Embodiment Construction

[0011] Such as figure 1 As shown, a ring-shaped filter device for the production of dibutyl tin oxide includes a ring pipe 1, a plurality of suction filter heads 2 connected to the ring pipe, and a water outlet 3 arranged on the ring pipe. The water outlet 3 and the vacuum The container pipes are connected, and the connection angle of the suction filter head 2 is 45° along the stirring direction of the container and the tangent to the loop pipe. The loop pipe 1 and the suction filter head 2 are made of metal with anti-acid and alkali corrosion or surface anti-corrosion treatment Of metal. The suction filter head 2 is provided with a filter screen 7, the filter screen 7 is evenly distributed with water-permeable holes 6, the two ends of the suction filter head 2 are connected with protruding rings 5, and the filter screen 7 is fastened by a compact material 4. The filter screen 7 is a stainless steel filter screen or a synthetic fiber filter cloth.

Abstract

The invention relates to the field of filtering devices, in particular to an annular filtering device for dibutyltin oxide production. The annular filtering device for dibutyltin oxide production comprises an annular pipe, multiple suction filtration heads connected to the annular pipe and a water outlet formed in the annular pipe, wherein the water outlet is connected with a vacuumizing container pipeline, connecting angles of the suction filtration heads are included angles of 15-60 degrees formed by the stirring direction of a container and the tangent line of the annular pipe, and the annular pipe and the suction filtration heads are made from acid and alkaline corrosion preventing metal or metal subjected to surface corrosion preventing treatment. By the adoption of the annular filtering device for dibutyltin oxide production, liquid in dibutyltin oxide solids can be effectively and rapidly seperated in the dibutyltin oxide production, back flushing can be performed by utilizing gas or water to prevent filter screen blockage, and the effect of improving the production speed is obvious.

Description

Technical field [0001] The invention relates to the field of filter devices, in particular to a ring filter device for the production of dibutyl tin oxide. Background technique [0002] Dibutyltin oxide is an important intermediate of organotin products. Its production process is composed of multiple reactions and washing. Each reaction and washing process will produce an alkaline liquid containing salts. At present, the solid-liquid separation method used in the production process of dibutyltin oxide is the plastic tube insertion suction filtration method, that is, each solid-liquid separation process requires the operator to insert a special tubular filter device into the bottom of the reactor, and then pass through the vacuum container Carry out the method of suction filtration. This method is inconvenient to operate, has few suction filtration points and long solid-liquid separation time. Summary of the invention [0003] The purpose of the present invention is to provide a...
