Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, and more specifically to a double-channel dumping and discharging quality inspection vibrating screen. Background Art

[0002] A vibrating screen is a filtering mechanical separation device that uses the reciprocating vibration generated by the excitation of a vibrator. It is usually composed of a screen and a vibrator. A grain vibrating screen is a mechanical device specifically used for screening grains. It uses vibration force to move the material on the screen surface, thereby screening grains of different particle sizes. A grain vibrating screen uses the vibration force generated by a vibrating motor or exciter to vibrate the screen box and screen. When the material enters the screen box from the feed inlet, the material will jump on the screen surface under the action of the vibration force. Larger particles will roll and jump along the screen surface, gradually moving toward the discharge port of the screen box; while smaller particles will be screened out through the pores of the screen.

[0003] The screening capacity of the vibrating screen is limited by the size of the mesh holes. At present, the mesh holes of the screen are usually divided into standard sizes and non-standard sizes, and the non-standard sizes vary depending on the use environment. This size limitation requires the use of screens with different mesh sizes when screening materials with large differences in particle size, and even requires the replacement of the entire vibrating screen, which increases the complexity and cost of operation. Replacing the screen is a tedious and time-consuming task, especially when operating continuously on the production line. Frequent replacement of the screen will seriously affect production efficiency and production continuity. In addition, screens with different mesh sizes may also have problems such as improper installation and poor sealing during the replacement process, further increasing the difficulty of use and failure rate.

[0004] The above shortcomings need to be improved. Summary of the invention

[0026] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] like Figure 1 As shown, a dual-channel dumping discharging quality inspection vibrating screen described in one embodiment of the utility model includes a sieve plate 1, a sieve 101 is arranged in the sieve plate 1, a partition 102 is arranged on the sieve 101, and the partition 102 is used to divide the sieve plate 1 into multiple screening areas. The sieve hole size of the sieve 101 in each screening area is different, and each screening area is used to screen materials with different particle sizes.

[0029] During operation, the discharge port of the material to be screened is aligned with the corresponding screening area, and the material enters the screen plate 1. The vibration force generated by the vibration motor or the exciter is used to vibrate the screen plate 1, the screen 101 starts to vibrate, and the material jumps on the screen 101. Larger particles will roll and jump along the screen surface, while smaller particles will be screened out through the sieve holes of the screen 101. Finally, the screened materials will be poured out through their respective discharge ports, completing the entire screening process. When it is necessary to screen materials of other particle sizes, the discharge port can be aligned with the corresponding screening area, and the material can be screened by falling into the area without using other equipment or replacing the screen 101. For example, in a grain inspection machine, when testing the quality of grain, it is necessary to remove impurities from grains of different particle sizes such as wheat, corn, and rice. Impurities can be removed by throwing different grains into the corresponding screening area.

[0030] In this embodiment, by setting a plurality of screening areas and making the mesh size of the screen 101 in each screening area different, the screening of materials with large differences in particle size can be achieved, and there is no need to frequently replace the screen 101, which greatly improves the screening efficiency. Secondly, there is no need to frequently replace the screen 101, which reduces the maintenance cost of the equipment and reduces the downtime, thereby ensuring the continuity of production. At the same time, the screening area is selected according to the particle size of the material, and the screening accuracy is high, which can ensure that the material is accurately screened according to the particle size. In addition, in actual application, the vibrating screen can also be used for material screening in the chemical industry, building materials and other industries.

[0031] like Figure 2 As shown, in a preferred embodiment, the screen plate 1 includes two screening layers 104 and a waste receiving layer 105 arranged below the screening layer 104, the screen 101 is arranged at the bottom of the screening layer 104, the screen hole size of the upper screen 101 is larger than the material particle size, the screen hole size of the lower screen 101 is smaller than the material particle size, and a material receiving tray 106 is arranged at the bottom of the waste receiving layer 105.

[0032] When wheat and other materials are put into the upper screening layer 104 of the sieve plate 1, since the mesh size of the upper screen 101 is larger than the grain size of wheat but smaller than the grain size of large-sized impurities such as wheat straw, the impurities such as wheat straw will be retained on the upper screen 101, while the wheat will continue to fall to the lower screening layer 104. In the lower screening layer 104, since the mesh size of the screen 101 is smaller than the grain size of wheat, the wheat will be retained, while small particles of impurities such as dust will pass through the screen 101 and fall into the waste receiving layer 105 below. A material receiving tray 106 is provided at the bottom of the waste receiving layer 105 to collect these fine impurities.

[0033] By using two layers of screens 101 together, the impurities of different particle sizes in the material can be accurately separated, and large-sized impurities such as straw and small particle impurities such as dust can be effectively removed, ensuring the purity of the wheat. In addition, the waste receiving layer 105 allows fine impurities to be collected in a centralized manner for subsequent processing. The entire screening process does not require the replacement of the screen 101, which reduces maintenance costs and improves the stability and service life of the equipment. The screening process is continuous and efficient, which reduces downtime and improves production efficiency.

[0034] like Figure 2 As shown, in a preferred embodiment, each layer of the sieve plate 1 is provided with a discharge port, and the discharge port is provided with a discharge guide groove 107, and each discharge guide groove 107 is arranged on the first side of the sieve plate 1, and the baffle plate on the first side of each layer of the sieve plate 1 is inclined toward the side away from the screening area, and the partition plate 102 is provided with a guide plate 103 at one end close to the discharge guide groove 107, and the guide plate 103 is inclined toward the side away from the screening area.

[0035] After being screened by the screen 101, the material enters the discharge port of each layer of the sieve plate 1 respectively. Since a discharge guide groove 107 is provided at the discharge port, the side opposite to the discharge port of the sieve plate 1 is lifted, and the material flows to the guide groove and smoothly slides out of the sieve plate 1 under the action of gravity and the inclined baffle. The baffle on the first side of each layer of the sieve plate 1 is inclined toward the side away from the screening area to ensure that the material can flow smoothly into the guide groove. At the same time, a guide plate 103 is provided at one end of the partition 102 close to the discharge guide groove 107. These guide plates 103 are also inclined toward the side away from the screening area, which helps to guide the material to flow into the corresponding guide groove more accurately.

[0036] In this embodiment, by providing the discharge guide groove 107, the material can flow out of the sieve plate 1 along a predetermined path, thereby improving the orderliness and efficiency of material collection. Secondly, the inclined baffle and guide plate 103 allow the material to flow naturally under the action of gravity, reducing the blockage and retention of the material, further improving the effect of material collection, not only simplifying the material collection operation process, reducing the labor intensity, but also improving the overall operation efficiency of the equipment. At the same time, orderly material collection also helps the smooth progress of subsequent processing work and improves the efficiency of the entire production process.

[0037] like Figure 2 As shown, in a preferred embodiment, a hopper 110 is provided at the bottom of the discharge guide groove 107 at one end away from the discharge port, the discharge guide groove 107 of the upper screening layer 104 and the waste receiving layer 105 is a waste discharge groove 108, and the discharge guide groove 107 of the lower screening layer 104 is a clean material groove 109, and the waste discharge groove 108 and the clean material groove 109 are in different directions.

[0038] After the material is screened by the screen 101, it will enter the discharge guide groove 107 of each layer of the screen plate 1 respectively. The discharge guide groove 107 is provided with a hopper 110 at the bottom of the end away from the discharge port to collect the material. In particular, the discharge guide groove 107 of the upper screening layer 104 and the waste receiving layer 105 is designed as a waste discharge groove 108, which is used to collect the screened waste, such as large-sized impurities such as straw and small-particle impurities such as dust; the discharge guide groove 107 of the lower screening layer 104 is used as a clean material groove 109, which is specially used to collect the screened pure materials, such as wheat. The waste discharge groove 108 and the clean material groove 109 have different directions, so that the waste and pure materials can be collected in different containers respectively, which is convenient for subsequent classification and processing. During the whole process, the material flows in an orderly manner under the guidance of the discharge guide groove 107 and the hopper 110, realizing efficient material separation and collection.

[0039] In this embodiment, the hopper 110 allows the material to flow directly into the container, reducing the loss and waste of the material during the screening process. Secondly, the distinction between the waste discharge trough 108 and the clean material trough 109 allows the waste material and the pure material to be collected separately, improving the accuracy and efficiency of material classification, simplifying the operation process of material collection and processing, reducing the labor intensity, and improving the overall operation efficiency of the equipment.

[0040] like Figure 2 As shown, in a preferred embodiment, a vibration mechanism 2 is provided below the sieve plate 1 , and an elastic connecting member 3 is connected between the vibration mechanism 2 and the sieve plate 1 .

[0041] The vibration mechanism 2 includes a base 201 , on which a motor 205 is disposed, on which an eccentric connecting block 206 is disposed on the output shaft of the motor 205 , on which a connecting rod 207 is disposed, and the connecting rod 207 is connected to the sieve plate 1 .

[0042] The elastic connecting member 3 includes a plurality of springs, the top of the spring is connected to the bottom of the sieve plate 1 , and the bottom of the spring is connected to the base 201 .

[0043] When the motor 205 is started, the output shaft of the motor 205 drives the eccentric connecting block 206 to rotate. Due to the design of the eccentric connecting block 206, the connecting rod 207 rotates around the center line of the output shaft of the motor 205. The rotation of the connecting rod 207 causes the sieve plate 1 to vibrate back and forth. A plurality of springs are connected between the sieve plate 1 and the vibration mechanism 2 as elastic connectors 3. On the one hand, the springs stably connect the sieve plate 1 and the base 201 to prevent the sieve plate 1 from tipping over during the vibration process. On the other hand, the sieve plate 1 can rock relative to the base 201 to ensure the vibration effect. On the other hand, the springs have a good vibration isolation effect and can reduce the vibration of the base 201. Supported by the springs and driven by the vibration mechanism 2, the sieve plate 1 vibrates periodically, so that the material on the screen 101 moves in a jumping manner to achieve the purpose of screening.

[0044] In this embodiment, the combination of the eccentric connecting block 206 and the connecting rod 207 of the vibration mechanism 2 provides a stable and powerful vibration source for the sieve plate 1, ensuring the continuity and efficiency of the screening process. In addition, the use of the spring in the elastic connector 3 allows the sieve plate 1 to have better balance during the vibration process, making the screening process more stable and ensuring the screening effect. The stable connection of the spring ensures the stability and safety of the sieve plate 1 during high-speed vibration, and effectively prevents the sieve plate 1 from overturning. The elasticity of the spring allows the sieve plate 1 to shake moderately relative to the base 201, enhancing the fluidity of the material in the sieve plate 1 and improving the screening efficiency.

[0045] like Figure 2As shown, in a preferred embodiment, a dumping mechanism 4 is provided on the side of the base 201 away from the discharge port, and the dumping mechanism 4 lifts the side of the sieve plate 1 away from the discharge port for dumping materials.

[0046] The base 201 includes a fixed seat 202 and a movable seat 203, which are rotatably connected at a first side. The tipping mechanism 4 includes a telescopic rod, whose fixed end is rotatably connected to the fixed seat 202 and whose movable end is rotatably connected to the movable seat 203.

[0047] When the screening process is completed, the material in the sieve plate 1 needs to be dumped. During the dumping process, the telescopic rod is extended, and through the transmission of force, the movable seat 203 is rotated relative to the fixed seat 202, thereby lifting the side of the sieve plate 1 away from the discharge port. As the movable seat 203 rotates, the sieve plate 1 tilts, and the material slides along the surface of the sieve plate 1 under the action of gravity, and finally pours out through the discharge port. During the dumping process, the vibration mechanism 2 can be started at the same time to quickly dump the material on the sieve plate 1. After the dumping is completed, the telescopic rod is retracted, the movable seat 203 is reset, and the sieve plate 1 returns to the horizontal state.

[0048] In this embodiment, the inclination angle of the sieve plate 1 can be precisely controlled by the telescopic action of the telescopic rod, thereby ensuring that the material can be poured out smoothly and quickly, thereby improving the efficiency of material processing. In addition, due to the rotational connection between the fixed seat 202 and the movable seat 203, the pouring process is smoother, reducing the loss and splashing of the material during the pouring process. In addition, the pouring mechanism 4 improves the efficiency and convenience of material processing and improves the automation level of the entire equipment.

[0049] like Figure 2 As shown, in a preferred embodiment, a counterweight block 204 is disposed on the movable seat 203, and the counterweight block 204 and the movable seat 203 are connected by fasteners.

[0050] When the sieve plate 1 is vibrating and screening under the action of the vibration mechanism 2, the sieve plate 1 and the base 201 may be affected by instability due to the uneven distribution of materials and the force generated by vibration. In order to overcome this instability, a counterweight block 204 is set on the movable seat 203 and is firmly connected to the movable seat 203 through fasteners. The counterweight block 204 can balance the various moments generated by the sieve plate 1 during the vibration process, ensuring that the sieve plate 1 can remain relatively stable during vibration and prevent overturning or shaking. A stable working environment helps to improve screening efficiency and reduce the risk of equipment damage.

[0051] In this embodiment, the counterweight 204 improves the stability of the base 201, so that the sieve plate 1 can remain relatively stable during vibration, preventing the occurrence of overturning or shaking. Secondly, the setting of the counterweight 204 can also reduce the impact and damage of vibration on other parts of the equipment, thereby extending the service life of the equipment. In addition, by adjusting the position and number of the counterweight 204, the vibration state of the sieve plate 1 can be further optimized to adapt to different materials and screening requirements, thereby improving the adaptability and flexibility of the equipment.

[0052] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
