Description

Technical Field

[0001] This invention relates to the technical field of sludge treatment, and more particularly to a method and equipment for sludge co-firing and pulverizing. Background Technology

[0002] Currently, in order to reduce the amount of sludge stored in coal yards, the method of sludge co-firing is adopted to effectively increase the amount of wet sludge co-firing in coal yards, so that the transferred wet sludge can be co-fired in a timely manner. In order to facilitate the co-firing of sludge, the first thing to do is to crush the sludge.

[0003] Currently, due to the high moisture content and viscosity of sludge, it needs to be dried and pulverized before it can enter the furnace for further co-firing. In related technologies, the dried sludge enters the pulverizing device and is discharged from the outlet. Commonly used crushing methods and equipment for sludge crushing often employ rollers, screws, or toothed mechanisms, which are relatively simple and often ineffective. Some sludge may not be completely pulverized, and directly entering the furnace with this incomplete sludge can lead to incomplete combustion and affect production efficiency. Summary of the Invention

[0009] The sludge is loaded into the conveying system hopper by an excavator and loader. The crushing device is then started, allowing the sludge to fall into the crushing device for crushing.

[0010] After being crushed by the crushing device, the sludge that meets the standards falls from the bottom of the crushing device onto the belt conveyor and enters the next step of co-firing.

[0011] The non-compliant sludge, after being crushed by the crushing device, falls from the lower front side of the crushing device onto the second belt conveyor for secondary recycling and crushing.

[0012] Once the grinding process is complete, turn off the grinding device.

[0038] Example 1

[0039] In the first embodiment of the present invention, a method for sludge co-firing and crushing is provided, which includes the following steps:

[0040] S1. The crushing device is installed below the hopper of the conveying system, and belt conveyor one is installed at the bottom of the crushing device, and belt conveyor two is installed at the front of the lower part of the crushing device.

[0041] Among them, a discharge port 303c is provided at the bottom of the crushing device, and a discharge pipe 303d is provided at the front of the lower part of the crushing device;

[0042] S2. Load the sludge into the conveying system hopper using an excavator and loader, start the crushing device, and let the sludge fall into the crushing device for crushing.

[0043] The upper part of the crushing device is equipped with a crushing tool for crushing and dispersing sludge; the lower part of the crushing device is equipped with a screening tool for screening and separating the crushed sludge, so that sludge of different sizes after crushing is discharged from the discharge port 303c and the discharge pipe 303d respectively.

[0044] S3. The sludge that meets the standards after being crushed by the crushing device falls from the discharge port 303c at the bottom of the crushing device onto the belt conveyor and enters the next step of co-firing.

[0045] S4. The non-compliant sludge after being crushed by the crushing device falls from the discharge pipe 303d at the front of the lower part of the crushing device onto the belt conveyor for secondary recycling and crushing.

[0046] S5. After crushing is complete, turn off the crushing device.

[0047] During operation, the sludge falls from the hopper of the conveying system into the crushing device for crushing and dispersion. After screening and separation, it is discharged from the discharge port 303c and the discharge pipe 303d respectively. The sludge that meets the crushing standard after crushing is conveyed by belt conveyor 1 to enter the next co-firing step. The sludge that does not meet the crushing standard after crushing is conveyed by belt conveyor 2 for recycling. It can be re-conveyed into the hopper of the conveying system for further crushing to ensure that all sludge is completely crushed.

[0048] Example 2

[0049] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6 The second embodiment of the present invention provides a sludge co-firing and crushing device, including an installation unit 100, including an installation cylinder 101, a crushing box 102 connected to the top of the installation cylinder 101, a discharge hopper 103 connected to the bottom of the installation cylinder 101, and a drive assembly 104 installed outside the installation cylinder 101 and the crushing box 102.

[0050] The pulverizing and dispersing unit 200 includes a pulverizing assembly 201 installed inside a pulverizing chamber 102 for pulverizing sludge, and a swirl fan blade 202 installed below the pulverizing assembly 201 for further drying and dispersing the pulverized sludge; and,

[0051] The screening unit 300 includes a guide hopper 301 installed below the cyclone fan blade 202. The bottom of the guide hopper 301 is connected to a screening cylinder 302, and a screening component 303 is installed inside the screening cylinder 302 for screening and distributing sludge. Vibration components 304 are installed at both ends of the screening cylinder 302 for vibrating the screening cylinder 302 to facilitate rapid discharge.

[0052] Furthermore, the pulverizing assembly 201 includes a first pulverizing roller 201a rotatably mounted below the center of the pulverizing box 102, and second pulverizing rollers 201b rotatably connected to the pulverizing box 102 respectively mounted on the upper sides of the first pulverizing roller 201a. Reciprocating moving parts 201c are mounted at both ends of the first pulverizing roller 201a, so that the first pulverizing roller 201a can reciprocate while rotating. Pulverizing teeth 201d are provided on the roller bodies of both the first pulverizing roller 201a and the second pulverizing roller 201b, and the pulverizing teeth 201d on the roller body of the first pulverizing roller 201a and the second pulverizing roller 201b are staggered to improve the sludge pulverizing effect.

[0053] Furthermore, the first crushing roller 201a has symmetrically arranged locking blocks 201a-1 on both sides of the middle part of the roller shaft, and the first crushing roller 201a has symmetrically arranged locking grooves 201a-2 on both sides of the inside of the roller body for matching the locking blocks 201a-1. The cooperation between the locking blocks 201a-1 and the locking grooves 201a-2 allows the first crushing roller 201a to rotate with the roller shaft and move along the roller shaft. Both ends of the roller shaft of the first crushing roller 201a are provided with reciprocating threads.

[0054] The reciprocating moving part 201c includes moving blocks 201c-1 respectively installed on both ends of the first crushing roller 201a. When the roller shaft of the first crushing roller 201a rotates, the moving blocks 201c-1 can reciprocate along the reciprocating thread on the roller shaft, thereby pushing the first crushing roller 201a to reciprocate. This allows the first crushing roller 201a to slide with the two second crushing rollers 201b while rotating, further improving the sludge crushing effect.

[0055] A first protective tube 201c-2 is installed on the outside of the moving block 201c-1 and is rotatably connected to the end of the first crushing roller 201a. A telescopic protective tube 201c-3 is connected to the other end of the first protective tube 201c-2. A second protective tube 201c-4 is rotatably connected to one end of the crushing box 102 on the other end of the telescopic protective tube 201c-3. The first protective tube 201c-2, the telescopic protective tube 201c-3 and the second protective tube 201c-4 can protect the roller shaft of the first crushing roller 201a and prevent sludge from entering the reciprocating thread when the first crushing roller 201a is reciprocating.

[0056] Furthermore, the drive assembly 104 includes gears 104a respectively mounted on the roller shafts of the first crushing roller 201a and the two second crushing rollers 201b. The gears 104a on the roller shaft of the first crushing roller 201a are meshed with the gears 104a on the roller shafts of the two second crushing rollers 201b. A motor 104b is mounted outside the mounting cylinder 101. A rotating shaft 104c is mounted below the motor 104b. The rotating shaft 104c extends into the mounting cylinder 101 and is rotatably connected to the mounting cylinder 101. A first pulley is sleeved on the roller shaft of the first crushing roller 201a and the output shaft of the motor 104b. The two first pulleys are connected by a first belt 104d. A second pulley is sleeved on both the output shaft of the motor 104b and the rotating shaft 104c. The two second pulleys are connected by a second belt 104e.

[0057] Furthermore, a transmission assembly 203 is also installed below the swirl fan blade 202, and the transmission assembly 203 is connected to the drive assembly 104;

[0058] The transmission assembly 203 includes a protective ball cover 203a mounted above the guide hopper 301, a connecting seat 203b connected to the top of the protective ball cover 203a, a connecting rod 203c connected between the connecting seat 203b and the inner walls of both sides of the mounting cylinder 101, and a first bevel gear 203d and a second bevel gear 203e disposed inside the protective ball cover 203a and meshed with it. The output shaft of the motor 104b passes through the protective ball cover 203a and is rotatably connected to the mounting cylinder 101. The first bevel gear 203d is sleeved on the output shaft of the motor 104b. 104c penetrates the protective ball cover 203a and is rotatably connected to the mounting cylinder 101. A rotating ball 202a is provided in the middle of the swirl fan blade 202. Several fan blades are provided around the rotating ball 202a. There are gaps between the fan blades for material leakage. An mounting groove is provided in the connecting seat 203b for the bottom of the rotating ball 202a to be embedded therein. The bottom of the rotating ball 202a is connected to the drive shaft 202b. The drive shaft 202b penetrates the connecting seat 203b and extends into the protective ball cover 203a. The second bevel gear 203e is sleeved on the drive shaft 202b.

[0059] During use, the first crushing roller 201a, the second crushing roller 201b and the swirl fan blade 202 are driven to rotate by the motor 104b. The sludge can be fully crushed by the squeezing and reciprocating pushing of the first crushing roller 201a and the second crushing roller 201b. The crushed sludge comes into contact with the swirl fan blade 202, so that the sludge splashes above the swirl fan blade 202 and comes into contact with the crushing roller again, which improves the crushing and dispersing effect. As the swirl fan blade 202 rotates, the wind generated can have a certain drying effect on the sludge. The sludge that has been further crushed and dispersed will fall into the next step along the gap between the swirl blades.

[0060] Example 3

[0061] Reference Figures 1-6 This is the third embodiment of the present invention, which differs from the second embodiment in that:

[0062] The screening assembly 303 includes screens 303a installed on both sides of the rotating shaft 104c inside the screening cylinder 302. The screens 303a slide in contact with the inner wall of the screening cylinder 302. Arc-shaped plates 303b that fit against the inner wall of the screening cylinder 302 are respectively installed at both ends of the screens 303a. The two arc-shaped plates 303b are arranged symmetrically at the center. A discharge port 303c is opened at the bottom of the screening cylinder 302. A discharge pipe 303d is connected to the lower side of the screening cylinder 302. The discharge pipe 303d is inclined downward to facilitate material discharge. The guide hopper 301 is close to the discharge pipe. A guide plate 301a is provided on one side of 303d, so that only half of the through hole of the guide hopper 301 is connected to the screening cylinder 302, and the arc plate 303b slides in contact with the bottom of the guide plate 301a. When there is a gap between the arc plate 303b and the guide plate 301a, the sludge can slide down along the guide plate 301a onto the screen 303a. When the arc plate 303b contacts the guide plate 301a, the sludge can slide down along the arc plate 303b until it falls onto another arc plate 303b, and is screened as the screen 303a rotates.

[0063] The oscillation assembly 304 includes sliders 304a respectively disposed on the outer rotating shafts 104c at both ends of the screening cylinder 302. Multiple L-shaped rods 304b are installed around the sliders 304a. Vibrating balls 304c are installed at the ends of the L-shaped rods 304b. Reciprocating threads are provided on the shafts 104c at both ends of the screening cylinder 302. As the rotating shafts 104c rotate, the sliders 304a can slide left and right along the reciprocating threads on the rotating shafts 104c, so that the vibrating balls 304c reciprocate and oscillate at both ends of the screening cylinder 302, which facilitates the rapid discharge of sludge.

[0064] During operation, the crushed and dispersed sludge falls into the screening cylinder 302 along the guide hopper 301. At this time, under the transmission action of the second belt 104e, the rotating shaft 104c is driven to rotate by the motor 104b, which drives the screen 303a and the arc plate 303b to rotate. At the same time, the slider 304a can slide back and forth with the rotating shaft 104c, so that the vibrating ball 304c vibrates back and forth on both ends of the screening cylinder 302 to speed up the discharge. When the discharge port 303c is not closed, the crushed sludge that meets the standard can pass through the screen 303a and leak out from the discharge port 303c. When the discharge port 303c is closed and one of the arc plates 303b rotates to the position opposite the discharge pipe 303d, the crushed sludge that does not meet the standard can be discharged from the discharge pipe 303d for recycling.

[0065] The remaining structure is the same as that in Example 2.
