Description

Technical Field

[0001] The utility model relates to the technical field of battery material production, in particular to a sagger detection device and kiln equipment. Background Art

[0002] During the production process of lithium iron phosphate batteries, lithium iron phosphate powder needs to be loaded into a sagger and transported to a sintering kiln for sintering. During the sintering period, a large amount of exhaust gas and tar generated by the kiln cannot be effectively discharged, so that the exhaust gas and tar flow into the replacement chamber, causing the glass mirror surface of the photoelectric sensor in the replacement chamber to become dirty, which can easily cause false detection of the photoelectric sensor, that is, the photoelectric sensor cannot normally detect whether the sagger transportation has arrived at the predetermined position normally.

[0003] For example, Chinese patent document CN213633868U discloses an infrared detection device for kilns that is easy to clean, which includes a detection pipeline, a light-transmitting protective lens, an infrared transceiver, and a bracket for fixing the infrared transceiver. The detection pipeline is vertically connected and arranged on the side wall of the kiln. The light-transmitting protective lens is arranged at one end of the detection pipeline away from the kiln. The infrared rays emitted by the infrared transceiver pass through the light-transmitting protective lens and the detection pipeline in turn and enter the kiln. A ventilation pipe is connected to the detection pipeline, and the other end of the ventilation pipe is connected to the air source. A valve is provided on the ventilation pipe. This technical solution ventilates the inside of the detection pipeline through the ventilation pipe to blow away the dust accumulated on the detection pipeline. It is simple to operate, convenient for users to use, and ensures the normal detection work of the infrared detection device.

[0004] However, the technical solution disclosed in the above patent still has the following problems: the technical solution disclosed in the above patent does not provide a structure or device for cleaning the tar on the light-transmitting protective lens. Therefore, when the tar adheres to the inner wall of the detection pipeline and the light-transmitting protective lens through the kiln, it will seriously affect the detection accuracy of the infrared transceiver. Therefore, it can only be processed by replacing the light-transmitting protective lens, thereby reducing the utilization rate of a single light-transmitting protective lens and poor reliability of use, thus failing to ensure normal detection needs.

[0005] Therefore, there is an urgent need for a device that can efficiently clean the oil stains on the surface of the glass mirror of the photoelectric sensor and ensure the normal detection of the photoelectric sensor. Utility Model Content

The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0039] See also Figures 1 to 6 In order to better understand the sagger detection device 10 of the present application, the sagger detection device 10 is further explained below:

[0040] The sagger detection device 10 of one embodiment includes a photoelectric sensor 100 and a cleaning mechanism 200, wherein the photoelectric sensor 100 is fixedly mounted on the inner wall of the replacement chamber 600. The cleaning mechanism 200 includes a driving component 210, a cleaning component 220 and a cleaning agent inlet pipe 230, wherein the driving component 210 is mounted on the inner wall of the replacement chamber 600, a power output end of the driving component 210 is connected to the cleaning component 220, the driving component 210 drives the cleaning component 220 to reciprocate relative to the photoelectric sensor 100, and the cleaning agent inlet pipe 230 is connected to the cleaning component 220.

[0041] In this embodiment, the cleaning agent is transported to the cleaning component 220 through the cleaning agent inlet pipe 230, so that the cleaning agent can fully infiltrate the cleaning end of the cleaning component 220; the driving component 210 then drives the cleaning component 220 to move back and forth relative to the photoelectric sensor 100 to wipe the mirror surface of the photoelectric sensor 100, so as to efficiently remove the oil stains attached to the mirror surface of the photoelectric sensor 100, improve the clarity of the mirror of the photoelectric sensor 100, so that the photoelectric sensor 100 can normally send and receive infrared light, thereby effectively ensuring that the photoelectric sensor 100 can normally detect the transportation of the sagger through the replacement chamber 600.

[0042] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, a fixed support 610 is protruded from the inner wall of the replacement chamber 600; the driving component 210 includes a driving member 2110 and a telescopic shaft 2120; the driving member 2110 is installed and fixed on the fixed support 610, and the power end of the driving member 2110 is connected to the cleaning component 220 through the telescopic shaft 2120.

[0043] In one embodiment, the cleaning assembly 220 includes a cleaning body 2210 and a cleaning box 2220; the cleaning box 2220 is provided with a first opening 2222 and a liquid storage cavity 2224 which are connected to each other, a portion of the cleaning body 2210 is located in the liquid storage cavity 2224, the cleaning end of the cleaning body 2210 is protruded from the first opening 2222, the cleaning box 2220 is connected to the cleaning agent inlet pipe 230, and the telescopic shaft (2120) is fixedly connected to the outer wall of the cleaning box 2220.

[0044] It can be understood that in this embodiment, the driving member 2110 is a driving cylinder, so that the cleaning box 2220 is driven to reciprocate through the telescopic shaft 2120 of the driving cylinder, so that the cleaning end of the cleaning body 2210 slides and wipes the mirror surface of the photoelectric sensor 100. In other embodiments, the driving member 2110 can also be a driving hydraulic cylinder, an electric cylinder and a reciprocating motor as power; in order to reduce the influence of the temperature of the replacement chamber 600 on the operation of the driving member 2110, the driving member 2110 can also be set on the outer wall of the replacement chamber 600 to ensure the normal use of the driving member 2110.

[0045] It can be understood that in this embodiment, the cleaning box 2220 is an integrated structure, so that the cleaning box 2220 has a good structural strength, so that the cleaning body 2210 can be fixed more reliably; wherein, the cleaning body 2210 can be a cleaning sponge; the liquid inlet end of the cleaning agent inlet pipe 230 is connected to the cleaning agent storage tank, and the liquid outlet end of the cleaning agent inlet pipe 230 injects the cleaning agent into the top of the cleaning box 2220, so that the cleaning agent fully infiltrates the cleaning sponge, and the excess cleaning agent flows into the liquid storage chamber 2224 for storage, which can avoid the waste of cleaning agent; at the same time, one end of the cleaning sponge is always immersed in the cleaning agent in the liquid storage chamber 2224, so that when it is necessary to clean the oil stains on the surface of the mirror of the photoelectric sensor 100, the driving cylinder can drive the cleaning end of the cleaning sponge to quickly and efficiently clean the oil stains on the surface of the mirror, so as to ensure the clarity of the mirror of the photoelectric sensor 100 at all times. When the cleaning sponge is seriously aged and needs to be replaced, the cleaning box 2220 can also be disassembled from the movable telescopic end of the driving cylinder for corresponding replacement.

[0046] like Figure 1 , Figure 2 and Figure 4 As shown, in one embodiment, the sagger detection device 10 also includes a decontamination component 300, and the decontamination component 300 includes a decontamination wipe plate 310 and a sprayer 320; the decontamination wipe plate 310 and the sprayer 320 are both fixed to the inner wall of the replacement chamber 600, and the spray hole (not shown) of the sprayer 320 is arranged toward the decontamination wipe plate 310; the decontamination wipe plate 310 is located on the path where the driving component 210 drives the cleaning box 2220 to move back and forth relative to the photoelectric sensor 100, so that the cleaning end of the cleaning body 2210 slides through the decontamination wipe plate 310.

[0047] It is understandable that after the cleaning end of the cleaning body 2210 slides and wipes the mirror surface of the photoelectric sensor 100, there is oil attached to the cleaning end of the cleaning body 2210. At this time, the cleaning end of the cleaning body 2210 can be slid and wiped on the decontamination wiper 310, so that the decontamination wiper 310 can remove the oil attached to the cleaning end of the cleaning body 2210, so as to avoid affecting the cleaning effect of the cleaning end of the cleaning body 2210 sliding and wiping the mirror surface of the photoelectric sensor 100 next time. At the same time, the sprayer 320 located above the decontamination wiper 310 can spray the decontamination detergent toward the decontamination wiper 310 through the spray hole (not shown), so that the decontamination wiper 310 can provide a decontamination effect for the cleaning end of the cleaning body 2210 in a reciprocating cycle. In this embodiment, the number of the decontamination wipers 310 is three, and in other embodiments, the number of the decontamination wipers 310 is at least one.

[0048] Figures 2 to 5As shown, in one embodiment, the sprayer 320 is located above the decontamination wiper 310; the decontamination assembly 300 also includes a washing inlet pipe 330, and the sprayer 320 is connected to the liquid outlet end of the washing inlet pipe 330.

[0049] In one embodiment, the sagger detection device 10 also includes a dirt collecting component 400, which includes a connected dirt collecting tank 410 and a drain pipe 420, the dirt collecting tank 410 is fixed to the inner wall of the replacement chamber 600, the dirt collecting tank 410 is located below the decontamination wipe plate 310, and the notch of the dirt collecting tank 410 is opened toward the decontamination wipe plate 310.

[0050] In this embodiment, the liquid inlet end of the washing inlet pipe 330 is connected to the detergent storage tank. It is understandable that the detergent sprayed from the spray hole (not shown) of the sprayer 320 for cleaning flows into the dirt collection tank 410 and the sewage pipe 420 below the dirt removal wiper 310 by gravity after cleaning the dirt removal wiper 310; wherein, the size of the notch of the dirt collection tank 410 can cover the bottom of the photoelectric sensor 100, the dirt removal wiper 310 and the cleaning box 2220, so as to avoid the pollution problem of the replacement chamber 600 caused by the outflow of dirt and other liquids.

[0051] See also Figures 2 to 6 The present application also provides a kiln equipment 20, including any of the above-mentioned sagger detection devices 10, the kiln equipment 20 also includes a sintering kiln 500, a replacement chamber 600, a first insulation box 700 and a second insulation box 800; the replacement chamber 600 is provided with a sagger conveying channel 601, and the first insulation box 700 and the second insulation box 800 are arranged in sequence along the sagger conveying channel 601; the replacement chamber 600 includes a first replacement chamber 602 and a second replacement chamber 603, the second replacement chamber 603 is connected to the sintering kiln 500, the first insulation box 700 is located between the first replacement chamber 602 and the second replacement chamber 603, and the second insulation box 800 is located at the position where the second replacement chamber 603 is connected to the sintering kiln 500.

[0052] In one embodiment, the first insulation box body 700 includes a first support box seat 710, a first movable partition 720 and a first cylinder driving member 730; the first support box seat 710 is provided with a first insulation cavity 7101, the first cylinder driving member 730 is arranged in the first insulation cavity 7101, the movable telescopic end of the first cylinder driving member 730 is connected to one end of the first movable partition 720, and the other end of the first movable partition 720 extends into the replacement chamber 600.

[0053] In one embodiment, the second insulation box body 800 includes a second support box seat 810, a second movable partition 820 and a second cylinder driving member 830; the second support box seat 810 is provided with a second insulation chamber 8101, the second cylinder driving member 830 is arranged in the second insulation chamber 8101, the movable telescopic end of the second cylinder driving member 830 is connected to one end of the second movable partition 820, and the other end of the second movable partition 820 extends into the second replacement chamber 603.

[0054] In this embodiment, the sagger loaded with positive electrode materials passes through the sagger conveying channel 601 from left to right (the specific direction can be referred to Figure 3 As shown in FIG. 5 , the sagger passes through the first displacement chamber 602 and the second displacement chamber 603 in sequence, and is then transported to the sintering kiln 500. It can be understood that when the sagger is transported by the rotating roller and is ready to enter the second displacement chamber 603 through the sagger conveying channel 601, the first cylinder driving member 730 drives the first movable partition 720 to rise, so that the sagger enters the second displacement chamber 603 normally, and at this time, the first cylinder driving member 730 drives the first movable partition 720 to descend; when the sagger is ready to enter the sintering kiln 500, the second cylinder driving member 830 drives the second movable partition 820 to rise, so that the sagger enters the sintering kiln 500 smoothly.

[0055] At the same time, since the sagger conveying passage 601 is in the area of ​​hot and cold air convection, that is, the air temperature in the sintering kiln 500 is higher than the air temperature in the first displacement chamber 602 and the second displacement chamber 603, when the second displacement chamber 603 is connected to the sintering kiln 500 and the first displacement chamber 602 is connected to the second displacement chamber 603, the hot air in the sintering kiln 500 carries the waste gas and tar into the second displacement chamber 603 and the first displacement chamber 602, thereby causing the mirror surface of the photoelectric sensor 100 in the displacement chamber 600 to become dirty. By setting the first displacement chamber 602 and the second displacement chamber 603, the rate of hot air circulation can be effectively avoided, and the influence of waste gas and tar on the normal detection of the photoelectric sensor 100 can be reduced. In other embodiments, dust extraction devices (not shown) are respectively provided at the top of the first replacement chamber 602 and the second replacement chamber 603, and dust in the first replacement chamber 602 and the second replacement chamber 603 are extracted by the dust extraction devices (not shown) to reduce the effect of hot air carrying dust on the mirror surface of the photoelectric sensor 100.

[0056] like Figures 2 to 6As shown, in one embodiment, the kiln equipment 20 also includes a first jet trough 900 and a second jet trough 1000; the number of photoelectric sensors 100 is two, one of which is located in the first displacement chamber 602, and the other photoelectric sensor 100 is located in the second displacement chamber 603; the control end of the first jet trough 900 and the control end of the second jet trough 1000 are electrically connected to the two photoelectric sensors 100 respectively; the first jet trough 900 is installed and fixed on the inner top wall of the first displacement chamber 602, and the first jet outlet 901 is opened at the gas outlet end of the first jet trough 900; the second jet trough 1000 is installed and fixed on the inner top wall of the second displacement chamber 603, and the second jet outlet 1001 is opened at the gas outlet end of the second jet trough 1000.

[0057] It should be noted that, in the present embodiment, the photoelectric sensor 100 is specifically a photoelectric sensor 100 integrating an infrared transmitter and an infrared receiver. Therefore, a photoelectric sensor 100 is installed on the inner wall of the first displacement chamber 602 and the inner wall of the second displacement chamber 603, and the photoelectric sensor 100 in the first displacement chamber 602 is respectively connected to the first cylinder driving member 730 and the first jet slot 900, so that the lifting and lowering movement of the first movable partition 720 is controlled by the first cylinder driving member 730 to realize the connection and isolation between the first displacement chamber 602 and the second displacement chamber 603; and the first jet slot 900 is controlled to realize the first jet port 901 to output air or other flame-retardant gas downward to form an air curtain with an isolation effect, and blow away the exhaust gas in the sensing area of ​​the photoelectric sensor 100 to avoid erroneous sensing of the photoelectric sensor 100 due to excessive exhaust gas concentration.

[0058] Similarly, in this embodiment, the photoelectric sensor 100 and the second jetting slot 1000 in the second displacement chamber 603 have the same functions and effects as the first jetting slot 900, and will not be described in detail herein.

[0059] It is understood that in other embodiments, the photoelectric sensor 100 can be specifically divided into an infrared transmitter and an infrared receiver (such as Figure 5 As shown), therefore, the user can set the cleaning mechanism 200, the decontamination component 300 and the dirt collecting component 300 according to the number of infrared transmitters and infrared receivers to meet the cleaning requirements of the mirror surface of the infrared transmitter and the infrared receiver respectively.

[0060] The working principle of the kiln equipment 20 is as follows: the photoelectric sensor 100 in the first displacement chamber 602 emits infrared light toward the sagger conveying channel 601. When it senses that a sagger passes through the sagger conveying channel 601, the photoelectric sensor 100 sends an electrical signal to the first cylinder driving member 730 to control the first movable partition 720 to rise, so that the first displacement chamber 602 is connected with the second displacement chamber 603, that is, the sagger can pass normally and enter the second displacement chamber 603. Finally, the first movable partition 720 It descends to isolate the first displacement chamber 602 from the second displacement chamber 603; similarly, when the photoelectric sensor 100 in the second displacement chamber 603 senses the passage of the sagger, the photoelectric sensor 100 sends an electrical signal to the second cylinder driving member 830 to control the second movable partition 820 to rise, so that the second displacement chamber 603 and the sintering kiln 500 are connected, that is, the sagger can pass normally and enter the sintering kiln 500, and finally the second movable partition 820 descends to isolate the second displacement chamber 603 from the sintering kiln 500. Through the orderly lifting and lowering action of the first movable baffle 720 and the second movable baffle 820 mentioned above, the balance of the air pressure switching in the first displacement chamber 602 and the second displacement chamber 603, and the balance of the air pressure switching in the second displacement chamber 603 and the sintering kiln 500 are effectively ensured when the sagger passes through the first displacement chamber 602 and the second displacement chamber 603, thereby effectively reducing the flow rate of exhaust gas and tar in the first displacement chamber 602 and the second displacement chamber 603, thereby effectively reducing the influence of exhaust gas and tar on the normal detection of the photoelectric sensor 100.

[0061] It should be noted that the kiln equipment 20 of the present disclosure only protects the telecommunication connection relationship between each component and the photoelectric sensor 100, and the electrical control method of the photoelectric sensor 100 belongs to the prior art and is not within the protection scope of the present disclosure.

[0062] Compared with the prior art, the utility model includes but is not limited to the following advantages:

[0063] 1. Detergent is delivered to the cleaning component 220 through the detergent inlet pipe 230, so that the detergent can fully infiltrate the cleaning end of the cleaning component 220; then the driving component 210 drives the cleaning component 220 to move back and forth relative to the photoelectric sensor 100 to wipe the surface of the sight glass of the photoelectric sensor 100, so as to efficiently remove the oil stains attached to the surface of the sight glass of the photoelectric sensor 100, improve the clarity of the sight glass of the photoelectric sensor 100, so that the photoelectric sensor 100 can normally send and receive infrared light, thereby effectively ensuring that the photoelectric sensor 100 can normally detect the transportation of the sagger through the replacement chamber 600.

[0064] 2. The liquid inlet end of the detergent inlet pipe 230 is connected to the detergent storage tank, and the liquid outlet end of the detergent inlet pipe 230 injects detergent into the top of the cleaning box 2220, so that the detergent fully soaks the cleaning sponge, and the excess detergent flows into the liquid storage cavity 2224 for storage, which can avoid the waste of detergent.

[0065] 3. The cleaning end of the cleaning body 2210 slides and rubs on the decontamination wiping plate 310, so that the decontamination wiping plate 310 can remove the oil attached to the cleaning end of the cleaning body 2210, so as to avoid affecting the cleaning effect of the cleaning end of the cleaning body 2210 sliding and wiping the mirror surface of the photoelectric sensor 100 next time.
