The invention has high separation efficiency, low tower body height, and can prevent liquid dripping from the tray.

The invention discloses a novel grouting anchor rod which comprises a hollow anchor rod body, a drill bit arranged at the front end of the hollow anchor rod body, a slurry stopping plug, an arch-shaped support plate, a fastening nut and an anchoring connection sleeve, wherein the slurry stopping plug, the arch-shaped support plate and the fastening nut are sequentially arranged at the rear end of the hollow anchor rod body, and the anchoring connection sleeve is arranged in the middle of the hollow anchor rod body. The anchoring connection sleeve comprises a cylindrical sleeving cylinder and three anchor bars hinged to the cylindrical sleeving cylinder and uniformly distributed on the outer circumference of the cylindrical sleeving cylinder; grooves sunken towards the axis direction of the cylindrical sleeving cylinder are formed in the cylindrical sleeving cylinder and are matched with the anchor bars; one ends of the anchor bars are hinged to the cylindrical sleeving cylinder through hinging shafts inside the grooves; grouting holes communicating with a hollow core part of the hollow anchor rod body are formed in the grooves; and the hollow anchor rod body is cut into two segments through the cylindrical sleeving cylinder and is connected and fixed in a threaded connection mode. The novel grouting anchor rod is reasonable in structural design and convenient and easy to use, and grasping force of cement columns after slurry solidification can be increased.

The invention relates to a wetting type water spray windscreen wiper. A windscreen wiper buckle of the windscreen wiper is installed on flow deflectors and used for being connected with a windscreen wiper support. A flow guide channel is formed in each flow deflector. A plurality of spray head bodies are pre-embedded in two sides of each flow guide channel. A circular arc-shaped opening groove is formed in one side, close to a windscreen, of each spray head body and extends along the direction of the flow deflectors. Two flow guide pipes are expanded by a water pipe through a reducer tee connector and are respectively communicated with the flow guide channels in the flow deflectors on two sides of the windscreen wiper buckle through pre-embedded connecting pieces of the flow deflectors. The wetting type water spray windscreen wiper can ensure that rubber windscreen wiper strips are provided with sufficient moisture when scrapping the windscreen and can be well attached to the surface of the windscreen, and therefore frictional resistance between the windscreen wiper strips and the windscreen is reduced, frictional noise is lowered, motor load is reduced, water waves and linear residue can not be generated, and the windscreen is clean.

The invention discloses an aerodynamic energizer which comprises a rack, a drive motor, a dynamic energizing plate, a static energizing plate and a gas exhausting pipe. The dynamic energizing plate can be installed on the rack in a rotatable mode. The static energizing plate is fixed above the frame and arranged above the dynamic energizing plate in a piled mode. An inner spiral channel and an outer spiral channel are arranged on the upper surface of the dynamic energizing plate in parallel. The static energizing plate is provided with a locking ring which is tightly arranged on the outer rim of the outer spiral channel in a sleeved mode. The static energizing plate is provided with an air inlet and an air outlet. The air exhausting pipe is fixed below the static energizing plate. The air exhausting pipe is provided with an ascending segment and a descending segment. The lower end of the ascending segment is connected with the air outlet in a communicated mode. The lower end of the descending segment is closed and a side wall of the descending segment is provided with an ejecting opening which is arranged above the lower end portion of the descending segment. An output shaft of the drive motor is fixedly connected with the lower bottom face of the dynamic energizing plate. The aerodynamic energizer has the advantages of being large in compression amount and high in compression speed. Thus, ejecting force of an ejecting opening is strong and will not weaken.

The invention discloses a dustproof filtration device for a chimney. The dustproof filtration device comprises at least two connection rods, wherein at least three vertical troughs are arranged between the two connection rods; a plurality of water stopping sheets are arranged on the inner wall of each trough and are tightly connected with one another; the water stopping sheets on two adjacent troughs are staggered from each other; a water feeding pipe penetrates through the centers of the troughs; at least three groups of vertical sprayers are arranged on the water feeding pipe; each group of sprayers are arranged above the corresponding water stopping sheets; a plurality of atomized water sprayers which are uniformly distributed along the water feeding pipe are arranged in each group of sprayers; the atomized water sprayers in two adjacent sprayers are staggered from each other; a water outlet is formed in the bottom of each trough; a downwards extending water discharging pipe is inserted into each water outlet; the bottom end of the water discharging pipe in the trough positioned on the upper side is close to the water outlet in the lower water trough; and the water discharging pipe in the bottommost trough is connected with a filtration pool. The dustproof filtration device has the advantages of simple structure, energy conservation, environment friendliness and wide application range.

The invention is applicable to the field of dishwashers, and discloses a dishwasher self-cleaning water flow system and a dishwasher, wherein the dishwasher self-cleaning water flow system includes a water cup with a filter chamber and a water inlet chamber, a water suction pipe and a water outlet pipe. The washing pump, the water diversion valve chamber cover covering the water inlet chamber, the plane filter covering the filter chamber, the cylinder filter installed in the filter chamber and the cylindrical filter pierced and extended from the plane filter The filter cup in the filter, the water suction pipe is connected to the filter chamber, the outlet pipe is connected to the water inlet chamber, and the water diversion valve chamber cover includes a cover covering the water inlet chamber and extending from the cover to pass through the filter chamber. The water spray pipe is located inside and beside the cylindrical filter, and the water spray pipe is provided with several water spray holes facing the cylindrical filter.
