Description

Technical Field

[0001] This utility model relates to the field of screening device technology, and in particular to a screening device for raw material particles in ceramic jars. Background Technology

[0002] In the process of making pottery jars, the uniformity of the size of the raw material particles directly affects the molding quality and structural stability of the pottery jars, so it is necessary to strictly screen the raw material particles.

[0003] Traditional screening devices often have many limitations, such as inconvenient filter replacement, difficulty in adapting to the screening needs of raw materials of different coarseness, resulting in low operating efficiency; at the same time, there is often agglomeration in the raw materials, which can easily clog the equipment during feeding, and uneven feeding can greatly reduce the screening effect, failing to meet the requirements of raw material particle precision for ceramic jar production.

[0004] Therefore, those skilled in the art have provided a ceramic pot raw material particle screening device to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a ceramic pot raw material particle screening device. The assembly mechanism can quickly install and remove filter screens of different specifications through the locking rod and locking hole, which can be used to fix the filter screens of different specifications, adapt to various screening needs, and is convenient to install and remove, reducing material leakage. The feeding mechanism uses a T-shaped dispersing rod to disperse lumpy raw materials and a spiral conveyor wheel to feed the material evenly, avoiding feeding blockage and improving screening efficiency and quality. The two work together to improve the screening performance and applicability of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A ceramic pot raw material particle screening device includes a screening box, a connecting plate and multiple fixed frames. Side plates are fixedly connected to both sides of the front end face of the connecting plate. The fixed frames are arranged between the two side plates. A filter screen is fixedly sleeved inside the lower part of the fixed frame. An assembly mechanism is provided between the fixed frame and the side plates. A feeding mechanism is fixedly sleeved on the upper end face of the screening box.

[0008] The assembly mechanism includes multiple fixing slots, which are respectively opened on the front and rear sides of the outer wall of the fixing frame. A return spring is fixedly connected to the inner wall of one side of the fixing slot, and a movable seat is fixedly connected to the other end of the return spring. A locking rod is fixedly connected to the other side of the movable seat. Locking holes are opened on the front and rear sides of the outer wall of one side of the side plate, and the locking rod is locked in the locking hole.

[0009] The above technical solution involves moving the movable seat to compress the return spring, causing the locking rod to retract into the fixing groove. After the fixing frame is placed between the two side plates, the return spring rebounds and pushes the movable seat, causing the locking rod to pop out and lock into the locking hole of the side plate, thus completing the installation of the fixing frame.

[0010] Furthermore, the feeding mechanism includes a feeding frame, a main stirring rod is rotatably connected to the center of the upper inner wall of the feeding frame, auxiliary stirring rods are rotatably connected to both sides of the upper inner wall of the feeding frame, multiple T-shaped dispersing rods are fixedly connected to the outer walls of both sides of the main stirring rod and the auxiliary stirring rods, a second drive motor is fixedly connected to the upper end face of the feeding frame, the output end of the second drive motor passes through the feeding frame and is fixedly connected to the main stirring rod, and a feeding cylinder is fixedly connected to one side of the feeding frame;

[0011] Through the above technical solution, the material can be put into the injection frame through the injection cylinder. The No. 2 drive motor drives the main stirring rod and the auxiliary stirring rod to rotate synchronously. The T-shaped dispersing rods on the main stirring rod and the auxiliary stirring rod stir and disperse the raw materials.

[0012] Furthermore, a drive gear is fixedly sleeved on the outer wall of the main stirring rod, and a driven gear is fixedly sleeved on the outer wall of each of the two auxiliary stirring rods. The drive gear and the driven gear are meshed together. A protective frame is fixedly connected to the upper inner wall of the injection frame, and both the drive gear and the driven gear are movably arranged within the protective frame.

[0013] The above technical solution, through the setting of driving gear and driven gear, can achieve a better rotation effect on the two stirring rods.

[0014] Furthermore, the lower ends of the two auxiliary stirring rods are fixedly connected to a spiral conveying wheel, a guide cone is fixedly connected to the middle of the lower inner wall of the injection frame, and a discharge port is opened at the front and rear of the lower end face of the injection frame, with the spiral conveying wheel movably disposed in the discharge port;

[0015] The above technical solution guides the material downwards to the discharge port through the set guide cone, and assists the rotation of the spiral conveyor wheel at the lower end of the stirring rod to evenly transport the raw material to the filter screen in the screening box for subsequent screening operations.

[0016] Furthermore, a toggle lever is fixedly connected to the lower end face of the movable seat, and a toggle groove is provided on the lower inner wall of the fixed groove, with the toggle lever movably disposed in the toggle groove;

[0017] The above technical solution allows for the limitation of the movable seat's movement by using a set lever.

[0018] Furthermore, buffer grooves are provided on the upper and lower sides of the inner walls of both sides of the screening box. A fixed rod is fixedly connected between the upper and lower inner walls of the buffer grooves. Buffer springs are movably sleeved on the upper and lower sides of the outer walls of the fixed rods. A movable sleeve is movably sleeved at the middle of the outer wall of the fixed rods. The movable sleeve is fixedly connected to the side plate. A rotating shaft is rotatably connected between the inner walls of both sides of the screening box. Cams are fixedly sleeved on both sides of the outer wall of the rotating shaft. Extrusion strips are fixedly connected to the upper surfaces of the two side plates. The cams and extrusion strips are pressed together. A No. 1 drive motor is fixedly connected to one outer wall of the screening box. The output end of the No. 1 drive motor is fixedly connected to the rotating shaft.

[0019] The above technical solution uses a drive motor to rotate a shaft, causing a cam to rotate. The cam squeezes the extrusion bar, pushing the side plate upward. The moving sleeve compresses the upper buffer spring along the fixed rod. After the cam rotates away, the lower buffer spring rebounds, causing the side plate to move downward, thus forming a vibrating screen.

[0020] Furthermore, a door is hinged on one side of the front end face of the screening box, and a handle is fixedly connected to the middle of one side of the front end face of the door.

[0021] The above technical solution, with its user door and handle, allows for convenient maintenance of the device.

[0022] Furthermore, support columns are fixedly connected to the lower end face of the screening box near the four corners, and anti-slip pads are fixedly connected to the lower ends of the multiple support columns.

[0023] The above technical solution, through the installation of support columns and anti-slip pads, can achieve the purpose of stable support for the device.

[0024] This utility model has the following beneficial effects:

[0025] 1. The ceramic pot raw material particle screening device proposed in this utility model has an added assembly mechanism that enables quick assembly and disassembly of the fixed frame and side plate. It facilitates the replacement of filter screens of different specifications according to the size of the raw material particles, improving the adaptability of the device to various screening needs. Specifically, the engagement of the locking rod and the locking hole ensures that the fixed frame is stable and does not shake during the screening process, avoiding the filter screen misalignment caused by vibration, which affects the screening accuracy. The setting of the toggle rod makes the assembly and disassembly operation more convenient and saves the time of replacing the filter screen. At the same time, the return spring provides continuous clamping force to ensure a tight connection between the fixed frame and the side plate, reducing the problem of material leakage during the screening process.

[0026] 2. The ceramic pot raw material particle screening device proposed in this utility model has an added feeding mechanism that can break up the clumps of ceramic pot raw materials, making the raw material particles uniform, avoiding large pieces of raw material from clogging the feed inlet, and ensuring smooth screening. Specifically, the stirring action of the T-shaped dispersing rod can disperse the clumps of raw materials into fine particles, improving screening efficiency. The spiral conveyor wheel can evenly transport the raw materials to the screening area, preventing raw material accumulation from affecting the screening effect. At the same time, the guide cone guides the flow of raw materials, ensuring uniform distribution of raw materials, making full use of all parts of the filter screen, and improving screening quality.

[0027] 3. The ceramic pot raw material particle screening device proposed in this utility model has an assembly mechanism that can quickly install and remove filter screens of different specifications through locking rods and locking holes, adapting to various screening needs. It is also convenient to install and remove, reducing material leakage.
