Description

Technical Field

[0001] This invention relates to the field of diatomaceous earth production technology, and in particular to an automatic batching equipment for diatomaceous earth production and its operating method. Background Technology

[0002] Diatomaceous earth wall covering is an environmentally friendly decorative wall material with diatomaceous earth as its main component. Its production process requires the precise mixing of various powdered or granular raw materials, such as diatomaceous earth, fillers, and additives, in specific proportions. Automated batching equipment can replace manual weighing, significantly improving batching efficiency and proportioning accuracy, and is a key device in modern diatomaceous earth wall covering production lines. Currently, common automated batching systems typically consist of multiple storage hoppers, weighing modules, conveyor screws, and mixers. They sequentially weigh each component and feed it into the mixing unit.

[0003] However, existing diatomaceous earth mud batching equipment still has the following shortcomings in use: First, the weighed materials are directly discharged, and some raw materials are prone to absorbing moisture and clumping. The lack of online dispersing or pulverizing functions makes subsequent mixing difficult and uneven. Second, multiple components often enter the mixer through the same discharge point after weighing, leading to material accumulation, increased mixing burden, and a tendency for component segregation. Third, the weighing and unloading drive mechanism is relatively complex, typically requiring each component to be equipped with a separate cylinder, motor, and other drive components, making it difficult to achieve multi-purpose functionality, resulting in a bulky overall structure and challenging collaborative control. These problems limit further improvements in the quality of diatomaceous earth mud batching and the optimization of production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic batching equipment and its operation method for diatomaceous earth production. By coordinating the weighing and discharging mechanism, the material conveying and mixing mechanism, and the crushing mechanism, the problem of material agglomeration and uneven mixing caused by concentrated material drop in the prior art is solved.

[0005] The technical solution of this invention is as follows: an automatic batching device for diatomaceous earth production, comprising a fixed plate, a feeding pipe fixedly connected to the top of the fixed plate, a batching tank disposed at the top of the feeding pipe, a mounting frame fixedly connected to the top of the fixed plate, a dual-shaft motor fixedly connected to one side of the mounting frame, and a mixing funnel fixedly connected to the bottom of the fixed plate; a weighing and discharging mechanism is provided in the inner cavity of the feeding pipe, the weighing and discharging mechanism comprising a weighing plate slidably connected to the inner side of the feeding pipe, a feeding trough opened on one side of the weighing plate, and an adjusting rod movably connected to one side of the weighing plate; a conveying and mixing mechanism is provided in the inner cavity of the fixed plate, the conveying and mixing mechanism comprising a fixed frame fixedly connected to the inner cavity of the fixed plate, and a conveying component disposed on the inner side of the fixed frame; a crushing mechanism is provided in the inner cavity of the feeding pipe, the crushing mechanism comprising a feeding bin fixedly connected to the inner cavity of the feeding pipe, and a crushing roller rotatably connected to the inner cavity of the feeding bin via a bearing seat.

[0006] Preferably, the weighing and discharging mechanism further includes a reciprocating lead screw fixedly connected to one of the output shafts of the dual-axis motor, a reciprocating lead sleeve sleeved on the surface of the reciprocating lead screw, an electromagnet fixedly connected to the surface of the reciprocating lead sleeve, a first slide rod fixedly connected to the top of the mounting bracket, a first slide sleeve slidably connected to the surface of the first slide rod, and a locking assembly disposed on the first slide sleeve.

[0007] Preferably, the engaging assembly includes a T-shaped rod fixedly connected to one side of the first sliding sleeve, a locking block slidably connected to the surface of the T-shaped rod, a spring sleeved on the surface of the T-shaped rod, and an adsorption block fixedly connected to the inside of the locking block.

[0008] Preferably, the other end of the adjusting rod is movably connected to one side of the first sliding sleeve, a fixing plate is fixedly connected to the surface of the mixing tank, and one end of the reciprocating screw is movably connected to the bottom of the fixing plate through a bearing seat.

[0009] Preferably, the weighing and discharging mechanism further includes a stirring rod fixedly connected to another output shaft of the dual-shaft motor, a spiral roller fixedly connected to one end of the stirring rod, a first gear fixedly connected to the other end of the stirring rod, a second gear meshing with the surface of the first gear, a first bevel gear fixedly connected to the second gear on the same axis, and a second bevel gear meshing with the surface of the first bevel gear.

[0010] Preferably, the conveying assembly includes a conveying roller rotatably connected to the inner side of the fixed frame via a bearing seat, a conveyor belt drivingly connected to the surface of the conveying roller, and a second bevel gear shaft fixedly connected to one of the conveying rollers.

[0011] Preferably, the number of the second gears is five, and they are arranged in a circular array, and a through slot is provided on the top of the fixed disk.

[0012] Preferably, the crushing mechanism further includes a second sliding sleeve fixedly connected to the bottom of the weighing plate, a second sliding rod slidably connected to the inner cavity of the second sliding sleeve, a connecting rod fixedly connected to the surface of the second sliding sleeve, a toothed plate fixedly connected to the other end of the connecting rod, and a drive gear meshing with one side of the toothed plate.

[0013] Preferably, one end of the crushing roller extends through to the outside of the feeding pipe and is fixedly connected to the shaft of the drive gear; one end of the second slide rod is fixedly connected to the surface of the feeding pipe; and the other end of the second slide rod is fixedly connected to the surface of the mounting bracket.

[0014] An operating method for an automatic batching device for diatomaceous earth production includes the following steps:

[0015] A; Before the equipment is started, the bottom valves of each batching tank are closed. The external controller of the control system sends instructions to the valves of each batching tank according to the preset diatom mud formula, opening the valves to allow the materials to fall onto the corresponding weighing plate. The built-in sensor of the weighing plate monitors the weight of the materials in real time. When the set value is reached, the controller closes the valve to ensure the accurate proportion of each component material. At this time, the locking blocks of all locking components are separated from the reciprocating thread sleeve under the action of the spring.

[0016] B; According to the formula sequence, the controller first energizes the electromagnet corresponding to the batching tank that needs to be discharged. The electromagnet attracts the adsorption block on the corresponding card block, so that the card block overcomes the spring force and engages with the reciprocating thread sleeve. Then the controller starts the dual-axis motor. One output shaft of the dual-axis motor drives the reciprocating screw to rotate, which cooperates with the engaged reciprocating thread sleeve to move it up and down. The reciprocating thread sleeve pulls the weighing plate to slide inward through the adjusting rod, so that the discharge chute enters the inner cavity of the discharge pipe. The weighed material falls into the discharge bin under the action of gravity.

[0017] C; As the weighing plate moves inward, the second sliding sleeve at its bottom drives the toothed plate to move through the connecting rod. The toothed plate drives the drive gear to rotate, which in turn drives the crushing roller to rotate at high speed. The material falling from the feed trough is immediately squeezed and crushed by the crushing roller, forming fine particles before continuing to fall, preventing agglomeration and creating conditions for subsequent uniform mixing.

[0018] D; The crushed material falls onto the surface of the conveyor belt. At this time, the output shaft of the other end of the dual-shaft motor drives the conveyor roller to rotate through the transmission chain of the first gear, the second gear, the first bevel gear and the second bevel gear, so that the conveyor belt runs continuously. Since the material from each feed pipe is received by the conveyor belt and transported laterally, a material layer is formed on the conveyor belt. The conveyor belt continuously feeds the material from the through groove of the fixed plate into the inner cavity of the mixing funnel at the end, avoiding excessive concentration of material in the mixing funnel and providing an excellent material distribution effect for the subsequent mixing process.

[0019] E; The output shaft at the other end of the dual-shaft motor simultaneously drives the stirring rod to rotate continuously inside the mixing funnel, which performs secondary stirring and mixing on the falling material. After being evenly mixed, the material is forced out of the discharge port of the mixing funnel by the push of the spiral roller at the bottom and enters the next process.

[0020] F; When the reciprocating thread sleeve completes a full reciprocating stroke (i.e., the weighing plate slides from the initial position into the discharge position and then slides back to the initial position), the controller cuts off the power to the electromagnet, and the locking block resets under the action of the spring, separating from the reciprocating thread sleeve. At this point, the discharge, crushing, conveying, and mixing process of one batching is completed, and it waits for the next weighing and discharge command. Through the above cycle, the equipment can efficiently, accurately, and automatically complete the batching task of large-scale diatom mud production.

[0021] The beneficial effects of this invention are as follows:

[0022] 1. This invention uses a built-in sensor on the weighing plate to monitor the weight of materials in real time, and an external controller to precisely control the opening and closing of the valves in the mixing tank. This ensures that each component is accurately proportioned according to the formula, with minimal error, thus guaranteeing stable quality of the diatomaceous earth product. When the weighing plate discharges material, it is linked to the crushing mechanism. The toothed plate drives the crushing roller to rotate at high speed, which immediately crushes and squeezes the falling material, effectively breaking up moisture-absorbing clumps and refining the particles. This lays the foundation for subsequent uniform mixing. The crushed material is then uniformly conveyed circumferentially to the mixing funnel by multiple sets of conveyor belts, avoiding the accumulation and component segregation caused by traditional centralized material discharge. At the same time, the stirring rod and the spiral roller work together to achieve dynamic secondary mixing and forced discharge, greatly improving mixing efficiency and uniformity.

[0023] 2. This invention requires only one dual-axis motor to synchronously drive the weighing, crushing, conveying, and mixing functions. By using a reciprocating screw and locking assembly to selectively control the independent discharge of each component, and by using gear and bevel gear transmission chains to link the conveyor belt and stirring mechanism, the drive structure is greatly simplified, reducing equipment costs and control complexity. The entire batching, crushing, conveying, and mixing process is automated, easy to operate, and suitable for high-precision production of large batches of diatomaceous earth.

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. The described embodiments are only some embodiments of the present invention, and not all embodiments.

[0038] Example 1

[0039] Please see Figures 1-11This is the first embodiment of the present invention, which provides an automatic batching device for diatomaceous earth production, including a fixed plate 1, a feeding pipe 2 fixedly connected to the top of the fixed plate 1, a batching tank 3 disposed at the top of the feeding pipe 2, a mounting frame 4 fixedly connected to the top of the fixed plate 1, a dual-shaft motor 5 fixedly connected to one side of the mounting frame 4, and a mixing funnel 6 fixedly connected to the bottom of the fixed plate 1; a weighing and discharging mechanism 7 is provided in the inner cavity of the feeding pipe 2, the weighing and discharging mechanism 7 including a weighing plate slidably connected to the inner side of the feeding pipe 2. 71, a feeding trough 72 is opened on one side of the weighing plate 71, and an adjusting rod 73 is movably connected to one side of the weighing plate 71; a material conveying and mixing mechanism 8 is provided in the inner cavity of the fixed plate 1, the material conveying and mixing mechanism 8 includes a fixed frame 81 fixedly connected to the inner cavity of the fixed plate 1, and a conveying assembly 82 disposed inside the fixed frame 81; a crushing mechanism 9 is provided in the inner cavity of the feeding pipe 2, the crushing mechanism 9 includes a feeding bin 91 fixedly connected to the inner cavity of the feeding pipe 2, and a crushing roller 92 rotatably connected to the inner cavity of the feeding bin 91 through a bearing seat.

[0040] The mixing tank 3, the feeding pipe 2, and the weighing and discharging mechanism 7 are preferably five sets, evenly arranged along the circumference of the fixed plate 1, which can respectively hold and process five different diatomaceous earth raw materials. The fixed plate 1 is a horizontally set circular structure with a large through hole in the center and a mixing funnel 6 fixedly connected to the bottom. The upper surface of the fixed plate 1 has a through groove 11 corresponding to each set of feeding pipes 2 for material to pass through. The feeding pipes 2 are vertically set and hollow inside. The weighing and discharging mechanism 7 is used to realize the weighing and discharging of each component. The weighing and controllable discharge of raw materials are achieved by the weighing plate 71 in the weighing and discharging mechanism 7, which is horizontally slidably set in the lower part of the inner cavity of the feeding pipe 2. It is used to carry materials and sense weight in real time. The initial position is that the weighing plate 71 closes the channel of the feeding pipe 2. The side of the weighing plate 71 near the center of the fixed plate 1 has a feeding trough 72. When the weighing plate 71 moves horizontally to the center for a certain distance, the feeding trough 72 enters the inner channel of the feeding pipe 2, so that the material can fall below through the feeding trough 72 and the through groove 11.

[0041] A feeding hopper 91 is fixed inside the feeding pipe 2 and below the weighing plate 71. The feeding hopper 91 is funnel-shaped and used to collect materials. The crushing roller 92 is rotatably installed inside the feeding hopper 91 through the bearing seat and is used to crush the falling materials. The fixed frame 81 in the conveying and mixing mechanism 8 is installed inside the fixed plate 1 and below the feeding pipe 2. The conveying and mixing mechanism 8 is used to centrally convey and continuously mix the weighed materials.

[0042] During operation, the materials in each batching tank 3 first fall onto the corresponding weighing plate 71 for precise weighing. Once the set weight is reached, the weighing and discharging mechanism 7 is activated, causing the weighing plate 71 to slide inward and open the discharge chute 72. During the material's descent, the crushing roller 92 of the crushing mechanism 9 rotates to crush the material. The crushed material falls onto the conveying component 82 of the conveying and mixing mechanism 8 and is uniformly conveyed circumferentially to the center. Finally, it is mixed in the mixing funnel 6 by the stirring rod 83 and discharged by the spiral roller 84. This achieves integrated operation of multi-component weighing, crushing, dispersing feeding, and mixing.

[0043] Example 2

[0044] Please see Figures 1-11 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0045] Specifically, the weighing and discharging mechanism 7 also includes a reciprocating lead screw 74 fixedly connected to one of the output shafts of the dual-axis motor 5, a reciprocating lead sleeve 75 sleeved on the surface of the reciprocating lead screw 74, an electromagnet 76 fixedly connected to the surface of the reciprocating lead sleeve 75, a first slide rod 77 fixedly connected to the top of the mounting bracket 4, a first slide sleeve 78 slidably connected to the surface of the first slide rod 77, and a locking assembly 79 provided on the first slide sleeve 78. The locking assembly 79 includes a T-shaped rod 791 fixedly connected to one side of the first slide sleeve 78, a locking block 792 slidably connected to the surface of the T-shaped rod 791, a spring 793 sleeved on the surface of the T-shaped rod 791, an adsorption block 794 fixedly connected to the inside of the locking block 792, and the other end of the adjusting rod 73 movably connected to one side of the first slide sleeve 78. A fixing plate 10 is fixedly connected to the surface of the mixing tank 3, and one end of the reciprocating lead screw 74 is movably connected to the bottom of the fixing plate 10 through a bearing seat.

[0046] The reciprocating screw 74 is arranged vertically, with its upper end rotatably connected to the fixed plate 10 via a bearing seat, and its lower end fixedly connected to the upper output shaft of the dual-axis motor 5. The reciprocating sleeve 75 is fitted on the reciprocating screw 74 and can move back and forth along its axial direction. Five electromagnets 76 are fixed on the outer circumference of the reciprocating sleeve 75, corresponding to five sets of feeding components. The first slide rod 77 is vertically fixed on the top of the mounting frame 4, and the first slide sleeve 78 is slidably fitted on the first slide rod 77. One end of the adjusting rod 73 is hinged to the weighing plate 71, and the other end is hinged to the first slide sleeve 78.

[0047] The engaging assembly 79 is disposed on each first sliding sleeve 78. A T-shaped rod 791 is fixed to the side of the first sliding sleeve 78 facing the reciprocating thread sleeve 75. A locking block 792 is slidably sleeved on the T-shaped rod 791. An adsorption block 794 is fixed inside the locking block 792. A spring 793 is sleeved on the T-shaped rod 791 and its two ends abut against the first sliding sleeve 78 and the locking block 792 respectively. In the natural state, the spring 793 pushes the locking block 792 away from the reciprocating thread sleeve 75, and the two do not contact each other. When it is necessary to unload a certain group of materials, the external controller energizes the electromagnet 76 corresponding to that group. The electromagnet 76 generates a magnetic force to attract the adsorption block 794 on the corresponding locking block 792, overcoming the elastic force of the spring 793, so that the locking block 792 is locked into the slot on the surface of the reciprocating thread sleeve 75. At this time, the first sliding sleeve 78 is linked with the reciprocating thread sleeve 75.

[0048] As the reciprocating screw 74 rotates, the reciprocating sleeve 75 moves up and down, driving the weighing plate 71 to move horizontally back and forth via the adjusting rod 73. This achieves precise unloading and resetting, while other unadsorbed locking blocks 792 remain disengaged, and the corresponding weighing plates 71 do not move. This selective locking drive method can control the independent movement of multiple weighing plates 71 with only one reciprocating screw 74, greatly simplifying the drive mechanism and making the batching operation flexible and reliable.

[0049] Example 3

[0050] Please see Figures 1-11 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0051] Specifically, the weighing and discharging mechanism 7 also includes a stirring rod 83 fixedly connected to another output shaft of the dual-shaft motor 5, a spiral roller 84 fixedly connected to one end of the stirring rod 83, a first gear 85 fixedly connected to the other end of the stirring rod 83, a second gear 86 meshing with the surface of the first gear 85, a first bevel gear 87 fixedly connected to the second gear 86 on the same axis, and a second bevel gear 88 meshing with the surface of the first bevel gear 87. The conveying assembly 82 includes a conveying roller 821 rotatably connected to the inner side of the fixed frame 81 through a bearing seat, a conveyor belt 822 drivingly connected to the surface of the conveying roller 821, and the second bevel gear 88 fixedly connected to one of the conveying rollers 821 at its shaft center. There are five second gears 86 arranged in a circumferential array. A through groove 11 is provided on the top of the fixed disk 1.

[0052] In the material conveying and mixing mechanism 8, the upper end of the stirring rod 83 is fixed to the lower output shaft of the dual-shaft motor 5 and extends downward to the inner cavity of the mixing funnel 6. The bottom of the stirring rod 83 is connected to the spiral roller 84. A first gear 85 is fixed on the upper part of the stirring rod 83. Five second gears 86 that mesh with the first gear 85 are arranged in a circumferential array around the first gear 85. Each second gear 86 is coaxially fixed to a first bevel gear 87. Each first bevel gear 87 meshes with a second bevel gear 88. The second bevel gear 88 is fixed to the shaft end of a conveying roller 821 of the corresponding conveying component 82. The five sets of conveying components 82 correspond to five raw materials and are arranged radially along the fixed disk 1. The conveying roller 821 and the conveyor belt 822 convey the material from the outer periphery to the center.

[0053] When the dual-shaft motor 5 drives the stirring rod 83 to rotate, the first gear 85 rotates synchronously, driving all the conveying rollers 821 to rotate through the second gear 86 and the bevel gear pair. This causes each conveyor belt 822 to continuously and evenly feed the crushed material into the circumference of the mixing funnel 6, forming a circumferentially dispersed feeding. The stirring rod 83 then stirs and mixes the concentrated material falling in. The spiral roller 84 pushes the mixture downwards and discharges it while stirring. This linkage structure ensures that the material is evenly distributed in the funnel, avoids the mixing dead zone caused by concentrated material falling in, and significantly improves the mixing uniformity and production efficiency.

[0054] Example 4

[0055] Please see Figures 1-11 This is the fourth embodiment of the present invention, which is based on the first three embodiments.

[0056] Specifically, the crushing mechanism 9 also includes a second sliding sleeve 93 fixedly connected to the bottom of the weighing plate 71, a second sliding rod 94 slidably connected to the inner cavity of the second sliding sleeve 93, a connecting rod 95 fixedly connected to the surface of the second sliding sleeve 93, a toothed plate 96 fixedly connected to the other end of the connecting rod 95, a drive gear 97 meshing with one side of the toothed plate 96, one end of the crushing roller 92 extending through to the outside of the feed pipe 2 and fixedly connected to the shaft of the drive gear 97, and one end of the second sliding rod 94 fixedly connected to the surface of the feed pipe 2, and the other end of the second sliding rod 94 fixedly connected to the surface of the mounting bracket 4.

[0057] The second slide rod 94 is arranged horizontally along the radial direction of the fixed plate 1. One end of it is fixed to the outer wall of the feed pipe 2, and the other end is fixed to the mounting bracket 4. The second slide sleeve 93 is fixed to the bottom of the weighing plate 71 and is slidably sleeved on the second slide rod 94. The upper end of the connecting rod 95 is fixed to the second slide sleeve 93, and the lower end is fixed to the horizontally arranged toothed plate 96. The toothed plate 96 meshes with the drive gear 97. The shaft end of the crushing roller 92 passes through the side wall of the feed pipe 2 and is coaxially fixed with the drive gear 97.

[0058] When the weighing plate 71 moves towards the center of the fixed plate 1 to unload material under the action of the adjusting rod 73, the second sliding sleeve 93 slides synchronously along the second sliding rod 94, and drives the toothed plate 96 to move linearly through the connecting rod 95. The toothed plate 96 drives the drive gear 97 to rotate, thereby driving the crushing roller 92 to rotate. During the process of the material falling from the feeding trough 72 into the feeding bin 91, the crushing roller 92 squeezes and shears it, breaking up the lumpy material and allowing it to continue falling in a fine state. This realizes the mechanical linkage between the unloading action and the crushing action. No additional power is required, and online crushing can be completed at the moment of weighing and unloading, effectively solving the problem of easy agglomeration of diatom mud raw materials.

[0059] An operating method for an automatic batching device for diatomaceous earth production includes the following steps:

[0060] A; Before the equipment is started, the bottom valves of each batching tank 3 are closed. The external controller of the control system sends instructions to the valves of each batching tank 3 according to the preset diatom mud formula, opening the valves to allow the material to fall onto the corresponding weighing plate 71. The built-in sensor of the weighing plate 71 monitors the weight of the material in real time. When the set value is reached, the controller closes the valve to ensure the accurate proportion of each component material. At this time, the locking blocks 792 of all locking components 79 are separated from the reciprocating thread sleeve 75 under the action of the spring 793.

[0061] B; According to the formula sequence, the controller first energizes the electromagnet 76 corresponding to the batching tank 3 that needs to be discharged. The electromagnet 76 attracts the adsorption block 794 on the corresponding card block 792, so that the card block 792 overcomes the elastic force of the spring 793 and engages with the reciprocating thread sleeve 75. Then the controller starts the dual-axis motor 5. One output shaft of the dual-axis motor 5 drives the reciprocating screw 74 to rotate, which cooperates with the engaged reciprocating thread sleeve 75 to move it up and down. The reciprocating thread sleeve 75 pulls the weighing plate 71 to slide inward through the adjusting rod 73, so that the discharge trough 72 enters the inner cavity of the discharge pipe 2. The weighed material falls into the discharge bin 91 under the action of gravity.

[0062] C; While the weighing plate 71 moves inward, the second sliding sleeve 93 at its bottom drives the toothed plate 96 to move through the connecting rod 95. The toothed plate 96 drives the drive gear 97 to rotate, which in turn drives the crushing roller 92 to rotate at high speed. The material falling from the feed trough 72 is immediately squeezed and crushed by the crushing roller 92, forming fine particles before continuing to fall, preventing agglomeration and creating conditions for subsequent uniform mixing.

[0063] D; The crushed material falls onto the surface of the conveyor belt 822. At this time, the output shaft of the other end of the dual-shaft motor 5 drives the conveyor roller 821 to rotate through the transmission chain of the first gear 85, the second gear 86, the first bevel gear 87 and the second bevel gear 88, so that the conveyor belt 822 runs continuously. Since the material from each feed pipe 2 is received and transported laterally by the conveyor belt 822, a material layer is formed on the conveyor belt 822. The conveyor belt 822 continuously feeds the material from the through groove 11 of the fixed plate 1 into the inner cavity of the mixing funnel 6 at the end, avoiding excessive concentration of material in the mixing funnel 6, and providing an excellent material distribution effect for the subsequent mixing process.

[0064] E; The output shaft of the other end of the dual-shaft motor 5 simultaneously drives the stirring rod 83 to rotate continuously in the mixing funnel 6, and performs secondary stirring and mixing on the falling material. After being evenly mixed, the material is forced out from the discharge port of the mixing funnel 6 by the push of the spiral roller 84 at the bottom, and enters the next process.

[0065] F; When the reciprocating thread sleeve 75 completes a full reciprocating stroke (i.e., the weighing plate 71 slides into the discharge position from the initial position and then slides back to the initial position), the controller cuts off the power supply to the electromagnet 76, and the locking block 792 is reset under the action of the spring 793 and separates from the reciprocating thread sleeve 75. At this point, the discharge, crushing, conveying and mixing process of one batching is completed, and it waits for the next weighing and discharge command.

10. An operating method for an automatic batching device for diatomaceous earth production, based on the automatic batching device for diatomaceous earth production according to any one of claims 1-9, characterized in that: Includes the following steps: A; Before the equipment is started, the bottom valves of each batching tank (3) are closed. The external controller of the control system sends instructions to the valves of each batching tank (3) according to the preset diatom mud formula, opens the valves so that the material falls onto the corresponding weighing plate (71). The built-in sensor of the weighing plate (71) monitors the weight of the material in real time. When the set value is reached, the controller closes the valve to ensure that the proportion of each component material is accurate. At this time, the locking blocks (792) of all locking components (79) are separated from the reciprocating thread sleeve (75) under the action of the spring (793). B; According to the formula sequence, the controller first energizes the electromagnet (76) corresponding to the batching tank (3) that needs to be discharged. The electromagnet (76) attracts the adsorption block (794) on the corresponding card block (792), so that the card block (792) overcomes the elastic force of the spring (793) and engages with the reciprocating thread sleeve (75). Then the controller starts the dual-axis motor (5). One output shaft of the dual-axis motor (5) drives the reciprocating screw (74) to rotate, which cooperates with the engaged reciprocating thread sleeve (75) to move it up and down. The reciprocating thread sleeve (75) pulls the weighing plate (71) to slide inward through the adjusting rod (73), so that the feeding trough (72) enters the inner cavity of the feeding pipe (2). The weighed material falls into the feeding bin (91) under the action of gravity. C; While the weighing plate (71) moves inward, the second sliding sleeve (93) at its bottom drives the toothed plate (96) to move through the connecting rod (95). The toothed plate (96) drives the drive gear (97) to rotate, which in turn drives the crushing roller (92) to rotate at high speed. The material falling from the feed trough (72) is immediately squeezed and crushed by the crushing roller (92) to form fine particles and continue to fall, preventing agglomeration and creating conditions for subsequent uniform mixing. D; The crushed material falls onto the surface of the conveyor belt (822). At this time, the output shaft of the other end of the dual-shaft motor (5) drives the conveyor roller (821) to rotate through the transmission chain of the first gear (85), the second gear (86), the first bevel gear (87) and the second bevel gear (88), so that the conveyor belt (822) runs continuously. Since the material from each feed pipe (2) is received by the conveyor belt (822) and transported laterally, a material layer is formed on the conveyor belt (822). The conveyor belt (822) continuously feeds the material from the through groove (11) of the fixed plate (1) into the inner cavity of the mixing funnel (6) at the end, avoiding excessive concentration of material in the mixing funnel (6), and providing excellent material distribution effect for the subsequent mixing process. E; The output shaft of the other end of the dual-shaft motor (5) simultaneously drives the stirring rod (83) to rotate continuously in the mixing funnel (6) to perform secondary stirring and mixing of the falling material. After being mixed evenly, the material is forced out of the discharge port of the mixing funnel (6) under the push of the spiral roller (84) at the bottom and enters the next process. F; When the reciprocating thread sleeve (75) completes a complete reciprocating stroke (i.e., the weighing plate (71) slides into the discharge position from the initial position and then slides back to the initial position), the controller cuts off the power supply of the electromagnet (76), and the locking block (792) is reset under the action of the spring (793) and separated from the reciprocating thread sleeve (75). At this point, the discharge, crushing, conveying and mixing process of one batching is completed, and it waits for the next weighing and discharge command. Through the above cycle, the equipment can efficiently, accurately and automatically complete the batching task of diatom mud production.
