Description

Technical Field

[0001] This utility model relates to the field of horizontal vibrating screen basket technology, specifically, to a novel horizontal vibrating screen basket. Background Technology

[0002] Horizontal vibrating centrifuges are widely used in dewatering operations in industries such as mining, coal, petroleum, fertilizer, grain, and environmental protection. The screen basket is one of the key components of the centrifuge, being a high-speed rotating part. During operation, the material enters the bottom of the screen basket through the feed pipe along the screen base. Under centrifugal force, the material inside the basket adheres tightly to the screen surface. Under the action of vibration, the material layer moves evenly towards the larger end of the screen basket. The dewatered material is thrown out from the larger end of the screen basket and falls into the discharge port at the bottom of the machine casing, where it is discharged downwards. Water in the material, under centrifugal force, permeates through the material layer and screen gaps, is thrown to the sides of the machine casing, and flows along the inner wall to the drain outlet for discharge.

[0003] However, the existing screen baskets have large screen bar widths and large gaps between screen bars, resulting in poor dewatering effect, short service life, and easy damage. Therefore, a new type of horizontal vibrating screen basket is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a new type of horizontal vibrating screen basket, which solves the problems of poor dewatering effect, short service life and easy damage caused by the large width of the screen bars and the large spacing between the screen bars in the existing screen baskets.

[0005] This utility model provides the following technical solution: a novel horizontal vibrating screen basket, comprising a screen basket, wherein a plurality of screen frames are fixedly connected to the side ends of the screen basket, a plurality of support bars are fixedly connected between the side ends of each screen frame, a plurality of first screen bars are fixedly connected between the side ends of each screen frame, a plurality of screen bar assemblies are provided between the side ends of every two sets of screen frames, a plurality of connecting mechanisms are provided on the inner side end of each screen bar assembly, a plurality of side plates are fixedly connected to the outer side end of each screen bar assembly, and a connecting frame is provided between the side ends of every two sets of side plates.

[0006] As a preferred embodiment of the above technical solution, the connecting mechanism includes a crossbeam, which is fixedly connected to the inner end of the screen bar assembly. A top plate is fixedly connected to the top of the crossbeam, and bolts are threaded to the side end of the top plate.

[0007] As a preferred embodiment of the above technical solution, each of the screen frames has several screw holes on its side, and the bolts are adapted to the screw holes.

[0008] As a preferred embodiment of the above technical solution, each of the screen bar assemblies is staggered between the side ends of a plurality of first screen bars.

[0009] As a preferred embodiment of the above technical solution, each of the crossbeams is located at the top of each first screen bar, and each of the connecting frames is located at the top of each support bar.

[0010] As a preferred embodiment of the above technical solution, each connecting frame is fixedly connected to two side frames on both the left and right sides, each side frame is rotatably disposed on the outer side of each side plate, each side frame has a circular groove inside, and each circular groove has a limiting mechanism inside.

[0011] As a preferred embodiment of the above technical solution, the limiting mechanism includes a round rod, which is inserted from the outer end of the side frame into the interior of the round groove. A round plate is fixedly connected to the side end of the round rod, a spring is sleeved on the outer end of the round rod, a horizontal plate is fixedly connected to the side end of the round rod, and an insert plate is fixedly connected to the side end of the horizontal plate. The side end of the insert plate is inserted into the side plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention places the screen bar assemblies alternately between the side ends of several first screen bars. Each crossbeam is located at the top of each first screen bar, each connecting frame at the top of each support bar, and each top plate at the side end of each screen frame. The screw holes on the side ends of each top plate are aligned with the screw holes on the side ends of each screen frame. Bolts are threaded into the screw holes between the top plate and the side ends of the screen frame, and then secured with nuts. This fixes the top plate to the screen frame, completing the fixation of the screen bar assemblies. By reducing the width of the first screen bars and the screen bar assemblies, and by improving the fit between the screen bar assemblies and the first screen bars, the spacing between the screen bars is reduced, increasing the screen bar density and thus improving the dewatering effect of the horizontal vibrating screen basket. The increased number of screen bar assemblies also extends the service life of the screen basket and makes it less prone to damage. Attached Figure Description

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] like Figure 1-4 As shown, this utility model provides a technical solution: a novel horizontal vibrating screen basket, including a screen basket 1. Several screen frames 101 are fixedly connected to the side ends of the screen basket 1. Several support bars 103 are fixedly connected between the side ends of each screen frame 101. Several first screen bars 104 are fixedly connected between the side ends of each screen frame 101. Several screen bar assemblies 2 are provided between the side ends of every two sets of screen frames 101. Several connecting mechanisms 3 are provided on the inner side end of each screen bar assembly 2. Several side plates 201 are fixedly connected to the outer side end of each screen bar assembly 2. A connecting frame 4 is provided between the side ends of every two sets of side plates 201. By staggering the placement of the screen bar assemblies 2 between the side ends of several first screen bars 104, and by using several connecting mechanisms 3, the screen bar assemblies 2 are fixed. This reduces the size of the first screen bars 104 and the screen bar assemblies 2. The width, and the cooperation between the screen bar assembly 2 and the first screen bar 104, reduces the gap between the screen bars and increases the screen bar density, thereby improving the dewatering effect of the horizontal vibrating screen basket 1, extending the service life of the screen basket 1, and making the screen basket 1 less prone to damage. Each connecting frame 4 has a side frame 401 fixedly connected to its left and right sides. Each side frame 401 is rotatably set on the outer side of each side plate 201. Each side frame 401 has a circular groove 402 inside, and each circular groove 402 has a limiting mechanism 5 inside. The setting of the connecting frame 4 makes it easy to fold and store several screen bar assemblies 2 before installation, and facilitates the transportation of screen bar assemblies 2. The setting of the limiting mechanism 5 makes it easy to fix several screen bar assemblies 2 after unfolding, thereby improving the stability of several screen bar assemblies 2 installed between several screen frames 101.

[0021] As one implementation method in this embodiment, such as Figure 1 and Figure 3As shown, the connecting mechanism 3 includes a crossbeam 301, which is fixedly connected to the inner end of the screen bar assembly 2. A top plate 302 is fixedly connected to the top of the crossbeam 301, and bolts 303 are threadedly connected to the side end of the top plate 302. Each screen frame 101 has several screw holes 102 on its side end, and the bolts 303 are adapted to the screw holes 102. Each screen bar assembly 2 is staggered between the side ends of several first screen bars 104. Each crossbeam 301 is located at the top of each first screen bar 104, and each connecting frame 4 is located at the top of each support bar 103. In practice, by staggering the screen bar assemblies 2 between the side ends of several first screen bars 104, each crossbeam 301 is located at the top of each first screen bar 104, each connecting frame 4 is located at the top of each support bar 103, and each top plate 302 is located at the top of each first screen bar 104. At the side end of each screen frame 101, the screw holes 102 on the side end of each top plate 302 are aligned with the screw holes 102 on the side end of each screen frame 101. Bolts 303 are then threaded into the screw holes 102 between the top plate 302 and the side end of the screen frame 101, and then secured with nuts. This fixes the top plate 302 to the screen frame 101, completing the fixation of the screen bar assembly 2. By reducing the width of the first screen bar 104 and the screen bar assembly 2, and by improving the fit between the screen bar assembly 2 and the first screen bar 104, the spacing between the screen bars is reduced, increasing the screen bar density. This improves the dewatering effect of the horizontal vibrating screen basket 1, extends the service life of the screen basket 1, and makes the screen basket 1 less prone to damage. When the screen bar assembly 2 is damaged, it can be replaced to restore normal use of the screen basket 1.

[0022] As one implementation method in this embodiment, such as Figure 2 , Figure 3 and Figure 4 As shown, the limiting mechanism 5 includes a round rod 501, which is inserted from the outer end of the side frame 401 into the interior of the round groove 402. A round plate 502 is fixedly connected to the side end of the round rod 501, and a spring 503 is sleeved on the outer end of the round rod 501. A horizontal plate 504 is fixedly connected to the side end of the round rod 501, and an insert plate 505 is fixedly connected to the side end of the horizontal plate 504. The side end of the insert plate 505 is inserted into a slot opened on the side end of the side plate 201. In practice, by pulling the horizontal plate 504, the horizontal plate 504 drives the round rod 501 and the round plate 502 to move. The round plate 502 retracts by pressing against the spring 503, which causes the insert plate 505 to move out of the slot opened on the side end of the side plate 201. At this time, the insert plate 505 no longer limits the side plate 201, and the screen bar assembly 2 can be rotated. Figure 2Several screen bar assemblies 2 are rotated from a flat state to a stacked and folded state, which facilitates the storage and transportation of the screen bar assemblies 2. Subsequently, after the screen bar assemblies 2 are unfolded into a flat state, the horizontal plate 504 is pulled so that the insert plate 505 is aligned with the slot opened at the side end of the side plate 201. At this time, after the horizontal plate 504 is released, the spring 503 pushes the round plate 502 back, which drives the round rod 501, the horizontal plate 504 and the insert plate 505 to move. At this time, the insert plate 505 can be inserted into the slot opened at the side end of the side plate 201, thereby limiting and fixing the side plate 201, so that the side plate 201 and the screen bar assemblies 2 cannot rotate, which facilitates the fixing of the unfolded screen bar assemblies 2, thereby improving the stability of the screen bar assemblies 2 installed between the screen frames 101.

[0023] Working principle: By staggering the placement of the screen bar assemblies 2 between the side ends of several first screen bars 104, each crossbeam 301 is located at the top of each first screen bar 104, each connecting frame 4 is located at the top of each support bar 103, and each top plate 302 is located at the side end of each screen frame 101. The screw holes 102 on the side end of each top plate 302 are aligned with the screw holes 102 on the side end of each screen frame 101. Bolts 303 are then threaded into the screw holes 102 between the top plate 302 and the side end of the screen frame 101. Next, the bolts 303 are fixed with nuts, and the top plate 302 is fixed to the screen frame 101. At this time, the screen bar assembly 2 is fixed. By reducing the width of the first screen bar 104 and the screen bar assembly 2, and by cooperating with the first screen bar 104, the distance between the screen bars is reduced, the screen bar density is increased, and the dewatering effect of the horizontal vibrating screen basket 1 is improved. Due to the increase of the screen bar assembly 2, the service life of the screen basket 1 is extended, and the screen basket 1 is less prone to damage.

[0024] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
