Detailed Description

For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

As shown in figures 1-2, the zinc dross hopper weighing device comprises a hopper 1, an adjustable connecting rod 2, an anchoring point 3 and a platform scale 4.

Hopper 1 is that the steel sheet welding or whole casting form, and hopper 1 opening up, the bottom is level and smooth, and the side inwards inclines. Four corners of the hopper 1 are respectively provided with a hanging lug 11 and a lifting lug 12. The hanging lug 11 is formed by processing a steel plate and is vertically welded outside the side surface of the hopper 1, and the tail end of the hanging lug 11 is provided with a round hole 112. The lifting lug 12 is a barb formed by processing a steel plate and is vertically welded outside the side surface of the hopper 1. The diameter of the circular hole 112 at the end of the hanging lug 11 is larger than the diameter of the pin 23 of the adjustable connecting rod 2.

The adjustable connecting rod 2 consists of a spiral sleeve 21, a U-shaped screw rod 22 and a pin shaft 23. The screw sleeve 21 is long rod shaped, and both ends are respectively provided with a left-handed screw hole and a right-handed screw hole. The U-shaped screw 22 has two pieces, which are left-hand threads and right-hand threads, respectively. The head of the U-shaped screw 22 is a U-shaped fork rod, a transverse unthreaded hole is formed in the U-shaped fork rod, and the bottom of the U-shaped fork rod is connected with the screw. The U-shaped screws 22 are screwed into two ends of the screw sleeve 21 respectively, and the pin shafts 23 are inserted into the unthreaded holes at the heads of the U-shaped screws.

The anchoring point 3 is a steel structure welding part, the horizontal part is a square steel plate, the vertical part is a triangular steel plate with an inverted top, and a unthreaded hole is formed in the triangular steel plate. There are 4 anchor points 3, and the bottom plate of each anchor point is welded on the embedded steel plate of the equipment foundation plane near the hanging lug 11 of the hopper 1.

Platform scale 4 installs in the pit of equipment foundation, and the upper surface flushes with equipment foundation plane, leaves a little distance with the pit lateral wall all around, and weighing sensor has been arranged at the four corners to the lower part.

The utility model also provides a using method of the zinc slag hopper weighing device, which comprises the following steps:

when weighing, the hopper 1 is horizontally placed in the middle of the platform scale 4, and no mechanical connection is formed between the platform scale 4 and the hopper. The pin shafts 23 at one ends of the four adjustable connecting rods 2 are respectively inserted into the unthreaded holes of the four lugs 11 of the hopper 1, the pin shafts 23 at the other ends are respectively inserted into the unthreaded holes of the vertical parts of the four anchoring points 3, and the screw sleeves 21 are adjusted to ensure that all 4 adjustable connecting rods 21 do not strain the lugs 11 of the hopper 1. The hopper 1 is not subjected to the tension of the adjustable connecting rod 2, and the weighing data of the platform balance 4 is only the weight of the hopper 1 plus the weight of the zinc dross.

When the zinc dross needs to be taken out, an operator uses a crane to demold and lift the cooled zinc dross out of the hopper, and the hopper 1 is limited by the adjustable connecting rod 2 in the vertical upward direction and cannot be lifted upwards along with the zinc dross, so that the smooth completion of the demolding of the zinc dross is ensured. Meanwhile, the weighing sensor of the platform balance 4 can only bear downward force, and the hopper 1 and the platform balance 4 are not mechanically connected, so that the platform balance 4 cannot bear upward force when the zinc dross is taken out, and the weighing sensor is effectively protected.
