Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a chemical material screening device for chemical production. Background Art

[0002] The chemical production process refers to the production process of obtaining valuable products by chemically processing raw materials. Due to the diversity of raw materials and products and the complexity of the production process, tens of thousands of chemical production processes have been formed. The materials needed for chemical production usually need to be screened, so a material screening device for chemical production is needed. During the use of the existing screening device, due to the fixed specifications of the screen, a screen of a certain specification can only screen particles of a specific size. When it is necessary to screen particles of different sizes, the only way to do the screening operation is to replace the screen that is suitable for it, which makes the use of the screening device inconvenient.

[0003] For example, Chinese patent announcement No. CN218797200U discloses a chemical material screening device for chemical production. When in use, a blocking plate and a driving assembly are arranged on the discharge pipe. When the motor rotates, the cam is driven to rotate continuously through the rotating shaft. During the rotation of the cam, the blocking plate continuously reciprocates under the action of the cam, the limit plate and the reset spring, so that the raw materials in the discharge pipe intermittently fall from the through hole into the screening frame. Intermittent discharge of materials can avoid the situation where the raw materials fall into the screening frame in a concentrated manner, which is conducive to improving the screening quality and efficiency.

[0004] However, the chemical material screening device for chemical production in the above application may have certain limitations in that the chemical materials may clog the screen during the screening process, thereby affecting the screening process.

[0005] For this reason, we urgently need to provide a chemical material screening device for chemical production. Utility Model Content

[0006] The purpose of the utility model is to provide a chemical material screening device for chemical production to solve the problem that the chemical materials may clog the screen during the screening process, thereby affecting the screening process.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a chemical material screening device for chemical production, comprising a screening box and a filling pipe, wherein the filling pipe is fixedly connected to the top of the left outer surface of the screening box, a screening device is arranged inside the screening box, and a vibration device is arranged at the bottom of the screening box.

[0008] The screening device comprises two groups of screening units and a dispersing unit.

[0009] The screening unit includes a screening plate, a stretching assembly, a clearing plate, and a discharge pipe. The screening plate is installed obliquely on the upper part of the screening box. Four groups of stretching assemblies are respectively installed inside the four corners of the bottom of the screening plate. The clearing plate is fixedly connected between the four groups of stretching assemblies. The discharge pipe is fixedly connected to the right outer surface of the discharge pipe. When the chemical material is poured into the interior of the screening box through the injection pipe, it falls on the inclined screening plate. Under the action of gravity, the material rolls along the screening plate, and the material with a smaller particle diameter passes through the screening plate and falls to the bottom, while the material with a larger particle rolls to the right side of the screening plate and is discharged through the discharge pipe.

[0010] A further improvement is that screening holes are evenly opened on the upper surfaces of the two screening plates, and the diameter of the screening holes of the upper screening plate is larger than the diameter of the lower screening plate, the two clearing plates correspond vertically to the two screening plates respectively, and the rods on their upper surfaces correspond vertically to the screening holes respectively, the two screening plates cooperate to realize secondary screening of the materials, thereby improving the screening efficiency.

[0011] A further improvement is that the stretching assembly includes a sliding sleeve, an electromagnet, a stretching spring, and a sliding rod. The sliding sleeve is installed inside the bottom of the screening plate, the electromagnet is installed on the top wall of the sliding sleeve, the stretching spring is fixedly connected to the bottom of the electromagnet, the sliding rod is installed at the bottom of the stretching spring, and its bottom is connected to the clearing plate.

[0012] A further improvement is that the diameter of the sliding rod is the same as the inner diameter of the sliding sleeve, and is slidably connected to the inner wall of the sliding sleeve. The sliding rod is made of magnetic material. When the screening plate is blocked by materials, the electromagnet is energized to generate suction between the sliding rod and the sliding rod, pulling the sliding rod to slide upward inside the sliding sleeve, thereby driving the clearing plate to move upward, and the blockage inside the screening hole on the screening plate is pushed out by the clearing plate.

[0013] A further improvement is that the dispersion unit includes a bearing seat, a rotating shaft, and a dispersion plate. The two bearing seats are respectively fixedly connected to the front and rear sides of the upper surface of the screening plate, the rotating shaft is rotatably connected to the inside of the bearing seat, and the five dispersion plates are respectively fixedly connected to the outer surface of the rotating shaft in a ring shape. When the material rolls along the screening plate, its downward impact force hits the dispersion plate, causing the rotating shaft inside the bearing seat to rotate inside the bearing seat, thereby dispersing the agglomerated material, which is more conducive to the screening work.

[0014] A further improvement is that a discharge plate is installed at an angle at the inner bottom of the screening box, and a discharge pipe is also fixedly connected to the bottom of the left outer surface of the screening box. An observation window is provided on the front of the screening box. Materials with smaller particle diameters that continuously pass through the two screening plates fall onto the discharge plate and are discharged through the discharge pipe on the left side of the inclined discharge plate, completing the three-level screening of the material, and the screening situation inside the screening box can be observed in real time through the observation window.

[0015] A further improvement is that the vibration device includes a vibration motor, a supporting foot, a vibration spring, and a limit rod. The vibration motor is installed at the bottom center of the screening box. The four supporting feet are respectively installed at the four corners of the lower surface of the screening box. The four vibration springs are respectively fixedly connected between the screening box and the supporting feet, and the upper surface of the supporting feet is provided with sliding holes. The four limit rods are respectively slidably connected to the inside of the sliding holes, and the tops of the limit rods are connected to the screening box. While screening, the vibration motor is started to drive the screening box to vibrate. At the same time, the vibration spring is driven to vibrate up and down, thereby driving the entire screening box to vibrate, so as to better screen and classify the materials.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The chemical material screening device for chemical production, when the chemical material is poured into the screening box through the injection pipe, it falls on the inclined screening plate. Under the action of gravity, the material rolls along the screening plate, and the material with smaller particle diameter passes through the screening plate and falls to the bottom, while the material with larger particle diameter rolls to the right side of the screening plate and is discharged through the discharge pipe.

[0018] 2.

At the same time, it drives the vibration spring to vibrate up and down, thereby driving the entire screening box to vibrate, so as to better screen and classify the materials.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 5 , the utility model provides a technical solution: Example

[0030] The screening device comprises two groups of screening units.

[0031] The screening unit includes a screening plate 301, a stretching assembly 302, a clearing plate 303, and a discharge pipe 304. The screening plate 301 is installed obliquely on the upper part of the screening box 1. Four groups of stretching assemblies 302 are respectively installed inside the four corners of the bottom of the screening plate 301. The clearing plate 303 is fixedly connected between the four groups of stretching assemblies 302. The discharge pipe 304 is fixedly connected to the right outer surface of the discharge pipe 304. When the chemical material is poured into the interior of the screening box 1 through the injection pipe 2, it falls on the inclined screening plate 301. Under the action of gravity, the material rolls along the screening plate 301. The material with a smaller particle diameter passes through the screening plate 301 and falls to the bottom, and the material with a larger particle size rolls to the right side of the screening plate 301 and is discharged through the discharge pipe 304.

[0032] Screening holes are evenly arranged on the upper surfaces of the two screening plates 301, and the diameter of the screening holes of the upper screening plate 301 is larger than that of the lower screening plate 301. The two clearing plates 303 are respectively vertically corresponding to the two screening plates 301, and the rods on their upper surfaces are respectively vertically corresponding to the screening holes. The two screening plates 301 cooperate to realize secondary screening of the materials, thereby improving the screening efficiency.

[0033] The stretching assembly 302 includes a sleeve 3021, an electromagnet 3022, a stretching spring 3023, and a slide rod 3024. The sleeve 3021 is installed inside the bottom of the screening plate 301, the electromagnet 3022 is installed on the top wall of the sleeve 3021, the stretching spring 3023 is fixedly connected to the bottom of the electromagnet 3022, the slide rod 3024 is installed at the bottom of the stretching spring 3023, and its bottom is connected to the clearing plate 303.

The slide rod 3024 is made of magnetic material. When the screening plate 301 is blocked by materials, the electromagnet 3022 is energized, thereby generating suction between the slide rod 3024 and the slide rod 3024, pulling the slide rod 3024 to slide upward inside the sleeve 3021, thereby driving the clearing plate 303 to move upward, and the blockage inside the screening hole on the screening plate 301 is pushed out by the clearing plate 303.

[0035] A discharge plate 308 is installed obliquely at the bottom of the inner part of the screening box 1, and a discharge pipe 304 is also fixedly connected to the bottom of the left outer surface of the screening box 1. An observation window 309 is opened on the front of the screening box 1. Materials with smaller particle diameters that continuously pass through the two screening plates 301 fall onto the discharge plate 308, and are discharged through the discharge pipe 304 on the left side along the obliquely arranged discharge plate 308, completing the three-level screening of the material, and the screening situation inside the screening box 1 can be observed in real time through the observation window 309.

[0036] The vibration device includes a vibration motor 401, a support foot 402, a vibration spring 403, and a limit rod 404.

While screening, the vibration motor 401 is started to drive the screening box 1 to vibrate. At the same time, the vibration spring 403 is driven to vibrate up and down, thereby driving the screening box 1 to vibrate as a whole, so as to better screen and classify the materials. Example

[0037] On the basis of Example 1, the screening device also includes a dispersion unit, which includes a bearing seat 305, a rotating shaft 306, and a dispersion plate 307.
