Detailed Description

The present invention will be described in further detail with reference to specific examples.

Example (b):

as shown in fig. 1, the utility model discloses a filter equipment for getting rid of carbon impurity in gold-bearing solution, including knot formula filter funnel 1, locate knot formula filter funnel 1 down the precipitation pipeline 2 of export, locate valve 21 and the filter component (first filter component 3a or second filter component 3 b) on the precipitation pipeline 2 and locate the filtrating jar 4 of 2 lower part exports of precipitation pipeline, filtrating jar 4 has the side mouth 41 of connecting vacuum pumping system, the bottom of filtrating jar 4 is equipped with leakage fluid dram 42, is equipped with first filter membrane 11 in the knot formula filter funnel 1. The button type filtering funnel 1 is a filtering container with a larger inner diameter, the whole device is a suction filtering device, a side port 41 is used for air suction, a filtrate tank 4 is used for storing a gold-containing solution after filtering, a liquid discharge port 42 is used for sending the gold-containing solution after filtering to a next processing device, a first filtering film 11 can carry out first filtering on carbon impurities with larger particles, and a filtering component carries out second filtering on finer impurities, so that the carbon removal requirement of the gold-containing solution is met, and the problem of pipeline blockage is solved.

The filter assembly includes a second filter membrane and a perforated plate. The perforated plate is used as the support of the second filter membrane near the air suction side, so that the second filter membrane is prevented from being damaged under the action of a strong pressure difference and cannot play a role in filtering.

As shown in fig. 1, the down-flow pipe 2 is provided with two branches respectively connected to the filtrate tank 4, and each branch is provided with a branch valve and a filter assembly. The first filter assembly 3a and the second filter assembly 3b are mutually standby and work alternately. The specific operation mode is as follows: the first branch valve 23a is opened, the second branch valve 23b is closed, and the solution is filtered by the first filter component 3a and then enters the filtrate tank 4 with the help of air suction; when the second filter membrane of the first filter component 3a is adsorbed and saturated, the first branch valve 23a is closed, the second branch valve 23b is opened, the second filter component 3b continues to carry out filtration, and the first filter component 3a is replaced by the second filter membrane; the second filter membrane of the second filter component 3b is immediately cut back to the first filter component 3a for filtration after being adsorbed and saturated, and the pause time is saved.

As shown in fig. 2, the button-type filter hopper 1 is provided with a fixed cover 12 and an openable movable cover 13, when the movable cover 13 is closed, the button-type filter hopper 1 is of a closed structure, the fixed cover 12 is provided with an exhaust pipe 5 connected with an exhaust mechanism, and the exhaust pipe 5 is provided with a manual valve 51. The gold-containing solution filtered by the device is generally aqua regia matrix, and strong corrosive acid mist is easily volatilized, so that the button type filtering funnel 1 cannot be in an open state during filtering treatment. After the liquid is added, the volatilized acid gas needs to be sucked away by the exhaust pipe 5 so as to avoid damaging the health of workers.

As shown in fig. 1 and 2, the movable lid 13 is rotatably connected to the fixed lid 12, and a handle 131 is provided on an outer surface of the movable lid 13. The movable cover 13 can be rotated to be opened by using the handle 131, and the operation is convenient.

As shown in fig. 1, the button-type filter 1 is fixed on a high-level bracket 6, and an operation step 61 is provided on one side of the high-level bracket 6. In order to make the filtrate flow only in one direction, the button-type filter hopper 1 must be higher than other pipeline parts, so that the button-type filter hopper needs to be arranged at the top end of the high-level bracket 6. In order to conveniently add liquid to the buckle type filter funnel 1, open and close the movable cover 13 and operate the manual valve 51 by workers, one side of the high-position platform 6 is provided with an operation step 61 for treading, so that the workers can reach high positions.

What has been described above is merely some embodiments of the present invention. For those skilled in the art, without departing from the inventive concept, several modifications and improvements can be made, which all fall within the scope of the invention.
