Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] like Figures 1-6As shown, the present invention provides a technical solution: a continuous high-efficiency dry-mix mortar automatic pulping 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, and sand enters the sand drying device 1 through the feed hopper 101. The sand is heated and dried by a heater provided in the sand drying device 1, so that the moisture content of the sand is between 0.15% and 0.2%. A sand particle screener 2 is provided on one side of the sand drying device 1, and a spiral material conveyor 201 is connected between the sand drying device 1 and the sand particle screener 2. The dried sand is conveyed to the discharge port of the sand drying device 1 through the spiral blades in the sand drying device 1. Then the sand enters the sand particle screener 2 through the spiral material conveyor 201, and is screened into coarse sand and fine sand by the sand particle screener 2. In actual application, the sand particle screener 2 can separate the sand into three specifications of sand, for example, coarse sand, medium-sized sand and fine sand, wherein the fineness modulus of coarse sand is 3.1-3.7, the fineness modulus of medium-sized sand is 2.3-3.0 and the fineness modulus of fine sand is 1.6-2.2. In this solution, only coarse sand and fine sand are selected so that the fine sand can fill the gaps in the coarse sand, reducing the relative movement space of the coarse sand and increasing the internal friction. The medium-sized sand obtained by screening is discharged from the sand particle screener 2 and collected for standby use.

[0021] A dustproof housing 7 is provided on one side of the sand particle screener 2, and a conveying assembly is provided in the dustproof housing 7, wherein the conveying assembly includes a driving member, a plurality of rollers and a first conveyor belt 8. Along the conveying direction of the conveying assembly, a first sparging assembly and a second sparging assembly are respectively provided on the 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 provided on the top of the first sparging assembly, that is, the coarse sand storage tank 3 and the fine sand storage tank 4 are respectively located on the left and right sides of the first sparging assembly, and a coarse sand spiral conveyor is respectively 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. The conveyor 202 and the fine sand screw conveyor 203 are arranged along the conveying direction of the conveying component. A cement storage tank 5 and a filler storage tank 6 are respectively provided on the top of the second material refining component. The filler storage tank 6 is filled with 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 arranged on the left and right sides of the second material refining component. Valves are connected to the discharge pipes of the coarse sand storage tank 3, the fine sand storage tank 4, the cement storage tank 5 and the filler storage tank 6. The valves can be electric valves with controllable opening and closing degrees. In this way, the amount of material added in the corresponding tank body can be controlled by controlling the opening and closing degrees of the valves, thereby realizing continuous and efficient slurrying.

[0022] An anti-segregation telescopic tube 15 is provided on the discharge side of the first conveyor belt 8. The anti-segregation telescopic tube 15 is a mature existing technology and has been disclosed in the authorization announcement number CN218809222U, and the invention name is a dust-proof and anti-segregation telescopic discharge tube at the discharge end of a conveyor belt. Its function is to prevent the mortar from segregating and dispersing and stratifying due to the existence of height difference. The mortar is unloaded through the anti-segregation telescopic tube 15.

[0023] like Figure 2 and Figure 3 As shown, the first material sparging assembly and the second material sparging assembly each include a plurality of rotating shafts 111, a second conveyor belt 112 is connected between the rotating shafts 111, a first connecting shaft 114 and a first supporting shaft 115 are fixed to the inner wall of one side of the dustproof housing 7, a first material guide plate 116 is movably connected to the shaft body of the first connecting shaft 114, the first supporting shaft 115 is located at the bottom of the first material guide plate 116 and contacts the first material guide plate 116, a second connecting shaft 117 and a second supporting shaft 118 are fixed to the inner wall of the other side of the dustproof housing 7, A second guide plate 119 is movably connected to the shaft, the second support shaft 118 is located at the bottom of the second guide plate 119 and contacts the second guide plate 119, the first guide plate 116 is located at the top of one side of the second conveyor belt 112, and the second guide plate 119 is located directly below the second conveyor belt 112. A pushing member is provided at the bottom of the second conveyor belt 112, which drives the first guide plate 116 and the second guide plate 119 to vibrate, so that the material passes through the first guide plate 116 and the second guide plate 119 and falls evenly onto the first conveyor belt 8.

[0024] Among them, the pushing member includes two fixed plates 1110 fixed to the side walls of the dustproof shell 7, a plurality of guide rods 1111 are fixed between the two fixed plates 1110, and the movable plate 1112 is movably plugged into the rod body of the guide rod 1111, a plurality of springs 1113 are fixed between one of the fixed plates 1110 and the movable plate 1112, and a first pressure rod 1114 and a second pressure rod 1115 are fixed on both sides of the movable plate 1112 respectively, and the first pressure rod 1114 and the second pressure rod 1115 are movably plugged into the fixed plates 1110 on both sides respectively, and one side rod body of the first pressure rod 1114 and the second pressure rod 1115 respectively extends to the bottom of the first guide plate 116 and the second guide plate 119, and a plurality of equidistantly distributed blocking rods 113 are fixed on the belt body of the second conveyor belt 112, and the top plate body of the movable plate 1112 is pushed by the blocking rod 113, as shown in FIG. Figure 3As shown, when the baffle 113 pushes the top plate of the movable plate 1112, the spring 1113 contracts. When the baffle 113 loses contact with the top plate of the movable plate 1112, under the elastic force of the spring 1113, the first pressure rod 1114 and the second pressure rod 1115 move horizontally to the 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 passes through the first guide plate 116 and the second guide plate 119 and falls evenly onto the first conveyor belt 8.

[0025] In this solution, the first material guide plate 116 in the first material leveling assembly is located directly below the outlet of the coarse sand storage tank 3, and the first material guide plate 116 in the second material leveling assembly is located directly below the outlet of the cement storage tank 5. Correspondingly, the second conveyor belt 112 in the first material leveling assembly is located directly below the outlet of the fine sand storage tank 4, and the second conveyor belt 112 in the second material leveling assembly is located directly below the outlet of the filler storage tank 6. In this way, the cross-section of the mortar is coarse sand, fine sand, cement and filler from bottom to top.

[0026] like Figure 4 As shown, a first water pipe 12 is fixed in the dustproof shell 7, and the first water pipe 12 is located between the first sizing assembly and the second sizing assembly, and a connecting pipe 122 is connected to the pipe body of the first water pipe 12, and a plurality of downward-inclined first mist nozzles 121 are fixedly connected to the bottom pipe body of the first water pipe 12. The function of the first mist nozzle 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 water spraying amount of the first mist nozzle 121 through data such as the target moisture content and the number of the first mist nozzles 121. Among them, 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 materials such as cement and filler in the subsequent mixing process, thereby improving the uniformity and stability of the dry-mixed mortar, because sand with an appropriate moisture content can more effectively bond cement and filler particles when mixed with other materials, reduce friction and sliding between particles, and make the materials more tightly bonded, thereby improving the overall quality of the dry-mixed mortar.

[0027] like Figure 4As shown, a movable shaft 131 is movably connected to the inner wall of the dustproof housing 7, and a plurality of through holes equidistantly arranged are opened on the top of the dustproof housing 7, and a fan head 132 is installed in the through hole. A horizontal plate 135 is fixed to the inner wall of the dustproof housing 7, and 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 rod body of each connecting rod 133, and a plurality of worms equal to the number of worm gears 134 are formed on the shaft body of the movable shaft 131. The worm and the worm gear 134 are meshed for transmission. When the worm gear 134 rotates, the connecting rod 133 is driven to rotate. When the connecting rod 133 rotates, the fan blades of the fan head 132 are driven to rotate, thereby making the inner cavity of the dustproof housing 7 A negative pressure is formed, and the dust in the dustproof shell 7 is discharged through the fan head 132. A second water pipe 136 is provided on the top of the dustproof shell 7, and the connecting pipe 122 is fixedly connected to the second water pipe 136. A plurality of second mist nozzles 137 are fixedly connected to the pipe body of the second water pipe 136, and the spray port of the second mist nozzle 137 is facing the side of the fan head 132. A water pump and a water pool are connected to the pipe body of the second water pipe 136. The water pump pumps the water in the water pool into the second water pipe 136 and then enters the first water pipe 12 through the connecting pipe 122. Finally, it is atomized and sprayed 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.

[0028] like Figure 1 、 Figure 3 and Figure 4 As shown, the driving part 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 pulley 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, the tensioning pulley 10, the first pulley 9, the two second pulleys 902 and the third pulley 903 are driven to rotate through the belt 901.

[0029] like Figure 2 、 Figure 5 and Figure 6As shown, a turning assembly 14 is provided on the outside of the second material-splitting assembly, and the conveyed dry-mixed mortar is turned over by the turning assembly 14, wherein the turning assembly 14 includes a top plate 143 fixed to the inner wall of the dustproof shell 7, and a plurality of transversely distributed front mixing blocks 141 are fixed to the bottom end of the top plate 143. When viewed from above, the front mixing block 141 is triangular, that is, an inwardly contracted material receiving head 1401 is formed at the front of the front mixing block 141, and an outwardly expanded back material head 1402 is formed at the rear of the front mixing block 141. Both sides of the front mixing block 141 are formed with outwardly curved slope surfaces 1403. In this way, When the mortar moves along the first conveyor belt 8, the mortar moves outward along the slope surface 1403 and disperses rearward and outward at the back head 1402, so that the mortar is turned over during the conveying process, thereby increasing the mixing uniformity of the dry-mixed mortar. In order to further improve the mixing uniformity of the dry-mixed mortar, in this solution, along the conveying direction of the conveying component, a number of rear mixing blocks 142 with the same specifications as the front mixing blocks 141 are fixed at the bottom end of the other side of the top plate 143, wherein the rear mixing block 142 is located between two adjacent front mixing blocks 141, thereby realizing the maximum range of turning of the mortar during the conveying process.

[0030] During operation, the controller drives the components to put sand into the feed hopper 101 and add cement and filler into the cement storage tank 5 and filler storage tank 6 respectively. The sand enters the sand drying device 1 from the feed hopper 101, and the dried sand is sent to the sand particle screener 2 through the spiral material conveyor 201. The coarse sand and fine sand after screening enter the corresponding storage tanks through the coarse sand spiral conveyor 202 and the fine sand spiral conveyor 203 respectively. The amount of material added to the corresponding tank body is controlled by controlling the opening and closing degree of the valve. The first mist nozzle 121 on the first water pipe 12 sprays water mist to the sand to increase the moisture content to meet the subsequent mixing requirements. The dust suction system composed of the fan head 132 and the movable shaft 131 forms a negative pressure in the dustproof shell 7 to discharge dust. At the same time, the second mist nozzle 137 discharges dust and reduces dust.

[0031] Under the action of the first refining assembly and the second refining assembly, the mortar on the first conveyor belt 8 is successively flat coarse sand, fine sand, cement and filler. Since the fine sand can fill the gaps in the coarse sand, the relative movement space of the coarse sand is reduced and the internal friction is increased, so that the cement and filler can be located above the coarse sand and fine sand, which is easier to fully mix subsequently.

[0032] As the mortar moves, the dry-mixed mortar being transported is turned over by the front mixing block 141 and the rear mixing block 142 of the turning assembly 14 to improve the mixing uniformity. Finally, the mortar is unloaded and bagged through the anti-segregation telescopic tube 15.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is limited by the accompanying embodiments and their equivalents.
