[0034] like Figures 1 to 6 As shown, an environmentally friendly smoke collection device for negative electrode material production includes a collection tank 1, a filter assembly 2, a cleaning assembly 3, and a sealing cover 4; a cavity 11 is opened in the collection tank 1, and a smoke inlet hole 12 and a smoke outlet hole 13 are opened on the side wall of the collection tank 1; the filter assembly 2 is provided with two groups, and the filter assembly 2 is arranged between the smoke inlet hole 12 and the smoke outlet hole 13, one end of the filter assembly 2 is rotatably connected to the side wall of the collection tank 1, and the other end is provided with a rotating shaft 21, and the two groups of the filter assembly 2 are hinged to each other through the rotating shaft 21, and the filter assembly 2 filters the smoke in the cavity 11; the cleaning assembly 3 is provided with two The cleaning component 3 is arranged to slide in the horizontal direction below the filter component 2; the sealing cover 4 is arranged on the top of the collection tank 1, and a cylinder 41 is arranged on the top of the sealing cover 4. The push rod of the cylinder 41 penetrates the sealing cover 4 and extends into the cavity 11 and is connected to the rotating shaft 21. The push rod of the cylinder 41 moves in the vertical direction to drive the filter component 2 to switch from a horizontal state to an inclined state. When the filter component 2 tilts downward, it squeezes the cleaning component 3 below. The cleaning component 3 slides to both sides under the squeezing force and passes through the lower end surface of the filter component 2 to complete the cleaning of the filter component 2.

[0035] like Figure 2 , 3 As shown in Figure 4, the filter assembly 2 also includes a filter plate 22, a first filter screen 23, and a second filter screen 24; the filter plate 22 is symmetrically arranged in two groups, which are rotatably connected to the side walls of the collection tank 1 respectively; the first filter screen 23 and the second filter screen 24 are sleeved on the filter plate 22, and the first filter screen 23 and the second filter screen 24 are hinged through the rotating shaft 21.

[0036] It should be noted here that when the first filter screen 23 and the second filter screen 24 are driven by the push rod of the cylinder 41 to switch from a horizontal state to an inclined state, the first filter screen 23 and the second filter screen 24 slide relative to their respective filter core plates 22, and the filter core plate 22 rotates around the connection point on the side wall of the collection tank 1.

[0037] like Figure 2 , 3 As shown in Figure 4, the contact areas of the first filter screen 23 and the second filter screen 24 are staggered and interlocked, and the contact surface is in an arc shape.

[0038] It is worth mentioning that, by setting the contact surface of the first filter 23 and the second filter 24 to be arc-shaped, interference will not occur while ensuring the fit, thus avoiding the rotation restriction at the hinge.

[0039] like Figure 2As shown, filter holes 25 are arranged on the filter core plate 22 , the first filter screen 23 and the second filter screen 24 .

[0040] It is worth mentioning that, by providing filter holes on the filter plate 22 , the filter plate 22 can support the first filter screen 23 and the second filter screen 24 without affecting the filtering of the smoke.

[0041] like Figure 1 , 3 As shown in , 4 and 6, the cleaning component 3 is symmetrically arranged in two groups, and the cleaning component 3 includes a slide groove 31, a slider 32 and a spring 33; the slide groove 31 is opened on both sides of the inner wall of the collection tank 1; the slider 32 is slidably arranged in the slide groove 31, and a brush 321 is arranged on the slider 32; the spring 33 is arranged in the slide groove 31, and the two ends of the spring 33 are respectively connected to the side wall of the collection tank 1 and the slider 32.

[0042] It is worth mentioning here that a slide groove 31 is provided on the side wall of the collection tank 1, which can limit the slider 32 to horizontal movement only, and prevent the slider 32 from turning over when squeezed by the first filter 23 and the second filter 24; the spring 33 arranged in the slide groove 31 provides a spring force to the slider 32 during the process of the first filter 23 and the second filter 24 switching back to the horizontal state, and pushes the slider 32 back to the initial position; the brush 33 is always in contact with the bottom surface of the first filter 23 and the second filter 24 during the reciprocating movement of the slider 32, and sweeps the filter holes 25 on the bottom surface to brush off the blocked particulate dust.

[0043] like Figure 3 , 4 As shown, the upper end surface of the slider 32 is inclined, and the inclined surface near the central position is lower.

[0044] It is worth mentioning that the upper end surface of the slider 32 is tilted to facilitate squeezing the slider 32 toward both sides when the first filter screen 23 and the second filter screen 24 are tilted.

[0045] like Figure 1 As shown, a smoke inlet 12 and a smoke outlet 13 are provided on the collecting tank 1. The smoke inlet 12 is located below the filter assembly 2, and the smoke outlet 13 is located above the filter assembly.

[0046] It is worth mentioning here that setting the smoke inlet 12 below the filter assembly 2 and the smoke outlet 13 above the filter assembly is more in line with the upward flow direction of hot air, making the smoke flow in the collection tank smoother and improving the efficiency of smoke filtration.

[0047] It should be noted that guide fans are provided at both the smoke inlet 12 and the smoke outlet 13 .

[0048] like Figure 1 , 7 As shown, a base 14 is disposed at the bottom of the collecting tank 1 , and a collecting box 15 is disposed in the base 14 .

[0049] It is worth mentioning here that the collection box 15 is slidably arranged in the base 14, so that it is convenient to manually pull out the collection box 15 to process the collected dust particles.

[0050] like Figure 1 As shown, the bottom of the collecting tank 1 is in an inverted step-shaped shape, and a discharge port 16 is opened at the bottom of the collecting tank 1 , and the discharge port 16 is connected to the cavity 11 and the collecting box 15 .

[0051] It is worth mentioning here that the bottom of the collection tank 1 is arranged in an inverted step and has a discharge port 16, so that the smoke particles left after filtering can be better gathered and collected, reducing the smoke particles remaining in the collection tank 1 and alleviating the later manual cleaning work of the collection tank 1.

[0052] The working process is as follows:

[0053] The flue gas generated during the processing of the negative electrode material is driven by the guide fan to enter the cavity 11 in the collection tank 1 from the smoke inlet 12, and the guide fan at the smoke outlet 13 drives the smoke in the cavity 11 to rush out of the smoke outlet and be discharged. During the flow of the flue gas, it passes through the filter component 2, and the dust particles in the flue gas are filtered out. Some of the dust particles fall into the collection box through the discharge port 16, and some of the dust particles remain on the filtering surface of the lower end surface of the first filter 23 and the second filter 24.

[0054] After working for a certain period of time, the cylinder 41 is started, and the push rod of the cylinder 41 drives the filter assembly to switch from a horizontal state to an inclined state. When the first filter screen 23 and the second filter screen 24 tilt downward, they squeeze the slider 32 below, and the slider 32 slides to both sides under the squeezing force. When the push rod of the cylinder 41 is retracted, the first filter screen 23 and the second filter screen 24 switch back to a horizontal state, and the spring 33 pushes the slider 32 back to its initial position; the brush 33 always contacts the bottom surface of the first filter screen 23 and the second filter screen 24 during the reciprocating motion of the slider 32, sweeps the filter holes 25 on the bottom surface, and brushes off the blocked particle dust and drops it into the collection box 15.

[0055] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
