Description

Technical Field

[0001] This utility model relates to the field of surfactant production technology, specifically to a raw material dripping device for surfactant production. Background Technology

[0002] Surfactants, also known as interfacial surfactants, are compounds that reduce the surface tension or interfacial tension between two liquids, between a liquid and a gas, or between a liquid and a solid. Surfactant molecules possess unique amphiphilic properties: one end is a hydrophilic polar group, often referred to as a hydrophilic group or oleophobic group, sometimes figuratively called a hydrophilic head. In the production process of surfactants, the precise addition of raw materials is crucial for product quality and production efficiency. In surfactant production, the addition of each component is often done via single-tube, single-orifice dripping. However, under special circumstances, dripping reactions can easily lead to incomplete reactions, violent localized reactions, and high impurity levels, severely impacting the yield.

[0003] According to the description in the patent announcement (CN210906070U) of a raw material dripping device for surfactant production, the raw material dripping device for surfactant production includes a "dripping funnel, a drain pipe, and a collection hopper" to realize the dripping operation.

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] This raw material dropping device for surfactant production utilizes a dropping funnel, a drain pipe, and a collection hopper to achieve the dropping operation. During use, the device stores the raw material to be added under the action of the dropping funnel, and can only drop one type of raw material at a time. Furthermore, when the raw material enters the inclined tube section, the flow of the material cannot be controlled. If too much material is added, it will also affect the efficiency of the feeding and the quality of the reaction. Therefore, this device needs to be improved. Utility Model Content

[0008] The dripping mechanism includes a support frame, which is fixedly connected to the top of the reactor. A storage tank is fixedly connected to the top of the support frame. A concave frame is fixedly connected to the periphery of the storage tank. A cylinder is fixedly connected to the top of the concave frame.

A discharge pipe is fixedly connected to the bottom of the storage tank. The discharge pipe is fixedly connected to the inside of the reactor. A dripping plate is fixedly connected to the bottom of the discharge pipe. A connecting block is fixedly connected to the right side of the discharge pipe.

A first servo motor is fixedly connected to the bottom of the first rotating rod.

[0009] Preferably, a groove is provided on the inner side of the concave frame, and the sealing plate is slidably connected in the groove. The bottom of the sealing plate is in contact with the top of the storage box, which makes the movement of the sealing plate more stable under the action of the groove.

[0010] Preferably, the dripping plate has a through hole inside, and the through hole is circular, so that the raw material can be dripped through the through hole.

[0011] Preferably, the mounting base is fixedly connected to the rear side of the reactor, and the first servo motor is fixedly connected to the bottom of the mounting base, so as to ensure the stability of the first servo motor under the action of the mounting base.

[0012] Preferably, there are two sets of feeding pipes and dripping plates, which are fixedly connected to the bottom of the storage box and are separated inside the storage box, so that multiple raw materials can be dripped at the same time by setting two sets.

[0013] Preferably, the striking mechanism includes a load-bearing frame, which is fixedly connected to the periphery of the storage box. A support block is fixedly connected to the bottom of the load-bearing frame. A second servo motor is fixedly connected to the rear side of the support block.

[0014] Preferably, the second rotating rod is rotatably connected inside the support block, and the outer periphery of the cam is in contact with the right side of the connecting block, so as to facilitate the striking of the connecting block under the action of the cam, thereby realizing the striking of the feed pipe and the drip rack plate.

[0015] Compared with the prior art, this utility model provides a raw material dripping device for surfactant production, which has the following beneficial effects:

[0016] 1. This raw material dripping device for surfactant production, through its dripping mechanism, allows raw materials that do not require dripping to be fed into the reactor via a feeding pipe during surfactant production, while raw materials requiring dripping are fed into a storage tank. The storage tank is compartmentalized, allowing for the storage of multiple raw materials. A cylinder drives a sealing plate to move, sealing the top of the storage tank and facilitating cleaning of the tank after production, ensuring the quality of subsequent raw material storage. During the reaction process, a first servo motor drives a rotating disk fixedly connected to the top of a first rotating rod to rotate. The rotating disc moves the connecting shaft and concave frame via the connecting rod. Under the action of the concave frame, the baffle moves inside the feeding pipe. The rotation of the rotating disc causes the baffle to move back and forth, which can quantitatively feed the raw materials in the storage tank, avoiding excessive feeding at one time and affecting the reaction effect. The fed raw materials will enter the feeding pipe and be dripped into the reactor by the dripping plate. The raw materials are added to the reactor in a precise and continuous manner by dripping, which can ensure that the raw materials are evenly distributed during the reaction, thereby improving the reaction efficiency and product quality.

[0017] 2. The raw material dripping device for surfactant production, through a set-in striking mechanism, allows the cam to rotate under the action of the second servo motor and the second rotating rod when raw materials are added to the reactor through the storage tank and the feed pipe during surfactant production. The cam then strikes and vibrates the connecting block, thereby striking the feed pipe and the dripping plate. This striking helps to prevent the raw materials from clogging the feed pipe and the dripping plate, ensuring the smooth flow of the feed pipe and the dripping plate and improving the dripping effect.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] This utility model provides the following technical solution:

[0029] Example 1

[0030] Please see Figure 1-6 This utility model provides a technical solution: a raw material dripping device for surfactant production, including a reaction vessel 1, a dripping mechanism 2 is provided on the top of the reaction vessel 1, a feeding pipe 4 is fixedly connected to the top of the reaction vessel 1, and a tapping mechanism 3 is provided around the dripping mechanism 2;

[0031] The dripping mechanism 2 includes a support frame 21, which is fixedly connected to the top of the reactor 1. A storage tank 22 is fixedly connected to the top of the support frame 21. A concave frame 23 is fixedly connected to the periphery of the storage tank 22. A cylinder 24 is fixedly connected to the top of the concave frame 23. A sealing plate 25 is fixedly connected to the bottom of the cylinder 24. The sealing plate 25 is slidably connected to the inner side of the concave frame 23 and is located on the top of the storage tank 22. A discharge pipe 26 is fixedly connected to the bottom of the storage tank 22 and is fixedly connected to the inside of the reactor 1. A dripping mechanism is fixedly connected to the bottom of the discharge pipe 26. Plate 297, a connecting block 27 is fixedly connected to the right side of the feeding pipe 26, a baffle 28 is slidably connected inside the feeding pipe 26, a concave frame 29 is fixedly connected to the rear side of the baffle 28, a connecting shaft 291 is rotatably connected inside the concave frame 29, a connecting rod 294 is rotatably connected inside the connecting shaft 291, a rotating disk 292 is fixedly connected to the bottom of the connecting rod 294, a first rotating rod 295 is fixedly connected to the bottom of the rotating disk 292, a mounting base 293 is rotatably connected to the periphery of the first rotating rod 295, and a first servo motor 296 is fixedly connected to the bottom of the first rotating rod 295.

[0032] A groove is provided on the inner side of the concave frame 23. The sealing plate 25 is slidably connected in the groove. The bottom of the sealing plate 25 is in contact with the top of the storage box 22, which makes the movement of the sealing plate 25 more stable under the action of the groove. The dripping plate 297 has a through hole inside, and the through hole is circular, which facilitates the dripping of raw materials through the through hole. The mounting base 293 is fixedly connected to the rear side of the reactor 1. The first servo motor 296 is fixedly connected to the bottom of the mounting base 293, which ensures the stability of the first servo motor 296 under the action of the mounting base 293. There are two sets of feeding pipes 26 and dripping plates 297. The two sets of feeding pipes 26 and dripping plates 297 are fixedly connected to the bottom of the storage box 22, and the storage box 22 is divided, which allows multiple raw materials to be dripped at the same time by setting two sets.

[0033] Example 2

[0034] Please see Figure 1-6 Furthermore, based on Embodiment 1, the striking mechanism 3 includes a load-bearing frame 31, which is fixedly connected to the periphery of the storage box 22. A support block 33 is fixedly connected to the bottom of the load-bearing frame 31. A second servo motor 32 is fixedly connected to the rear side of the support block 33. A second rotating rod 35 is fixedly connected to the front side of the second servo motor 32. A cam 34 is fixedly connected to the periphery of the second rotating rod 35. The cam 34 is located on the right side of the connecting block 27. The second rotating rod 35 is rotatably connected to the inside of the support block 33. The periphery of the cam 34 is in contact with the right side of the connecting block 27, which facilitates striking the connecting block 27 under the action of the cam 34, thereby realizing the striking of the feed pipe 26 and the drip rack plate.

[0035] In actual operation, when this device is used, during the surfactant production process, raw materials that do not require dripping are fed into the reactor 1 through the feeding pipe 4, while raw materials that require dripping are fed into the storage tank 22. The storage tank 22 is divided to store multiple raw materials. Simultaneously, the cylinder 24 drives the sealing plate 25 to move, so that the bottom of the sealing plate 25 contacts the top of the storage tank 22, thus sealing the storage tank 22. When the reaction is in progress, the first servo motor 296 drives the rotating disk 292, which is fixedly connected to the top of the first rotating rod 295, to rotate. The rotating disk 292 drives the connecting shaft through the connecting rod 294. The concave frame 29 and the concave frame 29 can move the baffle 28 inside the feed pipe 26 under the action of the concave frame 29. The rotation of the rotating disk 292 causes the baffle 28 to move back and forth, so that the raw materials in the storage box 22 can be quantitatively fed, avoiding excessive feeding at one time and affecting the reaction effect. The fed raw materials will enter the feed pipe 26 and be dripped through the dripping plate 297, so that the raw materials enter the reaction vessel 1 for reaction by dripping. The dripping method can accurately and continuously add raw materials into the reaction vessel 1, and at the same time ensure that the raw materials are evenly distributed during the reaction, thereby improving the reaction efficiency and product quality.

[0036] Furthermore, during use, the feeding pipe 26 can be driven by the second servo motor 32 to rotate the cam 34 fixedly connected to the second rotating rod 35, causing the cam 34 to strike the connecting block 27, thereby striking the feeding pipe 26 and the dripping plate 297. This striking helps to prevent the raw material from clogging the feeding pipe 26 and the dripping plate 297, ensuring the smooth flow inside the feeding pipe 26 and the dripping plate 297 and improving the dripping effect. When production is completed and the inside of the storage box 22 needs to be cleaned, the cylinder 24 can drive the sealing plate 25 to move away from the top of the storage box 22, making it easier to clean the inside of the storage box 22.
