Description

Technical Field

[0001] This utility model relates to the field of emulsion recovery, and in particular to an emulsion collection device for a single hydraulic support. Background Technology

[0002] Currently, waste emulsion from single hydraulic props is collected using a homemade, simple plastic bucket. A round hole is cut into the bucket, just large enough to insert a three-way valve. When the single hydraulic prop is depressurized, one person holds the plastic bucket against the three-way valve, while another person depressurizes the prop. The waste emulsion then enters the plastic bucket through the round hole for collection.

[0003] The initial support force of a single hydraulic prop is greater than or equal to 11.4 MPa. When the single hydraulic prop is depressurized, the emulsion of the three-way valve has a large instantaneous impact force, which can easily cause it to fall off and pose a risk of injury. Moreover, it is not easy to fix during use and requires a special person to hold it. Utility Model Content

[0004] This invention proposes a single hydraulic prop emulsion collection device, which enables convenient recycling without external leakage and prevents the emulsion from flowing into the ground and polluting the environment.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A single hydraulic prop emulsion collection device, comprising:

[0007] An inverted L-shaped steel pipe, comprising a horizontal portion and a vertical portion, wherein the horizontal portion has a connector for connection to a single hydraulic prop three-way valve;

[0012] Preferably, in the single hydraulic support emulsion collection device, the outer side of the vertical part is provided with an outer sealing ring and a groove.

[0013] Preferably, in the single hydraulic support emulsion collection device,

[0014] The emulsion filter box is provided with a threaded connection port at the top for connection to the bottom of the vertical part;

[0015] The emulsion filter box is equipped with a first filter screen and a second filter screen. The first filter screen and the second filter screen are tilted in opposite directions, and the first filter screen and the second filter screen divide the emulsion filter box into three emulsion collection chambers. The three emulsion collection chambers are respectively connected to three independent emulsion collection tanks through collection pipes.

[0016] Preferably, in the single hydraulic support emulsion collection device,

[0020] The beneficial effects of this utility model are as follows:

[0021] Compared with existing devices, this utility model adopts a rigid connection with the single hydraulic support three-way valve, so the device will not shake when collecting emulsion and does not require a special person to hold it.

[0022] The inner sealing ring can fit against the outer surface of the three-way valve core, thus preventing the emulsion from leaking out.

[0023] If the tube length is insufficient, the slot and outer sealing ring can be used to connect a high-pressure hose to extend it. Attached Figure Description

[0024] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

[0025] Figure 1 This is a schematic diagram of one embodiment of the hydraulic control valve for coal mine longwall faces provided by this utility model. Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] The technical challenge of this invention lies in the fact that when the single support column is depressurized, the device will be knocked off by the impact of the high-pressure emulsion, and the connection between the device and the single support column must be changed; when the single support column is depressurized, the emulsion will leak.

[0028] like Figure 1 As shown, this utility model provides a single hydraulic support emulsion collection device, which includes:

[0029] An inverted L-shaped steel pipe 1, comprising a horizontal portion and a vertical portion, wherein the horizontal portion has a plug-in interface 11 for connection to a single hydraulic prop three-way valve 2;

[0030] A retaining ring 3 is threadedly connected to the horizontal portion, and a blind hole is provided on the upper and lower parts of the outer periphery of the retaining ring 3, and the blind hole is respectively connected to the two end faces of the retaining ring to form a pin hole;

[0031] Two mounting pieces 4 are respectively connected to the blind hole pin, and the inner side of the mounting piece 4 is hinged with a semi-circular clamp 5 to fix it to the single hydraulic support 6;

[0032] And the emulsion filter box 7, whose seal is located below the vertical section.

[0033] The combined effect of the connector, retaining ring, mounting parts, and semi-circular clamps ensures a stable connection between the entire device and the individual hydraulic support, preventing it from loosening or falling off due to the impact of high-pressure emulsion.

[0034] In one embodiment of the single hydraulic prop emulsion collection device provided by this utility model, an inner sealing ring 12 is provided on the inner wall of the insertion port 11 to improve the sealing between the inverted L-shaped steel pipe and the three-way valve and prevent emulsion loss.

[0035] In one embodiment of the single hydraulic support emulsion collection device provided by this utility model, the outer side of the vertical part is provided with an outer sealing ring 13 and a groove 14, which can be connected to an extended rubber tube when space is insufficient, making it convenient to connect to the emulsion filter box.

The first filter screen 71 and the second filter screen 72 are tilted in opposite directions, and the first filter screen 71 and the second filter screen 72 divide the emulsion filter box 7 into three emulsion collection chambers. The three emulsion collection chambers are respectively connected to three independent emulsion collection tanks 8 through collection pipes.

[0039] The first and second filters can be set with different pore diameters to achieve a stepwise filtration effect, and the emulsions are collected into three emulsion collection tanks respectively, which facilitates the subsequent recycling and reuse of the emulsions.

[0040] In one embodiment of the single hydraulic prop emulsion collection device provided by this utility model,

[0041] The semi-circular clamp 5 has a connecting part at its end, and a first connecting hole is provided on the connecting part;

[0042] A connecting plate 9 is disposed between the two mounting parts 4, and the two ends of the connecting plate 9 are provided with second connecting holes corresponding to the first connecting hole;

[0043] Two fasteners pass through the first connecting hole and the second connecting hole respectively to fix the semi-circular clamp 5 to the single hydraulic support 6.

[0044] This makes the connection between the device and the individual hydraulic support more secure.

[0045] This invention is easy to carry and simple to operate. It can be extended by connecting a high-pressure hose, and can ensure that there is no leakage of emulsion during recycling, with a recycling rate of almost 100%.

[0046] The present invention has the following features: 1. The retaining ring and the three-way valve are rigidly connected.

[0047] 2. The sealing ring inside the connector can achieve a tight fit with the outer surface of the three-way valve core to prevent emulsion leakage.

[0048] 3. The bend in the pipe can prevent the impact caused by the instantaneous high pressure of the emulsion.

[0049] 4. If the length cannot meet the actual needs, the high-pressure hose can be extended by using a slot and an outer sealing ring.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
