Description

Technical Field

[0001] The utility model relates to the technical field of ceramic processing, in particular to a feeding and screening device with a multi-stage screening structure. Background Art

[0002] The purpose and significance of screening the raw materials used in ceramic pigments is to enable the screening process to mix various raw materials evenly, thereby increasing the density of the organization. Only when the ceramic raw materials reach a certain particle size and particle size composition can they have the necessary molding properties, fluidity, suspension, plasticity, etc. The fine particle size of the raw materials makes it easier to mix raw materials with different components evenly. The finer the raw materials, the higher the surface energy and the greater the chemical reaction activity.

[0003] According to the publicly disclosed ceramic filter plate powder vibration screening device (publication number: CN219965554U), the bottom of the screen drum seat in the above application is also fixedly connected to the base cover through a hollow connecting tube. The base cover is set on a number of compression springs arranged on the top surface of the base. The axis of the compression spring is in the vertical direction. The bottom surface of the base cover is installed with a vibrating body to achieve automatic operation, improve screening efficiency, ensure screening time, and make full use of the powder.

[0004] However, in actual use of the above equipment, the screen drum screens the raw materials through the vibration body and the compression spring, but the screen drum lacks the function of multi-stage screening, which leads to a relatively single fineness greater than the raw material screening, thereby reducing the screening effect; in view of this, we propose a feeding screening device with a multi-stage screening structure. Utility Model Content

[0005] The purpose of the utility model is to provide a feeding and screening device with a multi-stage screening structure to solve the problems raised in the above background technology.

[0008] A socket is formed on the surface of the slider, and the socket facilitates the connection between the fixing plate and the slider. The inner wall of the socket is matched with the outer surface of the plug rod, and the end of the plug rod is fixedly connected to the bottom of the fixing plate;

[0009] A sliding rod, the inner surface of the fixed plate is slidably connected to the outer surface of the sliding rod, a knob is provided on the top of the screen, and the end of the knob is fixedly connected to the end of the threaded rod.

[0010] Preferably, the inner surface of the screen mesh is matched with the inner surface of the screen mesh, and the inner surface of the screen mesh is threadedly connected to the outer surface of the threaded rod.

[0011] Preferably, the outer surface of the sliding block is slidably connected to the inner wall of the sliding groove, and the end of the sliding rod is fixedly connected to the side wall of the screen drum.

[0015] Compared with the prior art, the utility model provides a feeding and screening device with a multi-stage screening structure, which has the following beneficial effects:

[0016] 1. The feeding and screening device with a multi-stage screening structure performs multi-stage screening on the pigment raw materials by providing a screen mesh and a screen drum in cooperation. The cooperation of the plug rod and the plug hole allows the screen drum to be separated or connected to the feeding shell body. The cooperation of the telescopic spring and the slider allows the screen drum to gradually move from the lower end of the feeding shell body to the upper end of the feeding shell body after the feeding shell body completes screening, so as to facilitate taking. The knob cooperates with the threaded rod so that the screen mesh can be adjusted in the position inside the screen drum according to the raw materials, and the screen mesh can be moved out from the inside of the screen drum to discharge the secondary screened materials, thereby improving the effect of multi-stage screening of raw materials and facilitating the distinction of screened raw materials.

[0017] 2. The feeding and screening device with a multi-stage screening structure is provided with a sliding rod so that the feeding shell can move irregularly on the fixed block when it vibrates, causing squeezing force on the fixed spring and the telescopic rod. The repulsive force formed between magnet one and magnet two allows the screen drum to reset inside the feeding shell, so that the screen drum can perform a slight translational movement, thereby improving the screening effect.

A base cover is provided at the bottom of the feeding shell 1, and a vibrating body is provided inside the base cover. A base is provided at the bottom of the base cover. The base and the base cover are connected by a compression spring, so that the feeding shell vibrates. The above-mentioned vibration structure is similar to the base, base cover, vibrating body and compression spring principles mentioned in the Chinese patent (ceramic filter plate powder vibration screening device) with authorization announcement number CN219965554U, and the effect achieved is the same. It is an existing public technical means in this field and will not be elaborated here. The aperture diameter of the screen 3 is larger than the aperture diameter of the screen drum 2, and a discharge port is provided on one side of the feeding shell 1.

[0027] In the utility model, when in use, according to the amount of pigment raw materials, the knob 10 is manually held to rotate the threaded rod 11, thereby allowing the screen 3 to rise and fall inside the screen drum 2. After the raw materials are poured into the screen drum 2, the weight of the raw materials compresses the telescopic spring 5, and the slider 6 slides inside the slide 4, causing the screen drum 1 to gradually sink inside the feeding shell 1. At this time, the excitation body is turned on to vibrate the feeding shell 1. The raw materials first pass through the screening of the screen 3 and then fall into the bottom of the drying trough 2 for secondary screening. The raw materials after the secondary screening are discharged through the discharge port. At the same time, since the magnet 1 13 and the magnet 2 14 are magnets of the same pole, when the screen drum 2 vibrates inside the feeding shell 1, due to the slider 1 2 will slide in the fixed plate 9, and the vibration force makes the slide bar 12 squeeze the telescopic rod 15 and the fixed spring 16, while the repulsive force of the magnet 13 and the magnet 2 14 exerts an opposite force on the slide bar 12, so that the screen drum 2 has a slight parallel displacement inside the feeding shell 1, thereby accelerating the screening of the screen drum 2 larger than the raw material. Finally, when the multi-stage screening is completed, the screen drum 2 is held and an upward force is manually applied to the screen drum 2, so that the insertion rod 8 gradually disengages from the inside of the insertion hole 7, so that the screen drum 2 is separated from the feeding shell 1, and finally the knob 10 is turned. The knob 10 drives the threaded rod 11 to rotate so that the screen 3 gradually moves upward from the inside of the screen drum 2, and finally the raw materials in the screen drum 2 are poured out to distinguish the raw materials for multi-stage screening.

[0028] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
