Abstract

The utility model discloses a hydraulic injector. A horn-shaped pipe (3) is arranged at a bellmouthing element (1) and on the inner wall of a slurry outlet pipe (2). The pipe (3) is generally made of ceramic materials, thereby improving the intensity of the inner wall and reducing abrasion damage. The utility model only needs to replace the horn-shaped pipe (3) without replacing the bellmouthing element (1) and the slurry outlet pipe (2).

Description

Vacuum Pumps

Technical field

The utility model relates to the haulage device field,, one of visual plant during especially hydraulic(-ash) sluicing and stone coal measures are united.

Background technique

The ash bucket that Vacuum Pumps mainly is used in thermal power plant deduster air preheater economizer directly is mixed into wet ash with dry ash and carries out the equipment that short distance is carried, its grey water mixer that is otherwise known as simultaneously down and under the grey storehouse.Existing Vacuum Pumps pulp pipeline adopts cast inblock more, be the horn mouth state, because when the slurry that mixes with water of dry ash advances and the friction at horn mouth pulp pipeline place very big, inwall is easy to wearing and tearing, need often to repair, breakage then needs to change whole pulp pipeline, has caused huge waste.

Summary of the invention

Summary of the invention purpose of the present utility model is to overcome above shortcoming, strengthens the abrasion resistance of inwall, need not to change the whole piece pipeline during replacing.The technological method that adopts: lined ceramics pipeline on the inner-walls of duct of pulp pipeline, adopt binding agent the horn shape earthenware duct to be attached on the inwall of horn mouth (1) and pulp pipeline (2) and get final product, saved material greatly.

Description of drawings

Fig. 2 is the utility model buck mixer structure schematic representation.

Embodiment

At the interior wall liner one horn shape earthenware duct (3) of horn mouth (1), adopt binding agent that the horn shape earthenware duct is attached on the inwall of horn mouth (1) and pulp pipeline (2) with pulp pipeline (2).

Claims (2)

1. Vacuum Pumps comprises horn mouth (1), pulp pipeline (2), it is characterized in that: described horn mouth (1) and pulp pipeline (2) inwall are lined with a horn shape pipeline (3).

2. Vacuum Pumps according to claim 1 is characterized in that: described horn shape pipeline is a stupalith.
