Description

Technical Field

[0001] The utility model relates to the technical field of screening devices, and more specifically, to a hoisting dry powder screening device. Background Art

[0002] Dry powder screening equipment is a screening machine designed specifically for dry powder materials, mainly used in fields such as construction and chemical industry. These devices utilize vibration technology and are often equipped with vibration motors as the power source to drive the screen surface to vibrate at high frequency, achieving the separation, filtration, impurity removal, and grading of dry powder materials according to particle size.

[0003] The current dry powder screening equipment still has the following problems:

[0004] 1. Dry powder screening equipment is mainly used for screening powdery materials. Since the materials are powdery, dust will be stirred up during the screening process. At the same time, the screening device is in a vibrating state during screening, so it will not be directly connected to the feeding pipe at the top. This will cause the stirred-up dust to escape from the connection between the vibrating screen and the feeding pipe, which will not only cause waste of materials but also affect the nearby environment.

[0005] 2. The materials after being classified by the dry powder screening equipment will be directly bagged and stored. However, since the dry powder screening equipment is placed on the ground, the materials after classification will fall into the storage equipment on the ground. At this time, the operating space will become smaller, and workers need to bend down to bag the materials, which will increase the labor intensity of the workers. Moreover, when the dry powder screening equipment is placed on the ground, it will also occupy the ground space, resulting in a smaller space for workers to move.

[0006] Therefore, it is necessary to propose a hoisting dry powder screening device to solve the above problems. Summary of the Utility Model

Detailed Description of the Embodiment

[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0030] Please refer to Figures 1-4, A dry powder screening equipment for hoisting, including a hoisting frame 101, a pneumatic valve 102, a hook 103, a dry powder sieve 104, and a dust removal hood 105. The hoisting frame 101 is suspended on other equipment or a building structure through the hook 103, preferably at the bottom of the equipment feeding port, so that after the material is affected by other equipment, it can directly enter the dry powder sieve 104 for classification and screening. The dry powder sieve 104 and the dust removal hood 105 are fixed inside the hoisting frame 101, and one discharge port of the dry powder sieve 104 extends into the dust removal hood 105. The dust removal hood 105 is also known as a dust suction hood or a gas collection hood, which is a key component in the dust removal system. It is mainly used to capture and collect dust, soot, and other harmful particles generated during the working process to prevent them from spreading into the working environment, keep the air clean, protect the health of workers, and meet environmental protection standards. This is a mature equipment and will not be elaborated too much here. Another discharge port of the dry powder sieve 104 is connected to a discharge pipeline 106. The material that does not pass through the sieve mesh of the dry powder sieve 104 will be discharged from the discharge pipeline 106. A bracket is provided at the bottom of the discharge pipeline 106 to fix the discharge pipeline 106 to the bottom plate 118. One end of the hook 103 is connected to the hoisting frame 101, and the other end is fixed at the suspension point. The pneumatic valve 102 is connected to the top of the hoisting frame 101, and the output end is connected to a feed pipeline 121. The top of the feed pipeline 121 is connected to the discharge port of the feeding equipment, and the bottom extends into the dry powder sieve 104. The output end of the pneumatic valve 102 is installed on the feed pipeline 121. The feed pipeline 121 is connected to the bottom of the feeding equipment, and the bottom of the feed pipeline 121 extends into the dry powder sieve 104;

[0031] Specifically, the dust removal hood 105 can be connected to a conveying pipeline to guide the screened material to a feed bag for direct bagging operation.

[0032] Reference Figure 1 and Figure 2 , A top cover 107 is provided on the top of the dry powder sieve 104. The top of the dry powder sieve 104 is the feeding port. The bottom of the dry powder sieve 104 is fixed to the bottom plate 118 through a shock absorption device. A circular hole 120 corresponding to the position of the vibration motor is provided on the upper surface of the bottom plate 118 to accommodate the vibration motor and at the same time has the effect of reducing the overall height of the equipment to achieve the effect of saving space. A circular feed ring 108 is connected to the top of the top cover 107;

[0033] Reference Figure 2 and Figure 3 , A fixing ring 109 is connected to the outer wall of the feed pipeline 121. A sealing plate 110 is slidably connected up and down at the bottom of the feed pipeline 121. The sealing plate 110 covers the top of the feed ring 108 under the push of a spring 111;

[0034] Specifically, reference Figure 2 and Figure 3, the sealing plate 110 can cover the feeding ring 108. When the dry powder sieve 104 performs vibrating screening, the dust stirred up by the material will not leak from the connection between the feeding ring 108 and the feeding pipe 121. When the dry powder sieve 104 vibrates, the reset ring 114 deforms by stretching or compressing to cope with the displacement generated during the vibration of the dry powder sieve 104. A spring 111 is connected between the sealing plate 110 and the fixed ring 109, and the spring 111 pushes the sealing plate 110 to cover the feeding ring 108;

[0035] Reference Figure 3 and Figure 4 , a first connecting block 112 is connected to the bottom of the sealing plate 110. When the dry powder sieve 104 is working, it will be in a state of vibrating displacement, while the feeding pipe 121 is fixed. At this time, the distance between the feeding pipe 121 and the feeding ring 108 will change. The deformation of the reset ring 114 is used to cope with the change in displacement. The smaller the gap between the feeding pipe 121 and the feeding ring 108 on one side, the greater the deformation of the reset ring 114 and the greater the reaction force, which has the effect of restricting the feeding ring 108 to keep it centered. A second connecting block 113 is connected to the inner ring surface of the feeding ring 108, and a reset ring 114 is connected between the first connecting block 112 and the second connecting block 113. The reset ring 114 is oval, and the oval shape can be stretched and compressed to the greatest extent to cope with the change in distance;

[0036] Reference Figure 3 and Figure 4 , a ring-shaped brush 115 is connected to the top of the inner ring surface of the feeding ring 108. When the feeding ring 108 moves under the bottom of the sealing plate 110, it will drive the ring-shaped brush 115 to clean the bottom of the sealing plate 110 to clean the dust attached to it. The top of the ring-shaped brush 115 is in contact with the lower surface of the sealing plate 110.

[0037] Specifically, refer to Figure 2 , a material distribution cone 116 is connected to the bottom inner wall of the feeding pipe 121. The material distribution cone 116 is conical. When materials pass through, they will be dispersed in all directions to increase the distribution of the materials, making the screening of the materials during vibration more uniform.

[0038] Specifically, refer to Figure 1 , the lifting frame 101 includes a top plate 117, a bottom plate 118 and a support frame 119. A lifting ring is provided at the top of the top plate 117 for connecting with the lifting hook 103, and the support frame 119 is connected between the top plate 117 and the bottom plate 118.

[0039] Specifically, refer to Figure 1, a shock absorption assembly and a vibration motor are connected to the bottom of the dry powder sieve 104. The bottom end of the shock absorption assembly is connected to the bottom plate 118. The vibration motor is used as the power source, preferably a vertical vibration motor. A circular hole 120 surrounding the vibration motor is formed in the bottom plate 118, and the size of the circular hole 120 is larger than that of the vibration motor.

[0040] Specifically, referring to Figure 1 , the pneumatic valve 102 is connected to the top plate 117. The pneumatic valve 102 controls the on-off of the material in the feeding pipeline 121. The discharging pipeline 106 and the dust removal cover 105 are connected to the bottom plate 118.

[0041] In this embodiment, the lifting frame 101 is suspended at the bottom of the feeding device through the hook 103. The discharging port at the bottom of the feeding device is connected with a feeding pipeline 121. The feeding pipeline 121 extends into the dry powder sieve 104. The pneumatic valve 102 is fixed on the top plate 117, and the output end is located on the feeding pipeline 121. The dry powder sieve 104, the dust removal cover 105 and the discharging pipeline 106 are installed on the lifting frame 101. The discharging port at the top of the dry powder sieve 104 is connected to the discharging pipeline 106, and the discharging port at the bottom is connected to the dust removal cover 105.

[0042] When screening materials, start the vibration motor at the bottom of the dry powder sieve 104. At this time, the dry powder sieve 104 generates vibration, and open the pneumatic valve 102. At this time, the materials will pass through the feeding pipeline 121 and enter the dry powder sieve 104. When the materials pass through the material distribution cone 116, they will be guided by the inclined surface on the material distribution cone 116, so as to move dispersedly around, so that the materials can be evenly sprinkled on the sieve mesh in the dry powder sieve 104. The materials that have not passed through the sieve mesh will be discharged from the discharging pipeline 106, and the materials that have passed through the sieve mesh will enter the dust removal cover 105. The dust removal cover 105 is used for screening the entering materials, so that the solid materials are discharged from the bottom, while the gas will be discharged from the outlet at the top.

[0043] After suspending the dry powder sieve 104 through the lifting frame 101, the floor area can be saved to expand the activity area of the operator. At the same time, a pipeline can be connected to the bottom of the dust removal cover 105 to guide the screened materials to the material bag for bagging, thus increasing the operable space of the operator.

[0044] The above-mentioned implementation manners are only the preferred implementation manners of the present invention, and cannot be used to limit the protection scope of the present invention. Any non-substantial changes and substitutions made by those skilled in the art based on the present invention belong to the protection scope required by the present invention.
