Description

Technical Field

[0001] The utility model belongs to the field of chemical production technology devices, and specifically relates to a dust-free feeding device. Background Art

[0002] Reactors are widely used in the fields of petroleum, chemical industry, rubber, pesticides, dyes, etc. They can be used to complete processes such as vulcanization, hydrocarbonization, polymerization, condensation, etc., so that the substances participating in the reaction are fully mixed. At present, the reactors used by chemical companies generally feed directly from the manhole of the reactor. This method has the following problems: first, dust fluttering causes the risk of inhalation or skin allergies for operators; second, direct feeding without nitrogen protection poses a safety risk; third, there is a risk of high moisture content during the water-free feeding process. In view of these shortcomings, the present invention has been improved. Summary of the invention

[0003] The utility model aims to provide a dust-free feeding device in view of the deficiencies of the prior art.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a dust-free feeding device, including a feeding bin, on which a pressure gauge is provided, characterized in that: a glove box is provided on the feeding bin, a quick-card feeding port is provided on one side of the glove box, and a pneumatic butterfly valve for filling nitrogen is provided on the other side, an explosion-proof dust removal fan is provided on the top of the glove box, a vibrator is provided on the outer side wall of the lower part of the feeding bin, and a discharge valve is provided at the bottom of the feeding bin.

[0005] The door frame of the quick card feeding port is welded with rectangular tubes around it and is provided with grooves for placing rubber strips, which are used to close the feeding port to form a sealed space after the feeding is completed.

[0006] A grate and a sealing pad made of silicone material are provided at the connection between the feeding bin and the glove box.

[0007] The feeding bin and the glove box are both made of 304 stainless steel, the wall thickness of the feeding bin is 5 mm, and the wall thickness of the glove box is 3 mm.

[0008] The beneficial effects of the utility model are as follows: a closed feeding system consisting of a feeding bin and a glove box is designed. During the feeding process, negative pressure dust is formed inside the glove box and it is not suitable to fall outside. Micro-positive pressure nitrogen is added during the transportation process to ensure low oxygen content during material transportation, which is safer. The contact between materials and operators is reduced, thereby reducing occupational hazards. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] Figure 1 It is a schematic diagram of the utility model;

[0010] In the figure: 1-feeding bin, 2-glove box, 3-quick card feeding port, 4-pneumatic butterfly valve, 5-explosion-proof dust removal fan, 6-vibrator, 7-pressure gauge, 8-discharging valve. DETAILED DESCRIPTION

[0011] like Figure 1 A dust-free feeding device comprises a feeding bin 1, on which a pressure gauge 7 is provided, and is characterized in that: a glove box 2 is provided on the feeding bin 1, a quick-card feeding port 3 is provided on one side of the glove box 2, and a pneumatic butterfly valve 4 for filling nitrogen is provided on the other side, an explosion-proof dust removal fan 5 is provided on the top of the glove box 2, a vibrator 6 is provided on the outer side wall of the lower part of the feeding bin 1, and a discharge valve 8 is provided at the bottom of the feeding bin 1.

[0012] A rectangular tube is welded around the door frame of the quick card feeding port 3 and is provided with a groove for placing the rubber strip.

[0013] A grate and a sealing gasket made of silicone material are provided at the connection between the feeding bin 1 and the glove box 2 .

[0014] The material of the feeding bin 1 and the glove box 2 are both 304 stainless steel, the wall thickness of the feeding bin 1 is 5 mm, and the wall thickness of the glove box 2 is 3 mm.

[0015] Working process: after checking that the status of each valve is normal, open the explosion-proof dust removal fan 5 to prepare for feeding, and feed the material into the feeding bin 1 from the quick-card feeding port 3 of the glove box 2 as needed. During the feeding process, the flying dust is collected on the filter cloth of the explosion-proof dust removal fan 5, and the fan exhaust duct is connected to the workshop exhaust gas emission system; after the feeding is completed, close the quick-card feeding port 3, open the pneumatic butterfly valve 4, form a slight positive pressure of nitrogen in the glove box 2, and then open the discharge valve 8, start feeding into the reactor in a nitrogen environment, and after the feeding is completed, turn on the oscillator 6 to clean the material remaining on the inner wall of the feeding bin 1 into the reactor.
