Description

Technical Field

[0001] The present application relates to the technical field of metal detection, and in particular to a metal detection device for an emulsion explosive production line. Background Art

[0002] Emulsion explosive is a new type of industrial explosive. It is commonly used in blasting and excavation projects. The production of emulsion explosive is to transport the emulsion explosive pre-product to the mixing hopper through a conveyor belt, mix wood powder and other materials in the mixing hopper, stir and mix, and then transport it to the charging machine for charging. After the charging is completed, the emulsion explosive product is formed. In actual production, due to the recycling and reuse of waste drugs, unqualified emulsion explosives collected from various process equipment or on the ground will be mixed with more or less impurities. These impurities may contain metal impurities. When metal impurities are mixed and stirred in the hopper, they are easy to rub against the hopper, which may damage the equipment at the least and cause explosion accidents at the worst. Therefore, the absence of metal impurities in emulsion explosives is one of the prerequisites for ensuring safe production.

[0003] In the prior art, firstly, impurities on the production line are removed by manual inspection and removal. However, metal impurities are not easily distinguished from the color after being mixed with the pre-product of emulsion explosive, resulting in incomplete removal of metal impurities. Another method is to remove impurities through a structure that can remove the medicine pile. The structure can detect whether there is metal in the medicine pile. If so, the whole medicine pile is removed. However, since the medicine pile exists in piles, there is a situation where the detection cannot be in place, and the detection accuracy is low. In addition, this structure will remove excess medicine piles. After subsequent manual removal, the medicine pile needs to be put back on the production line. The process is cumbersome and affects production efficiency.

[0004] Therefore, there is an urgent need for a metal detection device for an emulsion explosive production line to solve the above problems. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] The present application provides a metal detection device for an emulsion explosive production line, which is used to improve detection accuracy and production efficiency. The specific implementation process of the present application is described as follows.

[0033] See also Figures 1 to 5 The present application provides a metal detection device for an emulsion explosive production line, comprising:

[0034] Conveyor belt 1, metal detector 2, vibration table 3; the vibration table 3 includes a vibration table 31 and a fixed table 32, the lower surface of the fixed table 32 is provided with a support foot for contacting the ground, the upper surface of the fixed table 32 is provided with a recessed area, the recessed area is provided with a vibration component 33, the vibration table 31 is located in the recessed area and connected to the vibration component 33; the conveyor belt 1 is fixed on the vibration table 31, the metal detector 2 is fixed on the fixed table 32, the detection end of the metal detector 2 is located above the conveyor belt 1, and the metal detector 2 is used to detect metal impurities on the conveyor belt 1 and issue an alarm.

[0035] like Figure 1 As shown, the conveying direction of the conveyor belt 1 is from left to right, and the emulsion explosive is placed on the left side of the conveyor belt 1. When the conveyor belt 1 is running, the emulsion explosive is moved to the right, and the moving process passes under the metal detector 2. The detection direction of the metal detector 2 is downward. At this time, the metal detector 2 can detect whether the emulsion explosive located below contains metal impurities.

[0036] The vibration table 3 is used to provide vibration, wherein the fixed table 32 is in a fixed state, the recessed area on the fixed table 32 is larger than the vibration table 31, the vibration table 31 is embedded in the recessed area, the vibration component 33 is respectively connected to the vibration table 31 and the fixed table 32 up and down, and the vibration table 31 is in a suspended movable state through the vibration component 33. A vibration machine is arranged in the vibration table 31, and when the vibration machine vibrates, it drives the vibration table 31 to vibrate; since the conveyor belt 1 is connected to the vibration table 31, the conveyor belt 1 will also vibrate, and the emulsion explosive will be flattened during the vibration process, and since the mass and size of the metal impurities are different from those of the emulsion explosive, the metal impurities will be separated from the emulsion explosive during the vibration process, so that when passing through the metal detector 2, they can be detected by the metal detector 2.

[0037] Optional, please continue to Figure 4 In one practicable manner, inclined baffles 6 are provided on both sides of the conveyor belt 1, and the upper ends of the baffles 6 are inclined outwards, and the baffles 6 are used to prevent the emulsion explosive from being scattered to both sides during the vibration process. It is understood that the highest point of the baffle 6 should be lower than the lower surface of the metal detector 2.

[0038] In this embodiment, the conveyor belt 1 is arranged on the vibration table 31 of the vibration table 3, and the vibration of the conveyor belt 1 is driven by the vibration of the vibration table 31, so that the emulsion explosive on the conveyor belt 1 can be flattened and separated from the metal impurities during the vibration process, which is convenient for the metal detection of the metal detector 2 and the alarm is issued in time after detection. Through this application, the accuracy of metal detection on the emulsion explosive transportation line can be improved. Compared with the prior art of removing the entire pile of explosives to remove metal impurities, this application can simplify the steps and improve efficiency.

[0039] Optionally, the metal detection device of the present application also includes a heating component 5, which is located in the middle of the conveyor belt 1 and is connected to the fixed platform 32. In practice, the heating component 5 is used to increase its own temperature, thereby increasing the temperature of the upper conveyor belt 1. When the temperature of the conveyor belt 1 is increased, the temperature of the emulsion explosive on the conveyor belt 1 is increased, thereby drying the emulsion explosive, further facilitating the separation of metal impurities from the emulsion explosive by vibration. The heating component 5 is connected to the fixed platform 32, so the heating component 5 does not vibrate. It should be noted that the heating component 5 is only used for drying, and its heating temperature is lower than the ignition point of the emulsion explosive.

[0040] Optional, please continue to Figure 3 The heating assembly 5 includes a support 61, a heating wire 52 and a fence 53. The first end of the support 51 is connected to the fixed platform 32, and the second end extends upward to the middle of the conveyor belt 1. The heating wire 52 and the fence 52 are arranged on the second end of the support 51, and the fence 53 is located on both sides of the heating wire 52. In this embodiment, the heating wire 52 is electrically heated, and a power supply is arranged in the support 51, which is used to supply electricity to the heating wire 52 to generate heat. In addition, the heating wire 52 is wrapped with a layer of plastic, which can prevent the heating wire 52 from being exposed, and the plastic will not melt at the heating temperature of the heating wire 52. The fence 53 is in an inclined state, which can reduce impurities entering the heating wire 52 area, and can also limit the temperature diffusion to ensure that the temperature of the heating wire 52 reaches the conveyor belt 1 upward.

[0041] Optionally, the heating temperature range of the heating wire is 30-45 degrees.

[0042] Optionally, the heating wire is made of copper, iron-chromium-aluminum alloy or nickel.

[0043] Optionally, the metal detection device provided in the present application also includes a metal adsorber 4, which is located above the conveyor belt 1, and the metal detector 4 is connected to the fixed platform 32, and the metal adsorber 4 is used to adsorb metal impurities on the conveyor belt 1. In practice, in the transport direction of the conveyor belt 1, the metal adsorber 4 is located in front of the metal detector 2. During the vibration process, the emulsion explosive is separated from the metal impurities, and the metal impurities are adsorbed by the metal adsorber 4 when passing under the metal adsorber 4, thereby achieving the effect of removing the metal impurities. In this embodiment, the metal adsorber 4 adsorbs metal impurities by magnetic attraction. By setting up the metal adsorber 4, the effect of automatically removing metal impurities can be achieved, thereby reducing the cost of manual removal. It can be understood that the metal impurities adsorbed on the metal adsorber 4 can be cleaned regularly to ensure the adsorption strength of the metal adsorber 4. The timing here can be 3 hours, 5 hours, etc., which is specifically set according to the actual scene and is not limited here.

[0044] Optionally, the metal adsorber 4 is connected to the fixing platform 32 in a detachable manner. In this embodiment, the detachable manner enables the metal adsorber 4 to be disassembled for easy maintenance and replacement.

[0045] Optionally, the material of the conveyor belt 1 is rubber. In order to prevent the conveyor belt 1 from affecting the detection result of the metal detector 2, in this embodiment, the material of the conveyor belt 1 is set to rubber.

[0046] Optionally, in one achievable manner, the metal detector 2 includes a detection plate 21 and a telescopic column 22 , one end of the telescopic column 22 is connected to the fixed platform 32 , and the other end is connected to the detection plate 21 , and the height of the detection plate 21 can be adjusted through the telescopic column 22 .

[0047] It should be noted that the above description of the disclosed embodiments enables professionals and technicians in the field to implement or use the present application. Various modifications to these embodiments will be apparent to professionals and technicians in the field, and the general principles defined herein can be implemented in other embodiments without departing from the scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but should conform to the widest scope consistent with the principles and novel features disclosed herein.
