Description

Technical Field

[0001] This utility model relates to the technical field of turnover barrel processing equipment, and in particular to a rapid cleaning and drying channel for general-purpose turnover barrels for oilfield chemical additives. Background Technology

[0002] In oilfield extraction, drilling, and oil and gas processing, a wide variety of chemical additives (such as drilling fluid additives, demulsifiers, corrosion inhibitors, and bactericides) are widely used. These additives are typically prepared by suppliers or on-site laboratories and then transported, stored, and filled in dedicated, universal reusable containers. Before reuse, these containers must be thoroughly cleaned and dried to avoid cross-contamination between different chemical additives, prevent residues from affecting the performance of new additives, and ensure the containers are clean and dry for easy storage and transportation.

[0003] In practice, the following problems commonly exist in the cleaning and drying of transfer containers at oilfield sites or chemical service bases using existing technologies:

[0004] Cleaning and drying are usually carried out in two separate areas, requiring manual handling of turnover drums. The process is disjointed, time-consuming and labor-intensive, and cannot meet the needs of batch and rapid turnover.

[0005] Natural air drying or simple drying room drying is commonly used. Natural air drying is greatly affected by the weather and takes a long time; simple drying rooms often have uneven temperature, high energy consumption, and lack effective hot air circulation and dehumidification mechanisms, resulting in low drying efficiency and easy retention of moisture on the inner wall of the drum, which brings many inconveniences.

[0006] Therefore, this utility model provides a rapid cleaning and drying channel for universal turnover buckets of oilfield chemical additives. Utility Model Content

[0007] The purpose of this invention is to address the shortcomings of existing technologies and provide a continuous processing channel that integrates rapid cleaning, efficient drying, and thermal energy circulation to improve the processing efficiency of turnover barrels, ensure the quality of cleaning and drying, reduce energy consumption and labor costs, and meet the high-standard and fast-paced production needs of oilfield sites.

[0008] To achieve the above objectives, this utility model adopts the following technical solution: a rapid cleaning and drying channel for universal turnover barrels of oilfield chemical additives, including a drying constant temperature chamber.

[0009] A secondary heating chamber is fixedly connected to the top of the drying constant temperature chamber. A fan is fixedly connected to one side of the secondary heating chamber. A cleaning water tank is fixedly connected to one side of the fan. A water pump is fixedly connected to one side of the cleaning water tank. A drain pipe is installed between the water pump and the cleaning water tank. A conveying air duct extending into the interior of the drying constant temperature chamber is installed on the other side of the secondary heating chamber. Equally spaced internal placement racks are installed inside the drying constant temperature chamber. Heating rods are installed on the top of each internal placement rack.

[0010] A primary heating chamber is fixedly connected to one side of the drying constant temperature chamber. A fan mounting frame is fixedly connected inside the primary heating chamber. A bidirectional fan is fixedly connected inside the fan mounting frame. Equally spaced heating wires are fixedly connected to one side of the fan mounting frame. When the heating wires rotate, a primary heating process is performed. The bidirectional fan, rotating in the forward direction, blows the heating gas into the drying constant temperature chamber for storage. When the bidirectional fan rotates in the reverse direction, it extracts the gas from the primary heating chamber and the drying constant temperature chamber for periodic ventilation.

[0011] The top of the secondary heating box is equipped with a heating plate mounting frame, and heating plates that are evenly distributed and extend into the secondary heating box are installed inside the heating plate mounting frame for secondary heating treatment.

[0012] In a preferred embodiment, the primary heating chamber has an exhaust slit on the side away from the drying constant temperature chamber; the cleaning water tank is fixedly connected to an internal inlet water pipe extending into the drying constant temperature chamber on the side away from the drain pipe; a sieve partition is installed inside the drying constant temperature chamber on one side of the internal placement rack; an equidistantly distributed air outlet pipe is installed on one side of each sieve partition; one end of each air outlet pipe is connected to a conveying air pipe; a first valve is fixedly connected to the outside of each air outlet pipe; an equidistantly distributed air outlet branch pipe is installed on one side of each air outlet pipe; a fan is installed between the internal inlet water pipe and the secondary heating chamber; the output end of the fan is fixedly connected to a drying air outlet pipe; a second valve is fixedly connected to the outside of the internal inlet water pipe; and a third valve is fixedly connected to the outside of the drying air outlet pipe.

[0013] In a preferred embodiment, equidistantly distributed filters are installed on both sides of the fan mounting frame. A temperature sensor is installed on the outer side of the filter. The temperature sensor is used to monitor the temperature change inside the primary heating chamber in real time. The filter is used to filter air during intake and exhaust. A top inspection cover is installed on the top of the primary heating chamber. The top inspection cover is used to facilitate the opening and maintenance of the interior of the primary heating chamber. A water filling cover is installed on the top of the cleaning water tank.

[0014] In a preferred embodiment, a buzzer is fixedly connected to the top of the drying constant temperature chamber. The buzzer is located on the side close to the primary heating chamber. A control panel is fixedly connected to the side of the primary heating chamber away from the drying constant temperature chamber. The buzzer, heating rod, first valve, water pump, bidirectional fan, heating wire, temperature sensor, secondary heating chamber, and fan are all electrically connected to the control panel.

[0015] In a preferred embodiment, the drying constant temperature chamber is equipped with equidistantly distributed maintenance opening and closing plates on both sides, and handles are installed on the outer side of each maintenance opening and closing plate.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] Equipped with a drying constant temperature chamber, a cleaning water tank, and a primary heating chamber, the cleaning program is started via the control panel. The water pump operates, drawing cleaning water from the cleaning water tank. Simultaneously, the second valve on the outside opens, pumping water through an internal connection pipe into the drying constant temperature chamber to clean the storage containers placed inside. Alternatively, the water pump can directly clean the external storage containers. The operating mode can be switched as needed to form a closed-loop or semi-closed-loop hot air circulation, improving thermal energy utilization. To further enhance drying efficiency and flexibility, a secondary heating chamber is included. Its internal heating plate can supplement the heating of the circulating air. The fan is turned on, drawing the partially utilized but still residually hot humid air from the drying constant temperature chamber into the secondary heating chamber through a conveyor duct. The residual heat air is then reheated by the heating plate. After dehumidification, the air becomes high-temperature dry air, which can also be directly discharged through the drying exhaust duct to dry external equipment. If high-intensity drying is not required, the primary heating chamber can be shut down, and only the secondary heating chamber can be used for auxiliary or maintenance drying to save energy. The temperature sensor monitors the temperature of the primary heating chamber in real time and feeds it back to the control panel to achieve constant temperature control. The buzzer alarms when the program ends or a fault occurs. After drying is completed, a flexible hose can be connected to the drying exhaust duct for targeted and rapid drying of specific locations. For equipment maintenance, internal maintenance can be carried out through the top inspection cover and inspection opening plate. Water can be added to the cleaning water tank through the water filling cover. The outside of the inspection opening plate is equipped with a handle, which is used to facilitate the opening of the drying constant temperature chamber for routine maintenance.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figures 1-5As shown, this embodiment provides a technical solution: a rapid cleaning and drying channel for general turnover barrels of oilfield chemical additives, including a drying constant temperature box 1, a secondary heating box 4 fixedly connected to the top of the drying constant temperature box 1, a fan 41 fixedly connected to one side of the secondary heating box 4, a cleaning water tank 2 fixedly connected to one side of the fan 41, a water pump 23 fixedly connected to one side of the cleaning water tank 2, a drain pipe 22 installed between the water pump 23 and the cleaning water tank 2, a conveying air duct 42 extending into the interior of the drying constant temperature box 1 installed on the other side of the secondary heating box 4, and an internal placement rack 14 evenly distributed inside the drying constant temperature box 1, with heating rods 15 installed on the top of each internal placement rack 14;

[0030] In this scheme, a primary heating chamber 3 is fixedly connected to one side of the drying constant temperature chamber 1. A fan mounting frame 32 is fixedly connected inside the primary heating chamber 3. A bidirectional fan 33 is fixedly connected inside the fan mounting frame 32. An equally spaced heating wire 34 is fixedly connected to one side of the fan mounting frame 32. When the heating wire 34 is turned, it performs a primary heating treatment. The bidirectional fan 33 blows the heating gas into the drying constant temperature chamber 1 for storage through forward rotation. When the bidirectional fan 33 is turned in reverse, it extracts the gas inside the primary heating chamber 3 and the drying constant temperature chamber 1 for periodic ventilation.

[0031] In this solution, a heating plate mounting frame 44 is installed on the top of the secondary heating box 4. Heating plates that are evenly distributed and extend into the secondary heating box 4 are installed inside the heating plate mounting frame 44. Secondary heating is carried out through the heating plates, which speeds up the overall drying and heating efficiency. At the same time, the equipment inside the primary heating box 3 can be turned off, and only the heating plates inside the secondary heating box 4 are used for auxiliary drying, which saves electricity consumption to a certain extent.

[0032] Going further, such as Figures 1-4 As shown: In this scheme, the heating box 3 is provided with an exhaust slit on the side away from the drying constant temperature box 1. The cleaning water tank 2 is fixedly connected to an internal access water pipe 21 extending into the drying constant temperature box 1 on the side away from the drain pipe 22. The drying constant temperature box 1 is equipped with a sieve partition 16 on the side of the internal placement rack 14. The sieve partition 16 is equipped with equidistantly distributed air outlet pipes 17 on one side of the sieve partition 16. One end of the air outlet pipe 17 is connected to the conveying air pipe 42. The outside of the air outlet pipe 17 is fixedly connected with a first valve 18. The air outlet pipe 17 is equipped with equidistantly distributed air outlet branch pipes 19 on one side of the air outlet pipe 17.

[0033] In this design, a fan 41 is installed between the internal water pipe 21 and the secondary heating box 4. The output end of the fan 41 is fixedly connected to the drying air outlet pipe 43. A second valve is fixedly connected to the outside of the internal water pipe 21, and a third valve is fixedly connected to the outside of the drying air outlet pipe 43. The second valve is used to control the opening and closing of the internal water pipe 21, which facilitates the injection of cleaning water into the drying constant temperature box 1 for regular maintenance and cleaning. The third valve is used to control the opening and closing of the drying air outlet pipe 43. The drying air outlet pipe 43 is used to connect other hoses to assist the turnover drum in rapid drying.

[0034] Going further, such as Figures 1-5 As shown: In this solution, filter screens 35 are installed on both sides of the fan mounting frame 32 at equal intervals. Temperature sensors 36 are installed on the outside of the filter screens 35. The temperature sensors 36 are used to monitor the temperature changes inside the primary heating box 3 in real time. The filter screens 35 are used to filter air when it is inlet and outlet.

[0035] In this design, a top inspection cover 37 is installed on the top of the primary heating box 3. The top inspection cover 37 is used to facilitate the inspection and maintenance of the interior of the primary heating box 3 after opening. A water filling cover 24 is installed on the top of the cleaning water tank 2. The water filling cover 24 is used to add the required water to the cleaning water tank 2 after opening.

[0036] In this scheme, a buzzer 13 is fixedly connected to the top of the drying constant temperature chamber 1. The buzzer 13 is located on the side close to the primary heating chamber 3. A control panel 31 is fixedly connected to the side of the primary heating chamber 3 away from the drying constant temperature chamber 1. The buzzer 13, heating rod 15, first valve 18, water pump 23, bidirectional fan 33, heating wire 34, temperature sensor 36, secondary heating chamber 4 and fan 41 are all electrically connected to the control panel 31. The control panel 31 is used to control the operation of the buzzer 13, heating rod 15, first valve 18, water pump 23, bidirectional fan 33, heating wire 34, temperature sensor 36, secondary heating chamber 4 and fan 41, realizing unified management of electrical equipment.

[0037] Going further, such as Figures 1-5 As shown in the figure, in this scheme, maintenance opening and closing plates 11 are installed on both sides of the drying constant temperature chamber 1 at equal intervals. Handles 12 are installed on the outer side of the maintenance opening and closing plates 11. The maintenance opening and closing plates 11 and the handles 12 are used to facilitate the opening of the interior of the drying constant temperature chamber 1 for daily maintenance.

[0038] In this scheme, the primary heating box 3 provides basic hot air circulation; the secondary heating box 4 serves as a waste heat recovery and reheating device. The inlet of its fan 41 is connected to the drying constant temperature box 1 through the conveying air duct 42. The internal water pipe 21 is an independent water circuit, which is physically separate from the fan 41 and its pipes, and is only adjacent to the position shown in the figure.

[0039] This solution integrates cleaning, primary drying, and waste heat recovery and re-drying into a coherent physical space, achieving rapid processing and solving the problem of discrete processes in the background technology. The secondary heating box 4 is not only a backup heater, but its core function is to heat up and dehumidify the waste heat air after one cycle for reuse. It forms a stepped heating with the primary heating box 3, reducing the energy consumption of heating air from zero and improving the overall thermal efficiency. This is an energy-saving effect that cannot be achieved by simply adding heating devices.

[0040] Filter 35 is used to filter chemical dust; the entire outer side of the equipment is coated with corrosion-resistant material, and the overall design facilitates installation and maintenance at the oilfield site.

[0041] Working principle:

[0042] like Figures 1-5 As shown:

[0043] The system is equipped with a drying constant temperature chamber 1, a cleaning water tank 2, and a primary heating chamber 3. During operation, the control panel 31 is opened. The control panel 31 controls the operation of the buzzer 13, heating rod 15, first valve 18, water pump 23, bidirectional fan 33, heating wire 34, temperature sensor 36, secondary heating chamber 4, and fan 41, achieving unified management of the electrical equipment. The specific process is as follows:

[0044] Preparation and feeding:

[0045] Open the inspection and opening plate 11, and place the empty turnover barrel to be processed on the internal placement rack 14 inside the drying constant temperature box 1. The placement rack 14 is used to stably support the barrel and facilitate air circulation inside and outside the barrel.

[0046] Cleaning stage:

[0047] The cleaning program is started via control panel 31. Water pump 23 operates, drawing cleaning water from cleaning water tank 2. At this time, the second valve on its outside is opened, and water is pumped into the drying constant temperature chamber 1 through the internal water pipe 21 to clean the turnover drum placed inside the drying constant temperature chamber 1. Alternatively, the water pump 23 can be used to clean the turnover drum directly outside. The operation mode can be switched as needed. A water filling cover 24 is installed on the top of cleaning water tank 2. The water filling cover 24 is used to add the required water into cleaning water tank 2 after opening. After cleaning is completed, the second valve is closed to stop the water supply.

[0048] First-stage drying:

[0049] When the drying program begins, the heating box 3 starts up, the heating wire 34 inside heats up, the bidirectional fan 33 runs in the forward direction, and the external air is heated after being filtered by the filter screen 35 to form dry hot air, which is blown into the drying constant temperature box 1.

[0050] Hot air is blown evenly onto the turnover drum through the air outlet duct 17 and the air outlet branch pipe 19 inside the drying constant temperature chamber 1, taking away the moisture on its surface and inner wall. The heating rod 15 at the bottom of the chamber helps to maintain the ambient temperature inside the chamber and prevent condensation. The humid hot air is drawn back to the primary heating chamber 3 by the suction of the bidirectional fan 33. During this process, part of the high humidity exhaust gas can be discharged through the exhaust slit on the side of the primary heating chamber. There should be a controllable damper at the exhaust slit. The other part is mixed with the replenished fresh air and reheated by the electric heating wire 34 to form a closed-loop or semi-closed-loop hot air circulation, which improves the thermal energy utilization rate.

[0051] Secondary heating:

[0052] To improve drying efficiency and flexibility, a secondary heating box 4 is provided. Its internal heating plate can supplement the heating of the circulating air. When the fan 41 is turned on, the humid air in the drying constant temperature box 1, which has been initially utilized but still has residual heat, is drawn into the secondary heating box 4 through the conveying air duct 42. The residual heat air is heated and dehumidified again by the heating plate and becomes high-temperature dry air. It can also be directly discharged to external equipment for drying through the drying air outlet duct 43. If high-intensity drying is not required, the primary heating box 3 can be turned off and only the secondary heating box 4 can be used for auxiliary or maintenance drying to save energy.

[0053] Accessibility and Control:

[0054] Temperature sensor 36 monitors the temperature of primary heating chamber 3 in real time and feeds it back to control panel 31 to achieve constant temperature control. Buzzer 13 alarms when the program ends or a fault occurs. After drying, a flexible hose can be connected to the drying exhaust duct 43 for targeted and rapid drying of specific locations. During equipment maintenance, internal maintenance can be carried out through the top inspection cover 37 and the inspection opening and closing plate 11. Water can be added to the cleaning water tank 2 through the water filling cover 24. Handles 12 are installed on the outside of the inspection opening and closing plate 11. The inspection opening and closing plate 11 and the handles 12 are used to facilitate the opening of the drying constant temperature chamber 1 for routine maintenance.

[0055] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
