Fig. 2 is another angle schematic of fig. 1.
Fig. 3 is a partial structural schematic view of fig. 2.
In the figure, the device comprises a main frame 1, a main frame 2, a motor 3, a driving shaft 4, a driven shaft 5, a chain wheel 6, a stainless steel pore plate 7, an installation base 8, a water outlet 9, a blanking port 10, a grid slag conveyor 51, a pin 61 and a filtering hole.
Detailed Description
Referring to fig. 1 to 3, the large flux mesh plate type fine grating device includes a main frame 1, a motor 2 and a driving shaft 3 installed at the top of the main frame 1, and a driven shaft 4 installed at the bottom of the main frame 1. The motor 2 is connected with the driving shaft 3. The main frame forms an included angle of 75 degrees with the ground.
The driving shaft 3 is connected with the driven shaft 4 through two parallel chain wheels 5.
Be equipped with a plurality of stainless steel orifice plates 6 between two sprocket 5, a plurality of stainless steel orifice plates 6 are along the profile align to grid of sprocket, and the both sides of stainless steel orifice plate 6 are all connected with the sprocket 5 of both sides through pin 51. Two pins 51 are provided on both sides of each stainless steel orifice plate 6.
The stainless steel pore plate 6 is provided with a plurality of filtering holes 61 which are arranged according to an L shape, and the aperture of each filtering hole 61 is 1 mm.
The main frame 1 is fixed to the ground by a mounting base 7.
The lower parts of the two sides of the main frame 1 are both provided with water outlets 8.
The top of the main frame 1 is provided with a downward blanking port 9, and the height of the blanking port 9 from the ground is not less than 750 mm.
A grid slag conveyor 10 is arranged below the blanking port 9.
The working principle of the utility model is as follows:
during the in-service use, the motor passes through driving shaft and driven shaft drive sprocket rotation, and the same direction rotation of stainless steel orifice plate is driven to the sprocket. The sewage is the side play of advancing outward, and when sewage passed through the stainless steel orifice plate, debris in the sewage can be intercepted outside. During the upward rotation of the stainless steel orifice plate, garbage in the sewage is brought to the blanking port and falls into the grid slag conveyor.
The utility model discloses a debris effect in the sewage is salvaged to the perforated plate form is more obvious, and the lump (bottle lid, cigarette end etc.), slice (plastic bag, leaf etc.), filiform (hair, fibre, rope etc.) are whole can be fished out. Under the condition that the discharge standard of a sewage treatment plant is increased day by day, the grating in the form of the porous plate can better protect the stable operation of subsequent treatment process units and prolong the service life of mechanical equipment. The sewage treatment plant which is improved by upgrading can be conveniently replaced by equipment.
The utility model has the advantages that:
1. the positive and negative sewage contact surface homoenergetic of stainless steel orifice plate is intake, has increased the overflow of sewage, is applicable to the sewage treatment plant who does not possess the extension more and carries the standard improvement project.
2. The water outlet of the grating is water outlet from two sides, and simultaneously has the advantages of large flow and good sealing performance, and sundries which are not fished out in sewage cannot enter a rear treatment unit. The fished sundries which do not smoothly fall off in the link of the feeding port can circulate outside along with the rotation of the stainless steel orifice plate.
3. The filter fineness is strong, and the aperture can accomplish 1mm at least, can intercept the multiple non-soluble pollutant that traditional fine grid can't be intercepted.
4. The cross section of the water passing is more than 2 times of that of the traditional grating, so that the occupied area can be saved, the equipment investment can be saved, and the operation energy consumption can be reduced under the same condition.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above, it will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, but that the invention may be embodied in other specific forms without departing from the spirit or essential characteristics of the invention.
