Description

Technical Field

[0001] This utility model relates to the field of calcium hydroxide production and processing technology, specifically to a powder selection device for producing calcium hydroxide. Background Technology

[0002] Calcium hydroxide is an inorganic compound with the chemical formula Ca(OH)₂, commonly known as slaked lime or quicklime. When calcium hydroxide is added to water, it separates into two layers: the upper aqueous solution is called clear limewater, and the lower suspension is called milk of lime or lime slurry. The clear limewater can be used to test for carbon dioxide, while the turbid milk of lime is a building material. Calcium hydroxide is a strong alkali with bactericidal and antiseptic properties, but it is corrosive to skin and fabrics. Calcium hydroxide is used in the manufacture of bleaching powder, water softeners, disinfectants and insecticides, depilatory agents for leather tanning, sugar refining, and building materials, among other applications.

[0003] A search revealed that Chinese Patent Publication No. CN220697456U discloses a powder classifier for producing calcium hydroxide, belonging to the field of calcium hydroxide production technology. This invention addresses the problems of insufficient performance and low efficiency of existing powder classifiers. The device includes a processing frame with a processing tank inside. A vibrating motor is fixed to the lower center of the frame, and connecting rods are fixed to the four corners of the lower end. A stabilizing plate is fixed to the lower end of each of the four connecting rods, and support legs are slidably connected to the outer surfaces of the four stabilizing plates. Each support leg has a circular groove in its center and a spring is fixed to its upper end. A screening frame with several screening holes is fixed to the center of the processing tank. This invention uses a vibrating motor to drive the processing frame for vibration, achieving accurate screening and improving the performance of the powder classifier. The size of the discharge port can be adjusted by manually turning a handwheel, further improving the efficiency of the powder classifier.

[0004] However, this device also has the following drawbacks:

[0005] There is no screening structure between the screening rack and the collection box of this device. Unscreened calcium hydroxide may enter the collection box from the top of the screening rack. In particular, when too much calcium hydroxide is added, it will seriously affect the powder selection effect of the device. This device does not solve this problem. Utility Model Content

[0006] The purpose of this invention is to provide a powder classifier for producing calcium hydroxide. By setting up multiple sets of sieve plates in conjunction with the inner cylinder, calcium hydroxide can be screened. Calcium hydroxide must pass through the sieve plates before entering the outer cylinder, which improves the screening effect. Even if a large amount of calcium hydroxide is added to the inner cylinder, only those smaller than the sieve plate aperture can enter the outer cylinder, ensuring the powder classification effect and solving the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] A powder classifier for producing calcium hydroxide includes an outer cylinder and an inner cylinder, wherein the outer cylinder and the inner cylinder are sealed and rotatably coupled, and the outer cylinder is fixedly connected to a support frame.

[0009] It also includes a screening component, which includes multiple sets of sieve plates and spiral flaps. The inner cylinder has multiple sets of mounting grooves on a portion of its surface inside the outer cylinder. The sieve plates are fixedly installed in the mounting grooves, and the spiral flaps are fixedly installed on the inner wall of the inner cylinder.

[0010] It also includes a rotating assembly, which includes a rotating motor. The output of the rotating motor is fixedly mounted with a drive gear, which meshes with a gear ring, which is fixedly mounted on the surface of the inner cylinder.

[0011] Preferably, a discharge port is fixedly installed at the bottom of the outer cylinder, and a sealing cap is threaded onto the bottom of the discharge port.

[0012] Preferably, a portion of the inner cylinder is disposed inside the outer cylinder, and another portion of the inner cylinder is disposed outside the outer cylinder.

[0013] Preferably, the inner cylinder is rotatably connected to the inner wall of the outer cylinder on one side inside the outer cylinder, and a conveying pipe is fixedly installed on one side outside the outer cylinder of the inner cylinder.

[0014] Preferably, the conveying pipe is rotatably connected to the rotating pipe, and one side of the rotating pipe is rotatably connected to the support frame.

[0015] Preferably, the rotating motor is fixedly mounted on the mounting bracket, and the mounting bracket is fixedly mounted on one side of the outer cylinder.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] This utility model features multiple sets of sieve plates used in conjunction with an inner cylinder. It has a simple structure, is convenient and practical, and can screen calcium hydroxide. Even if a large amount of calcium hydroxide is added to the inner cylinder, only calcium hydroxide smaller than the sieve plate aperture can enter the outer cylinder, ensuring the powder selection effect. By setting a rotating component, the inner cylinder can be rotated, and when used with a spiral flap, the calcium hydroxide can be turned over, greatly improving the screening efficiency.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1 to 3 This utility model provides a technical solution:

[0024] A powder classifier for producing calcium hydroxide includes an outer cylinder 1 and an inner cylinder 2. The outer cylinder 1 and the inner cylinder 2 are sealed and rotatably fitted together. A portion of the inner cylinder 2 is disposed inside the outer cylinder 1. One side of the inner cylinder 2 inside the outer cylinder 1 is rotatably connected to the inner wall of the outer cylinder 1. The other part of the inner cylinder 2 is disposed outside the outer cylinder 1. A conveying pipe 11 is fixedly installed on one side of the inner cylinder 2 outside the outer cylinder 1. The conveying pipe 11 is rotatably connected to a rotating pipe 12. One side of the rotating pipe 12 is rotatably connected to a support frame 3. A discharge port 9 is fixedly installed at the bottom of the outer cylinder 1. A sealing cap 10 is threadedly installed at the bottom of the discharge port 9. The outer cylinder 1 is fixedly connected to the support frame 3.

[0025] By using the outer cylinder 1 and the inner cylinder 2 together, the screened calcium hydroxide can be stored separately to prevent cross-contamination. This also improves the sealing of the device, reduces the amount of dust generated during screening that is dispersed into the air, and protects the environment of the processing site. Furthermore, by using the rotating pipe 12 in conjunction with the conveying pipe 11, rotating the rotating pipe 12 to make its opening face up or down makes it easy for operators to add or remove materials into the inner cylinder 2.

[0026] It also includes a screening component, which includes multiple sets of sieve plates 4 and spiral flaps 5. Multiple sets of mounting grooves are opened on part of the inner cylinder 2 inside the outer cylinder 1. The sieve plates 4 are fixedly installed in the mounting grooves, and the spiral flaps 5 are fixedly installed on the inner wall of the inner cylinder 2.

[0027] By setting up multiple sets of sieve plates 4 to work with the inner cylinder 2, calcium hydroxide can be screened. Even if a large amount of calcium hydroxide is added to the inner cylinder 2, only those smaller than the aperture of the sieve plate 4 can enter the outer cylinder 1, ensuring the powder selection effect.

[0028] It also includes a rotating assembly, which includes a rotating motor 6. The output of the rotating motor 6 is fixedly mounted with a drive gear 7. The drive gear 7 meshes with a gear ring 8. The gear ring 8 is fixedly mounted on the surface of the inner cylinder 2. The rotating motor 6 is fixedly mounted on a mounting bracket 13. The mounting bracket 13 is fixedly mounted on one side of the outer cylinder 1.

[0029] By setting a rotating motor 6, the output end of the rotating motor 6 can drive the drive gear 7 to rotate. The drive gear 7 drives the inner cylinder 2 to rotate through the gear ring 8, which facilitates the turning and screening of calcium hydroxide into the inner cylinder 2, and also facilitates the turning of calcium hydroxide outward for discharge, making it convenient for operators to use flexibly.

[0030] In practical use, move the device to the designated position, ensuring the opening of the rotating tube 12 faces upwards. Add calcium hydroxide into the rotating tube 12 through its opening. The calcium hydroxide, under its own gravity, enters the inner cylinder 2 through the conveying pipe 11. Start the rotating motor 6, controlling its output to drive the drive gear 7 to rotate forward. The drive gear 7, through the gear ring 8, drives the inner cylinder 2 to rotate. The spiral flap 5 inside the inner cylinder 2 continuously flips the calcium hydroxide towards the inside of the inner cylinder 2, causing the calcium hydroxide to continuously pass over the surface of the sieve plate 4. Since the diameter of the calcium hydroxide is smaller than that of the sieve plate... Calcium hydroxide with a 4-hole diameter enters the outer cylinder 1 through the sieve plate 4. Calcium hydroxide with a diameter larger than the sieve plate 4 cannot pass through the sieve plate 4 and remains inside the inner cylinder 2. After screening, the output end of the control motor 6 drives the inner cylinder 2 to rotate in the opposite direction, thereby causing the spiral flap 5 to push the calcium hydroxide in the inner cylinder 2 to move to the outside of the inner cylinder 2 and move to the rotating pipe 12 through the conveying pipe 11. By rotating the opening of the rotating pipe 12 downward, the calcium hydroxide inside the inner cylinder 2 can be discharged. Then, the sealing cover 10 is opened, and the calcium hydroxide inside the outer cylinder 1 is discharged through the discharge port 9.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
