Description

Technical Field

[0001] The utility model relates to the technical field of powder material transfer equipment, in particular to a powder material lifting cylinder and powder material transfer equipment. Background Art

[0002] At present, there are two ways to collect powder for domestic grinding equipment. The first is a steel tank body with a ton bag inside, or a ton bag directly at the discharge port. Because ton bags are generally open, dust is easily generated during collection, and they usually need to be cut before unloading, which is not economical and will cause secondary dust. The second is a powder collection cylinder, which is a straight cylinder (with a dust cover) with a cone bucket at the bottom. The cone bucket is fixed and placed by means of legs, and the discharge port below the cone bucket is connected to a valve. This method can avoid dust, but the valve needs to be closed or opened for loading and unloading, which is troublesome to operate. At the same time, a breaking arch device needs to be added to the center of the cone bucket to protect the valve to avoid direct impact and damage to the valve when the powder is unloaded. Therefore, it is necessary to design a powder lifting cylinder for collecting and transporting grinding powder, which is easy to operate and can achieve powder collection and unloading only by lifting and placing. Utility Model Content

[0003] In view of the above-mentioned problems in the prior art, the present application proposes a powder lifting cylinder and powder transfer equipment for collecting and transferring ground powder. The operation is simple and the powder can be collected and unloaded only by lifting and placing.

[0004] One aspect of the utility model provides a powder lifting cylinder, which comprises a collecting cylinder and a lifting rod, a dust cover is installed on the upper end of the collecting cylinder, a feeding hole and a breathing valve are provided on the dust cover, a conical feeding guide is installed on the inner side of the lower end of the collecting cylinder, a discharge port is provided at the tip of the conical feeding guide, a lifting ring is installed on the upper end of the lifting rod, and the lower end of the lifting rod passes through the dust cover and is connected to the tip of the cone bucket sealing body, and the lifting rod relative to the collecting cylinder along the axial movement of the collecting cylinder can cause the cone bucket sealing body to open or block the discharge port.

[0005] As a further improvement of the above technical solution:

[0006] The above-mentioned powder lifting cylinder, further, has an annular bottom plate installed at the lower end of the collecting cylinder, a cone bucket sealing plate is provided on the middle upper side of the annular bottom plate, the conical discharge guide plate is fixed on the cone bucket sealing plate, and when the cone bucket sealing body blocks the discharge port, the lower end of the cone bucket sealing body is higher than the annular bottom plate.

[0007] The above-mentioned powder lifting cylinder, further, the dustproof cover plate includes a first semicircular cover plate and a second semicircular cover plate that cooperate with each other, the first semicircular cover plate is fixedly installed on the upper end of the collecting cylinder, and the second semicircular cover plate is detachably installed on the upper end of the collecting cylinder, and a sealing plate is provided on the side of the first semicircular cover plate opposite to the second semicircular cover plate, and the sealing plate is used to seal the gap between the first semicircular cover plate and the second semicircular cover plate.

[0008] The powder lifting cylinder mentioned above, further, the dust cover plate is provided with a through hole, the lifting rod passes through the through hole, and the size of the lifting ring is larger than the size of the through hole.

[0009] Another aspect of the utility model provides a powder transporting device, which includes a hoisting device and the powder lifting cylinder as described above, wherein the hoisting device is used for hoisting and transporting the powder lifting cylinder.

[0010] The above technical features can be combined in various suitable ways or replaced by equivalent technical features as long as the purpose of the utility model can be achieved.

[0011] The utility model provides a powder lifting cylinder and powder transfer equipment, which have at least the following beneficial effects compared with the prior art: when grinding powder needs to be transferred, the powder lifting cylinder is first hoisted by a lifting ring and placed flat under the discharge port of the grinding equipment, the discharge port of the grinding equipment is connected with the feed hole of the powder lifting cylinder through a pipeline or a soft connection, and then the grinding equipment starts to discharge, and after the powder enters the collecting cylinder, the air goes out through the breathing valve on the cover plate to avoid the formation of negative pressure inside the collecting cylinder, which affects the entry of powder.

[0012] Then control the lifting device to directly hook the lifting ring on the upper end of the lifting rod through the lifting hook, and lift it to the top of the feed port of the powder storage silo (the top of the storage silo must be supported to carry the powder lifting cylinder). After manually visually adjusting the discharge port of the powder lifting cylinder to align with the feed port of the storage silo, slowly lower the powder lifting cylinder. After the powder lifting cylinder is placed flat on the top of the silo, continue to lower the lifting ring or loosen the lifting ring. The lifting rod and the cone bucket sealing mask body will drop simultaneously due to pressure and deadweight. The lifting ring cannot pass through the dust cover plate, which plays a limiting role. The powder will flow down through the gap between the conical unloading guide plate and the cone bucket sealing mask body. After unloading is completed, pull up the lifting ring again, the lifting rod will rise with the cone bucket sealing mask body, and the cone bucket sealing mask body will block the discharge port to prevent the powder collected in the cylinder from flowing out of the discharge port during transportation.

[0027] The embodiment of the utility model provides a powder lifting cylinder 100, which is used for collecting and transporting ground powder. The operation is simple and convenient, and the powder collection and unloading can be achieved only by lifting and placing.

[0028] See also Figure 1 The powder lifting cylinder 100 provided by the embodiment of the utility model includes a collecting cylinder 110 and a lifting rod 120. A dust cover 130 is installed on the upper end of the collecting cylinder 110. A feeding hole 131 and a breathing valve are provided on the dust cover 130. A conical material discharge guide plate 111 is installed on the inner side of the lower end of the collecting cylinder 110. A discharge port is provided at the tip of the conical material discharge guide plate 111. A lifting ring 121 is installed on the upper end of the lifting rod 120. The lower end of the lifting rod 120 passes through the dust cover 130 and is connected to the tip of the cone bucket sealing body 122. The lifting rod 120 moves relative to the collecting cylinder 110 along the axial direction of the collecting cylinder 110 to open or block the discharge port of the cone bucket sealing body 122.

[0029] When it is necessary to transport the grinding powder, firstly, the powder lifting cylinder 100 is hoisted by the lifting ring 121 and placed flat under the discharge port of the grinding equipment. The discharge port of the grinding equipment is connected with the feed hole 131 of the powder lifting cylinder 100 through a pipeline or a flexible connection, and then the grinding equipment starts to discharge. After the powder enters the collecting cylinder 110, the air goes out through the breathing valve on the cover plate to avoid the formation of negative pressure inside the collecting cylinder 110, which affects the entry of powder.

[0030] Then, the lifting device is controlled to directly hook the lifting ring 121 on the upper end of the lifting rod 120 through the lifting hook, and lift it to the top of the feeding port of the powder storage bin (the top of the storage bin must be supported to carry the powder lifting cylinder 100). After manually visually adjusting the discharge port of the powder lifting cylinder 100 to align with the feeding port of the storage bin, the powder lifting cylinder 100 is slowly lowered. After the powder lifting cylinder 100 is placed flat on the top of the silo, the lifting ring 121 is continued to be lowered or the lifting ring 121 is loosened, and the lifting rod 120 and the cone bucket are sealed. The mask body 122 will drop synchronously due to the pressure and its own weight, and the lifting ring 121 cannot pass through the dust cover 130, which plays a limiting role. The powder will flow down through the gap between the conical unloading guide plate 111 and the cone bucket sealing mask body 122. After unloading is completed, the lifting ring 121 is pulled up again, and the lifting rod 120 rises with the cone bucket sealing mask body 122. The cone bucket sealing mask body 122 blocks the unloading port to prevent the powder in the collection cylinder 110 from flowing out of the unloading port during the transportation process.

[0031] The powder lifting cylinder 100 provided in the embodiment of the present utility model, further, please refer to Figure 1 The lower end of the collecting cylinder 110 is provided with an annular bottom plate 140, and a cone bucket sealing plate 141 is provided on the upper middle side of the annular bottom plate 140. The conical material discharge guide plate 111 is fixed on the cone bucket sealing plate 141. When the cone bucket sealing housing 122 blocks the discharge port, the lower end of the cone bucket sealing housing 122 is higher than the annular bottom plate 140. The annular bottom plate 140 can support and fix the tip of the conical material discharge guide plate 111 to prevent the tip of the conical material discharge guide plate 111 from displacement and deformation. The cone bucket sealing plate 141 can fit with the outer side wall of the cone bucket sealing housing 122 to ensure the sealing of the discharge port.

[0032] The powder lifting cylinder 100 provided in the embodiment of the utility model is specifically described in conjunction with Figure 2The dust cover 130 includes a first semicircular cover 132 and a second semicircular cover 133 that cooperate with each other. The first semicircular cover 132 is fixedly mounted on the upper end of the collecting cylinder 110, and the second semicircular cover 133 is detachably mounted on the upper end of the collecting cylinder 110. A sealing plate 134 is provided on the side of the first semicircular cover 132 opposite to the second semicircular cover 133. The sealing plate 134 is used to seal the gap between the first semicircular cover 132 and the second semicircular cover 133. Removing the second semicircular cover 133 from the upper end of the collecting cylinder 110 can facilitate the installation of the lifting rod 120 and the cone bucket sealing housing 122. In this embodiment, a through hole 135 is provided on the dust cover 130, and the lifting rod 120 passes through the through hole 135, and the size of the lifting ring 121 is larger than the size of the through hole 135.
