A vane type hand pump with a siphon function comprises a pump body, a rotor, vanes and a pump shaft. A vane pump modular unit is mounted in an inner cavity of the pump body and comprises a pump chamber assembly and a rotor assembly, an arc-triangle equal-width cam trough plate serves as a guide mechanism of the vanes, and the rotor and two side plates are connected into a whole and synchronously rotate. Therefore, in operation, end faces and side faces of the vanes cannot emit heat due to friction, vibration and noise caused by fluid trap are avoided, and a switching valve is mounted in the modular unit. In the water delivery process, the vane type hand pump has the siphon function only when water level difference meets requirements and the switching valve is opened, and fluids are automatically discharged. Compared with a traditional reciprocating manual pump, the pump with the function can save half the time by absorbing the same capacity of water, rotation of a handle is more suitable for the operation habit of people as compared with vertical swing of a swing arm, people are not easily fatigued, and the pump can be conveniently and rapidly maintained only by replacing a module.

The invention provides a marine lever float type steam trap, comprising: a bonnet with a floating ball inside and a lever assembly driven by the float; a valve body fixedly connected to the bonnet, and a The first and second cavity channels, the condensed water and uncondensed steam in the ship steam pipeline enter the valve cover from the first cavity channel, and the condensed water in the valve cover is discharged from the second cavity channel; the drainage assembly, It is arranged between the valve cover and the valve seat, and the drainage assembly is driven by the lever assembly to control the discharge of condensed water in the valve cover to the second cavity channel; the top of the exhaust assembly is arranged inside the valve cover, and the bottom of the exhaust assembly The pierced valve body is located in the second cavity channel. When the temperature of the uncondensed steam in the bonnet is lower than the first temperature threshold, the steam in the bonnet will be discharged to the second cavity channel through the exhaust assembly. The temperature of the uncondensed steam is higher than the first temperature threshold, and the steam is prevented from being exhausted to the channel of the second cavity through the exhaust assembly.

The invention discloses a pyrolysis oil-gas-water synchronous condensing and oil-water separation recovery system and method. The method comprises the following steps that dry oil-containing sludge is added into a pyrolysis reactor to generate pyrolysis oil and gas; the pyrolysis oil and gas is subjected to gas and solid separation through a cyclone separator; the purified pyrolysis oil and gas is pressurized through an oil-gas compressor, and is fed into an oil-gas-water cavity of an oil-gas-water synchronous condensing separator; pyrolysis oil gas and water is condensed on the surface of an oil-water separating membrane after being subjected to condensing heat exchange; generated water drips are transferred to a circulation cooling water cavity, enter a circulation cooling water tank through a circulation cooling water pump and further return to the circulation cooling water cavity; oil drips are recovered into an oil recovering tank through an oil drip discharging opening of the oil-gas-water cavity; non-condensable gas exhausted from the oil-gas-water cavity enters a non-condensable gas drying recovery system through an oil-gas pressure reducing valve and returns to a heating furnace as fuels. The system and the method have the advantages that the oil-water separation recovery is realized while the pyrolysis oil and gas is condensed; the condensing effect is good; the system and the method are applicable to the heat chemical treatment process of oil-containing sludge.

The invention relates to a recovery device, in particular to a boiler water cooling recovery device. The purpose of the present invention is to provide a boiler water cooling recovery device with better filtering effect and convenient cleaning of the filter screen. The invention provides such a boiler water cooling and recycling device, which includes a support plate and a water storage tank, the bottom of the water storage tank is provided with support plates on both sides; the support block, the upper part of one side of the water storage tank is provided with the support block; the drain pipe, the support block The upper part is provided with a drain pipe, and the other end of the drain pipe is located above the water storage tank; the cooling mechanism, the upper part of one side of the water storage tank is provided with a cooling mechanism; the drainage mechanism, the upper part of one side of the water storage tank is provided with a drainage mechanism, and the drainage mechanism is located on one side of the cooling mechanism. Through the cooperation of the cooling mechanism and the drainage mechanism, the invention can use the water circulation to cool and recover the boiler water when the boiler water is discharged to the outside.

The invention discloses a 3D inner arc polishing machine, comprising: a frame, a lower plate assembly, a rotary linkage device installed through the lower plate assembly, several station assemblies arranged on the rotation linkage device, and a vacuum unit connected to the station assembly. The device, the upper plate assembly arranged above the lower plate assembly, a number of polishing devices that run through the upper plate assembly and correspond to the station assemblies one by one, and the grinding liquid supply system arranged on the lower surface of the upper plate assembly. The lower plate assembly drives the rotary linkage device and the station assembly to move back and forth; the rotary linkage device drives the station assembly to rotate in the same direction; the upper plate assembly drives the polishing device to move up and down, left and right; the polishing device can be lifted up and down and pushed sideways, and the station assembly The workpiece on the surface is polished. The polishing device and the station components of the present invention can move in multiple directions to meet the polishing requirements of curved surface workpieces; the pressure regulating device can offset the self-weight of the mechanism to ensure the stability and accuracy of the pressing pressure; the production efficiency is high, and the polishing uniformity is effectively improved sex.

The invention relates to a lysimeter for automatically monitoring a conversion process of soil water and underground water in a paddy rice. The lysimeter comprises a lysimeter area, an observation pond, an air pressure adjusting pipe, a pervious pipe, a valve, a filter, a positioning water tank, a positioning water tank guide rail, a valve, a skip bucket water meter, a water supplementing box, a water supplementing opening, a ventilation pipe and a water level gauge, which belongs to the field of agriculture science, and particularly relates to a device for acquiring conversion amount of soil water and underground water in the field. The lysimeter has the beneficial effects that (1) the lysimeter which can precisely measure the conversion amount of the soil water and underground water in the paddy field is provided; (2) the lysimeter can automatically supplement and discharge the water; (3) the underwater supplement amount measurement precision of the lysimeter can reach 0.07 mm; (4) the water leakage amount measurement precision of the lysimeter can reach 0.01 mm; and (5) the water supplementing and water discharging variation following time of the lysimeter is smaller than 5 minutes.
