Description

Technical Field

[0001] The invention belongs to the technical field related to centrifuges, and in particular relates to an automatic bottom-discharging centrifuge. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions (e.g., separating cream from milk); they can also be used to remove liquids from wet solids, such as using a washing machine to spin dry wet clothes; special ultra-speed tubular separators can also separate gas mixtures of different densities; some sedimentation centrifuges can also classify solid particles by density or size, taking advantage of the fact that solid particles of different densities or sizes have different sedimentation speeds in liquids.

[0003] The existing automatic bottom-discharging centrifuge technology has the following problems: after the automatic bottom-discharging centrifuge separates the liquid components in the material, the waste residue will continue to fall into the receiving bin. When the viscosity of the waste residue is large, the waste residue is easy to accumulate in the discharge trough and the receiving bin. Therefore, it is necessary to stop the machine frequently and recycle the materials manually, which is very troublesome. In addition, the scraper used in the automatic bottom-discharging centrifuge is a fixed hanging type, which is easy to destroy the vortex formed by the drum, resulting in reduced centrifugal efficiency.

[0016] The automatic bottom-discharging centrifuge of the present invention adds three groups of scrapers on the knife seat, and each group of scrapers and the knife seat are fixed by a spring, so that the material waste residue stuck on the screen is scraped off by the three scrapers, and the scrapers are prevented from scratching the screen. At the same time, the three groups of scrapers can clean the material waste residue on the screen more cleanly, and an air intake pipe is added at the lower end of the centrifuge. The air in the air intake pipe blows the waste residue on the rotating disk and the fixed frame down to prevent the waste residue from accumulating thereon. When using the automatic bottom-discharging centrifuge, first cover the machine barrel, then lock the machine barrel by a lock buckle, and then place the receiving barrel on the right side of the receiving bin.

[0017] Before putting in the material, you need to run the centrifuge idle for a few minutes. This will not only increase the speed of the drum and screen basket, but also allow you to observe the working condition of the centrifuge to see if there are any problems. Then you can put the material into the feed hopper and pour it into the feed hopper manually. Then it will fall into the screen basket through the feed pipe and then disperse onto the screen. The material is separated in the centrifuge by the dual effects of gravity and centrifugal force. When using the cylinder for scraping, the piston rod pushes the knife seat to move downward, and the scraper scrapes the filter cake off the screen. At the same time, there are knife holes on the scraper, which makes it easier for the material to pass through the knife holes, causing less damage to the vortex formed by the drum, and at the same time, the centrifugal efficiency is slightly reduced, which is difficult to affect the overall centrifugal effect. The material waste scraped off by the scraper falls into the receiving bin, and sometimes accumulates on the rotating disk and the fixed frame. In this way, air is blown through the air inlet pipe to blow down the waste residue on the rotating disk and the fixed frame, avoiding the accumulation of waste residue on the rotating disk and the fixed frame, affecting the collection of waste residue, and there is no need for manual cleaning of the screen frequently, which saves a lot of trouble.

[0028] An automatic bottom-discharging centrifuge includes a machine barrel 3 and a base 4. Four brackets 11 are provided. Shockproof pads are provided on the outer walls of the lower ends of the four brackets 11. The centrifuge is prone to generate large vibrations during operation, which is inconvenient to align with the feed hopper 8 and the discharge port 13, and is prone to spilling materials on the ground, making it easy to waste materials. After adding shockproof pads, the shaking of the centrifuge is reduced, so it is easier to put materials into the feed hopper 8, and it will not cause the materials to fall from the discharge port 13 to the ground. An oil suction pump is provided on the outer wall of the left end of the oil suction pipe 5, and the rightmost end of the oil suction pipe 5 is arranged between the machine barrel 3 and the drum 23, so that the oil and water generated after the material is centrifuged can be absorbed by the oil suction pump to prevent accumulation. In the machine barrel 3, it is convenient to collect oil and water. The machine barrel 3 and the machine cover 2 are fixedly connected by a rotating shaft. Buckles are provided on the circumferential outer walls of the machine barrel 3 and the machine cover 2, so that the machine cover 2 can be opened from the machine barrel 3, which is convenient for repairing and replacing the screen 22 and the scraper 31 inside the machine barrel 3. At the same time, it is convenient to clean the screen 22 and the drum 23. When the centrifuge is working, it needs to be locked by the buckle to prevent the machine cover 2 from vibrating easily on the machine barrel 3, so that the scraper 31 causes scratches on the screen 22. An air pipe is provided on the outer wall of the upper end of the cylinder 1, and the transmission motor 10 and the base 4 are fixedly connected by a nut. In this way, compressed air can be introduced into the air pipe to make the piston rod 18 in the cylinder 1 move up and down. , which facilitates the scraper 31 on the left side of the piston rod 18 to scrape off the waste residue contaminated on the screen 22. The interior of the air blowing motor 6 is provided with a machine shaft extending forward, and the interior of the outer cover 15 is provided with fan blades. After the air blowing motor 6 is started, the machine shaft inside the air blowing motor 6 rotates at a high speed, and at the same time drives the fan blades of the outer cover 15, so that air enters the interior of the drum 23 through the air inlet pipe 14, and blows away the waste residue remaining on the screen 22, the rotating disk 28 and the fixing frame 30, so as to avoid the waste residue from accumulating on the rotating disk 28 and the fixing frame 30, which affects the collection of the waste residue.

The screen 22 is a screen hole, so that after the material enters the screen basket 19, the screen basket 19 is driven to rotate by the working motor 7, so that the material can be evenly dispersed on the screen 22 through the screen holes, and then the screen 22 is rotated at a high speed, and the material is separated by centrifugal force, so that the material waste sticks to the screen 22, and the oil and water in the material are sucked away through the oil suction pipe 5. The transmission shaft 25 and the transmission shaft 26 are both provided with an inner part of the shaft hole 27, and the outer part of the transmission shaft 26 is sleeved with a bearing. In this way, the transmission shaft 25 drives the transmission shaft 26 to rotate, so that the rotating shaft 24 inside the gear box 29 also rotates, and at the same time, it will also drive the rotating disk 28 and the drum 23 to rotate at a high speed, which is convenient for separating the materials.

[0029] The working principle and use process of the present invention: After the present invention is installed, when installing the scraper 31, first install the connecting seat 37 on the upper end of the knife seat 35, then install the scraper 31 on the front end of the connecting rod 33, and then install the rear end of the connecting rod 33 in the connecting groove 34 through the spring 36, and then install the other two groups of scrapers 31 on the connecting seat 37 in the same way. At this time, the machine cover 2 can be opened, the inside of the machine cover 2 is facing upward, and then the knife seat 35 is put on the piston rod 18, and then the knife seat 35 is fixed by a nut, and then the connecting box 21 is installed on the left end of the gear box 29, and the connecting box 2 1 is the same height as the gear box 29, and then the rotating shaft 24 inside the gear box 29 is inserted into the lower end of the rotating block 20, and the rotating block 20 is clamped, and then the connecting box 21 and the gear box 29 are installed inside the base 4 through the fixing frame 30, and then the left end of the transmission shaft 26 is installed inside the gear box 29, then one end of the intake pipe 14 can be passed through the receiving bin 12, and then inserted into the fixing hole of the connecting box 21, and the intake pipe 14 is fastened in the fixing hole, and the other end of the intake pipe 14 is installed at the front end of the outer cover 15; when using the automatic bottom unloading centrifuge, first cover the machine cover 2 on the machine barrel 3 Then, the cover 2 is locked by the lock, and the receiving barrel is placed on the lower side of the receiving bin 12. Then, the blowing motor 6, the working motor 7 and the transmission motor 10 are all connected to the external power supply. The model of the blowing motor 6 is Y80, the model of the working motor 7 is Y630, and the model of the transmission motor 10 is Y90. The blowing motor 6, the working motor 7 and the transmission motor 10 are all devices that convert electrical energy into mechanical energy. They use the energized coil to generate a rotating magnetic field and act on the rotor to form a magneto-electrical power rotation torque. The motor is mainly composed of a stator and a rotor. The direction of the force movement of the energized wire in the magnetic field follows the direction of the current. It is related to the direction of the magnetic field. The working principle of the motor is that the magnetic field acts on the force of the current to make the motor rotate, so that the working machine shaft 17 inside the working motor 7 rotates, and the working machine shaft 17 drives the screen basket 19 to rotate; the transmission shaft 25 inside the transmission motor 10 drives the transmission shaft 26 to rotate, and the transmission shaft 26 drives the lower helical gear inside the gear box 29 to rotate, and then the lower helical gear drives the upper helical gear of the gear box 29 to rotate, and the upper helical gear has a rotating shaft 24 inside, and at this time the rotating shaft 24 drives the rotating block 20 and the rotating disk 28 to rotate, and at the same time the rotating disk 28 drives the screen 22 and the drum 23 to rotate;The shaft inside the air blowing motor 6 drives the fan blades to rotate, so that air can be blown into the air inlet pipe 14, and then blown into the inside of the drum 23. Before putting in the material, the centrifuge needs to be idle for a few minutes, which not only increases the speed of the drum 23 and the screen basket 19, but also allows the working condition of the centrifuge to be observed to see if there is any problem. Then the material can be put into the feed hopper 8, and the material is manually poured into the feed hopper 8, and then falls into the screen basket 19 through the feed pipe 9, and then dispersed onto the screen 22. The main working principle of the automatic bottom discharge centrifuge is that the centrifuge drive motor 1 0 drives the centrifuge drum 23 to rotate. When the feeding speed is reached, the material to be separated enters the high-speed rotating drum 23 through the feeding pipe 9. When the feeding reaches the predetermined volume, the feeding is stopped and the separation is started at high speed. Under the action of centrifugal force, the material is filtered through the screen 22. The oil phase passes through the holes of the filter layer drum 23 and is thrown into the cavity and discharged through the oil suction pipe 5. The waste residue phase of the material is trapped in the screen 22 to form a barrel-shaped filter cake. The filter cake can then be washed. After the separation requirement is met, the speed is reduced to the unloading speed state. The scraper 31 automatically moves downward through the cylinder 1 to scrape the filter cake from the inner wall of the screen 22 and pass through the centrifugal The material is discharged from the discharge port 13 at the bottom of the centrifuge. The material is separated by the dual effects of gravity and centrifugal force in the centrifuge. When the cylinder 1 is used for scraping, the working principle of the cylinder 1 is that when compressed air is input from the rodless chamber in the cylinder 1, the rod chamber is exhausted. The pressure difference between the two chambers of the cylinder 1 acts on the piston to form a force that pushes the piston to move, so that the piston rod 18 extends. When the rod chamber is inlet and the rodless chamber is exhausted, the piston rod 18 is retracted. If the rod chamber and the rodless chamber are alternately inlet and exhaust, the piston rod 18 realizes reciprocating linear motion. At this time, the piston rod 18 pushes the knife seat 35 downward together. Move, the scraper 31 scrapes the filter cake on the screen 22, and the scraper 31 has a knife hole 32, so that the material can easily pass through the knife hole 32, which has little damage to the vortex formed by the drum 23, and the centrifugal efficiency is also slightly reduced, which is difficult to affect the overall centrifugal effect. The material waste scraped by the scraper 31 falls into the receiving bin 12, and sometimes accumulates on the rotating disk 28 and the fixed frame 30. In this way, the air in the air inlet pipe 14 blows the waste on the rotating disk 28 and the fixed frame 30 to avoid the waste accumulation on the rotating disk 28 and the fixed frame 30, which affects the collection of the waste. ;
