Description

Technical Field

[0001] This utility model relates to the field of chemical safety feeder technology, specifically a chemical safety feeder. Background Technology

[0002] Chemical feeders are key equipment used in chemical production to feed raw materials into reactors and other equipment. Their core function is to achieve safe, accurate, and efficient feeding operations.

[0003] Currently, when feeding chemical raw materials, the raw materials are placed into chemical equipment. However, some chemical reactions produce harmful gases. Because the chemical equipment is often kept running during feeding, these harmful gases will volatilize into the environment, posing a safety hazard to workers who are working in this environment for extended periods. This application proposes a chemical safety feeder that separates the storage hopper and the feeding hopper during the feeding process. This prevents the chemical equipment from being kept running during feeding, thus avoiding the continuous volatilization of harmful gases into the environment and solving the problem of harmful gases posing a hazard to workers. Utility Model Content

[0004] The purpose of this invention is to provide a chemical safety feeder to solve the problems mentioned in the background art.

[0005] A chemical safety feeder includes a feeding shell, a storage hopper mounted on the feeding shell for loading materials, and a discharge hopper mounted below the feeding shell for discharging materials. A feeding unit is disposed within the feeding shell, the feeding unit comprising:

[0006] A feeding cylinder, which is rotatably connected in the feeding housing, is used to separate the storage hopper and the feeding hopper;

[0007] A connecting shaft, which is inserted into the inside of the connecting shaft, and the connecting shaft is rotatably connected to the inner wall of the feeding shell;

[0008] The loading troughs are evenly spaced within the feeding cylinder and are used for loading raw materials.

[0009] Preferably, a stirring rod is rotatably connected to the storage hopper, the stirring rod being used to disperse the raw materials.

[0010] Preferably, a transmission unit is provided between the feeding shell and the storage hopper. The transmission unit includes a first transmission wheel and a second transmission wheel. The first transmission wheel is sleeved on the rotating shaft of the stirring rod, and the second transmission wheel is sleeved on the connecting shaft of the feeding unit.

[0011] Preferably, the outer peripheral walls of the first and second transmission wheels are interference-fitted with transmission belts, which are used to drive the feeding unit and the stirring rod to rotate simultaneously.

[0012] Preferably, a drive motor is installed on the feeding shell, and the output end of the drive motor is installed with the connecting shaft.

[0013] Preferably, a feed inlet is provided on the top of the feeding shell.

[0014] Preferably, a feeding port is provided at the bottom of the feeding shell.

[0015] By adopting the above technical solution, the storage hopper and the feeding hopper are separated during the feeding process, which avoids the chemical equipment from being constantly turned on during the feeding process, causing harmful gases to continuously volatilize into the outside world.

[0016] Compared with the prior art, the beneficial effects of this utility model are: this chemical safety feeder,

[0017] Equipped with a feeding cylinder, connecting shaft, and loading trough, the feeding cylinder is started to rotate during raw material feeding. When the loading trough in the feeding cylinder connects with the storage hopper, the bottom of the feeding cylinder seals the feeding shell, isolating the feeding shell from the feeding hopper. When the feeding cylinder drives the loading trough to rotate, connecting the loading trough with the feeding hopper, and raw materials are fed into the feeding hopper, the feeding cylinder seals the top of the feeding shell, isolating the feeding shell from the storage hopper. This effectively prevents harmful gases from continuously being discharged from the storage hopper into the external environment during the chemical reaction process, reducing the need for hazardous substance treatment and preventing harmful gases from harming workers.

[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a technical solution: a chemical safety feeder, including a feeding shell 1, a storage hopper 2 installed on the feeding shell 1 for loading materials, a feeding hopper 3 installed below the feeding shell 1 for discharging materials, and a feeding unit 6 provided in the feeding shell 1, the feeding unit 6 including:

[0024] Feeding cylinder 61 is rotatably connected in feeding housing 1, and feeding cylinder 61 is used to separate storage hopper 2 and feeding hopper 3;

[0025] A connecting shaft 62 is inserted into the inside of the connecting shaft 62, and the connecting shaft 62 is rotatably connected to the inner wall of the feeding housing 1;

[0026] The loading trough 63 is equally spaced within the feeding cylinder 61 and is used for loading raw materials.

[0027] When feeding raw materials, the feeding cylinder 61 is started to rotate. When the loading trough 63 in the feeding cylinder 61 is connected to the storage hopper 2, the bottom of the feeding cylinder 61 seals the feeding shell 1, isolating the feeding shell 1 from the feeding hopper 3. When the feeding cylinder 61 drives the loading trough 63 to rotate, the loading trough 63 is connected to the feeding hopper 3, and the raw materials are fed into the feeding hopper 3, the feeding cylinder 61 seals the top of the feeding shell 1, isolating the feeding shell 1 from the storage hopper 2. This effectively prevents harmful gases from being continuously discharged from the storage hopper 2 into the external environment during the chemical reaction process, reduces the need for handling harmful substances, and avoids harm to workers from harmful gases.

[0028] A stirring rod 21 is rotatably connected to the storage hopper 2, and the stirring rod 21 is used to break up the raw materials.

[0029] When the transmission unit 5 is started, the stirring rod 21 is rotated while the material is being fed into the feeding unit 6. The rotation of the stirring rod 21 disperses the raw materials, making it easier for them to enter the feeding unit 6 and preventing them from clumping together and affecting the reaction effect.

[0030] A transmission unit 5 is provided between the feeding shell 1 and the storage hopper 2. The transmission unit 5 includes a first transmission wheel 51 and a second transmission wheel 52. The first transmission wheel 51 is sleeved on the rotating shaft of the stirring rod 21, and the second transmission wheel 52 is sleeved on the connecting shaft 62 of the feeding unit 6.

[0031] The outer peripheral walls of the first drive wheel 51 and the second drive wheel 52 are interference-fitted with a drive belt 53, which is used to drive the feeding unit 6 and the stirring rod 21 to rotate simultaneously.

[0032] When feeding materials, the connecting shaft 62 rotates, driving the feeding cylinder 61 to rotate. The feeding cylinder 61 rotates, and the materials are fed. At the same time, the connecting shaft 62 rotates, driving the second transmission wheel 52 to rotate. With the cooperation of the transmission belt 53, the first transmission wheel 51 rotates, driving the stirring rod 21 to rotate.

[0033] A drive motor 4 is installed on the feeding housing 1, and the output end of the drive motor 4 is installed on the connecting shaft 62.

[0034] When it is necessary to control the rotation of the feeding unit 6 for feeding, the drive motor 4 is started to drive the connecting shaft 62 to rotate. Under the rotation of the connecting shaft 62, the feeding cylinder 61 rotates accordingly. When the feeding cylinder 61 rotates and the loading trough 63 is connected to the storage hopper 2, the raw material in the storage hopper 2 enters the loading trough 63 under the action of gravity. At this time, as the feeding cylinder 61 rotates, the loading trough 63 in the feeding cylinder 61 is connected to the feeding hopper 3. At this time, the raw material in the loading trough 63 enters the feeding hopper 3 and enters the chemical equipment through the feeding hopper 3, thus completing the feeding.

[0035] The upper part of the feeding shell 1 is provided with a feeding port 11. When the feeding cylinder 61 rotates, so that the loading groove 63 on the feeding cylinder 61 coincides with the feeding port 11, the raw material in the storage hopper 2 is loaded into the loading groove 63 for feeding.

[0036] A feeding port 12 is provided at the bottom of the feeding shell 1. When the feeding cylinder 61 rotates, the feeding groove 63 on the feeding cylinder 61 coincides with the feeding port 12. At this time, the raw material in the feeding groove 63 is fed into the feeding hopper 3. Under the action of gravity, it enters the chemical equipment through the feeding hopper 3 to complete the feeding.

[0037] When the loading trough 63 coincides with the inlet 11, loading is carried out. At this time, the feeding cylinder 61 seals the inlet 12 to prevent harmful gases in the chemical equipment from entering the storage hopper 2 through the feeding shell 1, and to discharge the harmful gases to the outside environment.
