Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of solution cleaning, and particularly relates to a smelting furnace cleaning device. BACKGROUND

[0002] In the die-casting production process, when facing the situation of changing the die-casting material or the smelting furnace needing maintenance, the common way in the prior art is to manually scoop out the solution in the smelting furnace with a spoon. Obviously, this way has many disadvantages.

[0003] From the perspective of time and energy consumption, the operation efficiency of manually scooping out the solution is extremely low. On the one hand, the die-casting smelting furnace usually has a certain capacity and contains a large amount of die-casting material in a high-temperature liquid state. It takes hours to scoop out the solution by manpower. For example, for a smelting furnace commonly used in a medium-sized factory, which has a volume of hundreds of liters, even if multiple workers are arranged to work simultaneously, the whole scooping process may last for several hours, during which the production line has to be stopped, greatly affecting the production progress and capacity.

[0004] On the other hand, this is a heavy physical labor that consumes a lot of physical strength. The workers need to hold heavy metal spoons for a long time and repeatedly scoop out the solution in a high-temperature radiation environment, which is extremely easy to cause fatigue. Each scoop of solution weighs several kilograms or even dozens of kilograms. After continuous operation for a period of time, the worker's arm muscles often ache and become weak, and the action also slows down, further slowing down the scooping process.

[0005] Further analysis from the aspect of safety hazards shows that the high-temperature liquid die-casting material itself is extremely dangerous. First of all, when the workers scoop out the solution at close range, they are extremely easy to be scalded by the high-temperature solution splashed out or by the hot furnace wall. The scalded wounds are often serious and have a long healing period, causing great pain to the workers.

[0006] Secondly, due to the instability of manual operation, there is a risk of solution splashing during the scooping process. Once splashed out, it not only scalds the surrounding workers, but also may ignite the surrounding flammable materials, causing a fire accident. If splashed onto electrical equipment, it may also cause electrical faults such as short circuit and electric shock, threatening the electrical safety of the whole workshop and causing a series of chain reactions, endangering the safety of personnel and property.

DETAILED DESCRIPTION

Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the utility model.

[0032] It should be noted that the terms "first", "second" and the like in the specification and claims of the utility model and the above-mentioned drawings are used to distinguish similar objects and do not necessarily describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the utility model described herein can be implemented in an order other than those illustrated or described herein.

[0034] As Figure 1 As shown is a perspective view of the furnace cleaning device in a certain direction provided by the utility model embodiment, the furnace cleaning device comprises a liquid pumping unit 100, a liquid outlet unit 200 and a supporting unit 300, wherein the liquid pumping unit 100 is used to pump out the solution in the furnace, when pumping out the solution in the furnace, the liquid pumping unit 100 will extend into the solution of the furnace, as Figure 2As shown is the explosion map of the liquid extraction unit 100 provided by the embodiment of the utility model, the liquid extraction unit 100 can include sleeve 110 and screw rod 120, screw rod 120 is rotatably sleeved in sleeve 110, screw rod 120 can have screw rod shaft 121 and conveying thread 122, and conveying thread 122 is arranged on screw rod shaft 121, so that screw rod 120 can utilize the conveying thread 122 possessed by itself to convey solution along the channel formed between conveying thread 122 and sleeve 110 to the tail end of conveying thread 122 when rotating, in order to guarantee the existence of solution conveying channel, it can be understood that a certain gap needs to be left between sleeve 110 and screw rod 120, and in order to make the solution be conveyed along with conveying thread 122, conveying thread 122 needs to be made to spiral upward along the conveying direction when setting, for example, the conveying direction can be the axial direction of screw rod shaft 121, then conveying thread 122 can be made to spiral upward along the conveying direction.

[0035] Further, in order to guarantee the transmission of solution by screw rod 120, the length of screw rod 120 can be matched with the distance to be transmitted, when making screw rod 120 rotate, screw rod shaft 121 can be made to rotate, and then conveying thread 122 is driven to rotate synchronously, to convey solution.

[0036] The liquid outlet unit 200 is used to send the solution extracted by the liquid extraction unit 100 to the place where it is needed. Figure 3 As shown is the perspective view of the furnace cleaning device provided by the embodiment of the utility model from another angle, the liquid outlet unit 200 can be provided with a liquid inlet and a liquid outlet, and the liquid inlet of the liquid outlet unit 200 is connected with the liquid outlet of the liquid extraction unit 100 in a through manner, so that the solution extracted by the liquid extraction unit 100 can enter the liquid outlet unit 200, and the liquid outlet of the liquid outlet unit 200 is used to convey the solution to the place where it is needed. The structure of the liquid outlet unit 200 can be any structure capable of outputting solution, optionally, in order to guarantee that the liquid outlet unit 200 does not hang liquid, the liquid outlet unit 200 can be set to be cylindrical. A liquid outlet channel is formed between the liquid inlet and the liquid outlet, when the temperature of the solution is relatively high, the air pressure in the liquid outlet channel is relatively large, which can cause explosion, therefore, the liquid outlet unit 200 can be provided with a slot 210 penetrating the liquid outlet channel on the side away from the vertical direction, for reducing the air pressure in the liquid outlet channel.

[0037] Further, the support unit 300 can be supported below the liquid extraction unit 100 and the liquid outlet unit 200, so as to support the liquid extraction unit 100 and the liquid outlet unit 200, so that the liquid extraction unit 100 and the liquid outlet unit 200 are more stable when working, and the support unit 300 can also be set to have a certain height, so that the liquid extraction unit 100 and the liquid outlet unit 200 can be located at different heights, to adapt to more application scenarios.

[0038] Thus, the furnace cleaning device can realize automatic cleaning of the furnace, thereby avoiding the problems of low efficiency and potential safety hazards caused by cleaning the solution in the furnace by using the manual method in the prior art.

[0039] Optionally, as shown in Figure 3 The liquid outlet unit 200 can be provided with a sealing portion 220, which can be in communication with the liquid inlet of the liquid outlet unit 200.

The sealing portion 220 can be any closed structure, for example, if the liquid outlet unit 200 is a hollow tubular structure, the sealing portion 220 can be a continuous structure without notches adjacent to the liquid inlet of the liquid outlet unit 200. Further, a slot 210 can be provided between the sealing portion 220 and the liquid outlet of the liquid outlet unit 200 to reduce the pressure inside the liquid outlet unit 200.

It can be understood that the cylindrical shape has the advantage of not hanging liquid compared to the prismatic shape. The length of the sleeve 110 and the screw shaft 121 along the axial direction of the screw shaft 121 matches. It can be understood that the length of the sleeve 110 and the screw shaft 121 matches, which can make the solution channel formed between the sleeve 110 and the screw shaft 121 match the length of the sleeve 110 and the screw shaft 121, thereby avoiding the actual solution channel formed when the length of the sleeve 110 and the screw shaft 121 does not match being smaller than the maximum length of the sleeve 110 and the screw shaft 121, thereby causing waste of the sleeve 110 or the screw shaft 121.

Specifically, the rotating power assembly 130 can be any component that can provide rotary power, such as a brushless motor.

[0043] Optionally, the inner wall of the sleeve 110 and the conveying thread 122 can be polished, so that the inner wall of the sleeve 110 and the conveying thread 122 are smooth enough and do not hang liquid. In addition, the inner wall of the liquid outlet unit 200 can also be polished.
