The utility model discloses a special line sweeping integrated pump truck for an oil field, which relates to the technical field of oil field line sweeping and comprises a truck body, a transition tank is connected to one side of the top of the truck body, a valve is connected below the outer surface of the transition tank, a flow meter is mounted at one end of the valve, and a radar liquid level meter and a pressure release valve are respectively mounted at the top of the transition tank. A vertical plunger pump is installed on the other side of the top of the vehicle body, the fluid input end of the vertical plunger pump is connected with an inlet pipe, and the fluid output end of the vertical plunger pump is connected with an outlet pipe. One end of the inlet pipe and one end of the outlet pipe are connected with sealing plates, and worms penetrate through one sides of the sealing plates. Through the arrangement of the valve, the transition tank, the flow meter, the radar liquid level meter and the pressure release valve, the tank, the pump and the vehicle are integrated, so that the working efficiency is improved, and the energy consumption is reduced; the flow meter and the radar liquid level meter are used for measuring the line sweeping mixed liquid entering the transition tank at the same time, and the tank overflowing phenomenon is avoided; the integrated vehicle does not need to independently get on a pump truck and a transition tank, and the working efficiency is improved.

This invention discloses a universal control interface for pure hardware timing management, comprising a set of basic control signal transmission channels consisting only of four basic channels: power, reset, clock, and wake-up. This interface enables control communication between a processorless, software-free hardware timing management unit (composed solely of gate circuits and state mechanisms) and an external processing unit. The pure hardware timing management unit is the sole and exclusive control entity for the four basic channels, with its control logic completely fixed and tamper-proof. The interface also includes status monitoring, interactive control, and auxiliary control channels, possessing a robust fault-tolerant mechanism. This invention also protects hardware modules and electronic devices containing this interface. This invention physically eliminates the security risks of software control interfaces, achieving a system communication error rate of less than one part per quadrillion and standby power consumption of less than 1 milliwatt. It is suitable for fields with high security and high reliability requirements, such as intelligent computing centers, industrial control, automotive electronics, and consumer electronics.

In some embodiments, a reusable filter system for interchangeable pleated filters is provided, the reusable filter system comprising: (a) a reusable frame including a first retainer, a second retainer, a third retainer, and a fourth retainer; (b) at least one flexible sheet configured to be attached to at least a portion of an upper pleat top face and / or a lower pleat top face and extending outwardly from a first pleat edge and a second pleat edge; and (c) at least one plug, wherein the first retainer, the second retainer, the third retainer, and the fourth retainer are configured to reversibly connect to each other to form the reusable frame, and wherein each of the first retainer, the second retainer, the third retainer, and the fourth retainer further includes a plug receiving portion sized and shaped to receive the plug. Other exemplary embodiments are described herein. In some embodiments, the reusable filter system is user-friendly and environmentally friendly, and reduces transportation costs.

This utility model relates to the field of silk fabric processing technology and discloses a clean silk fabric storage device, including a box. An air intake motor is fixedly installed inside the upper end of the box, and a fan blade is fixedly connected to the upper end of the output shaft of the air intake motor. A protective net is fixedly installed above the fan blade on the upper end of the box. This clean silk fabric storage device, through the air intake motor driving the fan blade to rotate, draws outside air into the box. As the air passes through the air intake duct, an electric heating element heats it, effectively reducing air humidity and achieving a moisture-proof function, preventing the silk fabric from becoming moldy and deteriorating due to dampness. Simultaneously, after being filtered by the filter element in the filter chamber, the air enters the diversion channel through a second one-way valve, and is then evenly blown out by a hollow hanging rod with perforated surfaces. This not only maintains the cleanliness of the storage environment but also cleans the surface of the silk fabric, reducing dust adhesion and preventing physical wear caused by dust, thus ensuring product quality.
