Description

Technical Field

[0001] The utility model relates to the technical field of slag knocking equipment, and more specifically to a metal slag knocking mechanism. Background Art

[0002] In the field of metallurgy, metals are molten in a furnace at high temperatures, and it is usually necessary to detect the liquid level of the furnace. For example, in a copper smelting flash furnace, after the raw materials react in the flash furnace, the reaction products will be clarified and separated in the sedimentation tank due to different densities. The basis for melt discharge control in the flash furnace production process is the height of the two melt levels in the flash furnace. Therefore, monitoring the melt level in the flash furnace sedimentation tank plays a vital role in the stability and safety of the flash copper smelting production process.

[0003] The liquid level detection device in the prior art includes a frame, on which a lifting device is installed. The lifting device drives the probe rod to move up and down. The probe rod enters the furnace, and the molten metal is also attached to the probe rod. Then, the industrial camera takes a picture of the probe rod to complete the liquid level detection. The probe rod is then clamped by a clamping mechanism, and finally the metal slag on the probe rod is knocked off by a knocking mechanism. Figure 1 This is a schematic diagram of the knocking mechanism. The motor drives the cam, the cam drives the connecting shaft, the connecting shaft drives the pendulum and the vertical part on the pendulum to swing and knock the probe. This structure can only knock on one side of the probe when knocking, which has certain limitations, resulting in the metal slag on the other side of the probe not being knocked off. In addition, since the structure is that the swing of the pendulum drives the hammer to knock, its swing needs to have a certain stroke, resulting in a low knocking frequency and the metal slag cannot be completely cleaned. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide a metal slag knocking mechanism which can knock back and forth at high frequency on both sides of a probe rod.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions. A metal slag beating mechanism, including a probe rod and a frame, a slide plate located on one side of the probe rod is installed on the frame, a slider is installed on the slide plate for horizontal sliding, a beating hammer is installed on both ends of the slider, and the probe rod is located between the two beating hammers; a connecting shaft is installed on the slide plate, a push block is installed on the end of the connecting shaft away from the slide plate, a telescopic driver with an output end axially parallel to the sliding direction of the slide plate is also installed on the frame, an elastically deformable driving piece is installed on the output end of the telescopic driver, and an elastic member for storing force for the beating hammer is installed at intervals on the side of the two beating hammers away from the probe rod; the driving piece pushes the push block back and forth to make the beating hammer store force and release force, thereby allowing the two beating hammers to knock the probe rod back and forth.

[0006] Preferably, both ends of the slide plate are vertically bent toward the direction of the probe rod to form a stop plate, and the elastic member is installed on the stop plate.

[0007] Preferably, the elastic member is a spring.

[0008] Preferably, a sliding groove penetrating the sliding plate is provided on the sliding plate, and the connecting shaft passes through the sliding groove and extends in a direction away from the probe rod.

[0009] Preferably, the push block adopts a cam with a protrusion facing upward, and the driving piece is located on one side of the cam. The driving piece pushes the cam to move so that when the driving piece reaches the limit, it is deformed and slips off the cam to release the striking hammer.

[0010] Preferably, the telescopic driver is located on a side of the push block away from the probe rod, and a connecting rod extending toward the push rod is installed at the output end of the telescopic driver, and the driving piece is installed on the connecting rod.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] (1) The telescopic driver drives the push block to drive the slider and the striking hammer to move. The striking hammer presses on the elastic member to store force. After the force is released, due to the action of the elastic member, the striking hammer can strike the probe rod back and forth at a high frequency, thereby improving the striking efficiency.

[0013] (2) By setting up double hammers, the slag can be knocked back and forth on both sides of the probe rod, making the knocking more thorough. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] refer to Figure 1-2 A metal slag beating mechanism includes a probe rod 11 and a frame 1, on which a slide plate 2 is installed at one side of the probe rod 11, on which a slider 3 is installed horizontally and slidably, and both ends of the slider 3 are installed with a beating hammer 4, and the probe rod 11 is located between the two beating hammers 4. Here, the sliding installation of the slider 3 and the slider 2 can be provided by opening a slide groove 22 on the slider 2, and the slider 2 slides into the slide groove 22 for sliding installation, or a sliding installation of a limited pulley rail can be adopted. By sliding the slider 3 back and forth on the slider 2, the beating hammer 4 strikes the probe rod 11 back and forth as the slider 3 moves. The sliding of the slide plate 2 needs to be driven, so a connecting shaft 6 is installed on the slide plate 2, and a push block 7 is installed on the end of the connecting shaft 6 away from the slide plate 2. A telescopic driver 8 with an output end axially parallel to the sliding direction of the slide plate 2 is also installed on the frame 1. The output end of the telescopic driver 8 is installed with an elastically deformable driving piece 81, and the two sides of the knocking hammers 4 away from the probe rod 11 are spaced apart and installed with elastic parts 5 for storing force for the knocking hammers 4; the driving piece 81 pushes the push block 7 back and forth to make the knocking hammers 4 store force and release force, thereby allowing the two knocking hammers 4 to knock the probe rod 11 back and forth. It can be understood that the elastic part 5 has an elastic force storage function, and elastic parts such as springs can be used. The driving piece 81 on the telescopic driver 8 pushes the push block 7 to one side, pressing it on the spring, so that the knocking hammer 4 stores elastic potential energy. After the driving piece 81 releases the push block, the elastic potential energy of the spring is converted into kinetic energy of the knocking hammer 4, which then moves quickly to knock the probe rod 11. Since there is also a spring at the other end, the spring is compressed and then rebounds after the impact, causing the knocking hammer 4 to move in the direction, and then the two knocking hammers 4 will knock the probe rod 11 back and forth on the slide plate 2.

[0021] In some embodiments, the two ends of the slide plate 2 are bent vertically toward the probe rod 11 to form a butt plate 21, and the elastic member 5 is installed on the butt plate 21. Here, the spring only needs to be fixed, so other fixing members can also be installed on both sides of the hammer 4, and then the spring is installed on the fixing members.

[0022] In some embodiments, a slide groove 22 is provided on the slide plate 2, and the connecting shaft 6 extends through the slide groove 22 in a direction away from the probe rod 11. In this way, the overall structure will be more compact. Of course, the connecting shaft 6 can also be bent so that one end of the connecting shaft 6 is connected to the slider 3, and the other end is bent upward, and then bent horizontally in a direction away from the probe rod 11 to extend out of the slide plate 2.

[0023] In some embodiments, the push block 7 adopts a cam with a protrusion facing upward, and the driving piece 81 is located on one side of the cam. The driving piece 81 pushes the cam to move so that the driving piece 81 deforms and slips off the cam when it reaches the limit, thereby releasing the knocking hammer 4. Here, the driving piece 81 can be made of an elastic plastic sheet, an elastic metal sheet, etc. For example, the telescopic driver 8 moves the push block 7 to one side through the driving piece 81. Due to the action of the spring, there is resistance to the pushing of the driving piece 81, and the longer the pushing distance, the greater the resistance. When the active force is greater than the bearing capacity of the driving piece 81, the driving piece 81 will be deformed and then slip off the cam, and the knocking hammer 4 will be pushed by the spring elasticity to knock the probe 11. After the driving piece 81 elastically recovers to its original shape, the telescopic drive pulls back and pulls the cam again, so that the knocking hammer 4 accumulates force again. It works repeatedly in this way. Furthermore, in order to prevent the telescopic driver 8 from hindering the movement of the cam, the telescopic driver 8 is located on the side of the push block 7 away from the probe rod 11, and a connecting rod 82 extending in the direction of the push rod is installed at the output end of the telescopic driver 8, and the driving piece 81 is installed on the connecting rod 82. The telescopic driver 8 can be a cylinder, an electric push rod, etc.

[0024] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
