Description

Technical Field

[0001] The utility model relates to the technical field of material separation, in particular to a water jet self-cleaning separation device. Background Art

[0002] At present, the wastewater generated during the production and life in coal mines is collected by drainage channels to the water tank. The residues dropped during the underground transportation of coal slime are manually cleaned and collected in the drainage channels, causing the solid deposition of coal slime and other solid phases in the water tank in a short time, which requires frequent cleaning of the solid phase deposition in the water tank.

[0003] In addition, with regard to the recycling of waste at the tail end of the coal washing plant, a portion of the clean coal and ash gangue powder will be mixed together in the process of coal washing. The existing technology is to add chemicals to this part of the waste, flocculate and filter it, and then use it as roadbed filling, etc., which causes a waste of clean coal and cannot generate economic value. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art and provide a water jet self-cleaning separation device. The materials mixed with clean coal and ash gangue powder are conveniently extracted through the joint action of the spraying mechanism, the separation mechanism and the liquid phase collecting mechanism, thereby generating greater economic value. At the same time, the water jet self-cleaning separation device can also be used for purification of various branch drainage channels in coal mines before they are merged into the water tank, which can effectively reduce solid phase deposition in the water tank, improve the use efficiency of the water tank, and greatly reduce the burden of underground operations.

[0005] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a water jet self-cleaning separation device, comprising a material guide trough, a spraying mechanism, a separation mechanism and a liquid phase collection mechanism, with the feeding direction as the rear and the discharging direction as the front;

[0006] The material guide trough is arranged at the rear end of the liquid phase collecting mechanism, and the material enters the separation mechanism through the material guide trough. The spraying mechanism, the separation mechanism and the liquid phase collecting mechanism are arranged in sequence from top to bottom;

[0007] The separation mechanism comprises a screen and a guide rail for screening materials, and the spray mechanism reciprocates linearly forward and backward along the guide rail;

[0008] The spray mechanism comprises a spray pipe, on which a plurality of evenly distributed nozzles are arranged, and the nozzles are used for cleaning and pushing forward the material on the screen.

[0009] As an improvement of the utility model, the separation mechanism further includes a support frame II, a rodless cylinder and a guide rail slider;

[0010] The rodless cylinder and the guide rail slider are respectively arranged on both sides of the support frame II. The rodless cylinder provides a power source for the spray mechanism, and the guide rail slider ensures that the spray mechanism does not get stuck when performing reciprocating linear motion.

[0011] Both sides of the support frame II are provided with material blocking plates.

[0012] As an improvement of the utility model, the spray mechanism further comprises a support frame I, and the spray pipe is installed on the support frame I;

[0013] The support frame I is provided with four directional wheels for supporting the spray mechanism, and the directional wheels are placed on the support frame II.

[0014] As an improvement of the utility model, the spray pipe is composed of an upper spray pipe and a lower spray pipe arranged below the upper spray pipe, and the lower spray pipe is provided with a plurality of evenly distributed nozzles.

[0015] As an improvement of the utility model, the spraying pressure of the spraying pipe is 0.2MPa-0.5MPa, and the inclination angle between the screen and the horizontal plane is 2°-6°.

[0016] As an improvement of the utility model, the nozzle is a spherical tangent nozzle, and the angle between the nozzle and the screen is 60° to 75°.

[0017] The beneficial effects of the utility model are as follows: a water jet self-cleaning separation device, the material of clean coal and ash gangue powder mixed together can be conveniently extracted from the mixed material by the spraying mechanism, the separation mechanism and the liquid phase collection mechanism. Taking a coal washing plant with an annual output of 3 million tons as an example, it can generate nearly 3 million profits, with outstanding economic value, and realize resource recycling. At the same time, the water jet self-cleaning separation device can also be used for purification treatment of various branch drainage channels in coal mines before they merge into the water tank, which can effectively reduce solid phase deposition in the water tank, improve the use efficiency of the water tank, and greatly reduce the burden of underground operations. It has a simple structure, convenient operation, safety, reliability and environmental protection.

[0018] Furthermore, the spray pipe is composed of an upper spray pipe and a lower spray pipe arranged below the upper spray pipe. Through the design of the upper and lower spray pipes, the nozzles on the upper spray pipe are used to clean and push the clean coal on the screen, and the nozzles on the lower spray pipe are used to clean the materials on the screen and to unblock the materials blocked in the middle of the screen. The two together ensure that the coal powder at the front end of the screen meets the standard requirements of clean coal, with a simple structure and excellent treatment effect.

[0019] Furthermore, the spray pressure of the spray pipe is 0.2MPa~0.5MPa, and the inclination angle between the screen and the horizontal plane is 2°~6°. If the spray pressure is too small, it cannot play a good role in pushing the clean coal on the screen forward. If the pressure is too large, the splashing is serious, and it causes a waste of water resources and even penetrates the screen. If the inclination angle between the screen and the horizontal plane is too small, the material on the screen will flow backwards. If the inclination angle is too large, the material on the screen will flow forward too fast, which will make it impossible to separate the ash, and the moisture content of the front-end material is high. Through the above design, the clean coal can be extracted efficiently while saving water resources and ensuring the safety of the screen.

[0020] Furthermore, the nozzle is a spherical tangent nozzle, and the angle between the nozzle and the screen is 60° to 75°. Through the above design, in the working process, in addition to ensuring that the clean coal can be pushed forward normally, the ash can also be fully cleaned out, so that the screening effect and extraction efficiency of the clean coal can reach the best state.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be interpreted as limiting the present invention.

[0028] It should be noted that the directional terms such as front, back, up, down, top, bottom, etc. in the embodiments of the present invention are merely relative concepts or are based on the normal use status of the product and should not be considered as restrictive.

[0029] like Figure 1 As shown, a water jet self-cleaning separation device includes a material guide trough 1, a spray mechanism 2, a separation mechanism 3 and a liquid phase collecting mechanism 4, with the feeding direction as the rear and the discharging direction as the front. The material guide trough 1 is arranged at the rear end of the liquid phase collecting mechanism 4, and the material enters the separation mechanism 3 through the material guide trough 1. The spray mechanism 2, the separation mechanism 3 and the liquid phase collecting mechanism 4 are arranged in sequence from top to bottom.

[0030] like Figure 2 As shown, the guide trough 1 comprises a feed port 11 and a guide plate Ⅰ 13. External coal slurry water enters the screen 32 of the separation mechanism through the feed port 11 and the guide plate Ⅰ 13. Two cleaning holes 12 are provided on the top of the guide trough 1. When coal slurry is deposited inside the guide trough 1, they can be opened for cleaning.

[0031] The liquid phase collecting mechanism 4 includes a liquid phase collecting tank 41 and a support frame III 45. The liquid phase collecting tank 41 is installed in the support frame III 45 and is used to collect the liquid separated by the screen 32. The top four corners of the liquid phase collecting tank 41 are respectively provided with support frame III connecting parts 42, and the bottom is provided with a forklift groove 44 to facilitate the transportation of a forklift. A drain port 43 is provided at the bottom of one side of the liquid phase collecting tank 41. The above-mentioned guide trough 1 is installed at the rear end of the support frame III 45 through the guide trough support frame 5.

[0032] like Figure 3 and Figure 4As shown, the separation mechanism 3 includes a screen 32 for screening materials, a guide rail 38, a support frame II 34 and a rodless cylinder 37. The guide rail 38 is provided with a guide rail slider 39. The rodless cylinder 37 and the guide rail slider 39 are respectively arranged on both sides of the support frame II 34. The rodless cylinder 37 provides a power source for the spray mechanism 2 through the cylinder slider 371. The guide rail slider 39 ensures that the spray mechanism 2 does not get stuck when performing reciprocating linear motion. The support frame II 34 is provided with a baffle plate 36 on both sides. The baffle plates 36 on both sides are mainly used to collect the spray splashed coal slurry water generated during the working process and guide it into the liquid phase collection tank 41. The four corners of the bottom of the support frame II 34 are respectively provided with a support frame II connection part 35, and the support frame II connection part 35 is connected to the support frame III connection part 42 by bolts. The screen 32 is installed in the support frame II34. The rear end of the screen 32 is provided with a guide plate II31, and the front end of the screen 32 is provided with a guide plate III33. The external coal slurry water enters the screen 32 for screening through the guide trough 1 and the guide plate II31 in sequence. The screened liquid phase falls into the liquid phase collection tank 41 below it, and its solid phase is cleaned and pushed forward under the action of the spray mechanism 2. The finally separated clean coal is collected through the guide plate III33.

[0033] like Figure 5 As shown, the spray mechanism 2 includes a support frame Ⅰ21, an upper spray pipe 23 and a lower spray pipe 25. The upper spray pipe 23 and the lower spray pipe 25 are both installed on the support frame Ⅰ21. The support frame Ⅰ21 is connected to the rodless cylinder 37 and the guide rail slider 39 on the support frame Ⅱ34. Preferably, the connection method adopts a detachable bolt connection. Four directional wheels 26 for supporting the spray mechanism 2 are provided on the support frame Ⅰ21. The directional wheels 26 are placed on the support frame Ⅱ34. The reciprocating motion of the spray mechanism 2 is ensured by the four directional wheels 26. Preferably, four auxiliary wheels 24 are also provided on both sides of the support frame Ⅰ21, which cooperate with the upper crossbeam of the support frame Ⅱ34 to mainly ensure that the spray mechanism 2 always moves in a straight line during the reciprocating motion. Two anti-splash plates 22 are also provided on both sides of the support frame Ⅰ21 to prevent the coal slurry water splashed by the spray from splashing to the outside of the device to avoid environmental pollution.

[0034] The upper spray pipe 23 and the lower spray pipe 25 are both provided with a number of uniformly distributed nozzles. Preferably, the spray pressure of the upper spray pipe 23 and the lower spray pipe 25 is 0.2MPa-0.5MPa, the inclination angle between the screen 32 and the horizontal plane is 2°-6°, and the screen 32 is inclined from the back to the front, that is, the rear end height of the screen 32 is higher than the front end height. If the spray pressure is too small, the clean coal on the screen 32 cannot be pushed forward well. If the pressure is too large, the splashing is serious, and water resources are wasted, and the screen 32 may even be penetrated. If the inclination angle between the screen 32 and the horizontal plane is too small, the material on the screen 32 will flow backwards. If the inclination angle is too large, the material on the screen 32 will flow forward too fast, which will make it impossible to separate the ash, and the moisture content of the front material is high. Through the above design, the clean coal can be extracted efficiently under the premise of saving water resources and ensuring the safety of the screen 32. Preferably, the nozzle is a spherical tangent nozzle, and the angle between the nozzle and the screen 32 is 60° to 75°. Through the above design, in the working process, in addition to ensuring that the clean coal can be pushed forward normally, the ash can also be fully cleaned out, so that the screening effect and extraction efficiency of the clean coal can reach the best state.

[0035] The working principle of the utility model is as follows: when extracting clean coal, firstly, the rodless cylinder is operated, and driven by the cylinder slider 371, the spray mechanism 2 is made to make a reciprocating linear motion in the front-to-back direction, and the upper spray pipe 23 and the lower spray pipe 25 are opened at the same time; secondly, the coal slurry water is sequentially passed through the feed port 11, the guide trough 1, the guide plate I13 and the guide plate II31 to the screen 32; finally, the ash and water on the screen 32 are separated into the liquid phase collection tank 41 below the screen 32 by the linear reciprocating motion of the spray mechanism 2, and the clean coal on the screen 32 is pushed into the guide plate III33 at the front end of the screen for recycling.

[0036] It should be noted that when the utility model is used to extract clean coal, 1% to 3% of clean coal can be conveniently extracted from a mixture of part of the clean coal and ash gangue powder. Taking a coal washing plant with an annual output of 3 million tons as an example, it can generate nearly 3 million in profits, with outstanding economic value, and realize resource recycling. At the same time, the utility model can also be used for purification treatment of various branch drainage channels in coal mines before they merge into the water tank, which can effectively reduce solid phase deposition in the water tank, improve the use efficiency of the water tank, and greatly reduce the burden of underground operations. It has a simple structure, is easy to operate, safe, reliable and environmentally friendly.

[0037] The above is a detailed introduction to a water jet self-cleaning separation device provided by the utility model. Specific examples are used in this article to illustrate the structural principles and implementation methods of the utility model. The above embodiments are only used to help understand the method and core ideas of the utility model; at the same time, for general technicians in this field, according to the ideas of the utility model, there will be changes in the specific implementation methods and application scopes.
