A highly efficient and convenient catalyst stirring device

Abstract

This utility model provides a highly efficient and convenient catalyst stirring device, including a lifting mechanism, a stirring mechanism, a base, and a fixing mechanism. The base has a U-shaped structure, and multiple roller sets are rotatably installed at equal intervals inside the base. The lifting mechanism is vertically mounted on the base, and the stirring mechanism is connected to the lifting end of the lifting mechanism. The fixing mechanism is used to fix the stirring tank. The roller sets inside the base enable easy transportation and positioning of the stirring tank. Combined with the fixing mechanism, the intensity of manual handling, operation, and monitoring can be greatly reduced, saving manpower. The lifting mechanism, in conjunction with the stirring mechanism, not only realizes the automatic and uniform descent of the stirring impeller and continuous stirring, but also accurately sets the stirring depth and automatically stops at the lowest position, effectively preventing damage to the tank or equipment due to operational errors or excessive descent, and ensuring production safety.

Description

Technical Field

[0001] This utility model relates to the field of catalyst stirring, and in particular to a highly efficient and convenient catalyst stirring device. Background Technology

[0002] The use of cyclohexene hydration to prepare cyclohexanone has become a preferred trend in the caprolactam industry. A crucial step in this production process is the reaction of cyclohexene and water with a catalyst to generate the target product, cyclohexanol. The reactor is a fluidized bed, and the catalyst itself is in a fine particulate state. During normal production or start-up and shutdown, some catalyst is lost with the reactor discharge. At this time, it is necessary to continuously add new catalyst to control the reaction conversion and maintain the solid catalyst content in the reactor. The hydrated catalyst is an aluminosilicate, which arrives at the plant in solid drums. The equipment needs to use a special agitator to stir the solid catalyst with water to form a liquid before adding it to the reactor. However, the agitator has a low degree of automation and requires constant manual operation. During operation, abnormalities often occur, such as catalyst spilling onto the surrounding ground, overheating and tripping of the agitator motor, and the agitator bearing misaligning due to the high-speed rotation of the impeller and scraping against the inner cylinder. Each drum of catalyst weighs 100 kg, making operation extremely inconvenient, delaying the optimal time for adding catalyst, deteriorating the reaction effect, and thus affecting production.

[0008] Preferably, it also includes a cover plate that covers the top opening of the mixing tank.

[0009] Preferably, the cover plate has an inlet channel corresponding to the stirring shaft, and a groove is provided on one side wall of the inlet channel. A sealing plate is slidably installed in the groove, and a spring is also installed in the groove. Under the action of the spring, the sealing plate enters the inlet channel.

Manually pulling the control handle opens the inlet channel, allowing the cover plate to close completely at the top opening of the mixing tank. This prevents splashing and overflow of liquid catalyst during high-speed mixing, avoiding material waste and pollution of the working environment. Releasing the control handle causes the sealing plate to reset under spring pressure, closing the inlet channel. The cover plate then becomes a complete seal, perfectly fitting the top opening of the mixing tank. The closed inlet channel cuts off the only possible outlet for overflow, effectively preventing material splashing and overflow. Attached Figure Description

[0013] To better explain and facilitate understanding of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] Please refer to Figures 1 to 2 This utility model provides a highly efficient and convenient catalyst stirring device, including a lifting mechanism 3, a stirring mechanism 4, a base 1, and a fixing mechanism 5; The base 1 has a U-shaped structure, and multiple roller sets 2 are rotatably installed at equal intervals inside the base 1; The lifting mechanism 3 is vertically mounted on the base 1; The stirring mechanism 4 is connected to the lifting end of the lifting mechanism 3; Fixing mechanism 5 is used to fix the mixing tank; In use, the multiple rollers allow the mixing tank to be quickly moved to the fixed position of the base 1. The mixing tank is fixed by the fixing mechanism 5, and then the lifting mechanism 3 drives the stirring mechanism 4 into the mixing tank to stir the catalyst inside the mixing tank.

[0015] In this application, the roller assembly 2 inside the base 1 enables easy transportation and positioning of the mixing tank. Combined with the fixing mechanism 5, it can significantly reduce the intensity of manual handling, operation and monitoring, saving human resources. The lifting mechanism 3, together with the mixing mechanism 4, not only realizes the automatic uniform descent of the mixing impeller and continuous mixing, but also accurately sets the mixing depth and automatically stops at the lowest position, effectively preventing damage to the tank or equipment due to operational errors or excessive descent, and ensuring production safety.

[0016] In this embodiment, the lifting mechanism 3 includes a pole 31, a lifting slide 33, and a lifting cylinder 32; The upright 31 is vertically mounted on the base 1; The lifting slide block 33 is slidably mounted on the upright 31; One end of the lifting cylinder 32 is connected to the base 1, and the piston rod of the lifting cylinder 32 is connected to the lifting slide 33; In use, the lifting cylinder 32 drives the lifting slide 33 to move up and down on the upright 31, thereby controlling the lifting and lowering of the stirring mechanism 4.

[0017] In this embodiment, the stirring mechanism 4 includes a stirring motor 41, a fixed frame 42, a stirring shaft 43, and a stirring blade 44; The fixed frame 42 is connected to the lifting slide 33 via a connecting rod; The stirring motor 41 is mounted on the fixed frame 42, and the stirring motor 41 is connected to the stirring shaft 43; The stirring blades 44 are mounted on the stirring shaft 43; In use, the stirring motor 41 drives the stirring blades 44 to rotate through the stirring shaft 43 to achieve stirring.

[0018] In this embodiment, the fixing mechanism 5 includes two semi-circular clamps arranged in pairs. One semi-circular clamp is fixedly connected to the upright 31, and the two semi-circular clamps are connected by bolts to form a closed fixing ring, which fixes the mixing tank.

[0019] refer to Figure 3 and Figure 4 In this embodiment, a cover plate 6 is also included. The cover plate 6 covers the top opening of the mixing tank.

An movable hole 64 corresponding to the control handle 63 is provided on the inner wall of the sliding groove 65. In use, manually pulling the control handle 63 opens the inlet channel 61. The inlet channel 61 on the cover plate 6 allows the cover plate 6 to close at the top opening of the mixing tank, preventing splashing and overflow of liquid catalyst during high-speed mixing, thus avoiding material waste and pollution of the working environment. Releasing the control handle 63 causes the closing plate 62 to reset under the action of the spring 66, closing the inlet channel 61. The cover plate 6 then changes from a "cover with a hole" to a "completely sealed cover," fitting perfectly against the top opening of the mixing tank. The closed inlet channel 61 cuts off its only possible outlet for overflow, effectively preventing material splashing and overflow.
