[0040] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are described in detail below in conjunction with the accompanying drawings. It is to be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the present application. It should also be noted that, for ease of description, only some structures related to the present application are shown in the accompanying drawings, rather than all structures. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0041] The terms "including" and "having" and any variations thereof in this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products or devices.

[0042] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0043] like Figure 1 and Figure 2 As shown, a slag ball vibrating screening device corresponding to a preferred embodiment of the utility model includes a containing device 1 and a vibrating device 2.

[0044] The receiving device 1 comprises a cover plate 10, a receiving cavity 11 with an opening at one end, and a screen 12 arranged in the receiving cavity 11. The screen 12 divides the receiving cavity 11 into a first cavity 110 for placing the sample to be tested and a second cavity 111 for containing the filtered object. The filtered object refers to the object that falls into the second cavity 111 through the screen 12. When the vibration device 2 is working, the slag balls will remain on the screen 12, and other small objects will fall under the screen 12. The cover plate 10 is connected to the receiving device 1 and seals the open end of the receiving cavity 11.

[0045] The vibration device 2 is used to drive the receiving device 1 to vibrate, so that the filtered matter in the sample to be tested is screened into the second cavity 111 of the receiving device 1 through the screen 12, and the slag balls are retained on the screen 12.

[0046] According to the requirements of the test standard, the aperture of the screen 12 needs to select a standard mesh corresponding to the mineral wool, and 3 ceramic balls with a diameter of (20±1) mm need to be placed on the screen 12. The frequency of the vibrating device 2 is 23.5 times / s, and the vibration screening time is 15 minutes. After the vibration is completed, the mass of the remaining slag balls can be measured, and then the ratio of the mass of the slag balls to the mass of the sample (i.e., the sample to be tested) can be calculated to obtain the slag ball content.

[0047] The receiving chamber 11 of the receiving device 1 is sealed by the cover plate 10, so that the receiving device 1 becomes a closed device, and the sample to be tested is placed on the screen 12 (that is, placed in the first cavity 110). Driven by the vibration device 2, the receiving device 1 vibrates, and the sample to be tested is screened by the screen 12, and the filtered material falls into the second cavity 111, and the slag balls are retained on the screen 12; under the sealed condition, the slag balls can be prevented from floating into the air or falling to the outside of the container due to vibration, and the mass loss of the slag balls is less, thereby improving the accuracy of the slag ball mass measured subsequently; at the same time, the pollution to the external environment is also reduced.

[0048] like Figure 1 and Figure 2 As shown, in one embodiment, the receiving device 1 includes a filter assembly 13 and a receiving assembly 14, and the filter assembly 13 and the receiving assembly 14 are detachable independent components. The receiving assembly 14 includes a bottom plate 140 and a first annular side wall 141 connected to the bottom plate 140; the filter assembly 13 includes a second annular side wall 130 detachably connected to the first annular side wall 141 and a screen 12 connected to the second annular side wall 130, and the first annular side wall 141 and the second annular side wall 130 can be connected by abutment or fixed by threaded connection. Since the filter assembly 13 is detachable, the filter assembly 13 can be removed and weighed after the test is completed, and the mass of the remaining slag balls minus the mass of the filter assembly 13 itself is the mass of the remaining slag balls. Of course, the slag balls can also be poured out and weighed.

[0049] like Figure 3 and Figure 4 As shown, in another embodiment, the containing device 1 includes a shell 15 with an opening at one end, the shell 15 is a single integrally formed part, the containing cavity 11 is the inner cavity of the shell 15, the sample to be tested is placed on the screen 12 from the open end of the containing device 1, and falls into the second cavity 111 after screening; in order to facilitate the weighing of the mass of the slag balls after screening, the containing device 1 includes a bottom plate 140 and a hole cover 142, the bottom plate 140 is provided with a discharge hole 1400, and the hole cover 142 seals the discharge hole 1400. After the vibration screening is completed, the hole cover 142 can be opened, and the filtered material can be poured out through the discharge hole 1400 and then the weight of the containing device 1 can be weighed. The weighed mass minus the mass of the containing device 1 when the sample to be tested is not placed is the mass of the slag balls.

[0050] It can be understood that the receiving device 1 is configured to include a separately arranged filtering component 13 and a receiving component 14, which is more convenient for measuring the mass of the slag balls than a method including an integrated shell 15, and because the side wall of the shell 15 may have residual filtered material, the separate setting can exclude the mass of the filtered material on the side wall, and the measurement accuracy will also be higher.

[0051] like Figure 5 As shown, in order to facilitate the installation of the screen 12, the second annular side wall 130 includes an annular boss 1300 arranged on the inner surface, and the screen 12 is connected to the annular boss 1300, for example, by gluing. The annular boss 1300 can be arranged in the middle position of the second annular side wall 130, or it can be arranged as shown in FIG. Figure 6 As shown, it is arranged at the lower end of the second annular side wall 130. One of the cover plate 10 and the second annular side wall 130 is provided with a first annular groove 100, and the other is matched in the first annular groove 100 and abuts against the groove bottom surface of the first annular groove 100.

[0052] In one embodiment, if Figure 5 and Figure 7 As shown, the cover plate 10 includes a limiting boss 101 located in the middle and a first annular outer edge 102 surrounding the limiting boss 101, and a first annular groove 100 is formed between the limiting boss 101 and the first annular outer edge 102. When the cover plate 10 and the receiving device 1 are connected, the limiting boss 101 extends into the second annular side wall 130, and the first annular outer edge 102 abuts against the second annular side wall 130. The surface 103 of the first annular outer edge 102 facing the second annular side wall 130 is the bottom surface of the first annular groove 100.

[0053] In another embodiment, if Figures 8 to 10 As shown, the second annular side wall 130 is provided with a first annular groove 100 at the open end facing the cover plate 10, and forms a first annular step 1301 and a third annular outer edge 1305. The cover plate 10 is also provided with a first annular groove 100, and forms a limiting boss 101 and a first annular outer edge 102 surrounding the limiting boss 101. The limiting boss 101 extends into the first annular groove 100 of the second annular side wall 130, and the first annular outer edge 102 abuts against the third annular outer edge 1305.

[0054] The second annular side wall 130 and the first annular side wall 141 can also be relatively fixed by abutting. Specifically, one of the second annular side wall 130 and the first annular side wall 141 is provided with a second annular groove 1410, and the other is connected in the second annular groove 1410 and abuts against the bottom surface of the second annular groove 1410.

[0055] In one embodiment, if Figure 5 and Fig.11 As shown, the second annular side wall 130 includes a limiting protrusion 1303 protruding along the axial direction thereof and a second annular outer edge 1304 surrounding the outside of the limiting protrusion 1303. The limiting protrusion 1303 and the second annular outer edge 1304 cooperate to form a second annular groove 1410 disposed at the opening end facing the first annular side wall 141. When the first annular side wall 141 and the second annular side wall 130 are in contact with each other, the limiting protrusion 1303 extends into the first annular side wall 141, and the second annular outer edge 1304 is in contact with the first annular side wall 141. The surface 1306 of the second annular outer edge 1304 facing the first annular side wall 141 is the bottom surface of the second annular groove 1410.

[0056] In another embodiment, if Figures 8 to 10 As shown, a second annular groove 1410 is provided at the open end of the first annular side wall 141 toward the second annular side wall 130 , and a second annular step 1411 and a fourth annular outer edge 1412 are formed. The second annular side wall 130 is disposed in the second annular groove 1410 , and the second annular side wall 130 abuts against the second annular step 1411 .

[0057] In order to improve the stability of the slag ball vibrating screening device during the vibrating screening process, the slag ball vibrating screening device also includes a fixing device 3, and the cover plate 10 is abutted against the receiving device 1. The fixing device 3 presses the cover plate 10 against the open end of the receiving device 1, thereby ensuring the stability of the slag ball vibrating screening device.

[0058] The number of the fixing devices 3 can be selected according to actual needs, for example, Figure 8 In the embodiment shown, the number of the fixing device 3 is one; Fig.12 and Fig.13 In the embodiment shown, the number of the fixing devices 3 is 2; Figure 3 In the embodiment shown, the number of the fixing devices 3 is 3; Figure 1 In the illustrated embodiment, the number of the fixing devices 3 is 4. The more the number of the fixing devices 3 is, the more it is possible to prevent the slag ball vibrating screen device from loosening during the vibration process.

[0059] Further, such as Figure 12 to Figure 14As shown, the fixing device 3 includes a fixing member 30 and an adjusting member 31. The fixing member 30 includes a first abutting portion 300 abutting against the bottom plate 140, a supporting portion 301 arranged opposite to the cover plate 10, and a connecting portion 302 connected between the first abutting portion 300 and the supporting portion 301; the adjusting member 31 is threadedly connected to the supporting portion 301. Optionally, the adjusting member 31 is a bolt, and the supporting portion 301 is provided with an internal thread corresponding to the adjusting member 31. By adjusting the distance between the adjusting member 31 and the first abutting portion 300, one end of the adjusting member 31 is abutted against the cover plate 10, so that the cover plate 10, the filter assembly 13 and the receiving assembly 14 are clamped and fixed.

[0060] In order to increase the contact area with the cover plate 10 and improve stability, the fixing device 3 includes an abutment member 32 connected to the adjustment member 31. Fig.14 As shown, the end face of the adjusting member 31 is provided with a first threaded hole 310, the abutting member 32 includes a through hole 322, the fixing device 3 includes a bolt 33, and the abutting member 32 is connected and fixed with the adjusting member 31 by the bolt 33. Specifically, the bolt 33 passes through the through hole 322 and is screwed with the adjusting member 31. The abutting member 32 includes a connecting portion 302 connected to the adjusting member 31 and a second abutting portion 321 connected to the connecting portion 302. The cross-sectional size of the connecting portion 302 gradually increases in the direction away from the adjusting member 31. The second abutting portion 321 is in the shape of an annular plate and abuts against the cover plate 10. Since the abutting area between the second abutting portion 321 and the cover plate 10 is larger, the pressure on the cover plate 10 is smaller, so the cover plate 10 is not easy to bend and deform after being subjected to force. Optionally, a soft pad (such as a rubber pad) is also provided on the end face of the second abutting portion 321, which contacts the cover plate 10 through the soft pad, so that the cover plate 10 can be better protected.

[0061] Optionally, the vibration device 2 is disposed on the cover plate 10 or on the receiving device 1. For example, in one embodiment, Figure 1 , Figure 3 and Figure 8 As shown, the vibration device 2 is disposed on the cover plate 10, preferably located at the center of the cover plate 10. In another embodiment, the vibration device 2 is disposed on the first annular side wall 141 or the second annular side wall 130, such as Fig.15 As shown, Fig.15 In the embodiment shown, there are two vibration devices 2, which are symmetrically arranged on the first annular side wall 141. In another embodiment, Fig.12 and Fig.13 As shown, the slag ball vibrating screening device includes a supporting leg 6, and the vibrating device 2 is arranged on the bottom plate 140, preferably located at the center of the bottom plate 140. It can be understood that after the vibrating device 2 vibrates, the receiving device 1 as a whole will be driven to vibrate, so that the filtered material is screened into the second cavity 111.

[0062] like Fig.18 As shown, in order to facilitate the adjustment of the frequency of the vibration device, the slag ball vibrating screen device includes a control module 4 electrically connected to the vibration device 2, and the control module 4 can adjust the vibration frequency of the vibration device 2. Optionally, the vibration device 2 is an eccentric motor, and the control module 4 is a motor driver; the power module 8 is electrically connected to the control module 4 and the vibration device 2, and the power module 8 provides energy for the vibration device 2. The rotation frequency of the eccentric motor can be adjusted through the motor driver, thereby adjusting the frequency of the vibration device, for example, the vibration frequency can be conveniently adjusted to 23.5 times / s.

[0063] like Fig.16 and Fig.17 As shown, the slag ball vibrating screening device includes a vibration isolation device 5, and the vibration isolation device 5 includes a receiving chamber 50 for placing the receiving device 1. A soft material 7 is arranged in the receiving chamber 50. The soft material 7 can be, for example, a sponge. The soft material 7 is filled between the inner bottom surface and the side surface of the vibration isolation device 5 and the slag ball vibrating screening device, and can absorb the vibration energy of the receiving device 1, reduce the transmission of the vibration of the receiving device 1 to the work surface or other placement platform, and is conducive to limiting the position of the slag ball vibrating screening device during vibration and reducing noise. The vibration isolation device 5 can be fixedly connected to the work surface or other placement platform.

[0064] The above are only specific implementations of the present invention, and any improvements made based on the concept of the present invention are considered to be within the protection scope of the present invention.
