Description

Technical Field

[0001] This utility model relates to the field of screening machine technology, and in particular to a vibrating screening machine for producing molten ceramic sand. Background Technology

[0002] Ceramic sand is made by a high-temperature phase-fixing method at over 2000 degrees Celsius. It is particularly suitable for shot peening strengthening in the production and maintenance of metal parts, as well as shot peening forming of light alloy parts. The surface treatment is smooth and uniform with high consistency, enabling the treated workpiece to obtain good surface quality. The screening machine drives the screen to slide back and forth, causing the ceramic sand to slide back and forth above the screen plate, and allowing ceramic sand smaller than the screen holes to pass through the screen holes for screening.

[0003] While existing screening machines can achieve screening through the reciprocating sliding of the screen, large particles of ceramic sand will continuously accumulate on the screen plate after long-term operation. These accumulated large particles will occupy the effective screening area of ​​the screen plate, making it difficult for small particles of ceramic sand to pass through the screen holes, directly reducing screening efficiency. On the other hand, the accumulated large particles may form a "barrier layer" during the reciprocating motion of the screen plate, interfering with the normal screening path of small particles. When the accumulation reaches a certain level, the machine needs to be stopped for cleaning. If it is manually shoveled out with tools, not only is the operating space limited and the labor intensity high, but the cleaning is also not thorough, and the remaining large particles will still affect subsequent screening. If the entire screen frame is disassembled and emptied, the process is cumbersome and the disassembly and assembly are time-consuming, which seriously reduces the screening efficiency of ceramic sand. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the high labor intensity and the impact of prolonged downtime on screening efficiency when collecting large-particle ceramic sand on sieve plates.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A vibrating screen for producing molten ceramic sand includes a base plate. A rapid discharge mechanism is provided above the base plate. The rapid discharge mechanism includes two vertical plates. The lower ends of the two vertical plates are symmetrically distributed and fixedly connected to the upper end of the base plate. The opposing surfaces of the two vertical plates are fixedly connected to symmetrically distributed sliding rods. The sliding rods are slidably sleeved with movable sleeves. Screening frames are fixedly connected to the opposing surfaces of the two movable sleeves. The front of the screening frame is provided with a slot. A reciprocating moving mechanism is provided on one side of the screening frame.

[0007] Preferably, a sieve plate is movably inserted into the inner wall of the slot, a handle is fixedly connected to the front of the sieve plate, and a fixing rod is fixedly connected to the front of the screening frame.

[0008] Preferably, a stop block is rotatably connected to the outside of the fixed rod via a damping bearing, the back of the stop block is in contact with the front of the screen plate, a limit plate is fixedly connected to the lower end of the screen plate, and the back of the limit plate is in contact with the rear inner wall of the screening frame.

[0009] Preferably, a guide plate is fixedly connected to the lower end of the limiting plate, a collection box is provided at the upper end of the bottom plate, and a partition is fixedly sleeved on the inner wall of the collection box.

[0010] Preferably, the reciprocating moving mechanism includes a connecting rod, one end of which is fixedly connected to one side of the screening frame, and the other end of which passes through to one side of one of the vertical plates and is fixedly connected to a moving block.

[0011] Preferably, the upper end of the moving block is provided with a strip-shaped drive through groove, and a support plate is fixedly connected to one side of one of the upright plates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In this invention, the screening frame is supported by a vertical plate, a sliding rod, and a movable sleeve in the rapid discharge mechanism. The screen plate, through slots, blocks, and limiting plates, works in conjunction with a guide plate and a collection box with partitions to quickly collect large particles of ceramic sand.

[0024] Example

[0025] like Figures 1-4As shown, this utility model provides a technical solution: a vibrating screening machine for producing molten ceramic sand, including a base plate 1, on which a rapid discharge mechanism and a reciprocating movement mechanism are provided to achieve efficient screening, rapid slag removal and classified collection.

[0026] The two vertical plates 2 provide a stable support frame for the entire screening machine. Their lower ends are symmetrically connected to the upper end of the base plate 1, ensuring the stability of the screening machine during operation. The symmetrically distributed sliding rods 21 are connected to the opposite surfaces of the vertical plates 2, providing a sliding track for the moving sleeve 22.

[0027] The movable sleeve 22 is slidably connected to the outside of the slide rod 21, which can drive the screening frame 23 to reciprocate in the direction of the slide rod 21. This structural design ensures the smoothness and stability of the movement of the screening frame 23, providing the basic conditions for the screening of ceramic sand.

[0028] The screening frame 23 is used to hold ceramic sand raw materials. The slot 24 on its front provides a convenient channel for cleaning the screen plate 25. The screen plate 25 is movably inserted into the inner wall of the slot 24. This movable connection method makes it easy to clean when there is a lot of large ceramic sand particles on the screen plate 25. The handle 26 fixedly connected to the front of the screen plate 25 makes it easy for the operator to pull the screen plate 25, improving the convenience of operation.

[0029] The fixing rod 27 is fixedly connected to the front of the screening frame 23. The outside of the rod is rotatably connected to the stop block 28 through the damping bearing. After the screen plate 25 is installed, the stop block 28 can be rotated so that its back side contacts the front side of the screen plate 25, thereby limiting the screen plate 25 and preventing the screen plate 25 from coming out of the slot 24 during the screening process, thus ensuring the stability of the screening process.

[0030] The limiting plate 29 is fixedly connected to the lower end of the sieve plate 25. Its back side contacts the rear inner wall of the screening frame 23, which further limits the installation position of the sieve plate 25, ensuring that the sieve plate 25 is accurately positioned within the screening frame 23, which is beneficial to improving the screening effect.

[0031] The guide plate 210, which is fixedly connected to the lower end of the limiting plate 29, can guide small ceramic sand particles passing through the screen plate 25 into the collection box 211. At the same time, it can also guide large ceramic sand particles to slide into the designated area of ​​the collection box 211 when cleaning large ceramic sand particles.

[0032] The collection box 211 set at the upper end of the base plate 1 is used to collect the sieved ceramic sand. The partition 212 fixedly sleeved on its inner wall divides the collection box 211 into two areas, which are used to collect ceramic sand of different sizes respectively. This realizes the classified collection of ceramic sand, which is convenient for subsequent processing and use and improves production efficiency.

[0033] One end of the connecting rod 3 is fixedly connected to one side of the screening frame 23, and the other end passes through the vertical plate 2 and is fixedly connected to the moving block 31. It serves to connect the screening frame 23 and the moving block 31, and can transmit the movement of the moving block 31 to the screening frame 23, so that the screening frame 23 can reciprocate. The strip-shaped drive groove 32 opened at the upper end of the moving block 31 provides space for the movement of the drive slide bar 37, and realizes the transmission of power.

[0034] The support plate 33 is fixedly connected to one side of the upright plate 2, providing a stable mounting platform for the servo motor 34. As a power source, the servo motor 34 can provide stable rotational power. Its output shaft is connected to the rotating shaft 35 through a coupling, transmitting power to the rotating shaft 35 and enabling the rotating shaft 35 to rotate. The rotation of the rotating shaft 35 provides the power foundation for the entire reciprocating motion mechanism.

[0035] The turntable 36, which is fixedly sleeved on one end of the rotating shaft 35, can rotate together with the rotating shaft 35. The drive slide rod 37, which is fixedly connected to the upper end of the turntable 36, will slide in the strip drive through groove 32 of the moving block 31 during the rotation of the turntable 36, thereby pushing the moving block 31 to move back and forth along the direction of the vertical plate 2.

[0036] This method of converting rotary motion into linear reciprocating motion through turntable 36 and drive slide bar 37 can stably provide screening power to screening frame 23, ensuring the smooth progress of ceramic sand screening process and improving screening efficiency.

[0037] The working process of this utility model:

[0038] Step 1: Add ceramic sand raw material into the screening frame 23, start the servo motor 34, the servo motor 34 drives the rotating shaft 35 and the turntable 36 to rotate, drive the slide bar 37 to slide in the strip drive groove 32 of the moving block 31, so that the moving block 31 moves back and forth along the direction of the vertical plate 2, and drives the screening frame 23 and the screen plate 25 to slide back and forth synchronously through the connecting rod 3. Small particles of ceramic sand fall through the holes of the screen plate 25, pass through the guide plate 210 and fall into the collection box 211, and are separated into small particle areas by the partition plate 212;

[0039] Step 2: When large particles accumulate on the screen plate 25 and affect efficiency, turn off the servo motor 34, rotate the stop block 28 to disengage it from the screen plate 25, and pull the screen plate 25 outward using the handle 26. During the pulling, the large ceramic sand particles inside the screen frame are blocked, causing them to fall onto the guide plate 210 and slide into the large particle area of ​​the collection box 211. After cleaning, insert the screen plate 25 back into the slot 24, rotate the stop block 28 to limit the position, restart the equipment to continue screening, and stop the machine as needed after screening is completed. The two sides of the partition 212 inside the collection box 211 are ceramic sand particles of different sizes, which can be removed separately to complete the classification, collection, and subsequent processing.

[0040] 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.
