Description

Technical Field

[0001] This invention relates to the field of mortar preparation technology, specifically to a continuous, high-efficiency, automatic dry-mixed mortar preparation equipment. Background Technology

[0002] Dry-mixed mortar is the most widely used type of premixed mortar and represents the ultimate direction for the development of green building materials. It refers to a granular or powdery substance formed by physically mixing aggregates (such as yellow sand), cementitious materials (such as cement and fly ash), and admixtures (such as polymers) in a certain proportion.

[0003] Chinese invention patent application publication number CN109049346A discloses a fully automatic method for preparing premixed dry mortar. Its advantages are: the sand used as raw material is dried and screened first, which is conducive to producing higher quality premixed products; the metering device used can adjust the weight of each component of the premix, thereby improving the batching accuracy and obtaining a mixture that meets the set ratio requirements.

[0004] For example, Chinese invention patent application publication number CN112976315A discloses a dry-mixed mortar production system, which includes aggregate bins, binder bins, and admixture bins. Each bin is equipped with an electric discharge gate at its bottom discharge port. It has the advantages of saving materials, automation, and high-quality finished products. It is mainly used for the production of dry-mixed mortar.

[0005] Existing dry-mixed mortar preparation equipment still has certain defects in practical applications. For example, during the preparation of the mortar, the heavy sand in the batching causes stratification during bagging and transportation. When the dry-mixed mortar is transported to the construction site and mixed with water, the mixing time needs to be increased to ensure that the mortar is mixed evenly, thereby reducing construction efficiency. Summary of the Invention

[0006] The purpose of this invention is to provide a continuous, high-efficiency, automatic dry-mixed mortar preparation equipment to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a continuous high-efficiency dry-mixed mortar automatic slurry preparation equipment, including a sand drying device and a feeding hopper, wherein a sand particle screen is provided on one side of the sand drying device, and a screw material conveyor is connected between the sand drying device and the sand particle screen.

[0009] Along the conveying direction of the conveying component, the top of the first uniform material component is respectively provided with a coarse sand storage tank and a fine sand storage tank. A coarse sand screw conveyor is connected between the coarse sand outlet of the sand particle screen and the coarse sand storage tank, and a fine sand screw conveyor is connected between the fine sand outlet of the sand particle screen and the fine sand storage tank.

[0010] Along the conveying direction of the conveying component, the top of the second uniform material assembly is respectively equipped with a cement storage tank and a filler storage tank, and valves are connected to the discharge pipes of the coarse sand storage tank, fine sand storage tank, cement storage tank and filler storage tank.

[0011] The discharge side of the first conveyor belt is equipped with an anti-segregation telescopic pipe.

[0012] Furthermore, both the first and second material leveling components include several rotating shafts, and a second conveyor belt is connected between the rotating shafts.

[0013] A first connecting shaft and a first supporting shaft are fixed to the inner wall of one side of the dustproof housing. A first guide plate is movably connected to the shaft of the first connecting shaft. The first supporting shaft is located at the bottom of the first guide plate and is in contact with the first guide plate.

[0014] A second connecting shaft and a second supporting shaft are fixed to the inner wall of the other side of the dustproof housing. A second guide plate is movably connected to the shaft of the second connecting shaft. The second supporting shaft is located at the bottom of the second guide plate and is in contact with the second guide plate. The second guide plate is located directly below the second conveyor belt.

[0015] A pusher is installed at the bottom of the second conveyor belt.

[0016] Furthermore, the pusher includes two fixed plates, a plurality of guide rods are fixed between the two fixed plates, a movable plate is movably inserted into the rod body of the guide rod, and a spring is fixed between one of the fixed plates and the movable plate;

[0017] The movable plate is fixed with a first pressing rod and a second pressing rod on both sides respectively, and the first pressing rod and the second pressing rod are movably inserted into the fixed plates on both sides respectively;

[0018] The second conveyor belt has several equally spaced baffles fixed on it, which push the top plate of the movable plate.

[0019] Furthermore, the inner wall of the dustproof housing is movably connected to a movable shaft, the top of the dustproof housing has several through holes, a fan head is installed in the through holes, a horizontal plate is fixed to the inner wall of the dustproof housing, a connecting rod is fixed to the bottom of the fan head, when the connecting rod rotates, it drives the fan blades of the fan head to rotate, thereby creating a negative pressure in the inner cavity of the dustproof housing, and a worm gear is fixed on the bottom of the connecting rod.

[0020] Several worms are formed on the shaft of the movable shaft, and the worms mesh with the worm wheel.

[0021] Furthermore, the driving component includes a motor, a tensioning wheel, a first pulley fixed on a shaft on one side of the roller, a second pulley fixed on a shaft on one side of the rotating shaft, and a third pulley fixed on a shaft on one side of the movable shaft.

[0022] The tension pulley, the first pulley, the second pulley, and the third pulley are connected to belts, and the output end of the motor is fixed to the end of the roller.

[0023] Furthermore, a first water pipe is fixed inside the dustproof housing. The first water pipe is located between the first and second material leveling components. A connecting pipe is connected to the body of the first water pipe, and several downwardly tilted first mist nozzles are fixedly connected to the bottom of the first water pipe.

[0024] Furthermore, a second water pipe is provided on the top of the dustproof shell, the first water pipe and the second water pipe are fixedly connected, and a water pump is connected to the body of the second water pipe;

[0025] Several second mist nozzles are fixedly connected to the body of the second water pipe, with the spray nozzles of the second mist nozzles facing the fan head.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] This continuous, high-efficiency, automatic dry-mixed mortar preparation equipment is equipped with a sand particle screen, a coarse sand storage tank, a fine sand storage tank, a cement storage tank, a filler storage tank, a first uniform mixing component, a second uniform mixing component, and an anti-segregation expansion tube. Under the action of the first and second uniform mixing components, the mortar on the first conveyor belt consists of coarse sand, fine sand, cement, and filler laid out in sequence. Because the fine sand can fill the gaps between the coarse sand, it reduces the relative movement space of the coarse sand and increases the internal friction, thereby allowing the cement and filler to be located on top of the coarse and fine sand. The dry-mixed mortar is stacked in the above-mentioned layered structure in the packaging bag through the anti-segregation expansion tube, reducing the stratification phenomenon that occurs during bagging and transportation after the mortar is prepared, and reducing the mixing time of the mortar and water in the later stage, thereby improving the construction efficiency.

[0028] At the same time, a first water pipe and several first mist nozzles are installed to increase the moisture content of the sand, so that the sand can better combine with cement, fillers and other materials in the subsequent mixing process, reduce the friction and sliding between material particles, make the material bond more compact, improve the uniformity and stability of dry-mixed mortar, and thus improve the overall quality of dry-mixed mortar.

[0029] Furthermore, the device is equipped with a fan head, a movable shaft, a worm gear, and a worm wheel. While increasing the moisture content of the sand, the water mist sprayed through the second mist nozzle suppresses the dust discharged through the fan head, reducing the dust pollution caused to the environment when the device is used for dry-mixed mortar preparation.

Detailed Implementation

[0037] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] like Figures 1-6As shown, the present invention provides a technical solution: a continuous high-efficiency automatic dry-mixed mortar preparation equipment, including a sand drying device 1 and a feed hopper 101. The feed hopper 101 is located on the feeding side of the sand drying device 1. Sand enters the sand drying device 1 through the feed hopper 101 and is heated and dried by a heater installed inside the sand drying device 1, so that the moisture content of the sand is between 0.15% and 0.2%. A sand particle screen 2 is installed on one side of the sand drying device 1. A screw conveyor 201 connects the sand drying device 1 and the sand particle screen 2. The dried sand is conveyed to the discharge port of the sand drying device 1 through the spiral blades inside the sand drying device 1. Then, the sand enters the sand particle screener 2 through the screw conveyor 201. The sand particle screener 2 separates the sand into coarse sand and fine sand. In practical applications, the sand particle screener 2 can separate sand into three specifications, such as coarse sand, medium-sized sand and fine sand. The fineness modulus of coarse sand is 3.1-3.7, that of medium-sized sand is 2.3-3.0 and that of fine sand is 1.6-2.2. In this scheme, only coarse sand and fine sand are selected so that the fine sand can fill the gaps in the coarse sand, reduce the relative movement space of the coarse sand, and increase the internal friction. The medium-sized sand obtained by screening is discharged from the sand particle screener 2 and collected for later use.

[0039] A dustproof housing 7 is provided on one side of the sand particle screener 2. A conveying assembly is installed inside the dustproof housing 7. The conveying assembly includes a drive unit, several rollers, and a first conveyor belt 8. Along the conveying direction of the conveying assembly, a first leveling assembly and a second leveling assembly are respectively installed on top of the first conveyor belt 8. Along the conveying direction of the conveying assembly, a coarse sand storage tank 3 and a fine sand storage tank 4 are respectively installed on top of the first leveling assembly, i.e., the coarse sand storage tank 3 and the fine sand storage tank 4 are located on the left and right sides of the first leveling assembly, respectively. Coarse sand spiral conveyors are connected between the coarse sand outlet of the sand particle screener 2 and the coarse sand storage tank 3, and between the fine sand outlet of the sand particle screener 2 and the fine sand storage tank 4, respectively. The conveyor 202 and the fine sand screw conveyor 203 are connected along the conveying direction of the conveying components. The top of the second uniform material assembly is respectively equipped with a cement storage tank 5 and a filler storage tank 6. The filler storage tank 6 contains one or more mixtures of additives such as mineral powder, fly ash, or thickening powder. Similarly, the cement storage tank 5 and the filler storage tank 6 are respectively located on the left and right sides of the second uniform material assembly. Valves are connected to the discharge pipes of the coarse sand storage tank 3, fine sand storage tank 4, cement storage tank 5, and filler storage tank 6. The valves can be electric valves with controllable opening and closing. In this way, the amount of material added to the corresponding tank can be controlled by controlling the opening and closing of the valves, so as to achieve continuous and efficient pulping.

[0040] An anti-segregation telescopic pipe 15 is provided on the discharge side of the first conveyor belt 8. The anti-segregation telescopic pipe 15 is a mature existing technology, which has been disclosed in the authorized announcement number CN218809222U, invention titled "A Dustproof and Anti-Segregation Telescopic Discharge Pipe for Conveyor Belt Discharge End". Its function is to prevent the mortar from segregating and dispersing due to the existence of height difference. The mortar is discharged through the anti-segregation telescopic pipe 15.

[0041] like Figure 2 and Figure 3 As shown, both the first and second material leveling components include several rotating shafts 111. A second conveyor belt 112 is connected between the rotating shafts 111. A first connecting shaft 114 and a first support shaft 115 are fixed to the inner wall of one side of the dustproof housing 7. A first guide plate 116 is movably connected to the shaft of the first connecting shaft 114. The first support shaft 115 is located at the bottom of the first guide plate 116 and in contact with the first guide plate 116. A second connecting shaft 117 and a second support shaft 118 are fixed to the inner wall of the other side of the dustproof housing 7. The second connecting shaft 117... A second guide plate 119 is movably connected to the shaft. A second support shaft 118 is located at the bottom of the second guide plate 119 and in contact with the second guide plate 119. A first guide plate 116 is located at the top of one side of the second conveyor belt 112, while the second guide plate 119 is located directly below the second conveyor belt 112. A pusher is provided at the bottom of the second conveyor belt 112. The pusher drives the first guide plate 116 and the second guide plate 119 to vibrate, so that the material falls evenly onto the first conveyor belt 8 through the first guide plate 116 and the second guide plate 119.

[0042] The pushing component includes two fixed plates 1110 fixed to the side wall of the dustproof housing 7. Several guide rods 1111 are fixed between the two fixed plates 1110. A movable plate 1112 is movably inserted into the rods of the guide rods 1111. Several springs 1113 are fixed between one of the fixed plates 1110 and the movable plate 1112. A first pressing rod 1114 and a second pressing rod 1115 are fixed to both sides of the movable plate 1112, respectively. The first pressing rod 1114 and the second pressing rod 1115 are movably inserted into the fixed plates 1110 on both sides. One side of the first pressing rod 1114 and the second pressing rod 1115 extends to the bottom of the first guide plate 116 and the second guide plate 119, respectively. Several equally spaced baffles 113 are fixed on the belt of the second conveyor belt 112. The baffles 113 push the top plate of the movable plate 1112. Figure 3As shown, when the stop bar 113 pushes the top plate of the movable plate 1112, the spring 1113 contracts. When the stop bar 113 disengages from the top plate of the movable plate 1112, under the elastic force of the spring 1113, the first pressing bar 1114 and the second pressing bar 1115 move laterally left and right, thereby continuously pushing the first guide plate 116 and the second guide plate 119, causing the first guide plate 116 and the second guide plate 119 to vibrate, so that the material falls evenly onto the first conveyor belt 8 through the first guide plate 116 and the second guide plate 119.

[0043] In this scheme, the first guide plate 116 in the first uniform material assembly is located directly below the outlet of the coarse sand storage tank 3, and the first guide plate 116 in the second uniform material assembly is located directly below the outlet of the cement storage tank 5. Correspondingly, the second conveyor belt 112 in the first uniform material assembly is located directly below the outlet of the fine sand storage tank 4, and the second conveyor belt 112 in the second uniform material assembly is located directly below the outlet of the filler storage tank 6. Thus, the mortar cross-section from bottom to top consists of coarse sand, fine sand, cement, and filler.

[0044] like Figure 4 As shown, a first water pipe 12 is fixed inside the dustproof housing 7, and the first water pipe 12 is located between the first and second uniform material components. A connecting pipe 122 is connected to the pipe body of the first water pipe 12. Several downwardly inclined first mist nozzles 121 are fixedly connected to the bottom of the first water pipe 12. The function of the first mist nozzles 121 is to spray water mist into the dry sand to increase the moisture content of the sand. Those skilled in the art can calculate the spray volume of the first mist nozzles 121 by using data such as the target moisture content and the number of first mist nozzles 121. The target moisture content of the sand is between 0.5% and 1%. The purpose of increasing the moisture content of the sand is to enable the sand to better combine with cement, fillers and other materials in the subsequent mixing process, thereby improving the uniformity and stability of the dry-mixed mortar. Because sand with a suitable moisture content can more effectively bond cement and filler particles when mixed with other materials, reduce friction and sliding between particles, and make the bonding between materials tighter, thereby improving the overall quality of the dry-mixed mortar.

[0045] like Figure 4As shown, a movable shaft 131 is movably connected to the inner wall of the dustproof housing 7. Several equidistant through holes are opened at the top of the dustproof housing 7, and a fan head 132 is installed in each through hole. A horizontal plate 135 is fixed to the inner wall of the dustproof housing 7. A connecting rod 133, rotatably connected to the horizontal plate 135, is fixed to the bottom of the fan head 132. A worm gear 134 is fixed to the bottom of each connecting rod 133. Several worms, equal in number to the worm gears 134, are formed on the shaft of the movable shaft 131. The worms mesh with the worm gears 134 for transmission. When the worm gears 134 rotate, they drive the connecting rods 133 to rotate. When the connecting rods 133 rotate, they drive the fan blades of the fan head 132 to rotate, thereby causing the inner cavity of the dustproof housing 7 to... A negative pressure is created, and the dust inside the dustproof housing 7 is discharged through the fan head 132. A second water pipe 136 is provided on the top of the dustproof housing 7, and the connecting pipe 122 is fixedly connected to the second water pipe 136. Several second mist nozzles 137 are fixedly connected to the pipe body of the second water pipe 136, and the spray nozzles of the second mist nozzles 137 face the side of the fan head 132. A water pump and a water tank are connected to the pipe body of the second water pipe 136. The water pump draws water from the water tank into the second water pipe 136 and then enters the first water pipe 12 through the connecting pipe 122. Finally, the water is atomized and sprayed out through the first mist nozzle 121 and the second mist nozzle 137. The water mist sprayed by the second mist nozzle 137 reduces the dust discharged through the fan head 132.

[0046] like Figure 1 , Figure 3 and Figure 4 As shown, the driving component includes a motor, a tensioning pulley 10, a first pulley 9, two second pulleys 902 and a third pulley 903. A belt 901 is connected to the tensioning pulley 10, the first pulley 9, the second pulleys 902 and the third pulley 903. The output end of the motor is fixed to the end of the roller. After the motor is started, it drives the tensioning pulley 10, the first pulley 9, the two second pulleys 902 and the third pulley 903 to rotate through the belt 901.

[0047] like Figure 2 , Figure 5 and Figure 6As shown, a turning component 14 is provided on the outside of the second uniform material assembly. The turning component 14 turns the conveyed dry-mixed mortar. The turning component 14 includes a top plate 143 fixed to the inner wall of the dustproof shell 7. Several horizontally distributed front mixing blocks 141 are fixed at the bottom of the top plate 143. In the top view, the front mixing blocks 141 are triangular, that is, an inwardly contracting material-welcoming head 1401 is formed at the front of the front mixing block 141, an outwardly expanding material-backing head 1402 is formed at the rear of the front mixing block 141, and outwardly curved slope surfaces 1403 are formed on both sides of the front mixing block 141. As the mortar moves along the first conveyor belt 8, it moves outward along the slope 1403. At the back material head 1402, the mortar is dispersed backward and outward, causing it to tumble during the conveying process and increasing the uniformity of the dry-mixed mortar. To further improve the uniformity of the dry-mixed mortar, in this scheme, along the conveying direction of the conveying component, several rear mixing blocks 142 with the same specifications as the front mixing blocks 141 are fixed at the bottom of the other side of the top plate 143. The rear mixing blocks 142 are located between two adjacent front mixing blocks 141, thereby maximizing the tumbling of the mortar during the conveying process.

[0048] During operation, the controller drives the sand to be fed into the feed hopper 101 and the cement and filler to be added to the cement storage tank 5 and the filler storage tank 6, respectively. The sand enters the sand drying device 1 from the feed hopper 101. The dried sand is sent to the sand particle screener 2 via the screw conveyor 201. The screened coarse sand and fine sand enter the corresponding storage tanks via the coarse sand screw conveyor 202 and the fine sand screw conveyor 203, respectively. The amount of material added to the corresponding tank is controlled by controlling the opening and closing of the valve. The first mist nozzle 121 on the first water pipe 12 sprays water mist onto the sand to increase the moisture content and meet the subsequent mixing requirements. The dust collection system composed of the fan head 132 and the movable shaft 131 creates a negative pressure inside the dustproof shell 7 to discharge dust. At the same time, the second mist nozzle 137 reduces the dust discharged.

[0049] Under the action of the first and second uniform material components, the mortar on the first conveyor belt 8 consists of coarse sand, fine sand, cement and filler laid flat in sequence. Since the fine sand can fill the gaps between the coarse sand, it reduces the relative movement space of the coarse sand and increases the internal friction, so that the cement and filler can be located on top of the coarse sand and fine sand, making it easier to mix them thoroughly in the subsequent process.

[0050] As the mortar moves, the front mixing block 141 and rear mixing block 142 of the material turning component 14 turn the conveyed dry-mixed mortar to improve the mixing uniformity. Finally, the mortar is unloaded and bagged through the anti-segregation expansion tube 15.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended embodiments and their equivalents.
