Description

Technical Field

[0001] The present invention relates to weighing mechanical equipment, and more particularly to a zinc slag hopper weighing device and a use method thereof. Background Art

[0002] The zinc slag on the surface of the zinc bath in a galvanizing line significantly negatively impacts the surface quality of the finished product and must be removed regularly. The current technological trend is toward automated slag removal, where the removed slag is poured into a hopper that is weighed to determine if it is full. If the hopper is full, the equipment suspends automatic slag removal, and the cooled slag is manually removed from the hopper before automatic slag removal resumes. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a zinc slag hopper weighing device capable of realizing automatic weighing of the zinc slag hopper and a method of using the device.

[0004] The technical solution adopted by the present invention to solve the technical problem is: constructing a zinc slag hopper weighing device, including a hopper, an adjustable connecting rod, an anchor point and a platform scale; the hopper opening is upward, the bottom is flat, and the sides are inclined inward, and each of the four corners of the hopper is provided with a hanging ear;

[0005] The adjustable connecting rods are provided with four, each of which includes a spiral sleeve, two U-shaped screws and two pins. The spiral sleeve is in the shape of a long rod, with a left-hand threaded hole and a right-hand threaded hole respectively opened at both ends. The two U-shaped screws are left-handed and right-handed respectively. The U-shaped screw includes a screw portion and a U-shaped fork rod. The fork rod is provided with a transverse light hole. The bottom of the fork rod is connected to the screw portion. The U-shaped screws are respectively screwed into the two ends of the spiral sleeve, and the pins are inserted into the light holes of the fork rods. The adjustable connecting rod is connected to the hanging ear and the anchor point through the pin.

[0006] The platform scale is installed in the pit of the equipment foundation, and the upper surface is flush with the equipment foundation plane; four anchoring points are provided, which are distributed on the equipment foundation plane around the platform scale.

[0007] In the above solution, the hopper is formed by welding steel plates or integrally casting.

[0008] In the above solution, the hanging lug is made of steel plate and vertically welded to the outside of the hopper side.

[0009] In the above solution, a circular hole is provided at the end of the hanging ear, and the diameter of the circular hole at the end of the hanging ear is larger than the diameter of the pin shaft of the adjustable connecting rod.

[0010] In the above solution, the hopper is further provided with a lifting lug, which is a barb made of steel plate and is vertically welded to the outside of the side of the hopper.

[0011] In the above solution, the anchor point is a steel structure welded part, the horizontal part is a square steel plate, and the vertical part is a triangular steel plate with a rounded top and a light hole opened on it.

[0012] In the above solution, a weighing sensor is arranged at the lower part of the platform scale.

[0013] The present invention also provides a method for using the zinc slag hopper weighing device. During weighing, the hopper is placed flat in the center of a platform scale without any mechanical connection between the hopper and the platform scale. The pins at one end of four adjustable connecting rods are respectively inserted into the light holes of the four hanging ears of the hopper, and the pins at the other ends are respectively inserted into the light holes of the vertical parts of the four anchor points. The spiral sleeves are adjusted so that all four adjustable connecting rods do not tighten the hanging ears of the hopper. At this time, the hopper is not subjected to the tension of the adjustable connecting rods, and the weighing data of the platform scale is only the weight of the hopper plus the weight of the zinc slag.

[0014] When the weighing is completed and the zinc slag needs to be removed, the operator uses a crane to demold the cooled zinc slag from the hopper. Since the hopper is in the vertical upward direction, it is restricted by the adjustable connecting rod and will not be lifted upward with the zinc slag, and the zinc slag is demolded.

[0015] The zinc slag hopper weighing device of the present invention has the following beneficial effects:

[0016] The present invention can realize automatic weighing of the zinc slag hopper, and the hopper will not move during the process of removing the zinc slag and demoulding, thereby providing a guarantee for the subsequent automatic slag scooping operation, and the platform scale will not be subjected to an upward force, thereby effectively protecting the weighing sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments, in which:

[0018] Figure 1 It is a structural schematic diagram of the zinc slag hopper weighing device of the present invention;

[0019] Figure 2 It is a structural diagram of the hopper. DETAILED DESCRIPTION

[0020] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.

[0021] like Figure 1-2 As shown, the zinc slag hopper weighing device of the present invention includes a hopper 1, an adjustable connecting rod 2, an anchor point 3, and a platform scale 4.

[0022] The hopper 1 is welded or integrally cast from steel plates. It opens upward, has a flat bottom, and inward-sloping sides. Each of the four corners of the hopper 1 is equipped with a hook 11 and a lifting lug 12. The hook 11 is machined from steel plates and welded vertically to the exterior of the hopper 1. The end of the hook 11 has a circular hole 112. The lifting lug 12 is a barbed hook machined from steel plates and welded vertically to the exterior of the hopper 1. The diameter of the circular hole 112 at the end of the hook 11 is larger than the diameter of the pin 23 of the adjustable connecting rod 2.

[0023] The adjustable connecting rod 2 consists of a spiral sleeve 21, a U-shaped screw 22, and a pin 23. The spiral sleeve 21 is a long rod with a left-handed threaded hole and a right-handed threaded hole at each end. The U-shaped screw 22 consists of two parts, one with a left-handed thread and the other with a right-handed thread. The head of the U-shaped screw 22 is a U-shaped fork with a transverse aperture. The bottom of the U-shaped fork is connected to the screw. The U-shaped screw 22 is screwed into the ends of the spiral sleeve 21, and the pin 23 is inserted into the aperture at the head of the U-shaped screw.

[0024] Anchor points 3 are welded steel components, with the horizontal portion being a square steel plate and the vertical portion being a triangular steel plate with a rounded top and a light hole. There are four anchor points 3, and their bases are welded to a pre-embedded steel plate on the equipment foundation plane near the hopper 1's lugs 11.

[0025] The platform scale 4 is installed in the pit of the equipment foundation, with its upper surface flush with the equipment foundation plane, and a small distance left between the four sides and the side walls of the pit. Weighing sensors are arranged at the four corners of the lower part.

[0026] The present invention also provides a method for using the zinc slag hopper weighing device, which is specifically as follows:

[0027] During weighing, hopper 1 rests flat in the center of platform scale 4, with no mechanical connection to the platform scale 4. The pins 23 at one end of the four adjustable links 2 are inserted into the clear holes in the four lugs 11 of hopper 1, while the pins 23 at the other end are inserted into the clear holes in the vertical portions of the four anchor points 3. The spiral sleeves 21 are adjusted so that all four adjustable links 21 do not pull on the lugs 11 of hopper 1. Therefore, hopper 1 is not subject to any tension from the adjustable links 2, and the weight recorded on platform scale 4 is simply the weight of hopper 1 plus the weight of the zinc slag.

[0028] When the slag needs to be removed, the operator uses a crane to lift the cooled slag out of the hopper. Because hopper 1 is vertically upward, restrained by adjustable connecting rod 2, it is prevented from being lifted upward along with the slag, ensuring smooth demolding. Furthermore, because the load cell of platform scale 4 can only withstand downward forces and there is no mechanical connection between hopper 1 and platform scale 4, the platform scale 4 is not subjected to upward forces when removing the slag, effectively protecting the load cell.

[0029] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which are protected by the present invention.
