Description

Technical Field

[0001] The utility model relates to the technical field of copper ore detection equipment, in particular to a furnace purge device. Background Art

[0002] In copper metal detection and analysis, the anode copper sample needs to be pulse heated, which requires the use of the ONH series analyzer. The ONH series analyzer is equipped with a pulse heating furnace, which is formed by the bite of the upper and lower electrodes. The pulse current flows through the high-resistance material to generate Joule heat for heating. After the pulse heating furnace is used, oxides or other waste slag will be produced on the surface of the electrode, making the furnace environment harsh. This requires the furnace electrode to be purged. The prior art handheld furnace purge tool enters the furnace to purge to ensure the furnace is clean and the electrode is conductive.

[0003] The length, accessibility and cleanliness of existing furnace purge tools cannot meet the purge requirements, and the operator needs to hold the tool and reach into the furnace for purge. If the equipment fails or other factors cause the upper and lower electrodes to bite, it will cause harm to the operator, posing a major safety hazard. Utility Model Content

[0022] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0023] Example:

[0024] like Figure 1-Figure 3 As shown, the utility model provides a furnace purge device, including a handle 1 and a purge head 2. The purge head 2 is connected to one end of the handle 1 and is combined with the handle 1 into an L shape. When the handle 1 is held, the purge head 2 can easily clean the top, bottom and both sides of the furnace. Channels 3 are provided inside the handle 1 and the purge head 2, and the channels 3 of the two are interconnected, so that the airflow can enter through the channel 3 of the handle 1 and flow out from one end of the purge head 2. The channel 3 inside the handle 1 extends from the end of the handle 1 to the front end, and is connected to the channel 3 of the purge head 2 at the front end. The channel 3 of the purge head 2 extends to the front end of the purge head 2. A connector 11 is provided at the rear end of the handle 1, which is convenient for connection with an air pump. Bristles 4 are provided on the outside of the purge head 2.

[0025] When the furnace blowing device of the utility model is used, air is ventilated inside the handle 1 so that airflow is blown out from the end of the blowing head 2. At the same time, the blowing head 2 can be extended into the furnace by holding the handle 1 and the inside of the furnace can be brushed by the bristles 4 of the blowing head 2. The debris brushed off by the bristles 4 is then blown away by the airflow sprayed by the blowing head 2, thereby cleaning the inside of the furnace well.

[0026] The inconvenience of inserting a hand tool into the furnace chamber is avoided by sending the cleaning head into the furnace chamber through the handle 1, and the potential safety hazard of inserting a hand into the furnace chamber is avoided. At the same time, the spraying can be better performed by brushing and spraying.

[0027] In this embodiment, the purge head 2 is rotatably arranged at one end of the handle 1. Specifically, a circular groove is arranged at one end of the handle 1, and one end of the purge head 2 is inserted into the circular groove and can rotate relative to the circular groove. The channel 3 of the purge head 2 is arranged along the rotation axis of the purge head 2. A plurality of impellers 5 are arranged on the inner wall of the channel 3 of the purge head 2 so that when the airflow passes through the impeller 5, the impeller 5 drives the purge head 2 to rotate. Then the purge head 2 rotates and scrubs the inner wall of the furnace. At the same time, the airflow can drive the purge head 2 to rotate without the need for other equipment to drive it. In order to better drive the purge head 2 to rotate, the channel 3 inside the purge head 2 is provided with multiple groups of impellers 5, so that multiple groups of impellers 5 jointly drive the purge head 2 to rotate. In addition, the air pressure of the gas source is generally relatively large, which can easily cause impurities inside the furnace to sputter during spraying. The airflow can be decelerated by a plurality of impellers 5, so that the ejected airflow is softer and the spraying effect is better.

[0028] In this embodiment, a rotating bearing 6 is provided between the blowing head 2 and the handle 1. The bearing makes the rotation of the blowing head 2 smoother and the cleaning effect better.

[0029] In this embodiment, the bristles 4 include hard bristles 7 and soft bristles 4. The hard bristles 7 can be copper wire bristles 4 or steel wire bristles 4, which are relatively hard and can be used to scrub the adhered impurities. The soft bristle brush is a brush made of animal hair or a brush made of fluff. It is mainly used to clean the impurities that are under the brush and in a free state. The outer wall of the purge head 2 is divided into several areas along its circumference, and the hard bristles 7 and the soft bristles 4 are arranged alternately according to the area. For example, the outer wall of the purge head 2 is evenly divided into two or six areas. The combination of the two brushes can better deal with various impurities in the furnace. In addition, the adhesions in the furnace generally do not require a large force to scrub. In actual operation, if you encounter harder adhesions, you can first let the purge head 2 rotate and accelerate to a very high speed, and use the inertia of the purge head 2 to generate a large instantaneous force to clean it. The flow rate of the airflow can also be adjusted to increase the scrubbing force of the purge head 2.

[0030] In this embodiment, the handle 1 is also provided with a channel 3 switch and a flow regulating valve 10. The channel 3 switch is used to control the on-off of the channel 3 in the handle 1; the flow regulating valve 10 is used to control the flow rate of the airflow, thereby being more suitable for actual needs.

[0031] In this embodiment, an air pump and an air suction pump are also included. Both the air pump and the air suction pump are connected to the air inlet of the handle 1. Both the air pump and the air suction pump are provided with an air valve. The air valve can be used to control the air pump or the air suction pump to be connected to the handle 1. When the air pump is connected, the purge head 2 rotates to scrub and spray air, thereby brushing away the debris. When the air suction pump is connected, the purge head 2 reverses, scrubbing and sucking away dust and debris at the same time.

[0032] In this embodiment, the outer diameter of the front end of the purge head 2 is smaller than the outer diameter of the rear end, so that the purge head 2 is conical. The front end of the purge head 2 is thinner and can be extended into the gaps in the furnace for brushing.

[0033] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention may be subject to various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
