Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, and specifically relates to a feeding structure suitable for solid particles. Background Technology

[0002] In chemical production or experiments, feeding materials into reactors is a frequent operation. However, some raw materials may spontaneously combust upon contact with air, affecting operational safety; some raw materials are toxic and may cause harm to humans upon skin contact; some materials may also deteriorate upon contact with air, thus affecting subsequent experiments or production; during the feeding process, common feeding structures may introduce external air into the reactor, altering the gas composition inside and affecting subsequent production safety or quality; in addition, feeding structures with variable diameters are prone to clogging when dealing with certain materials.

[0003] Currently available feeding structures are not specifically optimized for this type of raw material. The most common flange-type feeding structure consists of a feeding pipe and a flange blind plate. One end of the feeding pipe is connected to the flange with bolts or other fasteners, while the other end is directly connected to the reactor or storage tank. When not in use, the flange blind plate is installed to isolate it from the outside environment. When feeding is needed, the blind plate is removed, and the material is then added to the feeding pipe through the flange. Under the influence of gravity, the material automatically flows into the reactor, completing the feeding process. Although this structure is simple in form, it cannot be applied to the feeding environment of the special raw materials mentioned above, namely: avoiding skin contact, avoiding air contact, not altering the atmosphere inside the reactor, and preventing clogging during feeding.

[0004] Currently, there are no specially optimized feeding structures on the market for feeding flammable, explosive, and toxic solid materials that spontaneously combust upon contact with air and are toxic upon skin contact. Basic feeding ports cannot guarantee isolation from the outside environment, ease of feeding, or smooth feeding.

[0005] Traditional raw material feeding structures include flange openings, funnels, and other conventional designs. These structures cannot guarantee airtightness during the feeding process. Traditional raw material feeding structures have variable diameter designs, which may cause blockage of the feed inlet when lumpy solid particles are fed in. Traditional feeding structures also cannot replace materials, which may lead to product contamination under certain circumstances.

[0006] Therefore, in order to solve the safety issues in the feeding process and the problem of inlet blockage, it is necessary to improve the feeding structure. Summary of the Invention

[0007] The purpose of this invention is to address the shortcomings of the existing technology by providing a feeding structure suitable for solid particles, ensuring smooth and safe feeding.

[0008] To solve the above technical problems, the technical solution adopted by this utility model is as follows: A feeding structure suitable for solid particles includes a nitrogen purging box and a feeding funnel arranged at the lower end of the nitrogen purging box. The top of the feeding funnel extends into the nitrogen purging box and is equipped with a feeding port blind plate, a blind plate exhaust pipe and an exhaust ball valve installed on the blind plate exhaust pipe. The feeding port blind plate and the feeding funnel are detachably connected, and the feeding funnel extends to the outside of the nitrogen purging box and the two are sealed and fixed at the joint. The feeding funnel is a non-variable diameter structure and includes a first pipe section and a second pipe section, which are connected by a feeding ball valve. The first pipe section is also connected to a nitrogen purging pipe. The first pipe section is a straight pipe section laid at an angle of 3 to 5 degrees to the vertical direction. The second pipe section includes a straight pipe section and an inclined pipe section. The straight pipe section has the same inclination as the first pipe section, while the inclined pipe section has an angle of 6 to 10 degrees to the vertical section.

[0009] The nitrogen purging pipe is also equipped with a purging valve.

[0010] The straight section of the first pipe segment forms a 3.5° angle with the vertical direction.

[0011] The inclined section of the second pipe segment forms a 7.5° angle with the vertical section.

[0012] The side of the nitrogen purging box also has an isolation glove interface for receiving isolation gloves.

[0013] The feeding ball valve is set to the same diameter as the straight pipe section.

[0014] The end of the feeding funnel is connected to the reaction vessel.

[0015] The beneficial effects of this utility model are: (1) The feeding structure applicable to solid particles is provided by setting up a nitrogen purging box and a feeding funnel arranged at the lower end of the nitrogen purging box. The top of the feeding funnel extends into the nitrogen purging box and is equipped with a feeding port blind plate, a blind plate exhaust pipe and an exhaust ball valve installed on the blind plate exhaust pipe. The feeding port blind plate and the feeding funnel are detachably connected, and the feeding funnel extends to the outside of the nitrogen purging box and the two are sealed and fixed at the joint. The feeding funnel is a non-variable diameter structure and includes a first pipe section and a second pipe section. The two are connected by the provided feeding ball valve, and a nitrogen purging pipe is also connected to the first pipe section. The first pipe section is set as a straight pipe section arranged at an angle of 3~5° with the vertical direction, while the second pipe section includes a straight pipe section and an inclined pipe section. The straight pipe section has the same inclination as the first pipe section, while the inclined pipe section has an angle of 6~10° with the vertical section. This can solve the safety problem of the feeding process and also solve the problem of the inlet blockage, ensuring the smooth and safe feeding.

[0016] (2) It can isolate air and use a special atmosphere to purge the feeding environment; while the configuration of the first nitrogen purge pipe and the second nitrogen purge pipe can change the atmosphere to make it consistent with the atmosphere inside the reactor, thus avoiding contamination of the atmosphere inside the reactor.

[0017] (3) The raw materials can be replaced individually in the nitrogen purging box to further ensure the safety and reliability of feeding.

[0018] (4) Personnel and raw materials are completely isolated during the operation to ensure operational safety. Attached Figure Description

[0022] A feeding structure suitable for solid particles includes a nitrogen purging box 1 and a feeding funnel 2 arranged at the lower end of the nitrogen purging box 1. The top end of the feeding funnel 2 extends into the nitrogen purging box 1 and is equipped with a feeding port blind plate 3, a blind plate exhaust pipe 31, and an exhaust ball valve 32 installed on the blind plate exhaust pipe 31. The feeding port blind plate 3 and the feeding funnel 2 are detachably connected, and the feeding funnel 2 extends to the outside of the nitrogen purging box 1 and the two are sealed and fixed at the joint. The feeding funnel 2 is a non-variable diameter structure and includes a first pipe section 4 and a second pipe section, which are connected by a feeding ball valve 5. The first pipe section 4 is also connected to a first nitrogen purging pipe 8. The first pipe section 4 is a straight pipe section arranged at an angle of 3 to 5 degrees to the vertical direction. The second pipe section includes a straight pipe section 61 and an inclined pipe section 62. The straight pipe section 61 has the same inclination as the first pipe section 4, while the inclined pipe section 62 has an angle of 6 to 10 degrees to the vertical section.

[0023] During installation, to accommodate a sufficient amount of raw materials, the feeding ball valve 5 is a large-size ball valve with the same diameter as the straight pipe section. The ball valve has a large diameter and low resistance, which can isolate the feeding funnel from the reactor connected to it, while ensuring a large diameter to avoid blockage during feeding. The first nitrogen purge pipe 8 is connected to the top of the first pipe section 4 to purge any impurities that may remain in the funnel. In order to control the purging, the first nitrogen purge pipe 8 is also equipped with a purge valve 9.

[0024] The exhaust ball valve 32 installed on the exhaust pipe 31 at the top of the feed port blind plate 3 can work with the first nitrogen purging pipe 8 to purge and replace the raw material.

[0025] In this embodiment, the straight section of the first pipe segment 4 forms a 3.5° angle with the vertical direction, and the inclined section 62 of the second pipe segment forms a 7.5° angle with the vertical section 61, ensuring smooth material feeding and avoiding the occupation of a large space.

[0026] The side of the nitrogen purging box 1 is also provided with an isolation glove interface 11 for receiving isolation gloves; in this embodiment, there are two isolation glove interfaces 11 and two isolation gloves are provided accordingly. The isolation gloves ensure that the hands can directly contact the raw materials when handling them, and also ensure that the glove box is completely isolated from the outside world.

[0027] To ensure stable placement, a fixed support is provided at the bottom of the nitrogen purging box 1. The fixed support can be attached to the device support provided on the feeding funnel 2 to ensure the stability of the nitrogen purging box 1.

[0028] The nitrogen purging chamber 1 ensures that raw materials can be properly pretreated before being added to the reaction apparatus, while avoiding air interference with the product and ensuring operational safety. Raw materials and pretreatment tools can be placed through the top inlet of the nitrogen purging chamber 1. Nitrogen purging ensures that the nitrogen purging chamber is always filled with nitrogen. The nitrogen purging pipe interface on the nitrogen purging chamber allows the use of a second nitrogen purging pipe inside the nitrogen purging chamber for easy access and use. The second nitrogen purging pipe is equipped with a valve, which can be easily started and stopped at any time.
