Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of oil-blocking devices, specifically an oil-blocking device for a mechanically sealed reactor. Background Technology
[0002] In some chemical industries or laboratories, reaction vessels are frequently used. The main function of a reaction vessel is to stir several materials added to it, and simultaneously carry out a closed physical or chemical reaction under pressure and temperature to generate another new mixture or a new element. The structure of reaction vessels is generally the same, mainly consisting of a vessel body, a vessel lid, a stirring shaft, and impellers.
[0003] Since most reactors require certain pressures and temperatures during operation, they necessitate excellent sealing performance. As can be seen from the reactor's structure, most sealing surfaces can be sealed using sealing rings or gaskets, achieving good sealing results. The most difficult part to seal is the area between the stirring shaft and the reactor lid.
[0004] During operation, the stirring shaft rotates, and most reactors use mechanical seals. Mechanical seals mainly consist of a rotating ring and a stationary ring. The sealing surfaces between the rotating and stationary rings are ground to ensure excellent fit. During operation, a small amount of machine oil is injected into the sealing surface to form an oil film, which further enhances the sealing effect. The sealing pressure can reach over 1.6 MPa.
[0005] Because machine oil is injected between the sealing surfaces, it may slide down the stirring shaft and enter the material inside the reactor during operation, causing contamination. Therefore, improvements are needed. Utility Model Content
[0006] The purpose of this invention is to provide an oil-blocking device for a mechanically sealed reactor, which solves the problem that the oil may slide down the stirring shaft and contaminate the materials inside the reactor.
[0007] To achieve the above objectives, this utility model provides the following technical solution: an oil-blocking device for a mechanically sealed reactor, comprising a reactor body, a reactor cover at the top of the reactor body, a fixed seat fixedly connected to the top of the reactor cover, a connecting seat fixedly installed at the top of the fixed seat by threads, a connecting sleeve fixedly installed at the top of the connecting seat, a mechanical seal fixedly installed on the fixed seat by bolts, a stirring shaft rotatably connected inside the mechanical seal, the stirring shaft rotatably connected to the fixed seat and the reactor cover respectively, a connecting plate fixedly connected to the top of the inner wall of the reactor cover, an oil receiving box contacting the lower end of the connecting plate, a plug at the bottom of the oil receiving box, an oil-blocking plate fixedly installed on the outer side of the stirring shaft by a set screw, and a connecting mechanism provided on the connecting plate.
[0008] Preferably, the fixed base has a through groove inside, and a stirring shaft is rotatably connected inside the through groove. By designing the through groove, the stirring shaft can rotate inside the fixed base.
[0009] Preferably, a sealing sleeve is fixedly fitted onto the inner side of the oil receiving box, and the sealing sleeve contacts the connecting plate. By designing the sealing sleeve, the connection between the oil receiving box and the connecting plate can be sealed.
[0010] Preferably, a sealing ring is fixedly fitted onto the inner side of the oil baffle, and the sealing ring contacts the stirring shaft. By designing the sealing ring, the connection between the oil baffle and the stirring shaft can be sealed.
[0011] Preferably, the connecting mechanism includes a fixed rod, which is fixedly connected inside the connecting plate. A spring is provided on the outside of the fixed rod, and a slider is slidably sleeved on the outside of the fixed rod. The slider is slidably connected to the connecting plate. A ball is fixedly connected to one end of the slider, and the other end of the ball is fixedly connected to the connecting plate. A retaining ball is movably sleeved inside the other end of the slider and is movably connected to the connecting plate. A connecting post is movably sleeved on the outside of the retaining ball, and the connecting post is slidably connected to both the connecting plate and the oil receiving box. This connecting mechanism facilitates the disassembly and reassembly of the oil receiving box.
[0012] Preferably, one end of the spring is fixedly connected to the slider, and the other end of the spring is fixedly connected to the connecting plate. The spring is designed so that its force can be applied to the slider.
[0013] Preferably, the connecting post has a groove inside, and a retaining ball is movably fitted inside the groove. The groove design allows the retaining ball to slide relative to the connecting post.
[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0015] 1. This utility model, through the design of the oil baffle plate, connecting plate, and oil receiving box, ensures that when the sliding oil flows through the oil baffle plate, it is thrown into the oil receiving box under the centrifugal force of the rotating stirring shaft. The oil is blocked, preventing it from continuing to slide down the stirring shaft and into the material inside the reactor. Because of the added oil baffle device, the oil is blocked, completely preventing the oil from continuing to slide down the stirring shaft and into the material, thus ensuring that the material is not contaminated.
[0016] 2. This utility model, through the design of the insertion of the locking ball and the connecting column, can limit the connection column, thereby realizing the connection and use of the oil receiving box and the connecting plate. After the kettle cover is removed, the locking ball can be squeezed and pushed to separate from the connecting column by pulling the connecting column. Then the connecting column can be pulled out from the inside of the connecting plate and the oil receiving box, and the oil receiving box and the connecting plate can be separated, which facilitates the cleaning and maintenance of the collected oil.

A sealing ring 15 is fixedly fitted inside the oil baffle 14. The sealing ring 15 contacts the stirring shaft 7. By designing the sealing ring 15, the connection between the oil baffle 14 and the stirring shaft 7 can be sealed. A connecting mechanism 9 is provided on the connecting plate 10.
[0023] Please see Figure 1 , Figure 2 , Figure 3 The connecting mechanism 9 includes a fixed rod 91, which is fixedly connected inside the connecting plate 10. A spring 92 is provided on the outside of the fixed rod 91. One end of the spring 92 is fixedly connected to the slider 93, and the other end of the spring 92 is fixedly connected to the connecting plate 10. By designing the spring 92, the force of the spring 92 can act on the slider 93. The slider 93 is slidably sleeved on the outside of the fixed rod 91.

Then pull the connecting column 96 out of the connecting plate 10 and the oil collection box 11. The oil collection box 11 and the connecting plate 10 can be separated, which facilitates the cleaning and maintenance of the collected oil.
