TECHNICAL FIELD
[0001] The present application relates to the technical field of material mixing equipment, in particular to a mixing machine for prestressed concrete pipe pile production and a use method thereof. BACKGROUND
[0002] The prestressed concrete pipe pile has the advantages of strong bearing capacity and high construction efficiency due to the synergistic effect of centrifugal forming and prestressing process, and has been widely used in high-rise residential buildings, municipal engineering, bridge foundation and other fields. The core function is to stably transmit the upper building load to the deep foundation to ensure the overall stability of the engineering structure.
[0003] The crushed stone aggregate, as one of the core raw materials of the concrete pipe pile, bears the skeleton support role in the concrete system, and its particle size distribution and surface performance directly determine the compressive strength and structural durability of the pipe pile. However, in the raw material procurement in coastal areas, a large amount of soil impurities often adhere to the surface of the crushed stone aggregate, and these impurities are mainly clay minerals. Even after the conventional water washing treatment before the production of the pipe pile, thin film residues are still easily formed on the surface of the crushed stone, which seriously weakens the interfacial bonding strength between the cement paste and the crushed stone aggregate, and finally leads to a significant decrease in the compressive performance of the formed pipe pile, which is difficult to meet the design strength standard of building foundation engineering.
[0004] In addition to the influence of soil impurities, the crushed stone aggregate in coastal areas also faces the special problem of seawater salt adhesion. Since the stone quarry in coastal areas is often located near the sea, the crushed stone is easily in contact with seawater or salt-containing humid air during mining, transportation and stacking, resulting in a large amount of chloride ions adsorbed on the surface. These chloride ions are difficult to completely remove even after washing, and some will penetrate into the internal pores of the crushed stone. During the forming and service of the prestressed concrete pipe pile, the residual chloride ions will gradually migrate to the inside of the pipe pile and react with the prestressed steel bar through electrochemical corrosion, damaging the mechanical properties of the steel bar, and then causing the loss of prestress of the pipe pile. This double hidden danger not only reduces the bearing capacity and service life of the pipe pile, but also may cause safety risks such as building foundation settlement and cracking. Therefore, the present application provides a mixing machine for prestressed concrete pipe pile production and a use method thereof to solve the above technical problems. SUMMARY

[0025] Working principle: in the processing and production of concrete pipe pile, the cement, gravel aggregate and other materials needed for the concrete pipe pile pouring are mixed, first, the separating treatment mechanism is started, the workers connect the discharge position of the gravel material conveying equipment with the top of the feeding box through the connecting part, after the connection of the two, the gravel aggregate conveyed by the gravel material conveying equipment enters the feeding box, then the gravel aggregate in the feeding box collides with each other in the falling process, the dirt and other impurities attached to the surface of the gravel aggregate are separated, at the same time, the gravel aggregate collides with the impact plate on the rotating rod in the falling process, which also makes the dirt and other impurities attached to the surface of the gravel aggregate separate again, and when the gravel aggregate collides with the impact plate, the rotating rod and other impact plates on it are also driven to rotate synchronously, so as to continuously process the materials entering the feeding box, at the same time, the dust generated by the collision and impact in the feeding box is adsorbed and collected by the dust collector, then the gravel aggregate treated in the feeding box falls on the liquid permeation conveying belt in the treatment box, then the gravel aggregate on the liquid permeation conveying belt is conveyed to the position of high pressure spray by the liquid permeation conveying belt, at this time, the liquid pump two on the treatment box is started, the liquid pump two transports the water in the collection and circulation part of the special-shaped collection box to the distribution box on the treatment box through the connecting pipe, then the water in the distribution box is uniformly dispersed to the high pressure spray of each position, then the water is sprayed on the surface of the gravel material on the liquid permeation conveying belt after being pressurized by the high pressure spray, so as to wash the dirt and other impurities and sea salt on the surface of the gravel material again, then the washing water on the liquid permeation conveying belt after washing the gravel aggregate is discharged into the connecting collection part in the special-shaped collection box through the liquid permeation hole on the liquid permeation conveying belt, when the washing water flows in the connecting collection part, the dirt and other impurities in the water fall into the strip-shaped collection groove due to gravity, then with the continuous flow of the washing water, when it enters the collection and circulation part from the connecting collection part for recycling, the dirt and other impurities remaining in the water are filtered by the filter plate, so as to prevent the washing water in the collection and circulation part from being recycled and causing blockage and other problems, so as to complete the multiple separation treatment of the gravel aggregate.Then the precipitation wind washing mechanism starts, and the gravel aggregate treated by the separation treatment mechanism is transported to the bottom of the heating box through the liquid permeation conveying belt. At this time, the fan on the heating box starts, and the fan injects air into the inside of the heating box through the connecting pipe while the heating wire on the installation rod is electrified and generates heat. The heat generated by the heating wire heats the air in the heating box, and then the air after the heating treatment is discharged on the gravel aggregate on the liquid permeation conveying belt through the strip-shaped slot at the bottom of the heating box and the guide reflection plate on the upper part of the guide. After that, the high-temperature air discharged on the gravel aggregate dries the water and sea salt on the surface of the gravel aggregate, and the reflection of the arc-shaped part at the lower part of the guide reflection plate improves the drying effect of the gravel aggregate, so that the water on the surface of the gravel aggregate is dried and evaporated, and at the same time, the sea salt on the surface of the gravel aggregate is also precipitated and crystallized. Then the gravel aggregate after drying and evaporation crystallization is transported to the device vibration guide through the liquid permeation conveying belt, and then the vibration generated by the vibration guide guides the transportation, and at the same time, the soil impurities and salt crystallization generated by the surface drying and evaporation are separated. Then the soil impurities and salt crystallization separated by the dust collector two are collected and processed, so as to complete the wind washing and final separation treatment of the soil impurities and precipitated salt crystallization on the surface of the gravel aggregate; then the suspension mixing mechanism starts, first of all, the vacuum pump on the mixing box starts, and the vacuum pump is connected with the inside of the mixing box through the connecting pipe to form a vacuum negative pressure state. Then the liquid pump one starts, and the liquid pump one connects the mother liquor in the mother liquor tank with the inside of the atomizing ring seat through the connecting pipe to spray the mother liquor in the atomizing ring seat. At the same time, the light material in the light material box is sucked into the dispersion ring seat through the powder suction device, and then the light material in the dispersion ring seat is dispersed and discharged into the mixing box under the influence of the vacuum negative pressure state in the mixing box. Through the rotation of the mixing seat in the mixing box, a gas flow suspension mixing state is formed in the mixing box, and the atomized mother liquor and light material are continuously injected, so that the material in the mixing box is in a suspension flow state. The atomized mother liquor and light material are premixed and mixed, so as to complete the suspension mixing treatment of the mother liquor and light material.After the material mixing mechanism is started, firstly, the electromagnetic closed seat in the processing box is opened, so that the gravel aggregate treated by the separation treatment mechanism and the precipitation wind washing mechanism enters into the mixing box, and the cement conveying device inputs the quantitative cement and mixing liquid into the mixing box through the cement conveying channel, then the driving motor on the mixing box is started, the rotating shaft on the driving motor rotates and drives the driving shaft in the mixing box to rotate synchronously, the driving shaft drives the mixing seat on it to rotate synchronously, the mixing seat rotates and stirs and mixes all the materials, and the bubbles generated in the mixing process of the materials are discharged through the vacuum negative pressure environment in the mixing box, finally, the concrete material treated by mixing is discharged by the guide conveyor and injected into the pouring mold for processing of the concrete pipe pile, so that the mixing treatment of the material before the concrete pipe pile processing is completed.

[0028] 2、The application adds and sets a precipitation wind washing mechanism, when the gravel aggregate is treated, the mechanism can not only dry the residual moisture on the surface of the gravel by means of high-temperature hot air, and synchronously promote the crystallization and precipitation of residual salt in the pores, so as to cut off the path of subsequent migration and corrosion of the prestressed steel bar by chloride ions, but also can separate the crystalline salt and stubborn soil on the surface of the gravel by the vibration of the vibration guide, and then collect the crystalline salt and stubborn soil by the dust collector, so as to further improve the cleanliness of the aggregate, and the guide reflection plate can optimize the action range of the hot air, so as to ensure uniform drying and avoid the entry of the aggregate with water into the mixing link, so as to provide guarantee for the stability of subsequent material mixing.

DETAILED DESCRIPTION
[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the specification of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.
[0041] Please refer to the drawings attached Figure 1 -attached Figure 2 The embodiment of the present application provides a mixer for prestressed concrete pipe pile production, which comprises a processing box 1, a mixing box 13 is arranged on one side of the bottom of the processing box 1, an electromagnetic closed seat 24 is arranged on one side of the inner bottom end of the processing box 1, and the electromagnetic closed seat 24 controls the flow state and communication state of the materials in the processing box 1 and the mixing box 13.
[0042] Please refer to the drawings attached Figure 3 -attached Figure 5 A separation and treatment mechanism is arranged on one side of the top of the processing box 1 and used for separating and treating the soil impurities attached to the surface of the crushed stone materials before use.
[0043] The separation and treatment mechanism comprises a feed box 2, the feed box 2 is arranged in the middle of one side of the top end of the processing box 1 and is in communication with the inside of the processing box 1, a connecting part 3 is arranged on the top of the feed box 2, a rotating rod 29 is rotatably connected to the middle of the inner side of the feed box 2, a plurality of impact plates 28 are circumferentially arranged on the outer wall of the rotating rod 29, and a dust collector one 4 for sucking and collecting the separated soil dust of the crushed stone materials from the impact plates 28 is arranged on one side of the middle of the outer wall of the feed box 2.
[0044] When the separation treatment mechanism is started, the worker connects the discharge position of the gravel material conveying device to the top of the feeding box 2 through the connecting part 3. After the two are connected, the gravel aggregate conveyed by the gravel material conveying device enters the feeding box 2, and then the gravel aggregate entering the feeding box 2 collides with each other during falling, thereby separating the dirt and other impurities attached to the surface of the gravel aggregate. At the same time, the gravel aggregate collides with the impact plate 28 on the rotating rod 29 during falling, thereby synchronously separating the dirt and other impurities attached to the surface of the gravel aggregate again. When the gravel aggregate collides with the impact plate 28, the rotating rod 29 and the impact plates 28 at other positions thereon are simultaneously rotated, thereby continuously treating the material subsequently entering the feeding box 2. At the same time, the dust generated by the collision and impact in the feeding box 2 is adsorbed and collected by the dust collector 4.
[0045] The separation treatment mechanism further comprises a liquid-permeable conveying belt 19. The liquid-permeable conveying belt 19 is arranged on the inner side of the treatment box 1 close to the bottom of the feeding box 2. The inside of the liquid-permeable conveying belt 19 is provided with a special-shaped collection box 23. The special-shaped collection box 23 is composed of a connecting collection part 33 and a collection circulation part 32. The connecting collection part 33 is in the liquid-permeable conveying belt 19, and the collection circulation part 32 is outside the treatment box 1. A plurality of strip-shaped collection grooves 30 are equidistantly arranged on the inner bottom of the connecting collection part 33. A filter plate 31 is arranged at the connection between the connecting collection part 33 and the collection circulation part 32.
[0046] Then, the gravel aggregate treated in the feeding box 2 falls onto the liquid-permeable conveying belt 19 in the treatment box 1. The gravel aggregate falling onto the liquid-permeable conveying belt 19 is conveyed by the liquid-permeable conveying belt 19 to the position of the high-pressure spray 27. At this time, the liquid pump two 20 on the treatment box 1 is started. The liquid pump two 20 conveys the water in the collection circulation part 32 of the special-shaped collection box 23 to the distribution box 5 on the treatment box 1 through the connecting pipe. The water entering the distribution box 5 is uniformly dispersed into the high-pressure sprays 27 at various positions. Then, the water is pressurized by the high-pressure sprays 27 and sprayed onto the surface of the gravel material on the liquid-permeable conveying belt 19, thereby again high-pressure washing the dirt and other impurities and sea salt on the surface of the gravel material.
[0047] The separation treatment mechanism further comprises a distribution box 5. The distribution box 5 is arranged on one side of the top middle part of the treatment box 1. A plurality of high-pressure sprays 27 are equidistantly arranged on one side of the top inner wall of the treatment box 1. The liquid inlets of the high-pressure sprays 27 are in communication with the inside of the distribution box 5. A liquid pump two 20 is arranged on one side of the middle part of the rear end of the treatment box 1. The liquid pump two 20 conveys the circulating water in the collection circulation part 32 to the distribution box 5 through the connecting pipe.
[0048] After high-pressure washing of the crushed stone aggregate on the permeate conveyor belt 19, the washing water carrying the washed-out mud and impurities is discharged through the permeate holes on the permeate conveyor belt 19 into the connecting collection section 33 inside the irregular collection box 23. When the washing water flows in the connecting collection section 33, the mud and impurities in the water fall into the strip collection trough 30 due to gravity. Then, as the washing water continues to flow, when it enters the collection circulation section 32 from the connecting collection section 33 for recycling, the remaining mud and impurities in the water are filtered by the filter plate 31, thereby preventing blockage and other problems caused by the recycling of the washing water in the collection circulation section 32. This completes the multiple separation treatment of the crushed stone aggregate.

Simultaneously, the heating wire 35 on the mounting rod 34 is energized and generates heat, which heats the air entering the heating box 7.
[0052] Then, the heated air is discharged onto the crushed stone aggregate on the seepage conveyor belt 19 through the strip groove 36 at the bottom of the heating box 7 and the guide reflector plate 26. The high-temperature air discharged onto the crushed stone aggregate dries the residual moisture and sea salt on its surface. The drying effect on the crushed stone aggregate is improved by the reflection of the arc-shaped part at the bottom of the guide reflector plate 26, so that the moisture on the surface of the crushed stone aggregate is dried and evaporated.

[0065] A use method of a mixer for prestressed concrete pipe pile production, comprising the following use steps:
[0066] Step one, the staff separates the soil impurities on the surface of the gravel aggregate used in the production of prestressed concrete pipe piles by the separation treatment mechanism, so as to improve the surface cleanliness of the gravel aggregate during use;
[0067] Step two, then the gravel aggregate treated by the separation treatment mechanism is high-temperature dried by the precipitation washing mechanism, so as to separate the residual soil impurities on the surface of the gravel aggregate, and at the same time, the residual salt crystals on the surface of the gravel aggregate are also separated, and then the residual soil mixture and sea salt crystals are separated from the gravel aggregate;
[0068] The above operation method steps process the gravel aggregate in steps, first remove the surface soil impurities by the separation treatment mechanism to effectively improve the cleanliness of the aggregate, avoid the formation of "isolation layer" in the subsequent mixing, create conditions for the full bonding of cement paste and aggregate, and reduce the problem of pipe pile compressive strength reduction caused by insufficient interface bonding. Then through the high-temperature drying and separation operation of the precipitation washing mechanism, not only the residual soil is stripped, but also the salt crystals are separated and separated, which blocks the path of chloride ion migration into the pipe pile from the source, avoids the corrosion of prestressed steel bar, double guarantees the structural strength and durability of the pipe pile, and reduces the probability of safety risks such as settlement and cracking during service.

[0072] Subsequently, the remaining materials are injected and terminal mixing is completed through the material mixing mechanism, which can integrate and stir the pretreated aggregate, pre-mixed material and other components to ensure the overall uniformity of the concrete, adapt to the requirements of dry concrete for pipe pile centrifugal forming, reduce the uneven density defects of the pile body after forming, and at the same time, the steps are smoothly connected, improving the continuity and efficiency of the mixing process and ensuring the stable quality of the finished pipe pile.
