Description

Technical Field

[0001] The utility model belongs to the technical field of refractory material production, and particularly relates to a screening device for refractory material production. Background Art

[0002] Refractory is a material with high temperature resistance, chemical corrosion resistance and wear resistance. It is often used in the lining, furnace, furnace wall and other parts of high-temperature industrial equipment to protect the equipment from high temperature, corrosion and wear. The screening device for refractory production is a device used to produce refractory materials, which is used to screen and grade raw materials. It is usually composed of a screen, a screen frame, a vibration mechanism, etc. The raw materials are screened on the screen through vibration to separate refractory particles of different sizes. The existing screening device for refractory production will be damaged during use and needs to be replaced, but the personnel cannot quickly replace the screen.

[0003] For example, the utility model with announcement number CN219324449U discloses a raw material screening device for the production of refractory dry materials. Screens and discharge plates are spaced apart from top to bottom in the screen box. In this patent scheme, when the screen is worn, blocked, or needs to be replaced with a different aperture specification, the screen is not convenient to disassemble and replace. The inability to quickly replace the screen will result in extended downtime, which will directly affect the efficiency of refractory material screening. Utility Model Content

[0004] In view of this, the utility model aims at the deficiencies of the prior art and provides a screening device for refractory production, which can not only screen the refractory but also quickly replace the screening net to reduce downtime, save production time and improve production efficiency.

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is: a screening device for refractory material production, including a mounting frame, a screening box is arranged inside the mounting frame, a feeding port is opened at the upper end of the screening box, a discharging box is arranged at the discharging port opened at the lower end of the screening box, a connecting plate is arranged inside the screening box, a mounting plate is slidably connected to the upper end of the connecting plate, four springs are arranged between the connecting plate and the mounting plate, vibration motors are arranged on the left and right sides of the mounting plate respectively, a screening net is slidably arranged inside the mounting plate, and locking mechanisms for locking the screening net are arranged on the left and right sides of the mounting plate, and the lock mechanism is used to lock the screening net. The stopping mechanism includes rotating columns rotatably arranged on the left and right sides of the mounting plate, pull plates are fixedly sleeved on the outer arc surfaces of the two rotating columns, locking columns are arranged on the opposite inner sides of the two pull plates, locking holes are respectively opened on the left and right sides of the screening net, and the two locking columns pass through the through holes opened on the left and right sides of the mounting plate and are respectively plugged into adjacent locking holes, and limiting disks are arranged on the opposite outer ends of the two rotating columns, and an elastic reset component is arranged between the limiting disk and the pull plate, and the elastic reset component includes two springs arranged between the pull plate and the limiting disk, and the two springs are respectively sleeved on the corresponding outer arc surfaces of the rotating columns.

[0006] As a further improvement of the utility model, an observation window is arranged in the installation opening opened on the right side of the screening box.

[0007] As a further improvement of the utility model, a control panel is arranged on the front side of the screening box, and the vibration motor is electrically connected to the control panel.

[0008] As a further improvement of the utility model, pads are respectively welded and fixed at the four corners of the lower end of the mounting frame.

[0009] As a further improvement of the utility model, evenly distributed anti-slip protrusions are provided on both the upper and lower ends of the pull plate.

[0010] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0011] Firstly, by controlling the operation of the vibration motor and cooperating with a pair of springs to achieve vibration of the screening net on the mounting plate, the personnel then add the refractory material to be screened into the screening box from the feed port, and the refractory material falls onto the vibrating screening net. The refractory material larger than the screen hole of the screening net cannot pass through the screen hole and will slide out of the screening box from the inclined screening net during the vibration process, while the refractory material smaller than the screen hole of the screening net will pass through the screen hole and fall out of the discharge box, so that the refractory material can be screened quickly.

[0012] Secondly, during the screening process of refractory materials, personnel can observe the screening situation of refractory materials in real time through the observation window, and can promptly discover the blockage between refractory materials and the screening net, which is convenient for personnel to discover problems that occur during the operation of the screening device.

[0013] Thirdly, by pulling the pull plates on both sides, the locking column is made to leave the locking hole, and then the pull plate is rotated to make the locking column on its upper end misaligned with the locking hole. At this time, spring two is in a compressed state, and then the personnel takes out the worn screening net, and then slides the new screening plate into the interior of the mounting plate, and then rotates the pull plate to make the locking column on its upper end correspond to the locking hole, and then releases the pull plate. At this time, spring two rebounds quickly and drives the locking column to insert into the interior of the jack to complete the limit locking of the screening net. The screening net can be quickly replaced, which can reduce downtime, save production time, and improve production efficiency.

[0014] Fourthly, the contact area between the screening device and the ground is increased by the feet on the mounting frame, making the operation of the screening device more stable. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] In order to better understand the present invention, the content of the present invention is further clearly described below in conjunction with the embodiments, but the protection content of the present invention is not limited to the following embodiments. In the following description, a large number of specific details are given in order to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0022] like Figure 1 , 2As shown in Figures 3 and 4, a screening device for refractory material production comprises a mounting frame 101, a screening box 102 is arranged inside the mounting frame 101, a feed port 104 is opened at the upper end of the screening box 102, a discharge box 103 is arranged at the discharge port opened at the lower end of the screening box 102, a connecting plate 203 is arranged inside the screening box 102, a mounting plate 201 is slidably connected to the upper end of the connecting plate 203, four springs 202 are arranged between the connecting plate 203 and the mounting plate 201, vibration motors 204 are respectively arranged on the left and right sides of the mounting plate 201, a screening net 301 is slidably arranged inside the mounting plate 201, and locking mechanisms for locking the screening net 301 are arranged on the left and right sides of the mounting plate 201.

[0023] like Figure 1 , 2 As shown in , 3 and 4, the locking mechanism includes a rotating column 306 rotatably set on the left and right sides of the mounting plate 201, a pull plate 302 is fixedly sleeved on the outer arc surface of the two rotating columns 306, and locking columns 303 are set on the opposite inner sides of the two pull plates 302. Locking holes are respectively opened on the left and right sides of the screening net 301, and the two locking columns 303 pass through the through holes opened on the left and right sides of the mounting plate 201 and are respectively plugged into adjacent locking holes. Limiting plates 304 are set on the opposite outer ends of the two rotating columns 306, and an elastic reset component is set between the limiting plate 304 and the pull plate 302. The elastic reset component includes a spring 2 305 set between the pull plate 302 and the limiting plate 304. The two springs 2 305 are respectively sleeved on the corresponding outer arc surfaces of the rotating columns 306, and the upper and lower ends of the pull plate 302 are provided with evenly distributed anti-slip protrusions 307.

[0024] like Figure 1 As shown, a control panel 401 is disposed on the front side of the screening box 102 , and the vibration motor 204 is electrically connected to the control panel 401 .

[0025] like Figure 1 As shown, an observation window 105 is provided in the installation opening opened on the right side of the screening box 102 .

[0026] The personnel control the vibration motor 204 through the control panel 401 to operate and cooperate with the spring 202 to vibrate the screening net 301 on the mounting plate 201, and then the personnel add the refractory material to be screened from the feed port 104 into the inside of the screening box 102, and the refractory material falls onto the vibrating screening net 301. The refractory material larger than the mesh of the screening net 301 will slide out of the screening box 102 from the inclined screening net 301 during the vibration process because it cannot pass through the mesh. The refractory material smaller than the mesh of the screening net 301 passes through the mesh and falls out of the discharge box 103, thereby achieving the screening of the refractory material.

[0027] During the screening process, personnel can observe the screening status of the refractory material in real time through the observation window 105, and can promptly discover the blockage between the refractory material and the screening net 301.

[0028] When the personnel needs to replace the worn screening net 301, the personnel pulls the pull plates 302 on both sides to make the locking column 303 leave the inside of the locking hole, and then rotates the pull plate 302 to make the locking column 303 at the upper end misaligned with the locking hole. At this time, the spring 2 305 is in a compressed state, and then the personnel takes out the worn screening net 301, and then slides the new screening plate into the inside of the mounting plate 201, and then rotates the pull plate 302 to make the locking column 303 at the upper end correspond to the locking hole, and then releases the pull plate 302. At this time, the spring 2 305 rebounds quickly and drives the locking column 303 to insert into the inside of the jack to complete the limit locking of the screening net 301, thereby realizing the rapid replacement of the screening net 301.

[0029] In the process of pulling the pull plate 302 , the anti-slip protrusion 307 can effectively prevent people from slipping.

[0030] According to another embodiment of the present invention, Figure 1 As shown, feet 106 are welded and fixed to the four corners of the lower end of the mounting frame 101, and the contact area between the screening device and the ground is increased by the feet 106 on the mounting frame 101.
