Description

Technical Field

[0001] This utility model relates to the technical field of precious metal smelting, filtration and recovery equipment, specifically a dust collector. Background Technology

[0002] Precious metal (gold, silver, and platinum group metals, etc.) smelting and filtration recovery equipment is a dust removal device that separates solid dust from the dust-laden gas after precious metal smelting by passing it through a certain filter material. Filter dust collectors mainly use woven fiber materials as the filter medium in baghouse dust collectors. The main problem with this type of dust collector is that precious metal powder adheres to the filter bag, requiring periodic incineration of the filter bag to extract the precious metal, resulting in resource waste. If the filter bag is damaged during use and dust leaks, it will also cause loss and waste of precious metals.

[0003] Chinese Utility Model Patent Publication No. CN 220736845 U discloses a water bath dust collector for precious metal smelting. This dust collector has an outlet at the bottom of the housing, and a quick-connect flange connects to the upper inlet of a receiving trolley. A water inlet pipe is connected to the housing. The receiving trolley is equipped with a drain pipe and a drain valve. This utility model uses water to filter dust-laden gas, resulting in more thorough filtration, recovery, and dust removal. It is convenient to use, can completely recover precious metals, and has a simple structure and low equipment cost. However, this water bath dust collector for precious metal smelting lacks a detachable baffle structure. The bent baffle surface is prone to dust accumulation, which, if not cleaned regularly, may affect the airflow channel and even breed bacteria, thus reducing its practicality.

[0031] Example 1: As Figure 1-8As shown, the dust collector provided by this utility model includes a housing 1, a top cover 2, and a support base 3 located at the bottom of the housing 1. Mounting blocks 15 are fixedly installed at both the front and rear ends of the inner wall of the housing 1. A slot 16 is opened at the end of the mounting block 15 near the top cover 2.

A reinforcing member 19 for strengthening the air inlet 4 is fixedly installed on the inner wall of the housing 1. A liquid outlet pipe 23 is provided on the outer side of the discharge hopper 21. The advantages are that the air inlet 4 facilitates the entry of dust-laden gas into the channel, the radar level gauge 5 can monitor the liquid level in the housing 1 in real time, and it is convenient to replenish or discharge the liquid in a timely manner; the liquid inlet pipe 6, together with the manual ball valve 7, facilitates the manual control of liquid injection by the operator; the air outlet 14 facilitates the discharge of purified gas from the housing 1; the reinforcing member 19 enhances the installation stability of the air inlet 4 and prevents loosening due to airflow impact; and the liquid outlet pipe 23 can discharge the liquid in the housing 1.

[0033] Specifically, positioning seats 8 are fixedly installed on both sides of the end of the housing 1 near the top cover 2. A groove 9 is formed on the end of the housing 1 near the top cover 2. A positioning post 10 is fixedly installed on the end of the positioning seat 8 away from the housing 1. Positioning grooves 11 are formed on both sides of the top cover 2 near the housing 1. A mating part 12 for plug-in installation is provided on the side of the top cover 2 away from the housing 1. A sealing strip 13 is adhesively installed on the end of the top cover 2 near the housing 1. The advantages are that the positioning seats 8 and positioning posts 10 cooperate to achieve precise positioning of the top cover 2, which is convenient for quick installation and disassembly. The groove 9 and sealing strip 13 cooperate to effectively prevent gas leakage and ensure the sealing of the dust removal process. The setting of the mating part 12 further enhances the connection stability, improves the overall structural strength, reduces the problem of connection loosening caused by vibration and other factors, and improves the reliability and service life of the equipment.

[0034] Specifically, latches 26 are fixedly installed on both the front and rear sides of the outer wall of the hopper 21, and latches 27 for connecting with the latches 26 are fixedly installed on both the front and rear sides of the outer wall of the receiving cart 22.

The advantages are that the cooperation of the latches 26 and the latches 27 allows the receiving cart 22 to be quickly installed and separated from the hopper 21, which facilitates the cleaning of precious metals collected in the receiving cart 22. The handle 28 makes it easy for operators to move the receiving cart 22, improving the convenience of equipment use, improving the material collection and cleaning process of the dust collector, and reducing the intensity of manual labor.

[0035] Example 2:

[0036] like Figure 2-8 As shown, as an improvement over the previous embodiment, this facilitates better filtration of precious metal particles. Specifically, the positioning groove 11 is adapted to the positioning seat 8, and the positioning groove 11 and the positioning seat 8 are installed by insertion. The sealing strip 13 can be snapped into the groove 9, and the mating part 12 and the positioning post 10 are installed by snap-fit. The advantages are that the insertion installation of the positioning groove 11 and the positioning seat 8 ensures accurate installation position, avoids trial and error, and improves installation efficiency. The sealing strip 13 is snapped into the groove 9, which effectively enhances the sealing effect. Furthermore, the snap-fit ​​installation of the mating part 12 and the positioning post 10 improves the connection firmness.

[0037] Specifically, the insert 18 and slot 16 are plug-in installed. Five identical sets of baffles 17 are provided, equidistantly distributed on the inner side of the housing 1, with adjacent sets of baffles 17 arranged in a staggered, vertical arrangement. The advantage is that the plug-in design of the insert 18 and slot 16 facilitates the detachable installation of the baffles 17, making subsequent cleaning easier. The five equidistant and staggered baffles 17 extend the gas flow path within the housing 1, increasing the gas-liquid contact time and allowing for more thorough dust capture, significantly improving dust removal efficiency.

[0038] Specifically, the first filter screen 20 and the second filter screen 24 are arranged vertically downwards in sequence, with the pore size of the second filter screen 24 being smaller than that of the first filter screen 20. The advantage is that by setting up the first filter screen 20 and the second filter screen 24, dust can be filtered in stages. Larger dust particles are first intercepted by the large-pore first filter screen 20, and then the smaller particles are filtered by the small-pore second filter screen 24, thus facilitating the entry of precious metal particles into the receiving cart 22.

[0039] Working Principle: During use, the design of the plug-in block 18 and slot 16 allows for the detachable installation of the baffle plate 17, facilitating future maintenance. Furthermore, the five sets of equally spaced and staggered baffle plates 17 extend the gas flow path within the housing 1, increasing the contact time between the gas and liquid, allowing for more thorough dust capture and significantly improving dust removal efficiency. Subsequently, the plug-in installation of the positioning groove 11 and positioning seat 8 ensures accurate positioning of the top cover 2, avoiding trial and error and thus improving safety. To improve installation efficiency, the sealing strip 13 is inserted into the groove 9, effectively enhancing the sealing effect of the dust collector. Furthermore, the snap-fit ​​installation of the mating part 12 and the positioning post 10 improves the overall structural strength, reduces loosening caused by vibration and other factors, and enhances the reliability and service life of the equipment. The cooperation of the latch 26 and the locking buckle 27 allows for quick installation and separation of the receiving cart 22 from the unloading hopper 21, facilitating the cleaning of precious metals collected within the receiving cart 22. The handle 28 facilitates the movement of the receiving cart 22 by the operator, improving equipment usability. The convenience of this system improves the material collection and cleaning process of the dust collector and reduces the intensity of manual labor. When starting the dust collector, the dust-laden gas enters the dust collector housing 1 through the air inlet 4 of the top cover 2. The reinforcing member 19 at the air inlet 4 ensures its stability and prevents displacement due to airflow impact. After the gas enters, it encounters five sets of staggered baffles 17 inside the housing 1, which prolongs the gas flow path and allows it to fully contact the liquid. At this time, the liquid is injected into the housing 1 through the liquid inlet pipe 6. The manual ball valve 7 can control the liquid inflow, and the radar level gauge 5 provides real-time monitoring. The liquid level in the monitoring chamber 1 is adjusted in a timely manner to regulate the liquid inlet flow. During the contact between the dust-laden gas and the liquid, impurities such as precious metals will separate and precipitate from the gas. By setting up a first filter screen 20 and a second filter screen 24, the dust can be filtered in stages. First, the larger dust particles are intercepted by the first filter screen 20 with a large aperture, and then the smaller particles are filtered by the second filter screen 24 with a small aperture, which makes it easier for precious metal particles to enter the receiving cart 22. At this time, the operator only needs to pull the scraper 25 to allow the precious metal particles to enter the receiving cart 22.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
