Description

Technical Field

[0001] The utility model belongs to the technical field of oil processing equipment, and particularly relates to a light impurity pulverizing and heavy impurity inactivating treatment system for oil processing. Background Technique

[0002] In the oil processing industry, impurities such as pods, straws, stones, lumps of soil, and associated mud mixed in the raw materials of oil processing, such as soybeans or rapeseeds, need to be cleaned out before the oil processing of soybeans or rapeseeds can be carried out. For light impurities such as pods and straws, they generally need to be pulverized, and after pulverization, they can be applied in agriculture and animal husbandry. For heavy impurities such as stones, lumps of soil, and associated mud, they generally need to be inactivated before being discharged into the environment. Discharging after inactivation treatment can reduce their pollution to soil and water sources to meet the environmental protection discharge requirements.

[0003] In the inactivation treatment tank of the existing light impurity pulverizing treatment and heavy impurity inactivating treatment system for oil processing, it generally does not have a guiding conveying component for dispersedly conveying heavy impurities. The heavy impurities are centrally conveyed into the tank body of the inactivation treatment tank and then steam inactivation treatment is carried out. It is difficult for the heavy impurities to come into full contact with the steam, and it is easy to have uneven local heating, resulting in poor inactivation treatment effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a light impurity pulverizing and heavy impurity inactivating treatment system for oil processing to solve the above problems, aiming to solve the technical problems that in the inactivation treatment tank of the existing light impurity pulverizing treatment and heavy impurity inactivating treatment system for oil processing, it generally does not have a guiding conveying component for dispersedly conveying heavy impurities. The heavy impurities are centrally conveyed into the tank body of the inactivation treatment tank and then steam inactivation treatment is carried out. It is difficult for the heavy impurities to come into full contact with the steam, and it is easy to have uneven local heating, resulting in poor inactivation treatment effect.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A light impurity pulverizing and heavy impurity inactivating treatment system for oil processing includes an impurity feed bin, a screw conveyor arranged at the discharge port of the impurity feed bin, a light impurity pulverizing component and a heavy impurity inactivating component connected to the screw conveyor;

[0007] The heavy impurity inactivating component includes an inactivation tank, a plurality of steam dispersion pipes distributed inside the inactivation tank, a steam input pipe connected to the steam dispersion pipes for steam input, a guiding conveying component arranged inside the inactivation tank for receiving heavy impurities and guiding and conveying the heavy impurities in the direction close to the steam dispersion pipes, and a material stirring component for dispersing heavy impurities. A plurality of steam dispersion holes are opened on the steam dispersion pipes from top to bottom.

[0008] As a further optimized solution of the utility model, the heavy impurity inactivation assembly further includes a heavy impurity conveying pipeline connected to the bottom of the output end of the screw conveyor and the top of the inactivation tank, and a heavy hammer valve arranged on the heavy impurity conveying pipeline.

[0009] As a further optimized solution of the utility model, a protective net frame is arranged outside each steam dispersion pipeline inside the inactivation tank. The guiding and conveying assembly includes a dispersion conveying member arranged at the inner top of the inactivation tank and below the heavy impurity conveying pipeline, and a receiving tray arranged between the protective net frames and below the dispersion conveying member for receiving the heavy impurities conveyed out by the dispersion conveying member. A falling channel is left between the receiving tray and the inner wall of the inactivation tank;

[0010] The middle part of the dispersion conveying member is a concave cylinder, and the outside is a cover body inclined downward. The receiving tray is funnel-shaped;

[0011] A plurality of guiding outlets are opened on the side wall of the cylinder body. The outlet end of each guiding outlet is connected with a guiding frame plate, and the discharge outlet of the guiding frame plate is aligned with the steam dispersion pipeline one by one and is located above the receiving tray.

[0012] As a further optimized solution of the utility model, the material stirring and mixing assembly includes a rotating shaft rotatably connected inside the inactivation tank and rotatably connected with the dispersion conveying member and the receiving tray, a servo motor arranged inside the bottom wall of the cylinder body for driving the rotating shaft to rotate, a plurality of material stirring rods arranged on the rotating shaft and between the cover body and the receiving tray, and a plurality of dispersion rods arranged on the rotating shaft and below the receiving tray.

[0013] As a further optimized solution of the utility model, a discharge pipe is arranged at the bottom of the inactivation tank, and a discharge valve is arranged on the discharge pipe.

[0014] As a further optimized solution of the utility model, the light impurity crushing assembly includes a light impurity conveying pipeline arranged at the top of the output end of the screw conveyor, a crusher connected to the output end of the light impurity conveying pipeline, a spiral dust collector connected to the dust output end of the crusher, and a fan connected to the gas output end of the spiral dust collector.

[0015] As a further optimized solution of the utility model, a cleaning port is opened on the inactivation tank, and a sealing door is detachably connected to the cleaning port.

[0016] The beneficial effects of the utility model are as follows:

[0017] 1) The utility model classifies and processes light impurities and heavy impurities through a light impurity pulverizing component and a heavy impurity inactivating component. By uniformly arranging a number of steam dispersion pipes inside the inactivation tank and opening a number of steam dispersion holes on the steam dispersion pipes, high-temperature steam can be evenly dispersed inside the inactivation tank. Through the guiding and conveying component, the heavy impurities are dispersed and conveyed close to each steam dispersion pipe so that they can fully contact the high-temperature steam, and the heavy impurities are better inactivated by the high-temperature steam to meet the environmental protection emission requirements;

[0018] 2) The utility model uses the cylinder body of the dispersion conveying part to receive the heavy impurities falling into the inactivation tank. Through the guiding outlet, the guiding frame plate, and the cover body of the dispersion conveying part, the heavy impurities are conveyed towards the direction close to the steam dispersion pipe, so that the heavy impurities contact the relatively high-temperature steam to achieve a better high-temperature inactivation effect. Subsequently, the heavy impurities fall on the top of the receiving tray. The receiving tray is funnel-shaped. Combining with the stirring and dispersing effect generated by the rotation of the stirring rod, the heavy impurities on the top of the receiving tray are loosened and dispersed. Before a small amount of heavy impurities are mixed with a large amount of heavy impurities at the bottom of the inactivation tank, they can better contact the high-temperature steam, thereby achieving a better high-temperature inactivation effect.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present application will be further described in detail below in conjunction with the accompanying drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0026] As Figures 1-5 shown, a light impurity crushing and heavy impurity inactivation treatment system for oil processing includes an impurity bin 1, a screw conveyor 2 provided at the discharge port of the impurity bin 1, a light impurity crushing assembly and a heavy impurity inactivation assembly connected to the screw conveyor 2;

[0027] The heavy impurity inactivation assembly includes an inactivation tank 6, a plurality of steam dispersion pipes 8 distributed inside the inactivation tank 6, a steam input pipe 7 connected to the steam dispersion pipes 8 for steam input, a guiding and conveying assembly provided inside the inactivation tank 6 for receiving heavy impurities and guiding and conveying the heavy impurities in the direction close to the steam dispersion pipes 8, and a material stirring and distributing assembly for dispersing the heavy impurities. A plurality of steam dispersion holes 81 are opened on the steam dispersion pipes 8 from top to bottom.

[0028] It should be noted that the number of the steam dispersion pipes 8 can be at least three. When there are three, the three steam dispersion pipes 8 are evenly distributed in the inactivation tank 6 at equal intervals, and an angle of 120 degrees is formed between two adjacent steam dispersion pipes 8. When there are four, the four steam dispersion pipes 8 are also evenly distributed in the inactivation tank 6 at equal intervals, and an angle of 90 degrees is formed between two adjacent steam dispersion pipes 8;

[0029] In this embodiment, the guiding outlet 13 and the guiding frame plate 14 correspond to the steam dispersion pipes 8 one by one.

[0030] Preferably, the heavy impurity inactivation assembly further includes a heavy impurity conveying pipe 4 connected to the bottom of the output end of the screw conveyor 2 and the top of the inactivation tank 6, and a heavy hammer valve 5 provided on the heavy impurity conveying pipe 4.

[0031] Preferably, a protective net frame 11 is provided outside each steam dispersion pipe 8 inside the inactivation tank 6. The guiding and conveying assembly includes a dispersion and conveying member 12 provided at the inner top of the inactivation tank 6 and below the heavy impurity conveying pipe 4, and a receiving tray 15 provided between the protective net frames 11 and below the dispersion and conveying member 12 for receiving the heavy impurities conveyed out by the dispersion and conveying member 12. A falling channel is left between the receiving tray 15 and the inner wall of the inactivation tank 6;

[0032] The middle part of the dispersion and conveying member 12 is a concave cylinder, and the outer part is an inclined downward cover. The receiving tray 15 is in a funnel shape;

[0033] A plurality of guiding outlets 13 are formed in the side wall of the cylinder body, and a guiding frame plate 14 is connected to the outlet end of each guiding outlet 13. The material outlet of the guiding frame plate 14 is aligned with the steam dispersion pipeline 8 one by one and is located above the material receiving tray 15.

[0034] It should be noted that in this embodiment, the cylinder body of the dispersion conveyor 12 is protected under the heavy impurity conveying pipeline 4, and the cover body of the dispersion conveyor 12 plays a role of shielding. When stirring, it can also reduce the entry of dust into the heavy impurity conveying pipeline 4 and reduce the blockage of the heavy impurity conveying pipeline 4.

[0035] Preferably, the material stirring and dispersing assembly includes a rotating shaft 16 rotatably connected inside the inactivation tank 6 and rotatably connected to the dispersion conveyor 12 and the material receiving tray 15, a servo motor 17 arranged inside the bottom wall of the cylinder body and used to drive the rotating shaft 16 to rotate, a plurality of material stirring rods 18 arranged on the rotating shaft 16 and located between the cover body and the material receiving tray 15, and a plurality of dispersion rods 19 arranged on the rotating shaft 16 and located below the material receiving tray 15.

[0036] In this embodiment, the servo motor 17 works to drive the rotating shaft 16, the material stirring rods 18 and the dispersion rods 19 to rotate together. The material stirring rods 18 rotate to stir and disperse the heavy impurities on the top of the material receiving tray 15, and the dispersion rods 19 rotate to stir, disperse and turn over the heavy impurities falling on the bottom of the inactivation tank 6.

[0037] Preferably, a discharge pipe 9 is arranged at the bottom of the inactivation tank 6, and a discharge valve 10 is arranged on the discharge pipe 9.

[0038] In this application, the impurity bin 1 is used to store the mixture of light impurities and heavy impurities in the mixed impurities. The light impurities are such as straws, pods, etc.; the heavy impurities are such as stones, lumps of soil, side-by-side mud and other organic impurities with a large specific gravity. The mixed impurities are conveyed into the screw conveyor 2. The screw conveyor 2 works to convey the mixed impurities. Then, the light impurities will be conveyed into the light impurity crushing assembly by the action of wind or suction. The heavy impurities will still remain at the bottom of the screw conveyor 2 under the action of gravity. Then, when the heavy hammer valve 5 is opened, the heavy impurities will fall into the heavy impurity conveying pipeline 4 and be conveyed to the inside of the inactivation tank 6 through the heavy impurity conveying pipeline 4;

[0039] The heavy impurities falling into the inactivation tank 6 will fall into the cylinder of the dispersion conveying member 12 and be transported downward through the guide outlet 13, the guide frame plate 14 and the cover of the dispersion conveying member 12. The heavy impurities are first transported toward the direction close to the steam dispersion pipe 8 through the guide frame plate 14, and then the heavy impurities will fall on the top of the receiving tray 15. The steam input pipe 7 and the steam dispersion pipe 8 are used to input high-temperature steam, and then the high-temperature steam will be continuously transported from the steam dispersion pipe 8 through the steam dispersion hole 81 and diffused in the inactivation tank 6. Generally, the steam temperature near the steam dispersion pipe 8 will be higher, and the steam temperature at the center of the inactivation tank 6 will be higher. The temperature will be lower, and the heavy impurities are first transported toward the direction close to the steam dispersion pipe 8, the purpose of which is to allow the heavy impurities to contact with the higher temperature steam to achieve a better high-temperature inactivation effect, and then the heavy impurities will fall on the top of the receiving tray 15, and the receiving tray 15 is funnel-shaped, so that the heavy impurities can stay on the top of the receiving tray 15 for a longer period of time. Under the stirring and dispersing action of the material-moving rod 18, the heavy impurities on the top of the receiving tray 15 are also relatively loose and dispersed. A small amount of heavy impurities can better contact with the high-temperature steam before mixing with a large amount of heavy impurities at the bottom of the inactivation tank 6, thereby achieving a better high-temperature inactivation effect;

[0040] Under the stirring and dispersing action of the material shifting rod 18, the heavy impurities falling from the falling channel between the receiving plate 15 and the inner wall of the inactivation tank 6 will fall to the bottom of the inactivation tank 6. Through the stirring action of the dispersing rod 19, the heavy impurities are constantly turned over, and can be better contacted with the high-temperature steam, thereby achieving a better high-temperature inactivation effect. After the heavy impurities are inactivated, the discharge valve 10 can be opened, and then the inactivated heavy impurities can be transported out of the inactivation tank 6 through the discharge pipe 9. The heavy impurities lose their biological activity after inactivation to prevent the spread of genes and microorganisms.

[0041] Preferably, the light impurity crushing component includes a light impurity conveying pipeline 3 arranged at the top of the output end of the screw conveyor 2, a crusher 20 connected to the output end of the light impurity conveying pipeline 3, a spiral dust collector 21 connected to the dust output end of the crusher 20, and a fan 22 connected to the gas output end of the spiral dust collector 21. Light impurities such as straw, bean pods, etc. will be sucked into the light impurity conveying pipeline 3 through the wind force generated by the operation of the fan 22, and then transported to the crusher 20 through the light impurity conveying pipeline 3 for crushing. The dust and dirt generated during the crushing process will be filtered and separated by the spiral dust collector 21. Among them, the crusher 20, the spiral dust collector 21, the fan 22 and their combined use are all conventional technical means in the prior art and will not be repeated here.

[0042] Preferably, a cleaning port is provided on the inactivation tank 6 , and a sealing door is detachably connected to the cleaning port, so as to facilitate cleaning of the inside of the inactivation tank 6 .

[0043] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several variations and improvements can still be made, and these all fall within the protection scope of the present utility model.
