Description

Technical Field

[0001] This utility model relates to the field of cementitious powder feeding equipment, and more specifically, to a cementitious powder feeding device for mine backfilling. Background Technology

[0002] Cementitious powder for mine backfilling is a material specifically used for backfilling operations in mined-out areas. Its main function is to mix with aggregates (such as tailings sand, waste rock, etc.) and water to form a backfill body with a certain strength to support the surrounding rock, prevent surface subsidence, and treat mine waste.

[0003] Traditional cementitious powder feeding devices (material silos) have the following drawbacks when in use:

Detailed Implementation

[0047] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0048] See attached document Figure 1 As shown, a cementitious powder feeding device for mine backfilling includes:

[0049] Vibration support assembly 1 is set on the ground to provide support for installation;

[0050] Material bin 2 is set on the vibrating support assembly 1 for storing adhesive powder material. The upper part of material bin 2 is circular and the lower part is conical, with the angle of the bottom of the cone being greater than 60 degrees, so as to facilitate the natural sliding of material and reduce the problem of material blockage.

[0051] The star-shaped unloader 3 is installed at the conical bottom of the material bin 2 to improve the material discharge effect during the material discharge process of the material bin 2, reduce the material blockage problem, and at the same time provide a good sealing effect to effectively reduce dust overflow.

[0052] The rotary feeder assembly 4 is located on the top of the material bin 2 and is connected to the pneumatic conveying system for feeding the cementitious powder material during implementation. This improves the sealing of the material during its entry into the material bin 2, helps reduce dust leakage, improves the working environment, and protects workers' health.

[0053] The guide pipe 5 is connected to the discharge end of the rotary feeder assembly 4 and is inclined so that the rotary feeder assembly 4 can operate to make the guide pipe 5 perform an eccentric rotation feeding action, so that the material is evenly distributed in the material bin 2.

[0054] In the specific implementation of this utility model, the material is fed through the rotary feeder assembly 4. As the rotary feeder assembly 4 rotates, the guide pipe 5 begins to rotate eccentrically within the material bin 2. This avoids the material from being fed directly from the top center of the material bin 2. The eccentric feeding method ensures that the material is evenly distributed within the material bin 2, preventing the material from settling due to gravity and causing stratification or accumulation within the material bin 2, which would affect the uniformity of mixing. During discharge, the star-shaped unloader 3 opens, and the vibration support assembly 1 operates, causing the material bin 2 to begin vibrating discharge. This helps to loosen the material, promotes smooth discharge, improves the flowability of the material, and reduces the occurrence of blockages.

[0055] Regarding the specific structure of the vibration support assembly 1 in the above scheme:

[0056] See attached document Figure 1 As shown, the vibration support assembly 1 includes:

[0057] Mounting bracket 11, which serves to support the installation, is composed of multiple steel plates spliced ​​together.

[0058] The inner perforated plate 12 is mounted on the mounting bracket 11;

[0059] Spring 13, in multiple sets, is circumferentially arranged on the inner hole plate 12;

[0060] The fixed seat 14 is connected to the spring 13 and fixedly installed outside the material bin 2, and the bin body of the material bin 2 is connected to the hole of the inner perforated plate 12.

[0061] Vibration motor 15, there are two of them and they are installed on the material bin 2;

[0062] During the implementation of this solution, the vibration support assembly 1 is activated during the material feeding process. When the vibration motor 15 operates, it causes the material bin 2 to vibrate, thereby allowing the material to be fed smoothly into the material bin 2.

[0063] Regarding the specific structure of the rotary feed tube assembly 4 in the above scheme:

[0064] See attached document Figure 1 As shown, the rotary feed tube assembly 4 includes:

[0065] The vertical pipe 41 is vertically rotatably installed at the top center of the material bin 2, and its bottom end extends into the material bin 2 and is connected to the guide pipe 5.

[0066] The transmission part 42 is connected to the vertical tube 41;

[0067] The drive motor 43 is connected to the transmission part 42 so that the drive motor 43 operates to drive the vertical tube 41 to rotate synchronously.

[0068] Rotary joint 44 is connected to the top end of vertical pipe 41;

[0069] The feeding pipe 45 is connected to the rotary joint 44 and is connected to the external pneumatic conveying system during implementation;

[0070] In the implementation of this scheme, the drive motor 43 operates to drive the vertical pipe 41 to rotate, and then the guide pipe 5 performs an eccentric rotation in the material bin 2. During the rotation of the vertical pipe 41, due to the setting of the rotary joint, the feeding pipe 45 always remains stationary. After the material is fed through the feeding pipe 45, the material enters the guide pipe 5 along the vertical pipe 41, and finally achieves eccentric feeding through the guide pipe 5.

[0071] In the above scheme, considering the durability of material silo 2, therefore, refer to the appendix. Figure 2As shown:

[0072] The inner wall of the material silo 2 is provided with an anti-corrosion layer 21, which is made of stainless steel, fiberglass, etc.

[0073] In the above solution, considering the airtightness of material silo 2, therefore, refer to the appendix. Figure 3 As shown, a cementitious powder feeding device for mine backfilling also includes a sealing component 6; specifically, the sealing component 6 includes:

[0074] Telescopic cylinder 61 is horizontally mounted on mounting bracket 11;

[0075] The sealing plate 62 is connected to the telescopic end of the telescopic cylinder 61 and is fitted to the bottom of the star-shaped unloader 3. When storing material, it closes and blocks the bottom opening of the star-shaped unloader 3, and when discharging material, it opens the bottom opening of the star-shaped unloader 3.

[0076] The sealing valve 63 is installed on the feeding pipe 45 and is closed when storing materials and open when discharging materials.

[0077] During the implementation of this solution, the sealing plate 62 always seals and blocks the bottom opening of the star-shaped unloader 3 during the material storage process to prevent leakage and improve the sealing performance. Similarly, the sealing valve 63 always blocks the feed pipe 45 during the material storage process, which greatly improves the sealing effect.

[0078] To further prevent material stratification within material warehouse 2 in the above scheme, please refer to the appendix. Figure 4 As shown, a cementitious powder feeding device for mine backfilling also includes a mixing assembly 7. Specifically, the mixing assembly 7 includes:

[0079] There are two sets of stirring rods 71, which are horizontally rotatable inside the material bin 2, and one end of the stirring rod 71 extends to the outside of the material bin 2.

[0080] Transmission unit 2 72 is connected to two sets of stirring rods 71;

[0081] The transmission unit 3 73 is connected to one of the sets of stirring rods 71;

[0082] A stirring motor 74 is located outside the material silo 2 and connected to the transmission unit 73, so that the stirring motor 74 can drive the two sets of stirring rods 71 ​​to rotate.

[0083] During the implementation of this solution, the mixing component 7 uses periodic mixing to regularly mix the materials inside the material bin 2 to prevent stratification.

[0084] It is worth noting that in this utility model, the first transmission part 42, the second transmission part 72, and the third transmission part 73 can all adopt one or more of the existing belt drive, chain drive, or gear drive. This utility model will not elaborate on this.
