Description

A material uniform humidification device based on high-speed rotating blades Technical Field

[0001] This utility model relates to the field of thermal desorption treatment technology for oily sludge in oil fields, specifically to a material uniform humidification device based on a high-speed rotating blade. Background Technology

[0002] With increasingly stringent environmental protection requirements, the treatment of oily sludge has become a crucial issue for industries such as petroleum and chemical engineering. Thermal desorption technology for oily sludge, as an effective treatment method, can separate the oil from the sludge, enabling resource recycling. However, the resulting dry residue also requires proper subsequent treatment.

[0003] However, the dried residue after thermal desorption is usually quite dry, making it highly susceptible to dust generation during transportation, storage, and further processing. Dust not only pollutes the surrounding environment and harms air quality but can also adversely affect the health of operators, such as causing respiratory illnesses. Therefore, humidifying the dried residue is essential to prevent dust generation.

[0004] Existing material humidification devices have several shortcomings. Some traditional humidification equipment simply sprays water onto the surface of the material, failing to penetrate deep into the material, resulting in uneven humidification and ineffective dust suppression. Other devices use stirring blades, but the mixing effect is poor, making it difficult to break up lumpy materials and achieve thorough mixing of material and water. Furthermore, during operation, materials tend to adhere to the interior of traditional humidification equipment. This not only increases the difficulty and frequency of cleaning but also leads to increased operating resistance, higher energy consumption, and severely impacts humidification efficiency, reducing production continuity and stability. Especially when processing special materials such as thermally desorbed oily sludge, these traditional devices are unable to meet the requirements for efficient and uniform humidification.

[0005] Based on the above background, there is an urgent need to develop a new type of material uniform humidification device to solve the dust problem of thermal desorption sludge of oily sludge, achieve efficient and uniform humidification, and improve environmental benefits and production safety. Summary of the Invention

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A material uniform humidification device based on a high-speed rotating blade includes a feeding device, a material uniform humidification device symmetrically arranged below the feeding device, a water supply device arranged on one side below the material uniform humidification device, and a discharge device arranged on the other side below the material uniform humidification device.

[0008] The uniform material humidification device includes a drive motor, the output shaft of which is fixedly connected to a rotating shaft. Several blade holders are fixedly installed on the outer wall of the rotating shaft. Each blade holder is equidistant along the length of the rotating shaft. Several rotary tillage blades are also fixedly connected to the outer wall of each blade holder by bolts. Each rotary tillage blade is arranged in a ring around the blade holder.

[0009] The bottom surface of the drive motor is fixedly mounted with a support plate, and a material equalization and humidification chamber is fixedly mounted on the top surface of the support plate and on the outside of the rotating shaft. An opening is provided on the top surface of the support plate at the end away from the drive motor.

[0010] An observation hole is provided on one side of the top surface of the uniform material humidification chamber, and an upper water supply pipe is connected through and fixedly connected to the middle of the top surface of the uniform material humidification chamber.

[0011] As a further embodiment of this utility model: several end blocks are fixedly installed at the bottom end of the upper water supply pipe, and several spray pipes are fixedly and connected through the side of each end block, and each spray pipe is L-shaped.

[0012] As a further embodiment of this utility model: a spray head is slidably connected to the upper end of the inner wall of each spray pipe, and multiple spray nozzles with different orientations are opened on the upper end of the outer wall of the spray head. A limit ring is fixedly connected to the lower end of the outer wall of the spray head, and a spring is fixedly connected to the top of the limit ring. The top of the spring is fixedly connected to the inner wall of the spray pipe.

[0013] As a further embodiment of this utility model: the water supply device includes a water tank, and each of the two sides of the top surface of the water tank is fixedly installed with a support plate respectively. A humidifying water pump is fixedly installed in the middle of the top surface of the water tank. The output end of the humidifying water pump is fixedly connected to a lower water supply pipe. The upper end of the lower water supply pipe is connected to and fixedly connected to the upper water supply pipe.

[0014] As a further embodiment of this utility model: the discharge device includes a Y-shaped conveying trough, the top two ends of the Y-shaped conveying trough are respectively fixedly connected to two support plates, and the inner side of the top of the Y-shaped conveying trough is aligned with the opening on the surface of the support plate.

[0015] As a further embodiment of this utility model: the discharge device further includes a chain conveyor, one side of which is aligned with the lower end of the Y-shaped material conveying trough, and the chain conveyor extends in a direction away from the water tank.

[0016] As a further embodiment of this utility model: the hopper is provided, and a quantitative feeder is fixedly connected to both sides of the bottom of the hopper. The bottom of each quantitative feeder is fixedly and connected to a different uniform humidification chamber.

[0017] The beneficial effects of this utility model are:

[0018] (1) By replacing the auger and conveyor belt in the traditional humidifier with multiple sets of high-speed rotating rotary blades, the material conveying components can be powerfully broken up into lumpy materials, making the material particles finer and increasing the contact area between the material and the spray water. At the same time, the blades continuously stir the material during high-speed rotation, allowing the water and material to be fully mixed, which fundamentally solves the problem of uneven humidification and effectively prevents the generation of dust in the subsequent treatment of oily sludge thermal desorption dry residue.

[0019] (2) In addition, the two material humidification devices set in this new invention can be turned on at the same time to carry out humidification work with double efficiency, meet the humidification requirements of materials during large-scale production, and when one of the humidifiers fails, the other can be put into use immediately, ensuring that the material humidification operation is uninterrupted, avoiding production stoppage caused by equipment failure, and effectively ensuring the stability and continuity of the entire production process.

[0020] (3) This utility model uses a humidifying water pump to draw water from the inside of the water tank and deliver the water to the upper water supply pipe. The spray pipe at the end of the upper water supply pipe extends into the uniform material humidification chamber. When water is supplied, the water pressure pushes the spray head in the spray pipe to rise. The water source is sprayed evenly in different directions through the exposed spray nozzles to humidify. When the water supply stops, the spring pulls the spray head to retract into the spray pipe, thereby preventing dust inside the uniform material humidification chamber from clogging the spray nozzles.

[0032] The material leveling and humidifying device 2 includes a drive motor 201. The output shaft of the drive motor 201 is fixedly connected to a rotating shaft 212. Several blade holders 213 are fixedly mounted on the outer wall of the rotating shaft 212. Each blade holder 213 is equidistantly arranged along the length of the rotating shaft 212. Several rotary tillage blades 214 are also fixedly connected to the outer wall of each blade holder 213 by bolts. Each rotary tillage blade 214 is arranged in a ring around the blade holder 213. A support plate 211 is fixedly mounted on the bottom surface of the drive motor 201. A material leveling and humidifying device is fixedly mounted on the top surface of the support plate 211, located outside the rotating shaft 212. The wet chamber 202 has an opening on the top surface of the support plate 211 at the end away from the drive motor 201.

An upper water supply pipe 203 is connected through and fixedly connected to the middle of the top surface of the uniform material humidification chamber 202, as shown in Figure 5. The rotary tillage blades 214 rotate at a high speed of 1200r / min with a blade spacing of 200-250mm. The blades are irregularly twisted, with each set of blades staggered by 45° and having a unique twist angle along the axial direction, so that the material spontaneously moves from the feed end to the discharge end during the mixing process.

[0033] Several end blocks 204 are fixedly installed at the bottom of the upper water supply pipe 203, and several spray pipes 205 are fixed and connected to the side of each end block 204. Each spray pipe 205 is L-shaped, as shown in Figures 2-3. The upper water supply pipe 203 has a total of six lower ports, which are divided into three groups for independent control. The flow rate of a single group is 10L / min, and the number of groups to be opened can be adjusted according to the material humidity requirements.

[0034] Each spray pipe 205 has a spray head 206 slidably connected to the upper end of its inner wall. The upper end of the outer wall of the spray head 206 has multiple spray nozzles 207 facing different directions. The lower end of the outer wall of the spray head 206 is fixedly connected to a limit ring 208. The top of the limit ring 208 is fixedly connected to a spring 209. The top of the spring 209 is fixedly connected to the inner wall of the spray pipe 205, as shown in Figure 4. The spring pushes the limit ring 208 downward, thereby causing the spray head 206 to retract into the spray pipe 205.

[0035] The water supply device 3 includes a water tank 301. The top surface of the water tank 301 is fixedly installed on both sides of each support plate 211. A humidifying water pump 302 is fixedly installed in the middle of the top surface of the water tank 301. The output end of the humidifying water pump 302 is fixedly connected to a lower water supply pipe 303. The upper end of the lower water supply pipe 303 is connected to the upper water supply pipe 203.

[0036] The discharge device 4 includes a Y-shaped conveyor trough 401, the top two ends of which are fixedly connected to two support plates 211, and the inner side of the top of the Y-shaped conveyor trough 401 is aligned with the opening on the surface of the support plate 211. The discharge device 4 also includes a chain conveyor 402, one side of which is aligned with the lower end of the Y-shaped conveyor trough 401, and the chain conveyor 402 extends away from the water tank 301, as shown in Figure 1.

[0037] 1 includes a hopper 101, with a quantitative feeder 102 connected through and fixed to both sides of the bottom of the hopper 101. The bottom of each quantitative feeder 102 is fixed and connected through to different uniform material humidification chambers 202. Both quantitative feeders are equipped with variable frequency motors as drive motors, and the rotation speed of the two quantitative feeders 102 can be freely adjusted, thereby adjusting the feeding speed of the feeding device (range: 0.5-5t / h).

[0038] The working principle of this utility model:

[0039] Before using this material uniform humidification device based on high-speed rotating blades, a comprehensive inspection of the entire device is required to ensure its normal operation. Referring to Figures 1-5, the material to be humidified is initially stored in the hopper 101 of the feeding device 1. When the material in the hopper reaches a certain amount, the left and right quantitative feeders 102 are started according to actual production needs. By adjusting their rotation speeds, the amount of material entering the left and right uniform humidification devices 2 is precisely controlled. After the material enters the uniform humidification device, the high-speed rotating rotary blades 214 powerfully break up any lumpy material. Simultaneously, the spray nozzles 207 begin spraying water. Under the stirring action of the high-speed rotating blades, the material and water are fully mixed, achieving uniform humidification. During this process, the humidifying water pump 302 of the water supply device 3 pressurizes the water in the water tank 301, continuously supplying high-pressure water to the lower water supply pipe 303 and the spray pipe 205. The high-pressure water can also push the spray head 206 upward along the spray pipe 205, thereby exposing the spray nozzle 207 to the external environment and ensuring the smooth progress of the humidification operation. The humidified material is discharged from the openings on the surface of the support plate 211 in each uniform material humidification device 2, collects through the Y-shaped conveyor trough 401, and is then transported to the designated location by the chain conveyor 402, completing the entire material humidification and conveying process.

However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
