Description

Technical Field

[0001] This utility model relates to a reaction vessel, specifically an external bottom bearing with a discharge port. Background Technology

[0002] Traditional reactors with external bottom bearings are completely sealed. The bottom bearing is located outside the center of the head, so the discharge port can only be opened on the side of the head, resulting in material remaining in the center of the head, which cannot be completely emptied during discharge. Utility Model Content

[0003] To address the shortcomings of the existing technology, this utility model provides an external bottom bearing with a discharge port. This utility model combines the bottom bearing and the discharge port, which not only satisfies the installation of the stirring shaft but also completely discharges the excess material. It has a simple structure and low cost.

[0004] To achieve the above technical objectives, the present invention adopts the following technical solution: an external bottom bearing with a discharge port, comprising a short section, multiple connecting blocks, and a bearing seat. The short section is fixed outside the central hole of the end cap, and the bearing seat is coaxially located inside the short section. One end of each of the multiple connecting blocks is fixed to the inner wall of the short section, and the other end is fixed to the outer wall of the bearing seat. A discharge port A is formed between two adjacent connecting blocks. The discharge port A communicates with the interior of the reactor and with a discharge port valve.

[0005] The short section has an upper flange at one end and a lower flange at the other end. The upper flange is connected to the flange of the end cap, and the lower flange is used to connect to the discharge port valve.

[0006] The lower end of the bearing housing is located inside the short section, forming an accommodating space below the bearing housing, and the accommodating space is connected to the discharge port A.

[0007] The connecting blocks are in two sets, located at the upper and lower ends of the bearing seat respectively, and the positions of the two sets of connecting blocks are vertically corresponding.

[0008] Each group consists of 4 connecting blocks, evenly distributed around the circumference.

[0009] The bearing housing is provided with a PTFE bushing, and the bushing and stirring shaft are installed inside the PTFE bushing.

[0010] In summary, this utility model achieves the following technical effects:

[0011] This utility model combines the bottom bearing and the discharge port, which not only satisfies the installation of the stirring shaft, but also completely discharges the excess material. The structure is simple and the cost is low. Attached Figure Description

[0014] The present invention will be further described in detail below with reference to the accompanying drawings.

[0015] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0020] Example:

[0021] Figure 1 It is an external bottom bearing with a discharge port. Figure 2 This is a cross-sectional view of the bottom bearing, including a short section 4, multiple connecting blocks 7, and a bearing seat 6. The short section 4 is fixed outside the central hole of the end cap 3. The bearing seat 6 is coaxially located inside the short section 4. One end of each of the multiple connecting blocks 7 is fixed to the inner wall of the short section 4, and the other end is fixed to the outer wall of the bearing seat 6. An outlet A is formed between two adjacent connecting blocks 7. The outlet A is connected to the inside of the reactor and to the outlet valve.

[0022] This invention places the bottom bearing on the outside of the center hole of the bottom head of the reactor, and there is a discharge port between the bearing seat and the short section. The bottom head 3 does not need to open a discharge port on the side of the head. This invention can discharge directly from the bottom bearing position, combining the bottom bearing and the discharge port into one, and the discharge is sufficient, without leaving bottom material inside the head.

[0023] The short section 4 is provided with an upper flange 8 at one end and a lower flange 10 at the other end. The upper flange 8 is connected to the flange of the end cap 3, and the lower flange 10 is used to connect the discharge port valve.

[0024] The short section adopts the form of a sleeve, which serves as an outer shell to surround the bottom bearing and form a discharge port, thus protecting the internal bottom bearing structure and allowing material to be discharged.

[0025] The lower end of the bearing seat 6 is located inside the short section 4, and a receiving space 11 is formed below the bearing seat 6. The receiving space 11 is connected to the discharge port A.

[0026] The length of the bearing housing 6 is less than the length of the short section, and the two are flush at the top. Therefore, the short section is longer at the bottom, leaving a certain space, namely the accommodating space 11, through which the material can be discharged directly through the valve without any material remaining, and the material is discharged cleanly.

[0027] like Figure 2As shown, there are two sets of connecting blocks 7, located at the upper and lower ends of the bearing seat 6 respectively, and the positions of the two sets of connecting blocks 7 are vertically corresponding.

[0028] Each group consists of 4 connecting blocks 7, evenly distributed around the circumference.

[0029] The system has 8 connecting blocks in total, with 4 at the top and 4 at the bottom, which is relatively stable. The discharge port A between two adjacent connecting blocks is relatively large, which facilitates material discharge.

[0030] The bearing housing 6 is provided with a PTFE bushing 9, and the bushing 2 and the stirring shaft 1 are installed inside the PTFE bushing 9.

[0031] This application adds four connecting blocks to the bottom bearing, and welds the short section to the bearing housing through the four connecting blocks, for a total of eight connecting blocks. The gaps between them allow material to be discharged, and the material can be completely emptied without any residue.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
