Description

Technical Field

[0001] This utility model relates to the field of ceramic glaze production technology, specifically to a crushing and screening device for ceramic glaze production. Background Technology

[0002] Ceramic glaze is a mixed mineral material applied to the surface of a ceramic body and fired at high temperature to form a glassy thin layer. Its main components include quartz, feldspar, clay, and metal oxides. Ceramic glaze is an important component in ceramic production. Its function is to provide physical protection for ceramic products, preventing moisture from penetrating into the ceramic, and it can also serve a decorative purpose. During the production process, ceramic glaze needs to be crushed and the crushed raw materials screened.

[0003] However, in the existing ceramic glaze crushing and screening process, the inherent stickiness of the ceramic glaze causes the screening screens to easily become clogged, resulting in reduced operating efficiency of the crushing and screening equipment. Therefore, it does not meet the current needs. To address this, we propose a crushing and screening device for ceramic glaze production. Utility Model Content

[0004] The purpose of this utility model is to provide a crushing and screening device for ceramic glaze production, so as to solve the problems mentioned in the background art, such as the inherent stickiness of ceramic glaze, which makes the screening screen easy to get clogged, thus reducing the operating efficiency of the crushing and screening equipment.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a crushing and screening device for ceramic glaze production, comprising a crushing and screening machine, wherein the crushing and screening machine is provided with a crushing and screening chamber inside, and two relatively rotating crushing rollers are installed on the inner side of the crushing and screening chamber. A screen fixing block is provided below the two crushing rollers, and a screen is fixed on the outer side of the bottom end of the screen fixing block. A rotating ring is rotatably installed on the bottom of the screen fixing block, and one end of the rotating ring extends through a rotating rod into the interior of the screen fixing block, and the rotating rod is rotatably connected to the rotating ring. Multiple sets of unblocking components are fixed on the outer surface of the rotating rod, and each set of unblocking components consists of three components arranged in a circular array around the axis of the rotating rod.

[0006] Preferably, the fixing frame includes a vertical rod and two fixing rods, the two fixing rods being symmetrical to the vertical rod, and one end of the fixing rods being fixed to the inner wall of the crushing and screening chamber.

[0007] Preferably, a dredging motor is fixed inside the screen fixing block, a drive gear is fixed at the output shaft end of the dredging motor, and a rotating gear ring is meshed on the outer side of the drive gear.

[0008] Preferably, the rotating gear ring is fixed inside the rotating ring and located below the rotating rod, and a contact gear is fixed at the end of the rotating rod that extends into the screen fixing block.

[0009] Preferably, a fixed gear ring is meshed above the contact gear, and the fixed gear ring is fixedly connected to the screen fixing block.

[0010] Preferably, the bottom of the screen fixing block is provided with a vent hole to ensure that the heat generated during motor operation is dissipated.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention utilizes a motor-driven drive gear to rotate a rotating gear ring and a rotating ring. This rotating ring causes a rotating rod and a contact gear to rotate around the axis of the screen fixing block. When the contact gear moves against the bottom of the fixing gear ring, it causes the rotating rod and the unblocking rod to rotate around the axis of the rotating rod. This unblocking rod, which rotates, clears the blocked screen holes inside the screen, thus ensuring that the operating efficiency of the equipment does not decrease. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figures 1 to 4As shown, a crushing and screening device for ceramic glaze production includes a crushing and screening machine 1. The crushing and screening machine 1 has a crushing and screening chamber 2 inside. Two crushing rollers 3 are installed on the inner side of the crushing and screening chamber 2, which rotate in opposite directions. A screen fixing block 5 is provided below the two crushing rollers 3. A screen 6 is fixed on the outer side of the bottom end of the screen fixing block 5. A rotating ring 7 is rotatably installed on the bottom of the screen fixing block 5. One end of the rotating ring 7 extends through a rotating rod 8 into the interior of the screen fixing block 5. The rotating rod 8 is rotatably connected to the rotating ring 7. Multiple sets of unblocking components are fixed on the outer surface of the rotating rod 8. Each set of unblocking components has three components arranged in a circular array around the axis of the rotating rod 8. The rotating rod 8 drives the rotating ring 7 to rotate around the axis of the screen fixing block 5, thereby causing the rotating rod 8 to drive the unblocking rod 13 to rotate. The unblocking rod 13 in the rotation unblocks the screen holes inside the screen 6.

[0020] The fixing frame 4 includes a vertical rod and two fixing rods. The two fixing rods are symmetrical to the vertical rod, and one end of the fixing rod is fixed to the inner wall of the crushing and screening chamber 2. The fixing frame 4 fixes the screen fixing block 5 and the screen 6, thereby preventing the screen 6 from falling downward.

[0021] A cleaning motor 14 is fixed inside the screen fixing block 5. A drive gear 12 is fixed to the output shaft end of the cleaning motor 14. A rotating gear ring 11 is meshed on the outer side of the drive gear 12. The rotating gear ring 11 is fixed inside the rotating ring 7 and located below the rotating rod 8. A contact gear 9 is fixed to the end of the rotating rod 8 that extends into the screen fixing block 5. A fixed gear ring 10 is meshed on the upper part of the contact gear 9. The fixed gear ring 10 is fixedly connected to the screen fixing block 5. This ensures that when the cleaning motor 14, drive gear 12, and rotating gear ring 11 drive the rotating ring 7 to rotate, the contact gear 9 rolls against the bottom of the fixed gear ring 10, thereby allowing the rotating ring 7 and the cleaning rod 13 to rotate freely.

[0022] The bottom of the screen fixing block 5 is provided with ventilation holes to ensure that the heat of the unblocking motor 14 is dissipated, thereby preventing the unblocking motor 14 from malfunctioning or being damaged due to untimely heat dissipation.

[0023] Working principle: First, the power supply to the device is turned on. After the power is turned on, the two crushing rollers 3 rotate relative to each other. Then, the operator adds the ceramic glaze to be crushed and screened into the crushing and screening chamber 2 from the top. After entering the crushing and screening chamber 2, the ceramic glaze is crushed by the two crushing rollers 3. The crushed ceramic glaze falls onto the surface of the screen 6. Ceramic glaze with a diameter smaller than the diameter of the screen holes of the screen 6 passes through the inside of the screen 6. During the long-term crushing and screening process, some ceramic glaze will adhere to the inside of the screen 6 due to its stickiness, affecting the screen. When the screen holes of screen 6 become clogged, the power supply to the unblocking motor 14 is turned on and started. The unblocking motor 14 drives the rotating ring 7 to rotate through the drive gear 12 and the rotating gear ring 11. This causes the rotating ring 7 to drive the rotating rod 8 and the contact gear 9 to rotate around the axis of the screen fixing block 5. When the contact gear 9 moves against the bottom of the fixing gear ring 10, it causes the rotating rod 8 and the unblocking rod 13 to rotate around the axis of the rotating rod 8. In this way, the unblocking rod 13 in the rotation can be used to unblock the screen holes inside the screen 6, thereby ensuring that the operating efficiency of the equipment does not decrease.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
