Description

Technical Field

[0001] The utility model relates to the technical field of cracking oil filtering equipment, in particular to a cracking oil filter. Background Art

[0002] Pyrolysis, also known as pyrolysis, thermal cracking, thermal cracking, high-temperature cracking, refers to the high-temperature cracking reaction of organic matter in the absence of oxygen. It is a chemical process that can convert a sample (mainly high molecular weight compounds) into several other substances (mainly low molecular weight substances). Existing waste tires are usually treated by pyrolysis reaction in order to achieve the purpose of waste tire oil refining and recycling.

[0003] During the cracking process, the liquid oil obtained by cooling the condenser needs to be filtered before entering the storage tank to remove impurities inside the oil. The existing filtering methods mostly directly use filter nets for filtering, but in this filtering method, the debris on the filter net will gradually accumulate, thereby affecting the subsequent filtering effect. Therefore, it is necessary to disassemble and clean it regularly, which is very cumbersome and affects the filtering production efficiency of the cracking oil. Utility Model Content

[0004] Based on the above description, the utility model provides a pyrolysis oil filter to solve the problem that in the existing waste tire recycling equipment, the pyrolysis oil filtering equipment usually uses a filter screen for direct filtration, which not only easily causes the filter screen to be blocked and affects the subsequent filtration efficiency, but also is very cumbersome to clean regularly.

[0005] The utility model is realized through the following technical solutions:

[0006] A pyrolysis oil filter comprises a shell, wherein the top and bottom of the shell are respectively provided with an oil inlet pipe and an oil outlet pipe, and a mounting plate is provided at the inner top of the shell, the mounting plate is hollow inside, the oil inlet pipe extends horizontally and passes through the shell and is inserted into the mounting plate, a screening assembly is also provided inside the shell, wherein a filter cartridge in the screening assembly is arranged at the center of the shell, an oil guide port is arranged on the bottom surface of the mounting plate and is connected with the top of the filter cartridge through a hose, a connecting seat is provided at the bottom of the filter cartridge, the connecting seat is fixedly connected to the inner bottom surface of the shell, a debris discharge pipe is provided at the center of the connecting seat and connects the top end with the bottom end of the filter cartridge, and the bottom end of the debris discharge pipe extends vertically downward to the outside of the shell.

[0007] On the basis of the above technical solution, the present invention can also be improved as follows.

[0008] Furthermore, the screening assembly also includes a buffer member arranged at both ends of the filter cartridge and a vibration motor fixedly installed at the bottom of the filter cartridge, wherein the buffer member is composed of an elastic member and a fixing ring, the elastic member is arranged close to the outer edge of the filter cartridge, the fixing ring has the same outer diameter as the filter cartridge and one side of the fixing ring is fixedly connected to the end of the elastic member, and the other side of the fixing ring is fixedly connected to the bottom surface of the mounting plate and the top surface of the connecting seat.

[0009] Furthermore, the elastic member is an annular air spring or a plurality of damping springs.

[0010] Furthermore, a compartment is provided on the top surface of the filter cartridge, and a plurality of oil delivery holes are arranged around the bottom surface of the compartment. The edge of each oil delivery hole is arranged close to the side wall of the filter cartridge, and the oil delivery hole is connected to the central through hole on the top surface of the compartment through a hose.

[0011] Furthermore, the filter cartridge is arranged in an inverted cone shape as a whole, and a rubber bellows is provided at the top of the discharge pipe. The top of the rubber bellows is connected to the discharge port at the center of the bottom surface of the filter cartridge, and an electronic valve is also provided at the discharge port.

At the same time, a vibration motor is also provided at the bottom of the filter cartridge to effectively drive it to vibrate, forcing a large amount of impurities adhering to the inner wall to slide along the inner wall of the filter cartridge to the bottom for discharge, which can not only improve the filtering and separation efficiency of the oil, but also automatically clean the filtering part without the need to disassemble it, and is very convenient to use.

[0020] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0022] Combination Figure 1-3 As shown, a pyrolysis oil filter comprises:

[0023] The housing 1 is a protective shell of the entire filtering device, and an oil inlet pipe 11 and an oil outlet pipe 12 are respectively provided on the top and bottom thereof;

[0024] The mounting plate 2 is arranged inside the housing 1 and is arranged in a circular shape, and is mainly used for auxiliary support;

[0025] The screening assembly 3 is arranged inside the housing 1 and below the mounting plate 2, and is used for rapid filtering and separation of the pyrolysis oil;

[0026] The connecting seat 4 is arranged on the inner bottom surface of the housing 1 to support and fix the bottom of the screening assembly 3;

[0027] The impurity discharge pipe 5 is arranged at the center of the connecting seat 4 and communicated with the bottom of the screening component 3, and is mainly used to separately discharge the solid impurities inside the screening component 3 for classified recovery.

[0028] Specifically, the interior of the mounting plate 2 is hollow and an oil delivery hole is provided at the center of its bottom surface. The top thereof is connected to the oil inlet pipe 11 on the shell 1, and the inner bottom surface of the mounting plate 2 should be slightly raised upward, so that the oil will automatically diffuse toward the four sides after entering the interior of the mounting plate 2, and thus be transported through the guidance of the oil delivery hole. A plastic hose 21 is provided at the bottom of the oil delivery hole, and the hose 21 should be configured to be corrugated and foldable.

[0029] The screening assembly 3 includes a filter cartridge 31 , a buffer and a vibration motor 34 , wherein the filter cartridge 31 is an inverted cone structure with a plurality of through holes on the top thereof connected one by one with a plurality of hoses 21 , so that the hoses 21 can smoothly guide the oil into the interior of the filter cartridge 31 .

[0030] Since the filter cartridge 31 is an inverted cone structure, the oil can slide down along its inclined inner wall. Even if some residues in the oil block some filter holes, the oil can still precipitate through the filter holes at other positions, thereby ensuring the filtering efficiency.

[0031] At the same time, in order to prevent the oil from flowing directly into the bottom of the filter cylinder 31, a compartment 32 should be set on the top of the filter cylinder 31, and a plurality of oil delivery holes should be set on the bottom of the compartment 32 so that it is close to the side wall of the filter cylinder 31 to ensure that the oil can flow along the inclined side wall of the filter cylinder 31, thereby improving its screening efficiency, and the center of its top surface is connected to the hose 21.

[0032] Two buffers are provided, and are respectively located at the top and bottom of the filter cartridge 31 for connection and fixation, and the buffer consists of an elastic member 33 and a fixing ring. When there is only one elastic member 33, an annular air spring can be used. When multiple elastic members 33 are used, a damping spring is used and arranged around the top and bottom of the filter cartridge 31. According to actual use, other shock-absorbing structures with buffering effects can also be used instead of the above two structures. Figure 2 The schematic diagram shown in FIG. 1 is an elastic member 33 structure composed of a damping spring, and a fixing ring is installed at the other end of the elastic member 33 and fixed to the bottom surface of the mounting plate 2 and the top surface of the connecting seat 4 by bolts.

[0033] The vibration motor 34 is arranged at the bottom of the filter cartridge 31, and its wire extends vertically downward to the outside of the device, or a vibration motor 34 with a battery is directly used.

[0034] Combined with the above structure, when the vibration motor 34 is working, the circulation speed of the oil on the filter cylinder 31 will be accelerated, thereby accelerating the filtering and separation efficiency. At the same time, the impurities separated in the oil will slide downward along the inside of the filter cylinder 31 due to the vibration until they are accumulated at the bottom of the filter cylinder 31, so that the side wall of the filter cylinder 31 always remains unobstructed.

[0035] In order to facilitate the discharge of impurities accumulated at the bottom of the filter cartridge 31, a rubber bellows 51 should be provided at the top of the impurity discharge pipe 5. The pipe is elastic and will not be affected by vibration. The vibration can drive a large amount of residue inside the filter cartridge 31 along the rubber bellows 51 into the impurity discharge pipe 5, and then discharged to the outside of the equipment for centralized treatment.

[0036] The connecting seat 4 should adopt a cylindrical structure, and the outer diameter should be smaller than the outer diameter of the bottom of the filter cartridge 31. The four sides are fixedly connected to the inner wall of the shell 1 through metal support rods. When the oil flows to the bottom of the filter cartridge 31, it will fall directly downward and be discharged along the oil outlet pipe 12 on the shell 1.

[0037] At the same time, in order to prevent the oil from being injected too quickly and part of the oil from being discharged directly into the drainage pipe 5 along the rubber bellows 51, an electronic valve should be installed at the connection between the rubber bellows 51 and the filter cartridge 31. The electronic valve can be controlled by a wire or a remote control structure. If wire control is adopted, its controller should be set on the outer wall of the shell 1.

[0038] An observation window 13 is also provided on the outer side wall of the housing 1 for directly observing the filtering conditions inside.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
