Abstract
Description
Technical Field
[0001] The utility model relates to a talcum powder preparation device, in particular to a sieving device for talcum powder processing. Background Art
[0002] Talc is a magnesium silicate mineral talc. It is a white or off-white, fine, sand-free powder with excellent physical and chemical properties such as lubricity, anti-stickiness, flow-aiding, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, and strong adsorption. It is widely used in chemical industry, ceramics, cosmetics, medicine, food and other fields. Common talc specifications include 200 mesh, 325 mesh, 500 mesh, 600 mesh, 800 mesh, 1250 mesh to 8000 mesh, etc. In actual production and processing, in order to strictly control the quality of talc, it is necessary to use a screening device to screen the talc.
[0003] For example, application number 2023214032017 discloses a talcum powder screening and classification device, and the above utility model has the following shortcomings: the sieve plate is fixedly installed in the casing, and the screening size of the talcum powder is single. When talcum powder of different specifications needs to be screened, another device is required for processing, which reduces the screening efficiency of the talcum powder and increases the production cost; at the same time, the suction fan directly transports the sucked talcum powder to the collection box through the connecting pipe, which may easily lead to different specifications of the screened talcum powder, affecting the quality of the screened talcum powder, and may affect subsequent use. Utility Model Content
[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desired to provide a sieving device for talcum powder processing.

[0006] A sieving device for talcum powder processing, a feed hopper is inserted in the middle of the top of a chassis, supporting bottom columns are welded on the corners of the bottom of the chassis, temporary storage boxes are mounted on both sides of the chassis, fans are inserted on the two side walls of the top of the chassis, a sieve plate is suspended in the middle lower part of the chassis, a stirring push plate is provided on the upper side of the chassis, a servo motor is installed on the rear outer side of the chassis, a groove is dug on the lower side of the front end of the chassis and a collection box is placed, a maintenance door is embedded on the upper side of the front end of the chassis, a group of buffer plates are installed in the feed hopper, two buffer plates are in a group and are respectively installed on the left and right inner walls of the feed hopper, the extended ends of the buffer plates are tilted downward and gaps are left between adjacent ones, a rotating shaft is installed on the output end of the servo motor and extends into the chassis, There are multiple stirring push plates and they are evenly mounted on the rotating shaft. The stirring push plates are located at the upper end of the sieve plate. Brushes are installed on the extended ends of the stirring push plates. The brushes touch the upper end surface of the sieve plate. The sieve plate is curved and has a number of evenly distributed sieve holes. One end of the sieve plate is attached to the rear inner wall of the chassis. The sieve plate and the chassis are fixedly connected by inserting fastening nuts from the outside. The other end of the sieve plate does not contact the other inner wall of the chassis and is installed with a guide plate. The guide plate is bent and extended downward and is located directly above the second storage area. One side of the maintenance door is rotatably connected to the chassis by a hinge, and the other side of the maintenance door is installed with a card-connected lock together with the chassis. A perspective window is embedded in the middle of the maintenance door.
[0007] Furthermore, one end of the fan extends out of the chassis and is installed with a delivery pipe, the delivery pipe is connected to the temporary storage box, and a discharge pipe with a valve is provided at the bottom end of the temporary storage box.
[0008] Furthermore, one end of the collection box extends into the chassis and is directly below the sieve plate. A partition is provided in the collection box and is divided into a first storage area and a second storage area through the partition. The second storage area is arranged directly below and corresponding to the guide plate, and a handle is welded on the outside of the collection box.
[0009] In summary, the beneficial effects of this application are:
[0010] 1. By setting a sieve plate, one end of the sieve plate is attached to the rear inner wall of the chassis, and the sieve plate and the chassis are fixedly connected together by inserting fastening nuts from the outside, the problem of fixed installation of the sieve plate in the chassis is solved, and the sieve plate can be taken out of the chassis for replacement and maintenance by opening the maintenance door and unscrewing the fastening nuts, and the sieve plate with sieve holes of different specifications can be replaced, and the required sieve plate can be installed in the chassis through matching fastening nuts, so that talcum powder of different specifications can be screened, the screening efficiency of talcum powder can be improved, and the production cost can be reduced. The stirring push plate is driven by a servo motor and a rotating shaft, and the talcum powder with larger particles on the sieve plate can be pushed to the second storage area for collection and collection. At the same time, the brush on the stirring push plate cleans the sieve holes, and the speed of talcum powder passing through the sieve holes is increased, which greatly improves the work efficiency. The setting of the maintenance door is convenient for users to inspect and replace the sieve plate and other components inside the chassis, thereby enhancing the service life of the entire device and improving practicality.
[0011] 2. By setting up a fan, the fan collects the talcum powder floating in the chassis, and then sends it to the temporary storage box through a conveying pipe for separate storage.
