The weight of the mud and other impurities is greater than the weight of the water body, and they gradually settle below, slowly pushing the water body out of the cleaning pool, which will cause the subsequent ore raw material cleaning effect to become worse and worse, resulting in incomplete cleaning of the ore raw materials, and still leaving a lot of mud and other impurities, affecting the quality of the subsequent prepared calcium carbonate powder, and reducing the use value of the raw material cleaning device.

DETAILED DESCRIPTION

[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0031] The raw material cleaning device for producing calcium carbonate powder disclosed in the present invention is mainly used in conventional double-helix ore washing machines. When cleaning the crushed ore raw materials, impurities such as mud and sand carried by the ore raw materials are accumulated at the lower end of the spiral conveying blades. The weight of the impurities such as mud and sand is greater than the weight of the water body, and they gradually settle below, slowly pushing the water body out of the cleaning pool, which will cause the subsequent ore raw material cleaning effect to become worse and worse, resulting in incomplete cleaning of the ore raw materials, and still leaving a lot of impurities such as mud and sand, affecting the quality of the calcium carbonate powder prepared subsequently.

[0032] Reference Figure 1-Figure 10A raw material cleaning device for producing calcium carbonate powder includes a cleaning tank 1 and two spiral conveying blades 6. The cleaning tank 1 is provided with a flip screening and exporting assembly 9 at the ends of the two spiral conveying blades 6, and the flip screening and exporting assembly 9 includes an exporting frame 901 and two limiting guide rails 903. The two limiting guide rails 903 are fixedly connected to the bottom inner wall of the cleaning tank 1. Two limiting slide bars 918 are slidably connected to the two limiting guide rails 903. The side wall of each limiting slide bar 918 is fixedly connected to a flip cover 913. An extraction cavity and a screening cavity are arranged in the flip cover 913. An extraction hole 912 is opened at the extraction cavity of the flip cover 913. A sieve plate is fixedly connected to the inner wall of the flip cover 913 at the screening cavity. 920, the sieve plate 920 is tilted, a door hole is opened on one side of the flip cover 913 located at the sieve plate 920, the inner wall of the door hole is connected to the blocking door 904 through a hinge, a hydraulic cylinder 915 is fixedly connected near the top of the flip cover 913, the output end of the hydraulic cylinder 915 is fixedly connected to a clamping rod 914, the clamping rod 914 is in contact with the outer wall of the blocking door 904, an extraction pump 911 is fixedly connected to the top of the flip cover 913, the extraction end of the extraction pump 911 is fixedly connected to an extraction pipe 905, one end of the extraction pipe 905 is inserted into the inside of the extraction cavity of the flip cover 913, and the delivery end of the extraction pump 911 is connected to the inside of the screening cavity of the flip cover 913 through a pipeline.

[0033] In a specific application scenario, the extraction pump 2 911 is started, and the impurities such as mud and sand located at the lower layer of the cleaning tank 1 are introduced into the screening chamber through each extraction hole 912. With the introduction of the extracted material, the water falls along the sieve plate 1 920, and then is discharged into the cleaning tank 1 through the drainage hole 919. The mud and sand and other impurities are retained on the sieve plate 1 920. After the hydraulic cylinder 1 907 drives the flip cover 913 to move to the upper layer of the cleaning tank 1, the hydraulic cylinder 2 915 drives the clamping rod 914 to separate from the blocking door 904. Then, impurities such as mud and sand impact the blocking door 904, and are discharged into the upper layer of the cleaning tank 1 through the door hole. The extraction pump 908 is started, and the extraction pump 908 extracts the mixture in the upper layer through the extraction nozzle 922, and then screens this part of the mixture. Impurities such as mud and sand are retained in the sieve plate 2 921 and gradually slide into the drainage bucket 902. The water is discharged into the cleaning tank 1 again through the drain pipe 906, and the mud and sand and other impurities in the cleaning tank 1 are discharged, thereby improving the cleaning effect of the ore raw materials.

[0034] Specifically, when the hydraulic cylinder 907 drives one of the flip covers 913 to rise, the other flip cover 913 will drop accordingly, so that there is always a flip cover 913 in operation inside the cleaning pool 1, thereby preventing the accumulation of impurities such as mud and sand in the lower layer of the cleaning pool 1 from being too thick and causing the subsequent inability to flip to the top for discharge.

[0035] It should be noted that the sieve plate 1 920 and the sieve plate 2 921 placed inside the flip screening and exporting assembly 9 are both in an inclined state to ensure that impurities such as mud and sand above them can slide out. At the same time, the installation of the sieve plate 1 920 and the sieve plate 2 921 reduces the loss of water resources.

[0039] Specifically, before the ore raw material is introduced into the cleaning pool 1, it is placed in the feed frame 801. During its sliding process in the feed frame 801, it impacts each brush tooth 809, causing the oscillation spring rod 812 to be gradually compressed. The resetting of the oscillation spring rod 812 drives the brush teeth 809 to scrape off the mud and sand attached to the ore raw material, thereby completing the preliminary processing of the ore raw material. At the same time, the vibration rod 810 is started, and the vibration plate drives the feed frame 801 to be in an oscillating state, thereby accelerating the discharge of the ore raw material and increasing the probability of the mud and sand attached to the outside of the ore raw material falling off.

[0041] It should be noted that after the ore raw material is cleaned, it is transported to the upper end by the spiral conveyor blade 6 and falls into the unloading frame 201, and then falls onto the stepped unloading plate 204. As the cleaned ore raw material rolls, the water attached to its outside is gradually detached, and the air compressor 206 is started.

With the introduction of the extracted material, the water falls along the sieve plate 1 920, and then is discharged into the cleaning tank 1 through the drainage hole 919. The mud and other impurities are retained on the sieve plate 1 920. After the hydraulic cylinder 1 907 drives the flip cover 913 to move to the upper layer of the cleaning tank 1, the hydraulic cylinder 2 915 drives the clamping rod 914 to separate from the blocking door 904, and the mud and other impurities enter the blocking door 904.
