Description

Technical Field

[0001] The utility model relates to the technical field of tailing treatment of aggregates, and particularly relates to an aggregate tailing treatment device. Background Art

[0002] Aggregates use limestone ore as raw materials and are generally attached with soil (siliceous raw materials). After the original stones are crushed by a crusher, the mixture of crushed stones (with a diameter of 0 - 5 mm) and soil enters the external discharge yard after being screened by a mud removal vibrating screen. The mixture entering the external discharge yard becomes tailing waste and is discarded because the mud content is too high to meet the national standard of aggregates. Generally, it accounts for 20% of the total output. If this part of the aggregate tailings can be recycled, the production cost will be greatly reduced. Therefore, probability screens are often used in the industry to process tailings, and the aggregates (with a diameter of 2 - 5 mm) rich in them are screened out to be used as raw materials for manufactured sand production or directly screened into materials meeting the manufactured sand standard for sale.

[0003] However, during the process of screening aggregate tailings using a probability screen, due to the large water content and a large amount of soil in the aggregate tailings, it is extremely easy to cause blockage of the screen mesh. It is necessary to stop the machine in time and disassemble the machine to clear the blockage, which takes a long time, consumes a large amount of manpower, and reduces the overall screening efficiency.

[0004] Therefore, this application specifically proposes an aggregate tailing treatment device to solve the above technical problems. Content of the Utility Model

[0005] The main purpose of the utility model is to solve the above deficiencies, provide an aggregate tailing treatment device, realize automatic blockage clearing without stopping the machine, avoid the impact on production efficiency caused by stopping the machine, and also avoid the manpower loss caused by manual blockage clearing.

[0006] To solve the above technical problems, the utility model adopts the following technical solutions:

[0007] An aggregate tailing treatment device includes a support base and a probability screen erected on the top of the support base, and further includes: a bracket, fixedly arranged on the support base and located on one side of the probability screen; an air storage tank, fixedly arranged on the top of the bracket and externally connected to a compressed air source; a plurality of pulse solenoid valves, arranged in a straight line and evenly distributed on the air storage tank and communicated with the air storage tank; a blowing component, connected to the air outlet of the pulse solenoid valve and inserted into the inner cavity of the probability screen from the top of the probability screen.

[0008] Further, the blowing component includes a compressed air pipeline connected to the air outlet of the pulse solenoid valve and a plurality of spray pipes evenly distributed on the compressed air pipeline and inserted into the inner cavity of the probability screen.

[0009] Furthermore, the compressed air pipelines are parallel to each other and to the upper cover plate of the probability screen, and the nozzle is perpendicular to the upper cover plate.

[0010] Furthermore, the upper cover plate is provided with an insertion hole for inserting the nozzle, and the diameter of the insertion hole is larger than the diameter of the nozzle.

[0011] Furthermore, the spray assembly also includes a mounting ring fixedly arranged on the outer wall of the nozzle and a bellows sleeved on the nozzle, with both ends respectively sealedly connected to the mounting ring and the top surface of the upper cover plate.

[0012] Furthermore, the pulse solenoid valve is connected to a pulse controller.

[0013] The beneficial effects of the utility model are embodied in:

[0014] 1. The utility model sets an air storage tank, a pulse solenoid valve and a spraying assembly, and uses a pulse controller to preset the switching frequency of the pulse solenoid valve and the switching sequence of different pulse solenoid valves and other parameters, so that different pulse solenoid valves are opened in sequence with the same switching frequency. When a single pulse solenoid valve is opened, the compressed air in the air storage tank is transported to each nozzle via a compressed air pipeline and sprayed into the inner cavity of the probability screen. The high-speed jet of compressed air impacts each layer of probability screen in the probability screen. In addition, the mesh of the probability screen has the characteristic of a certain deformation and expansion amount. The mud and other blockages on the probability screen are easily washed off by the compressed air. The pulse solenoid valves are switched on and off in sequence, and each layer of the probability screen is periodically cleared in sequence, thereby avoiding the blockage of the probability screen without frequent shutdown and manual clearing.

[0015] 2. The utility model provides a separate support for the air storage tank by arranging a bracket, and arranges a blowing assembly consisting of a compressed air pipe, a nozzle, a mounting ring and a bellows. The nozzle inserted into the probability screen does not contact the probability screen, so that core components such as the pulse solenoid valve do not vibrate with the probability screen during the vibration of the probability screen, thereby improving the overall service life of the device.

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Without conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figures 1-4 shown, the present utility model provides an aggregate tailing treatment device, including a support base 1 and a probability sieve 2 erected on the top of the support base 1, and further including:

[0024] A bracket 3, fixedly arranged on the support base 1 and located on one side of the probability sieve 2;

[0025] A gas storage tank 4, fixedly arranged on the top of the bracket 3 and externally connected to a compressed air source;

[0026] A plurality of pulse solenoid valves 5, arranged in a straight line and evenly distributed on the gas storage tank 4 and communicated with the gas storage tank 4;

[0027] An injection assembly 6, connected to the air outlet of the pulse solenoid valve 5 and inserted into its inner cavity from the top of the probability sieve 2.

[0028] When in use, first use the pulse controller to preset the switching frequency of the pulse solenoid valve 5 and the switching sequence of different pulse solenoid valves 5 and other parameters, so that different pulse solenoid valves 5 are opened in sequence with the same switching frequency. When a single pulse solenoid valve 5 is opened, the compressed air in the air storage tank 4 enters the compressed air pipe 61, and is further sprayed into the inner cavity of the probability screen 2 through each nozzle 62. The high-speed jet of compressed air impacts each layer of probability screen in the probability screen 2. In addition, the probability screen mesh has the characteristic of a certain deformation and expansion amount. Therefore, mud and other blockages on the probability screen can be easily directly washed off by compressed air. Each pulse solenoid valve 5 is cyclically switched on and off in sequence, and each layer of the probability screen is periodically cleared in sequence, thereby avoiding blockage of the probability screen without frequent shutdown and manual clearing.

[0029] In one embodiment, the spray assembly 6 includes a compressed air pipeline 61 connected to the air outlet of the pulse solenoid valve 5 and a plurality of spray pipes 62 evenly arranged on the compressed air pipeline 61 and inserted into the inner cavity of the probability screen 2 .

[0030] With this design, the compressed air ejected from the air outlet of the pulse solenoid valve 5 is transported through the compressed air pipeline 61 and enters each nozzle 62. The densely distributed nozzles 62 allow the compressed air to be sprayed at a higher pressure to various locations on the probability screen, thereby avoiding dead corners on the probability screen that cannot be cleared.

[0031] In one embodiment, the compressed air pipes 61 are parallel to each other and to the upper cover plate 7 of the probability screen 2 , and the nozzles 62 are perpendicular to the upper cover plate 7 .

[0032] With this design, the compressed air ejected from the nozzle 62 can vertically impact the mesh surface of the probability screen in the probability screen 2, making it easier to flush out the blockage on the screen.

[0033] In one embodiment, a plug hole 8 for inserting the nozzle 62 is formed on the upper cover plate 7 , and the diameter of the plug hole 8 is larger than the diameter of the nozzle 62 .

[0034] Since the probability screen 2 will vibrate violently during operation, the nozzle 62 is designed not to contact the probability screen 2 during operation. In addition, the air tank 4 is fixed by the bracket 3 and does not contact the probability screen 2, so that the pulse solenoid valve 5 does not have to vibrate with the probability screen 2, thereby ensuring that the pulse solenoid valve 5 has a good working environment and increasing its service life.

[0035] In one embodiment, the spray assembly 6 further includes a mounting ring 63 fixedly mounted on the outer wall of the nozzle 62 and a bellows 64 sleeved on the nozzle 62 and having two ends sealedly connected to the mounting ring 63 and the top surface of the upper cover plate 7 respectively.

[0036] With such a design, it is ensured that the nozzle 62 is in a sealed connection state with the probability sieve 2, preventing the aggregate and dust from overflowing from the gap between the nozzle 62 and the jack 8 of the probability sieve 2.

[0037] In one embodiment, the pulse solenoid valve 5 is connected to a pulse controller.

[0038] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.

[0039] It should be noted that if there are directional indications (such as up, down, left, right, front, back...) involved in the embodiments of the present utility model, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a certain specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0040] In addition, "a plurality of" means two or more. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.
