Description

Technical Field

[0001] This utility model relates to the field of laundry detergent production, specifically to a two-stage screening and impurity removal device for laundry detergent production. Background Technology

[0002] A laundry detergent vibrating screen is a piece of equipment specifically designed for the production of laundry detergent. It is primarily used for screening and grading raw materials. Laundry detergent vibrating screens typically employ vibrating screen technology, using vibration to sieve the raw materials onto a screen mesh to remove impurities, control particle size, and ensure the quality and uniformity of the laundry detergent product.

[0003] During the production and transportation of laundry detergent, clumping or foreign impurities may occur. In order to ensure the purity of the laundry detergent product, it is necessary to screen and remove impurities. Most existing screening equipment is a single screen cylinder structure, and the screen holes are prone to clogging during the screening process, requiring cleaning of the screen holes, which affects the screening efficiency and has shortcomings. Utility Model Content

[0004] (a) Purpose of the utility model

[0005] To address the technical problems existing in the background art, this utility model proposes a two-stage screening and impurity removal device for laundry detergent production, which features anti-clogging screening and improved screening quality.

[0008] The air separation mechanism includes a separation plate installed in the middle of the air separation table. The separation plate includes an inclined part and a horizontal part. A purging frame is provided below the inclined part. A purging table is installed on the purging frame. The purging end face of the purging table faces the separation plate.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this utility model. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of this utility model.

[0024] like Figure 1-3 As shown, the double-stage screening and impurity removal equipment for laundry detergent production proposed in this utility model includes an air classifier 11, and the upper and lower parts of the air classifier 11 are respectively equipped with a feed end seat 12 and a discharge end seat 13 for feeding and discharging materials.

[0025] The air separation mechanism includes a separation plate 22 installed in the middle of the air separation table 11. The separation plate 22 includes an inclined part and a horizontal part. A purging frame 23 is provided below the inclined part. A purging table 24 is installed on the purging frame 23. The purging end face of the purging table 24 faces the separation plate 22.

[0026] A vibrating frame 33 is provided below the discharge end seat 13, and the vibrating frame 33 is mounted on the base 31 by a spring member 32;

[0027] The vibration mechanism includes a support 41 installed at the end of the vibration frame 33 and a screen cylinder seat 43 in the middle. A vibration motor 42 that outputs vibration to the screen cylinder seat 43 is installed on the support 41.

[0028] The screening mechanism includes a screen cylinder 51 installed in a screen cylinder seat 43. The middle part of the screen cylinder 51 is divided by a screen mesh 52, and a discharge rack 54 that passes through the screen cylinder 51 is provided below the screen mesh 52.

[0029] It should be noted that: an inclined ramp 21 is provided below one end of the feed end seat 12 that penetrates into the inner cavity of the air classifier 11. The inclined directions of the ramp 21 and the separation plate 22 are opposite, and a conveying gap is left between them. Clumps or clumps of laundry detergent fall from the feed end seat 12 and hit the ramp 21. Under the action of gravity, they accelerate down the inclined surface of the ramp 21 and are concentrated and guided to the outlet of the conveying gap. When the material is thrown out from the end of the ramp 21, it directly hits the surface of the opposite inclined separation plate 22, generating shear force and impact force on the clumps, breaking up the larger, loose clumps, causing the material to splash in different directions, increasing the looseness of the material, and facilitating subsequent air classification.

[0030] In this embodiment, primary screening is performed in the air classifier 11. The laundry detergent material is fed into the feed end seat 12 and enters the area above the separation plate 22. The blowing end face of the blowing table 24 faces the separation plate 22. After the laundry detergent material is dispersed by the slope plate 21 and the separation plate 22, the lightweight impurities such as woven bag fibers and hair are suspended under the action of the airflow of the blowing table 24. The dispersed powder falls through the screen holes on the separation plate 22 under its own gravity and airflow disturbance. Large particles of impurities are always kept away from the screen holes under the blowing action, preventing the separation plate 22 from clogging and preventing the normal powder from falling. Primary screening can achieve smooth powder transmission.

[0031] Secondary screening is carried out through the vibration mechanism and screening mechanism on the vibration frame 33. After the primary air classification screening, most of the light impurities and excessively large lumps in the material have been removed. The high-frequency, low-amplitude vibration force generated by the vibration motor 42 is transmitted to the screen cylinder 51 through the support 41 and the screen cylinder seat 43. The screen 52 is installed in the middle of the screen cylinder 51. The fine powder material is screened in the second stage by vibration to remove unqualified particles and obtain the target product with uniform particle size.

[0032] After two stages of screening, the final product of laundry detergent contains almost no impurities such as fibers or hair, and has a highly uniform particle size, which effectively improves screening efficiency and product quality.

[0033] It is understandable that the separation plate 22 and the screen 52 are provided with screen holes. The mesh size of the screen 52 is larger than that of the separation plate 22. The screen 52 can perform a higher level of screening than the separation plate 22. Through two-stage screening, a target product with uniform particle size can be obtained.

[0034] To provide air for the purging process, the purging table 24 is further connected to the air intake device 25. The air intake end of the air intake device 25 penetrates the outer wall of the air classifier 11. The gas drawn in by the air intake device 25 is purged from below the separation plate 22 by the purging table 24. The purging gas acts on the inclined part of the separation plate 22, and the falling powder falls horizontally.

[0035] In order to output vibration to the vibrating frame 33, vibrating motors 42 are symmetrically arranged at both ends of the vibrating frame 33, and the vibration output directions of the vibrating motors 42 are opposite. Under the synchronous reverse drive of the two vibrating motors 42, the vibration forces they generate are always equal in magnitude and opposite in direction. The two forces are superimposed to form a resultant force, which drives the vibrating frame 33 and the screen cylinder 51 to vibrate strongly in the horizontal direction.

[0036] To facilitate the discharge of fine powder after double-stage screening, the bottom of the screen cylinder 51 is further provided with a discharge boss 53 connected to the vibrating frame 33. The discharge boss 53 is inclined towards the opening of the discharge frame 54. Under the action of vibration, the fine powder moves along the inclined discharge boss 53 towards the opening of the discharge frame 54, which facilitates discharge.

[0037] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within its protection scope. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
