Description

Technical Field

[0001] This utility model belongs to the technical field of vacuum drying equipment, specifically relating to a vacuum spiral drying mechanism for materials with no dead angles. Background Technology

[0002] With the increasing demands for material drying quality and efficiency in the chemical, food, and pharmaceutical industries, vacuum spiral dryers are widely used due to their advantages of low-temperature drying and high efficiency.

[0003] However, the discharge sealing structure of existing drying equipment generally suffers from problems such as insufficient sealing and dead corners where materials remain: traditional flat sealing plugs do not fit tightly with the dryer discharge port, which can easily lead to vacuum leakage and affect drying efficiency; moreover, materials can easily remain around the sealing plug and on the inner wall of the discharge port, which not only causes incomplete drying but also increases the difficulty of cleaning the equipment.

[0004] Therefore, there is an urgent need for a vacuum spiral drying mechanism that can dry materials without dead angles, in order to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to propose a vacuum spiral drying mechanism for materials with no dead angles, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a vacuum spiral drying material drying mechanism without dead angles, including a discharge pipe.

[0007] This utility model further illustrates that the lower end of the discharge pipe is connected to the hydraulic cylinder via a flange. The hydraulic cylinder includes a cylinder body and a hydraulic rod. An arc-shaped sealing plug is bolted to the top of the hydraulic rod. The arc-shaped sealing plug has multiple sealing grooves around its periphery, and the top of the arc-shaped sealing plug is an arc-shaped sealing surface.

[0008] The present invention further describes that the discharge pipe has a hollow tubular structure, and the upper end of the discharge pipe is detachably and sealed to the discharge port of the dryer through a flange assembly. A discharge inclined pipe is provided in the upper middle part of the side wall of the discharge pipe, and the discharge inclined pipe is connected to the inner cavity of the discharge pipe.

[0009] This utility model further illustrates that an overflow port is provided at the lower end of the side wall of the discharge pipe.

[0010] This utility model further illustrates that the rod end of the cylinder is fixedly connected to the end of the discharge pipe via a flange.

[0011] This utility model further illustrates that the curvature of the arc-shaped sealing surface is exactly the same as the curvature of the inner wall of the discharge port of the dryer body.

[0012] This utility model further illustrates that an elastic sealing ring is fitted onto the multi-layer sealing groove.

[0013] Compared with the prior art, the beneficial effects achieved by this utility model are as follows: This utility model adopts a combination design of arc-shaped sealing plug and hydraulic cylinder, which achieves precise sealing through hydraulic drive. The multi-layer sealing groove and elastic sealing ring ensure the stability of the vacuum environment.

[0019] The following detailed, non-limiting description of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-3This utility model provides a technical solution: a vacuum spiral drying mechanism for materials without dead angles, including a discharge pipe 1; the discharge pipe 1 has a hollow tubular structure, and the upper end of the discharge pipe 1 is detachably and sealed to the discharge port of the dryer through a flange assembly to ensure the system's sealing during the drying process; a discharge inclined pipe 11 is provided on the side wall of the discharge pipe 1 at the upper middle position, the discharge inclined pipe 11 is connected to the inner cavity of the discharge pipe 1, and its inclination angle is optimized according to the material characteristics and discharge requirements to facilitate the smooth discharge of materials; the other end of the discharge pipe 1 is connected to a hydraulic cylinder 2 through a flange, and an overflow port 12 is provided at the lower end of the side wall of the discharge pipe 1. The overflow port 12 is used to balance the internal air pressure of the mechanism to ensure the smooth operation of each component.

[0021] The hydraulic cylinder 2 includes a cylinder body 21 and a hydraulic rod 22. The rod end of the cylinder body 21 is fixedly connected to the end of the discharge pipe 1 through a flange to ensure the stability of the connection. An arc-shaped sealing plug 3 is bolted to the top of the hydraulic rod 22. The arc-shaped sealing plug 3 has multiple sealing grooves 31 around its periphery. An elastic sealing ring 32 is fitted on the sealing groove 31. The elastic sealing ring 32 can be made of elastic sealing materials such as rubber and silicone. By stacking multiple layers, the sealing effect is enhanced to prevent material or gas leakage. The top of the arc-shaped sealing plug 3 is an arc-shaped sealing surface 33. The curvature of the arc-shaped sealing surface 33 is exactly the same as the curvature of the inner wall of the discharge port of the dryer body, so that a seamless connection can be achieved when they are fitted together.

[0022] Working principle:

[0023] When this drying mechanism is connected to the dryer and is in the closed state, the hydraulic rod 22 of the hydraulic cylinder 2 extends and pushes the arc-shaped sealing plug 3 upward until the arc-shaped sealing surface 33 tightly fits the inner wall of the dryer's discharge port. Since the arc-shaped sealing surface 33 is consistent with the curvature of the dryer body, it can completely cover the inner area of ​​the discharge port, eliminating the dead corners present in traditional right-angle connections. This ensures that the material will not accumulate in the corners of the discharge port during the operation of the dryer, thereby ensuring the uniformity of drying and avoiding the problem of incomplete drying caused by material retention.

[0024] When the drying process is complete and material needs to be discharged, hydraulic cylinder 2 controls hydraulic rod 22 to retract, causing the arc-shaped sealing plug 3 to descend. During the descent, as the lower end of the discharge inclined pipe 11 of the discharge pipe 1 approaches the initial position of the arc-shaped sealing plug 3, the space inside the discharge pipe 1 changes as the sealing top descends, generating a certain amount of air pressure. At this time, the overflow port 12 located at the lower end of the side wall of the discharge pipe 1 plays a role in timely discharging the internal air pressure, balancing the internal and external pressures, and ensuring that the arc-shaped sealing plug 3 can descend smoothly until the arc-shaped sealing surface 33 is lower than the position of the discharge inclined pipe 11. At this point, the material can be smoothly discharged through the discharge inclined pipe 11.

[0025] Through the above structural design, the drying mechanism of this utility model can effectively eliminate the dead corner of the dryer outlet, ensure uniform drying of materials, and balance the air pressure through the overflow port 12 during discharge to ensure the smoothness of the discharge process. It has the advantages of reasonable structure, good sealing effect and high drying uniformity.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
