Description

TECHNICAL FIELD

[0001] The utility model belongs to the production technology field of zinc stearate, especially a filter device for zinc stearate production. BACKGROUND

[0002] Zinc stearate is a white powder and insoluble in water. Zinc stearate is mainly used as a lubricant and a release agent for styrene resin, phenolic resin and amine-based resin. It also has the functions of vulcanizing activator and softening agent in rubber. Zinc stearate can be used as a heat stabilizer, a lubricant, a grease, a promoter, a thickening agent, etc. For example, it can be used as a heat stabilizer for PVC resin. It is used for general industrial transparent products. When used with calcium soap, it can be used for non-toxic products. Generally, the product is mainly used for soft products, but in recent years, it has begun to be used for hard transparent products such as mineral water bottles, water pipes and other products. The product has good lubricity and can improve the scaling and precipitation phenomenon. It can also be used as a lubricant, a release agent, a flatting agent for paint and an additive for paint.

[0003] CN201821555646.6 discloses a zinc stearate production filtering device, which comprises a brine tank and a reaction kettle. The brine tank and the reaction kettle are fixedly connected through a conveying pipeline.

[0036] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0037] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0038] like Figures 1-6 As shown, a filtration device for zinc stearate production includes an upper shell 1, a lower shell 2, a filter cylinder 3, a feed pipe 4, an anti-clogging mechanism, and a connecting mechanism. The lower shell 2 is detachably connected to the bottom of the upper shell, and a discharge hole 21 is provided at its bottom. The filter cylinder 3 has an opening at the top, and filter holes 31 are evenly provided on its side walls and bottom. It is detachably connected to the inner wall of the lower shell through the connecting mechanism. The feed pipe 4 is fixed to the upper shell, and one end of it extends into the filter cylinder.

[0039] Specifically, the anti-clogging mechanism includes a rotating shaft 51, a connecting rod 52, a guide post 53, a first elastic element 54, a fixing plate 55, bristles 56, and a driving element 57. One end of the rotating shaft 51 is rotatably connected to the upper housing, and its axis coincides with the axis of the filter cartridge. The connecting rod 52 is evenly fixed on the rotating shaft and has multiple circular holes. The guide posts 53 are respectively inserted into the circular holes and can slide relative to the circular holes. The fixing plate 55 is fixed to the end of the guide post. The first elastic element 54 is a spring, which is sleeved on the guide post, and one end of it is fixed to the fixing plate. The upper end is fixed to the connecting rod; the bristles 56 are detachably connected to the fixed plate and are in contact with the inner wall of the filter cylinder; the drive component 57 is a servo motor, whose output shaft is connected to the rotating shaft. When the drive component is started, the rotating shaft is rotated, which can drive the bristles to slide on the inner wall of the filter cylinder, thereby brushing out the impurities on the inner wall of the filter cylinder and in the filter holes, thus preventing the filter holes from being blocked. Furthermore, by pushing the bristles through the first elastic element, it can be ensured that the bristles can enter the filter holes for unblocking, and the bristles can also be worn to a certain extent to ensure the cleaning effect.

[0040] As a preferred embodiment, the anti-clogging mechanism also includes a mounting plate 581, a flexible insert plate 582, and a locking block 583. The mounting plate 582 is used to fix the brush bristles. The flexible insert plate 582 is fixed on the mounting plate, and the fixing plate 55 is provided with a insertion groove 551 that mates with the flexible insert plate. The locking block 583 is fixed on the flexible insert plate and has an inclined surface. When installing the brush bristles, the flexible insert plate is aligned with the insertion groove and inserted. The locking block will squeeze the flexible insert plate to deform. When the locking block has completely passed through the insertion groove, the flexible insert plate will return to its original shape, so that the locking block abuts against the side wall of the fixing plate, thereby completing the fixation. When it is necessary to replace the brush bristles, the mounting plate can be removed by pressing the locking block to make it pass through the insertion groove, which is very convenient for replacement.

[0041] Specifically, the connecting mechanism includes a support rod 61, a sleeve 62, a support plate 63, and a locking assembly. One end of the support rod 61 is fixed to the inner wall of the lower housing; the sleeve 62 is fixed to the end of the support rod, and the sleeve allows the filter cartridge to be inserted; the support plate 63 is fixed to the bottom of the sleeve to support the filter cartridge; the locking assembly includes a mounting hole 64, a second elastic element 65, a push rod 66, and a ball bearing 67. The mounting hole 64 is formed on the inner wall of the sleeve; the second elastic element 65 is a spring, one end of which is fixed in the mounting hole; the push rod 66 is fixed to the end of the second elastic element and can slide relative to the inner wall of the mounting hole; the ball bearing 67 is rotatably connected to the end of the push rod; the filter cartridge 3 is provided with a locking hole 32 that cooperates with the push rod, and the end of the locking hole is provided with a guide groove 33. The guide grooves located on the upper and lower sides of the locking hole allow the ball bearings to slide. The bottom of the filter cylinder has rounded corners. When installing the filter cylinder, align it with the sleeve and move the filter cylinder downwards. The rounded corners at the bottom of the filter cylinder will squeeze the ball bearings, pressing the top rod and the ball bearings into the mounting hole. When the bottom of the filter cylinder is in contact with the support plate, rotate the filter cylinder. When the top rod is aligned with the locking hole, the second elastic element will push the top rod into the locking hole, thus fixing the filter cylinder and preventing it from rotating during brush cleaning. When it is necessary to clean the impurities inside the filter cylinder, move the upper shell upwards to remove the anti-clogging mechanism from the filter cylinder. Then pull the filter cylinder upwards. The guide grooves will squeeze the ball bearings, pressing them into the mounting hole, allowing the filter cylinder to be removed from the sleeve. Disassembly is very convenient.

[0042] In other embodiments, the connecting rod 52 is an "L"-shaped rod, which can clean both the side wall and the bottom wall of the filter cartridge.

[0043] In other embodiments, a sieve plate 22 is inclined on the inner wall of the lower housing 2, and the sieve plate is provided with sieve holes, and the inclination angle of the sieve plate is thirty degrees.

[0044] In other embodiments, both the upper and lower housings are provided with flanges 7, and the flanges are provided with screws 71, which allow for quick assembly and disassembly of the upper and lower housings.

[0045] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the invention involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
