The purpose of this utility model promptly provides a kind of solid-liquid separator, and it is without motor and back purge system, designs simplification, and the efficient height, price is low, and is easy to maintenance.

For reaching this purpose, the technical solution of the utility model is as follows: a kind of solid-liquid separator, it is characterized in that: shell 4 upper outside are connected with solid-liquid inlet connection 1, be provided with outer tube 2 in the shell 4, be provided with outlet pipe 3 in the outer tube 2,45 ° of inclined holes 11 and square hole 12 are arranged on the outer tube 2, one end of end socket 5 is connected with the gap location and the lower edge of square hole 12, the other end of end socket 5 is connected with shell 4, outer tube 2 feeds and reclaims chamber 13, reclaim in the chamber 13 and be provided with guide holder 7, three back-up block 8 support guide seats 7 that become 120 degree angles reclaim chamber 13 and communicate with solid outlet adapter 10, and outer tube 2 and 13 of chambers of recovery are connected to blast pipe 6, reclaim chamber 13 by end socket 9 sealings, 3 of shell 4 and outlet pipes are connected by last lower flange 14.

After adopting such scheme,, therefore saved the time of installing with maintenance because the utility model has been cancelled rotational components; Do not establish back purge system because of the utility model again, so do not need expensive spare part, and the utility model do not have when using and gets stuck, thus also with regard to do not need spare unit, total cost to equal same disposal ability existing separator 60%, price is low; In addition, the utility model efficient height, separating effect is obvious:

Contrast great in 7.0 gram per centimeters ³The solid particle separating effect reach 99.99% (diameter is greater than 80 μ m), as copper foam, steel foam, iron powder, lead powder foam etc.

Contrast great in 2.8 gram per centimeters ³The solid particle separating effect reach (diameter is greater than 80 μ m) more than 95%, as lime stone, the thin foam of glass etc.

Contrast great in 1.5 gram per centimeters ³The solid particle separating effect reach (diameter is greater than 80 μ m) more than 75%, as aluminium foam, concrete etc.

For little also can the separating of particle, if adopt double separating effect also fine.

For good greater than the particle separation effect spy of 80 μ m.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is a structure chart of the present utility model.

Fig. 2 is a vertical view of the present utility model.
