Abstract
Description
Technical Field
[0001] This utility model relates to chemical equipment, specifically a chemical safety feeding device. Background Technology
[0002] In chemical production, a large amount of powdered materials are used. These powdered materials are usually stored in woven bags. When adding powdered materials to equipment, they are manually lifted to the equipment inlet or hoisted to the equipment inlet. Then, the woven bags are cut open with a blade to let the powdered materials fall into the equipment inlet. As the powdered materials fall, a large amount of dust is scattered out, polluting the surrounding environment and easily inhaled by people nearby, posing a certain safety hazard to personal safety. Utility Model Content
[0003] The purpose of this invention is to address the shortcomings of existing technologies by providing a chemical safety feeding device that can safely feed powdered materials into the equipment, preventing the powdered materials from scattering into the air and affecting the health of personnel.
[0004] The technical solution of this utility model is: a chemical safety feeding device, including a frame, a hopper in the middle of the frame, a grate inside the hopper, a hopper door at the top of the hopper, and a discharge port at the bottom of the hopper, the discharge port being connected to a flange joint through a flexible pipe;
[0005] The outer periphery of the hopper is provided with a set of support plates, and each support plate is provided with a support spring between the bottom and the top of the frame. The outer periphery of the hopper is also provided with a set of vibrators.
[0006] Preferably, the frame includes a rectangular frame, and a set of legs is provided at the bottom of the rectangular frame.
[0007] Preferably, the bottom of the support plate and the top of the frame are provided with a set of limiting posts that extend into the inner hole of the support spring.
[0008] Preferably, the upper end of the silo has a rectangular box structure, and the lower end of the silo has a funnel-shaped structure.
[0009] Preferably, the hopper and the hopper door are connected by hinges, and a hydraulic strut for assisting in opening the hopper door is also connected between the hopper and the hopper door.
[0010] Preferably, the flexible tube is a canvas tube or a plastic corrugated tube.
[0011] Preferably, the hopper is provided with a hook above the grate.
[0012] Compared with the prior art, this utility model has the following advantages:
[0013] This invention enables the safe delivery of powdered materials into chemical equipment, preventing the powdered materials from scattering into the air and affecting the health of surrounding personnel. The use of a vibrator to drive the hopper to vibrate can also accelerate the feeding speed and improve the feeding efficiency.
[0014] This invention uses a flexible tube to connect to the chemical equipment, avoiding the transmission of vibration from the vibrator to the chemical equipment, making the design more reasonable and reliable.
[0015] By connecting a hydraulic strut between the hopper and the hopper door, the hopper door can be opened with the assistance of the hydraulic strut, making it more labor-saving and convenient. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1
[0020] like Figure 1 and Figure 2 A chemical safety feeding device includes a frame 4, which includes a rectangular frame 14, and a set of support legs 15 at the bottom of the rectangular frame 14.
[0021] A hopper 3 is placed in the inner hole in the middle of frame 4.
[0022] The hopper 3 is equipped with a grate 10, and a hopper door 1 is installed on the top of the hopper 3. The upper end of the hopper 3 has a rectangular box structure 11, and the lower end of the hopper 3 has a funnel-shaped structure 12. A discharge port is provided at the bottom of the hopper 3. The discharge port is connected to a flange joint 6 through a flexible pipe 5. The flexible pipe 5 is generally made of canvas or plastic corrugated pipe.
[0023] A set of support plates 8 are provided on the outer periphery of the hopper 3, and a support spring 7 is provided between the bottom of each support plate 8 and the top of the frame 4. The hopper 3 is suspended in the air by a set of support springs 7.
[0024] A set of limiting posts 13 extending into the inner hole of the support spring 7 are provided at the bottom of the support plate 8 and the top of the frame 4, and a set of vibrators 9 are also provided on the outer periphery of the hopper 3.
[0025] Working principle: When in use, frame 4 is installed on top of the chemical equipment, and flange joint 6 is connected to the feed inlet of the chemical equipment;
[0026] Then, the powder material, along with the outer woven bag, is placed into the hopper 3 and supported by the grate 10. The opening of the woven bag is then opened or the woven bag is cut open with a utility knife. The hopper door 1 is then closed, and the vibrator 9 is started. Under the action of the vibrator 9, the hopper 3 vibrates, thereby quickly shaking the powder material through the flexible tube 5 into the chemical equipment. The closed environment formed by the hopper 3 effectively prevents dust from scattering.
[0027] This device is connected to the chemical equipment via a flexible tube 5, which prevents the vibrator 9 from transmitting vibration to the chemical equipment, making the design more reasonable and reliable.
[0028] This device allows for the safe delivery of powdered materials into chemical equipment, preventing the powdered materials from scattering into the air and affecting the health of surrounding personnel. The vibrator 9 drives the hopper 3 to vibrate, which can also accelerate the feeding speed and improve the feeding efficiency. Example 2
[0029] This embodiment is a further optimization based on the above embodiment, specifically:
[0030] like Figure 1 and Figure 2 The hopper 3 and the hopper door 1 are connected by hinges. A hydraulic strut 2 is connected between the hopper 3 and the hopper door 1. The hydraulic strut 2 is used to assist in opening the hopper door 1, which is more labor-saving and convenient.
[0031] A hook is installed inside the hopper 3 above the grate 10. The hook holds the woven bag, effectively preventing the woven bag from falling below the grate 10 during the vibration feeding process.
[0032] This utility model is not limited to the above-described embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this utility model, and the changed content still falls within the protection scope of this utility model.
