Description

Technical Field

[0001] The utility model relates to the technical field of industrial powder lifting, in particular to a powder lifting device. Background Art

[0002] In the process of industrial production, when there is powder in the processing flow, a powder lifting device is required to lift and transport this type of raw materials. The powder elevator is a fixed mechanical conveying equipment, which is mainly suitable for the continuous lifting of powder, granular and small pieces of materials.

[0003] According to a powder elevator disclosed in Chinese patent announcement No. CN220244552U, the patent improves the filtering effect by setting an inclined filter screen and making it vibrate driven by a vibration motor, so that impurities can be separated, so that the filtered powder can be lifted and transported normally, which is relatively practical. However, the patent still has certain shortcomings in actual use. Since the feeding screw and the inclined filter screen are arranged inside the same feed hopper, the powder entering the interior through the top of the feed hopper will fall in an accumulated manner due to the vibration of the inclined filter screen, and the accumulated powder is not easy to pass through the filtration of the inclined filter screen. Only the powder at the bottom can complete the filtering work, which will cause a large amount of normal powder to be discharged through the discharge pipe. If the powder is not poured directly into the interior of the feed hopper, the staff is required to continuously and in small amounts to add the powder, which is extremely inconvenient for the staff. In this regard, the present application provides a powder lifting device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4The utility model provides a technical solution: a powder lifting device, comprising a lifting chassis 1, a lifting assembly 200 for lifting powder is installed on the top of the lifting chassis 1, a lifting block 3 is fixed on the top of the lifting chassis 1, an impurity collecting box 4 for collecting impurities is fixed on the top of the lifting block 3, and a linear conveying assembly 500 for smoothly conveying powder is installed on the top of the lifting block 3; through the coordinated use of the lifting assembly 200 on the top of the lifting chassis 1 and the linear conveying assembly 500, the impurity separation and lifting of the powder can be conveniently and effectively carried out, so that the powder can be stably and smoothly transported to the inside of the structure for impurity separation, so that the powder will not be separated in a piled state, which greatly reduces the possibility of normal powder being discharged by mistake, so that the lifting work of the powder can be carried out normally and effectively, and the workload of the staff is saved, thereby effectively improving the practicality of the powder lifting device.

[0025] In this embodiment, the linear conveying assembly 500 is a structure for conveying powder materials smoothly and evenly so that impurities can be separated efficiently and with high quality.

[0026] like Figure 2 , Figure 3 and Figure 4 As shown, the linear conveying assembly 500 includes four lifting rods 501 fixed to the top of the lifting block 3, a loading box 502 fixed between the tops of the four lifting rods 501, a linear cylinder 503 fixed to the bottom of the loading box 502, a second driving mechanism 504 fixedly installed on the right side of the linear cylinder 503, a second driving rod 505 rotatably connected to the inner side of the linear cylinder 503 through a bearing, a second spiral blade 506 fixed to the outer side of the second driving rod 505, a feeding pipe 507 located below the linear cylinder 503, and a feeding box 508. 8. An impurity removal pipe 509 fixed to the right side of the feed box 508, a conveying pipe 510 fixed to the bottom of the linear cylinder 503 and passing through the top of the feed box 508, a telescopic rod 511 fixedly installed on the inner top wall of the feed box 508, a fixing plate 512 fixed to the outer side of the output shaft of the telescopic rod 511, an elastic member 513 fixed between the top of the fixing plate 512 and the inner top wall of the feed box 508, a filter screen plate 514 fixed to the end of the output shaft of the telescopic rod 511, and a vibration motor 515 fixedly installed at the bottom of the filter screen plate 514.

[0027] It should be noted that the second driving mechanism 504 can be a small servo motor. The output shaft of the second driving mechanism 504 passes through the right side of the linear cylinder 503 and is fixedly connected to the right end of the second driving rod 505, so that the second driving mechanism 504 can drive the second driving rod 505 to rotate, and the end of the impurity exhaust pipe 509 extends to the top of the impurity collection box 4, so that the impurities discharged from the impurity exhaust pipe 509 can be collected by the impurity collection box 4.

[0028] In addition, the bottom end of the conveying pipe 510 is located above the filter screen 514, so that the powder entering the feed box 508 through the conveying pipe 510 can fall on the top of the filter screen 514, and the conveying pipe 510 will not affect the normal vibration of the filter screen 514. The elastic member 513 is located on the outside of the telescopic rod 511, so that the elastic member 513 can be smoothly stretched or compressed by the fixing plate 512. The elastic member 513 is a spring. The telescopic rod 511 consists of an outer tube and an inner rod slidably connected to the inner side of the outer tube, and a limit member is provided at the end of the inner rod, which can limit the inner rod through the limit member, thereby preventing the inner rod from detaching from the inner side of the outer tube. It is a conventional rod-shaped telescopic structure.

[0029] At the same time, the right side of the filter screen plate 514 is located inside the impurity exhaust pipe 509, and the interior of the impurity exhaust pipe 509 allows the filter screen plate 514 to move up and down. The filter screen plate 514 is tilted toward the side close to the impurity exhaust pipe 509, and the tilt angle is not greater than ten degrees. Specifically, the tilt angle is five degrees, so that the filter screen plate 514 can be driven by the vibration motor 515 to vibrate up and down. At the same time, under the effect of the tilt, the powder at the top of the filter screen plate 514 can enter the interior of the impurity exhaust pipe 509 and then be discharged.

[0030] In this embodiment, the lifting assembly 200 is a structure for lifting and conveying powder.

[0031] like Figure 1 As shown, the lifting assembly 200 includes two fixed rods 201 fixed to the top of the lifting chassis 1, a lifting cylinder 202 fixed between the top ends of the two fixed rods 201, a discharge pipe 203 fixed to the top outside of the lifting cylinder 202, a first driving mechanism 204 fixedly installed on the top end of the lifting cylinder 202, a first driving rod 205 rotatably connected to the inner side of the lifting cylinder 202 through a bearing, and a first spiral blade 206 fixedly connected to the outside of the first driving rod 205.

[0032] It should be noted that the first drive mechanism 204 can be a servo motor, and the output shaft of the first drive mechanism 204 passes through the top of the lifting cylinder 202 and is fixedly connected to the top of the first drive rod 205, so that the first drive mechanism 204 can drive the first drive rod 205 to rotate.

[0033] In addition, the bottom end of the feed pipe 507 passes through the top of the lifting cylinder 202, the outer side of the feed pipe 507 is fixedly connected to the outer side of the lifting cylinder 202, the interior of the feed pipe 507 is connected to the interior of the lifting cylinder 202, and the feed box 508 is fixed to the top of the feed pipe 507, so that the powder inside the feed box 508 can enter the interior of the lifting cylinder 202 through the feed pipe 507.

[0034] The working principle of the above embodiment is:

[0035] When the powder is lifted, a large amount of powder is poured into the charging box 502 at one time by mechanical or manual pouring, the second driving mechanism 504 is started, the second driving rod 505 is driven to rotate, and the powder is moved inside the linear cylinder 503 under the pushing action of the second spiral blade 506, and enters the inside of the feed box 508 through the conveying pipe 510, so that the powder falls to the top of the filter screen plate 514, and the vibration motor 515 is started to drive the filter screen plate 514 to vibrate up and down under the connection action of the telescopic rod 511 and the elastic positioning action of the elastic member 513, so that the powder on the top of the filter screen plate 514 can be effectively The separation work allows the large particles of impurities inside to be separated and move to the side close to the impurity discharge pipe 509 under the action of vibration, so that the separated large particles of impurities are discharged through the impurity discharge pipe 509 and collected by the impurity collection box 4, which is convenient for subsequent processing work, while normal powder enters the interior of the lifting cylinder 202 through the feed pipe 507, and the first driving mechanism 204 is started to drive the first driving rod 205 to rotate, so that the first spiral blade 206 rotates and drives the powder inside the lifting cylinder 202 to be lifted and transported upward. When the powder moves to the top of the discharge pipe 203, it will be discharged through the inside of the discharge pipe 203, and the lifting work of the powder can be completed.

[0036] Compared with the prior art, the powder lifting device, through the coordinated use of the lifting component 200 on the top of the lifting chassis 1 and the linear conveying component 500, can conveniently and effectively separate impurities and lift the powder, so that the powder can be stably and smoothly transported to the inside of the structure for impurity separation, so that the powder will not be separated in a piled state, which greatly reduces the possibility of normal powder being discharged by mistake, so that the lifting work of the powder can be carried out normally and effectively, and the workload of the staff is saved, thereby effectively improving the practicability of the powder lifting device and solving the problem that the existing powder elevator is prone to cause normal powder to be discharged together when performing impurity separation.

The main controller can be a conventional known device for control such as a computer, which can be realized through simple programming by technicians in the field. They are all existing public power connection technologies and will not be described in detail in the article.
