Abstract
Description
Technical Field
[0001] This utility model relates to the field of alkylation reaction technology, and in particular to an automatic continuous feeding and temperature control device for alkylation reactions. Background Technology
[0002] Alkylation is an organic chemical reaction in which an alkyl group reacts with the active part of another molecule through a covalent bond to form an alkylated product. This reaction is usually carried out in the presence of a catalyst and is commonly used in petrochemicals, pharmaceuticals, and synthetic chemistry. When alkylation is carried out in a reaction vessel, the reaction is carried out under optimal conditions, such as the rate of reactant addition and reaction temperature, in order to improve the reaction efficiency of the product.
[0003] Chinese patent discloses an automatic continuous feeding and temperature control device for alkylation reactions (authorization announcement number CN215655137U). This patented technology achieves automatic continuous feeding of materials by using a variable frequency motor to drive a star-shaped feed valve. The controller interconnects and controls the reaction temperature, stirring speed, and feeding time and speed. By adjusting the feeding time, speed, and stirring speed in a timely manner based on the reaction temperature, the alkylation reaction is kept at a stable and reasonable temperature, resulting in a more complete and stable reaction, which is beneficial to improving product yield, product quality, and quality stability.
[0004] However, existing alkylation reactions often use a screw feeder, where materials enter from a hopper. When the hopper is full, this can easily cause blockage of the material entering the screw feeder, preventing feeding and thus affecting the alkylation reaction. Therefore, those skilled in the art have provided an automatic continuous feeding and temperature control device for alkylation reactions to solve the problems mentioned in the background.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] Please see Figure 1-4This utility model provides a technical solution for an automatic continuous feeding and temperature control device for alkylation reaction: it includes a reactor body 1, a reactor cover 2 disposed on the upper surface of the reactor body 1, and a temperature measuring mechanism 7 disposed on the outside of the reactor body 1. A feed pipe 42 is installed on the outside of the reactor cover 2. The upper end of the feed pipe 42 is connected to a spiral feeding pipe 4. A feeding motor 41 is disposed on one side of the spiral feeding pipe 4. A material box 43 is installed on the upper surface of the spiral feeding pipe 4. An mounting plate 5 is installed on the upper surface of the material box 43 by screws. An electric lifting rod 51 is disposed on the upper surface of the mounting plate 5. A lifting plate 52 is disposed below the mounting plate 5. Anti-blocking rods 53 are symmetrically disposed on the lower surface of the lifting plate 52. This arrangement uses the operation of the electric lifting rod 51 to make the lifting plate 52 rise and fall inside the material box 43. In this way, when rising and falling, the anti-blocking rods 53 will prevent blockage at the connection between the material box 43 and the spiral feeding pipe 4, thereby avoiding blockage and affecting the feeding operation.
[0025] A connecting sleeve 8 is installed on the outside of the reactor body 1. Electric telescopic rods 81 are symmetrically arranged on the outside of the connecting sleeve 8. A heating plate 6 is installed on the lower surface of the reactor body 1. Heating tubes 62 are symmetrically arranged on the upper surface of the heating plate 6 inside the reactor body 1. A heating plate 61 is installed inside the heating plate 6. The heating plate 61 in the heating plate 6 can improve the heating and temperature control inside the reactor body 1. At the same time, the heating tubes 62 are located inside the reactor body 1, which can also transfer the heat they generate through the inner wall of the reactor body 1 to its interior, so as to achieve the purpose of efficient temperature control.
[0026] like Figure 3 As shown, a first motor 3 is installed at the middle position of the upper surface of the reactor lid 2. The drive end of the first motor 3 is connected to a rotating shaft 31. A stirring paddle 32 is symmetrically arranged on the outer side of the rotating shaft 31. This arrangement utilizes the operation of the first motor 3 to make the stirring paddle 32 outside the rotating shaft 31 rotate. When it rotates, it can efficiently stir the material inside the reactor body 1, thereby improving the reaction efficiency of the material. This technology is a mature existing technology and will not be discussed in detail here.
[0027] like Figure 3 As shown, symmetrical limit holes are provided on the outer side of the reactor lid 2. The telescopic end of the electric telescopic rod 81 is embedded in the limit hole. This setting allows the telescopic end of the electric telescopic rod 81 to be embedded in the limit hole when it is operated, thus achieving the purpose of connecting the reactor body 1 and the reactor lid 2. In this way, it can also be disassembled for cleaning.
[0028] like Figure 4As shown, at least eight heating tubes 62 are symmetrically arranged inside the reactor body 1, and a resistance wire is installed inside the heating plate 61. This arrangement, using the heating tubes 62 and the heating plate 61, can transfer heat to the inside of the reactor body 1 and improve its temperature control efficiency.
[0029] like Figure 2 As shown, the drive end of the feeding motor 41 is connected to a conveying shaft inside the spiral feeding pipe 4. Spiral conveying blades are provided on the outside of the conveying shaft. This arrangement uses the operation of the feeding motor 41 to make the spiral conveying blades outside the conveying shaft rotate, and then the material in the material box 43 can be spirally fed into the interior of the reactor body 1 through the spiral conveying blades. This technology is existing technology and will not be discussed in detail here.
[0030] like Figure 2 As shown, the fixed end of the electric lifting rod 51 is installed on the upper surface of the mounting plate 5, and the upper surface of the lifting plate 52 is equipped with a fixing sleeve 54. The telescopic end of the electric lifting rod 51 is embedded in the fixing sleeve 54 and connected by screws. At least four anti-blocking rods 53 are symmetrically arranged on the lower surface of the lifting plate 52, and the lower end of the anti-blocking rods 53 is tapered. This arrangement uses the operation of the electric lifting rod 51 to make the lifting plate 52 rise and fall inside the material box 43, and when rising and falling, the anti-blocking rods 53 will rise and fall inside the material box 43 to insert the material, thereby achieving the purpose of loosening and unloading the material.
[0031] The working principle of this utility model is as follows: When using the automatic continuous feeding and temperature control equipment for alkylation reactions, a temperature measuring mechanism 7 is installed on the outside of the reactor body 1 to measure the temperature inside the reactor body 1. The feeding and stirring efficiency is improved by the first motor 3 and the feeding motor 41, so that the reaction temperature rises to the preset level. Simultaneously, to prevent blockage of the material hopper 43 during feeding, the operation of the electric lifting rod 51 causes the lifting plate 52 to rise and fall inside the material hopper 43. During this rising and falling, the anti-blocking rod 53 is positioned inside the material hopper 43. The material is inserted by lifting and lowering, loosening it and feeding it into the spiral feeding pipe 4. After entering, the material is spirally fed into the reactor body 1 by the feeding motor 41. After entering, the first motor 3 rotates the stirring paddle 32 to agitate the material. The heating plate 61 in the heating plate 6 can improve the heating and temperature control inside the reactor body 1. At the same time, the heating pipe 62 is located inside the reactor body 1, and the heat it generates can be transferred to the interior through the inner wall of the reactor body 1, achieving efficient temperature control and good practicality.
[0032] The first motor, feeding motor, electric lifting rod, and electric telescopic rod used in this utility model are all existing known electrical devices, and all can be purchased and used directly on the market. Their structure, circuit, and control principle are all existing known technologies. Therefore, the structure, circuit, and control principle of the device will not be described in detail here.
[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
