Description

Technical Field

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

[0002] As we all know, zinc powder is a gray powder with a metallic luster and a granular flake structure, and is mostly used for electroplating anti-corrosion. In the prior art, the zinc powder material processed and produced is often collected by a dust collection mechanism and stored in ton bags. However, since the high-temperature waste heat in the processing process is difficult to dissipate, heat accumulates during the storage process and even ignites surrounding objects, posing a huge safety hazard and requiring rapid cooling.

[0003] The Chinese utility model patent discloses an anti-oxidation cooling device for zinc powder (publication number CN204997063U), which includes: a cooling bin, a loading port, an anti-oxidation cover plate, a discharge port, and a discharge valve. The funnel-type cooling bin is used. After the new zinc powder to be cooled is produced, the zinc powder can be directly poured in through the loading port at the top. When the zinc powder is cooled, the zinc powder can be conveniently transferred through the discharge port and the discharge valve at the bottom. In addition, the anti-oxidation cooling device is equipped with a cover plate above the cooling bin, and gaskets for sealing are embedded around the cover plate to ensure that the cooling bin is not circulated with air when the cover plate is covered, thereby reducing the oxidation of the zinc powder.

[0004] However, when the inventors implemented this device, they found the following defects: after the zinc powder is cooled by the funnel-type cooling bin, it is stored in ton bags. The cooling time of the zinc powder is long, which affects the efficiency of zinc powder bagging and has certain limitations in use. Utility Model Content

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0025] As described in the background art, an anti-oxidation cooling device for zinc powder cools the zinc powder through a funnel-type cooling bin and then stores the zinc powder in ton bags. The cooling time of the zinc powder is long, which affects the bagging efficiency and has certain limitations in use.

[0026] In order to solve this technical problem, the utility model provides a zinc powder cooling device, which is used for bagging and cooling of zinc powder.

[0027] Specifically, please refer to Figure 1-6 The zinc powder cooling device specifically comprises: a frame 1, a hanger 2 installed on the frame 1, and a follow-up cooling mechanism for cooling the zinc powder during bagging. The follow-up cooling mechanism comprises a cooling cylinder 3 installed on the hanger 2 for upward and downward movement, a telescopic bobbin 4, and a first lifting driver 5 for lifting the cooling cylinder 3. The first lifting driver 5 is fixedly installed on the hanger 2. One end of the telescopic bobbin 4 is fixedly connected to the frame 1 and extends from the top of the frame 1. The other end of the telescopic bobbin 4 is connected to the top of the cooling cylinder 3. A loading bin 6 is installed on the frame 1. A discharge pipe 7 extending toward the outer wall of the cooling cylinder 3 is installed at the bottom of the bin 6; further, the cooling cylinder 3 contains a cooling medium that is easy to absorb heat and evaporate, and the cooling medium can be water or other equivalent coolants with good heat absorption and evaporation effects; the first lifting drive 5 is preferably a driving cylinder, which is fixedly mounted on the hanger 2, and the output end of the driving cylinder is fixedly connected to the cooling cylinder 3; the first lifting drive 5 can also use other equivalent parts that have the effect of driving the cooling cylinder 3 to move downward, and the cooling medium in the cooling cylinder 3 evaporates and absorbs heat, which can accelerate the cooling of the zinc powder by the cooling cylinder 3.

[0028] The zinc powder cooling device provided by the utility model suspends the ton bag in an open state at the bottom of the hanger 2, and the cooling cylinder 3 is located at the bottom of the ton bag, and the zinc powder is guided to the outer wall of the cooling cylinder 3 through the feeding bin 6 and the discharge pipe 7. As the zinc powder continuously enters the ton bag, the outer wall of the cooling cylinder 3 is gradually surrounded by the zinc powder, and the cooling medium in the cooling cylinder 3 absorbs heat, and the zinc powder in contact with the outer wall of the cooling cylinder 3 can be cooled. The zinc powder absorbs heat through the cooling cylinder 3 during the process of feeding into the ton bag along the outer wall of the cooling cylinder 3, and the zinc powder naturally scatters during the falling process. The zinc powder itself naturally dissipates heat after being dispersed and contacted with the surrounding air, and the heat of the zinc powder in the ton bag is absorbed by the cooling cylinder 3. As the amount of zinc powder in the ton bag continues to increase, the first lifting driver 5 drives the cooling cylinder 3 to move upward step by step, and the zinc powder in the ton bag is gradually cooled from bottom to top. The zinc powder is synchronously cooled during the zinc powder bagging process, which can improve the cooling effect of the zinc powder and shorten the cooling time without affecting the zinc powder bagging.

[0029] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] Example 1

[0033] Please refer to Figure 1-5 A zinc powder cooling device comprises a frame 1, a hanger 2 mounted on the frame 1, and a follow-up cooling mechanism for cooling the zinc powder during bagging. The follow-up cooling mechanism comprises a cooling cylinder 3 mounted on the hanger 2 for upward and downward movement, a telescopic bobbin 4, and a first lifting driver 5 for lifting the cooling cylinder 3. The first lifting driver 5 is fixedly mounted on the hanger 2. One end of the telescopic bobbin 4 is fixedly connected to the frame 1 and extends from the top of the frame 1. The other end of the telescopic bobbin 4 is connected to the top of the cooling cylinder 3. A loading bin 6 is provided, and a discharge pipe 7 extending toward the outer wall of the cooling cylinder 3 is installed at the bottom of the loading bin 6; there are two groups of loading bins 6, and the two groups of loading bins 6 are symmetrically arranged on both sides of the frame 1; a blower 8 is installed on the frame 1, and there are two groups of blowers 8, and the two groups of blowers 8 are symmetrically arranged on the frame 1, and the air suction ports of the blower 8 are respectively adjacent to the two loading bins 6, and the air outlet ends of the blower 8 extend into the cooling cylinder 3; more specifically, the top of the telescopic barrel 4 can be connected to an external exhaust duct, and the evaporated cooling medium is discharged and then condensed and recovered.

[0034] The zinc powder cooling device provided in this embodiment can further disperse the zinc powder for loading through two groups of loading bins 6, thereby increasing the contact area between the zinc powder and the air, and at the same time increasing the contact area between the zinc powder and the outer wall of the cooling cylinder 3, so as to improve the heat dissipation effect of the zinc powder; and the input end of the blower 8 can suck the zinc powder dust flying near the loading bin 6 into the cooling cylinder 3, and adsorb it through the cooling medium in the cooling cylinder 3. At the same time, due to the blowing of new air into the cooling cylinder 3, the evaporation rate of the cooling medium in the cooling cylinder 3 can be increased, thereby improving the heat dissipation effect of the cooling cylinder 3 itself, so that the temperature at the cooling cylinder 3 is in a low temperature state.

[0035] Example 2

[0036] The zinc powder cooling device provided in Example 1 is further optimized, specifically, as follows: Figure 4-6 As shown, a plurality of circumferentially evenly distributed spaced heat dissipation plates 9 are provided on the outer wall of the cooling cylinder 3; a plurality of through holes 10 penetrating vertically and frontally are provided on the spaced heat dissipation plates 9.

[0037] In the zinc powder cooling device provided in the present embodiment, the spacer heat sink 9 can increase the contact area between the cooling cylinder 3 and the zinc powder in the ton bag, thereby facilitating the cooling cylinder 3 to absorb the heat of the zinc powder, and the through hole 10 can allow the zinc powder to pass through. When the zinc powder passes through, it is further dispersed and contacts with the external cold air to accelerate the heat dissipation of the zinc powder. At the same time, it is beneficial for the heat of the zinc powder at the bottom of the ton bag to be dissipated to the outside through the through hole 10, so as to further improve the cooling effect of the zinc powder in the ton bag.

[0038] Specifically, the hanger 2 is slidably installed on the frame 1 up and down, and the frame 1 is equipped with a second lifting drive 11 that provides power for the hanger 2 to move up and down; further, the second lifting drive 11 is preferably a driving cylinder, which is fixedly installed on the frame 1, and the output end of the driving cylinder is fixedly connected to the hanger 2; the second lifting drive 11 can also adopt other equivalent parts with lifting drive functions; in the process of adding zinc powder into the ton bag, the hanger 2 can be driven up and down by the second lifting drive 11, and the ton bag is deformed under the action of tension, so that the zinc powder in the ton bag gathers to the cooling cylinder 3 to ensure that the zinc powder in the ton bag is in full contact with the cooling cylinder 3, thereby ensuring the cooling effect of the zinc powder.

[0039] Specifically, a clamp 12 for hanging the sling on the ton bag is installed on the hanger 2; further, the clamp 12 is preferably a mechanical clamp, more specifically, the mechanical clamp includes an arc-shaped baffle rod fixedly installed on the hanger 2, a hook hingedly installed on the hanger 2, and a driving cylinder providing power for the rotation of the hook, and the arc-shaped baffle rod and the hook form a closed loop after contact, and the sling on the ton bag is built into the closed loop; through the clamp 12, the convenience of disassembly and assembly of the sling on the ton bag and the hanger 2 can be improved.

[0040] Specifically, it also includes a conveyor 13 located at the bottom of the frame 1; further, the conveyor 13 can adopt an equivalent conveying device with a conveying function such as a belt conveyor or a roller conveyor; the cooled and bagged zinc powder can be moved out from the bottom of the frame 1 through the conveyor 13, which is more convenient and labor-saving.

[0041] Specifically, a liquid injection pipe 14 extending into the cooling cylinder 3 is installed on the top of the frame 1, and a switch valve 15 is installed on the liquid injection pipe 14; the cooling medium can be added to the cooling cylinder 3 through the liquid injection pipe 14 to improve the convenience of adding the cooling medium in the cooling cylinder 3, and in the non-filling state, the switch valve 15 is in a closed state.

[0042] The use process of the zinc powder cooling device provided by the utility model is as follows: a ton bag is placed on the feeding end of the conveyor 13, and the sling on the ton bag is hung on the clamp 12 on the hanger 2. In the initial state, the cooling cylinder 3 is located at the bottom of the ton bag, and the blower 8 is started to blow the external air into the cooling cylinder 3 to accelerate the evaporation of the cooling medium in the cooling cylinder 3, and the zinc powder is guided to the outer wall of the cooling cylinder 3 through the feeding bin 6 and the discharge pipe 7. As the zinc powder continues to enter the ton bag, the outer wall of the cooling cylinder 3 is gradually surrounded by the zinc powder, and the cooling medium in the cooling cylinder 3 is absorbed. Heat can be used to cool the zinc powder in contact with the outer wall of the cooling cylinder 3. The zinc powder absorbs heat through the cooling cylinder 3 during the process of loading into the ton bag along the outer wall of the cooling cylinder 3. The zinc powder naturally scatters during the falling process. The zinc powder itself naturally dissipates heat after being dispersed and contacted with the surrounding air, and the heat of the zinc powder in the ton bag is absorbed by the cooling cylinder 3. As the amount of zinc powder in the ton bag continues to increase, the first lifting drive 5 drives the cooling cylinder 3 to move upward step by step, and the zinc powder in the ton bag is gradually cooled from bottom to top. After the zinc powder in the ton bag is cooled and packaged, it can be transferred to the required place through the conveyor 13.
