A dross discharge apparatus for a magnetic filter, as shown in fig. 1 to 4, is installed below a scraping unit 4 of the magnetic filter, and includes: a scum discharge groove 51 in a long tubular shape, a spiral conveying rod 52 arranged along the central shaft of the scum discharge groove, a driving motor 53 in transmission connection with the spiral conveying rod 52 and a scum chute 54; the top of dross discharge tank 51 is the opening setting, and the opening position corresponds scraping device and sets up, and the both ends of auger delivery pole 52 are connected with the both ends board of dross discharge tank 51 through the bearing, and the one end bottom surface of dross discharge tank 51 is provided with the drain 511 that is linked together with dross chute 54. Through holes through which the screw conveyor 52 passes are provided in both end plates of the dross discharge chute 51, respectively.

In operation, as shown in fig. 3, when the magnet rod 12 moving back and forth in a lifting manner descends, the scrapers 42 of the scraping device 4 are closed to scrape off iron powder and dross adsorbed on the magnet rod 12, and the iron powder and dross slide down the inner inclined surfaces of the scrapers into the dross discharge chute 51 below, are discharged to the drain 511 at the outer end of the dross discharge chute 51 by the screw conveyor 52, are discharged to the outside along the dross chute 54, and are collected.

Preferably, the dross discharge groove 51 has a U-shaped cross section with an open top, so that the top opening of the dross discharge groove 51 is enlarged as much as possible, thereby facilitating better collection of the iron powder and dross scraped by the scraping device 4 and preventing the iron powder and dross from sliding to other positions and causing difficulty in cleaning.

Preferably, as shown in fig. 1, a screw conveyor extends to the outside of the dross discharge groove 51 and is provided with a driven wheel 56, and the driving motor 53 is provided with a driving wheel 55, which is connected with the driven wheel through a transmission belt or a transmission chain. In this embodiment, the driving motor 53 is a speed reduction motor.

Preferably, as shown in fig. 2, the drive motor 53 is synchronously connected to a plurality of driven wheels 56 of a row of dross discharge chutes arranged in parallel via the same belt or chain. The arrangement greatly improves the working efficiency of the device, simplifies the whole structure of the device and reduces the manufacturing cost of the device. In other embodiments, the plurality of scum discharging devices arranged in parallel can be divided into two groups, and the two groups of scum discharging devices are respectively driven by the two driving motors, so that the independent work of the two groups of scum discharging devices is ensured, and the two groups of scum discharging devices can conveniently work in a staggered manner to adapt to different working states of the scraping devices at corresponding positions.

Preferably, as shown in fig. 4, in order to increase the capacity of the dross discharge groove 51 and to enlarge the transfer distance, the dross discharge groove 51 is set to have a length greater than the width of the magnetic filter, and one end of the dross discharge groove 51 extends outward through one side case of the magnetic filter.

The upper portion of the fixing base is provided with an annular connecting portion 461 through which the horizontal rotation shaft passes, and the lower portion of the fixing base is a connecting leg 462 which is screwed with the side of the dross discharge groove 51.

Example 2

Because the iron powder obtained by the traditional magnetic filter contains a large amount of impurities and oil stains, the iron powder is difficult to be used as fuel oil, and because an effective treatment means is lacked or the treatment cost is high, the iron powder can only be used as a sintering raw material or directly buried, so that the environmental pollution is caused.

In order to improve the utilization rate of the iron powder with scum stains obtained by filtering and improve the cleanliness of the collected iron powder, on the basis of embodiment 1, the scum discharging device provided by the embodiment is provided with the following settings:

as shown in fig. 5-6, in the present embodiment, a spray pipe 58 for spraying oil stain cleaning liquid is disposed on an inner side wall of the scum discharge tank 51 along a length direction, a liquid leakage hole 512 is disposed on a bottom wall of the scum discharge tank 51, a layer of stain collection tank 59 is additionally disposed on an outer periphery of the scum discharge tank, and a stain outlet 591 is disposed at one end of the stain collection tank.

In operation, after the dirty iron powder mixture slides into the scum discharge tank 51, the oil stain cleaning solution sprayed by the spray pipe 58 is fully stirred with the iron powder mixture under the action of the screw conveying rod, so that the oil stains therein are fully dissolved in the cleaning solution and flow to the lower stain collecting tank 59 along the liquid leakage hole 512 at the bottom of the scum discharge tank 51, and are discharged from the stain outlet 591; and the washed fine iron is collected from the dross chute 54 by the action of the auger.

In a further preferred embodiment, in order to improve the washing and sewage discharging efficiency, the dross discharging groove 51 is inclined with one end of the dross chute 54 connected thereto being an upper end and the other end being a lower end, and the stain outlet 591 of the stain collection tank is provided near the lower end of the dross discharging groove 51. The cleaning liquid in the dross discharge groove can flow to the dross discharge port 591 more quickly due to the inclined arrangement of the dross discharge groove 51, so that the probability that the sewage is brought into the dross chute 54 by the spiral conveying rod is greatly reduced, and the cleanliness of the iron powder is further improved. The iron powder obtained by the equipment has wider application and higher utilization rate.

The above-described embodiments of the apparatus are merely illustrative, and the units described as separate parts may or may not be physically separate, and parts displayed as units may or may not be physical units, may be located in one place, or may be distributed on a plurality of network units. Some or all of the modules may be selected according to actual needs to achieve the purpose of the solution of the present embodiment.
