a transmission part 23 connected with the anti-blocking assembly 22, wherein the transmission part 23 comprises a shell 231; and a plurality of gear teeth 232 which are positioned on the inner ring of the shell 231 and meshed with the second transmission gear 224, and are used for driving the threaded pipe 223 to rotate, so as to drive the scraper 221 to do linear motion, the surface of the shell 231 is further provided with a guide rail 233, and the end surface of the threaded pipe 223 is slidably connected in the guide rail 233.
In the above scheme, the heat source may be a molten salt, and the molten salt is a molten mass formed after the salt is melted, such as a molten mass of a halide, a nitrate, or a sulfate of an alkali metal or an alkaline earth metal. The molten salt is a molten body formed by metal cations and non-metal anions, and aims to heat waste mineral oil, particularly liquid with higher viscosity such as camera oil, and the fluidity of the waste mineral oil can be increased after the waste mineral oil is heated, and the diluting bin 12 is used for diluting the waste mineral oil with higher viscosity by using an organic solvent, further increasing the fluidity of the waste mineral oil and filtering and removing impurities of the waste mineral oil; the conventional technical means in the prior art are omitted for brevity.
The principle of impurity removal: the driving mechanism 3 includes a driving motor 31, a driving gear 32 and a transmission chain 33, the driving motor 31 is connected to the driving gear 32 through a driving shaft, the transmission chain 33 is engaged and connected between the driving gear 32 and the first transmission gear 212, and is used for driving the centrifugal cylinder 21 to rotate at a high speed, under the driving of centrifugal force, the waste mineral oil and the small particle dust can enter the filter bin 13 through the filter hole 211, and then continuously enter the integrated filter mechanism 5 for further filtering treatment, and the large particle impurities such as iron filings and residues in the waste mineral oil can be blocked in the centrifugal cylinder 21, so that the function of filtering and removing impurities by using the centrifugal principle is realized.
Anti-blocking principle of anti-blocking component 22: because the anti-blocking assembly 22 is installed on the centrifuge tube 21, it will follow the centrifuge tube 21 to make high-speed circular motion, when the second transmission gear 224 in the anti-blocking assembly 22 rotates around the central axis of the centrifuge tube 21 (referred to as revolution here), the second transmission gear 224 will also engage with several gear teeth 232 on the transmission part 23, because the transmission part 23 is stationary, the second transmission gear 224 and the threaded pipe 223 will also make rotational motion around their own axis (referred to as rotation here), the rotating threaded pipe 223 will drive the threaded rod 222 and the scraping plate 221 to make linear motion along the inner wall of the centrifuge tube 21, thereby cleaning up the impurities adhered to the inner wall of the centrifuge tube 21, and making the waste mineral oil discharge from the filter hole 211 smoothly, and having the characteristics of good anti-blocking performance and high working efficiency.
In the above scheme, the scraping plate 221 is further connected to the top cover 214 on the centrifugal cylinder 21 through a limiting rod, so as to ensure that the scraping plate 221 and the threaded rod 222 do linear motion, because the limiting rod is more common in the prior art (screw rod transmission principle), and is not shown in the drawing, it should be noted that the number of the gear teeth 232 is not a fixed value, because the length of the threaded pipe 223, the modulus of the second transmission gear 224, and the rotation speed of the centrifugal cylinder 21 need to be considered, the larger the number of the gear teeth 232 is, the larger the distance that the centrifugal cylinder 21 rotates for one circle to drive the scraping plate 221 to move is, thus the limit distance of the threaded pipe 223 is easily reached, the problem of wire sliding between the threaded pipe 223 and the threaded rod 222 is easily caused, the steering of the driving motor 31 needs to be adjusted for many times, the labor is more wasted, the working efficiency is reduced, the number of the gear teeth 232 is designed as small as possible, and the purpose is to achieve the effect that the scraping plate 221 moves from one end of the centrifugal cylinder 21 to the other end after the centrifugal cylinder 21 rotates for several circles, so that the steering of the driving motor 31 does not need to be adjusted for many times, and the steering is provided with convenient use and high working efficiency.
Referring to fig. 1, 8, 9 and 10, as an embodiment of the present application, an electromagnet 17 and a fixing portion 18 are fixedly connected in the filter bin 13, a terminal 171 electrically connected to the control box 6 is disposed on the electromagnet 17, the fixing portion 18 is designed as a fixing ring, the fixing ring is sleeved on the outer side of the transmission portion 23, a limiting groove 181 is disposed on an inner wall of the fixing ring along an axis direction of the fixing ring, a first limiting block 235 extending along the axis direction is disposed on an outer wall of the housing 231, the first limiting block 235 is slidably connected in the limiting groove 181, a magnet block 236 is disposed on one side of the housing 231 close to the electromagnet 17, a length of the limiting groove 181 is smaller than a height of the fixing ring, and the electromagnet 17 achieves a purpose of driving the housing 231 to move toward or away from the second transmission gear 224 by absorbing the magnet block 236.
In the above scheme, the electromagnet 17 is arranged to facilitate the user to control the frequency of use of the anti-blocking assembly 22 and to facilitate the user to select when to use the anti-blocking assembly 22, and the electromagnet 17 controls the working principle of the movement of the anti-blocking assembly 22: when the control box 6 powers on the electromagnet 17, the magnetism of the electromagnet 17 is opposite to the magnetism of the magnet block 236 on the casing 231 of the transmission part 23, and the opposite attraction is used to move away, so that the casing 231 can be driven to move towards the direction close to the electromagnet 17, meanwhile, the gear teeth 232 on the casing 231 move towards the direction away from the second transmission gear 224, when the electromagnet 17 is attached to the magnet block 236, the gear teeth 232 just leave the second transmission gear 224 completely, so that when the second transmission gear 224 in the anti-blocking assembly 22 rotates (revolves) along with the centrifugal cylinder 21, the second transmission gear 224 does not rotate, and the anti-blocking assembly is generally suitable for the situation that the waste mineral oil just starts to enter the centrifugal cylinder 21 or the situation that the impurities in the waste mineral oil are few, and when the control box 6 powers off the electromagnet 17, the block 236 automatically resets under the action of its own gravity after losing the adsorption force of the electromagnet 17, and the gear teeth 232 and the second transmission gear 224 are re-meshed at this time, and is generally suitable for the situation that the impurities in the waste mineral oil or after the magnet cylinder 21 is used for a period of time, and has strong practicability.
