Description

Technical Field

[0001] This utility model relates to the field of screening technology, and in particular to a screening device for the final material of aluminum trichloride production. Background Technology

[0002] Aluminum trichloride is a widely used compound, primarily as a catalyst. In organic synthesis, petrochemicals, and pharmaceuticals, aluminum trichloride catalyzes various reactions such as esterification, alkylation, and olefin polymerization, thereby increasing reaction rates and product yields. During production, aluminum trichloride gas enters a collector through a sublimation tube and naturally cools and sublimates, forming aluminum trichloride crystals that deposit inside the collector. The collected material is then discharged from the collector and conveyed to a screening device via a screw conveyor.

[0003] A search revealed that CN217411466U discloses a screening device for the final material of aluminum trichloride production. This device uses an anti-stacking mechanism to sweep away the accumulated aluminum trichloride crystals with a sweeping rod. At the same time, the bottom of the swivel teeth contacts the top surface of the screening screen to clean the aluminum trichloride crystals that are clogging the screen, thus reducing the problem of uneven accumulation density caused by vibration during the screening process.

[0004] However, the aforementioned device also carries the risk of clogging in the feed holes of the spiral tube. Once clogged, cleaning becomes more difficult. Furthermore, when material is discharged from the hopper into the spiral tube, more material is discharged from the feed holes closer to the hopper, and less material is discharged from the feed holes farther away, resulting in uneven discharge. In addition, after screening, coarse material on the surface of the screening screen is difficult to remove from the sealing door, thus requiring further improvement. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a final material screening device for aluminum trichloride production.

[0007] Furthermore, the support assembly includes a vertical rod fixed to the lower surface of the discharge hopper, a vertical tube slidably sleeved on the bottom surface of the vertical rod, and a spring fixedly connected to the bottom wall of the vertical tube and the bottom end of the vertical rod.

[0008] Furthermore, the adjustment assembly includes a support tube hinged to the outer wall of the housing, a support rod slidably connected inside the support tube, the other end of the support rod being hinged to the lower surface of the sieve plate, and a locking bolt threaded through the top side wall of the support tube.

[0009] Furthermore, the swing assembly includes a guide rod fixed inside the housing and a servo motor fixed outside the housing. A slide block is slidably sleeved on the surface of the guide rod. A lead screw is fixedly connected to the drive end of the servo motor. The lead screw extends into the housing and passes through the slide block and is threadedly connected to the slide block. The slide block is fixedly connected to a rigid tube.

[0010] Furthermore, the crushing assembly includes two horizontal shafts rotatably connected to the inner wall of the feeding hopper and a drive motor fixed to the outer wall of the feeding hopper. Each of the two horizontal shafts is fixedly connected to a squeezing roller, and each of the two horizontal shafts is fixedly connected to a gear at one end outside the feeding hopper.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-4As shown, a screening device for final material in aluminum trichloride production is disclosed, comprising a housing 1, an opening 2 on one side of the housing 1, an inclined screen plate 3 penetrating through the opening 2 and the interior of the housing 1, one end of the screen plate 3 inside the housing 1 being rotatably connected to the inner wall of the housing 1, an adjusting component 4 for adjusting the inclination of the screen plate 3 being provided on the outer wall of the housing 1 below the opening 2, a discharge hopper 6 being installed at the bottom of the housing 1, multiple support components 5 being fixed on the lower surface of the discharge hopper 6, and a vibrating motor 7 being fixed on the lower surface of the discharge hopper 6, a feeding hopper 8 being fixed at the top of the housing 1 and on the side near the rotating screen plate 3, a flexible hose 9 being fixedly connected to the bottom of the feeding hopper 8, and a rigid pipe 10 being fixedly connected to the bottom end of the flexible hose 9, a swinging component 11 for driving the rigid pipe 10 to move being provided inside the housing 1, and a crushing component 12 being installed inside the feeding hopper 8.

[0024] In this embodiment, a PLC controller is installed on the surface of the housing 1. The controller model can be selected according to actual production. In this embodiment, the controller adopts the Siemens S7-200 series programmable controller, which controls the operation of various electronic components of the device.

[0025] The support assembly 5 includes a vertical rod 51 fixed to the lower surface of the discharge hopper 6, a vertical tube 52 slidably sleeved on the bottom surface of the vertical rod 51, and a spring 53 fixedly connected to the bottom wall of the vertical tube 52 and the bottom of the vertical rod 51.

[0026] The vertical tube 52 can slide up and down along the surface of the vertical rod 51, and the spring 53 can play a supporting role. Therefore, when the vibration motor 7 is started to vibrate the box 1, the spring 53 can amplify the vibration effect, thereby improving the vibration effect of the screen plate 3 and improving the screening efficiency.

[0027] The adjustment assembly 4 includes a support tube 41 hinged to the outer wall of the housing 1, a support rod 42 slidably connected inside the support tube 41, the other end of the support rod 42 being hinged to the lower surface of the sieve plate 3, and a locking bolt 43 threaded through the top side wall of the support tube 41.

[0028] The length of the entire adjusting assembly 4 can be changed by moving the support rod 42 inside the support tube 41, thereby adjusting the height of the screen plate 3 on the side closer to the opening 2, thus adjusting the tilt angle of the screen plate 3. The support rod 42 can then be fixed by tightening the locking bolt 43.

[0029] The swing assembly 11 includes a guide rod 111 fixed inside the housing 1 and a servo motor 114 fixed outside the housing 1. A slide block 112 is slidably sleeved on the surface of the guide rod 111. A lead screw 113 is fixedly connected to the drive end of the servo motor 114. The lead screw 113 extends into the housing 1 and passes through the slide block 112 and is threadedly connected to the slide block 112. The slide block 112 is fixedly connected to the rigid tube 10.

[0030] When the servo motor 114 drives the lead screw 113 to rotate, the lead screw 113 will drive the slide 112 to move along the guide rod 111, thereby driving the rigid tube 10 to move above the screen plate 3. Therefore, by controlling the servo motor 114 to rotate regularly in both directions, the rigid tube 10 can be driven to move back and forth on the surface of the screen plate 3, so that the material discharged from the bottom of the feeding hopper 8 can be evenly dispersed on the surface of the screen plate 3, avoiding material accumulation in one place.

[0031] The crushing assembly 12 includes two horizontal shafts 121 rotatably connected to the inner wall of the feeding hopper 8 and a drive motor 124 fixed to the outer wall of the feeding hopper 8. Each of the two horizontal shafts 121 is fixedly connected to a squeezing roller 122, and each of the two horizontal shafts 121 located outside the feeding hopper 8 is fixedly connected to a gear 123. The two gears 123 mesh with each other, and the output end of the drive motor 124 is fixedly connected to either of the horizontal shafts 121.

[0032] With the meshing action of the two gears 123, the drive motor 124 can drive the two extrusion rollers 122 to rotate in opposite directions. When material is added into the feeding hopper 8, the two extrusion rollers 122 can extrude and crush the material.

[0033] Inclined guide plates 125 are fixed inside the feeding hopper 8 and above the two extrusion rollers 122. The function of the guide plates 125 is to guide the material into the gap between the two extrusion rollers 122.

[0034] Working principle: First, aluminum trichloride final material is added into the feeding hopper 8. Then, the drive motor 124, servo motor 114 and vibration motor 7 are started. The material is crushed under the pressure of two extrusion rollers 122. The crushed material is then discharged along the hose 9 and the rigid pipe 10. The servo motor 114 can drive the rigid pipe 10 to swing back and forth, so that the material is evenly dispersed on the surface of the screen plate 3. The material is then screened by the vibrating screen plate 3. The fine material is discharged from the discharge hopper 6, and the coarse material is discharged from the opening 2 along the screen plate 3. At this time, the coarse material can be collected by the collection box, which is convenient for subsequent reintroduction into the feeding hopper 8 for crushing.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to any specific implementation. Clearly, many modifications and variations can be made based on the content of this specification.
