Liquid-solid separation device for sulfur foam pretreatment

Abstract

This utility model relates to the technical field of liquid-solid separation devices, specifically a liquid-solid separation device for sulfur foam pretreatment, including a tank. A fixing ring is provided on the inner wall of the tank, and a filter cylinder is placed on the fixing ring. A motor drives a transmission shaft to rotate, which in turn drives an eccentric wheel to rotate within a connecting frame. The eccentric wheel then drives two sets of sliding rods on both sides of the connecting frame, causing the two sets of sliding rods to slide back and forth within two sets of fixed seats. This causes two sets of rubber impact blocks to impact the filter cylinder, and the impact-generated vibration energy causes sulfur particles attached to the filter pores to fall off, thereby restoring the permeability of the filter pores. This enables online cleaning, ensuring the continuity of the liquid-solid separation process and improving the operating efficiency and stability of the device.

Description

Technical Field

[0001] This utility model relates to the technical field of liquid-solid separation devices, specifically a liquid-solid separation device for sulfur foam pretreatment. Background Technology

[0002] In industrial production processes such as coal chemical engineering and natural gas purification, a large amount of sulfur-containing waste liquid is generated. After treatment, this waste liquid forms sulfur foam. The pretreatment of sulfur foam is a key step in subsequent sulfur recovery and resource reuse. Liquid-solid separation, as the core step of pretreatment, directly affects the stability and economy of the entire production process. In the liquid-solid separation process of sulfur foam, the filter cartridge is a commonly used core component. It relies on its porous structure to filter the sulfur foam and achieve the separation of liquid and solid sulfur particles.

[0003] The solid sulfur particles in existing sulfur foam are characterized by uneven particle size, high viscosity, and easy agglomeration. During filtration, these particles easily adhere to the surface of the filter pores of the filter cartridge, and may even enter the interior of the pores. As the filtration time increases, the filter pores gradually become clogged, leading to a sharp increase in filtration resistance. This not only significantly reduces the liquid-solid separation efficiency and throughput, but may also affect the safe operation of the equipment due to excessive pressure. To solve the filter cartridge clogging problem, traditional methods often involve manual cleaning or periodic replacement of the filter cartridge. However, this method not only requires interrupting the production process, increasing labor costs and equipment downtime, but also makes it difficult to achieve continuous and stable filtration operations, severely restricting the continuity and automation level of industrial production. Therefore, we propose a liquid-solid separation device for sulfur foam pretreatment. Utility Model Content

[0004] The purpose of this invention is to provide a liquid-solid separation device for sulfur foam pretreatment to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A liquid-solid separation device for sulfur foam pretreatment includes a tank, a fixing ring is provided on the inner wall of the tank, a filter cylinder is placed on the fixing ring, an impact component is provided on the top of the tank, and the tank is connected to the impact component through the filter cylinder.

[0007] The impact assembly includes a fixed plate fixedly connected to the top of the tank. A motor is bolted to the top of the fixed plate. A drive shaft is fixedly connected to the output end of the motor. An eccentric wheel is fixedly connected to the bottom of the drive shaft. Two sets of fixed seats are symmetrically fixedly connected to the inner walls of the filter cylinders on both sides of the eccentric wheel. A sliding rod is slidably connected inside the fixed seat. A rubber impact block is fixedly connected to one end of the sliding rod facing the filter cylinder. A connecting frame is fixedly connected to the corresponding end of the sliding rod. The inner wall of the connecting frame is slidably sleeved with the outer wall of the eccentric wheel.

[0008] Preferably, the impact assembly is provided with a cleaning assembly for stirring and cleaning sulfur foam. The cleaning assembly includes a connecting plate fixedly connected to the bottom of the eccentric wheel, a first cleaning scraper fixedly connected to the bottom of the connecting plate, the bottom of the first cleaning scraper being in contact with the surface of the filter cylinder, and two sets of second cleaning scrapers fixedly connected to the outer wall of the drive shaft above the eccentric wheel. The outer wall of the second cleaning scraper is provided with a guide groove, and the bottom of the second cleaning scraper is in contact with the top of the filter cylinder.

[0009] Preferably, the surface of the rubber impact block facing the filter cylinder is arc-shaped, and the outer wall of the rubber impact block is in contact with the inner wall of the filter cylinder.

[0012] Preferably, one side surface of the first cleaning scraper is designed to be inclined, and the inclined surface of the first cleaning scraper is designed to be at a right angle to the bottom of the first cleaning scraper.

[0013] The beneficial effects of this utility model are:

[0014] 1. This utility model uses a motor to drive a transmission shaft to rotate, which in turn drives an eccentric wheel to rotate within a connecting frame. The eccentric wheel then drives two sets of sliding rods on both sides of the connecting frame, causing the two sets of sliding rods to slide back and forth within two sets of fixed seats. This causes two sets of rubber impact blocks to impact the filter cylinder back and forth, and the filter cylinder uses the vibration energy generated by the impact to dislodge sulfur particles attached to the filter pores, thereby restoring the permeability of the filter pores. This enables online cleaning, ensures the continuity of the liquid-solid separation process, and improves the operating efficiency and stability of the device.

[0015] 2. This utility model uses the rotation of the drive shaft to synchronously drive the first cleaning scraper and the second cleaning scraper to rotate. The first cleaning scraper scrapes off the solid sulfur particles accumulated on the filter cylinder, preventing excessive accumulation of solid sulfur particles at the filter holes and thus preventing filter blockage. At the same time, the rotation of the second cleaning scraper can also scrape off the solid sulfur particles accumulated at the top of the filter cylinder and allow the solid sulfur particles to fall into the filter cylinder along the direction of the guide groove, thereby preventing material waste.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-4As shown, a liquid-solid separation device for sulfur foam pretreatment includes a tank 1, a fixing ring is provided on the inner wall of the tank 1, a filter cylinder 2 is placed on the fixing ring, an impact assembly 3 is provided on the top of the tank 1, and the tank 1 is connected to the impact assembly 3 through the filter cylinder 2.

[0025] The impact assembly 3 includes a fixed plate 31 fixedly connected to the top of the tank 1. A motor 32 is bolted to the top of the fixed plate 31. A drive shaft 33 is fixedly connected to the output end of the motor 32. An eccentric wheel 34 is fixedly connected to the bottom of the drive shaft 33. Two sets of fixed seats 35 are symmetrically fixedly connected to the inner walls of the filter cylinders 2 on both sides of the eccentric wheel 34. A slide rod 36 is slidably connected inside the fixed seat 35. A rubber impact block 37 is fixedly connected to one end of the slide rod 36 facing the filter cylinder 2. A connecting frame 38 is fixedly connected to the corresponding end of the slide rod 36. The inner wall of the connecting frame 38 is slidably sleeved with the outer wall of the eccentric wheel 34.

[0026] In practice, the motor 32 drives the transmission shaft 33 to rotate, which in turn drives the eccentric wheel 34 to rotate within the connecting frame 38. The eccentric wheel 34 then drives the two sets of sliding rods 36 on both sides of the connecting frame 38, causing the two sets of sliding rods 36 to slide back and forth within the two sets of fixed seats 35. This causes the two sets of rubber impact blocks 37 to impact the filter cylinder 2 back and forth, and the filter cylinder 2 uses the vibration energy generated by the impact to dislodge the sulfur particles attached to the filter holes, thereby restoring the permeability of the filter holes. This enables online cleaning, ensures the continuity of the liquid-solid separation process, and improves the operating efficiency and stability of the device.

[0027] As a technical optimization of this utility model, the impact component 3 is provided with a cleaning component 4 for stirring and cleaning sulfur foam. The cleaning component 4 includes a connecting plate 41 fixedly connected to the bottom of the eccentric wheel 34. A first cleaning scraper 42 is fixedly connected to the bottom of the connecting plate 41. The bottom of the first cleaning scraper 42 is in contact with the surface of the filter cylinder 2. Two sets of second cleaning scrapers 43 are fixedly connected to the outer wall of the drive shaft 33 above the eccentric wheel 34. A guide groove 44 is opened on the outer wall of the second cleaning scraper 43. The bottom of the second cleaning scraper 43 is in contact with the top of the filter cylinder 2.

[0028] In practice, the rotation of the drive shaft 33 synchronously drives the first cleaning scraper 42 and the second cleaning scraper 43 to rotate. The first cleaning scraper 42 scrapes off the solid sulfur particles accumulated on the filter cylinder 2, preventing excessive accumulation of solid sulfur particles at the filter holes and thus preventing filter blockage. At the same time, the rotation of the second cleaning scraper 43 can also scrape off the solid sulfur particles accumulated at the top of the filter cylinder 2 and make the solid sulfur particles fall into the filter cylinder 2 along the direction of the guide groove 44, thereby preventing material waste.

[0029] As a technical optimization of this utility model, the surface of the rubber impact block 37 facing the filter cylinder 2 is designed with an arc surface, and the outer wall of the rubber impact block 37 is in contact with the inner wall of the filter cylinder 2.

[0030] In practice, the rubber impact block 37 can be fully fitted with the motor 32, thereby ensuring that the impact force output by the rubber impact block 37 to the filter cartridge 2 is evenly transmitted to the filter cartridge 2, thus guaranteeing the unblocking effect of the rubber impact block 37 on the filter cartridge 2.

[0031] As a technical optimization of this utility model, the top of the eccentric wheel 34 is designed with a conical surface, and the right angles on the fixed seat 35 are all designed with chamfers.

[0032] In practice, the solid sulfur particles that fall onto the eccentric wheel 34 or the fixed seat 35 can fall into the filter cylinder 2 along the arc surface of the eccentric wheel 34 and the inclined surface of the fixed seat 35, thereby increasing the yield of liquid after solid-liquid separation.

[0033] As a technical optimization of this utility model, the input end of the motor 32 is electrically connected to the controller via a wire, and the front end of the tank 1 is provided with a groove for storing the controller.

[0034] In practice, this allows staff to operate the motor 32 remotely, while also improving the ease of operation for staff.

[0035] As a technical optimization of this utility model, one side surface of the first cleaning scraper 42 is designed to be inclined, and the inclined surface of the first cleaning scraper 42 is designed to be at a right angle to the bottom of the first cleaning scraper 42.

[0036] In practice, the first cleaning scraper 42 can rotate on the surface of the filter cylinder 2 under the drive of the transmission shaft 33. While rotating, the first cleaning scraper 42 can also drive the solid sulfur particles to move along the inclined surface on the first cleaning scraper 42, and achieve the purpose of turning the solid sulfur particles over, thereby improving the cleaning efficiency of the solid sulfur particles.

[0037] In use, sulfur foam is first poured into the filter cylinder 2, allowing the filter cylinder 2 to filter the sulfur foam. During filtration, solid sulfur particles accumulate on the filter cylinder 2, potentially clogging the filter pores. Then, the motor 32 is operated to rotate the drive shaft 33, which in turn rotates the eccentric wheel 34 within the connecting frame 38. The eccentric wheel 34 then drives two sets of sliding rods 36 on either side of the connecting frame 38, causing the two sets of sliding rods 36 to slide back and forth within two sets of fixed seats 35. This causes two sets of rubber impact blocks 37 to impact the filter cylinder 2, using the vibration energy generated by the impact to dislodge the sulfur particles adhering to the filter pores, thus restoring the permeability of the filter pores. This enables online cleaning, ensuring the continuity of the liquid-solid separation process and improving the operating efficiency and stability of the device.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
