SU10161A1 - Pumping device for thick liquids - Google Patents

Description

The invention relates to a pump for thick liquids in which such, entering the receiving bucket, is then fed into the cylinder by means of an auger, and is squeezed out of the cylinder by a piston having a bevelled end.

In FIG. 1 shows a longitudinal section of the pump; FIG. 2- front view of the pump; FIG. 3 - view of the pump from above; FIG. 4 is a longitudinal section of a modified pumping device; FIG. 5 and 6 are a cross-section and a view from above of this last device.

In the cylinder 1 (Fig. 1), the piston 2 moves, the lower part of which is bevelled to facilitate the sliding of the mass and emptying the cylinder. Under the upper piston, there is a second piston 4, which also has a bevel on top, corresponding to the upper bevel of the upper piston; the slope of the bevel is facing the exit window 11. A pin 6 is mounted on the lower piston, which runs along the slit in the cylinder wall and does not allow the lower piston to rotate also in that direction: the bevel direction. The lower piston is supported by a spring 5 installed on the lifting disc 7, the voltage of which

adjusted by screw 8; in accordance with the density of the feed mass. To inspect the spring, lower piston and cylinder, the lower part of cylinder 9 is unscrewed and the disk 7, spring 5 and piston D are removed. In the wall of the cylinder there is a window P „connected to the pressure pipe 12. The pump is fixed on the frame 19 by means of the support legs 18 (Fig. 2); Brackets 20 are installed on the same frame, on which gear shaft 21 with gear 23 and working pulley 22 (Fig. 1 and 2) and crankshaft 24 with gear gear 25 coupled with gear 23 are mounted in bearings 26 and knee shaft 24 is coupled with The connecting rod 3, driving the piston 2. At the end of the crankshaft, shaft 24 (FIG. 3), a transmission pulley 27 is mounted, driving the rotation, using a belt drive, a pulley 27a mounted on the shaft 41. The shaft is packed in bearings 29, mounted on the bracket 28, and mounted on it. Eccentric 31 and conical shetern 30, linked and a second bevel gear zoo, fitted on a screw shaft 39 installed at one end -to wall

oats 38, and others in the body of the cylinder 13..

A bucket 38 serves to feed the mass.

: a concave lattice 34 reinforced in it, above which is located a second swinging sieve 35 ,, which has a band between the strips of the lattice 34 (Fig. 3); The zing end of the grille 35 is equipped with hinges 36, and the other end is coupled to the lever, driven by the cam 31, so

that this end of the lattice is driven in a vertical swing. At the bottom of the bucket there is a screw 39 (a screw screw) and a visor 17 above it. Between the bucket and cylinder 1 a receiving cylinder 13 is placed, connected ush, yis to cylinder 1 through hole 10, and with a LJOM-hole 16 with a latch. In the receiving cylinder 13 there is a metal empty float 14 with a rod 15, which is adjusted by nuts 12 (Fig. 1). The bottom of the cylinder 13 can be unscrewed and there is a recess 23. The mass to be supplied falls into the bucket 38, where, due to the swing of the grid 35, it loosens and passes through the grids 35 and 34 to the bottom of the bucket, from where the auger 39 is fed through the window 1ba in the receiving cylinder 13; the visor 17 contributes to the formation of a screw head on the mass to move it into the cylinder. When mass enters the cylinder 13, the float 14 rises under its pressure. When, as a result of the upward movement of the piston 2, the window 10 opens, the mass under the influence of the pressure of the screw 39 and the pressure of the float 14 moves from the receiving cylinder 13 into the cylinder I until, when the piston moves back down, the piston 2 again does not close the window 2; upon further downward movement of the piston through the mass of chDavit to the lower piston 4, which on the spring moves downwards and opens a window 11, through which mass and is squeezed out into the discharge pipe. Get to your bottom position and displace the whole mass.

the piston 2 simultaneously closes the window 11; upon further movement of the piston 2 upwards, simultaneously with it under the pressure of the spring 5, the piston 4 rises and closes the window 11, as a result of which mass return into the cylinder becomes impossible. Then, rising above, the piston 2 reopens the receiving window 10, through which a new portion of mass, already prepared in the receiving cylinder 13, enters, and then the described process repeats.

In a modified pumping device (Fig. 4-6), cylinder 1 is horizontal and equipped, as in the above described device, with pistons 2 and 4 with beveled ends, of which piston 4 rests on spring 5, the tension of which is adjusted by screw 8, rie-shifting the disk 7, and the piston 2 is set in motion through the connecting rod 3 by the crankshaft 24, the gears 25 and 23 rotated and the working pulley 22. The cylinder is provided with windows 10 and 11 and a pressure pipe 12. Unlike the first mass receiving device, there is an open bucket 43, in which a rotating stand 45 with a handle 46 and a rotary flap 44 blocking the inlet 10 is installed. the same as the above, where it is used for less thick masses that do not require the use of special devices for introducing them into a cilium.

The subject of the patent.

1. A pumping device for thick liquids, characterized by the use of a bucket 38 for receiving liquid (Fig. 1-3), equipped with a fixed grating 34, a swinging grating 35 and a screw 39 for supplying liquid to the receiving cylinder 13, equipped with a float 14 and communicating through the window 10 with the vertical pump cylinder 1 communicating in turn.

through the window 11 with the pressure pipe 12 and enclosing the reciprocating working piston 2, bevelled from the bottom, and the beveled piston 4 from above, guided by the pin 6, supported by the spring 5 adjusted by the screw 8 and intended for closing the window 11, with The inlet port to the cylinder 13, which is closed from below with a plug 40 - with a recess 23, is controlled by a valve 16, and the end of the screw 39 is closed by a visor 17.

2. A modification of the device described in clause 1, characterized by its use, instead of the vertical cylinder 1, horizontal cylinder 1 (Fig. 4-6), whose inlet 10 is covered by the adjusting swivel shield 44 and communicates directly with a simple open bucket 43.
