Abstract
Description
Technical Field
[0001] This utility model relates to a feeding mechanism, which is in the field of chemical equipment, and specifically to a feeding mechanism for chemical raw materials. Background Technology
[0002] Chemical industry, or chemical industry, is an industrial sector that uses chemical reactions to change the structure, composition, and form of substances to produce chemical products. It is also the foundation for the development of many advanced sciences and provides raw materials for the development of various fields.
[0003] In current chemical production, materials are usually fed manually and require some mixing. However, most chemical materials are highly toxic. The feeding and mixing of powdered materials can easily generate highly toxic dust, while liquid materials can easily generate toxic gases, resulting in significant safety hazards during the production process. This is also why people working in chemical jobs often suffer from occupational diseases.
[0004] To address this, those skilled in the art propose a feeding mechanism for chemical raw materials to minimize the hazards to workers caused by dust generated during the feeding of powdered materials or by the generation of toxic gases from liquid materials. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a feeding mechanism for chemical raw materials. Powdered or small granular materials are directly poured onto the feeding sloping plate, and the feeding is carried out by vibrating the feeding sloping plate through a vibration generator. A grid plate is set to avoid generating toxic dust during vibration feeding. In addition, a suction pump is set to form an inward airflow to prevent dust or toxic gases generated by stirring materials in the feeding hopper from affecting external operators.
[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a chemical raw material feeding mechanism, including a feeding hopper and a stirring rod disposed inside the feeding hopper, wherein the chemical material is manually poured into the feeding hopper and stirred and mixed by the stirring rod before use.
[0007] However, the existing open-type feed hopper will generate airflow due to the closed structure when pouring materials. This airflow can easily carry toxic dust or evaporated gas back into the operator and affect them. In response, those skilled in the art have proposed improvements to the existing feed hopper to minimize the impact of toxic dust or vapor on the operator.
[0008] The top inner wall of the feed hopper is provided with a feed ramp, on which powder or small granular solid materials are poured. The feed is controlled by the inclination angle of the feed ramp.
[0009] A grid plate is fixed on the upper surface of the feed sloping plate. The material can contact the feed sloping plate below through the grid plate, and the grid plate can also prevent dust from being generated when the powder material is fed.
[0010] A suction pump is connected to the top of the feed hopper. The suction pump forms an airflow into the feed hopper to prevent toxic dust or gas from spreading outward and directly affecting the operators.
[0011] Preferably, the inner wall of the feed hopper is fixedly connected to an installation plate, and a rubber pad is provided on the inner wall of the feed hopper and on the installation plate. The feed ramp is pressed against the inner wall of the feed hopper by the installation plate and the rubber pad. The installation plate and the rubber pad can ensure a certain degree of mobility of the feed ramp in the feed hopper, and can also prevent toxic dust from leaking out of the gaps.
[0012] Preferably, a fixing rod is fixedly connected to the inner wall of the feed hopper corresponding to the bottom of the feed ramp. A vibration generator is provided between the fixing rod and the feed ramp. The vibration generator drives the feed ramp to vibrate at a certain frequency to help the material slide along the feed ramp for feeding.
[0013] The side wall of the feed hopper is fitted with an insert plate corresponding to the bottom of the feed ramp. The feed ratio of materials on multiple feed ramps can be controlled by the insert plate.
[0014] Preferably, a wind hood is fixedly connected to the lower surface of the feed chute. The wind hood helps to form a certain degree of airflow at the bottom of the feed chute, preventing dust and gas in the feed hopper from escaping through the feed hopper and affecting the operator.
[0015] A gate is installed on the side of the hood corresponding to the insert plate. When some of the feed ramps are not in use, the air inlet of the hood at that location is also closed, reducing the power loss of the suction pump and ensuring the strength of the airflow at other locations.
[0016] Preferably, a positioning block is fixedly connected to the upper surface of the feeding inclined plate, and a locking wedge is fixedly connected to the side of the positioning block. The grid plate is suspended above the feeding inclined plate through the positioning block and the locking wedge on its side, ensuring a certain distance between the grid plate and the upper surface of the feeding inclined plate for material sliding feeding.
[0017] Preferably, a suction pipe is fixedly connected to the side wall of the feed hopper and the lower surface near the feed inclined plate. A dust collector bag is provided inside the suction pipe. The suction pump is connected to the feed hopper through the suction pipe. The suction pump sucks out dust materials from the air and filters them through the dust collector bag.
[0018] This utility model discloses a feeding mechanism for chemical raw materials, which has the following beneficial effects:
[0019] 1. The feeding mechanism of this chemical raw material is different from the open-type feeding hopper of the existing technology. When feeding manually or stirring, the airflow collision caused by the side wall will generate toxic dust. This equipment reduces the feeding drop by reducing the feeding drop, which can reduce the generation of dust. In addition, the mesh plate and vibration generator help the material slide along the feeding hopper. Combined with other control structures, it helps to mix multiple materials. Finally, the suction pump set on the side of the feeding hopper forms an airflow to the inside of the feeding hopper, which prevents toxic air from escaping from the feeding hopper and affecting the operators.
[0020] 2. The feeding mechanism of this chemical raw material has a wind hood installed on the lower surface of the feeding inclined plate. This not only facilitates the control of airflow according to the use of the feeding inclined plate and ensures the utilization rate of the suction pump, but also amplifies the airflow generated by the suction pump, avoiding the problem of poor airflow effect caused by overall suction.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] This utility model discloses a feeding mechanism for chemical raw materials;
[0029] According to the appendix Figure 1 and attached Figure 2 As shown, it includes a feed hopper 1 and a stirring rod 2 disposed inside the feed hopper 1. Chemical materials are manually poured into the feed hopper 1 and stirred and mixed by the stirring rod 2 before use.
[0030] However, the existing open-type feed hopper 1 will generate airflow due to the closed structure when dumping materials. This airflow can easily carry toxic dust or evaporated gas backflow into the operator and cause an impact. In response to this, those skilled in the art have proposed improvements to the existing feed hopper 1 to minimize the impact of toxic dust or vapor on the operator.
[0031] The top inner wall of the feed hopper 1 is provided with a feed ramp 3, on which powder or small granular solid materials are poured. The feed is controlled by the inclination angle of the feed ramp 3.
[0032] A grid plate 4 is fixed on the upper surface of the feed ramp 3. The material can contact the feed ramp 3 below through the grid plate 4, and the grid plate 4 can also prevent dust from being generated when the powder material is fed.
[0033] A suction pump 5 is connected to the top of the feed hopper 1. The suction pump 5 forms an airflow into the feed hopper 1 to prevent toxic dust or gas from spreading outward and directly affecting the operators.
[0034] According to the appendix Figure 2 As shown, an installation plate 6 is fixedly connected to the inner wall of the feed hopper 1. A rubber pad 7 is provided on the inner wall of the feed hopper 1 and on the installation plate 6. The feed inclined plate 3 is pressed against the inner wall of the feed hopper 1 by the installation plate 6 and the rubber pad 7. The installation plate 6 and the rubber pad 7 can ensure a certain degree of mobility of the feed inclined plate 3 in the feed hopper 1, and can also prevent toxic dust leakage from gaps.
[0035] Preferably, a fixing rod 8 is fixedly connected to the inner wall of the feed hopper 1 corresponding to the bottom of the feed inclined plate 3. A vibration generator 9 is provided between the fixing rod 8 and the feed inclined plate 3. The vibration generator 9 drives the feed inclined plate 3 to vibrate at a certain frequency to help the material slide along the feed inclined plate 3 for feeding.
[0036] According to the appendix Figure 3 and attached Figure 4 As shown, the side wall of the feed hopper 1 is provided with a plate 10 inserted into the bottom of the feed ramp 3. The feeding ratio of materials on multiple feed ramps 3 can be controlled by the plate 10.
[0037] Preferably, a fan hood 11 is fixedly connected to the lower surface of the feed chute 3. The fan hood 11 helps to form a certain degree of airflow at the bottom of the feed chute 3, so as to prevent dust and gas in the feed hopper 1 from escaping through the feed hopper 1 and affecting the operator.
[0038] A gate 12 is installed on the side of the hood 11 corresponding to the insert plate 10. When some feed ramps 3 are not in use, the air inlet of the hood 11 at that location is also closed, reducing the power loss of the suction pump 5 and ensuring the strength of the airflow at other locations.
[0039] Preferably, a positioning block 13 is fixedly connected to the upper surface of the feeding inclined plate 3, and a locking wedge 14 is fixedly connected to the side of the positioning block 13. The grid plate 4 is suspended above the feeding inclined plate 3 through the positioning block 13 and the locking wedge 14 on its side, ensuring a certain distance between the grid plate 4 and the upper surface of the feeding inclined plate 3 for material sliding feeding.
[0040] According to the appendix Figure 1 As shown, a suction pipe 15 is fixedly connected to the side wall of the feed hopper 1 and the lower surface near the feed inclined plate 3. A dust collector bag 16 is provided inside the suction pipe 15. The suction pump 5 is connected to the feed hopper 1 through the suction pipe 15. The suction pump 5 sucks out the dust material in the air and filters it through the dust collector bag 16.
[0041] The feeding mechanism of this chemical raw material differs from the open-type feeding hopper 1 of the existing technology. When feeding manually or mixing, the airflow collision caused by the side wall will generate toxic dust. This equipment reduces the feeding drop by using the feeding ramp 3, which can reduce the generation of dust. In addition, the grid plate 4 and the vibration generator 9 help the material slide along the feeding ramp 3 for feeding. Combined with other control structures, it helps to mix multiple materials. Finally, the suction pump 5 set on the side of the feeding hopper 1 forms an airflow to the inside of the feeding hopper 1, which prevents toxic air from escaping from the feeding hopper 1 and affecting the operators.
[0042] Furthermore, a wind hood 11 is provided on the lower surface of the feed inclined plate 3, which not only facilitates the control of airflow according to the use of the feed inclined plate 3 and ensures the utilization rate of the suction pump 5, but also amplifies the airflow generated by the suction pump 5, avoiding the problem of poor airflow effect caused by overall suction.
[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
