[0001] This utility model belongs to the field of crude oil heating technology, specifically relating to a crude oil heating pretreatment device. Background Technology

[0002] Traditional crude oil heating pretreatment equipment does not take into account the impurities that freshly extracted oil contains during the heating process. Heating is performed without filtering these impurities, which negatively impacts heating efficiency. The prior art CN221122517U discloses a skid-mounted crude oil heating pretreatment device, including a support plate. A heating mechanism is fixedly connected to the upper end of the support plate. A discharge component is fixedly connected to the right side of the heating mechanism, and an inlet pipe is fixedly connected to the left side of the heating mechanism. A flange is fixedly connected to the left end of the inlet pipe, and a connecting pipe is fixedly connected to the left end of the flange. An oil inlet pipe is fixedly connected to the upper end of the connecting pipe. Four square grooves are opened at the upper end of the oil inlet pipe, and filter elements are slidably connected to the inner surfaces of the four square grooves. Through the cooperation of the filter elements, heating mechanism, and heat transfer components, the crude oil can be filtered before heating pretreatment, removing impurities contained in the crude oil, reducing heat loss caused by impurities, effectively improving the heating efficiency of the device, and enhancing the practicality of the device.

[0003] However, after prolonged use, a large amount of impurities from the crude oil accumulate on the filter screen in the existing equipment. Furthermore, when the oil inlet pipe is connected to the crude oil pipeline for oil intake, it is difficult for operators to disassemble the oil inlet pipe to clean the filter screen, which can easily lead to clogging of the filter screen. Utility Model Content

[0004] The purpose of this invention is to provide a crude oil heating pretreatment device to solve the problem that in existing devices, after long-term use, a large amount of impurities in the crude oil accumulate on the filter screen, and when the oil inlet pipe is connected to the crude oil pipeline for oil intake, it is difficult for operators to disassemble the oil inlet pipe to clean the filter screen, which easily leads to filter screen blockage.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: It includes a device body and an oil inlet pipe, wherein the oil inlet pipe is disposed on the device body. It also includes filtering components; The filter assembly includes a filter screen, a fixed cylinder, a movable frame, a movable rod, a cleaning scraper, a discharge frame, a connecting rod, a rubber block, a storage rack, and a collection component. The filter screen is fixedly connected to the oil inlet pipe and located on one side of the oil inlet pipe. The fixed cylinder is connected to the oil inlet pipe. The movable frame is slidably connected to the fixed cylinder and located on one side of the fixed cylinder. The movable rod is fixedly connected to the movable frame and located on one side of the movable frame. The cleaning scraper is fixedly connected to the movable rod and located on the side of the movable rod closer to the filter screen. The discharge frame is connected to the oil inlet pipe and located on the side of the oil inlet pipe away from the fixed cylinder. The connecting rod is fixedly connected to the cleaning scraper and located on one side of the cleaning scraper. The rubber block is fixedly connected to the connecting rod and located on the side of the connecting rod closer to the oil inlet pipe. The storage rack is connected to the discharge frame and located on one side of the discharge frame. The collection component is disposed on the oil inlet pipe.

[0006] The collection component includes a collection rack and a collection box. The collection rack is fixedly connected to the oil inlet pipe and is located on one side of the oil inlet pipe.

[0007] The filter assembly further includes a rubber stopper, which is fixedly connected to the movable frame and located on the side of the movable frame closer to the fixed cylinder.

[0008] The filter assembly also includes a locking bolt, which is disposed on the fixed cylinder and abuts against the movable frame.

[0009] The filter assembly further includes a side plate, which is fixedly connected to the cleaning scraper and located on one side of the cleaning scraper.

[0010] This utility model discloses a crude oil heating pretreatment device. When the filter screen in the inlet pipe of the crude oil pipeline needs to be cleaned, the operator moves the moving frame, which in turn moves the cleaning scraper on the moving rod to move the upper surface of the filter screen. This scrapes and cleans large impurities on the upper surface of the filter screen and pushes them towards the outlet frame. At this time, the movement of the cleaning scraper moves the rubber block on the connecting rod into the receiving frame, thereby opening the outlet frame. The cleaned impurities can then be discharged through the outlet of the outlet frame. Thus, the cleaning of impurities on the filter screen by the cleaning scraper and the discharge of impurities by the outlet frame prevent a large accumulation of impurities in the crude oil on the filter screen, which could cause blockage.

[0018] This utility model provides a crude oil heating pretreatment device, including a device body 101, an oil inlet pipe 102, and a filter assembly. The filter assembly includes a filter screen 103, a fixed cylinder 104, a movable frame 105, a movable rod 106, a cleaning scraper 107, an outlet frame 108, a connecting rod 109, a rubber block 110, a storage rack 111, a collection component, a rubber plug 112, a locking bolt 113, and a side plate 114. The collection component includes a collection rack 115 and a collection box 116. This solution addresses the problem in existing devices where, after prolonged use, a large amount of impurities accumulate on the filter screen, and when the oil inlet pipe is connected to the crude oil pipeline, it is difficult for operators to disassemble the oil inlet pipe to clean the filter screen, easily leading to filter clogging. It is understood that this solution can be used in situations where easy cleaning of the filter screen is required.

[0019] In this embodiment, the oil inlet pipe 102 is connected to the device body 101. Crude oil can be introduced through the oil inlet pipe 102 and the introduced crude oil can be preheated through the device body 101. The structure of the device body 101 is described in detail in the prior art CN221122517U, and will not be repeated here.

[0020] The filter screen 103 is fixedly connected to the oil inlet pipe 102 and located on one side of the oil inlet pipe 102. The fixed cylinder 104 is connected to the oil inlet pipe 102. The movable frame 105 is slidably connected to the fixed cylinder 104 and located on one side of the fixed cylinder 104. The movable rod 106 is fixedly connected to the movable frame 105 and located on one side of the movable frame 105. The cleaning scraper 107 is fixedly connected to the movable rod 106 and located on the side of the movable rod 106 closer to the filter screen 103. The outlet frame 108 is connected to the oil inlet pipe 102 and located on the side of the oil inlet pipe 102 away from the fixed cylinder 104. Rod 109 is fixedly connected to the cleaning scraper 107 and located on one side of the cleaning scraper 107. Rubber block 110 is fixedly connected to the connecting rod 109 and located on the side of the connecting rod 109 near the oil inlet pipe 102. Collection rack 111 is connected to the outlet rack 108 and located on one side of the outlet rack 108. The collecting component is disposed on the oil inlet pipe 102. Filter screen 103 is bolted and fixedly installed in the oil inlet pipe 102. The filter screen 103 can filter impurities in the introduced crude oil. Fixed cylinder 104 is welded to the oil inlet pipe 102. Movable frame 105 is slidably connected to the fixed cylinder 104. The movable rod 106 is welded to the movable frame 105, and the cleaning scraper 107 is welded to the movable rod 106. The operator moves the movable frame 105, thereby moving the cleaning scraper 107 on the movable rod 106 to the upper surface of the filter screen 103. The guide frame 108 is connected to the oil inlet pipe 102, allowing large impurities on the upper surface of the filter screen 103 to be scraped, cleaned, and pushed towards the guide frame 108. The cleaned impurities are then discharged through the outlet of the guide frame 108. The connecting rod 109 is welded to the cleaning scraper 107, and the rubber block 110 is adhered to the connecting rod 109. The rubber block 110 can block the outlet frame 108, preventing crude oil from being discharged from the outlet frame 108 when oil is introduced into the oil inlet pipe 102. Simultaneously, the connecting rod 109 allows it to move with the cleaning scraper 107. The storage frame 111 is connected to the outlet frame 108 and can store the moved rubber block 110. The collection component is installed on the oil inlet pipe 102, allowing for the centralized collection of discharged impurities, facilitating processing by operators. This enables the cleaning of the filter screen 103 in the oil inlet pipe 102, which needs to enter the crude oil pipeline.The operator moves the movable frame 105, which in turn moves the cleaning scraper 107 on the movable rod 106 to the upper surface of the filter screen 103. This scrapes and cleans large impurities from the upper surface of the filter screen 103 and pushes them towards the outlet frame 108. The movement of the cleaning scraper 107 then moves the rubber block 110 on the connecting rod 109 into the receiving frame 111, opening the outlet frame 108. The cleaned impurities are then discharged through the outlet of the outlet frame 108. This cleaning of the filter screen 103 by the cleaning scraper 107 and the discharge of impurities by the outlet frame 108 prevents the accumulation of impurities in the crude oil on the filter screen 103, thus avoiding clogging.

[0021] Secondly, the collection rack 115 is fixedly connected to the oil inlet pipe 102 and is located on one side of the oil inlet pipe 102; the collection box 116 is disposed on the collection rack 115 and is located on the side of the collection rack 115 close to the outlet rack 108. The collection rack 115 is welded to the oil inlet pipe 102, and the collection box 116 is placed on the collection rack 115 and is located below the outlet of the outlet rack 108. The collection box 116 can collect the impurities discharged by the outlet rack 108 in a concentrated manner, which is convenient for operators to clean and process the discharged impurities.

[0022] Meanwhile, the rubber plug 112 is fixedly connected to the movable frame 105 and is located on the side of the movable frame 105 near the fixed cylinder 104. The rubber plug 112 is adhered to the movable frame 105, and the rubber plug 112 can prevent crude oil from leaking out of the fixed cylinder 104 in large quantities.

[0023] In addition, the locking bolt 113 is disposed on the fixed cylinder 104 and abuts against the movable frame 105. The locking bolt 113 is disposed on the fixed cylinder 104. By turning the locking bolt 113, it can abut against the movable frame 105 in the fixed cylinder 104, thereby locking the movement of the movable frame 105 when necessary.

[0024] Finally, the side plate 114 is fixedly connected to the cleaning scraper 107 and is located on one side of the cleaning scraper 107. There are two side plates 114, which are welded to the cleaning scraper 107. The side plates 114 can limit the impurities scraped and pushed by the cleaning scraper 107, so that the cleaning scraper 107 can push the scraped impurities into the guide frame 108.

[0025] When using the crude oil heating pretreatment device of this embodiment, when the filter screen 103 in the oil inlet pipe 102 of the crude oil pipeline needs to be cleaned, the operator moves the moving frame 105, which in turn moves the cleaning scraper 107 on the moving rod 106 to move the upper surface of the filter screen 103. This scrapes and cleans large impurities on the upper surface of the filter screen 103 and pushes them towards the outlet frame 108. At this time, the movement of the cleaning scraper 107 moves the rubber block 110 on the connecting rod 109 into the receiving frame 111, thereby opening the outlet frame 108. The cleaned impurities can then be discharged through the outlet of the outlet frame 108. Thus, the cleaning of impurities on the filter screen 103 by the cleaning scraper 107 and the discharge of impurities by the outlet frame 108 prevent a large amount of impurities in the crude oil from accumulating on the filter screen 103 and causing blockage.
