Description

Technical Field

[0001] The utility model relates to the technical field of material feeding, in particular to a material quantitative feeding device for chemical additive production. Background Art

[0002] The constant feeder is a device integrating material transportation, weighing and metering, and constant feeding, and has important and extensive applications in modern production batching. The constant feeder can continuously feed and meter bulk materials, various blocky and granular materials (such as limestone, iron powder, clay) and powdery materials (such as fly ash, cement), etc. The metering accuracy is generally ≤±1% (under the same environment, the metering accuracy of the screw constant feeder is lower than that of the belt constant feeder). In addition, the constant feeder can also be configured with a software system, including an instrument and a host computer software system, to provide technical and data support for production control, production scheduling, and production management in various industrial fields. If manual weighing is used, production needs to be interrupted, and the weighing error by manual is larger, and even there will be human cheating behaviors, which also increases the management difficulty. The constant feeder avoids the above problems, reduces the original labor cost for weighing, and provides accurate data basis for production management, control, and scheduling. That is to say, the constant feeder has a high degree of automation and informatization, which helps to improve production efficiency, reduce production costs, and strengthen production management.

[0003] The publication number is CN216835310U, a chemical material feeding device. The utility model discloses a chemical material feeding device, belonging to the technical field of chemical production, including a storage tank. The center of the top of the storage tank is fixedly connected with a concave frame. The inner cavity of the concave frame is slidably connected with a limiting plate. The center of the top of the inner cavity of the storage tank is rotatably connected with a sleeve through a bearing. The inner surface of the sleeve is threadedly connected with a screw rod. When in use, when feeding is required, the servo motor plug is powered on, and the external controller of the servo motor is started, so that the output end of the servo motor drives the driving gear to rotate. The driving gear drives the driven gear to rotate. The driven gear drives the sleeve to threadedly rotate on the outer surface of the screw rod, so that the screw rod drives the conical sealing plate and the sealing ring to move out of the inner cavity of the groove, and the material moves out of the inner cavity of the storage tank through the groove and the discharge pipe. The device is simple to operate and convenient to use, thus avoiding the phenomenon of blockage at the feeding port and affecting the reaction in the reaction kettle.

[0004] However, it is found that the following problems exist in the implementation of the related technology. This device cannot quantitatively feed chemical materials according to requirements and cannot provide accurate data basis for production management, control, and scheduling.

[0025] Embodiment 1

[0026] As Figures 1 to 4 shown, this embodiment proposes a material quantitative feeding device for chemical additive production, including a storage tank 4. It is characterized in that a conveying mechanism 3 is arranged on the upper side of the storage tank 4, and a top plate 5 is arranged between the storage tank 4 and the conveying mechanism 3. A quantitative feeding mechanism 2 is arranged on the lower side of the storage tank 4, and a valve mechanism is arranged between the quantitative feeding mechanism 2 and the storage tank 4. A level sensor is installed inside the storage tank 4. The conveying mechanism 3 includes a conveying mechanism housing 302. A second threaded rod 303 is arranged inside the conveying mechanism housing 302. A second motor 306 is arranged at the upper end of the top plate 5, and a shaft rod 305 is fixedly connected to one end of the second threaded rod 303 at the end of the output shaft of the second motor 306. One side upper end of the conveying mechanism housing 302 is fixedly connected with a feed inlet 301, and the other side lower end is fixedly connected with a discharge outlet 304. A groove is formed on the top plate 5, and the discharge outlet 304 is arranged in the groove. The second threaded rod 303 forms a rotating structure inside the conveying mechanism housing 302 through the shaft rod 305 and the second motor 306. The level sensor can detect the capacity of the chemical additive inside the storage tank 4. Pour the chemical additive into the inside of the conveying mechanism 3 from the feed inlet 301, and start the second motor 306 to drive the second threaded rod 303 to rotate inside the conveying mechanism housing 302 through the shaft rod 305, thereby pushing the internal chemical additive to move to the discharge outlet 304 and enter the lower storage tank 4.

[0027] Further, the valve mechanism 1 includes a valve housing 103. The top of the valve housing 103 is fixedly connected to the storage tank 4 through a first conveying pipe 101. A rectangular groove is provided inside the valve housing 103, and a baffle plate 102 is arranged inside the valve housing 103 through the rectangular groove. A first threaded rod 104 passes through the baffle plate 102, and one end of the first threaded rod 104 penetrates the valve housing 103 and is fixedly connected to an external valve handle 105. The baffle plate 102 forms a sliding structure inside the valve housing 103 through the first threaded rod 104. The quantitative feeding mechanism 2 includes a feeding device housing 201. A rotating rod 202 is penetrated inside the feeding device housing 201 through a bearing. Four baffle plates 206 are fixedly connected to the outer wall of the rotating rod 202. The four baffle plates 206 are annularly arranged on the rotating rod 202. The four baffle plates 206 are arranged inside the feeding device housing 201. The four baffle plates 206 form a rotating structure inside the feeding device housing 201 through the rotating rod 202. One end of the feeding device housing 201 is fixedly connected to a fixing plate 204. A first motor 203 is arranged above the fixing plate 204, and the end of the output shaft of the first motor 203 is fixedly connected to one end of the rotating rod 202. The top of the feeding device housing 201 is fixedly connected to the valve mechanism 1 by a third conveying pipe 6. The bottom of the quantitative feeding mechanism 2 is fixedly connected to a second conveying pipe 205. Rotating the valve handle 105 pushes the baffle plate 102 inside the valve mechanism 1 to slide through the thread on the first threaded rod 104, thereby controlling the opening and closing of the valve mechanism 1, and realizing the storage or outflow of the chemical additives inside the storage tank 4. Starting the first motor 203 drives the rotating rod 202 and the baffle plates 206 to rotate uniformly inside the feeding device housing 201. Through the gap between the two baffle plates 206 and the uniform rotation of the rotating rod 202 driven by the first motor 203, quantitative feeding is realized.

[0028] The working principle and usage process of the present utility model: Pour the chemical additives from the feed port 301 into the conveying mechanism 3. Start the second motor 306 to drive the second threaded rod 303 to rotate inside the conveying mechanism housing 302 through the shaft rod 305, thereby pushing the chemical additives inside to move and send them to the discharge port 304 and into the lower storage tank 4. The level sensor can detect the capacity of the chemical additives inside the storage tank 4. When the chemical additives inside are full, rotate the valve handle 105 at the lower end and drive the first threaded rod 104 at the same time. Push the baffle plate 102 inside the valve mechanism 1 to slide through the thread on the first threaded rod 104, thereby controlling the opening and closing of the valve mechanism 1, and realizing the storage or outflow of the chemical additives inside the storage tank 4. Open the valve mechanism 1, and the chemical additives flow into the quantitative feeding mechanism. Start the first motor 203 to drive the rotating rod 202 and the baffle plates 206 to rotate uniformly inside the feeding device housing 201. Through the gap between the two baffle plates 206 and the uniform rotation of the rotating rod 202 driven by the first motor 203, quantitative feeding is realized, and it flows out quantitatively through the second conveying pipe 205 at the lower end.
