[0024] See also Figure 1-3 The utility model provides a technical solution: a crude oil filtering device, comprising a bracket 1, on which a crude oil conveyor belt 2, an oil filter groove, a chute 3, a funnel 4 and an oil collecting box 5 are arranged. The crude oil conveyor belt 2 is used to convey crude oil. The oil filter groove is arranged at the lower side of the end of the crude oil conveyor belt 2 in the running direction. The bottom of the oil filter groove is an oil filter plate. A plurality of filter holes 6 are opened on the oil filter plate. The aperture of the filter hole 6 is smaller than the particle size of the cake residue in the crude oil to be filtered. A push plate 7 is arranged at one end of the oil filter groove close to the crude oil conveyor belt 2. The bottom of the push plate 7 abuts against the upper surface of the oil filter plate. The width of the push plate 7 is greater than the width of the oil filter plate. A driving mechanism is arranged on the push plate 7 to drive the push plate 7 to slide back and forth at both ends of the surface of the oil filter plate. The chute 3 is arranged at one end of the oil filter groove away from the crude oil conveyor belt 2. The funnel 4 is arranged below the oil filter groove for collecting grease flowing out of the filter holes 6. The oil collecting box 5 is arranged below the funnel 4.

[0025] The working process of the utility model is as follows: the crude oil is conveyed to the oil filter tank by the crude oil conveyor belt 2, the crude oil in the oil filter tank flows from the end of the oil filter tank close to the crude oil conveyor belt 2 to the end of the connecting chute 3, the aperture of the filter hole 6 on the oil filter plate at the bottom of the oil filter tank is smaller than the particle size of the cake residue in the crude oil to be filtered, the grease flows into the funnel 4 and the oil collecting box 5 from the filter hole 6, and the cake residue in the crude oil blocks the filter hole 6. At this time, the push plate 7 is pushed to one end of the chute 3 by the driving device, and the bottom edge of the push plate 7 pushes the cake residue on the filter hole 6 to the chute 3 to enter the next process, and then the push plate 7 is pushed back to the original position by the driving device, and so on and so forth, thereby avoiding the problem of blockage of the oil filter plate.

[0026] Specifically, the driving mechanism includes a cylinder 8, a solenoid valve, a timer and a controller. The cylinder 8 is connected between the end of the oil filter tank and the push plate 7. The solenoid valve is connected to the air source pipeline of the cylinder 8 to control the on-off of the air source pipeline and thus control the extension and retraction of the cylinder 8. The solenoid valve, timer and controller are electrically connected. The timer is used to send an electrical signal to the controller when the timing reaches a preset time. The controller is used to control the action of the solenoid valve when receiving the electrical signal sent by the timer. The controller can adopt a PLC controller, so that the driving device drives the push plate 7 to slide back and forth at both ends of the surface of the oil filter plate. When in use, the time of the timer can be set according to the conveying efficiency of the crude oil conveyor belt 2, so as to regularly clean the oil filter plate.

[0027] Furthermore, there are two oil filter tanks: an upper oil filter tank 91 and a lower oil filter tank 92, which are arranged in parallel up and down. There are two corresponding push plates 7, drive mechanisms and slide grooves 3, which are respectively arranged on the upper oil filter tank 91 and the lower oil filter tank 92, and the funnel 4 is arranged below the lower oil filter tank 92.

[0028] Furthermore, when the aperture of the filter hole 6 on the oil filter plate is too small, the crude oil conveyor belt 2 conveys the crude oil to the oil filter tank, and the crude oil in the oil filter tank flows from the end of the oil filter tank close to the crude oil conveyor belt 2 to the end of the connecting chute 3. The cake residue in the crude oil gradually sticks to each other, and the particle size gradually increases. The filter hole 6 of the oil filter plate far away from the crude oil conveyor belt 2 will be blocked quickly, resulting in frequent cleaning and too slow oil filtering; when the aperture of the filter hole 6 on the oil filter plate is too large, the particle size of the cake residue in the crude oil on the oil filter plate close to the crude oil conveyor belt 2 is small, and it is easy to pass through the filter hole 6, resulting in poor filtering effect. The oil filter plate of the upper oil filter tank 91 of the utility model is divided into three sections: the first oil filter plate 911, the second oil filter plate 912, the third oil filter plate 913, the first oil filter plate 911, the second oil filter plate 912, and the third oil filter plate 913 are arranged in sequence along the direction close to or away from the crude oil conveyor belt 2, the aperture of the filter hole 6 on the first oil filter plate 911 is less than the aperture of the filter hole 6 on the second oil filter plate 912, which is less than the aperture of the filter hole 6 on the third oil filter plate 913. The aperture of the filter hole 6 of the first oil filter plate 911 close to the crude oil conveyor belt 2 is small to prevent cake residue in the crude oil from passing through. The aperture of the filter hole 6 of the second oil filter plate 912 and the third oil filter plate 913 away from the crude oil conveyor belt 2 gradually increases. The large-particle cake residue that gradually adheres during the flow of the crude oil will not quickly block the filter hole 6, thereby achieving a good filtering effect.

[0029] Furthermore, the oil filter plate of the lower oil filter tank 92 is divided into three sections: a fourth oil filter plate 921, a fifth oil filter plate 922, and a sixth oil filter plate 923. The fourth oil filter plate 921, the fifth oil filter plate 922, and the sixth oil filter plate 923 are arranged in sequence along the direction close to or away from the crude oil conveyor belt 2. The aperture of the filter hole 6 on the fourth oil filter plate 921 is less than the aperture of the filter hole 6 on the fifth oil filter plate 922, which is less than the aperture of the filter hole 6 on the sixth oil filter plate 923. The principle of the lower oil filter tank 92 is the same as that of the upper oil filter tank 91. The aperture of the filter hole 6 on the sixth oil filter plate 923 is less than the aperture of the filter hole 6 on the first oil filter plate 911. The aperture of the filter hole 6 of the oil filter plate of the lower oil filter tank 92 is smaller, thereby achieving further fine filtration.

[0030] Preferably, the aperture diameter of the filter hole 6 on the first oil filter plate 911 is 4 mm, the aperture diameter of the filter hole 6 on the second oil filter plate 912 is 5 mm, the aperture diameter of the filter hole 6 on the third oil filter plate 913 is 6 mm, the aperture diameter of the filter hole 6 on the fourth oil filter plate 921 is 2 mm, the aperture diameter of the filter hole 6 on the fifth oil filter plate 922 is 3 mm, and the aperture diameter of the filter hole 6 on the sixth oil filter plate 923 is 4 mm.

[0031] Furthermore, a plurality of conveying and filtering holes 22 are provided on the surface of the crude oil conveyor belt 2, and an oil receiving groove 21 is provided directly below the crude oil conveyor belt 2. The oil receiving groove 21 is inclined and the lower end is provided above the lower oil filter groove 92. Preliminary filtering can be performed during the conveying stage, so that the grease flows from the oil receiving groove 21 into the upper oil filter groove 91 or the lower oil filter groove 92, thereby improving the filtering efficiency.

[0032] Specifically, the aperture of the filter hole 6 on the sixth oil filter plate 923 is ≤ the aperture of the delivery filter hole 22 ≤ the aperture of the filter hole 6 on the first oil filter plate 911 , and the lower end of the oil receiving groove 21 is arranged above the lower oil filter groove 92 .

[0033] Furthermore, a cover plate groove 23 is provided above the push plate 7 and the driving mechanism to prevent the grease on the crude oil conveyor belt 2 from flowing into the push plate 7 and the driving mechanism.

[0034] Furthermore, one or both sides of the cover plate groove 23 are inclined above the oil filter plate and / or the oil receiving groove 21, so as to guide the grease on the cover plate groove 23 into the oil filter plate and / or the oil receiving groove 21 for filtering.

[0035] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions.
