Description

Technical Field

[0001] This utility model relates to the field of muffle furnace cleaning technology, and in particular to a muffle furnace that facilitates waste removal. Background Technology

[0002] A muffle furnace is a high-temperature heating device used for heat treatment of materials, such as ashing and sintering. Its furnace chamber is made of refractory material and contains heating elements. Cleaning the muffle furnace is essential to remove residues and ensure heating efficiency and sample purity. During use, waste or impurities from previous experiments may remain inside the furnace chamber. These residues can affect the accuracy of new experiments and the heating efficiency of the equipment. Therefore, regular cleaning of the waste from the inner wall of the muffle furnace is crucial. For ease of cleaning, a muffle furnace designed for convenient waste removal is necessary.

[0003] A search revealed the Chinese patent "A Muffle Furnace Easy to Clean" (publication number CN220304201U). This easy-to-clean muffle furnace, through the installation of a main body mechanism, enables the furnace body to automatically move a scraper up and down according to usage requirements during heat processing operations. This scrapes away impurities adhering to the inner wall of the muffle furnace body. Combined with the design of the flushing component, it achieves thorough cleaning of the interior of the muffle furnace body, ensuring the normal operation of the muffle furnace body for subsequent heat processing operations. This improves the automation and protection of the muffle furnace body.

[0004] Although the aforementioned application can slide the impurities attached to the inner wall of the muffle furnace body by moving the scraper up and down, the scraper can only scrape the inner side wall of the muffle furnace and cannot clean the inner top wall of the muffle furnace.

[0005] Therefore, a muffle furnace that facilitates waste removal is proposed to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a muffle furnace that facilitates waste cleaning in order to solve the above-mentioned problems, thereby improving the problem of not being able to clean the top wall inside the muffle furnace.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a muffle furnace that facilitates waste cleaning, comprising: a furnace body, a furnace chamber, and a temperature control system, wherein the furnace chamber is disposed inside the furnace body, and the temperature control system is disposed on the surface of the furnace body;

[0008] The cleaning mechanism includes a cleaning cylinder disposed outside the furnace body. The cleaning cylinder has three first scrapers on its outside and a second scraper at its top. The cleaning cylinder has two liquid storage tanks inside, and the surfaces of the liquid storage tanks are connected to rotating nozzles that penetrate the cleaning cylinder.

[0009] Preferably, the cleaning cylinder is disposed on one side of the furnace body surface, and a folding rod is provided between the cleaning cylinder and the furnace body. One end of the folding rod is hinged to the furnace body and the other end is fixedly connected to the cleaning cylinder. This allows for cleaning of the furnace chamber without occupying internal space within the furnace chamber.

[0010] Preferably, the cleaning cylinder is equipped with a reciprocating lead screw inside, and the surface of the reciprocating lead screw is provided with a threaded block. The bottom end of the liquid storage tank is fixedly connected to the inner bottom wall of the cleaning cylinder, and the top end passes through the threaded block and the top end of the cleaning cylinder, and is provided with a water inlet. Spraying cleaning liquid improves the cleaning effect.

[0011] Preferably, a drive motor is fixedly connected to the bottom end of the reciprocating screw, the drive motor is fixedly connected to the inner bottom wall of the cleaning cylinder, and the top end of the reciprocating screw is fixedly connected to the second scraper. This drives the first scraper to repeatedly scrape the side wall of the furnace.

[0012] Preferably, a telescopic rod is fixedly connected between the threaded block and the three first scrapers. The three first scrapers correspond to the three inner walls of the furnace, and each of the first scrapers has a through groove on its surface. This allows waste material to be transferred to the water inlet trough in a timely manner.

[0013] Preferably, a resistance wire is provided at the bottom of the furnace chamber, and a platform is provided above the resistance wire.

[0014] Preferably, a first water inlet trough is fixedly connected to both sides of the platform, and a second water inlet trough is fixedly connected to the side of the platform closer to the furnace interior. The two first water inlet troughs are slidably connected to the furnace interior. This ensures timely discharge of waste materials.

[0015] The beneficial effects of this utility model are:

[0016] 1. By setting a threaded block to move up and down with the reciprocating screw, the first scraper moves up and down synchronously to scrape the waste on the side wall of the furnace. At the same time, the rotation of the reciprocating screw will drive the second scraper to rotate and scrape the top wall of the furnace. The cleaning fluid sprayed by the rotating nozzle can clean the side wall of the furnace and also clean the top wall of the furnace.

[0017] 2. By setting up a folding rod in conjunction with the cleaning mechanism, the furnace can be cleaned without altering its internal structure, reducing instability caused by internal changes. By setting up a water inlet, the sprayed cleaning liquid can be directly led out of the furnace, reducing contact between the furnace interior and water and increasing the furnace's stability.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] In practical implementation: such as Figure 1-5 As shown, a muffle furnace that facilitates waste removal includes: a furnace body 100, a furnace chamber 110, and a temperature control system 200. The furnace chamber 110 is disposed inside the furnace body 100, and the temperature control system 200 is disposed on the surface of the furnace body 100.

[0026] The cleaning mechanism 400 includes a cleaning cylinder 410 disposed outside the furnace body 100. The cleaning cylinder 410 is provided with three first scrapers 420 on its exterior and a second scraper 430 on its top. The cleaning cylinder 410 is provided with two liquid storage tanks 440 inside, and a rotating nozzle 441 that penetrates through the cleaning cylinder 410 is connected to the surface of the liquid storage tanks 440.

[0027] like Figure 1 , Figure 4 and Figure 5As shown, a cleaning cylinder 410 is disposed on one side of the surface of the furnace body 100. A folding rod 500 is provided between the cleaning cylinder 410 and the furnace body 100. One end of the folding rod 500 is hinged to the furnace body 100 and the other end is fixedly connected to the cleaning cylinder 410. A reciprocating screw 411 is provided inside the cleaning cylinder 410. A threaded block 412 is provided on the surface of the reciprocating screw 411. The bottom end of the liquid storage tank 440 is fixedly connected to the inner bottom wall of the cleaning cylinder 410, and the top end passes through the threaded block 412 and the cleaning cylinder 440. A water inlet is provided at the top of the cylinder 410. A drive motor 413 is fixedly connected to the bottom of the reciprocating screw 411. The drive motor 413 is fixedly connected to the inner bottom wall of the cleaning cylinder 410. The top of the reciprocating screw 411 is fixedly connected to the second scraper 430. A telescopic rod 422 is fixedly connected between the threaded block 412 and the three first scrapers 420. The three first scrapers 420 correspond to the three inner walls of the furnace 110 respectively. A through groove 421 is opened on the surface of each first scraper 420.

[0028] In this embodiment, the folding rod 500 consists of two hinged crossbars and an "L"-shaped rod. The crossbar hinged to the furnace body 100 is a telescopic crossbar with sliding friction. The furnace body 100 has a furnace door on its surface, which is located above the temperature control system 200. The telescopic rod 422 has a spring inside, which can provide pressure to the furnace chamber 110 when the first scraper 420 cleans it, thereby increasing its cleaning effect.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a resistance wire 310 is provided at the bottom of the furnace 110, and a platform 300 is provided above the resistance wire 310. First water inlet channels 320 are fixedly connected to both sides of the platform 300, and a second water inlet channel 321 is fixedly connected to the side of the platform 300 near the inside of the furnace 110. The two first water inlet channels 320 are slidably connected to the furnace 110.

[0030] In this embodiment, the bottom walls of the two first water inlet channels 320 are inclined outward from the depth of the furnace 110, and the bottom of the second water inlet channel 321 is inclined to both sides from the middle, with both ends of the second water inlet channel 321 located above the first water inlet channel 320.

[0031] When using this utility model, the prepared sample is placed in a high-temperature resistant container, then placed on the stage 300, the furnace door is closed, and the temperature control system 200 is started to heat the sample according to the pre-set temperature. After the sample is heated, the furnace door is opened and the sample is allowed to cool naturally before it is taken out. After the sample is taken out, the furnace chamber 110 needs to be cleaned.

[0032] By adjusting the folding rod 500, the cleaning mechanism 400 is placed in the appropriate position inside the furnace 110. Then, the drive motor 413 is started. The drive motor 413 drives the reciprocating screw 411 to rotate. The rotation of the reciprocating screw 411 drives the second scraper 430 to rotate, while simultaneously driving the threaded block 412 to move up and down. At the same time, the liquid storage tank 440 sprays the cleaning liquid through the nozzle. At this time, the three first scrapers 420 scrape the three side walls of the furnace 110, and the second scraper 430 scrapes the top wall of the furnace 110. When the first scrapers 420 move up and down, they will scrape the furnace... Waste and cleaning fluid on the wall are scraped off and fall into the first water inlet trough 320 through the through trough 421. The waste is then led out of the furnace 110 through the first water inlet trough 320. At the same time, the second scraper 430 scrapes off some cleaning fluid along with the waste and makes it fall into the second water inlet trough 321. The waste is then introduced into the second water inlet trough 321 and then led out of the furnace. After the furnace 110 is cleaned, the cleaning mechanism 400 is reset by adjusting the folding rod 500. Then the platform 300 and the two water inlets are pulled out of the furnace 110 for cleaning.

[0033] Note: The reciprocating screw 411 is represented by two threaded grooves with the same pitch and opposite directions, connected at both ends by a transition curve. The rotation of the reciprocating screw 411 causes the side of the helical groove to push the slider placed in the helical groove to perform axial reciprocating motion.

[0034] It should be noted that the drive motor 413 and reciprocating screw 411 mentioned above are devices with relatively mature existing technology. The specific model can be selected according to actual needs. At the same time, the drive motor 413 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
