The invention claims to protect a hand-held descaling device based on ultrasonic technology for equalizing electrodes of valve cooling water circuits, which belongs to the technical field of ultrasonic non-destructive removal. The voltage equalizing electrode descaling device proposed by the present invention mainly includes a current injection module, a scale layer thickness detection module, a high-frequency electric signal generation module, a power amplification module, and a transducer signal module. The thickness detection module measures the potential of the equalizing electrode by applying current excitation, and determines the thickness of the equalizing electrode scaling according to different measurement impedances. The ultrasonic adjustment module has a built-in Powell algorithm, which intelligently optimizes the high-frequency electrical signal generation module through the measured thickness information. The frequency of the signal, the amplification factor of the power amplifier module, and the ultrasonic action time achieve the optimal descaling effect; finally, the ultrasonic wave is output through the transducer module and the scale layer on the electrode surface is removed by the cavitation effect. In the past, the overhaul of the converter valve required sampling and dismantling of the equalizing electrodes.

The invention discloses an aroma sustained-release capsule and a preparation method thereof. An aroma sustained-release capsule includes composite microspheres, the composite microspheres include several microsphere units, the exterior of the composite microspheres is provided with a matching capsule shell, the composite microspheres The ball diameter is smaller than the capsule shell diameter. The present invention also includes the preparation method of the fragrance sustained-release capsule. The present invention uses starch-β-cyclodextrin composite microspheres and xanthan gum to make aroma slow-release capsules, prolongs the single use time of the original aroma release agent to enhance the use effect, and effectively solves the problem of excessive aroma volatilization speed in the prior art. Fast, increasing the number of times of use causes waste of resources, environmental pollution and hazards to human health.

The invention relates to a new energy mining truck driving motor with a high-efficiency heat dissipation structure, including a motor, a friction disc, a friction wheel, a heat dissipation device, and an eccentric adjustment assembly; the friction disc is installed on the main shaft of the motor, and the friction wheel can rotate with the friction disc; heat dissipation The device is configured to increase the heat dissipation capacity as the friction wheel speed increases; the eccentric adjustment assembly includes a transmission rod and a connecting sleeve, the transmission rod can be set to rotate with the main shaft of the motor, a centrifugal adjustment block is arranged on the transmission rod, and a linkage is arranged in the centrifugal adjustment block. Mechanism and two threaded engaging blocks, the linkage mechanism is configured so that only one threaded engaging block fits with the connecting sleeve; the connecting sleeve is configured to engage with different threaded engaging blocks, so as to drive the friction wheel away from the center of the friction disc with the rotation of the transmission rod Move at different speeds and increase the rotational speed of the friction wheel. When the load of the motor decreases and the rotational speed of the spindle increases, the movement speed of the connecting sleeve increases steadily by switching the cooperation between the threaded engagement block and the connecting sleeve, thereby stably improving the heat dissipation capacity.

The invention discloses a lifting check valve which is easy to replace the spring. Mechanism, the outside of the spring replacement mechanism is provided with two left and right symmetrical disc limit mechanisms; when the elastic force of the check valve spring decreases, turn the elastic force adjustment lever to restore the elastic force of the check valve spring to the original state, thereby reducing the force of the check valve spring. The frequency of spring replacement prolongs the single use time of the check valve spring. At the same time, through the valve disc limit mechanism, when the spring is replaced, the limit block is in contact with the upper end surface of the spring sleeve, so that the valve disc cannot move upward under the action of water flow. Movement, so that the water flow cannot enter the drain through the disc movable chamber, so that the check valve spring can be replaced without turning off the water source, and the maintenance efficiency of the check valve spring is improved.

The invention belongs to the field of unmanned wave-piercing vehicles, in particular to an unmanned wave-piercing vehicle. With the help of the up and down movement of the double-body floating body in the water part, the invention can independently adjust the floating state of the aircraft and help the aircraft to perform concealed water operations, and proposes a multi-application method for the wave-piercing aircraft. A new design idea. In the present invention, by utilizing the floating body with a certain buoyancy to move freely up and down on the straight rod fixedly connected with the aircraft, the aircraft can always maintain a certain height difference with the liquid surface in both waves and still water, thereby ensuring navigation The floating state of the device remains unchanged and the platform equipment on the floating body is protected from major damage; at the same time, the structure of the floating body platform is smaller than that of the unmanned surface vehicle and has stronger concealment, which can complete the tasks that need to be completed above the water surface .

The invention relates to a cleaning method for filter cloth of a centrifugal machine, and particularly relates to a cleaning method and system for filter cloth of a centrifugal machine in wire cutting waste mortar recycling, aiming to provide a cleaning method and a cleaning system which can clean filter cloth of a scraper efficiently so as to solve the problems that in the prior art, the filter cloth of the scraper is not cleaned thoroughly, the residual impurities are high in content, and the filter cloth is required to be replaced frequently in the production process. The cleaning method comprises the following steps of (1) alkaline washing, (2) acid pickling, (3) washing, and (4) drying. The cleaning method and the cleaning system which are provided by the invention have the positive beneficial effects that the method is used for cleaning fine powder and polyethylene glycol in clearances of the filter cloth of the scraper clearly by the combined action of acid pickling, alkaline washing and ultrasonic wave, the filter cloth of the scraper can be effectively cleaned, the service life of the filter cloth is prolonged, and the cost is saved.

The invention belongs to the technical field of preparation of insulators for the construction of asphalt pavement road rollers and relates to an insulator for the low-temperature construction of road rollers and a method for preparing the same. The insulator is mainly prepared by mixing silicone oil, compound emulsifier, glycerin, pH regulator, preserving agent and water. The insulator has the advantages of high chemical stability, high high-low temperature resistance, no corrosion to steel wheels, small amount of coating, lasting insulating effect, environment friendliness and the like. By using the insulator, the asphalt mixture pavement is guaranteed to be constructed at the ultralow temperature (15 DEG C below zero), so that the working season is greatly prolonged; and during normal-temperature construction, by using the insulator, the mixing temperature of the asphalt mixture is reduced to 15 to 20 DEG C under the condition of unchanging the compaction degree and the emitted greenhouse gases are reduced in the mixing process and the environment-friendly and energy saving requirements are met.
