Description

Technical Field

[0001] The present application relates to the technical field of waste sand recovery, and in particular to a waste sand iron removal device. Background Art

[0002] Investment casting, also known as lost wax casting, includes processes such as wax pressing, wax repairing, tree assembly, slurry dipping, wax melting, pouring molten metal and post-processing.

[0003] In the related art, after the casting is completed, the broken sand mold is usually broken into pieces, and then ground, and then the ground waste sand is conveyed to the inside of the screening machine through a conveyor belt, and then the screening machine collects and classifies the waste sand according to size, so as to achieve the recycling of the waste sand. However, the waste sand after the sand mold is broken often contains waste iron slag, which may cause wear or impact damage to the screen, screen plate, vibration motor and other parts after entering the screening machine. Therefore, a magnetic iron removal device is usually set at the inlet of the screening machine, although it can effectively remove the waste iron slag in the waste sand.

[0004] The surface of the magnet installed at the inlet of the screening machine needs to be cleaned and maintained regularly. If it is not cleaned in time, the iron removal effect may be reduced due to the accumulated waste iron slag; however, the process of cleaning the surface of the magnet by the staff is rather cumbersome and time-consuming, and the use of the screening machine needs to be stopped during the cleaning process, which will also affect the screening efficiency of the waste sand. There is room for improvement. Utility Model Content

[0005] The purpose of the present application is to provide a waste sand iron removal device to solve the problem in the above-mentioned related technology that the cleaning process of the magnet surface is cumbersome and the cleaning process will affect the waste sand screening efficiency.

[0006] The waste sand iron removal device provided in this application adopts the following technical solution:

[0007] A waste sand iron removal device comprises a conveying component and an iron removal component, the conveying component comprises a support frame, a conveyor belt arranged on the support frame and a driving member, an active roller and a plurality of driven rollers are rotatably arranged on the support frame, and the driving member is used to drive the active roller to rotate; the iron removal component comprises a magnetic suction member arranged in the active roller, and a collecting box located below the support frame, an inclined guide plate is provided on the side of the support frame, the upper end opening of the guide plate is located above the active roller, and the lower end opening of the guide plate is located above the collecting box.

[0008] By adopting the above technical solution, in the process of waste sand being transported to the screening machine through the conveyor belt, the waste iron slag is attracted by the magnetic attraction of the magnetic element. As the conveyor belt rotates, the waste iron slag continues to be adsorbed on the lower side of the conveyor belt. As the distance between the waste iron slag and the magnetic element increases, the magnetic attraction of the magnetic element to the waste iron slag weakens, and the waste iron slag can no longer be adsorbed on the surface of the conveyor belt, and finally falls into the drain plate and slides along the drain plate into the collection box. According to this arrangement, the waste iron slag will not always be adsorbed on the magnetic element, so there is no need to clean the magnetic element regularly, thereby improving the cleaning efficiency of the waste iron slag mixed with the waste sand.

[0009] Optionally, a mounting cavity for placing the magnetic attraction component is provided inside the active roller, and a cover plate for closing the mounting cavity is provided on one side of the active roller.

[0010] By adopting the above technical solution, due to the relative arrangement of the installation cavity and the cover plate, the magnetic attraction component can be pre-installed inside the installation cavity, and then the cover plate can be fixed on the active roller to close the installation cavity, thereby facilitating the installation and fixation of the magnetic attraction component and improving the installation efficiency of the magnetic attraction component.

[0011] Optionally, the magnetic attraction member includes a plurality of magnetic attraction blocks placed in the installation cavity, and the plurality of magnetic attraction blocks are evenly distributed around the axis of the active roller.

[0012] By adopting the above technical solution, since a plurality of magnetic blocks are evenly distributed around the axis of the active roller, the magnetic element can attract the scrap iron slag more evenly, thereby improving the screening effect of the scrap iron slag mixed with the waste sand.

[0013] Optionally, a limiting member for limiting the position of a plurality of magnetic blocks is provided inside the active roller, and the limiting member includes two fixing plates respectively located on both sides of the magnetic blocks, and fixing grooves for inserting the magnetic blocks are provided on the sides of the two fixing plates close to each other.

[0014] By adopting the above technical solution, due to the installation setting of the fixed plate, the multiple magnetic blocks are further limited, reducing the possibility of the multiple magnetic blocks being offset or misaligned due to mutual forces, and improving the installation stability of the multiple magnetic blocks inside the installation cavity.

[0015] Optionally, the active roller is provided with a plurality of positioning blocks on the bottom side of the installation cavity and the cover plate, and the fixing plate is provided with positioning grooves for inserting the positioning blocks.

[0016] By adopting the above technical solution, when the fixed plate is installed inside the installation cavity, the positioning blocks on the cover plate and the active roller are inserted into the positioning grooves on the fixed plate, thereby improving the assembly stability between the fixed plate and the active roller, reducing the possibility of the fixed plate rotating relative to the active roller, and also reducing the possibility of the magnetic suction component loosening in the installation cavity.

[0017] Optionally, a filter cover is provided above the collection box.

[0018] By adopting the above technical solution, due to the installation setting of the filter cover, when the scrap iron slag falls into the collection box along the guide plate, the scrap iron slag of different sizes is classified and screened, and there is no need to install different sizes of scrap iron slag for screening later, which facilitates the subsequent separate treatment of scrap iron slag of different sizes.

[0019] Optionally, handles are provided on two opposite edges of the upper side of the collection box.

[0020] By adopting the above technical solution, since handles are provided on two opposite edges of the upper side of the collection box, it is convenient for subsequent staff to carry the collection box.

[0021] Optionally, the opening size of the guide plate decreases in a direction approaching the collection box.

[0022] By adopting the above technical solution, when the waste iron slag slides on the drainage plate, due to the decreasing setting of the opening size of the drainage plate, effective drainage can be achieved in a limited space, saving space and optimizing the overall layout.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. Due to the installation of the iron removal component, the waste iron slag will not always be adsorbed on the magnetic suction part, so there is no need to clean the magnetic suction part regularly, thereby improving the cleaning efficiency of the waste iron slag mixed with the waste sand.

[0025] 2. Since a number of magnetic blocks are evenly distributed around the axis of the active roller, the magnetic element can attract the scrap iron slag more evenly, thereby improving the screening effect of the scrap iron slag mixed with the waste sand.

[0026] 3. Due to the installation setting of the fixing plate, the plurality of magnetic blocks are further limited, the possibility of the plurality of magnetic blocks being offset or misaligned due to the mutual force is reduced, and the installation stability of the plurality of magnetic blocks inside the installation cavity is improved.

DETAILED DESCRIPTION

[0035] The present application is further described in detail below in conjunction with all the accompanying drawings.

[0036] Example:

[0037] Reference Figure 1 and Figure 2 A waste sand iron removal device comprises a conveying component 1 and an iron removal component 2, wherein the conveying component 1 comprises a support frame 11, a conveyor belt 12 arranged on the support frame 11 and a driving member 13, and the waste sand is transported to a screening machine through the conveyor belt 12; before being transported to the screening machine, the waste iron slag mixed in the waste sand is pre-screened by the iron removal component 2.

[0038] Reference Figure 1 and Figure 2 A driving roller 14 and a plurality of driven rollers 15 are rotatably arranged on the support frame 11, and the conveyor belt 12 is sleeved on the outer periphery of the driving roller 14 and the driven roller 15. The driving member 13 is a coordinated arrangement of a motor and a transmission chain, which is used to drive the driving roller 14 to rotate around its own axis. This is a conventional driving structure and will not be described in detail here.

[0039] Reference Figure 2 and Figure 3The iron removal component 2 includes a magnetic attraction member 21 arranged in the active roller 14, a collecting box 22 located below the support frame 11, a filter cover 23 is arranged above the collecting box 22, and a guide plate 24 is fixedly installed with an inclined setting on the side of the support frame 11, wherein the upper end opening of the guide plate 24 is located above the active roller 14, and the lower end opening of the guide plate 24 is located above the collecting box 22.

[0040] In the process of waste sand being transported to the screening machine through the conveyor belt 12, the waste iron slag is attracted by the magnetic attraction of the magnetic element 21. As the conveyor belt 12 rotates, the waste iron slag continues to be adsorbed on the lower side of the conveyor belt 12. As the distance between the waste iron slag and the magnetic element 21 increases, the magnetic attraction of the magnetic element 21 on the waste iron slag weakens. The waste iron slag can no longer be adsorbed on the surface of the conveyor belt 12, and finally falls into the guide plate 24, and slides along the guide plate 24 into the filter cover 23. The larger waste iron slag is blocked by the filter cover 23, and the smaller waste iron slag finally falls into the collection box 22.

[0041] Reference Figure 2 The opening size of the guide plate 24 decreases gradually in the direction close to the collection box 22. With this arrangement, when the scrap iron slag slides on the guide plate 24, effective drainage can be achieved in a limited space, saving space and optimizing the overall layout. Handles 221 are provided on the two opposite edges of the upper side of the collection box 22 to facilitate subsequent staff to carry the collection box 22.

[0042] Reference Figure 4 and Figure 5 The interior of the active roller 14 is provided with an installation cavity 141 for inserting the magnetic element 21, wherein a cover plate 142 for closing the installation cavity 141 is provided on one side of the active roller 14, and the cover plate 142 is fixedly connected to the active roller 14 by a plurality of bolts; the magnetic element 21 includes eight magnetic blocks 211 inserted into the installation cavity 141, wherein the eight magnetic blocks 211 are evenly distributed around the axis of the active roller 14, so that the magnetic element 21 can attract the scrap iron slag more evenly, thereby improving the screening effect of the scrap iron slag mixed with the waste sand.

[0043] Reference Figure 5 and Figure 6 A limiting member 3 for limiting the position of the eight magnetic blocks 211 is provided inside the active roller 14, wherein the limiting member 3 includes two fixing plates 31 respectively located on both sides of the magnetic blocks 211, and eight fixing grooves 311 for inserting the magnetic blocks 211 are provided on the sides close to each other of the two fixing plates 31; thereby further limiting the position of the eight magnetic blocks 211 is achieved, reducing the possibility of displacement or misalignment of the eight magnetic blocks 211 due to mutual force.

[0044] Reference Figure 5 and Figure 6The active roller 14 is provided with four positioning blocks 1411 on the bottom side of the installation cavity 141 and the cover plate 142. At the same time, a positioning groove 312 for inserting the positioning blocks 1411 is opened on the fixed plate 31, so as to improve the assembly stability between the fixed plate 31 and the active roller 14 and reduce the possibility of loosening of the magnetic attraction component 21 in the installation cavity 141.

[0045] The implementation principle of the embodiment of the present application is:

[0046] In the process of conveying the waste sand to the screening machine through the conveyor belt 12, the waste iron slag mixed in the waste sand is pre-screened by the iron removal component 2, and the cleaned waste sand is normally conveyed to the inside of the screening machine.
