The invention discloses a low-temperature pump system with a regenerating function. The low-temperature pump system comprises a cold pump shell, a cold head, a cold pump control module and a heating module, wherein the cold head is positioned in the cold pump shell, and is used for adsorbing gas in the cold pump shell in a vacuum state, and gas covers the cold head after being condensed; the cold pump control module is used for controlling a vacuum adsorbing process of a low-temperature pump and a regenerating process of the low-temperature pump; the heating module is arranged in the cold pump shell; and in the regenerating process of the low-temperature pump, the heating module is used for heating the cold pump shell to prevent heat transmission from being quickened due to the fact that nitrogen gas is introduced in the regenerating process of the low-temperature pump, and therefore, the temperature of the cold pump shell is prevented from being lower than the environment temperature to generate condensed water.

The invention relates to fog seal modified emulsified asphalt which comprises the following components by weight: 18-35% of asphalt, 8-18% of an asphalt modifying agent, 5-12% of an asphalt regenerating agent, 1-4% of a compound emulsifying agent and 50% of water. The preparation method comprises the following steps: directly adding the asphalt modifying agent and the asphalt regenerating agent to hot melt asphalt for mixing to prepare modified asphalt; mixing and emulsifying the modified asphalt and an aqueous solution of the compound emulsifying agent through a colloid mill; and mechanically stirring to prepare the fog seal modified emulsified asphalt. The prepared fog seal modified emulsified asphalt has the advantages of good storage stability, good water dilutability, environmental protection in use, good surface consolidation performance after construction, good abrasion resistance, difficult sticking off by wheels, short traffic close time, improvement of construction conditions, improvement of construction efficiency, good water seal function, asphalt pavement water damage prevention, pavement structure protection and extension of pavement service life.

The invention discloses a friction electric dust removing device and a dust removing method, the friction electric dust removing device includes an outer layer casing and an inner layer casing which are in a jacket layer structure, the outer layer casing is a sealing structure, is provided with a liquid discharge port at the bottom; the inner layer casing is provided with a plurality of gas guide holes, the inner wall of the inner layer casing is provided with electrodes, a plurality of dust collection units are arranged in the inner layer casing, surface materials of part of or all of the dust collection units are different in electronegativity from materials of the electrodes, a spray head is introduced from the outer layer casing, is controlled by a liquid inlet switch, and is used for cleaning the dust collection units or the electrodes; the inner layer casing rotates to enable the dust collection units or the electrodes to mutually collide to form an electrostatic field, a gas entering from a gas inlet in turn passes through the dust collection units, a gap between the outer layer casing and the inner layer casing, the dust collection units and a gas outlet for filtration of particles in the gas. The spray head can automatically clean the dust collection units and the electrodes in the dust removing device, and prolong the service life of the device.

The invention provides a multipurpose machine for filtration, concentration and washing. The machine comprises a base, a front bracket, a rear bracket, a front support plate, a rear support plate, a hydraulic oil cylinder, an oil cylinder seat, a movable pressure plate, an impeller, a filter plate, a washing filter plate, a center shaft, a reduction gearbox, a motor, a regulation valve, a filtrate branch pipe and a filtrate manifold, wherein the front and rear brackets are arranged on the base; the hydraulic oil cylinder is arranged on the front bracket through the oil cylinder seat; one end of the center shaft is arranged on the movable pressure plate in a sleeving manner, and horizontally penetrates through the impeller, the filter plate, the washing filter plate and a rear support seat in sequence, and the other end of the center shaft is connected with an output shaft of the reduction gearbox; the motor and the regulation valve are arranged on the reduction gearbox. The multipurpose machine is compact in structure; materials can be continuously fed, and filter cakes can be discharged during filtration, so that the machine is high in production efficiency and productivity; the machine automatically runs, so that the operation intensity is low; the machine is convenient to operate and maintain, and low in production cost and has the energy-saving effect, and the consumption is lowered; a cross flow filtration mode is adopted, so that a filter cloth regeneration function is realized; the machine is wide in application range.
