This invention discloses an immersion and purging device for zeolite modules, comprising an immersion tank and a blower mechanism. The immersion tank contains an immersion solution for immersing the zeolite modules, and a placement rack is provided on the immersion tank for placing the zeolite modules to be purged. An air outlet hood is provided at the air outlet end of the blower mechanism, correspondingly covering the placement rack and abutting the zeolite modules on the placement rack, allowing the air from the blower mechanism to completely penetrate the inner structure of the zeolite modules. Multiple immersion tanks are arranged in a row, and the placement rack is mounted on a movable support, which can move the placement rack to each immersion tank. The air outlet hood is separately connected to the blower mechanism and is rotatably mounted on the movable support. When the air outlet hood is flipped up, it exposes the placement rack; when the air outlet hood is flipped down, it abuts the zeolite modules on the placement rack. This invention enables the air from the blower mechanism to completely act on the zeolite modules to be purged, reducing the purging time.

The invention relates to the technical field of automobile engine tests, in particular to an engine hot test bench cooling liquid purging method and device and a vehicle. The method comprises the steps that after a hot test is finished, the gas-liquid mixing ratio of fluid in an engine is detected; the residual liquid amount of the cooling liquid is determined according to the fluid gas-liquid mixing ratio; and according to the residual liquid amount, generating a vibration excitation action of the electromagnetic vibration exciter to execute the vibration excitation action so as to purge the cooling liquid of the engine hot test bench, and ending purging until the residual liquid amount is smaller than a preset threshold value. Therefore, the problems that in the related technology, due to attachment of liquid to a water channel and a complex water channel structure, residual liquid is difficult to completely remove by driving cooling liquid or gravity drainage depending on compressed air, due to the fact that complex pipeline butt joint is needed in manual operation, consumed time is long, purging efficiency is low, and a large amount of compressed air is consumed in fixed purging, and the cost is low are solved. And resource waste caused by incapability of timely closing is avoided.

The invention discloses a conveying box purging device, a conveying box storage device and a conveying box purging control method.According to the conveying box purging device, a gas outlet pipeline is provided with a first branch and a second branch, the first branch is connected with a suction device, and the control device can control the suction device to suck gas before protective gas is introduced into a conveying box; according to the conveying box, gas in the conveying box is rapidly extracted, protective gas does not need to be used during extraction, waste of the protective gas can be reduced, when the protective gas is introduced subsequently, the protective gas can be introduced into the conveying box more rapidly due to low pressure in the pipeline and the conveying box, the blowing speed of the protective gas is increased, and the blowing efficiency is improved; after the humidity and / or oxygen concentration in the conveying box meets the requirement, under the condition that the gas outlet pipeline is closed, the protective gas is supplied at low flow, and when the protective gas cannot be maintained, purging is carried out at relatively large third flow, so that the atmosphere of the protective gas in the conveying box can be maintained to the maximum extent, and the consumption of the protective gas is reduced.

This utility model discloses a device suitable for simultaneous purging of multiple heat exchange tubes, including a platform. A movable frame is movably connected to the top of the platform. A connecting seat is movably connected to the inner side of the movable frame. A sliding block is movably connected to the inner side of the connecting seat. A first motor is fixedly connected to the front of the sliding block. A threaded rod is fixedly sleeved on the other end of the output shaft of the first motor. The other end of the threaded rod passes through the sliding block and extends into the interior of the sliding block, and is threadedly sleeved with a movable plate. The bottom of the movable plate is movably connected to the interior of the top of the sliding block. A hollow rod is fixedly connected to the left side of the movable plate, and a rotating plate is movably connected to the interior of the hollow rod. The quick switching function of the purging head and the two independently moving sets of purging heads in this application enable the device to simultaneously purge multiple heat exchange tubes and adapt to rapid purging operations of different types of heat exchange tubes.
