Description

Technical Field

[0001] This invention relates to the field of petroleum processing technology, specifically to a raw material pretreatment device for petroleum processing. Background Technology

[0002] Petroleum, a primary target of geological exploration, is a viscous, dark brown liquid often referred to as the "blood of industry." Petroleum reserves exist in parts of the Earth's upper crust. Its main components are a mixture of various alkanes, cycloalkanes, and aromatic hydrocarbons. There are two main theories regarding the formation mechanism of petroleum: biogenic sedimentary petroleum and petrochemical petroleum. The former, more widely accepted, posits that petroleum is formed from ancient marine or lake organisms through a long evolutionary process, making it a non-renewable resource. The latter theory suggests that petroleum is generated from carbon within the Earth's crust, unrelated to biological processes, and is therefore renewable. Petroleum is primarily used as fuel oil and gasoline, and is also a raw material for many chemical industrial products, such as solvents, fertilizers, pesticides, and plastics.

[0003] According to CN111359491B, a raw material pretreatment device for petroleum processing is disclosed, including a raw material storage tank. The upper end of the raw material storage tank is provided with a tank cover, and the outer wall of the tank is provided with a first feed pipe and support legs. The lower end of the tank is provided with a discharge pipe. The inner wall of the tank is provided with several support rods, and a guide pipe is provided inside the tank. A guide pipe fixing block is provided on the outer wall of the guide pipe. A through hole is formed on the outer wall of the guide pipe, and a groove is formed at the lower end of the guide pipe fixing block. One end of each support rod is engaged in the groove at the lower end of the guide pipe fixing block. This raw material pretreatment device for petroleum processing has a feeding structure, which can uniformly introduce the pretreatment agent directly into the raw material, improving the mixing efficiency of the raw material.

[0004] However, problems still exist. After the raw materials are poured in through the inlet, some of them tend to stick to the inner wall of the tank during the mixing process. Over time, this will affect the mixing efficiency of the raw materials. In addition, a small amount of moisture will still remain in the raw materials after mixing, which will have a certain impact on the yield of finished petroleum products. This needs to be improved to increase the efficiency of petroleum production. Summary of the Invention

[0005] The purpose of this invention is to provide a raw material pretreatment device for petroleum processing to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a raw material pretreatment device for petroleum processing, comprising a pretreatment mechanism and a control mechanism, wherein the control mechanism is disposed on the left side of the surface of the pretreatment mechanism, and the pretreatment mechanism includes a stirring and cleaning unit and an extrusion unit, wherein both the stirring and cleaning unit and the extrusion unit are disposed inside the pretreatment mechanism.

[0007] According to the above technical solution, the stirring and cleaning unit includes a stirring disc, a feed inlet, a guide pipe, a preheating plate, a heating device, a lifting disc, a top cover, a drive motor, a diversion pipe, a heat-conducting pipe, a rotating rod, stirring blades, a sleeve plate, a cleaning plate, and a sleeve rod. Feed inlets are provided on the left and right sides of the surface of the stirring disc. The guide pipe is fixedly connected to the bottom surface of the feed inlet around its perimeter. The diversion pipe is fixedly connected to the inner wall of the guide pipe around its perimeter. The preheating plate is fixedly sleeved around the outer surface of the stirring disc around its perimeter. The heat-conducting pipe is fixedly connected to the inner wall of the preheating plate around its perimeter. The heating device is fixedly installed on both sides of the surface of the preheating plate. The lifting disc is lifted and sleeved around the top surface of the stirring disc. The sleeve rod is fixedly installed at the center of the lifting disc's interior. The sleeve plate is fixedly connected to the outer surface of the sleeve rod around its perimeter. The cleaning plate is fixedly connected to the bottom surface of the sleeve plate. The top cover is fixedly connected to the top surface of the lifting disc. The drive motor is fixedly installed on the top surface of the top cover. The rotating rod is rotatably sleeved around the center of the stirring disc's interior. The stirring blades are fixedly connected to the outer surface of the rotating rod around its perimeter.

[0008] According to the above technical solution, the extrusion unit includes an extrusion box, a hydraulic pump, a pull-out groove, a pull-out handle, a dehydration plate, an extrusion block, a snap-fit ​​ring, and a snap-fit ​​collar. The extrusion box is fixedly installed on the bottom surface of the mixing disc. The hydraulic pump is fixedly installed on the left and right sides of the surface of the extrusion box. The extrusion block is telescopically sleeved on one side of the surface of the hydraulic pump. The snap-fit ​​ring and snap-fit ​​collar are fixedly connected to one side of the surface of the hydraulic pump. The pull-out groove is slidably sleeved on the bottom inner side of the extrusion box. The pull-out handle is fixedly connected to one side of the surface of the pull-out groove. The dehydration plate is fixedly installed on the bottom surface of the extrusion box.

[0009] According to the above technical solution, the control mechanism includes a base, a support rod, and a control panel. The base is fixedly installed on the bottom surface of the control mechanism, the support rod is fixedly installed on the top surface of the base, and the control panel is disposed on the top surface of the support rod.

[0010] According to the above technical solution, the rotating rod and stirring blades are driven by a drive motor that rotates at the center position inside the stirring disc. When the drive motor is started, the rotating rod rotates, which drives the stirring blades to stir the raw materials inside the stirring disc.

[0011] According to the above technical solution, the sleeve plate is sleeved in a corresponding position to the stirring blade, and the cleaning plate moves up and down around the inner wall of the stirring disc through the sleeve plate and the sleeve rod. The surface of the cleaning plate is in contact with the inner wall of the stirring disc as it moves up and down. After the stirring blade has finished stirring the raw material, the operator can lower the lifting disc to the inner wall of the stirring disc by operating the control panel after the sleeve plate is aligned with the stirring blade. The cleaning plate can clean the raw material adhering to the inner wall of the stirring disc, thereby improving the pretreatment effect of the raw material.

[0012] According to the above technical solution, the diameter of the snap-fit ​​collar is smaller than that of the snap-fit ​​ring. The snap-fit ​​collar is telescopically connected to the snap-fit ​​ring via a hydraulic pump. The interior of the extrusion box is correspondingly connected to the interior of the mixing disc. After the raw material is stirred, it falls into the extrusion box. The hydraulic pump is started, and the snap-fit ​​ring and snap-fit ​​collar move towards the center of the extrusion box, which can squeeze out the water and salt mixed in with the raw material. The squeezed water can flow out through the dehydration plate, and the salt can be extracted by the operator through the extraction groove. The operation is convenient and simple, improving the efficiency of raw material pretreatment.

[0013] According to the above technical solution, the heat-conducting pipes are evenly distributed around the outer surface of the stirring disc, and the heat-conducting pipes are connected to the inside of the stirring disc through a preheating plate and a heating device. When the heating device is activated, the surface of the preheating plate is heated, and the heat generated can be transferred to the inner wall of the stirring disc through the heat-conducting pipes to heat the pre-treated raw materials, ensuring that the raw materials do not solidify after being transferred to the inside of the stirring disc, thus ensuring the normal pre-treatment operation of the raw materials.

[0014] According to the above technical solution, the feed inlet and the diversion pipe are both connected to the inside of the mixing disc. The feed inlet can pour the raw materials into the mixing disc. At the same time, when there is too much raw material, it is easy to overflow from the feed inlet. The diversion pipe can reduce the pressure of the feed inlet and ensure that the raw materials are sequentially transferred to the inside of the mixing disc.

[0015] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. By starting the drive motor, the rotating rod rotates, driving the stirring blades to stir the raw materials inside the stirring disc. After the raw materials are stirred, they fall into the extrusion box. The hydraulic pump is started, and the set locking ring and locking collar move to the center of the extrusion box, which can squeeze out the water and salt mixed in the raw materials. The squeezed water can flow out through the dehydration plate, and the salt can be extracted by the operator through the extraction groove. The operation is convenient and simple, improving the efficiency of raw material pretreatment.

[0016] 2. Raw materials can be poured into the mixing disc through the feed inlet. However, when there is too much raw material, it is easy to overflow from the feed inlet. The diversion pipe can reduce the pressure at the feed inlet and ensure that the raw materials are transferred to the mixing disc in sequence.

[0017] 3. By activating the heating device, the surface of the preheating plate is heated. The heat generated can be transferred to the inner wall of the stirring disc through the heat pipe to heat the pre-treated raw materials. This ensures that the raw materials do not solidify after being transferred to the inside of the stirring disc, thus ensuring the normal pre-treatment operation of the raw materials.

[0018] 4. After the raw materials are mixed by the set stirring blades, the operator can lower the lifting disc to the inner wall of the mixing disc by operating the control panel and aligning the sleeve plate with the stirring blades. The set cleaning plate can clean the raw materials adhering to the inner wall of the mixing disc, improving the pretreatment effect of the raw materials. Attached Figure Description
