The utility model discloses a kind of range hood, including shell, exhaust device and oil cup;Shell has suction panel and the smoke collection cavity located in the inboard of suction panel, and suction panel has smoke collection cavity, first air inlet is equipped in smoke collection cavity, and first air inlet is communicated with smoke collection cavity;Exhaust device suction oil fume through first air inlet, and exhaust oil fume from smoke collection cavity;Oil cup is connected on shell, for receiving the oil liquid discharged by smoke collection cavity.This utility model's range hood, open smoke collection cavity on suction panel, first air inlet is arranged in smoke collection cavity, and oil fume towards suction panel will first enter smoke collection cavity, then flow into first air inlet, smoke collection cavity can play the effect of flow collection to oil fume, prevent oil fume from easily escaping from the area near first air inlet, to increase the residence time of oil fume near first air inlet, so that oil fume can be more fully sucked into first air inlet, to improve the suction effect of range hood to oil fume.

The utility model discloses a half bridge type scrape suction mud machine equipped with centrifugal blower, this scrape suction mud machine includes the center support, and the center support top is provided with the bridge frame of horizontal, and the bridge frame end is provided with the drive mechanism, and sets up the rest grid strip combination under the bridge frame, and is provided with a plurality of suction mechanism on the rest grid strip combination, and a plurality of suction mechanism are arranged along the length direction of bridge frame and are connected on the mud discharge pipe, and the mud discharge pipe is connected with the suction device, and the scrape suction mud machine still includes centrifugal blower, and centrifugal blower sends high pressure gas into the suction port place of each suction mechanism through the air pipe, and the bottom of suction mechanism is provided with the inclined bracket plate, and the bracket plate pushes the sludge to the center support direction movement, and the suction port place of the sludge of closer center support, and the more compressed air of inhaled, and the high pressure air is inhaled through centrifugal blower at the suction port of scrape suction mud machine, makes it spouts the sludge, improves the mud water separation effect, and is convenient for scrape suction mud machine suction.

This application discloses a control method for a surface cleaning device. The surface cleaning device includes a floor brush with cleaning components and a suction system for removing dirt. The floor brush includes a housing, on which are a movable front scraper located in front of the cleaning components and a floor scraper located behind the cleaning components and in contact with the ground. When the floor brush moves forward, the front scraper moves upward away from the ground; when the floor brush moves backward, the front scraper moves downward and in contact with the ground. The method includes reducing the operating power of the suction system when the floor brush moves backward. In this application, when the floor brush moves backward, the front scraper contacts the ground, and together with the floor scraper in contact with the ground, the brush chamber and the ground form a relatively sealed space. Under the action of the front scraper, the floor scraper, and the suction airflow of the suction system, the resistance of the floor brush to the ground increases. At this time, reducing the operating power of the suction system can ensure the dirt removal effect of the surface cleaning device and reduce the operating resistance of the floor brush to the ground, thus ensuring the cleaning effect.

A hemp powder cake green skin removing production line, comprising a feeding hopper, a vibrating feeder, a Z-type elevator and a vibrating material distributing screen arranged in sequence, the vibrating feeder being arranged between the outlet of the lower end of the feeding hopper and the Z-type elevator; a buffer hopper and a scattering machine arranged in an up-down manner are installed at the outlet end of the Z-type elevator through a support frame, the discharge port of the lower end of the buffer hopper corresponding to the feeding port of the upper end of the scattering machine, the discharge port of the lower end of the scattering machine corresponding to the feeding port of the upper end of the vibrating material distributing screen, the vibrating material distributing screen being used for fully dispersing the material; a skin suction air chamber is arranged at the discharge end of the vibrating material distributing screen, the lower end of the skin suction air chamber being provided with a discharge port, the upper end of the skin suction air chamber being provided with a suction port, and a skin suction settler is arranged at one side of the skin suction air chamber, the feeding port of the skin suction settler being communicated with the suction port. The production line can reduce the number of crushing and grinding times in the processing of hemp seed protein powder, reduce the energy consumption of the equipment, and improve the yield of hemp seed protein powder.
