Description

Technical Field

[0001] This utility model relates to the technical field of material dust suppression equipment, specifically to a feeding device for volatile, irritating odorous materials. Background Technology

[0002] In existing chemical production and material handling processes, the feeding process of volatile materials with irritating odors generally presents problems such as harsh working environment, damage to the health of operators, and high safety risks.

[0003] Taking the feeding operation of ammonium bicarbonate as an example, the current process requires that the ammonium bicarbonate be manually unpacked and poured directly into the dissolving tank. During this process, the feeding port of the dissolving tank is open, causing a large amount of irritating ammonia gas produced by the decomposition of ammonium bicarbonate to volatilize into the work space, resulting in a high ammonia concentration throughout the room.

[0004] Although operators wear protective masks, long-term exposure to high concentrations of ammonia gas can still cause varying degrees of irritation and damage to the respiratory system, skin, and eyes, seriously affecting the physical and mental health of employees.

[0005] In addition, ammonia, as a flammable and explosive gas, poses a potential explosion risk when it accumulates in the air, seriously threatening production safety. Utility Model Content

[0006] In view of this, the present invention provides a feeding device for volatile and irritating odorous materials. The present invention can reduce the dust generated when materials are fed into the processing chamber, thereby not only optimizing the working environment but also reducing the waste of raw materials.

[0007] To solve the above-mentioned technical problems, this utility model provides a feeding device for volatile and irritating odorous materials, including a material processing chamber with a feed inlet. A first dust suction pipe is connected to the processing chamber. One end of the first dust suction pipe is connected to an external exhaust fan, and the other end of the first dust suction pipe is connected to the inside of the processing chamber. The first dust suction pipe can prevent the material entering the processing chamber from floating out of the processing chamber under the action of air pressure. A second dust suction pipe is also provided in the corresponding processing chamber. One end of the second dust suction pipe is located directly above the feed inlet, and the other end of the second dust suction pipe is connected to the external exhaust fan. The second dust suction pipe can suck away the dust near the feed inlet.

[0008] The ends of the first and second dust suction pipes furthest from the processing chamber are connected to the return pipe via a T-junction. The two pipes can work simultaneously through the same exhaust mechanism, which also facilitates the collection of dust materials.

[0009] The second dust extraction pipe is also equipped with a flow guide hood at the end near the processing chamber. The flow guide hood can guide the dust and expand the dust extraction area.

[0010] The feed inlet is equipped with a cutting blade, which is used to cut the material bag, so that the material bag can be put down, saving manual labor.

[0011] The cutting blade is detachably fixed in the middle of the feed inlet.

[0012] A support plate is horizontally connected inside the feed inlet, and a cutting blade is vertically fixed to the support plate by bolts, which facilitates the replacement of the cutting blade.

[0013] Multiple rollers are also rotatably installed inside the feed inlet. The multiple rollers are located on the same horizontal plane, and the cutting surface of the cutter is in the same direction as the rollers. At the same time, the top of the cutter is higher than the highest horizontal line of the rollers, so there is no need to lift the material bag when it is cut or pulled.

[0014] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects: 1. Optimize the working environment and protect personnel health: By setting up a first dust extraction pipe and a second dust extraction pipe, the first dust extraction pipe can prevent materials entering the processing chamber from floating out of the processing chamber under air pressure, while the second dust extraction pipe can suck away dust near the feed inlet, effectively reducing the amount of dust and irritating gas volatilization generated when materials are put into the processing chamber, greatly improving the environmental quality of the working space, reducing the contact between operators and harmful gases and dust, and thus protecting the health of operators.

[0015] 2. Reduce safety risks: It reduces the volatilization of irritating gases and lowers the concentration of gases in the air, thereby effectively reducing the possibility of safety accidents such as explosions and improving the safety of the production process.

[0016] 3. Reduce raw material waste: The ends of the first and second dust suction pipes furthest from the processing chamber are connected to the return pipe via a T-junction. The two pipes can work synchronously through the same exhaust mechanism, which facilitates the collection of dusty raw materials and reuse of the collected dusty raw materials, thereby reducing raw material waste and lowering production costs.

[0017] 4. Improve feeding efficiency and reduce labor intensity: The feed inlet is equipped with a cutting blade that can be used to cut open the material bag. Operators only need to put the material bag down to complete the feeding, saving the labor of manually opening the bag and improving feeding efficiency.

[0018] 5. Enhanced dust collection effect: The second dust collection pipe is equipped with a guide hood at one end near the processing chamber. The guide hood can guide the dust and expand the dust collection area, so that the second dust collection pipe can more effectively suck up the dust near the feed inlet, which enhances the dust collection effect of the entire device and further improves the working environment.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0022] This embodiment provides a feeding device for volatile, irritating odorous materials, such as... Figure 1 As shown: The system includes a material processing bin 1, with a feed inlet 2 at the top. Materials can be fed into the processing bin 1 through the feed inlet 2. The feed bin can be funnel-shaped for easier material feeding. The processing bin 1 also has a first dust extraction pipe 3, one end of which is connected to an external ventilation system, and the other end is connected to the interior of the processing bin 1. The first dust extraction pipe 3 is also connected to the external ventilation system, allowing the ventilation system to draw dust floating in the processing bin 1 into the first dust extraction pipe 3 (dust materials, upon entering the processing bin 1, will be lifted by air pressure and then float outwards through the feed inlet 2). A second dust extraction pipe 4 is also provided, one end of which is located directly above the feed inlet 2, and the other end is connected to the external dust extraction system. The dust extraction system allows dust floating near the feed inlet 2 to be sucked into the second dust extraction pipe 4.

[0023] Preferably, the end of the second dust collection pipe 4 is also provided with a flow guide 6, which is also funnel-shaped, so as to not only expand the dust collection area but also guide the dust.

[0024] Specifically, the ends of the first and second dust suction pipes furthest from the processing chamber 1 are connected to the return pipe 5 via a T-junction. This means that one ventilation device can suction dust from both dust suction pipes through the return pipe 5, and the dust entering the return pipe 5 can be collected uniformly, treated, and reused, thereby reducing raw material consumption.

[0025] Furthermore, a cutting blade 7 is vertically installed inside the feed inlet 2, such as... Figure 1 , 2 As shown in Figure 3: A support plate is horizontally connected inside the feed inlet 2. The two ends of the support plate are connected to the opposite ends of the feed inlet 2. A cutting blade 7 is fixed to the support plate by bolts. When the material bag is placed on the feed inlet 2, the cutting blade 7 can naturally cut the material bag. Pulling the material bag will cause it to be torn, and the material inside the bag can fall into the feed inlet 2 through the gap. Since the cutting blade is fixed by bolts, the cutting blade 7 can also be disassembled by bolts, so that the cutting blade 7 can be maintained or replaced.

[0026] It is worth mentioning that multiple rollers 9 are also rotatably installed inside the feed inlet 2, such as... Figure 3 As shown: Multiple rollers 9 are arranged in a linear array, with the upper surfaces of the multiple rollers 9 located on the same horizontal plane, and the cutting surface of the cutting blade is consistent with the rolling direction of the rollers 9. At the same time, the top of the cutting blade is higher than the highest horizontal line of the rollers 9. That is, when the material bag is placed on the feed port 2, the rollers 9 can provide support for the material bag and reduce resistance during the movement of the material bag, thereby further increasing work efficiency.

[0027] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
