abrasive sand segment refinement and screening device provided in this embodiment includes a device housing 1 and a feed hopper 11 arranged on the top of the device housing 1. In this embodiment, the device housing 1 is arranged in a rectangular parallelepiped shape as a whole, and the feed hopper 11 is arranged close to one side of the device housing 1. A screen 4 is arranged in the device housing 1, and the screen 4 is vibrated and tilted in the device housing 1. In this way, after vibration screening, particles of the desired size are obtained. The above structure is an existing common structure, so it is not described in detail in this embodiment.

[0022] In order to improve the vibration effect and reduce the motor power required for vibration, in the present embodiment, a vibration frame 2 is provided in the device housing 1. The setting of the vibration frame 2 is mainly to replace the original vibration of the whole machine with the vibration of the vibration frame 2. In this way, the power of the motor required can be reduced, and at the same power, the vibration effect is better.

[0023] In order to complete the screening work, the vibration frame 2 is set in a rectangular box shape. The top opening of the vibration frame 2 is designed to receive the white corundum particles from the feed hopper 11. At the same time, a vibration spring 25 is arranged between the vibration frame 2 and the device shell 1. The vibration frame 2 is fixed in the device shell 1 through the vibration spring 25. In this way, the connection between the vibration frame 2 and the device shell 1 is an elastic connection. At the same time, a vibration motor 3 is arranged at the bottom of the vibration frame 2. In this way, the vibration of the vibration frame 2 is realized by utilizing the vibration motor 3 in conjunction with the setting of the vibration spring 25.

[0024] In this embodiment, one side of the vibration frame 2 is exposed outside the device housing 1, and at the same time, the screen 4 can be inserted and pulled out from the side of the vibration frame 2 exposed to the device housing 1, so that the screen 4 can be directly replaced from the outside of the device housing 1. At the same time, a discharge port 21 matching the screen 4 is provided on the vibration frame 2. Since the screen 4 is for sorting, two discharge ports 21 are provided for one screen 4, and three discharge ports 21 are required for two screens 4, that is, the number of discharge ports 21 is the number of screens 4 plus one. In this embodiment, since the segment sand sorting is satisfied, a total of three screens 4 are provided for this purpose. At the same time, a discharge plate 12 matching the discharge port 21 is provided in the device housing 1.

[0025] In order to facilitate the insertion and withdrawal of the screen 4, in this embodiment, the screen 4 includes a screen frame 41 arranged in a frame shape and a filter 42 fixed on the top of the screen frame 41. The filter 42 is arranged on the top of the screen 4, mainly to prevent the height of the screen frame 41 from being higher than the filter 42, resulting in the occurrence of material piling.

[0026] At the same time, a C-shaped slot 23 is provided in the vibration frame 2, and the slot 23 is the existing common C-shaped channel steel. It should be noted that in order to avoid material piling caused by the slot 23, a notch is provided in the part where the screen frame 41 is inserted into the slot 23 to ensure that the top surface of the slot 23 is flush with the top surface of the filter screen 42 or lower than the top surface of the filter screen 42.

[0027] In order to further provide a vibration effect, a vibration auxiliary spring 24 is provided between the slot 23 and the vibration frame 2 .

[0028] Considering that the entire vibration frame 2 is in a vibrating state, a guide pad 22 is provided on the vibration frame 2 in order to better cooperate with the discharge plate 12. One end of the guide pad 22 is fixed to the discharge port 21, and the other end of the guide pad 22 is placed on the discharge plate 12. The top surface of the guide pad 22 is arranged parallel to the top surface of the screen 4. The guide pad 22 is made of a rubber pad. In this way, by placing the guide pad 22 on the discharge plate 12, it can be ensured that the screened white corundum abrasive sand can accurately enter the discharge plate 12.

[0029] In order to facilitate the collection of the screened white corundum sand segments, the directions of the upper and lower discharge ports 21 are arranged in different directions. In this way, it is convenient to set a conveyor belt or directly collect the materials.

[0030] In order to buffer the impact of falling materials, in this embodiment, a grinding wheel group 13 is arranged in the feed hopper 11, and the grinding wheel group 13 is rotatably arranged in the feed hopper 11. The setting of the grinding wheel group 13 has two purposes, one is to further crush the segmented sand, and the other is to buffer the speed of material discharge and increase the service life of the screen 4.

[0031] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
