Abstract
Description
Technical Field
[0001] The invention relates to the technical field of high-performance concrete production, and in particular to a production process and equipment for preparing high-performance concrete from slag. Background Art
[0002] Concrete is one of the most important civil engineering materials in contemporary times and an important building material. It is widely used in construction, roads, bridges and other fields. Concrete in the traditional sense refers to an artificial stone made by mixing cementitious materials, coarse aggregate, fine aggregate, water, and admixtures and additives added in a certain proportion when necessary, and then evenly stirring, compacting, and curing and hardening.
[0003] In the process of preparing concrete, the raw materials required, such as cement, aggregate and water, are placed in a mixing device in a certain mixing ratio, and these raw materials are fully mixed together through stirring for a certain period of time. The current concrete mix design method is to calculate by the volume weight percentage method on the premise that the mixture meets the construction fluidity and workability and the mixture meets the strength and durability after solidification and reaching a certain age.
[0004] When this method is actually used, concrete is prepared by tossing and dispersing the gel slurry and aggregates during mixing, and then evenly distributing and reorganizing them under the action of gravity. The cementitious material reacts with water to form a gel to fill the gaps between the aggregates. However, the aggregates often hinder the cementitious slurry from evenly and fully filling the gaps. In this state, only stirring cannot fully fill the gaps between the aggregates with these gel colloids, which will cause a certain reduction in the performance of the final concrete produced, resulting in the concrete being unable to meet the use requirements. Summary of the invention

A first spring is arranged inside the fixed cylinder, and a lifting groove is opened on the lifting ring plate, and the lifting groove is engaged and slidably engaged with the engaging rod.
[0011] As a preferred solution of the production equipment for preparing high-performance concrete from slag described in the present invention, the air extraction component includes a vacuum pump arranged on a protective shell, an air duct arranged on the vacuum pump, an air intake bin arranged at an end of the air duct away from the vacuum pump, an L-shaped slide plate symmetrically arranged inside the air intake bin, and a partition plate arranged inside the air intake bin.
[0012] As a preferred solution of the production equipment for preparing high-performance concrete from slag described in the present invention, wherein: rotating cylinders are arranged in an array on the partition plate, threaded sleeves are arranged in an array on the L-shaped slide plate, and the threaded sleeves are threadedly connected to the rotating cylinders, fixed square rods are arranged in an array on the partition plate, matching sleeves are arranged on the fixed square rods, and the matching sleeves are threadedly connected to the rotating cylinders, a second spring is arranged on the outside of the rotating cylinder, and air intake holes are arranged in an array on the air intake bin.
[0013] As a preferred solution of the production equipment for preparing high-performance concrete from slag described in the present invention, a ventilation pipe is arranged inside the air guide pipe, and the ventilation pipe runs through the air guide pipe, and a telescopic fixing plate is arranged at one end of the air guide pipe away from the air guide pipe.
[0014] The present invention also provides the following technical solutions: a production process and equipment for preparing high-performance concrete from slag, including the following production process: first, the raw materials are put into the preparation tank through the feed port, and the driving component is started to drive the eccentric plate to drive the stirring roller to perform eccentric stirring, thereby increasing the entire stirring range, and the locking rod on the sleeve ring is driven to slide along the lifting groove on the lifting ring plate under the rotation of the stirring roller, so that the lifting ring plate drives the fixed screen plate to move after being squeezed by the locking rod, and the fixed screen plate is reset by the first spring after moving to a certain position to achieve oscillation;
[0015] Secondly, during the entire eccentric stirring and oscillating stirring process, the air inside the raw material will be expelled through the squeezing of the fixed sieve plate, and then the vacuum pump provided on the preparation tank will be started to perform a vacuum operation on the inside of the preparation tank, so that the air inside the preparation tank will be extracted, and the air inside the raw material will also be extracted. When a negative pressure state appears inside the preparation tank, when the pressure inside the telescopic fixed plate is consistent with the external pressure through the vent pipe, the L-shaped slide plate will be pushed to close the air inlet hole on the air inlet bin, so that the inside of the preparation tank maintains a negative pressure state, so that it can cooperate with eccentric stirring and oscillating stirring to process the raw materials;
[0016] Finally, after the entire mixing is completed, the rotation of the stirring roller is stopped by turning off the motor, and the fixed screen plate is also stopped from working so as not to oscillate the raw materials inside the preparation tank, and then the raw materials inside the preparation tank are discharged.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. When the matching roller arranged on the preparation tank rotates, the stirring roller can make an eccentric rotation around the matching roller, and the raw materials put into the preparation tank are fully stirred under the action of the stirring blades on the stirring roller. During the whole stirring process, the eccentric rotation of the stirring roller will increase the stirring range of the whole stirring roller. At the same time, the eccentric rotation of the stirring roller can also drive the fixed screen plate to perform reciprocating lifting and shaking, so that the dispersion and mixing between the raw materials can be more uniform;
[0019] 2. At the same time, the reciprocating lifting speed of the fixed sieve plate is not consistent, so when the fixed sieve plate is reset under the action of the lifting groove set on the lifting ring plate, the mixed raw materials can be vibrated through the fixed sieve plate. During the shaking process, the mixed raw materials will be transferred through the through holes on the fixed sieve plate, so that some agglomerated raw materials will be dispersed under this shaking and extrusion. The dispersed raw materials will be pushed by the stirring blades and remixed with other raw materials, so that the whole raw materials are mixed more fully. At the same time, the shaking of the raw materials by the fixed sieve plate can shake out the residual air inside the raw materials;
[0020] 3. At the same time, when the raw materials are mixed, start the vacuum pump to extract the air inside the preparation tank. As a negative pressure state is gradually formed inside the preparation tank, the air remaining in the mixed raw materials will be sucked out to make the entire raw material mixture more compact. At the same time, the telescopic fixed plate set in this process will gradually extend to push the L-shaped slide plate to slide inside the air intake bin, so that the L-shaped slide plate will eventually block the air intake hole on the air intake bin, forming a sealed negative pressure cavity inside the entire preparation tank, so that the entire raw material is in a negative pressure state during mixing, avoiding residual air from affecting the entire concrete preparation.

DETAILED DESCRIPTION
[0032] The features and exemplary embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the need for some of these specific details.

In the accompanying drawings and the following description, known structures and technologies are not shown to avoid unnecessary ambiguity to the present invention.
[0033] Example 1
[0034] Reference Figure 1-7 , which is the first embodiment of the present invention, provides a production equipment for preparing high-performance concrete from slag, and the production equipment for preparing high-performance concrete from slag includes a frame 1, the frame 1 is used to support and fix the preparation tank 2 as a whole, so as to prevent the vibration of the preparation tank 2 during the preparation of high-performance concrete from affecting the stability of the entire preparation tank 2, the frame 1 is provided with the preparation tank 2, the preparation tank 2 is provided with a driving component 3, the driving component 3 is used to provide power to drive the stirring inside the preparation tank 2, the preparation tank 2 is provided with a feed port 21, the feed port 21 is used to put various raw materials, so as to facilitate the preparation of high-performance concrete, the preparation tank 2 is provided with a stirring component 4, the stirring component 4 is used to stir the raw materials inside the preparation tank 2 to make them more fully mixed;
[0035] The driving assembly 3 includes a motor 31 disposed on the preparation tank 2. The motor 31 is installed on one side of the preparation tank 2. The motor 31 is started to provide power to drive the rotating shaft 32 to rotate. The power is transmitted to the matching roller 34 through the transmission belt 33 on the rotating shaft 32, so that the matching roller 34 rotates, and the eccentric plate 35 at one end of the matching roller 34 is driven to rotate. The rotating shaft 32 is arranged at one end of the motor 31, and the transmission belt 33 is arranged on the rotating shaft 32. The transmission belt 33 is used to transmit the rotation of the rotating shaft 32 to the matching roller 34.
[0036] A matching roller 34 is arranged on the side of the transmission belt 33 away from the rotating shaft 32, and the matching roller 34 is engaged and rotated with the preparation tank 2. The matching roller 34 is used to drive the eccentric plate 35 at the other end of the matching roller 34 to oscillate around the matching roller 34 while rotating. Under the rotation of the eccentric plate 35, the stirring roller 41 engaged and rotating thereon is synchronously driven, so that the stirring roller 41 oscillates inside the preparation tank 2, thereby increasing the coverage range of the stirring roller 41. The eccentric plate 35 is arranged at one end of the matching roller 34.
[0037] The preparation tank 2 is provided with a protective shell 22, which is used to protect the rotating shaft 32 and the transmission belt 33 on the motor 31 to prevent the surrounding staff from accidentally touching the transmission belt 33 and causing injuries during the startup of the entire device. The mating roller 34 is provided with a fixed gear 341 at one end close to the eccentric plate 35, and the fixed gear 341 is used to mesh with the rotating gear 42. Under the action of meshing, the stirring roller 41 fixed to the rotating gear 42 is rotated, so that when the stirring roller 41 eccentrically swings to increase the entire stirring range, the stirring roller 41 itself can also rotate synchronously, so that the overall stirring efficiency can be improved;
[0038] The protective shell 22 is provided with an exhaust assembly 5, which is used to exhaust the air inside the preparation tank 2 to form a negative pressure state inside the preparation tank 2. When the raw materials inside the preparation tank 2 are stirred and mixed, the raw materials under the negative pressure state cause the air filled inside to be discharged during the stirring process, so that the mixing is more complete and the performance of the concrete is improved.
[0039] The stirring assembly 4 includes a stirring roller 41 movably arranged on the eccentric plate 35. The stirring roller 41 and the eccentric plate 35 are in a locking rotation relationship. A rotating gear 42 is arranged on the stirring roller 41. Through the meshing relationship between the rotating gear 42 and the fixed gear 341, when the fixed gear 341 is driven by the matching roller 34 to rotate, the rotation can be transmitted to the stirring roller 41 through the meshing rotating gear 42, so that when the stirring roller 41 rotates eccentrically around the matching roller 34, the stirring roller 41 itself can also rotate. Under the action of the two, the stirring roller 41 can increase the stirring range while stirring, and can also improve the overall stirring efficiency through its own rotation;
[0040] A rotating gear 42 is arranged on the stirring roller 41, and the rotating gear 42 is meshed with the fixed gear 341. The meshing between the rotating gear 42 and the fixed gear 341 can make full use of the power transmitted by the matching roller 34, so that the raw materials put into the preparation tank 2 are fully mixed under the entire meshing action to avoid agglomeration. The stirring blades 43 are arranged in an array on the stirring roller 41. The stirring blades 43 are used to rotate synchronously under the drive of the stirring roller 41. The stirring blades 43 have a certain degree of twisting and inclination. When the stirring blades 43 push the raw materials inside the preparation tank 2 to mix, the twisted stirring blades 43 provide thrust to push the raw materials inside the preparation tank 2 to move, and a part of the mixed raw materials can be re-broken up by the stirring blades 43 for re-mixing.
[0041] The agitator roller 41 is provided with a sleeve ring 411 in an array, and the sleeve ring 411 and the agitator roller 41 are engaged and rotated. The sleeve ring 411 forms an engagement and sliding relationship with the lifting groove 651 on the lifting ring plate 65 through the locking rod 412 provided thereon. When the agitator roller 41 rotates eccentrically, the locking rod 412 on the sleeve ring 411 will slide inside the lifting groove 651, thereby squeezing the entire lifting ring plate 65 to perform reciprocating lifting and lowering. Under the lifting and lowering of the lifting ring plate 65, the fixed sieve plate 64 is driven to reciprocate up and down in the preparation tank 2, and the vibration stirring of the fixed sieve plate 64 is formed under the vibration of the fixed sieve plate 64. In this process, the agitator roller 41 itself cooperates with its own swing and stirring action to fully disperse the raw materials, so as to avoid the raw materials being unable to be mixed alternately up and down during stirring, resulting in poor final mixing efficiency, so that the working performance of the concrete cannot be effectively improved.
[0042] A locking rod 412 is provided on the sleeve ring 411, and the locking rod 412 is used to form a locking and sliding relationship with the lifting groove 651 provided on the lifting ring plate 65. An oscillation component 6 is provided inside the preparation tank 2, and the oscillation component 6 is used to cooperate with the stirring roller 41 to oscillate the raw materials inside the preparation tank 2 to make the mixing of the raw materials more dispersed.
[0043] During use, first, all the raw materials for preparing concrete are put into the preparation tank 2 through the feed port 21, and then the motor 31 is started to transmit power to the matching roller 34 through the transmission belt 33 under the action of the rotating shaft 32. Under the rotation of the matching roller 34, the eccentric plate 35 arranged at one end of the matching roller 34 is eccentrically rotated, thereby driving the stirring component 4 to stir the raw materials inside the preparation tank 2. During the entire stirring process, the interior of the preparation tank 2 is evacuated by starting the exhaust component 5, so that a negative pressure state is formed inside the entire preparation tank 2. In this state, part of the air mixed in the raw materials can be sucked out, so that the raw materials inside are mixed more densely. In this process, a negative pressure sealed environment is formed inside the preparation tank 2. After the stirring of the raw materials is completed, the vacuum pump 51 is started to transport air to the preparation tank 2, so that the pressure inside the preparation tank 2 gradually returns to balance, so that it is convenient to finally take the stirred concrete out of the entire preparation tank 2.
[0044] Example 2
[0045] Reference Figure 1-7 , which is the second embodiment of the present invention, and this embodiment is different from the first embodiment in that:
[0046] The oscillation assembly 6 includes a support plate 61 arranged in an array inside the preparation tank 2, the support plate 61 is used to support the fixed cylinder 62, the fixed cylinder 62 is arranged in an array on the support plate 61, the fixed cylinder 62 has a cavity inside, the first spring 621 and the sliding rod 63 arranged in the cavity of the fixed cylinder 62 will reset the fixed sieve plate 64, so that the fixed sieve plate 64 can perform reciprocating lifting and shaking, and the sliding rod 63 is movably arranged inside the fixed cylinder 62, and a section of the sliding rod 63 is in the cavity inside the fixed cylinder 62, so that when the sliding rod 63 follows the fixed sieve plate 64 to extend to the extreme position, a part of the sliding rod 63 is still inside the fixed cylinder 62, so that the sliding rod 63 and the fixed cylinder 62 will not be separated;
[0047] A fixed sieve plate 64 is arranged at one end of the sliding rod 63 away from the fixed cylinder 62. The fixed sieve plate 64 has many through holes. These through holes are used to disperse the raw materials in the preparation tank 2 when the fixed sieve plate 64 is raised or lowered, so that the dispersed raw materials can be mixed again under the stirring of the stirring blade 43. A lifting ring plate 65 is arranged at the center of the fixed sieve plate 64 to fix it.
[0048] The lifting ring plate 65 is arranged on the fixed sieve plate 64, and is located at the center of the fixed sieve plate 64. At the same time, a lifting groove 651 is opened on the inner wall of the lifting ring plate 65. The lifting ring plate 65 is lifted and lowered reciprocatingly through the cooperation between the lifting groove 651 and the engaging rod 412. During the lifting and lowering process of the lifting ring plate 65, the lifting ring plate 65 is reset instantly through the straight groove of the lifting groove 651, thereby realizing the instantaneous vibration of the fixed sieve plate 64 on the raw material.
[0049] A first spring 621 is provided inside the fixed cylinder 62. The first spring 621 is used to provide elastic force. When the sliding rod 63 is driven by the fixed screen plate 64 to retract into the fixed cylinder 62, the first spring 621 is squeezed. After the first spring 621 is squeezed, when the clamping rod 412 moves to the straight slot of the lifting groove 651, the clamping rod 412 will instantly break away from the squeezing effect on the lifting ring plate 65, so that the lifting ring plate 65 will be immediately reset under the action of the first spring 621, thereby resetting the fixed screen plate 64 and performing a continuous up and down reciprocating vibration state.
[0050] A lifting groove 651 is provided on the lifting ring plate 65, and the lifting groove 651 is engaged and slid with the engaging rod 412. The lifting groove 651 is a ring groove connected to a straight groove. When the engaging rod 412 squeezes and slides the lifting ring plate 65, when the engaging rod 412 moves to the straight groove, the lifting ring plate 65 and the fixed sieve plate 64 are instantly reset under the action of the first spring 621. At the same time, during the resetting process, the fixed sieve plate 64 will break up the raw materials inside the preparation tank 2, so that the raw materials inside are mixed more evenly.
[0051] During use, when the eccentric plate 35 rotates eccentrically around the matching roller 34, the fixed gear 341 provided on the matching roller 34 will drive the entire stirring roller 41 to rotate itself through the rotating gear 42 meshing with the stirring roller 41, so that the stirring roller 41 can also rotate itself while being driven by the eccentric plate 35 to rotate eccentrically, so that the stirring roller 41 can not only increase the stirring range under the action of the two, but also improve the overall stirring efficiency through its own rotation. When the stirring roller 41 rotates eccentrically, the sleeve ring 411 sleeved on the stirring roller 41 can adjust the lifting ring plate 65 through the locking rod 412 provided thereon. The lifting groove 651 is squeezed, causing the lifting ring plate 65 to drive the fixed sieve plate 64 to oscillate back and forth up and down inside the preparation tank 2. During the lifting process of the lifting ring plate 65, when the engaging rod 412 moves to the straight groove of the lifting groove 651, the engaging rod 412 will instantly break away from the squeezing effect on the lifting ring plate 65, so that the lifting ring plate 65 will immediately reset under the action of the first spring 621, thereby realizing the instantaneous reset of the fixed sieve plate 64, thereby causing instantaneous vibration to the raw material, so that while the raw material is eccentrically stirred, the set fixed sieve plate 64 can squeeze and oscillate the raw material up and down, thereby expanding the overall stirring efficiency and range.
[0052] The remaining structures are the same as those of Example 1.
[0053] Example 3
[0054] Reference Figure 1-10 , which is the third embodiment of the present invention. This embodiment is different from the first and second embodiments in that:
[0055] The exhaust assembly 5 includes a vacuum pump 51 arranged on the protective shell 22, and the vacuum pump 51 is used to exhaust the air inside the preparation tank 2, so that a negative pressure state is formed inside the preparation tank 2, so that the air filled in the raw materials can be exhausted, so that the raw materials inside are mixed more densely, and an air guide pipe 52 is arranged on the vacuum pump 51, and a section of the air guide pipe 52 runs through the preparation tank 2, and is used to exhaust the air inside the preparation tank 2 through the vacuum pump 51, and an air inlet bin 53 is arranged at an end of the air guide pipe 52 away from the vacuum pump 51. The air inlet bin 53 is arranged inside the preparation tank 2 and is connected to the air guide pipe 52 through the internal cavity. At the air inlet holes 531 arranged in an array on the air inlet bin 53, when the vacuum pump 51 is started to exhaust, the gas inside the preparation tank 2 will enter the air guide pipe 52 from the cavity of the air inlet bin 53 through the air inlet holes 531, and finally be exhausted by the vacuum pump 51, so that a negative pressure state is formed inside the preparation tank 2 The L-shaped slide plate 54 is symmetrically arranged inside the air inlet bin 53. A plurality of through holes are arranged in an array on the support plate of the L-shaped slide plate 54 perpendicular to the air inlet hole 531 to facilitate the air inside the air inlet bin 53 to be extracted. When the air inside the preparation tank 2 is continuously extracted, the pressure inside the air inlet bin 53 decreases. At the same time, the telescopic fixing plate 561 arranged inside the air inlet bin 53 is communicated with the outside through the vent pipe 56, so that when the pressure inside the telescopic fixing plate 561 is unbalanced with the internal pressure of the air inlet bin 53, the telescopic fixing plate 561 will extend to push the L-shaped slide plate 54 to move, and finally block the air inlet hole 531 set on the air inlet bin 53, thereby forming a negative pressure sealed environment inside the entire preparation tank 2, and a partition plate 55 is arranged inside the air inlet bin 53. The partition plate 55 is used to divide the air inlet bin 53 into two separate areas. At the same time, the partition plate 55 can support the rotating cylinder 551.
[0056] The partition plate 55 is provided with a rotating cylinder 551 in an array, and the rotating cylinder 551 has a cavity, and thread grooves are provided on both the inner and outer sides of the rotating cylinder 551. The rotation directions of the inner and outer thread grooves are exactly the same, so that when the L-shaped slide plate 54 moves, the rotating cylinder 551 can be driven to rotate by the threaded sleeve 541 on the L-shaped slide plate 54. A through hole is provided in an array at one end of the rotating cylinder 551, so that when the L-shaped slide plate 54 needs to be reset at the end, the vacuum pump 51 can push the matching sleeve 553 to move through the through hole when sending air to the inside of the air inlet bin 53, so that the rotating cylinder 551 rotates, so that the L-shaped slide plate 54 moves driven by the threaded sleeve 541 to complete the entire reset. A threaded sleeve 541 is threadedly connected with the rotating cylinder 551. A fixed square rod 552 is arranged in an array on the partition plate 55. A matching sleeve 553 is sleeved on the fixed square rod 552. The matching sleeve 553 is threadedly connected with the rotating cylinder 551. When the rotating cylinder 551 is driven to rotate by the L-shaped slide plate 54, the matching sleeve 553 arranged inside the rotating cylinder 551 will be driven by the fixed square rod 552 and the rotating cylinder 551 to make the matching sleeve 553 move synchronously. A second spring 554 is sleeved on the outside of the rotating cylinder 551. The second spring 554 is used to provide elastic force to provide additional power when the L-shaped slide plate 54 is reset. An air inlet hole 531 is arranged in an array on the air inlet bin 53.
[0057] A ventilation pipe 56 is arranged inside the air guide pipe 52, and the ventilation pipe 56 runs through the air guide pipe 52. The ventilation pipe 56 is used to connect the telescopic fixing plate 561 with the outside. When the pressure inside the air inlet bin 53 continues to decrease, the telescopic fixing plate 561 will push the L-shaped slide plate 54 to move under the state of pressure imbalance, thereby blocking the air inlet hole 531 on the air inlet bin 53, so that the inside of the preparation tank 2 is sealed. A telescopic fixing plate 561 is arranged at one end of the ventilation pipe 56 away from the air guide pipe 52. The telescopic fixing plate 561 is a telescopic fixing plate, and its external fixing plate has a cavity, and the internal telescopic plate does not completely fill the cavity in the external fixing plate, so that when the telescopic fixing plate 561 is under the negative pressure state inside the air inlet bin 53, the telescopic fixing plate 561 can be extended to push the L-shaped slide plate 54 to move.
[0058] During use, in the process of stirring the raw materials, a certain amount of air will be generated by the mixing of various raw materials. At the same time, in order to make the mixing of the various raw materials more dense, the air inside the preparation tank 2 is extracted by starting the vacuum pump 51, so that a negative pressure state is formed inside the preparation tank 2. In the process of extracting air, the telescopic fixed plate 561 arranged inside the air inlet bin 53 is connected to the outside through the vent pipe 56, so that the pressure inside the telescopic fixed plate 561 will not change, and the internal pressure of the air inlet bin 53 will continue to decrease. At this time, the telescopic fixed plate 561 will extend under the action of pressure, thereby pushing the L-shaped slide plate 54 to move, and finally blocking the air inlet hole 531 set on the air inlet bin 53, so that a negative pressure sealed environment is finally formed inside the entire preparation tank 2, which is convenient for the final full mixing of the concrete.
[0059] The remaining structures are the same as those of embodiments 1 and 2.
[0060] Example 4
[0061] See also Figures 1 to 10 , which is the fourth embodiment of the present invention, and provides: a production process and equipment for preparing high-performance concrete from slag, including the following production process:
[0062] S1, firstly, the raw materials are put into the preparation tank 2 through the feed port 21, and the driving assembly 3 is started to cause the eccentric plate 35 to drive the stirring roller 41 to perform eccentric stirring, thereby increasing the entire stirring range, and the locking rod 412 on the sleeve ring 411 is driven to slide along the lifting groove 651 on the lifting ring plate 65 under the rotation of the stirring roller 41, so that the lifting ring plate 65 drives the fixed screen plate 64 to move after being squeezed by the locking rod 412, and after moving to a certain position, the fixed screen plate 64 is reset by the first spring 621 to achieve oscillation;
[0063] S2, secondly, during the entire eccentric stirring and oscillating stirring process, the air inside the raw material will be expelled through the squeezing of the fixed sieve plate 64, and then the vacuum pump 51 provided on the preparation tank 2 is started to perform a vacuum operation on the inside of the preparation tank 2, so that the air inside the preparation tank 2 is extracted, and the air inside the raw material is also extracted. When a negative pressure state appears inside the preparation tank 2, when the pressure inside the telescopic fixed plate 561 is consistent with the external pressure through the vent pipe 56, the L-shaped slide plate 54 will be pushed to close the air inlet hole 531 on the air inlet bin 53, so that the inside of the preparation tank 2 maintains a negative pressure state, so that it can cooperate with the eccentric stirring and oscillating stirring to process the raw material;
[0064] S3, after the entire mixing is completed, the rotation of the stirring roller 41 is stopped by turning off the motor 31, and the fixed screen plate 64 is also stopped to no longer vibrate the raw materials inside the preparation tank 2. Then, a concrete pump is connected to the discharge port of the preparation tank 2, and then the switch valve at the discharge port of the preparation tank 2 is opened, and the prepared materials are pumped out by the concrete pump to facilitate people to discharge the materials.
