Description

Technical Field

[0001] This utility model belongs to the technical field of chemical solid-liquid separators, and relates to anti-clogging solid-liquid separators. Background Technology

[0002] In the industrial production of C5 hydrogenated petroleum resin, the active components in the raw materials are prone to side reactions such as C5 dimerization under reaction conditions. These reactions inevitably generate polymer particles with a diameter of 3-6 mm. If these solid impurities are not separated from the liquid product in a timely and effective manner, they will not only affect the purity and quality of the final resin product, but also cause many problems for subsequent processes. Currently, a separator is usually required in this process to remove the aforementioned solid impurities.

[0003] However, conventional separators commonly used in the industry currently face significant technical bottlenecks in practical applications. For example, due to the viscosity and concentrated size distribution of the generated polymer particles, they easily adhere and accumulate rapidly on the filter screen or filter media surface during filtration, causing equipment channel blockage, leading to a sharp decline in separation efficiency and even production interruption. Frequent blockage not only increases the number of shutdowns for cleaning but also causes material residue and waste during the cleaning process. At the same time, repeated backwashing operations to maintain production also exacerbate equipment wear and energy consumption, resulting in high maintenance and operating costs. To achieve a certain processing capacity and cope with the problem of easy blockage, conventional filters often need to be designed with a large filtration area, resulting in large equipment size and increased footprint, which limits their applicability for the renovation of existing production facilities or new projects with limited space.

[0004] The existing solid-liquid separation structure has become a key factor restricting the economic efficiency, continuity, and safety of C5 hydrogenated petroleum resin production. Unplanned shutdowns caused by equipment blockage increase production safety risks, while high maintenance costs and material losses directly affect the project's economic benefits.

[0005] Therefore, there is an urgent need to develop a new type of anti-clogging solid-liquid separator that can efficiently and continuously filter and separate polymer solid particles generated during the production process, effectively purify the products, significantly reduce the frequency of equipment clogging and material loss, thereby improving the economy of the entire process while ensuring safe and stable production operation. Utility Model Content

[0006] The purpose of this invention is to provide an anti-clogging solid-liquid separator, which solves the problems of easy clogging, low separation efficiency and difficult disassembly in the prior art.

[0007] The technical solution adopted by this utility model is an anti-clogging solid-liquid separator, including a separator cylinder, a feed inlet at the top of the separator cylinder, a cap fixed at the bottom, a solid outlet and a liquid outlet respectively at the cap, a ring seat on the inner wall of the separator cylinder, a filter screen assembly bolted to the ring seat, an insert base welded to a section of the filter screen assembly away from the ring seat, a solid outlet being inserted and connected to the insert base, and a first purging pipe fixed to the inner wall of the separator cylinder.

[0008] The features of this utility model also include: The ring seat is a one-piece molded ring, and it is fixed to the inner wall of the separator cylinder by welding or flange connection.

[0009] The filter assembly includes several Johnson screens, which are fan-shaped and arranged radially at an angle.

[0010] The filter assembly also includes curved horizontal seats, the number of which is the same as the number of Johnson mesh segments. Each curved horizontal seat is welded to the corresponding Johnson mesh and is detachably connected to the ring seat by bolts and nuts.

[0011] The filter assembly also includes a tapered welded base located at the end of the Johnson mesh away from the curved horizontal seat. The tapered welded base has the same number of segments as the Johnson mesh. Each tapered welded base segment is welded to the bottom of the corresponding Johnson mesh segment, and the other end of the tapered welded base is welded to the insert base.

[0012] Each Johnson screen has a frame strip welded to both sides, and adjacent Johnson screens are bolted together by the frame strips on the Johnson screens to form a detachable filter assembly.

[0013] The first purge pipe is located between the filter assembly and the liquid outlet. The first purge pipe is distributed in a circle around the central axis of the separator cylinder, and several purge holes are opened on the pipe wall of the first purge pipe.

[0014] The bottom of the first purging pipe is connected to the second purging pipe, which penetrates the end cap and is fixedly connected to the outer wall of the end cap.

[0015] The bottom of the second purging pipe is connected to an industrial pipe for gas transportation.

[0016] A sealing element is provided between the insertion base and the solid outlet.

[0017] The beneficial effects of this utility model are: This novel anti-clogging solid-liquid separator integrates filtration, purging, and separation into a single unit, enabling solid-liquid separation with a single reactor. This avoids the need for multiple devices or complex processes required in traditional methods, achieving "one-stop" separation and purification and simplifying the operation. The Johnson screen effectively intercepts solid particles, and its radially inclined design facilitates the sliding of solids under gravity and subsequent purging. The gas purging system, with its continuous or intermittent purging through small circumferential holes, effectively prevents fine particles from clogging the screen, avoiding the accumulation of solid particles on the screen surface and thus reducing separation efficiency. The fan-shaped Johnson screen is connected by frame strips and bolts, and the conical base is directly inserted into the solid outlet channel, allowing for convenient and quick disassembly, replacement, or cleaning of individual sections. This is crucial for handling materials prone to scaling and clogging, significantly reducing maintenance difficulty and downtime. Attached Figure Description

[0020] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0021] Anti-clogging solid-liquid separators, such as Figure 1 As shown, the separator includes a separator cylinder 12, with a feed inlet 9 at the top and a cap 10 fixedly connected to the bottom. The cap 10 has a solid outlet 1 and a liquid outlet 11. A ring seat 7 is provided on the inner wall of the separator cylinder 12. A filter screen assembly is bolted to the ring seat 7. An insert base 2 is welded to a section of the filter screen assembly away from the ring seat 7. The insert base 2 is connected to the solid outlet 1. A first purging pipe 4 is also fixedly connected to the inner wall of the separator cylinder 12.

[0022] like Figure 2As shown, the ring seat 7 is an integrally formed ring, and the ring seat 7 is fixed to the inner wall of the separator cylinder 12 by welding or flange connection.

[0023] The filter assembly includes several Johnson mesh 5 pieces, which are fan-shaped and arranged radially at an angle.

[0024] The filter assembly also includes arc-shaped horizontal seats 8, the number of which is the same as the number of segments of the Johnson mesh 5. Each arc-shaped horizontal seat 8 is welded to the corresponding Johnson mesh 5 and is detachably connected to the ring seat 7 by bolts and nuts.

[0025] The filter assembly also includes a conical welding base 3, which is located at the end of the Johnson mesh 5 away from the arc-shaped horizontal seat 8. The number of segments of the conical welding base 3 is the same as the number of segments of the Johnson mesh 5. Each segment of the conical welding base 3 is welded to the bottom of the corresponding Johnson mesh 5. The other end of the conical welding base 3 is welded to the insert base 2.

[0026] Each Johnson mesh 5 has a frame strip 6 welded to both sides. Adjacent Johnson meshes 5 are bolted together by the frame strip 6 on the Johnson mesh 5 to form a detachable filter assembly.

[0027] like Figure 3 As shown, the first purge pipe 4 is located between the filter assembly and the liquid outlet 11. The first purge pipe 4 is distributed circumferentially around the central axis of the separator cylinder 12, as follows: Figure 4 As shown, the first purging pipe 4 has several purging holes 13 on its pipe wall for purging.

[0029] The bottom of the second purging pipe 14 is connected to an industrial pipe for gas transportation.

[0030] A sealing element is provided between the insertion base 2 and the solid outlet 1.

[0031] The working principle of this anti-clogging solid-liquid separator: Liquid containing impurity particles enters the anti-clogging solid-liquid separator through inlet 9. The liquid then passes through multiple radially inclined Johnson screens 5. The gap structure of the Johnson screens 5 allows the liquid to pass through while simultaneously trapping solid particles larger than a certain diameter. The trapped solid particles move downwards along the surface of the Johnson screens 5 under the combined action of liquid flow and gravity, eventually converging at the conical welded base 3. The solid particles then enter the insertion base 2 through the conical welded base 3 and are subsequently conveyed to the solid outlet 1 for periodic centralized discharge. Simultaneously, the liquid passing through the Johnson screens 5 enters the end cap 10 and is then discharged from the system through the liquid outlet 11, thus completing the efficient solid-liquid separation process. This anti-clogging solid-liquid separator, through the inclined multi-plate design of the Johnson screens 5, ensures an effective filtration area while facilitating installation and maintenance. It also utilizes the synergistic effect of gravity and fluid dynamics to achieve continuous separation and separate discharge of the solid and liquid phases.
