Description

Technical Field

[0001] The utility model relates to the field of coal detection instruments, in particular to an industrial analyzer. Background Art

[0002] At present, industrial analyzers are mainly used to determine the moisture, ash and volatile content in coal. The instrument has a high degree of automation and can automatically complete the experiment after the sample is set out. During the whole process, there is no need to open the crucible cover or replace the crucible in the middle. The experiment can be started as soon as the instrument is turned on.

[0003] Industrial analyzers use electronic balances to weigh sample coal. The electronic balance is installed in the lower space of the furnace away from the heat source. The sample is weighed by extending the weighing push rod into the sample tray inside the furnace. When weighing, the sample tray is controlled to fall by the manipulator, and then the sample crucible falls on the weighing push rod with a small disc to complete the weighing. Any part of the weighing push rod with a small disc connected to the electronic balance cannot touch the furnace tray to ensure the accurate weighing of the electronic balance. This creates a certain gap between the high-temperature combustion furnace and the lower weighing space, so that the coal gas overflows into the lower space of the furnace during coal ash analysis, and then is discharged to the laboratory through the cooling fan, causing laboratory air pollution, which can seriously lead to chronic poisoning of experimenters.

[0022] The technical solution of the utility model will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] like Figure 1The figure shows a specific embodiment of the industrial analyzer provided by the utility model, which is used to measure the ash content in coal, and includes an analyzer housing 100, wherein a furnace plate 101 is arranged in the analyzer housing 100, and the furnace plate 101 divides the analyzer housing 100 into a combustion zone 100a located at the upper side and a detection zone 100b located at the lower side; the combustion zone 100a is provided with an exhaust port 100c connected to an exhaust assembly 200, and the smoke of the combustion zone 100a is discharged along the exhaust assembly 200. 0 is discharged to the outside; the detection area 100b is provided with an air inlet 100d, and the air inlet 100d is connected to the air inlet assembly 300; a weighing device 400 is located inside the analyzer housing 100, and the weighing device 400 includes a weighing plate 401 located in the combustion area 100a, a weighing detection body 402 located in the detection area 100b, and a weighing rod 403 connected to the weighing plate 401 at one end and the weighing detection body 402 at the other end, and the weighing rod 403 is penetrated on the furnace plate 101.

[0027] The above-mentioned industrial analyzer is configured with an air inlet 100d in the detection zone 100b and connected to the air inlet assembly 300, and an air exhaust port 100c is configured in the combustion zone 100a and connected to the exhaust assembly 200, wherein the air inlet pressure of the air inlet assembly 300 is greater than or equal to the exhaust pressure of the exhaust assembly 200; it can prevent the smoke in the combustion zone 100a from entering the detection zone 100b, thereby preventing the laboratory outside the detection zone 100b from being contaminated by the smoke.

[0028] Specifically, in an optional embodiment, the exhaust assembly 200 includes an exhaust duct 201 extending to the outdoors and an exhaust fan 202 installed on the exhaust duct 201, and the exhaust pressure is controlled by controlling the exhaust fan 202. More specifically, the exhaust duct 201 is provided with a first air pressure sensor 203 for detecting the exhaust pressure.

[0029] Specifically, in an optional implementation manner, Figure 1 As shown, the air inlet assembly 300 includes an air inlet duct 301 and a suction pump 302 located on the air inlet duct 301. The suction pump 302 is located in the laboratory and draws air to the detection area 100b. By controlling the output pressure of the suction pump 302, the detection area 100b has a slightly positive pressure environment, thereby preventing the smoke in the combustion area 100a from entering the detection area 100b through the perforations of the furnace plate 101.

[0030] Specifically, in another optional implementation, Figure 3As shown, the air inlet assembly 300 includes an air inlet duct 301, a pressure gas source 303 and a switch valve 304 located on the air inlet duct 301. The opening or closing of the air inlet assembly 300 can be controlled by controlling the switch valve 304, and the air pressure in the detection area 100b can be controlled by controlling the output pressure of the pressure gas source 303. More specifically, the pressure gas source 303 is an inert gas, and a pressure reducing valve 305 is further provided on the air inlet duct 301. The air pressure of the air inlet assembly 300 can be controlled by controlling the opening of the pressure reducing valve 305.

[0031] More specifically, the air inlet duct 301 is provided with a second air pressure sensor 306 for detecting the air inlet pressure.

[0032] Specifically, in an optional embodiment, the gap between the perforation on the furnace plate 101 of the above-mentioned industrial analyzer and the weighing rod 403 is between 5mm and 10mm. The above-mentioned gap range can ensure that the weighing rod 403 does not contact the furnace plate 101 during the up and down movement. At the same time, the above-mentioned smaller gap can also make the air flow velocity passing through the gap lower. Since the flue gas in the combustion zone 100a and the gas in the detection zone 100b will contact in this gap, when the gas flow rate is relatively small, the formation of a gas turbulence zone in this area can be avoided, which causes the weighing rod 403 to shake.

[0033] Specifically, in an optional embodiment, a protective sleeve 500 is further provided in the detection area 100b. The protective sleeve 500 is sleeved on the outer wall of the weighing rod 403 and spaced apart from the weighing rod 403, which can further prevent the wind pressure of the air inlet assembly 300 from acting on the weighing rod 403.

[0034] Specifically, Figure 2 As shown, the lower end of the protective sleeve 500 is fixedly connected to the weighing detection body 402, and the upper end of the protective sleeve 500 is spaced apart from the furnace plate 101. Specifically, the protective sleeve 500 includes a sleeve body 501, an annular baffle 502 located at the upper end of the sleeve body 501, and a connecting plate 503 located at the lower end of the sleeve body 501. The protective sleeve 500 is fixed by a fastening assembly penetrated through the connecting plate 503 and the weighing detection body 402. A spacing distance of 10mm-20mm is set between the annular baffle 502 on the upper side of the protective sleeve 500 and the furnace plate 101.

[0035] Specifically, in an optional embodiment, a barrier curtain 600 is provided between the annular baffle plate 502 and the furnace plate 101, and the barrier curtain 600 is configured as a shutter structure, the upper end of which is fixed on the furnace plate 101, and the lower end is a free end. The barrier curtain 600 can be made of a light material. Whether the inlet air pressure is appropriate can be judged according to the direction of the barrier curtain 600. For example, when the inlet air pressure is greater than the exhaust air pressure, the free end of the barrier curtain 600 tilts toward the direction close to the weighing rod 403, and vice versa, it tilts toward the direction away from the weighing rod 403. This facilitates the control of the inlet air pressure, so as to intuitively judge whether the inlet air pressure is appropriate.

[0036] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the present utility model.
