Description

Technical Field

[0001] This utility model belongs to the field of zinc smelting technology, and in particular relates to a mixed material conveying device for zinc smelting. Background Technology

[0002] Zinc smelting (especially the hydrometallurgical process) is a highly integrated and automated complex industrial process. The resulting substances include not only the main product, zinc ingots, and the important byproduct, sulfuric acid, but also various metal-containing slags, dust, sludge, wastewater, and waste gases. All of these need to be properly treated and utilized as resources. During the processing of these mixtures, conveying devices are required to transport the mixtures in order to shorten transportation time and improve work efficiency.

[0003] However, it still has the following drawbacks in practical use:

[0004] 1. Most existing zinc smelting mixing conveyor devices directly transport solid mixtures via conveyor belts during use. As the solid mixtures fall and come into direct contact with the conveyor belts during transportation, prolonged use will cause wear on the conveyor belts and affect their service life.

[0005] 2. Existing zinc smelting mixture conveying devices use a vacuum cleaner to extract solid mixture dust during operation. Since the filtered air is directly discharged, energy loss is likely, and the device's function is relatively limited. Therefore, we provide a zinc smelting mixture conveying device to solve the aforementioned problems. Utility Model Content

[0006] The purpose of this utility model is to provide a mixed material conveying device for zinc smelting. By setting up protective components, a first flexible plate and a second flexible plate receive the solid mixed material, which protects the conveying plate and prevents the conveying plate from being worn by the solid mixed material for a long time, thus affecting its service life. The pressing component can extract the dust generated during the falling of the solid mixed material, ensuring a clean environment. At the same time, filtered air is sprayed out to flatten and press the solid mixed material, ensuring efficient transportation of the solid mixed material and preventing the accumulation of solid mixed material from affecting transportation efficiency.

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model is a mixed material conveying device for zinc smelting, including a conveying frame and a sealing cover installed on its top. The conveying frame is provided with a conveying plate inside, and the outer wall of the conveying plate is provided with partitions arranged in an array along its movement direction. The outer side of the partitions is provided with a protective component, and the bottom of the conveying frame is provided with a pressing component.

[0009] The protective component includes a first flexible plate and a second flexible plate that are slidably inserted into the two side walls of the partition, and a sliding plate is fixed on the opposite end face of the first flexible plate and the second flexible plate;

[0010] The pressing assembly includes a dust collection box installed on one side of the bottom of the conveyor frame, and an air outlet pipe located at the bottom of one side wall of the dust collection box. The other end of the air outlet pipe is connected to the air inlet of the fan through a pipe joint. A filter screen is installed at one bottom end inside the dust collection box.

[0011] The present invention is further configured such that a feeding frame is provided at one end of the top of the sealing cover, a sliding groove is provided below the two side walls of the partition, and limit holes are arranged in an array from front to back above the two side walls of the partition.

[0012] The present invention is further configured such that the slide plate is slidably inserted into the inside of the slide groove, and bolts are inserted through the first soft plate and the second soft plate in an array from front to back, with nuts threaded on the outer wall of the bolts.

[0013] The present invention is further configured such that a dust inlet pipe is provided at the top center of the dust collection box, and the other end of the dust inlet pipe is connected to the first connecting pipe and the second connecting pipe respectively through a three-way connector. The other end of the first connecting pipe is connected to the first suction pipe through a pipe connector.

[0014] The present invention is further configured such that the other end of the first suction pipe is located on one side of the feed frame, the other end of the second connecting pipe is connected to the second suction pipe through a pipe joint, and the other end of the second suction pipe is located at the bottom of the outer wall of the sealing cover.

[0015] The present invention is further configured such that the air outlet end of the fan is connected to the third connecting pipe via a pipe joint, and the other end of the third connecting pipe is connected to the diversion pipe via a pipe joint.

[0016] The present invention is further configured such that nozzles are evenly spaced along the horizontal direction on the outer wall of the diverter pipe, and nozzles are arranged in an array from front to back at the bottom of the nozzles, with the nozzles located inside the sealing cover.

[0017] This utility model has the following beneficial effects:

[0018] 1. This utility model, by setting up protective components, with the first and second soft plates receiving the solid mixture, plays a protective role for the conveyor plate, avoiding the conveyor plate being worn by the solid mixture for a long time, thus affecting its service life. It solves the problem that existing zinc smelting mixture conveying devices mostly transport solid mixtures directly through the conveyor belt, and because the solid mixture falls and comes into direct contact with the conveyor belt during transportation, long-term use will cause wear to the conveyor belt and affect its service life.

[0019] 2. This utility model, by setting up a pressing component, allows the fan to extract dust generated during the falling of the solid mixture, ensuring a clean environment. At the same time, the filtered air is sprayed out to flatten and press the solid mixture, ensuring efficient transportation of the solid mixture and preventing the accumulation of solid mixture from affecting transportation efficiency. This solves the problem that existing zinc smelting mixture conveying devices use a vacuum cleaner to extract dust from the solid mixture, but the filtered air is directly discharged, which easily causes energy loss and has a relatively simple function.

Detailed Implementation

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0029] Please see Figures 1 to 4 This utility model is a mixed material conveying device for zinc smelting, including a conveying frame 100 and a sealing cover 101 installed on its top. The conveying frame 100 is provided with a conveying plate 103 inside. The outer wall of the conveying plate 103 is provided with partitions 104 arranged in an array along its movement direction. The outer side of the partitions 104 is provided with a protective component 200. The protective component 200 includes a first flexible plate 201 and a second flexible plate 202 slidably inserted into the two side walls of the partitions 104. Slide plates 201a are fixed on the opposite end faces of the first flexible plate 201 and the second flexible plate 202.

[0030] Specifically, a feed frame 102 is provided at one end of the top of the sealing cover 101, and a sliding groove 104a is provided below the two side walls of the partition 104. Limiting holes 104b are arranged in an array from front to back on the upper side walls of the partition 104. The slide plate 201a is slidably inserted into the inside of the sliding groove 104a. Bolts 203 are inserted through the first flexible plate 201 and the second flexible plate 202 in an array from front to back. Nuts 204 are threaded onto the outer wall of the bolts 203.

[0031] Furthermore, the sealing cover 101 can reduce dust spillage and maintain a clean working environment. The conveyor plate 103 is driven by a drive mechanism, which is existing technology and will not be described in detail here. The first flexible plate 201 and the second flexible plate 202 are made of flexible material, which is beneficial for protecting the conveyor plate 103 and can also move smoothly in the bending position. The threads on the outer wall of the bolt 203 are threadedly connected to the nut 204 to realize the assembly and disassembly of the first flexible plate 201 and the second flexible plate 202. The bolt 203 passes through the first flexible plate 201, the limiting hole 104b and the second flexible plate 202 to realize the installation of the first flexible plate 201 and the second flexible plate 202.

[0032] The operation process of this embodiment is as follows: During the zinc smelting process, a large amount of solid mixture is generated. In order to quickly transport these solid mixtures to the next stage, a conveying device is generally used to achieve rapid transport of the solid mixtures. Before the equipment is put into use, multiple sets of first flexible plates 201 and second flexible plates 202 are slidably inserted into the slide groove 104a under the action of the slide plate 201a, so that the first flexible plates 201 and second flexible plates 202 cover the outside of the partition plate 104. Then, bolts 203 are used to pass through the first flexible plates 201 and the limiting holes. 104b and the second flexible plate 202 are then connected, and then the nut 204 is sleeved on the end of the bolt 203 under the action of the thread, fixing the first flexible plate 201 and the second flexible plate 202 to the surface of the conveying plate 103. When conveying solid mixture, the solid mixture will fall onto the surface of multiple sets of first flexible plates 201 and second flexible plates 202. The first flexible plates 201 and the second flexible plates 202 are used to convey solid mixture, which protects the conveying plate 103 and prevents the conveying plate 103 from being worn by solid mixture for a long time, thus affecting its service life. Example 2

[0033] Please see Figure 2 and Figure 5 Based on Embodiment 1, the difference from the first embodiment is that a pressing assembly 300 is provided. The pressing assembly 300 includes a dust collection box 301 installed on one side of the bottom of the conveyor frame 100, and an air outlet pipe 301f set at the bottom of one side wall of the dust collection box 301. The other end of the air outlet pipe 301f is connected to the air inlet of the fan 302 through a pipe joint. A filter screen 305 is installed at one bottom end of the dust collection box 301. This solves the problem that the existing zinc smelting mixed material conveying device extracts solid mixed material dust by vacuuming, and the filtered air is directly discharged, which easily causes energy loss and has a relatively simple function.

[0034] Specifically, a dust inlet pipe 301a is provided at the top center of the dust collection box 301. The other end of the dust inlet pipe 301a is connected to the first connecting pipe 301b and the second connecting pipe 301d respectively through a three-way connector. The other end of the first connecting pipe 301b is connected to the first suction pipe 301c through a pipe connector. The other end of the first suction pipe 301c is located on one side of the feed frame 102. The other end of the second connecting pipe 301d is connected to the second suction pipe 301e through a pipe connector. The other end of the second suction pipe 301e is located at the bottom of the outer wall of the sealing cover 101. The air outlet of the fan 302 is connected to the third connecting pipe 302a through a pipe connector. The other end of the third connecting pipe 302a is connected to the diversion pipe 303 through a pipe connector. Spray pipes 304 are evenly spaced along the horizontal direction on the outer wall of the diversion pipe 303. The bottom of the spray pipes 304 is arranged with nozzles 304a in an array from front to back, and the nozzles 304a are located inside the sealing cover 101.

[0035] Furthermore, the three-part connector and pipe connector enable the connection of the pipeline. The filter screen 305 can filter dust to prevent dust from entering the fan 302 and affecting the normal operation and safety of the fan 302. The nozzle 304a is installed inside the sealing cover 101 and is set at an angle, which is more conducive to blowing the solid mixture on the traditional conveyor belt.

[0036] The operation process of this embodiment is as follows: when the solid mixture falls onto the conveying device through the feeding frame 102 and when the solid mixture is put into the next process, the fan 302 is started. The fan 302 operates to draw air from the dust collection box 301. Due to the reduction of air in the dust collection box 301, a negative pressure is formed. External air is drawn through the first suction pipe 301c and the second suction pipe 301e. At the same time, the dust generated during the falling of the solid mixture is sucked into the dust collection box 301. The air filtered by the filter screen 305 is drawn out by the fan 302 and then diverted by the diversion pipe 303 to multiple spray pipes 304. Finally, it is sprayed out by multiple nozzles 304a into the interior of the sealing cover 101. The high-pressure air sprayed out can flatten and press the solid mixture onto the surface of the conveying device, ensuring the efficient transportation of the solid mixture and avoiding the accumulation of solid mixture that affects the transportation efficiency.
