When cleaning impurities in waste animal and plant fats, an impurity cleaning device is required, but the existing cleaning devices still have the following defects:

[0003] (1) The existing cleaning device directly melts the waste animal and vegetable oils and fats when in use, so as to separate the waste animal and vegetable oils and fats from the solid particles. However, only a single-layer filter screen is used during the separation, and the separation effect of the single-layer filter screen is relatively low.

[0004] (2) When the existing cleaning device melts the solidified waste animal and plant fats, the top of the device lacks a seal, which causes the device to melt the waste animal and plant fats at a slow speed.

[0005] (3) When melting waste animal and plant oils, waste gas is generated. Existing cleaning devices lack a step for treating the waste gas and directly discharge it, thereby polluting the environment.

[0006] To this end, an impurity cleaning device for recycling waste animal and vegetable oils is proposed. Summary of the invention

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0029] like Figure 1-5 As shown, this embodiment proposes an impurity cleaning device for recycling waste animal and plant oils, wherein a cleaning mechanism 2 is arranged inside the tank body 1 for rapid melting and multiple filtering of the oils, a sealing component 3 is arranged above the tank body 1 for reducing heat loss inside the tank body 1, and a filtering component 4 is arranged on the sealing component 3 for adsorption and filtration of oil vapor;

[0030] like Figure 4 and Figure 5As shown, the cleaning mechanism 2 includes a first filter 201, a second filter 202, a third filter 203, a placement groove 204, an electromagnetic coil 205 and a heat dissipation hole 206. The first filter 201, the second filter 202 and the third filter 203 are all arranged inside the tank body 1, the placement groove 204 is opened in the wall of the tank body 1, the electromagnetic coil 205 is arranged inside the placement groove 204, the heat dissipation hole 206 is opened on the side wall of the placement groove 204 and is connected to the outside of the tank body 1. The spacing between the first filter 201, the second filter 202 and the third filter 203 is the same. The outer walls of the filter 201, the second filter 202 and the third filter 203 are all in contact with the inner wall of the tank body 1. When in use, the electromagnetic coil 205 is energized, and the temperature inside the tank body 1 can be quickly increased by utilizing the electromagnetic heating principle. Then, the solidified grease to be cleaned is placed inside the tank body 1. At this time, the grease falls on the first filter 201, and then the grease will melt. After melting, the grease will become liquid, and then pass through the first filter 201, the second filter 202 and the third filter 203 in turn. At this time, the grease will be filtered three times, thereby improving the cleanliness of the grease.

[0031] like Figure 4 As shown, the sealing assembly 3 includes a sealing cover 301, a limiting ring 302 and a lifting ring 303. The sealing cover 301 is arranged on the top of the tank body 1, the limiting ring 302 is fixedly connected to the outer wall of the sealing cover 301, the lifting ring 303 is fixedly connected to the top of the sealing cover 301, the inner wall of the limiting ring 302 is tightly fitted with the outer wall of the tank body 1, the sealing cover 301 is coaxial with the tank body 1, and the lifting ring 303 is coaxial with the sealing cover 301. When in use, the lifting ring 303 is connected to an external lifting device, and then the sealing cover 301 is placed above the tank body 1 through the external lifting device, and then lowered. At this time, the sealing cover 301 and the limiting ring 302 descend along the outer wall of the tank body 1 until the bottom of the sealing cover 301 is fitted with the top of the tank body 1, at which time the temperature loss rate inside the tank body 1 can be prevented from accelerating.

[0032] like Figure 4 As shown, the filter assembly 4 includes an air inlet pipe 401, a box body 402 and an exhaust pipe 403. The air inlet pipe 401 is connected and arranged on the top of the sealing cover 301. The box body 402 is fixedly connected to the top of the sealing cover 301. The air inlet pipe 401 is connected and arranged on the side wall of the box body 402 away from the exhaust pipe 403. The top of the air inlet pipe 401 is connected to the interior of the box body 402. The interior of the box body 402 contains a large amount of activated carbon. When the bottom of the sealing cover 301 is fitted with the top of the tank body 1, the interior of the tank body 1 will be in a sealed state. At this time, the grease will melt, and the steam therein will enter the interior of the box body 402 through the air inlet pipe 401. The activated carbon will filter the steam and adsorb harmful substances in the steam. Then the filtered gas will be discharged through the exhaust pipe 403.

[0033] like Figure 5As shown, a butt plate 8 is fixedly connected to the inner wall of the tank body 1, and a connecting rod 9 is fixedly connected to the inside of the second filter screen 202. The top and bottom ends of the connecting rod 9 are fixedly connected to the bottom of the first filter screen 201 and the top of the third filter screen 203 respectively. There are several butt plates 8, which are distributed circumferentially along the central axis of the tank body 1. When in use, the butt plates 8 can provide support for the bottom of the third filter screen 203. The first filter screen 201, the second filter screen 202 and the third filter screen 203 can be connected into a whole through the connecting rod 9, which is convenient for taking out the three filters at one time.

[0034] like Figure 4 As shown, a discharge pipe 5 is provided at the bottom of the tank body 1, and a solenoid valve 6 is provided on the discharge pipe 5. When the grease is melted and filtered, the solenoid valve 6 is opened to discharge the grease to the outside, thereby facilitating the discharge.

[0035] like Figure 4 As shown, a temperature sensor 7 is fixedly connected to the bottom of the sealing cover 301, and the temperature sensor 7 is connected to an external display electrical signal. When in use, the temperature sensor 7 can monitor the internal temperature of the tank body 1 in real time so as to take timely countermeasures.

[0036] The temperature sensor 7 is electrically connected to the electromagnetic coil 205 through the controller, and when a certain temperature is reached, the electromagnetic coil 205 is automatically controlled to disconnect the power supply.

[0037] The interior of the placement groove 204 is filled with a heat-insulating material for protecting the electromagnetic coil 205 and preventing heat loss. The heat-insulating material is thermal insulation cotton.

[0038] like Figure 4 As shown, the first filter 201, the second filter 202 and the third filter 203 are located inside the tank body 1 from top to bottom, and the mesh sizes of the first filter 201, the second filter 202 and the third filter 203 increase successively. When in use, the first filter 201, the second filter 202 and the third filter 203 with increasing mesh sizes can perform multi-stage filtration on the melted grease, thereby further improving the cleaning effect.

[0039] Specifically, when the impurity cleaning device for recycling waste animal and plant oils is used: the electromagnetic coil 205, the temperature sensor and the electromagnetic valve 6 are connected to the external power supply, and then the solidified oil to be cleaned is placed inside the tank body 1, and then the lifting ring 303 is connected to the external lifting equipment, and then the sealing cover 301 is placed on the top of the tank body 1 through the external lifting equipment, and then lowered. At this time, the sealing cover 301 and the limiting ring 302 are lowered along the outer wall of the tank body 1 until the bottom of the sealing cover 301 is in contact with the top of the tank body 1. When the oil falls on the first filter screen 201, the oil will melt, and the steam therein will pass through the air inlet pipe 401 into the box body 402. The activated carbon will filter the steam and adsorb the harmful substances in the steam. Then the filtered gas is discharged through the exhaust pipe 403. After melting, the oil will become liquid, and then After that, it passes through the first filter screen 201, the second filter screen 202 and the third filter screen 203 in turn. Because the mesh numbers of the first filter screen 201, the second filter screen 202 and the third filter screen 203 increase successively, the grease will be filtered three times at this time, and multi-stage filtration can be performed at the same time, thereby improving the cleanliness of the grease, and then the solenoid valve 6 is opened to discharge the grease to the outside, and the filtered solid particles will accumulate on the first filter screen 201, the second filter screen 202 and the third filter screen 203. When there are many impurities on the first filter screen 201, the second filter screen 202 and the third filter screen 203, the first filter screen 201 is directly picked up, and the first filter screen 201, the second filter screen 202 and the third filter screen 203 can be connected into a whole through the connecting rod 9, and then the three filters are taken out at one time, which is convenient for cleaning the first filter screen 201, the second filter screen 202 and the third filter screen 203.

[0040] All technical features in this embodiment can be freely combined according to actual needs.

[0041] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention may also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
