[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] In some embodiments, it includes a first vertical plate 1, a second vertical plate 2 and a dustproof pipe 3, the dustproof pipe 3 is horizontally arranged, the two ends of the dustproof pipe 3 are detachably connected to the first vertical plate 1 and the second vertical plate 2 respectively, and the bottom of the dustproof pipe 3 is connected to a first discharge valve 301; A screening component for screening washing powder is coaxially arranged in the inner cavity of the dustproof pipe 3, and both ends of the screening component are rotatably connected to the first vertical plate 1 and the second vertical plate 2 respectively; A pushing assembly is coaxially arranged inside the screening assembly for pushing the washing powder to move along the axial direction of the screening assembly; A auger conveyor 4 is provided on one side of the first vertical plate 1 away from the dustproof pipe 3, and the auger conveyor 4 is connected to one end of the screening assembly and rotates in cooperation with it; A temporary storage chamber 5 is detachably connected to one side of the second vertical plate 2 away from the dustproof pipe 3. The temporary storage chamber 5 is connected to the screening assembly, and a second discharge valve 501 is connected to the bottom of the temporary storage chamber 5. A driving assembly is arranged on one side of the first vertical plate 1 away from the dustproof pipe 3 , and the driving assembly is transmission-connected with the screening assembly.

[0023] The dustproof pipe 3 is used to seal the periphery of the screening component, and the auger conveyor 4 and the temporary storage chamber 5 respectively seal the two ends of the screening component, thereby preventing a large amount of fine washing powder dust from diffusing into the air during the screening process.

[0024] The top of the hopper of the auger conveyor 4 is provided with a flange, which can be connected to an external feeder, so as to prevent the dust generated during the feeding process from being diffused into the air. The other parts of the auger conveyor 4 belong to the prior art and will not be described here.

[0025] The auger conveyor 4 conveys the washing powder to be screened into the screening component, and the driving component drives the screening component to rotate, and the screening component screens the washing powder, and the washing powder particles that meet the specifications are screened out of the screening component and fall into the dustproof pipe 3. At the same time, the pushing component pushes the washing powder to the end of the screening component away from the auger conveyor 4, using the method of screening and pushing. Finally, the large particles of washing powder or agglomerates that cannot be screened out by the screening component enter the temporary storage chamber 5. During the screening process, the first discharge valve 301 and the second discharge valve 501 are both closed to prevent dust from coming out. After the screening is completed, the first discharge valve 301 and the second discharge valve 501 can be opened to discharge the washing powder; the washing powder discharged from the temporary storage chamber 5 can be crushed again and then re-screened.

[0026] Since the temporary storage chamber 5 is detachably connected to the second vertical plate 2, and the dustproof tube 3 is detachably connected to the first vertical plate 1 and the second vertical plate 2, after a period of use, the worker can remove the temporary storage chamber 5 and the dustproof tube 3 to collect the washing powder attached to the inner walls of the two.

[0027] The dustproof pipe 3 is detachably connected to the first vertical plate 1 and the second vertical plate 2 by means of flange bolts. The temporary storage chamber 5 is also detachably connected to the second vertical plate 2 by means of flange bolts.

[0028] In some embodiments, the screening assembly includes a screen drum 6, a fixing ring 7, an annular plate 8, an extension tube 9 and a transmission tube 10. Two fixing rings 7 are provided, and the two fixing rings 7 are coaxially fixed at both ends of the screen drum 6; the fixing ring 7 away from the second vertical plate 2 is integrally formed with the annular plate 8, and the other fixing ring 7 is integrally formed with the extension tube 9, and one end of the extension tube 9 away from the screen drum 6 extends into the temporary storage chamber 5; the transmission tube 10 is integrally formed with the annular plate 8, and one end of the transmission tube 10 extends out of the first vertical plate 1 and is connected to the driving assembly in a transmission manner. Bearings, such as dustproof bearings, are respectively installed on the opposite surfaces of the first vertical plate 1 and the second vertical plate 2, and the inner rings of the two dustproof bearings are respectively interference fit with the annular plate 8 and the extension tube 9, so that the screening assembly is rotatably mounted on the first vertical plate 1 and the second vertical plate 2. The setting of the bearings can avoid direct contact between the screening assembly and the first vertical plate 1 and the second vertical plate 2, thereby reducing the resistance of the screening assembly when rotating.

[0029] In some embodiments, the discharge pipe of the auger conveyor 4 is inserted into the transmission pipe 10, and the discharge pipe is rotatably matched with the transmission pipe 10. A first sealing ring can be provided between the discharge pipe and the inner wall of the transmission pipe 10 to prevent dust from floating out during the screening process.

[0030] In some embodiments, the pusher assembly includes a spiral plate 11, and the spiral plate 11 is coaxially fixed on the inner wall of the screen drum 6. Through the above arrangement, the spiral plate 11 can rotate with the screen drum 6, and when the spiral plate 11 rotates, the washing powder can be pushed.

[0031] A screening method: During the screening process, the screening component rotates n times and then rotates in the opposite direction n times, and repeats this process multiple times, wherein n is less than the number of spiral turns of the spiral plate 11. By means of the above method, it is possible to ensure that the washing powder is fully screened; if n is less than the number of spiral turns of the spiral plate 11, it is ensured that the washing powder will not enter the temporary storage chamber 5 before being fully screened.

[0032] In some embodiments, the temporary storage chamber 5 includes a cover body 502 , which is detachably connected to the second vertical plate 2 , and the cover body 502 covers the extension pipe 9 , and the second discharge valve 501 is installed at the bottom of the cover body 502 .

[0033] In some embodiments, the driving assembly includes a reduction motor 12, a driving wheel, a driven wheel and a transmission component 13. A support plate 14 is fixed to the side of the first vertical plate 1 away from the dustproof tube 3. The reduction motor 12 is fixedly connected to the support plate 14. The driving wheel is fixedly connected to the output shaft of the reduction motor 12. The driven wheel is fixed to the outer wall of the transmission tube 10. One end of the transmission component 13 is sleeved on the driving wheel, and the other end of the transmission component 13 is sleeved on the driven wheel. The reduction motor 12 drives the driving wheel to rotate, and the driving wheel drives the driven wheel to rotate through the transmission component 13. The driven wheel drives the transmission tube 10 to rotate, and the screening assembly can rotate. The transmission component 13 can be a transmission belt or a chain, and the corresponding driving wheel and driven wheel are transmission pulleys or sprockets.

[0034] In some embodiments, a support plate 14 is fixed to a side of the first vertical plate 1 away from the dustproof tube 3 , and a plurality of legs are fixed to an outer wall of the auger conveyor 4 , and the legs are fixedly connected to the support plate 14 .

[0035] In some embodiments, the diameter of the dustproof pipe 3 gradually decreases from the middle to both ends. Through the above arrangement, it is convenient for the washing powder entering the dustproof pipe 3 to gather, so as to be discharged from the first discharge valve 301.

[0036] In some embodiments, the dustproof tube 3 includes an upper semicircular tube 302 and a lower semicircular tube 303, and the upper semicircular tube 302 is detachably connected to the lower semicircular tube 303. Through the above arrangement, it is convenient to disassemble the dustproof tube 3. The upper semicircular tube 302 and the lower semicircular tube 303 are integrally formed with a fixing plate on the opposite surface, and a through hole is opened on the fixing plate, and the fixing plate of the upper semicircular tube 302 is bolted to the fixing plate of the lower semicircular tube 303.

[0037] In some embodiments, the inner walls at both ends of the dustproof tube 3 are respectively rotatably matched with two fixing rings 7. A second sealing ring can be provided at the rotatably matched position between the dustproof tube 3 and the fixing ring 7 to prevent dust from adversely affecting the bearings on the first vertical plate 1 and the second vertical plate 2.

[0038] The working principle of the screening device for washing powder production of the present invention is as follows: the dustproof pipe 3 is used to seal the surrounding side of the screening component, the auger and the auger shaft in the auger conveyor 4 seal one end of the screening component, and the temporary storage chamber 5 seals the other end of the screening component, thereby preventing a large amount of fine washing powder dust from diffusing into the air during the screening process.

[0039] The auger conveyor 4 conveys the washing powder to be screened into the screen drum 6, the reduction motor 12 drives the driving wheel to rotate, the driving wheel drives the driven wheel to rotate through the transmission component 13, the driven wheel drives the transmission pipe 10 to rotate, and the screening component can rotate, and the screen drum 6 screens the washing powder, and the washing powder particles that meet the specifications are screened out of the screen drum 6 and fall into the dustproof pipe 3. At the same time, the spiral plate 11 can rotate with the screen drum 6. When the spiral plate 11 rotates, the washing powder can be pushed, and the method of screening and pushing is adopted. Finally, the large-particle washing powder or agglomerates that cannot be screened out by the screen drum 6 enters the temporary storage chamber 5. After the screening is completed, the first discharge valve 301 and the second discharge valve 501 can be opened to discharge the washing powder.
