Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and more specifically, to an adjustable multi-channel chemical reaction vessel feeding device. Background Technology

[0002] Chemical reaction vessels are core equipment used in chemical production for carrying out chemical reactions. They typically consist of a vessel body, stirring device, heat transfer device (such as a jacket or internal coil), sealing structure, and inlet / outlet ports. The materials used are mostly stainless steel, titanium alloy, or enamel to adapt to the corrosiveness of different media. Their core function is to provide controllable temperature, pressure, and stirring conditions for chemical reactions. They are widely used in pharmaceuticals, petrochemicals, fine chemicals, and food processing, and can perform various reactions such as hydrogenation, nitration, polymerization, and crystallization.

[0003] Currently, the feed position of chemical reactors is fixed, and multiple chemical raw materials can only be added to the reactor sequentially, resulting in low feeding efficiency and severely restricting the overall processing efficiency. Furthermore, the fixed feed position easily causes localized accumulation of raw materials within the reactor, hindering thorough dispersion and mixing. This not only affects reaction efficiency but also easily triggers localized side reactions, reducing product quality and yield. Therefore, we propose an adjustable multi-channel chemical reactor feed device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide an adjustable multi-channel chemical reactor feeding device to solve the technical problem of fixed feeding position in current chemical reactors, which causes local accumulation of raw materials in the reactor.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable multi-channel chemical reactor feeding device, including a reactor body and a feeding mechanism provided on the reactor body. The upper end of the reactor body is provided with several feeding ports, and an extension hole is provided at the rear of the upper end of the reactor body. The upper end of the reactor body is provided with a first annular groove and a second annular groove, with the first annular groove located outside the second annular groove. The feeding mechanism includes an annular cover and a discharge trough. The upper end of the annular cover is provided with several feeding pipes and a feeding hopper. The lower end of the annular cover is provided with a sealing ring located outside the feeding pipes. The lower end of the discharge trough is provided with a first discharge pipe, a second discharge pipe, and a third discharge pipe.

[0006] Preferably, the upper outer surface of the reactor body is provided with a plurality of alignment arrows, the positions of which correspond to the positions of the feed inlet, and the lower end of the annular cover is provided with a plurality of directional arrows.

[0007] Preferably, a limiting ring is provided at the lower end of the annular cover, and a rubber layer is provided on the outer surface of the limiting ring. The limiting ring is located in the first annular groove and the second annular groove respectively, and the lower end of the annular cover is in contact with the upper end of the reactor body.

[0008] Preferably, each end of the feeding trough is provided with a mounting rod, the feeding trough is located inside the reactor body, and the end of the mounting rod is welded and fixed to the inner wall of the reactor body.

[0009] Preferably, the feeding trough is curved along its long axis, and the feeding trough is semi-circular in shape. Several partitions are provided at the upper end of the feeding trough, which divide the feeding trough into several sub-feeding troughs. The first feeding pipe is arranged vertically downward, and the second and third feeding pipes are arranged at a downward inclination. The end of the second feeding pipe is located on both sides of the center inside the reactor body, and the end of the third feeding pipe is located at the rear of the reactor body.

[0010] Preferably, a fixing rod is provided at the rear end of the feeding trough, and a spring and a damping rod are provided at the upper end of the tail of the fixing rod. The damping rod is located inside the spring, and a positioning ball is provided at the end of the spring and the damping rod. The positioning ball extends out of the reactor body from the extension hole. Several spherical grooves adapted to the size of the positioning ball are provided at the lower end of the annular cover. The spherical grooves are located at symmetrical positions of the feed pipe.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the design of an annular cover structure, combined with an adjustable feed inlet, enables the simultaneous feeding of multiple chemical raw materials, greatly shortening the feeding time and effectively improving the overall processing efficiency. Furthermore, the alignment arrows on the reactor body and the pointing arrows on the annular cover work together, allowing operators to intuitively and conveniently adjust the number and position of the feed inlets. The feeding method can be flexibly adjusted according to actual production needs, enhancing the applicability and flexibility of the device. The addition of a discharge trough prevents material accumulation and facilitates subsequent mixing. Simultaneously, the positioning structure, composed of a positioning ball, spring, and spherical groove, automatically positions the annular cover when the feed pipe connects to the feed inlet, preventing rotation during feeding and ensuring a stable and reliable feeding process. This solves the problem of fixed feed positions in current chemical reactors, which leads to localized accumulation of raw materials within the reactor.

[0013] 2. This utility model also designs a feeding trough structure, using a partition to divide the feeding trough into several distribution troughs. The distribution troughs feed materials through a first feeding pipe, a second feeding pipe, and a third feeding pipe set in different directions and positions, so that the various raw materials are distributed in different positions after entering the reactor, avoiding local accumulation of raw materials in the reactor, reducing the occurrence of local side reactions, and creating good conditions for the full dispersion and mixing of raw materials, thereby helping to improve product quality and yield.

Detailed Implementation

[0021] like Figures 1 to 6As shown, this utility model relates to an adjustable multi-channel chemical reactor feeding device, including a reactor body 101 and a feeding mechanism 200 provided on the reactor body 101. The upper end of the reactor body 101 is provided with a plurality of feed inlets 106, and an extension hole 105 is provided at the rear of the upper end of the reactor body 101. The upper end of the reactor body 101 is provided with a first annular groove 103 and a second annular groove 104. The first annular groove 103 is located outside the second annular groove 104. The feeding mechanism 200 includes an annular cover 201 and a discharge trough 207. The upper end of the annular cover 201 is provided with a plurality of feed pipes 202 and a feed hopper 203. The lower end of the annular cover 201 is provided with a sealing ring 205 located outside the feed pipes 202. The lower end of the discharge trough 207 is provided with a first discharge pipe 2073, a second discharge pipe 2074 and a third discharge pipe 2075 respectively. This invention allows for the simultaneous feeding of multiple raw materials by rotating the annular cover 201 to open several feed ports 106, thereby improving efficiency. The multi-channel feed pipe disperses the raw materials in different positions within the reactor, avoiding local accumulation, reducing side reactions, facilitating thorough mixing, and improving product quality and yield.

[0022] Specifically, the upper outer surface of the reactor body 101 is provided with several alignment arrows 102, the positions of which correspond to the positions of the feed inlets 106. The lower end of the annular cover 201 is provided with several directional arrows 204. The alignment arrows 102 correspond to the positions of the feed inlets 106. When the annular cover 201 is rotated, the directional arrows 204 correspond to the alignment arrows 102, and each directional arrow 204 corresponding to the alignment arrow 102 can open one feed inlet 106.

[0023] Furthermore, a limiting ring 2011 is provided at the lower end of the annular cover 201. The outer surface of the limiting ring 2011 is provided with a rubber layer. The limiting ring 2011 is located in the first annular groove 103 and the second annular groove 104 respectively. The lower end of the annular cover 201 is in contact with the upper end of the reactor body 101. The setting of the first annular groove 103 and the second annular groove 104, together with the limiting ring 2011, facilitates the rotation of the annular cover 201. In addition, the rubber layer on the outer surface of the limiting ring 2011 can also seal between the annular cover 201 and the reactor body 101. Together with the sealing ring 205, the sealing of the reactor body 101 can be guaranteed when the feed port 106 is closed.

[0024] It is worth noting that both ends of the feeding trough 207 are equipped with mounting rods 208. The feeding trough 207 is located inside the reactor body 101, and the ends of the mounting rods 208 are welded and fixed to the inner wall of the reactor body 101. When multiple raw materials are fed, rotating the annular cover 201 causes several feeding pipes 202 to correspond to several feeding ports 106. Multiple raw materials can be added into the reactor body 101 simultaneously through multiple feeding hoppers 203, which can effectively improve the efficiency of feeding multiple raw materials. The raw materials added into the reactor body 101 can fall into the corresponding distributing troughs 2072 on the feeding trough 207.

[0025] It is worth mentioning that the feeding trough 207 is curved along its long axis and is semi-circular in shape. Several baffles 2071 are provided at the upper end of the feeding trough 207, which divide the feeding trough 207 into several distribution troughs 2072. The first feeding pipe 2073 is set vertically downward, while the second feeding pipe 2074 and the third feeding pipe 2075 are set downward at an angle. The end of the second feeding pipe 2074 is located on both sides of the center inside the reactor body 101, and the end of the third feeding pipe 2075 is located at the rear inside the reactor body 101. When the raw materials are located in several distribution tanks 2072, different raw materials can be discharged into the reactor body 101 through the first discharge pipe 2073, the second discharge pipe 2074, and the third discharge pipe 2075 respectively. The raw materials entering from the first discharge pipe 2073 can be vertically downward. The ends of the two second discharge pipes 2074 are located on both sides of the center inside the reactor body 101. The raw materials discharged from the second discharge pipes 2074 can be located on both sides of the bottom center inside the reactor body 101. The end of the third discharge pipe 2075 is located at the rear of the reactor body 101. The raw materials discharged from the third discharge pipe 2075 can be located at the rear of the bottom inside the reactor body 101. The multiple raw materials entering the reactor body 101 are located in different positions, so that the multiple raw materials will not accumulate in the reactor, preventing local side reactions, facilitating subsequent full dispersion and mixing, and improving product quality and yield.

[0026] It is worth noting that a fixing rod 209 is provided at the rear end of the feeding trough 207. A spring 210 and a damping rod 211 are provided at the upper end of the tail of the fixing rod 209. The damping rod 211 is located inside the spring 210. A positioning ball 212 is provided at the end of the spring 210 and the damping rod 211. The positioning ball 212 extends out of the reactor body 101 from the extension hole 105. Several spherical grooves 206 that are adapted to the size of the positioning ball 212 are provided at the lower end of the annular cover 201. The spherical grooves 206 are located at symmetrical positions of the feed pipe 202. When the annular cover 201 is rotated to connect the feed pipe 202 with the feed port 106, the annular cover 201 will squeeze the positioning ball 212 to retract into the extension hole 105. When the feed pipe 202 is connected to the feed port 106, the positioning ball 212 can rise and be positioned in the spherical groove 206 under the action of the spring 210, which can automatically position the annular cover 201 and prevent the annular cover 201 from rotating during feeding.

[0027] Working Principle: This embodiment provides an adjustable multi-channel chemical reactor feeding device. In use, the annular cover 201 is first rotated by friction. Because the outer surface of the limiting ring 2011 at the lower end of the annular cover 201 is provided with a rubber layer, and the limiting ring 2011 is located in the first annular groove 103 and the second annular groove 104 at the upper end of the reactor body 101, the annular cover 201 can rotate while ensuring sealing. During rotation, the operator can observe the alignment arrow 102 on the upper outer surface of the reactor body 101 and the pointing arrow 204 at the lower end of the annular cover 201. When each pointing arrow 204 corresponds to the alignment arrow 102, the annular cover 201 rotates. The corresponding feed inlet 106 is opened, allowing adjustment of the number and position of the feed inlets 106. When multiple raw materials need to be fed, the annular cover 201 is rotated so that several feed pipes 202 correspond to several feed inlets 106. At this time, multiple raw materials can be added simultaneously through multiple feed hoppers 203. The raw materials pass through the feed hoppers 203, feed pipes 202, and feed inlets 106 in sequence, falling into the corresponding distribution troughs 2072 on the discharge trough 207 inside the reactor body 101. The discharge trough 207 is curved along its long axis and is semi-circular in shape. The baffle 2071 at its upper end divides the discharge trough 207 into several distribution troughs 2072. The raw materials in different distribution troughs 2072 are... The materials are discharged through the first discharge pipe 2073, the second discharge pipe 2074, and the third discharge pipe 2075 at the lower end. The first discharge pipe 2073 is vertically downward, allowing incoming materials to fall vertically. The second discharge pipe 2074 is located at the center sides of the reactor body 101, allowing discharged materials to fall at the bottom center sides of the reactor body 101. The third discharge pipe 2075 is located at the rear of the reactor body 101, allowing discharged materials to fall at the rear bottom of the reactor body 101. This system ensures that various materials enter the reactor body 101 and are located in different positions, effectively preventing material accumulation. To prevent local side reactions, facilitate subsequent thorough dispersion and mixing, and improve product quality and yield, during the process of the annular cover 201 rotating to connect the feed pipe 202 with the feed port 106, the annular cover 201 will squeeze the positioning ball 212 extending from the extension hole 105, causing it to retract into the extension hole 105. After the feed pipe 202 is accurately connected to the feed port 106, under the action of the spring 210 at the upper end of the fixed rod 209, the positioning ball 212 rises and gets into the spherical groove 206 at the lower end of the annular cover 201, which is symmetrical to the feed pipe 202, automatically positioning the annular cover 201 to prevent it from rotating during feeding and ensuring a stable and reliable feeding process.
