It should be mentioned that the middle channel is a U-shaped structure formed between the pool 2 and the floating object collecting pool 11, and the distance from the U-shaped bottom of the U-shaped structure to the working water surface gradually increases from the pool side to the floating object collecting pool side, as shown in fig. 4, after the floating objects enter the floating object collecting pool 11 from the pool 2, the problem of stacking of the floating objects easily occurs, and if there is no inclined U-shaped bottom, the stacked floating objects can easily enter the pool 2, so that the efficiency of removing impurities is affected.

Referring to fig. 5, the side wall of the notch is provided with a V-shaped mounting groove, the arresting plate is provided with a V-shaped mounting end matched with the V-shaped mounting groove, and the V-shaped mounting groove prevents the whole arresting plate from being separated from the end head easily.

Referring back to fig. 4, the bottom of floater collecting pit 11 is hopper-shaped, and the bottom of hopper-shaped floater collecting pit is connected in square buffer box 14 through first pipeline 13, buffer box includes upper left buffer cavity 14a and lower right buffer cavity 14b, be provided with the filter screen 15 that the slope was arranged between upper left buffer cavity and the lower right buffer cavity, the lower right buffer cavity passes through second pipeline 16 and connects in the shower nozzle water pump. The water of floater collecting pit 11 can be by cyclic utilization to shower nozzle department, can reduce the water consumption of whole equipment, and through square buffering box, can avoid directly pumping the water of floater collecting pit to block up because of the impurity problem. This buffer box body can install on ground, need be at first piping erection elevator pump this moment, and for reducing the energy consumption, square buffer box body is located the right side below of floater collecting pit. The structure can convey water of the floating collecting pool to the buffer box body without power, and the energy consumption is reduced. Because the bottom of the floating object collecting tank is funnel-shaped, a plastic net can be arranged at the top of the funnel-shaped position to intercept the floating objects with larger sizes from entering the first pipeline 13.

In fig. 4, a T-shaped water supply system connecting pipe 17 is arranged at the input end of the nozzle water pump, and a first interface of the T-shaped water supply system connecting pipe 17 is connected to a second pipeline and a second interface is connected to a municipal water supply network. This T shape water supply system connecting pipe lets the shower nozzle can utilize municipal pipe network to carry out the moisturizing or supply water circulation temporarily, and through first interface connection to buffer box, when the guarantee system circulation, the work of system is more reliable and stable.

Referring to fig. 4, in the hydraulic and pneumatic scrap steel crusher dust and impurity removing device, the spray head is flush with the working water surface. The surface that the rivers that the shower nozzle spun can directly propelling movement pond forms a rivers that move towards the pond rear side, and the floater of being convenient for is quick, the high efficiency removes the rear side in pond.

It should be noted that, referring to fig. 6-9, the blocking plate 12 is provided with an adjusting groove 12a along the length direction, the adjusting groove can be provided with an adjusting rod, the front and rear groove walls of the adjusting groove are provided with an adjusting interlayer 12b (see fig. 7-8) having the same length as the adjusting groove, the bottom of the adjusting groove is provided with a plurality of posture adjusting rod mounting holes 12c arranged along the length direction of the blocking plate, for example, six posture adjusting rod mounting holes are arranged at equal intervals, correspondingly, six posture adjusting rods are arranged, a blocking plate posture adjusting rod 12 'is arranged in the adjusting groove of the blocking plate, the rod body of the blocking plate posture adjusting rod is provided with a fixing ear 12 a' capable of entering the adjusting interlayer to suspend the blocking plate in the middle channel, and when the blocking plate rotates 90 degrees, the fixing ear is parallel to the adjusting groove to enable the blocking plate to descend to the blocking plate mounting groove arranged at the bottom of the middle channel, the lower part of the barrier plate posture adjusting rod enters a fixing hole formed in the bottom of the middle channel after passing through the posture adjusting rod mounting hole, and the posture adjusting rod mounting hole is of a cylindrical structure. When lifting the arresting plate and letting the arresting plate be higher than the working water surface, can let form a clearance and supply water through between the bottom of arresting plate and the bottom of intermediate channel (the unable both way around floater in pond and floater collecting pit this moment, both can guarantee that the floater collecting pit can not appear the floater when carrying out the floater clearance and enter into the problem in pond, the rivers of two cell bodies around this moment can flow as usual, do not influence equipment and remove dust), the arresting plate can articulate the fixed ear at arresting plate gesture adjusting rod.

Referring to fig. 10, the square buffer box 14 is provided with a buffer mechanism 18 facing the water inlet of the buffer box, and the buffer mechanism comprises: a vertical fixing plate 18a provided to the buffer tank; a horizontal fixing plate 18b provided to the vertical fixing plate; a buffer spring 18c provided at the left end of the horizontal fixing plate; and a buffer operating plate 18d installed at a free end of the buffer spring and facing an inlet of the buffer housing. Because the direct impact plate-shaped filter screen of water that 11 water deliveries of floater collecting pit come can let the great filter screen of breadth take place to warp, and then influence the filter screen and take place to drop or appear the clearance at the contact jaw of internal tip of baffle-box and let impurity enter into under the right buffer chamber 14b, and then appear blockking up the work of second pipeline 16 or influence water pump, more importantly, through this buffer gear, can avoid forming the rivers that circle round in the baffle-box. The top of the buffer water tank is provided with an overhaul and cleaning port, the overhaul and cleaning port is provided with a sealing cover through a flange structure, and the sealing cover is provided with a sealing ring.

In addition, can install bubble generating device in arc transport structure section 3 below, through arranging a bubble generating device in the pond, can upwards disturb range upon range of steel scrap metal to let the floatable rubbish that is located the steel scrap clearance float, if lack the disturbance bubble, be located the steel scrap range upon range of clearance such as foamed plastic then can't float, this is very unfavorable for the clearance of impurity, and more importantly, can be to the more swift clearance of the dust on steel scrap surface through bubble generating device.

The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way.
