Description

Technical Field

[0001] This application relates to the field of silica sand vibrating screen technology, specifically to a silica sand vibrating screen anti-overflow system. Background Technology

[0002] In the glass manufacturing process, since the silica sand content is about 60% when making float glass, the production of glass cannot be separated from the input of silica sand. Generally, a silica sand vibrating screen is set up at the silica sand feeding site. However, due to the high moisture content of silica sand, it is easy to cause excessive material accumulation on the vibrating screen and screen blockage, which can lead to material overflow from the vibrating screen. In order to remind the staff that the vibrating screen is overflowing, a material overflow switch is installed in the main body of the vibrating screen. When the silica sand touches the material overflow switch, the material overflow switch will activate the alarm connected to it to remind the staff that the vibrating screen is overflowing.

[0003] However, since the overflow switch is located inside the vibrating screen body, it will cause the overflow switch to vibrate with the vibrating screen, which can easily damage the switch contacts, resulting in false alarms or no alarms. This can cause misjudgments in the overflow switch detection, affecting the operator's judgment of whether silica sand is overflowing. If the overflow is not dealt with in time, prolonged overflow will accelerate the wear and tear of the vibrating screen and affect its service life. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a system for preventing material spillage in a silica sand vibrating screen, comprising:

[0005] A storage mechanism, wherein a storage trough is provided inside the storage mechanism;

[0006] The vibrating screen body is disposed in the storage tank. The vibrating screen body is provided with a screening component inside. The screening component is used to screen the silica sand particles. The screening component divides the vibrating screen body into a feeding section and a discharging section.

[0007] The testing mechanism includes a first material guiding device, which is connected to the feed section and is used to discharge the silica sand that is overflowing. A receiving device for receiving the silica sand is provided below the output end of the first material guiding device, and the receiving device is located on one side of the vibrating screen body.

[0008] The control mechanism is connected to the receiving device and to the vibrating screen body. When the receiving device is carrying silica sand, the control mechanism controls the vibrating screen body to stop working to prevent material from overflowing from the feed section.

[0009] According to the technical solution provided in the embodiments of this application, the receiving device includes:

[0010] The support portion has a groove formed thereon;

[0013] According to the technical solution provided in the embodiments of this application, the controlled mechanism includes:

[0014] A first circuit, which is electrically connected to the vibrating screen body;

[0015] The second circuit is electrically connected to the alarm device.

[0016] The control mechanism has a first state and a second state. When it is in the first state, the first circuit is turned on and the second circuit is turned off, and the vibrating screen body works. When it is in the second state, the first circuit is turned off and the second circuit is turned on, the vibrating screen body stops working, and the alarm device sounds an alarm.

[0017] According to the technical solution provided in the embodiments of this application, the control mechanism further includes:

[0018] The controller body has a first cavity inside, and a first contact group and a second contact group are provided inside the controller body. The first contact group and the second contact group are distributed along a first direction, which is parallel to the bottom wall of the storage tank. The first contact group is arranged on the first circuit. When the first contact group is turned on, the first circuit is turned on. When the second contact group is turned on, the second circuit is turned on.

[0019] A transmission assembly for switching between the first state and the second state.

[0020] According to the technical solution provided in the embodiments of this application, the transmission component includes:

[0021] A conductive element, which is perpendicular to the first direction and movably disposed between the first contact group and the second contact group, is movable in the first direction to abut against the first contact group or against the second contact group;

[0022] A first connecting rod is movably disposed within the first cavity. The first connecting rod is fixedly connected to the conductive member and parallel to the first direction. One end of the first connecting rod is connected to a first elastic member, and the end of the first elastic member away from the first connecting rod is fixedly connected to the inner wall of the controller body.

[0023] The second link is fixedly connected to the end of the first link away from the first elastic member. The second link is parallel to the first direction and moves through the side wall of the controller body.

[0024] The third link is hinged to the second link at one end outside the controller body. The end of the third link away from the second link has a second abutment portion, which abuts against the bottom of the first abutment portion. A second elastic member is connected to the side of the second abutment portion away from the first abutment portion, and the end of the second elastic member away from the second abutment portion is fixedly connected to the bottom wall of the storage tank.

[0025] According to the technical solution provided in the embodiments of this application, a vibration motor is fixedly connected to the vibrating screen body.

[0026] According to the technical solution provided in the embodiments of this application, the top wall of the vibrating screen body is provided with an inlet communicating with the feeding section, and the bottom wall of the vibrating screen body is provided with an outlet communicating with the discharging section.

[0027] According to the technical solution provided in the embodiments of this application, the screening component includes a screen, which is inclinedly disposed in the vibrating screen body. A second material guiding device communicating with the feed section is also provided on the side wall of the vibrating screen body. The second material guiding device is used to guide the silica sand particles flowing down along the screen.

[0028] According to the technical solution provided in the embodiments of this application, a plurality of shock absorbers perpendicular to the bottom wall of the vibrating screen body are fixedly connected, and a support device is fixedly connected to the side of the shock absorber away from the vibrating screen body. The side of the support device away from the shock absorber is fixedly connected to the bottom wall of the storage tank.

[0029] The beneficial effects are:

[0030] Since the vibrating screen body is located inside the storage tank, and a screening component is provided inside the vibrating screen body, the screening component divides the vibrating screen body into an inlet section and an outlet section. Therefore, when it is necessary to screen silica sand particles, silica sand is put into the inlet section, the silica sand particles are screened by the screening component, and the screened particles enter the outlet section to complete the screening of silica sand particles.

[0031] Because the detection mechanism includes a first material guiding device connected to the feed section, and a receiving device for receiving silica sand is provided below the output end of the first material guiding device, the receiving device is located on one side of the vibrating screen body, and is connected to the control mechanism. The control mechanism is also connected to the vibrating screen body. Therefore, when the vibrating screen body experiences material overflow, the overflowing silica sand flows out along the first material guiding device and onto the receiving device. After the control mechanism senses that the receiving device is carrying silica sand, it controls the vibrating screen body to stop working. This silica sand vibrating screen anti-overflow system can accurately determine the overflow situation when the vibrating screen body experiences material overflow and can promptly shut down the vibrating screen body, reducing wear and tear on the vibrating screen body and extending its service life.

[0043] Specifically, the feed section 22 is located above the discharge section 23.

[0044] Specifically, the sieving component 21 is used to screen out silica sand particles of a preset volume.

[0045] Furthermore, when it is necessary to screen the silica sand particles, the silica sand is fed into the feed section 22, and the silica sand particles are screened by the screening component 21. Silica sand particles that meet the preset volume are screened by the screening component 21 and enter the discharge section 23 to complete the screening of silica sand particles.

Once the control mechanism 4 senses that the receiving device 32 is carrying silica sand, it controls the vibrating screen body 2 to stop working. This silica sand vibrating screen anti-overflow system can accurately determine the overflow situation when it occurs and promptly shut down the vibrating screen body 2, reducing wear and tear and extending its service life.

[0063] Specifically, when the vibrating screen body 2 screens silica sand particles, the control mechanism 4 controls the first circuit to be turned on so that the vibrating screen body 2 can work. When the vibrating screen body 2 experiences material overflow, the control mechanism 4 controls the first circuit to be turned off and the second circuit to be turned on, so that the vibrating screen body 2 stops working. The alarm device 5 issues an alarm, which can promptly and accurately remind the staff that the vibrating screen has experienced material overflow and automatically shuts down the operation of the vibrating screen body 2 to prevent prolonged material overflow from causing damage to the vibrating screen body 2.

[0064] In a preferred embodiment, the control mechanism 4 further includes:

[0076] Specifically, when the vibrating screen body 2 is working, the conductive element 6 and the first contact group 42 abut against each other, so that the first contact and the second contact are connected, thereby making the first circuit connected.

[0077] Furthermore, when the receiving device 32 carries silica sand, the first abutting part 321 moves slightly downward with the supporting part 322, the second elastic member 82 is compressed, and the third connecting rod 73 rotates. The third connecting rod 73 drives the second connecting rod 72 and the first connecting rod 71 to move in a first direction toward the receiving device 32.

[0078] Furthermore, when the worker removes the silica sand from the receiving device 32, the first elastic element 81 and the second elastic element 82 reset, thereby driving the third connecting rod 73 to rotate.
