Detailed Description

The following describes the embodiments of the present invention in further detail with reference to the accompanying drawings.

Can know by fig. 1 to 5, electroplating effluent preprocessing device, which comprises a

tank body

1, 1 bottom of the jar body is equipped with a plurality of supporting

legs

12, 1 inside diaphragm 2 that is equipped with of the jar body, diaphragm 2 below is separated into filter chamber 3 and is collected chamber 4, the proportion of taking up of collecting chamber 4 is less than the proportion of taking up of

filter chamber

3, 3 internal rotations in filter chamber are provided with baffle 5, first through-hole 6 and second through-hole 7 have been seted up on the diaphragm 2, chamber 4 is collected in first through-hole 6 and second through-hole 7 through pipeline 8 intercommunication, 1 one side of the jar body is provided with water inlet 9 and the inlet pipe 13 of

intercommunication filter chamber

3, 1 opposite side of the jar body is equipped with the delivery port 10 that the chamber 4 was collected in the intercommunication, first through-hole 6 and second through-hole 7 department are provided with filter screen 11.

When the utility model is used in a concrete way,

in getting into filter chamber 3 with electroplating effluent from water inlet 9, delivery port 10 intercommunication subsequent process pipeline 8, other article that the filtration process need use drop into filter chamber 3 from inlet pipe 13 in, baffle 5 rotates and makes one of them in operating condition of first through-hole 6 or second through-hole 7, and another is in standby state, and electroplating effluent gets into after filtering through the filter screen 11 of this position and collects in the chamber 4, then discharges from delivery port 10.

It has more impurity to lead to the passing rate of filter screen 11 to descend by a wide margin to adhere to on the filter screen 11 in operating condition, rotating baffle 5 for filter screen 11 under the standby condition gets into operating condition, and operating condition's filter screen 11 switches to standby condition, and this time this filter screen 11 department does not have the existence of electroplating effluent, can take out filter screen 11 from jar body 1 and clear up, resumes the normal position once more after the clearance is accomplished, is in standby condition, so that accomplish next switching.

In order to facilitate getting of filter screen 11 and put, seted up fixed slot 14 on diaphragm 2, the fixed slot 14 outer end passes jar body 1 lateral wall, and filter screen 11 is placed in fixed slot 14, and fixed slot 14 and filter screen 11 are fan-shaped, and the quick of the filter screen 11 of being convenient for is got and is put, and filter screen 11 outer end size is greater than fixed slot 14 outer end size, is convenient for fix a position filter screen 11 in fixed slot 14.

Be equipped with the baffle between filter chamber 3 and the collection chamber 4, the baffle is 90 jiaos, it is in less space to collect chamber 4, baffle 5 and 3 wall sliding seal of filter chamber, the turned angle of baffle 5 is 90, baffle 5 is cut apart filter chamber 3, baffle 5 one side can communicate with water inlet 9 all the time, baffle 5 rotates the back, first through-hole 6 or second through-hole 7 are located the both sides of baffle 5 respectively, realize the state of single filter screen 11 work, 1 bottom of the jar body is fixed with drive baffle 5 pivoted motor 15.
