Description

Technical Field

[0001] The utility model relates to the technical field of heavy medium separators for coal separation, in particular to a shallow trough horizontal flow buffer tank that can be separately assembled. Background Technique

[0002] The heavy medium shallow trough separator is the main washing equipment for the heavy medium washing process. Its working principle is to inject a medium suspension with a certain density into the shallow trough tank body to perform physical flotation separation on raw coal. The light product (clean coal) flows into the lower-stage medium removal equipment along the overflow weir under the pushing action of the horizontal flow. The heavy product (gangue) settles to the bottom of the shallow trough tank body and is transported to the gangue medium removal equipment by a scraper driven by a chain to achieve the separation of raw coal. The horizontal flow buffer tank of the shallow trough separator is used to receive the medium suspension input by the horizontal flow pipeline. After the medium suspension is buffered in the horizontal flow buffer tank body, it uniformly transports the medium suspension to the shallow trough tank body along the length direction of the shallow trough tank. To achieve wear resistance, wear-resistant materials such as stainless steel plates or wear-resistant ceramic tiles are laid inside the horizontal flow buffer.

[0003] The outer frames of the existing horizontal flow buffer tanks of shallow trough separators are all approximately rectangular. Whether it is a domestic or imported shallow trough separator, one shallow trough is equipped with two horizontal flow buffer tanks, and one of the horizontal flow buffer tanks receives 5 medium suspension inlet pipes in the length direction. During use, due to factors such as the expansion of the medium suspension from the pipeline to the buffer tank body at the connection part between the horizontal flow buffer tank body and the inlet branch pipeline, and the change in flow velocity, this part is severely scoured and worn by the medium suspension, and the service life of the horizontal flow buffer tank is relatively low.

[0004] Currently, during the operation of the horizontal flow buffer tank, due to uneven wear, after wear occurs, either the entire horizontal flow buffer tank is replaced, or local external repairs are made. Replacing the entire buffer tank takes a long time for the operation and has too high a maintenance cost. Local external repairs not only affect the aesthetics of the equipment but also have a poor repair effect and a high repair frequency. Therefore, it is necessary to propose a shallow trough horizontal flow buffer tank that can be separately assembled to solve the above-mentioned problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a shallow trough horizontal flow buffer tank that can be separately assembled, which has the characteristics that according to the wear situation, the worn horizontal flow buffer tank can be quickly removed separately for independent repair or processing, and even replacement.

[0006] To achieve the above object, the present utility model provides the following technical solutions: A separable-assembled shallow-tank horizontal-flow buffer tank, comprising a split buffer tank, the split buffer tank including a plurality of horizontal-flow buffer tanks, the outer walls of the plurality of horizontal-flow buffer tanks being communicated with horizontal-flow branch pipes, connecting plates being installed on opposite sides of the plurality of horizontal-flow buffer tanks, and each two abutting connecting plates being connected by flange bolts.

[0007] To improve the strength of the horizontal-flow buffer tank, as a preferred embodiment of the separable-assembled shallow-tank horizontal-flow buffer tank of the present utility model, upper and lower sides of the outer walls of the plurality of horizontal-flow buffer tanks are fixedly connected with extension plates, and a plurality of reinforcing plates are fixedly connected between the upper end surface of the lower extension plate and the outer wall of the horizontal-flow buffer tank.

[0008] To connect the horizontal-flow branch pipes with the medium suspension feed main pipe, as a preferred embodiment of the separable-assembled shallow-tank horizontal-flow buffer tank of the present utility model, connection flanges are installed at the other ends of the horizontal-flow branch pipes.

[0009] To connect the split buffer tank with the shallow-tank separator equipment, as a preferred embodiment of the separable-assembled shallow-tank horizontal-flow buffer tank of the present utility model, mounting plates are fixedly connected to the upper end surfaces of the plurality of horizontal-flow buffer tanks.

[0010] To make the split buffer tank maintain aesthetics, as a preferred embodiment of the separable-assembled shallow-tank horizontal-flow buffer tank of the present utility model, the plurality of horizontal-flow buffer tanks are of the same size.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] The present utility model first processes the horizontal-flow buffer tank into a split-assembly form, with one horizontal-flow branch pipe corresponding to one independent horizontal-flow buffer tank, and adjacent two horizontal-flow buffer tanks can be connected through connecting plates and flange bolts. Furthermore, through the independent and split-assembled horizontal-flow buffer tanks, the replacement operation time can be shortened and the maintenance quality can be ensured. Compared with the integral horizontal-flow buffer tank, the maintenance cost is low. Thus, according to the wear condition, the worn horizontal-flow buffer tank can be quickly removed separately for independent repair or processing, or even replacement.

[0017] Please refer to Figures 1 to 3 , a shallow groove horizontal flow buffer tank that can be assembled separately, including a split buffer tank 1. The split buffer tank 1 includes a plurality of horizontal flow buffer tanks 101. Horizontal flow branch pipes 3 are communicated with the outer walls of the plurality of horizontal flow buffer tanks 101. Connecting plates 102 are installed on opposite sides of the plurality of horizontal flow buffer tanks 101. Flange bolts are used to connect between every two abutting connecting plates 102.

[0018] In this embodiment: The horizontal flow buffer tank 101 is processed into a split assembly form. One horizontal flow branch pipe 3 corresponds to an independent horizontal flow buffer tank 101. Adjacent two horizontal flow buffer tanks 101 can be connected through the connecting plate 102 and flange bolts. Furthermore, the independent and split-assembled horizontal flow buffer tanks 101 can not only shorten the replacement operation time but also ensure the maintenance quality. Compared with the integral horizontal flow buffer tank 101, the maintenance cost is low. Thus, according to the wear condition, the worn horizontal flow buffer tank 101 can be quickly removed separately for independent repair or processing, or even replacement.

[0019] As a technical optimization scheme of the present utility model, extension plates 4 are fixedly connected to the upper and lower sides of the outer walls of the plurality of horizontal flow buffer tanks 101. A plurality of reinforcing plates 401 are fixedly connected between the upper end surface of the lower extension plate 4 and the outer wall of the horizontal flow buffer tank 101.

[0020] In this embodiment: The strength of the horizontal flow buffer tank 101 can be improved through the extension plate 4 and the reinforcing plate 401.

[0021] As a technical optimization scheme of the present utility model, connecting flanges are installed at the other ends of the horizontal flow branch pipes 3.

[0022] In this embodiment: The horizontal flow branch pipes 3 can be connected to the main medium suspension feed pipe through the connecting flanges, thereby ensuring the smooth entry of the medium suspension into the horizontal flow branch pipes 3.

[0023] As a technical optimization scheme of the present utility model, mounting plates 2 are fixedly connected to the upper end surfaces of the plurality of horizontal flow buffer tanks 101.

[0024] In this embodiment: The split buffer tank 1 can be connected to the shallow groove separator equipment through the mounting plate 2.

[0025] As a technical optimization scheme of the present utility model, the sizes of the plurality of horizontal flow buffer tanks 101 are the same.

[0026] In this embodiment, since the sizes of the multiple horizontal flow buffer tanks 101 are the same, the split buffer tank 1 can maintain its aesthetic appearance.

[0027] Working principle: First, the horizontally assembled horizontal flow buffer tank 101 is the same as the integrally assembled buffer tank in terms of process performance, and both can achieve balanced and stable supply of the medium suspension along the length direction of the shallow tank separator without affecting the normal use of the shallow tank separator. Specifically, the horizontal flow buffer tank 101 is processed into a split assembly form, with one horizontal flow branch pipe 3 corresponding to one independent horizontal flow buffer tank 101, and adjacent two horizontal flow buffer tanks 101 can be connected through the connecting plate 102 and flange bolts. Furthermore, the independent and split-assembled horizontal flow buffer tank 101 can not only shorten the replacement operation time but also ensure the maintenance quality. Compared with the integral horizontal flow buffer tank 101, the maintenance cost is low. Therefore, according to the wear condition, the worn horizontal flow buffer tank 101 can be quickly removed separately for independent repair or processing, or even replaced.

[0028] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
