Description

Technical Field

[0001] The utility model belongs to the technical field of weighing detection, and in particular relates to weighing detection equipment for the production of high-activity calcium hydroxide. Background Art

[0002] High-activity calcium hydroxide is also called high-specific surface area calcium hydroxide. High-specific surface area calcium hydroxide has the characteristics of being porous, highly active, well dispersed, and highly utilized. Its specific surface area is 2-3 times that of ordinary calcium hydroxide, and is widely used in the flue gas desulfurization industry. During the production of high-activity calcium hydroxide, a specified amount of calcium oxide powder needs to be mixed with an appropriate amount of water to form a slurry for grinding. However, at present, when weighing calcium oxide powder, the calcium oxide powder is poured into a specified container, and the size of the container is used to limit the specified weight of calcium oxide powder. However, this method is not weighed, and errors are prone to occur, resulting in inaccurate proportions.

[0003] Chinese patent application number 202321131973X discloses a calcium hydroxide quantitative detection device, including a base, a material receiving frame is fixedly connected to the upper surface of the base, a placement plate is movably provided on the inner side of the material receiving frame, a plurality of slots are provided on the upper surface of the placement plate, a material box is movably embedded and installed on the inner side of the slot, a lifting component is fixedly connected to the upper surface of the base, a weighing platform is fixedly connected above the lifting component, a protective frame is fixedly embedded and installed on the inner lower surface of the material receiving frame, sliding grooves are provided on both side surfaces of the material receiving frame, and a scraper is provided in the movable chamber inside the material receiving frame.

[0004] The above patent solution can facilitate quantitative weighing of multiple portions of calcium hydroxide raw material powder at the same time, meet the requirements of testing multiple portions of calcium hydroxide raw material powder at the same time, and speed up the quantitative weighing of calcium hydroxide raw materials. However, high-activity calcium hydroxide has high requirements for the accuracy of the specified amount of calcium oxide powder when proportioning. Since the above solution cannot quickly test a single portion of calcium hydroxide raw material, that is, calcium oxide powder, the above solution is still prone to inaccurate proportioning when preparing high-activity calcium hydroxide.

In short, for ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. Example

[0023] like Figure 1-4 As shown, a weighing and testing equipment for the production of highly active calcium hydroxide includes a storage tank 1, a weight detection device and a conveyor belt 2. A discharging device is provided at the bottom of the storage tank 1, and the conveyor belt 2 is located below the discharging device. A plurality of fixed material barrels 3 are provided on the conveyor belt 2. The side of the storage tank 1 is supported by a support column. Calcium oxide powder is stored in the storage tank 1. The storage tank 1 has a cylindrical structure above and a conical structure below. The cylindrical structure above can withstand a large pressure to ensure that the storage tank 1 remains stable when filled with materials. The conical structure below is conducive to the natural flow of materials to the outlet under the action of gravity, reducing the residual materials in the tank. The calcium oxide powder is discharged to the fixed material barrel 3 on the conveyor belt 2 through the bottom discharging device. Each fixed material barrel 3 is loaded and weighted by the weight detection device after being filled. In this embodiment, the discharging device includes a transverse transmission pipe 13 and a longitudinal discharge pipe 14. A discharge auger 15 is arranged inside the transverse transmission pipe 13. The discharge auger 15 is driven by a corresponding motor to drive the spiral to rotate, so that the calcium oxide powder can be continuously and smoothly transported and discharged into the fixed material barrel 3 through the longitudinal discharge pipe 14.

[0024] Combination Figure 2 and Figure 3The weight detection device includes a longitudinal support frame 4, an electric telescopic rod 5 is connected to the lower side of the top of the longitudinal support frame 4, and a transverse support frame 6 is connected to the lower side of the electric telescopic rod 5. The longitudinal support frame 4 and the transverse support frame 6 are both U-shaped structures and are arranged perpendicular to each other. The opening of the longitudinal support frame 4 faces the ground, and the opening of the transverse support frame 6 faces the forward direction of the fixed material barrel 3. The ends of both ends of the transverse support frame 6 are connected to support blocks 7, and a sliding rod 8 is telescopically provided above each support block 7. A pressure sensor 9 is provided at the inner bottom of the support block 7. The sliding rod 8 extends downward through the support block 7 and is connected to a sliding plate 10. A load-bearing spring 11 is connected to the lower side of the sliding plate 10, and the bottom of the load-bearing spring is connected to the pressure sensor 9. A zigzag bearing plate 12 is provided above the sliding rod 8.

[0025] When the conveyor belt 2 drives the fixed material barrel 3 filled with calcium oxide powder to move, when the outer peripheral protruding edge at the top of the fixed material barrel 3 moves to the top of the zigzag load-bearing plate 12, the conveyor belt 2 stops moving. At this time, the transverse support frame 6 is lifted by the electric telescopic rod 5, and the transverse support frame 6 drives the support blocks 7 and the zigzag load-bearing plate 12 on both sides to lift, thereby lifting the entire fixed material barrel 3. The weight of the fixed material barrel 3 is successively transferred to the pressure sensor 9 by the zigzag load-bearing plate 12, the sliding rod 8, the sliding plate 10 and the load-bearing spring 11. The telescopic design of the sliding rod 8 in the support block 7, and the connection of the sliding plate 10 with the sliding rod 8, form a stable guide system together. This makes it possible for the weight of the fixed material barrel 3 to be steadily and evenly transferred to the sliding plate 10 and the load-bearing spring 11 during the weighing process, avoiding the distortion or deflection caused by uneven force. The use of the load-bearing spring 11 plays a role in buffering and balancing weight. When the weight is transferred to the spring through the sliding plate 10, the spring can be adaptively adjusted according to its own elastic characteristics to ensure that the weight is evenly distributed during the transfer process. At the same time, the buffering effect of the spring can also reduce the weighing error caused by impact or vibration. Since the weight has been evenly distributed and buffered by the previous structure, the pressure sensor 9 can receive a relatively stable and accurate signal, thereby performing accurate measurement.

[0026] Combination Figure 5, a pushing device and a receiving box 16 are provided on both sides of the conveyor belt 2, and the pushing device includes a support rod 17 at the bottom, a pushing motor 18 is provided on the support rod 17, and a pushing plate 19 is provided at the output end of the pushing motor 18. When a fixed material barrel 3 with unqualified weight is detected, the electric telescopic rod 5 is first used to drive the zigzag supporting plate 12 to descend, so that the bottom of the fixed material barrel 3 returns to the conveyor belt 2, and the zigzag supporting plate 12 is no longer in contact with the protruding edge of the outer periphery of the top of the fixed material barrel 3. The conveyor belt 2 drives the fixed material barrel 3 to move to the position of the pushing plate 19, and the pushing motor 18 drives the pushing plate 19 to push the unqualified fixed material barrel 3 on the conveyor belt 2 into the receiving box 16, while the pushing barrel with qualified weight is moved to the designated stacking position to wait for subsequent proportioning.

[0027] Combination Figure 6 , a stirring motor 20 is provided at the top of the storage tank 1, and the output end of the stirring motor 20 extends downward and is connected to a stirring rod 21, and a stirring blade is provided on the side of the stirring rod 21. The stirring rod 21 and the stirring blade connected to the output end of the stirring motor 20 can effectively stir the calcium oxide powder in the tank. This can not only prevent the powder from agglomerating and ensure the uniformity of the powder, but also help to improve the fluidity of the powder, so that it can be discharged more smoothly. The stirring blade includes a first stirring blade 22 located at the top and a second stirring blade 23 located at the bottom, the first stirring blade 22 is vertically arranged, and the second stirring blade 23 is inclined. The vertically arranged first stirring blade 22 can effectively break up the material during the stirring process, especially in the cylindrical structure part above the storage tank 1, which can ensure that the material can be fully stirred at the top. The inclined second stirring blade 23 can better adapt to the characteristics of the conical structure below the storage tank 1, and stir the material more carefully, especially near the outlet, to ensure that the material reaches a uniform state before discharge.
