[0003] There are two major problems in the preparation of concrete in existing mixing stations or concrete production lines. One is dust. Since cement and fly ash are powder materials, dust is easily generated during the loading or unloading process, and a large amount of dust comes from these two raw materials. Although many mixing stations need to add an additional set of dust removal equipment to avoid dust, or use water spraying to suppress or remove the raised dust, the dust cannot be effectively removed to a greater or lesser extent; secondly, the wastewater used to treat the dust is usually not well recycled and utilized, and is finally discharged as waste, which is easy to pollute the environment. Based on this, the present invention improves the foundation and divides the traditional concrete production into two stages. The cement and fly ash that are prone to generate dust are pre-treated, and a dust treatment mechanism and a waste recycling mechanism are added.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention is an innovative technology in the production method and supporting equipment of concrete. The traditional production method and supporting production line are to put cement, fly ash, sand, gravel and admixtures into a mixer in a certain order and mix them evenly to obtain concrete. The present invention divides the traditional production line and method into two stages. The present invention is a front-end device. Through the present invention, cement, fly ash and admixtures can be produced in advance. Specifically, a series of functional components such as a storage bin, a weighing mechanism, a mixing mechanism, a feeding mechanism and an exhaust gas treatment are integrated into a whole. The integration is ingenious, and it has the characteristics of occupying a small space and powerful functions.

[0017] 2. By setting up a dust removal water tank, the present invention can deal with dust at the source, effectively solving the problem of dust in the concrete production process. The main sources of dust are cement and fly ash. The present invention respectively provides a cement dust removal pipe and a fly ash dust removal pipe on the top of the cement storage bin and the fly ash storage bin, and extends the end of the dust removal main pipe into the dust removal water tank. Cement or fly ash is prone to generate dust during the loading / unloading process. The present invention collects the dust generated by the two through the dust removal main pipe and discharges it into the water. The cement dust and fly ash dust are dissolved in the water, which effectively solves the problem of dust. The water dissolved by cement and fly ash can be put into the mixer through the sewage pipe and the water pump. Since the mixer is mainly used for mixing cement and fly ash, which are of the same origin, the discharge of wastewater into the mixer will not affect the quality of cement mortar. The whole process achieves dust suppression and wastewater recovery, avoiding the discharge of waste.

[0018] 3. The present invention connects the weighing sensor to the top of the base box in a detachable manner, and the top of the weighing sensor is fixedly connected to the bottom of the storage box. By setting the weighing sensor, the conditions of the materials in the cement storage bin and the fly ash storage bin can be effectively measured and monitored in real time, including accurate weighing of the materials and monitoring of the weight of the added materials.

[0032] The specific embodiments of the present invention are further described below in conjunction with the accompanying drawings. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention. In addition, the technical features involved in the various embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0033] like Figures 1 to 13 As shown, a multifunctional powder storage and slurry prefabrication device includes a base box 1 and a storage box 2, wherein the base box 1 serves as the basic base of the entire equipment and is used to place functional equipment; a dust removal water tank 11, an agitator 12 and an additive adding mechanism 13 are arranged in the base box 1; the additive adding mechanism 13 of the present invention is used to add additives to the agitator 12, and conventional equipment is selected, which is mainly composed of an additive adding box, a pump, a pipeline and a weighing device. The additive is pumped into the weighing device by a pump, and after reaching a certain amount, it is discharged into the agitator 12.

[0034] like Figure 4 , Fig.10 , Fig.11As shown, the top of the base box 1 of the present invention is connected to the weighing sensor 3 in a detachable manner, and the top of the weighing sensor 3 is fixedly connected to the bottom of the material storage box 2; the weighing sensor 3 of the present invention is welded to the fixed position by screws and nuts, and the top of the weighing sensor 3 is welded to the bottom of the material storage box 2. The weighing sensor 3 of the present invention is a column weighing sensor, which is an existing conventional device. Preferably, the number of them is six, which are respectively arranged at the top of the four corners of the base box 1 and the top in the middle of the base box 1.

[0035] The specific working principle of weighing is: due to the total weight of the entire storage box 2 and the materials stored in the box, when there is no material in the entire storage box 2, the mass of the entire empty storage box 2 is weighed, and the value recorded at this time is M 0 If a certain amount of material is put into the storage box 2, the value recorded on the weighing sensor 3 is M 1 , the input material is: M 投 =M 1 -M 0 When the material stored in the storage box 2 is M 2 After discharge, its value is displayed as M 3 , the discharged material M 排 =M 2 -M 3 In this way, the material in and out process in the storage box 2 is recorded, and the input material or the discharged material is accurately weighed.

[0036] The storage box 2 is divided into a cement storage bin 21 and a fly ash storage bin 22 by a partition 20. The partition 20 of the present invention is fixed to the crossbeam of the storage box 2 by screws and nuts, dividing the storage box 2 into two parts, which are respectively used to store cement and fly ash. Since these two materials need to be exhausted during the loading and unloading processes, and since a large amount of dust is mixed in the gas, it is necessary to remove it. Therefore, the present invention is provided with a cement dust removal pipe 211 and a fly ash dust removal pipe 221 on the top of the cement storage bin 21 and the fly ash storage bin 22, respectively. The cement dust removal pipe 211 and the fly ash dust removal pipe 221 are both connected to the dust removal main pipe 4, the end of the dust removal main pipe 4 extends into the dust removal water tank 11, and the bottom of the dust removal water tank 11 is connected to the sewage pipe 111. The sewage pipe 111 is provided with a water pump 112, and the end of the sewage pipe 111 is connected to the agitator 12. At the same time, in order to play a filtering role and prevent a large amount of dust or fly ash from entering the dust removal main pipe 4, the feed ends of the cement dust removal pipe 211 and the fly ash dust removal pipe 221 of the present invention are both provided with microporous baffles (not shown in the figure).

[0037] The principle of dust removal and waste recycling is as follows: Take cement as an example. When cement needs to be added into the cement storage bin 21, the cement feeding pipe 210 is used in conjunction with the air pump to suck the cement into the cement storage bin 21. The cement enters the cement storage bin 21 from bottom to top through the cement feeding pipe 210. Since a plurality of discharge ports are provided at the top of the cement feeding pipe 210, cement enters the cement storage bin 21 from the discharge ports. Excess gas mixed with cement ash enters the dust removal main pipe 4 from the cement dust removal pipe 211. The principle of fly ash is the same. Finally, the dust removal main pipe 4 is mixed with air and dust. The dust enters the dust removal water tank 11, and the dust gradually enters the water and is continuously absorbed. Finally, the water is mixed with a mixture of water, cement and fly ash. If discharge is required, the water pump 112 is started to pump the entire mixture in the dust removal water tank 11 into the mixer 12. In this way, the dust can be well avoided from being discharged into the air, and the waste can be well collected and utilized. Since these mixtures are of the same origin as the cement and fly ash in the mixer 12, adding them will not affect their quality. In this way, the dust problem in the concrete production process is effectively solved.

[0038] Of course, in order to better remove dust, the present invention further optimizes the structure of the dust removal water tank 11. Fig. 9 As shown, a partition plate 113 is provided in the dust removal water tank 11 of the present invention, and the partition plate 113 divides the dust removal water tank 11 into a primary dust removal filter box 114 and a secondary dust removal filter box 115. An exhaust hole 116 is provided between the primary dust removal filter box 114 and the secondary dust removal filter box 115. The width ratio of the primary dust removal filter box 114 and the secondary dust removal filter box 115 of the present invention is 1:2, and the aperture of the exhaust hole 116 is larger than the aperture of the dust removal main pipe 4. Since the exhaust port of the dust collection main pipe 4 of the whole link is about 30cm underwater, when the dust gas in the dust collection main pipe 4 enters the primary dust collection filter box 114, a large number of bubbles will be generated in the primary dust collection filter box 114, and the dust will continue to dissolve into the water. Since the entire exhaust process is continuously carried out, when the gas in the primary dust collection filter box 114 is full, it will enter the secondary dust collection filter box 115 along the exhaust hole 116. Since the aperture of the exhaust hole 116 is larger than the aperture of the dust collection main pipe 4, it is sufficient to ensure that the primary dust collection filter box 114 will not burst, and the gas in the secondary dust collection filter box 115 will not burst. The dust filter box 115 is continuously mixed with water, so the dust can be better removed. If at this time, there is still floating dust in the primary dust filter box 114, the structure of the dust removal water tank 11 can be further optimized. Specifically, a spray pipe 117 is provided on the top of the secondary dust filter box 115. The spray pipe 117 is connected to a water pump through a water inlet pipe. The water pump is placed in the secondary dust filter box 115. Water is sprayed through the spray pipe 117 to further remove the dust. The purified gas is discharged from the exhaust hole of the secondary dust filter box 115 to complete the purification process.

[0039] Since the dust dissolves into the water, the mixture in the dust removal water tank 11 needs to be drained to ensure that dust removal can continue next time. Therefore, the present invention provides a primary drain pipe 118 at the bottom of the primary dust removal filter box 114, and a secondary drain pipe 119 at the bottom of the secondary dust removal filter box 115. The primary drain pipe 118 and the secondary drain pipe 119 are connected in parallel to the drain pipe 111.

[0040] Since dust is mainly deposited in the primary dust removal filter box 114, in order to facilitate better discharge during discharge, the present invention further provides a sludge scraping mechanism 1140 in the primary dust removal filter box 114. The sludge scraping mechanism 1140 includes a pusher hydraulic cylinder 1141 and a material removal shovel 1142. The piston rod of the pusher hydraulic cylinder 1141 is connected to the end of the material removal shovel 1142. The pusher hydraulic cylinder 1141 pushes the material removal shovel 1142 forward or backward to scrape off the sludge at the bottom of the primary dust removal filter box 114. The sludge scraping mechanism 1140 is used to turn over the sludge for better discharge.

[0041] A first dragon conveying mechanism 5 for conveying cement is provided at the bottom of the cement storage bin 21, and a second dragon conveying mechanism 6 for conveying fly ash is provided at the bottom of the fly ash storage bin 22. The discharge ends of the first dragon conveying mechanism 5 and the second dragon conveying mechanism 6 are respectively connected to the agitator 12 through pipelines.

[0042] Since the control switch of the traditional dragon conveying mechanism is mostly gate valve or butterfly valve, due to its special structure, if the parts of the dragon need to be replaced during use, and materials are stored in the dragon, this operation cannot be performed. In order to solve this problem, the present invention further optimizes the dragon conveying mechanism, such as Figures 7 to 10As shown, the bottom of the cement storage bin 21 and the fly ash storage bin 22 of the present invention is provided with a lower hopper 220, and the lower hopper 220 is provided with a discharge pipe 2201. The medium cement storage bin 21 and the fly ash storage bin 22 of the present invention are both provided with two lower hoppers 220 and a discharge pipe 2201, and the discharge pipe 2201 is evenly provided with a plurality of discharge ports 2202; the tops of the conveying cylinders 56 of the first dragon conveying mechanism 5 and the second dragon conveying mechanism 6 are provided with corresponding discharge ports 2202. The feed opening 561, the feed barrel 56 of each first dragon conveying mechanism 5 and the second dragon conveying mechanism 6 is placed in the discharge pipe 2201, and one end of the feed barrel 56 of each first dragon conveying mechanism 5 and the second dragon conveying mechanism 6 is connected to a push hydraulic cylinder 7; the push hydraulic cylinder 7 controls the feed barrel 56 to move back and forth in the discharge pipe 2201 by telescopic control, thereby controlling the discharge port 2202 to overlap or stagger with the feed opening 561, and then controlling the discharge or closing of the material. This improvement is conducive to the maintenance of the equipment in the later stage. For example, if the spiral inside the auger is damaged during use, the motor is damaged, etc. and needs to be replaced, but there is still material in the silo, the push hydraulic cylinder 7 is needed to push the feed barrel 56, so that the feed opening 561 does not overlap, and the non-open part of the feed barrel 56 just blocks the discharge port 2202, so that the hopper 220 can be closed, so as to facilitate the replacement of the equipment. Preferably, the number of the first dragon conveying mechanism 5 and the second dragon conveying mechanism 6 of the present invention is also 2, corresponding to the discharge pipe 2201.

[0043] In order to facilitate the telescopic and folding of the entire storage box 2, the storage box 2 of the present invention is a telescopic and foldable structure composed of multiple boxes, and the folding form is as follows: Figure 1 , Fig.10 This structure is consistent with the prior application of this application, see publication number: CN117601272A, title: A foldable modular concrete mixing plant, so it will not be repeated here. In this way, when transporting, it is convenient to fold the whole to reduce the volume and facilitate transportation.

[0044] The specific working principle of the present invention is as follows: After the equipment is installed, cement and fly ash are transported by air pumps. For example, during the cement feeding process, cement is pulled to the site and directly connected to the air pump device using the cement feeding pipe 210 to input the cement into the cement storage bin 21. Similarly, for fly ash feeding, the weight of the input cement or fly ash is recorded by the weighing sensor 3. During the feeding process, the dust gas generated is processed through the dust removal main pipe 4 and the dust removal water tank 11. If prefabricated cement fly ash mortar is required, the first dragon conveying mechanism 5 and the second dragon conveying mechanism are started in sequence. 6. The materials are transferred to the mixer 12. The weighing sensor 3 can record the materials in turn. After the cement and fly ash are loaded, the admixture adding mechanism 13 is started. After the admixture is weighed, it is transferred to the mixer 12. The waste water in the dust removal water tank 11 is pumped into the mixer 12 by a pump. According to the amount of water, the remaining water is added. Finally, the mixer 12 is started to mix the materials evenly until the required cement fly ash mortar is obtained. The prefabricated cement fly ash mortar is discharged through a pipeline and finally mixed with sand and stones to obtain concrete.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
