Description
Technical Field
[0001] The utility model belongs to the technical field of ore screening, and particularly relates to a screening device for potassium feldspar processing. Background Art
[0002] Feldspar is an aluminosilicate mineral of alkali metals or alkaline earth metals such as potassium, sodium, and calcium, also called feldspar group minerals. Potassium feldspar is usually also called orthoclase, which is mainly used in the ceramic industry and has a broad market prospect. During the purification process of potassium feldspar, the potassium feldspar raw material needs to be crushed and then screened. Currently, a circular vibrating screen is mainly used to complete the screening process. However, the crushed potassium feldspar raw material is directly poured onto the high side position of the screen plate at the top of the circular vibrating screen from the feeding hopper, which damages the screen plate, shortens the service life of the screen plate, increases the use cost of the screening equipment, and the crushed potassium feldspar raw material can also fall below the screen plate along the damaged part of the screen plate, reducing the screening effect of the crushed potassium feldspar material. Content of the Utility Model
[0003] In order to solve the above problems, the utility model provides a screening device for potassium feldspar processing.
[0004] The present utility model is realized as follows: A screening device for potassium feldspar processing includes a machine body. An eccentric wheel is provided on one side of the machine body. The eccentric wheel is connected to the transmission shaft of the motor through a transmission belt. The motor drives the machine body to vibrate through the eccentric wheel. The top of the machine body is inclined downwardly provided with a sieve plate. The sieve plate is densely provided with sieve holes. The crushed potassium feldspar raw materials roll down along the sieve plate. The crushed particles meeting the specifications fall into the space below the sieve plate along the sieve holes. A baffle is vertically and fixedly provided at the upper end of the machine body at the outer edge of the sieve plate to block the potassium feldspar crushed materials on the sieve plate. A "U"-shaped first limiting plate is fixedly provided at the upper end of the high side of the sieve plate to limit the position of the base plate. A "U"-shaped second limiting plate is fixedly provided at the upper end of the first limiting plate to limit the position of the cushion plate. The opening directions of the first limiting plate and the second limiting plate are the same and perpendicular to the long side of the sieve plate, which not only facilitates inserting the base plate and the cushion plate into the first limiting plate and the second limiting plate for reliable connection, but also avoids the slipping of the base plate and the cushion plate. The outer walls of the first limiting plate and the second limiting plate are fixedly connected to the inner wall of the baffle, which not only ensures the reliable connection between the first limiting plate and the second limiting plate and the baffle, but also does not form a storage space for the potassium feldspar crushed materials. The inner diameter of the first limiting plate is larger than the inner diameter of the second limiting plate. A base plate is provided inside the first limiting plate. The width of the base plate is the same as the inner width of the first limiting plate to limit the position of the base plate, prevent the base plate from deflecting, and ensure the stable and reliable position of the base plate in the first limiting plate. A cushion plate is fixedly provided at the middle position of the upper end of the base plate. The size of the cushion plate is the same as the inner diameter of the second limiting plate to limit the position of the cushion plate and ensure the stable and reliable position of the cushion plate in the second limiting plate. The potassium feldspar crushed materials poured down from the feeding hopper fall on the cushion plate, collide and impact the cushion plate, protect the sieve plate through the cushion plate, avoid the damage to the sieve plate caused by the potassium feldspar crushed materials, ensure the service life of the sieve plate, and at the same time, it is easy to replace the cushion plate, reducing the maintenance cost of the screening equipment.
[0005] A clamping groove is formed between the end of the second limiting plate, the end of the first limiting plate and the inner wall of the baffle to carry the inserting plate. An inserting plate is vertically provided in the clamping groove to block the through hole. A through hole is opened on the baffle near the inserting plate. The longitudinal sections of the base plate and the cushion plate are the same as the size of the through hole. The positions of the first limiting plate and the second limiting plate correspond to the through hole. The base plate and the cushion plate pass through the through hole and then are inserted into the grooves of the first limiting plate and the second limiting plate. A plurality of first threaded holes are horizontally opened at the upper part of the inserting plate. A plurality of second threaded holes are horizontally opened on the baffle. The positions of the first threaded holes and the second threaded holes correspond to each other and have the same aperture. A bolt is arranged through the first threaded hole and the second threaded hole. A nut is tightly sleeved on the bolt. The nut is tightened to ensure the stable and reliable connection between the inserting plate and the baffle through the bolt, thereby preventing the base plate and the cushion plate from detaching from the through hole.
[0006] Preferably, one ends of the substrate and the backing plate close to the card slot are in the same vertical plane and are in contact with the insertion plate, preventing the substrate and the backing plate from shifting in position, thereby ensuring the blocking effect of the backing plate on the potassium feldspar crushed material.
[0007] Preferably, the length of the insertion plate is the same as the length of the card slot, and the width of the insertion plate is the same as the width of the card slot, ensuring the stability of the position of the insertion plate.
[0008] Preferably, the length of the long side of the first limiting plate is the same as the length of the short side of the sieve plate, ensuring a reliable connection between the first limiting plate, the sieve plate and the baffle, thereby forming a card slot to limit the insertion plate.
[0009] The beneficial effects of the present utility model are as follows: The structure of the present utility model is novel. The positions of the backing plate are limited by the first limiting plate, the second limiting plate and the insertion plate, ensuring the stability of the position of the backing plate. The potassium feldspar crushed material poured from the hopper falls on the backing plate, colliding and impacting the backing plate, protecting the sieve plate through the backing plate, avoiding damage to the sieve plate caused by the potassium feldspar crushed material, ensuring the service life of the sieve plate, and at the same time, it is easy to replace the backing plate, reducing the maintenance cost of the screening equipment.

At the upper end of the machine body 1 located at the outer edge of the sieve plate 5, there is a vertically fixed baffle 7 to block the potassium feldspar crushed material on the sieve plate 5. At the upper end of the high side of the sieve plate 5, there is a "U"-shaped first limiting plate 8 to limit the position of the substrate 10. The length of the long side of the first limiting plate 8 is the same as the length of the short side of the sieve plate 5, ensuring a reliable connection between the first limiting plate 8, the sieve plate 5 and the baffle 7, thereby forming a clamping groove 12 to limit the insertion plate 13.The upper end of the first limiting plate 8 is fixedly provided with a "U"-shaped second limiting plate 9 to limit the position of the backing plate 11. The opening directions of the first limiting plate 8 and the second limiting plate 9 are the same and perpendicular to the long side of the sieve plate 5, which not only facilitates the insertion of the substrate 10 and the backing plate 11 into the first limiting plate 8 and the second limiting plate 9 for reliable connection, but also avoids the slipping of the substrate 10 and the backing plate 11. The outer walls of the first limiting plate 8 and the second limiting plate 9 are fixedly connected to the inner wall of the baffle 7, which not only ensures the reliable connection between the first limiting plate 8 and the second limiting plate 9 and the baffle 7, but also does not form a storage space for the potassium feldspar crushed material. The inner diameter of the first limiting plate 8 is larger than the inner diameter of the second limiting plate 9. A substrate 10 is arranged in the first limiting plate 8, and the width of the substrate 10 is the same as the inner width of the first limiting plate 8 to limit the position of the substrate 10, prevent the substrate 10 from deflecting, and ensure the stable and reliable position of the substrate 10 in the first limiting plate 8.

A clamping groove 12 is formed between the end of the second limiting plate 9, the end of the first limiting plate 8 and the inner wall of the baffle 7 to carry the inserting plate 13.

The positions of the first limiting plate 8 and the second limiting plate 9 correspond to the through hole 14. The substrate 10 and the backing plate 11 pass through the through hole 14 and then are inserted into the grooves of the first limiting plate 8 and the second limiting plate 9. A plurality of first threaded holes 15 are horizontally opened at the upper part of the inserting plate 13, and a plurality of second threaded holes 16 are horizontally opened on the baffle 7.
