Description

TECHNICAL FIELD

[0001] The application relates to the technical field of limestone processing, in particular to a limestone production screening processing device. BACKGROUND

[0002] Limestone is a common material in daily life, is a main raw material for producing glass, and is used as a large amount of building material, and different specifications of limestone are required for different industries, so a screening device is required to screen limestone particle raw materials of different sizes.

[0003] At present, a general screening device comprises a fixed frame and a screen frame installed on the fixed frame, the screen frame is driven to reciprocate through an eccentric wheel or a crank connecting rod mechanism, so that the limestone repeatedly jumps on the screen, and finally screening is realized.

[0004] However, during the screening process, the shaking screen is prone to generate a large noise, and the screening efficiency is not high. CONTENT OF THE UTILITY MODEL

[0005] In order to improve the screening efficiency of limestone, the application provides a limestone production screening processing device.

[0006] The limestone production screening processing device provided by the application adopts the following technical scheme:

[0007] A limestone production screening processing device comprises:

[0008] A box body is provided with a feeding pipe at the top end;

[0009] A plurality of screening plates are arranged along the height direction of the box body, and the accuracy of the screening plates increases in sequence along the direction away from the feeding pipe, one end of the screening plate is hinged to the inner wall of the box body, and the other end is movably connected to the box body;

[0010] A plurality of pressure springs are provided, and the pressure springs are in one-to-one correspondence with the screening plates, and the two ends of the pressure spring are fixedly connected to the screening plate and the box body;

[0011] In the initial state, the pressure spring is in a compressed state;

[0012] A driving assembly is arranged on the box body;

[0013] A plurality of transmission assemblies are arranged, and the transmission assemblies are in one-to-one correspondence with the screening plates, the transmission assembly is arranged on the box body, and the driving assembly is used to drive the transmission assembly to rotate.

[0014] By adopting the technical scheme, the lime is put in through the feeding pipe, and in the initial state, the pressure spring is in the compressed state, thereby providing a certain pre-tightening force for the screening plate; the driving assembly drives the transmission assembly to rotate, and under the action of the pressure spring, the transmission assembly drives one end of the screening plate to reciprocate up and down.

[0015] By hinging the screening plate, the screening plate can swing when impacted and vibrated by the lime, which is helpful for uniform distribution and rapid screening of the lime on the screen surface; under the action of multi-stage screening, the lime can be screened multiple times during falling, thereby ensuring that lime of different particle sizes can be effectively separated, so as to easily improve the screening efficiency.

[0016] Optionally, the driving assembly comprises:

[0017] The motor is fixedly arranged on the box body.

[0018] The rotating rod is fixedly connected to the output shaft of the motor.

[0019] The connecting rod is rotatably connected to one end of the rotating rod away from the motor.

[0020] The swinging rod is rotatably connected to one end of the connecting rod away from the rotating rod.

[0021] By adopting the technical scheme, the motor drives the rotating rod to rotate, so that the connecting rod can swing with the rotation of the rotating rod, and the swinging rod can swing with the swinging of the connecting rod, thereby driving the screening plate to vibrate, so as to improve the reliability and efficiency of transmission.

[0022] Optionally, the transmission assembly comprises:

[0023] The driving wheels are rotatably connected to the box body, and one of the driving wheels is fixedly connected to one end of the swinging rod.

[0024] The plurality of driving wheels are collectively sleeved with a synchronous belt.

[0025] The cam is coaxially fixedly connected to the driving wheels and located below the screening plate.

[0026] By adopting the technical scheme, the swinging rod drives the driving wheels to rotate, all the driving wheels are driven to rotate through the synchronous belt, and the cam is driven to rotate by the driving wheels, so that the screening plate is lifted and vibrated when the driving wheels rotate, and the screening plate is periodically vibrated, thereby helping the lime to be uniformly distributed and rapidly screened on the screen surface.

[0027] Optionally, a pad is fixedly arranged at the bottom end of the screening plate, and the pad abuts against the tip end of the cam.

[0028] By adopting the above technical scheme, when the cam rotates, the tip end of the cam will periodically lift the pad, causing the screening plate to vibrate, which helps the uniform distribution and rapid screening of the lime on the screening surface.

[0029] In addition, when the tip end of the cam lifts the pad, the pad can absorb part of the vibration energy, reducing the impact of vibration on the screening plate and the cam, thereby easily protecting the equipment from damage.

[0030] Optionally, a plurality of accommodation grooves are formed in the inner wall of the box, and the plurality of accommodation grooves correspond one-to-one to the plurality of screening plates. An end of the screening plate away from the hinged end extends into the accommodation groove. A reset plate is hinged to one end of the screening plate, and the reset plate is located in the accommodation groove.

[0031] By adopting the above technical scheme, the accommodation groove provides a stable support point for the screening plate, which helps to reduce the shaking and deviation of the screening plate during vibration, thereby improving the stability and efficiency of screening.

[0032] When the screening plate vibrates, the reset plate swings, making it difficult for lime to enter the accommodation groove, reducing the possibility of lime accumulation and blockage.

[0033] Optionally, a torsional spring is arranged at the connection between the reset plate and the screening plate. The two ends of the torsional spring are respectively fixedly connected to the reset plate and the screening plate. In the initial state, the torsional spring is in a compressed state.

[0034] By adopting the above technical scheme, the reset plate can always fit the accommodation groove, further making it difficult for lime to enter the accommodation groove, reducing the possibility of lime accumulation and blockage.

[0035] Optionally, a plurality of discharge outlets are formed in the box, and the plurality of discharge outlets are arranged along the height direction of the box. The discharge outlets are located at the hinged portions of the screening plates.

[0036] By adopting the above technical scheme, lime of different particle sizes can be smoothly discharged from different discharge outlets, reducing the accumulation of lime inside the box.

[0037] Optionally, a guide plate is fixedly arranged at the discharge outlet, and the guide plate is inclinedly arranged along the horizontal direction towards the vertical downward direction.

[0038] By adopting the above technical scheme, the inclined guide plate makes it easier for the lime to slide downward along the plate surface under the action of gravity, thereby smoothly leaving the discharge outlet, reducing the accumulation and blockage of the lime at the discharge outlet, thereby easily realizing the graded discharge of the lime, so that materials of different particle sizes can be collected at different discharge outlets, thereby improving the precision and efficiency of screening.

[0039] Optionally, a protective shell is fixedly arranged above the guide plate.

[0040] By adopting the technical scheme, the protective shell can block lime splashing and reduce the loss of lime in the screening process, thereby facilitating the improvement of the accuracy and efficiency of screening.

[0041] Optionally, the end of the feeding pipe away from the box body is flared.

[0042] By adopting the technical scheme, the caliber of the feeding pipe is increased, so that the material can enter the screening equipment more smoothly, thereby facilitating the reduction of the blockage and retention of the material in the feeding process, and further improving the feeding efficiency.

[0043] To sum up, the present application has at least one of the following beneficial technical effects:

[0044] By arranging multiple screening plates along the height direction of the box body and increasing the accuracy in sequence, effective classification of lime materials of different particle sizes is achieved, and the screening accuracy and efficiency are improved.

[0045] By the synergistic effect of the pressure spring and the transmission assembly, the screening plate can automatically adjust the inclination angle during vibration, avoiding the problem of easy blockage of the traditional screen, and reducing the cleaning difficulty.

[0046] The driving assembly adopts a motor, a rotating rod and a connecting rod structure, combined with the design of multiple transmission assemblies and cams, which not only ensures the stability and reliability during screening, but also reduces the noise during equipment operation and improves the working environment.
