Description

Technical Field

[0001] The present invention relates to the technical field of material mixing, and more specifically, to a two-component polymer foam material mixing pipe applied to roadway construction. Background Art

[0002] Under the background of improving the safety production standard in the mining industry, the roadway spraying engineering technology has been widely applied and emphasized; this technology has been widely used in the fields of mine fire prevention, roadway support, tunnel leak stoppage, temporary support, slope support, etc., which can not only improve the stability of the surrounding rock mass, but also effectively extend its service life; especially in the field of roadway spraying, the application of two-component polymer foam materials is becoming increasingly widespread, and such materials have shown extremely effective performance in the fields of mine structure reinforcement and fireproof plugging.

[0003] During the process of roadway construction spraying, uneven mixing will cause uneven coating performance, resulting in poor support and protection effects, such as peeling and cracking; the construction progress will be delayed, the cost will increase; the safety hazards will increase, toxic gases are likely to leak, and the roof is likely to fall; the working environment will deteriorate, the dust pollution will be serious, and the construction difficulty will also increase accordingly. Sufficiently mixing the two chemical components to ensure that the material reaches the best performance is the prerequisite for using such foam materials for spraying; therefore, in order to meet the needs of mine support and fire prevention, and achieve the purpose of high universality and good safety, it is particularly crucial to develop a new type of two-component polymer foam material mixing pipe applied to roadway construction:

[0004] However, during the use of the existing two-component polymer foam material mixing pipes applied to roadway construction, the mixing efficiency is low, and different components cannot be quickly and effectively mixed. Moreover, the equipment structure is single. For different construction scenarios and mixing ratios, the equipment needs to be replaced, and it cannot effectively adapt to the changing needs of different working conditions. At the same time, in the same working condition, it cannot effectively cope with the occurrence of special situations such as partial unevenness and serious water leakage in the roadway, resulting in low applicability during use, and thus affecting the later spraying effect. Summary of the Invention

[0005] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide a two-component polymer foam material mixing pipe applied to roadway construction, which can improve the mixing efficiency of the spraying material during use, ensure that the two-component material can be initially shunted, cross-mixed and reversely swirling, and further strengthen the mixing through orifice plate design, thereby significantly improving the uniformity and performance of the material.

[0019] The present invention is further configured such that: a first limiting mixing orifice plate is fixed to the inner wall of the orifice plate mixing pipe housing, a second limiting mixing orifice plate is fixed to the inner wall of the orifice plate mixing pipe housing on the side away from the first limiting mixing orifice plate, a number of orifice plate connecting rods are fixed between the first limiting mixing orifice plate and the second limiting mixing orifice plate, and a number of mixing orifice plates are equidistantly arranged between the first limiting mixing orifice plate and the second limiting mixing orifice plate, and the number of mixing orifice plates is fixedly connected to the number of orifice plate connecting rods.

[0020] The advantages of the present invention are as follows:

[0021] (1) Under the action of the pneumatic operation equipment in the present invention, the spraying material is mixed and rapidly flows in the self - driving pipeline, driving the sliding cylinder and the two stirring propellers fixed to the inner wall of the sliding cylinder to rotate and reciprocate on the circumferential side of the connecting column, thereby preliminarily mixing the spraying material that has initially passed through the second internal transition pipe, enabling the spraying material to be preliminarily mixed, thus preliminarily improving the uniformity and performance of the spraying material, and further improving the later spraying effect.

[0022] (2)During the use of the present invention, the preliminarily mixed spraying material passes through the spiral blades and reverse spiral blades arranged inside the housing of the spiral blade mixing pipeline, thereby further mixing the spraying material, enabling the spraying material to be shunted, cross-mixed, and reverse-swirl during flow, and combining with the edge flow holes sequentially arranged on one side of the spiral blades and reverse spiral blades, so that the spraying material entering the housing of the spiral blade mixing pipeline can also flow smoothly. The entire housing of the spiral blade mixing pipeline is slightly larger than other pipelines, further improving the mixing effect of the spraying material inside the housing of the spiral blade mixing pipeline.

[0023] (3)During the use of the present invention, the further mixed spraying material enters the housing of the orifice plate mixing pipeline for final mixing. After the spraying material enters the housing of the orifice plate mixing pipeline, the housing of the orifice plate mixing pipeline can protect the internal structure and allow the spraying material to flow through. The first limit mixing orifice plate, mixing orifice plate, and second limit mixing orifice plate are the main structures of the housing of the orifice plate mixing pipeline, which play a role in finally mixing the spraying material, making the spraying material more uniformly mixed.

[0043] A two-component polymer foam material mixing pipe applied to roadway construction. Specifically, it includes a feed pipe assembly 1, and one end of the feed pipe assembly 1 is fixedly connected to a mixing assembly 2; the feed pipe assembly 1 includes a feed member 3, and a mixing member 4 is fixedly inserted inside the feed member 3; the feed member 3 includes a self-driven mixing pipe 301, two symmetric and equal-proportion mixing pipes 302 are communicated and arranged on the outer peripheral side of the self-driven mixing pipe 301, one end of the self-driven mixing pipe 301 is communicated with a first external transition pipe 303, a first internal transition pipe 304 is communicated and arranged on the inner wall of the first external transition pipe 303, one end of the first internal transition pipe 304 is located inside the first external transition pipe 303 and is communicated with a second internal transition pipe 305, and a first connection flange 306 fixedly connected to the mixing member 4 is fixed at one end of the first external transition pipe 303; a self-driven chamber 3012 is arranged on the inner wall of the self-driven mixing pipe 301, a self-driven pressure booster 3011, an impeller seat 3013, and a deflector 3015 are sequentially arranged inside the self-driven chamber 3012, and an impeller 3014 is installed in the impeller seat 3013; the mixing member 4 includes a connecting plate 401 inserted and fixed inside the first connection flange 306, a connecting column 402 is fixed at the center position on one side of the connecting plate 401, a first spring 403 sleeved and matched with the peripheral side of the connecting column 402 is fixed on one side of the connecting plate 401, a first sliding ring 404 slidably matched with the connecting column 402 is fixed at one end of the first spring 403, a sliding cylinder 408 is slidably matched with the peripheral side of the connecting column 402, a sliding cylinder 405 slidably matched with the connecting column 402 is fixedly connected to one end of the sliding cylinder 408, a plurality of turbine fan blades 406 are fixed on the peripheral side of the sliding cylinder 405, and two symmetric stirring propellers 407 are fixed on the inner wall of the sliding cylinder 405; a limit nut 409 is threadedly connected to one end of the connecting column 402 located inside the sliding cylinder 405, a second spring 410 sleeved and matched with the peripheral side of the connecting column 402 is fixed on one side of the limit nut 409, and a second sliding ring 411 slidably matched with the connecting column 402 is fixed at one end of the second spring 410.

[0044] The specific application of the first embodiment is as follows: When this hybrid pipeline is used for spraying operations on a roadway that has been cleaned to remove loose rocks, dust, and moisture, when the spraying material passes through the self-driven hybrid pipeline 301, the materials located inside the pipeline, under the action of the wind pressure and the flow force of the materials themselves, pass through the self-driven pressure booster 3011 provided on the inner wall of the self-driven chamber 3012 (the structure of the self-driven pressure booster 3011 is the internal structure of the self-driven hybrid pipeline 301, similar to a kind of spiral blade structure, so that when the materials pass through the self-driven chamber 3012, under the action of the wind pressure and the flow force of the materials, they generate an impact force when passing through the self-driven pressure booster 3011, achieving rapid and thorough mixing), and under the action of the impeller 3014, rapid mixing of the spraying material is achieved. When the first internal transition pipe 304 connected to the inner wall of the first external transition pipe 303 and the second internal transition pipe 305 connected to one end of the first internal transition pipe 304 and located inside the first external transition pipe 303, after the spraying material undergoes preliminary transitional circulation, it generates a circulating impact force on several turbine fan blades 406 fixed on the circumferential side of the sliding cylinder 405, causing the sliding cylinder 405 to rotate on the circumferential side of the connecting column 402, thereby driving the two stirring propellers 407 fixed on the inner wall of the sliding cylinder 405 to rotate simultaneously, and then preliminarily mixing the spraying material passing through the second internal transition pipe 305, enabling the spraying material to be preliminarily mixed, and thus improving the later spraying effect;

[0045] When the sliding cylinder 405 rotates on the circumferential side of the connecting column 402, the circulating force will simultaneously generate an impact force on the sliding cylinder 405, thereby driving the sliding cylinder 405 to slide on the circumferential side of the connecting column 402, and in combination with the elastic force of the first spring 403 fixedly connected between the connecting plate 401 and the first sliding ring 404 and the second spring 410 fixedly connected between the limit nut 409 and the second sliding ring 411, driving the sliding cylinder 405 to slide reciprocally on the circumferential side of the connecting column 402, so as to stir and mix the spraying material through the two stirring propellers 407 fixed on the inner wall of the sliding cylinder 405, and thus improve the later spraying effect.

[0046] For the second embodiment, please refer to Figures 1-11, in the second embodiment, the following improvements are made on the basis of the first embodiment. Specifically, two symmetric plugging holes 412 are formed on one side of the connecting plate 401; two symmetric extension plates 307 are fixed on the inner wall of the first connecting flange 306, a rectangular frame 308 is fixed between the two extension plates 307, two symmetric threaded columns 309 are fixed on one side of the rectangular frame 308, and the two threaded columns 309 are respectively in plugging fit with the two plugging holes 412; a high-proportion connector 310 is communicated with the opposite end face of the self-driven mixing pipeline 301, and two equal-proportion connectors 311 are communicated with the opposite end faces of the two equal-proportion mixing pipelines 302; a sealing rail 312 is fixed on one side of the first connecting flange 306; the mixing assembly 2 includes a second connecting flange 201 fixedly connected with the first connecting flange 306, an annular groove 202 which is in clamping fit with the sealing rail 312 is formed on one side of the second connecting flange 201; a spiral blade mixing pipeline housing 203 is communicated on one side of the second connecting flange 201, a second external transition pipeline 204 is communicated at one end of the spiral blade mixing pipeline housing 203, a third internal transition pipeline 205 is fixed on the inner wall of the second external transition pipeline 204, a fourth internal transition pipeline 214 is communicated with a section of the third internal transition pipeline 205 located inside the second external transition pipeline 204, and an orifice plate mixing pipeline housing 206 which is communicated with the fourth internal transition pipeline 214 is communicated at one end of the second external transition pipeline 204; a plurality of spiral blades 207 are fixedly arranged in a linear array inside the spiral blade mixing pipeline housing 203, a plurality of reverse spiral blades 208 are fixedly arranged in a linear array inside the spiral blade mixing pipeline housing 203, and edge flow holes 209 are formed through one side of the spiral blades 207 and the reverse spiral blades 208; a first limiting mixing orifice plate 210 is fixed on the inner wall of the orifice plate mixing pipeline housing 206, a second limiting mixing orifice plate 211 is fixed on one side of the inner wall of the orifice plate mixing pipeline housing 206 far away from the first limiting mixing orifice plate 210, a plurality of orifice plate connecting rods 212 are fixed between the first limiting mixing orifice plate 210 and the second limiting mixing orifice plate 211, a plurality of mixing orifice plates 213 are arranged at equal intervals between the first limiting mixing orifice plate 210 and the second limiting mixing orifice plate 211, and the plurality of mixing orifice plates 213 are fixedly connected with the plurality of orifice plate connecting rods 212.

[0047] The specific application of the second embodiment is as follows: Before the use of this mixing pipeline (before use, one end of the orifice plate mixing pipeline housing 206 is sequentially connected and fixed to a conveying pipeline, a compressor, a spraying machine, and a spray gun. Among them, the conveying pipeline, the compressor, the spraying machine, and the spray gun are all prior arts and are not shown in the figure and will not be elaborated here), through the connection and fixation between the self-driven mixing pipeline 301 and an external pipeline via a high-proportion connector 310 connected to the opposite end face and between the two equal-proportion mixing pipelines 302 and an external pipeline via equal-proportion connectors 311 respectively connected to one end face, and then according to the different components, the functions of different interfaces are selected. The diameter of the self-driven mixing pipeline 301 is larger and can be connected to the higher-proportion component in components with different proportions. The equal-proportion mixing pipeline 302 can be used under the condition of 1:1 mixing, so as to achieve the spraying effect of different proportion components;

[0048] When the entire mixing pipeline sprays the two-component high molecular foam material, after the spraying material is preliminarily mixed, it enters the inside of the spiral blade mixing pipeline housing 203, so that the spiral blade mixing pipeline housing 203 plays a role in protecting the internal structure to a certain extent and becoming a circulation channel. When the preliminarily mixed spraying material passes through the spiral blades 207 and the reverse spiral blades 208 arranged inside the spiral blade mixing pipeline housing 203, the spraying material is further mixed, so that the spraying material can be shunted, cross-mixed, and reversely swirling during the flow, and combined with the edge circulation holes 209 sequentially arranged on one side of the spiral blades 207 and the reverse spiral blades 208, so that the spraying material entering the inside of the spiral blade mixing pipeline housing 203 can also flow smoothly. The entire spiral blade mixing pipeline housing 203 is slightly larger than other pipelines, further improving the mixing effect of the spraying material inside the spiral blade mixing pipeline housing 203;

[0049] After the above further mixing process ends, the spraying material flowing inside the housing 203 of the spiral vane mixing pipe enters the housing 206 of the orifice plate mixing pipe through the transition of the third internal transition pipe 205 and the fourth internal transition pipe 214 for final mixing. After the spraying material enters the housing 206 of the orifice plate mixing pipe, the housing 206 of the orifice plate mixing pipe can protect the internal structure and allow the spraying material to flow through. The first limiting mixing orifice plate 210, the mixing orifice plate 213, and the second limiting mixing orifice plate 211, as the main structures of the housing 206 of the orifice plate mixing pipe, play a role in making the liquid mix more evenly. Moreover, the first limiting mixing orifice plate 210 and the second limiting mixing orifice plate 211 are sequentially connected to the inner wall of the housing 206 of the orifice plate mixing pipe respectively, playing a certain fixing role. A number of orifice connecting rods 212 are sequentially and fixedly connected to the first limiting mixing orifice plate 210, the mixing orifice plate 213, and the second limiting mixing orifice plate 211 respectively, making the first limiting mixing orifice plate 210, the mixing orifice plate 213, and the second limiting mixing orifice plate 211 into a whole.
