An inner shell is arranged in the outer shell, an opening is formed in the lower end of the inner shell, a left bin and a right bin are arranged in the inner shell, a middle side wall is shared between the left bin and the right bin, an atomizing core is installed in the left bin, the right bin is an oil storage bin, and a rope penetrating through hole penetrating through the left bin and the right bin is formed in the position, close to the opening, of the middle side wall. The atomizing core is connected with an oil guide rope, the other end of the oil guide rope penetrates through the rope penetrating through hole to the right bin, and the connecting end, connected with the atomizing core, of the oil guide rope is higher than the rope penetrating through hole. Oil seal parts are arranged at openings in the lower ends of the left chamber and the right chamber; and an air inlet through hole communicated with the atomizing core is formed in the oil seal part corresponding to the left chamber. An air outlet through hole is formed in the upper end of the left chamber; and a suction nozzle part is arranged at the upper end of the shell corresponding to the upper part of the left chamber. By means of the scheme, the problem that tobacco tar leaks from the interior of the atomization core tube easily due to the fact that tobacco tar is completely soaked in tobacco tar storage cotton of an existing integrated electronic cigarette is solved, and freshness of the tobacco tar is kept.

This utility model discloses a pressure sensor core packaging structure, comprising a base, a patch assembly, a filling structure, a strain gauge, and a pressure plate. The base has a receiving cavity, an opening, and an oil filling hole. The opening communicates with the receiving cavity, and the oil inlet end of the oil filling hole is positioned close to the opening. The patch assembly and the filling structure are both housed within the receiving cavity. After the patch assembly is placed at the bottom of the receiving cavity, the filling structure fills the receiving cavity. The strain gauge and the pressure plate are sequentially fixed to the opening of the base, with the strain gauge located between the base and the pressure plate. The strain gauge and / or the pressure plate are sealed to the base. A gap exists between the strain gauge and the filling structure, and this gap is configured to be filled with oil through the oil filling hole, which is then sealed after being filled with oil. A detection port is provided on the pressure plate. This patent employs a unique core packaging structure, improving the application flexibility of oil-filled packaged pressure sensor products.

The utility model discloses a gear shifting system and agricultural machinery. An output shaft of a driving part of the gear shifting system is in transmission connection with a driving shaft of a first pump; an output shaft of the hydraulic motor is in transmission connection with an input shaft of the gearbox; two first communication ports of the hydraulic motor are communicated with two oil ports of the first pump in a one-to-one correspondence manner; the switch control valve, the hydraulic motor and the first pump are arranged in parallel; two second communication ports of the switch control valve are communicated with two oil ports of the first pump in a one-to-one correspondence manner; the output shaft of the driving part is further in transmission connection with a driving shaft of the second pump, an oil inlet of the second pump is communicated with the oil tank, an oil outlet of the second pump is communicated with a loop formed by the hydraulic motor and the first pump to supplement oil to the loop, and the oil outlet of the second pump is further communicated with a gear shifting oil inlet of the hydraulic gear shifting assembly to be used for driving gear shifting so as to enable the gearbox to shift gears. The gear shifting system is simple in structure, low in production cost, good in collaboration, good in working stability and reliability and capable of rapidly and efficiently shifting gears and prolonging the service life of the gear shifting gear ring.

This application relates to the field of thin oil lubrication station technology and discloses a lubrication station for electric steam turbines, including two fixed cylinders. An inlet pipe is fixedly connected to the top of each cylinder, and an outlet pipe is fixedly connected to the bottom of each cylinder. A control valve is fixedly installed on both sides of the inlet and outlet pipes. A filter cartridge is detachably fixed to the inner side of each cylinder. This invention uses a drive mechanism to move a sliding component and a movable ring, causing high-pressure clean lubricating oil to be sprayed onto the outer wall of the filter cartridge through progressively decreasing height nozzles. Backflushing cleaning occurs when the nozzle openings are in contact with the outer wall of the filter cartridge. The sliding component moves to scrape away impurities adhering to the inner wall of the filter cartridge and pushes them to a point near the drain pipe for rapid discharge. This achieves filter cartridge regeneration without disassembling the filter cartridge and reduces the amount of oil required for backflushing, thus improving the reliability of continuous operation of the lubrication station.

The invention belongs to the field of petrochemical industry, and provides a treatment method for overflow of oil-containing and odor-resistant cold coke water of needle coke, a contact cooling tower is newly added and is divided into an upper independent part and a lower independent part, the lower part is used for cooling and purging oil gas, and the upper part is used for overflow treatment of the cold coke water, so that function division is realized; purging oil gas from a coke tower firstly enters the lower portion of the contact cooling tower to be cooled, the cooled gas phase enters the air cooler to be cooled, and follow-up treatment is carried out after separation of the separation tank; coke cooling water from a coke tower overflows and then enters the upper portion of the contact cooling tower, a flocculating agent is added to promote oil products in the coke cooling water to be gathered at the tower bottom of the upper portion and then extracted, a water phase obtained after oil removal enters the coke cooling water storage tank to be recycled, and a gas phase is discharged from the tower top and is subjected to follow-up treatment through the air cooler. The method provided by the invention can effectively solve the problems that in the overflow process of the cold coke water of the needle coke, oil products contained in the coke enter the storage tank along with the cold coke water to cause oil accumulation in the tank, and the oil products are mixed into the cold coke water system to cause peculiar smell in the tank area.
