As a kind of preferred scheme, pin-and-hole is offered in the installing arm, the scraper is provided with and matches with the pin-and-hole
The alignment pin of conjunction.
Used as a kind of preferred scheme, the both sides of the conveyer belt are inclined upwardly, and angle of inclination is 10°-30°。
Used as a kind of preferred scheme, the liquor inlet is located at the top of filtrate (liquid, and the air inlet is located at feed liquid
The top of import.
As a result of above-mentioned technical proposal, the beneficial effects of the utility model are：
Existing pressure filter feed liquid directly enters filter pocket after Filter Press by filter tip, easily occur material splash and
The problems such as leakage, while blowing to filter cake when drying up, also pass through filter tip and enter filter pocket, easily produce a large amount of gases, it is remaining
Material expulsion events are even more serious.The filter press that the utility model is related to, during filter pressing, filtrate is directly dark by what is be interconnected
Discharge orifice, reaches filtrate (liquid, and by closed conduct filtrate tanks are entered.When drying filter cake, abnormal smells from the patient also enters closed conduct.
Solve the pollution problem that filter pressing workshop is caused because of steam and abnormal smells from the patient.
Meanwhile, material cake conveyer device is provided with, the filter cake after filter pressing is delivered to into material cake groove.Conveyer belt both sides incline, and keep away
Exempt to expect that cake is scattered.Because the filter cake Jing after wind contains residual moisture, affect transport, be provided with scraper, it is ensured that filter cake completely into
Material cake groove.
The liquor inlet is located at the top of filtrate (liquid, and the air inlet is located at the top of liquor inlet.Be conducive to material
Liquid enters filter frame and filtrate flows out filter frame, accelerates efficiency of press filtering.
