Description

Technical Field

[0001] This utility model relates to the field of feeding technology for acyl chloride production, specifically to an automatic feeding device for acyl chloride production. Background Technology

[0002] In the industrial production of acyl chloride compounds, precise feeding of raw materials is crucial for ensuring reaction efficiency and safety. Traditional feeding devices often employ open or semi-automatic structures, which have the following significant drawbacks:

[0003] 1. Acyl chloride raw materials are volatile and highly corrosive. Manual feeding or ordinary conveying equipment can easily lead to the leakage of irritating gases, which can endanger the operating environment and personnel health.

[0004] 2. Powdered or granular raw materials are prone to caking due to moisture in the hopper. Traditional gate-type feeding mechanisms do not close tightly and lack anti-blocking measures, resulting in interruption of material transmission and cross-contamination.

[0005] 3. The discharge port and the feed end of the reaction equipment are often rigidly connected by flange bolts. When changing containers, the machine must be stopped for disassembly, which seriously affects the continuous production rhythm.

[0006] 4. The hopper opening and closing relies on manual operation, making it difficult to achieve quantitative feeding and easily causing batch quality fluctuations.

[0007] Therefore, to address the aforementioned technical issues, a specialized feeding device with multiple sealing functions, anti-clogging vibration material control, rapid docking, and automated control is designed to meet the safety, continuity, and stability requirements of acyl chloride production. Utility Model Content

[0008] The purpose of this invention is to provide an automatic feeding device for acyl chloride production, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an automatic feeding device for acyl chloride production, comprising a frame, a feeding hopper, a receiving hopper, and a discharging hopper, characterized in that: the frame is suspended and fixedly supports the receiving hopper; the receiving hopper is connected to the feeding hopper and the discharging hopper at the top and bottom respectively; the feeding hopper is provided with a first cavity and a second cavity, and the cavities are separated by a partition; a first hydraulic cylinder is provided on one side of the bottom of the first cavity; the output end of the first hydraulic cylinder is connected to the middle of an L-shaped transmission rod; the two ends of the transmission rod are rotatably connected to the two sides of the bottom of the first cavity, and an arc-shaped plate is fixedly connected to its surface; the arc-shaped plate covers the bottom of the first cavity and is opened and closed by the first hydraulic cylinder.

[0010] The bottom of the second cavity is inclined with a pouring plate, and a small vibration motor is provided at the bottom of the pouring plate. One end of the pouring plate is suspended above the receiving hopper. The bottom of the receiving hopper is provided with a sealing component, which is located inside the feeding hopper. The outer side of the bottom of the feeding hopper is provided with a fastening mechanism for connecting the feed port of the next process.

[0011] Preferably, the sealing assembly includes a second hydraulic cylinder, a rotating shaft, a sealing plate, a connecting plate, and a connecting rod. The bottom of the receiving hopper is provided with rotating shafts on both sides, the rotating shafts pass through the sealing plate, the end of the sealing plate is connected to the connecting rod, the other end of the connecting rod is connected to both sides of the connecting plate by a pin, the top center of the connecting plate is fixedly connected to the output end of the second hydraulic cylinder, and the second hydraulic cylinder is fixedly disposed on one side of the receiving hopper.

[0012] Preferably, the fastening assembly includes a third hydraulic cylinder, a second rotating shaft, a second connecting rod, and a fastening sleeve. The third hydraulic cylinder is provided on both sides of the outer side of the hopper. The output end of the third hydraulic cylinder is connected to the second rotating shaft. Two second connecting rods are sleeved on the surface of the second rotating shaft. The ends of the two second connecting rods are fixedly connected to the arc-shaped fastening sleeve.

[0013] Preferably, a control panel is provided on one side of the frame for controlling the opening and closing of electrical components in the feed hopper, receiving hopper, and discharge hopper.

[0014] Preferably, the sealing plate half of the sealing assembly is disposed inside the hopper.

[0015] Preferably, the frame is equipped with side doors around the fixed receiving hopper, which can be opened to observe the operation of the internal working components.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model employs a first and second chamber design separated by a partition in the feeding hopper. An arc-shaped plate sealing mechanism driven by a first hydraulic cylinder is installed at the bottom of the first chamber. This arc-shaped plate can tightly cover and open and close the bottom of the first chamber, forming an effective first seal, which significantly reduces the volatilization and escape of raw materials in the initial feeding stage. A sealing component is installed at the bottom of the receiving hopper. This component is driven by a second hydraulic cylinder, which drives the sealing plate to rotate around the rotating shaft through a connecting rod and a connecting plate, realizing the precise opening and closing of the feeding channel. This ensures that the highly corrosive and volatile gases generated during the temporary storage and transfer of materials are effectively confined inside the device, reducing the risk of irritating gas leakage and protecting the health of operators and the safety of the production environment.

[0018] 2. This utility model integrates a small vibration motor under the tilted pouring plate at the bottom of the second cavity. When the material (especially powdered or granular acyl chloride raw materials that are prone to deliquescence and caking) flows through the pouring plate, the vibration force generated by the vibration motor can effectively prevent the material from accumulating or clumping on the plate surface, ensuring that the material slides smoothly and evenly into the receiving hopper.

[0019] 3. The fastening assembly (including a third hydraulic cylinder, a second rotating shaft, a second connecting rod, and an arc-shaped fastening sleeve) is set on the outer side of the bottom of the hopper. Through the extension and retraction of the third hydraulic cylinder, the second connecting rod drives the two arc-shaped fastening sleeves to open and close, so that the device can quickly and firmly fasten or loosen the feed port flange (or other standard interface) of the next process reactor, realizing quick connection and separation without bolt disassembly.

[0025] Although this invention may be described with respect to a particular application or industry, those skilled in the art will recognize its broader applicability. Those skilled in the art will understand that terms such as "above," "below," "upward," "downward," etc., are used to describe the drawings and not to indicate a limitation on the scope of the invention as defined by the appended claims. Any numerical designations such as "first" or "second" are merely illustrative and not intended to limit the scope of the invention in any way.

[0026] like Figures 1 to 4As shown in this embodiment, an automatic feeding device for acyl chloride production includes a frame 1, a feeding hopper 2, a receiving hopper 3, and a discharging hopper 4. The frame 1 is a stainless steel frame that is suspended and fixed to support the receiving hopper 3. The feeding hopper 2 is fixedly installed on the top of the frame 1, directly above the receiving hopper 3. The inside of the feeding hopper 2 is divided into two independent spaces, a first cavity 21 and a second cavity 22, by a vertically arranged partition 5. The bottom sides of the first cavity 21 are rotatably connected to the two ends of an L-shaped transmission rod 7 through bearing seats. The output end of the first hydraulic cylinder 6 is hinged in the middle of the transmission rod 7, and an arc-shaped plate 8 is welded to its surface. The arc-shaped plate 8 matches the bottom contour of the first cavity 21. In the initial state, the arc-shaped plate 8 tightly covers the bottom of the cavity under the pushing state of the first hydraulic cylinder 6, forming a seal. When feeding, the first hydraulic cylinder 6 retracts, causing the transmission rod 7 to rotate, which drives the arc-shaped plate 8 to flip and open, allowing the material to fall.

[0027] The bottom of the second cavity 22 is inclined to install a pouring plate 9. A small vibration motor 10 is fixed at the bottom of the pouring plate 9. The end of the pouring plate 9 extends to the top of the receiving hopper 3. The small vibration motor 10 vibrates slightly to effectively prevent the material from accumulating or clumping on the plate surface, ensuring that the material slides smoothly and evenly into the receiving hopper.

[0028] The sealing assembly 11 includes a second hydraulic cylinder 111, a rotating shaft 112, a sealing plate 113, a connecting plate 114, and a connecting rod 115. The rotating shaft 112 is welded to both sides of the bottom of the receiving hopper 3. The sealing plate 113 passes through the rotating shaft 112 through a bushing. The end of the sealing plate 113 is pinned to the connecting rod 115. The upper end of the connecting rod 115 is pinned to both sides of the connecting plate 114. The second hydraulic cylinder 111 is fixed to the side wall of the receiving hopper 3. Its piston rod is vertically connected to the center of the connecting plate 114. When the second hydraulic cylinder 111 extends, it pushes the connecting plate 114 to move downward. The connecting rod 115 pulls the sealing plate 113 to rotate around the rotating shaft 112 to open. When it retracts, it reverses the action to achieve sealing.

[0029] The fastening assembly 12 includes a third hydraulic cylinder 121, a second rotating shaft 122, a second connecting rod 123, and a fastening sleeve 124. The third hydraulic cylinder 121 is symmetrically installed on the outer wall of the hopper 4. Its piston rod is hinged to the second rotating shaft 122. The second rotating shaft 122 is fitted with two second connecting rods 123. The ends of the connecting rods 123 are welded with semi-circular fastening sleeves 124. When the third hydraulic cylinder 121 extends, the rotating shaft 122 rotates when it retracts, driving the fastening sleeve 124 to fasten the flange of the reactor inlet. When it is driven, it is released. The control panel 13 is installed on the side of the frame 1, which integrates the hydraulic system and the start / stop button of the vibration motor. The frame 1 around the receiving hopper 3 is provided with an openable side door 14, which facilitates the maintenance of the sealing assembly 11 and the observation of the internal status.

[0030] Working principle: Acyl chloride raw material is fed into feed hopper 2, volatile raw materials are stored in the first chamber 21, the first hydraulic cylinder 6 is activated, pushing the L-shaped transmission rod 7 to rotate, causing the arc plate 8 to flip and open, the material falls into the receiving hopper 3 and immediately resets and seals, preventing gas from escaping, the powdered raw material enters the second chamber 22, the vibration motor 10 runs continuously, the high-frequency micro-vibration of the pouring plate 9 makes the material slide evenly into the receiving hopper 3, avoiding the plate surface from agglomeration and blockage. When the receiving hopper 3 temporarily stores material, the sealing plate 113 is driven by the second hydraulic cylinder 111 to keep it closed. When the hydraulic cylinder is in a horizontal closed state (retracted), the lower half of the sealing plate 113 is embedded inside the feeding hopper 4, forming an airtight barrier. When feeding is required, the second hydraulic cylinder 111 extends and pulls down the connecting rod 115 through the connecting plate 114, forcing the sealing plate 113 to rotate downward around the rotating shaft 112, opening the feeding channel. The third hydraulic cylinder 121 tightens simultaneously, driving the second rotating shaft 122 to rotate, which in turn drives the two arc-shaped fastening sleeves 124 to hug the reactor inlet flange, achieving a quick sealing connection. The material enters the reactor through the feeding hopper 4.

[0031] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
