Description

Technical Field

[0001] This utility model relates to the field of chemical solution preparation technology, specifically a chemical solution preparation and control system. Background Technology

[0002] Chemical solution preparation refers to adding multiple liquids or liquid and solids in a certain proportion to the same container for mixing to form a prepared mixture. The mixture is then stirred using a stirring device to form a chemical solution. In the process of chemical solution preparation, the volume of liquids and the weight of solids are usually precisely controlled by a preparation control device to achieve a precise preparation effect.

[0003] Currently, during the mixing and blending of liquids and solids, when the blending control device controls the weighing and metering of raw materials, some solid powder or solid particles tend to remain on the inner wall of the falling pipe. This causes the weight data of the raw materials in the container to be slightly below the standard. After calculation, when the corresponding missing amount is added, the remaining solid powder or solid particles tend to fall into the container along with the missing solid powder or solid particles, which can easily cause a slight over-standard in the weighing data, thus affecting the accuracy of subsequent chemical solution blending.

[0004] Therefore, this utility model provides a chemical solution preparation and control system. Utility Model Content

[0008] To achieve the above objectives, this utility model provides the following technical solution: a chemical solution preparation control system, including a mounting frame, a preparation control terminal fixedly connected to the top of the mounting frame, a pair of storage cylinders embedded in the top of the mounting frame, and a discharge pipe fixedly connected to the bottom of each pair of storage cylinders, a shaking mechanism provided between the inner top of the mounting frame and the outer wall of the pair of discharge pipes, an electric control valve installed on the outer wall of each pair of discharge pipes, and a sealing cover plate sleeved between the bottom ends of the pair of discharge pipes, a pair of sliding cylinders fixedly connected to the inner wall of the mounting frame, and a flat plate weighing device fixedly connected between the output ends of the pair of sliding cylinders, a measuring cylinder placed on the top of the flat plate weighing device, and a clamping and fixing mechanism provided between the outer wall of the measuring cylinder and the top of the flat plate weighing device, and an insertion mechanism provided between the bottom end of the sealing cover plate and the top end of the measuring cylinder, wherein the electric control valve, the sliding cylinder, and the flat plate weighing device are all electrically connected to the preparation control terminal.

[0009] The clamping and fixing mechanism described above includes a pair of telescopic cylinders, both of which are fixedly connected to the top of the flat plate weigher, and both of the output ends of the pair of telescopic cylinders are fixedly connected to clamping plates.

[0010] As mentioned above, both of the clamps are arc-shaped, and both of the clamps have an anti-slip layer on their surfaces.

[0011] The aforementioned shaking mechanism includes a hanger fixedly connected to the top of the mounting frame. An electric telescopic rod is fixedly connected to the bottom of the hanger, and the electric telescopic rod is electrically connected to a control terminal. A cross plate is fixedly connected to the top of the electric telescopic rod, and both ends of the cross plate are slidably connected to the inner wall of the hanger. A pair of spring plates are fixedly connected between the bottom of the cross plate and the bottom of the hanger. A pair of movable rods are fixedly connected to the bottom of the cross plate, and a pair of round holes are drilled in the bottom of the hanger.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] like Figure 1-4As shown, this utility model provides a technical solution: a chemical solution preparation control system, including a mounting frame 1, a preparation control terminal 2 fixedly connected to the top of the mounting frame 1, a pair of storage cylinders 3 embedded in the top of the mounting frame 1, and a discharge pipe 4 fixedly connected to the bottom of each pair of storage cylinders 3, a shaking mechanism 11 provided between the inner top of the mounting frame 1 and the outer wall of the pair of discharge pipes 4, an electric control valve 5 installed on the outer wall of each pair of discharge pipes 4, and a sealing cover plate 6 sleeved between the bottom ends of the pair of discharge pipes 4, a pair of sliding cylinders 7 fixedly connected to the inner wall of the mounting frame 1, and a flat plate weighing device 9 fixedly connected between the output ends of the pair of sliding cylinders 7, a measuring cylinder 8 placed on the top of the flat plate weighing device 9, and a clamping and fixing mechanism 10 provided between the outer wall of the measuring cylinder 8 and the top of the flat plate weighing device 9, and an insertion mechanism 12 provided between the bottom end of the sealing cover plate 6 and the top end of the measuring cylinder 8, and the electric control valve 5, the sliding cylinder 7 and the flat plate weighing device 9 are all electrically connected to the preparation control terminal 2.

[0026] Beneficial effects: During the chemical solution preparation process, the mixing control terminal 2 controls and manages the addition and weighing of raw materials, as well as the fixing and docking of containers, ensuring the orderly preparation of the chemical solution. The electric control valve 5 can be used to control the opening and closing of the feeding pipe 4 to facilitate the feeding of raw materials. At the same time, the slide cylinder 7 can adjust the position of the measuring cylinder 8 to facilitate docking and sealing with the sealing cover plate 6. Furthermore, the flat plate weigher 9 weighs the solid raw materials after they are fed into the measuring cylinder 8 to obtain the corresponding feeding data, which facilitates the control of subsequent additions.

[0027] like Figure 1-2 As shown, the clamping and fixing mechanism 10 includes a pair of telescopic cylinders 1001. Both telescopic cylinders 1001 are fixedly connected to the top of the flat weighing device 9, and the output ends of both telescopic cylinders 1001 are fixedly connected to clamping plates 1002. The opposite sides of the pair of clamping plates 1002 are in close contact with the outer wall of the measuring cylinder 8. Both telescopic cylinders 1001 are electrically connected to the adjustment control terminal 2. Both clamping plates 1002 are arc-shaped, and the surfaces of both clamping plates 1002 are provided with anti-slip layers.

[0028] Beneficial effect: A pair of telescopic cylinders 1001 drive a pair of clamping plates 1002 to clamp and fix the measuring cylinder 8, so that it remains stable during subsequent addition and mixing.

[0029] like Figure 1 and Figure 4As shown, the shaking mechanism 11 includes a hanger 1101 fixedly connected to the top of the mounting frame 1. An electric telescopic rod 1102 is fixedly connected to the bottom of the hanger 1101, and the electric telescopic rod 1102 is electrically connected to the control terminal 2. A cross plate 1103 is fixedly connected to the top of the electric telescopic rod 1102, and both ends of the cross plate 1103 are slidably connected to the inner wall of the hanger 1101. A pair of spring plates 1104 are fixedly connected between the bottom of the cross plate 1103 and the bottom of the hanger 1101. A pair of movable rods 1106 are fixedly connected to the bottom end, and a pair of round holes are drilled in the inner bottom end of the hanger 1101. The bottom ends of the pair of movable rods 1106 pass through the round holes and are fixedly connected to rubber balls 1105. The outer walls of the pair of rubber balls 1105 are in contact with the outer walls of the pair of feed pipes 4 respectively. Slider blocks 11031 are fixedly connected to both ends of the cross plate 1103 near the hanger 1101. A pair of sliding grooves 11032 are drilled in the inner wall of the hanger 1101, and the sliders 11031 are located inside the sliding grooves 11032 and are slidably connected to them.

[0030] Beneficial effects: The electric telescopic rod 1102 repeatedly extends and retracts, causing a pair of rubber balls 1105 to repeatedly strike the outer wall of a pair of feed tubes 4 with the assistance of a pair of spring plates 1104 and a movable rod 1106. This causes the balls to vibrate, and the vibration causes the solid raw materials remaining on the inner wall of the feed tubes 4 to fall into the measuring cylinder 8. This ensures that the released solid raw materials are completely discharged at one time, preventing the residual solid raw materials from falling along with the unreplenished solid raw materials during subsequent replenishment, which would cause a slight over-weighting. This avoids affecting the subsequent chemical solution preparation volume and ensures the accuracy of preparation control.

[0031] like Figure 1-3 As shown, the insertion mechanism 12 includes a plurality of insertion rods 1201 fixedly connected to the bottom end of the sealing cover plate 6, and a plurality of slots 1202 are chiseled at the top end of the measuring cylinder 8, with the insertion rods 1201 located in the slots 1202.

[0032] Beneficial effects: By inserting the rod 1201 and the slot 1202, the sealing cover 6 and the measuring cylinder 8 are precisely aligned to achieve a sealing effect, preventing raw materials from splashing outwards during the addition process and enhancing the use effect.

[0033] like Figure 1-2 As shown, a sealing plug 301 is fitted on the top of each pair of storage cylinders 3, and the outer wall of the sealing plug 301 is in close contact with the inner wall of the storage cylinder 3.

[0034] Beneficial effects: By setting the sealing plug 301, the storage cylinder 3 can be opened when raw materials need to be added, which facilitates the addition of raw materials. After the raw materials are added, it is sealed to prevent dust and impurities from entering the storage cylinder 3 and contaminating the raw materials. In this solution, the number of storage cylinders 3 is not limited to a pair. The specific number should be selected according to the actual use.

[0035] Working principle: First, liquid and solid raw materials are added to a pair of storage cylinders 3 respectively, and sealed with sealing plugs 301. Then, measuring cylinder 8 is placed on top of the flat weighing device 9. Under the control of the dispensing control terminal 2, a pair of telescopic cylinders 1001 are driven to move a pair of clamping plates 1002 towards each other until they contact the measuring cylinder 8 and clamp it. Next, a pair of sliding cylinders 7 drive the measuring cylinder 8 upward, so that the insertion rod 1201 and the slot 1202 are inserted, and the measuring cylinder 8 is precisely aligned and sealed with the sealing cover plate 6. Then, the electric control valve 5 on one side is operated to open the bottom discharge pipe 4 of the storage cylinder 3 containing solid raw materials, releasing a batch of solid raw materials into the measuring cylinder 8. At the same time, the flat weighing device 9 weighs the entire weight and reduces the overall weight to obtain the added weight of solid raw materials. When it is close to the target amount, the electric control valve 5 is operated to repeatedly open and close, so that the missing amount is slowly replenished. Adding solid raw materials facilitates precise addition. During the solid raw material feeding process, when the electric control valve 5 is closed, the electric telescopic rod 1102 repeatedly extends and retracts, driving the cross plate 1103 to move up and down. This causes a pair of movable rods 1106 and rubber balls 1105 to move up and down with the assistance of spring plates 1104. As the pair of rubber balls 1105 move downwards, they strike the outer walls of the pair of feeding pipes 4, causing them to vibrate. This vibration causes the solid raw materials remaining on the inner walls of the feeding pipes 4 to fall into the measuring cylinder 8, ensuring that the released solid raw materials are completely fed out at once. This prevents residual solid raw materials from falling with the missing solid raw materials during subsequent replenishment, which could cause a slight over-weighting and affect the subsequent chemical solution preparation. This ensures the accuracy of the preparation control. After the solid raw materials are added, the electric control valve 5 on the other side is opened, allowing the liquid raw materials to be precisely adjusted under the measurement of the measuring cylinder 8, thereby achieving precise preparation of the chemical solution.

[0036] The wiring diagrams for the dispatch control terminal 2, electric control valve 5, slide cylinder 7, plate weigher 9, telescopic cylinder 1001, and electric telescopic rod 1102 in this solution are common knowledge in the field. Their working principles are well-known technologies, and the appropriate models are selected according to actual use. Therefore, the control methods and wiring layouts for the dispatch control terminal 2, electric control valve 5, slide cylinder 7, plate weigher 9, telescopic cylinder 1001, and electric telescopic rod 1102 will not be explained in detail.
