Filter pressing spraying system

Abstract

The invention relates to a filter pressing spraying system. The filter pressing spraying system comprises a plurality of pairs of pressing plates of a filter press and further comprises a control unit, wherein a filter bag for filtering a reaction product is arranged between each pair of the pressing plates; a first channel through which washing liquid can flow is arranged on one side of each pair of the pressing plates; a plurality of spraying holes are horizontally formed in the middle range of at least one pressing plate; the washing liquid, which flows through the first channels, is used for washing the products in the filter bags from top to bottom; supplementing liquid flowing through the plurality of spraying holes is sprayed to the products from the middle range to be collected with the washing liquid; and the control unit is used for controlling the flow of the liquid passing through the first channels and the plurality of spraying holes. The filter pressing spraying system can work conveniently and is simple to operate; and an antioxidant can be added in a washing process and a full-automatic system control can be realized.

Description

technical field [0001] The invention relates to the field of filter press machinery, in particular to a filter press spray system. Background technique [0002] The filter press is a kind of mechanical equipment that uses a special filter medium to exert a certain pressure on the object to make the liquid dialysis out. The filter press has a wide range of applications, such as medicine, chemical industry, standard parts, pharmaceuticals, metallurgy, Environmental protection industries such as non-standard screws, dyes, food, air manufacturing, ceramics, oil refining, and sewage treatment can all be well utilized. [0003] Especially in the application of chemical industry, the conventional raw materials for the industrial production of cobaltous hydroxide are sodium hydroxide and cobaltous chloride. After the reaction of sodium hydroxide and cobaltous chloride, cobaltous hydroxide and sodium chloride will be generated. In order to obtain a battery The cobaltous hydroxide of...

Problems solved by technology

The first channel and the spray hole are set, when the first channel is fed with the antioxidant washing liquid, the spray hole can continue to feed the antioxidant replenishment liquid to the product at the same time, so that the concentration of the antioxidant washing liquid is the same as that prepared before. When the concentration is the same, and the spray hole is set in the middle range of the pressure plate, during the washing process, it is beneficial to solve the cobaltous hydroxide product in the filter bag from top to bottom when the antioxidant washing liquid is washed. After washing for a period of time, As a result, the concentration of the subsequent antioxidant washing solution is getting lower and lower, so that it cannot achieve a good separation and purification effect
