The specific embodiment
Big at present spouting plant dust-producing amount and can't collect characteristics, the utility model has been done following improvement: in order to collect the dust that spouting plant produces, spouting plant has been increased devices such as collecting plate 15, dust gathering arrester 16, last dust guiding groove 4, following dust guiding groove 10, sweep-up pipe 12, in addition improvement has been done in the sealing between original hopper, hopper and top board.
(1) improvement on the hopper: original hopper is the dead-beat hopper, now changes the dead-beat hopper into oblique feed hopper 1, as shown in Figure 1, 2.
During former pulp shooting machine charging, when rotor block 8 forwards between pressure relief opening 3 and the charging aperture 22, last pressure relief opening 3 can and charging aperture 22 connect, the part high pressure gas is known from experience from charging aperture 22 and is overflowed; At last pressure relief opening 3, down pressure relief opening 11 stops up or during rubber gasket sheet 6 wearing and tearing, gas can be between charging aperture 22, steel liner plate 7 and the rubber gasket sheet 6, overflow the generation dust between hopper and the top board 5.
The gradient of gradient at the bottom of the oblique bucket of oblique feed hopper 1 at the bottom of than former dead-beat hopper is big, and adds a charging baffle plate 20 above the charging aperture of oblique feed hopper 1, and it is shaped as half elliptic, and material is the thick steel plate of 30mm.During installation, the hopper top of charging baffle plate 20 tops and charging aperture 22 tops joins, and the bottom is positioned at charging aperture 22 outside 50mm and is the intersection of the position of 80mm apart from the vertical distance at the bottom of the oblique bucket, with the hopper full weld.When the mix height does not surpass the extreme lower position of charging baffle plate 20, form a semiclosed annular seal space between charging baffle plate 20 and hopper; When the mix height surpasses charging baffle plate 20 extreme lower positions, form a totally-enclosed annular seal space with hopper, collect dust.On vibrating motor 17 being installed at the bottom of the oblique bucket of hopper, to guarantee charging rate.At the hopper top drilling of oblique feed hopper 1 with the semiclosed annular seal space of charging baffle plate 20 formation; weld a dust leg 19 that φ 80mm length is 100mm; its installation position is in pulp shooting machine pressure relief opening direction; circular arc tangential line direction and along continuous straight runs along oblique feed hopper 1 are inclined upwardly 30 °; being beneficial to the collection of gas leakage and coarse granule that gas leakage is taken away falls back in the hopper; dust leg 19 links to each other with the negative pressure airduct 13 of sweep-up pipe 12 usefulness φ 100mm, is brought under the suction of dust at deduster that charging aperture produces and staticizes processing in the deduster.
(2) improvement that seals between hopper and pulp shooting machine top board: the sealing of former machine hopper and pulp shooting machine body is that a thick rubber tile of 5mm is pressed on the platen with press strip, and its sealing is poor, and is fragile.Now the charging aperture 22 with oblique feed hopper 1 is lengthened to 70mm, and at charging aperture 22 hopper seal receptacle 21 of joint weldering with hopper, shape is made with the steel plate that 3MM is thick as shown in Figure 3, width along the profile of charging aperture 22 to extending out 40mm.Make for the rubber tile of 40mm with thick, width suitable for reading along the profile of charging aperture 22 to extending out 30mm, end opening to the right-angled trapezium joint ring 2 that extends out 20mm, to increase elasticity and sealing, its shape as shown in Figure 4, it is filled weight behind the material by oblique feed hopper 1 and compresses and produce sealing, has effectively solved the sealing problem of oblique feed hopper 1 and top board 5.
(3) collecting plate: between pulp shooting machine top board 5 and oblique feed hopper, increase the collecting plate that the 3MM steel plate is done, structure as shown in Figure 5, collecting plate is installed on the top board 5 with the set bolt of the hopper shock-absorbing spring seat of eight M10.
The size of charging hole 23 is than the big 25mm of size of charging aperture 22, allows joint ring 2 be pressed between the hopper seal receptacle 21 on top board 5 and the oblique feed hopper 1.The suction port 24 of collecting plate 15 is than the last pressure relief opening 3 and the following pressure relief opening 11 outside 180mm of pulp shooting machine, and outside top board 5 outline lines, and the hole that to open a diameter directly over last pressure relief opening 3 and the following pressure relief opening 11 be 75mm is used for installing sweep-up pipe 12.Dust gathering arrester mounting groove 25 is the semi-circular groove of welding thick 2mm, φ 10mm on the outer of collecting plate 15, equally also welds identical shaped dust gathering arrester mounting groove on the lower platen 14 of pulp shooting machine body, is used for installing dust gathering arrester 16.Tracheae installing port 26 is holes of a φ 110mm, is the preformed hole that is used for installing tracheae.Between board adjusting bolt installing port 27 and the top board 5 certain clearance is arranged, when the deduster dust suction, guarantee the circulation of air in the dust gathering arrester 16, with extraneous air pressure, prevent that the dust gathering arrester inner and outer air pressure is unbalance flat by suction in the balance dust gathering arrester 16.
(4) dust guiding groove: contain sand and dust gas as being sprayed directly on on the dust gathering arrester 16 owing to what pulp shooting machine sprayed, time has been grown will be breakdown, and following pressure relief opening 11 in the bottom of dust gathering arrester 16 not quilt cover go in the dust gathering arrester, dust all spreads, therefore dust guiding groove 4 on installing at last pressure relief opening 3 places, prevent that dust gathering arrester 16 from being punctured by dusty gas and control the diffusion of dust in dust gathering arrester 16, its shape as shown in Figure 6.At following pressure relief opening 11 places a back cut diameter 220mm chord length being installed is 190mm, lower port diameter 150mm chord length is 130mm, height is the arc of 350mm, form dust guiding groove 10 down, the installation site of arc is that the plain farthest line and the pulp shooting machine body side angle of dust guiding groove 10 down is 15 °, with the angle of pulp shooting machine body horizontal direction be 41 °, its shape is as shown in Figure 7.Form a lift when dusty gas impinges upon its surface, make floating dust rise to enter in the dust gathering arrester 16 and be sucked away, oarse-grained dust dust guiding groove 10 under the action of gravity lower edge falls.Upper and lower dust guiding groove is separately fixed on the upper and lower pressing plate with the bolt of M12.
(5) dust gathering arrester: between top board 5 and the rotor block 8, compress sealing by rubber gasket sheet 6 and steel liner plate 7 between rotor block 8 and the lower platen 14.When rotor block 8 rotation, easily leak and produce dust and cause dust around rotor block 8, overflowing.Therefore around rotor block 8, increased a dust gathering arrester 16, dust gathering arrester 16 is to make with the thick transparent plastic sheet of 2mm, so that observe the leakage situation of pulp shooting machine dust, dust gathering arrester 16 rotates 8 one weeks of daughter, be installed on the dust gathering arrester mounting groove of lower platen 14 and collecting plate 15, tight with quick padlock, prevent overflowing of dust.
(6) sweep-up pipe: the dust that is used to collect oblique feed hopper 1 and dust gathering arrester 16 collections, as shown in Figure 8, the reducer pipe that sweep-up pipe 12 is mounted on the suction port 24, become φ 200mm by φ 150mm is made, in order to avoid oblique feed hopper, sweep-up pipe 12 outward-dipping θ=72 °, vertically upward,, link to each other with dust leg with the negative pressure airduct again at the burn-on steel pipe of φ 80mm, long 50mm of the relevant position of oblique feed hopper dust leg opening from the position of collecting plate 15 high 300mm.
Though embodiment of the present utility model has been described with reference to the drawings above, it will be understood by those skilled in the art that under the situation that does not break away from the utility model scope and spirit, can make various modifications and variations to the utility model.Therefore, should be appreciated that the above embodiments are not restrictions, but the illustrating of various aspects.
