Description

Technical Field

[0001] The present application relates to the technical field of cyclone separators, and in particular to a cyclone separator for dry preparation of copper chloride and an operating method thereof. Background Art

[0002] The main raw materials for preparing copper chloride by dry method include high-purity copper powder and chlorine gas. Under high temperature and appropriate pressure conditions, a chemical reaction occurs between copper element and chlorine gas to generate copper chloride gas, which is then gradually cooled to form copper chloride solid particles.

[0003] In the process of collecting copper chloride solid particles in the cooling section, a cyclone separator is usually used to collect and separate them. However, since the slope of the cyclone separator cylinder wall is fixed, solid particles of different particle sizes are affected by centrifugal forces to varying degrees during its actual operation. In the process of contacting the cyclone separator cylinder wall, larger solid particles may rebound and break away from the cylinder wall due to excessive centrifugal force, or smaller solid particles may fail to make effective contact with the cylinder wall due to small centrifugal force, and are discharged from the exhaust pipe with the airflow, resulting in the cyclone separator having a relatively poor stability and reliability in the separation and collection operation due to the large fluctuations in the effect of the solid particles.

[0004] Therefore, there is an urgent need for a cyclone separator device for dry preparation of cupric chloride to solve the defects existing in the above-mentioned existing cyclone separators during actual operation. Summary of the invention

[0005] The present application proposes a cyclone separator for the dry preparation of copper chloride and an operating method thereof, which can effectively separate solid particles of different particle sizes, and will not affect the separation and collection effects due to the different particle sizes of the solid particles, and has the advantages of high stability and reliability, so as to solve the problem that the slope of the cyclone separator cylinder wall is fixed, and thus in its actual operation process, solid particles of different particle sizes are affected by different degrees of centrifugal force. In the process of contacting with the cylinder wall of the cyclone separator, larger solid particles may rebound and break away from the cylinder wall due to excessive centrifugal force, or smaller solid particles may not be able to effectively contact the cylinder wall due to small centrifugal force, and are discharged from the exhaust pipe with the airflow, causing the effect of the cyclone separator in the separation and collection operation to fluctuate greatly due to the size of the solid particles.

[0006] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: a cyclone separator for the dry preparation of copper chloride, comprising an outer shell, a discharge pipe extending to the bottom of its inner cavity is fixedly installed at the bottom of the outer shell, a feed pipe extending to the top of its inner cavity is fixedly installed at the top of one side of the outer surface of the outer shell, an inner sleeve is movably sleeved at the bottom of the inner cavity of the outer shell, a connecting bracket is fixedly installed at the top of the inner sleeve, and the outer surface of the connecting bracket is in contact with the inner wall of the outer shell, an auger disc whose outer surface is in contact with the top of the inner wall of the outer shell is fixedly installed at the top of the connecting bracket, and the position of the auger disc corresponds to the position of the feed pipe, and at the same time, an exhaust component whose bottom end extends to the middle of the gas cavity is fixedly installed at the top of the outer shell.

[0007] Furthermore, the connecting bracket is configured as a spiral structure, and the spiral direction thereof is the same as the spiral direction of the auger disc.

[0008] Furthermore, the exhaust component includes an exhaust duct whose top portion of the outer surface is fixedly mounted on the top portion of the outer shell, a filter member that can move upward is clamped in the middle portion of the inner cavity of the exhaust duct, and the filter member and the exhaust duct are elastically connected via an elastic member, a first contact ring is fixedly sleeved in the middle portion of the outer surface of the filter member, and a second contact ring is fixedly sleeved on the inner wall of the exhaust duct and located above the first contact ring, and the first contact ring and the second contact ring are electrically connected to an alarm.

[0009] Furthermore, a control system is fixedly installed on one side of the outer surface of the shell, and an air supply pipeline connected to its inner cavity is fixedly installed on the side of the feed pipeline, and the other end of the air supply pipeline is unidirectionally connected to the air flow pipeline. At the same time, the first contact ring and the second contact ring form a feedback connection with the air flow pipeline through the control system.

[0010] Furthermore, the winding coil structure adopted by the second contact ring can generate different feedback signals due to the different contact positions between them during the contact process with the first contact ring, and regulate the air flow output of the air supply pipeline to the outer shell according to the change of the feedback signal between the first contact ring and the second contact ring.

[0011] Furthermore, a connecting pipe is fixedly mounted on the top of the filter component, and the top of the connecting pipe extends to the top of the inner cavity of the exhaust pipe.

[0012] An operating method of a cyclone separator for the dry preparation of copper chloride, comprising the following operating steps:

[0013] S1. The copper chloride solid particles are transported to the inner cavity of the outer shell through the feed pipe, and the auger disc is rotated under the impact of the airflow, and the inner sleeve is forced to rotate accordingly under the transmission action of the connecting bracket;

[0014] S2. Under the action of centrifugal force, the copper chloride solid particles transported from the feed pipe spirally descend along the inner wall of the outer shell, and the unreacted chlorine and other harmful gases are discharged into the exhaust gas treatment system through the exhaust component, thereby separating and collecting the copper chloride solid particles;

[0015] S3. When the air flow pressure of the copper chloride solid particles is large and the centrifugal force generated on the larger solid particles is large, the rebound force generated on the larger solid particles can be reduced as the inner sleeve rotates, so that the solid particles will not be separated from the inner wall of the inner sleeve due to rebound, and can be separated and collected in the cyclone separator;

[0016] S4. When the air flow pressure transported by the copper chloride solid particles is small and the centrifugal force generated on the smaller solid particles is small, the smaller copper chloride solid particles enter the exhaust duct along with the air flow and are filtered by the filter member, causing the filter holes on the filter member to be blocked;

[0017] S5. The filter member moves upward under the action of the airflow so that the first contact ring contacts the second contact ring, and while the alarm is triggered, the airflow pipeline is automatically triggered to increase the airflow output to the inner cavity of the outer shell, so as to increase the centrifugal force generated by the cyclone separator on the smaller copper chloride solid particles, so that the smaller copper chloride solid particles can contact the inner wall of the inner sleeve for separation and collection operations.

[0018] The present invention application has the following technical effects:

[0019] 1. The present application provides a cyclone separator for the dry preparation of copper chloride and an operating method thereof. With respect to the arrangement of an inner sleeve and an upper structure thereof, when larger solid particles come into contact with the inner wall of the inner sleeve, the inner sleeve can be rotated to reduce the rebound force exerted on them, so that they will not separate from the inner wall of the inner sleeve due to rebound. Furthermore, by increasing the airflow for conveying the copper chloride solid particles, while ensuring that larger solid particles will not rebound and separate, smaller copper chloride solid particles can be ensured to come into effective contact with the inner wall of the inner sleeve, so as to separate and collect them.

[0020] 2. The present application provides a cyclone separator for the dry preparation of copper chloride and an operating method thereof. With respect to the arrangement of the exhaust assembly and the structure thereon, when smaller solid particles move with the airflow and enter the exhaust duct due to insufficient centrifugal force, they can be filtered out by the filter component and cause the filter holes thereon to be blocked, so that the filter component moves upward under the influence of the airflow, so that the first contact ring contacts the second contact ring, and while triggering the alarm, the airflow pipeline can be automatically triggered to increase the airflow output to the inner cavity of the outer shell, so as to increase the centrifugal force generated by the cyclone separator on the smaller copper chloride solid particles, so that they can contact the inner wall of the inner sleeve for separation and collection operations, and the operability is good and the controllability is high.

DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0030] like Figure 1 , Figure 2 As shown, a cyclone separator for the dry preparation of copper chloride comprises an outer shell 1 which can be fixedly mounted on an operating table, a discharge pipe 3 extending to the bottom of its inner cavity is fixedly mounted on the bottom end of the outer shell 1, a feed pipe 8 extending to the top of its inner cavity is fixedly mounted on the top of one side of the outer surface of the outer shell 1, and the other end of the feed pipe 8 is connected to the material conveying system of the cooling section, and then the copper chloride fixed particles in the cooling section can be conveyed to the inner cavity of the outer shell 1 through the feed pipe 8 for separation and collection operations, an inner sleeve 4 is movably sleeved on the bottom of the inner cavity of the outer shell 1, three groups of connecting brackets 5 arranged in a ring array are fixedly mounted on the top of the inner sleeve 4, and the outer surface of the connecting bracket 5 is in contact with the inner wall of the outer shell 1, and an auger disc 6 whose outer surface is in contact with the top of the inner wall of the outer shell 1 is fixedly mounted on the top of the connecting bracket 5, and the position of the auger disc 6 corresponds to the position of the feed pipe 8. , and then when the copper chloride solid particles are transported in the feed pipe 8, the auger disc 6 can be forced to rotate under the impact of the airflow, and under the transmission action of the connecting bracket 5, the inner sleeve 4 can be synchronously driven to rotate. When larger solid particles come into contact with the inner wall of the inner sleeve 4, the inner sleeve 4 can be rotated to reduce the rebound force generated thereon, so that the particles will not be separated from the inner wall of the inner sleeve 4 due to rebound. Then, by increasing the airflow for transporting the copper chloride solid particles, while ensuring that larger solid particles will not rebound and separate, smaller solid particles can be effectively contacted with the inner wall of the inner sleeve 4. At the same time, an exhaust assembly 7 for exhausting airflow, the bottom end of which extends to the middle of the gas cavity, is fixedly installed at the top of the outer shell 1, and the top of the exhaust assembly 7 is connected to the exhaust gas treatment system to remove the unreacted chlorine and other harmful gases therein.

[0031] like Figure 3 As shown, in the present technical solution, the connecting bracket 5 is configured as a spiral structure, and the direction of the spiral is the same as the spiral direction of the auger disc 6, so that when it rotates with the auger disc 6, the inner wall of the outer shell 1 can be scraped to effectively prevent the copper chloride fixed particles from adhering thereto to form scaling problems.

[0032] like Figure 3 , Figure 4As shown, in the present technical scheme, the exhaust assembly 7 includes an exhaust duct 10 whose top of the outer surface is fixedly mounted on the top of the outer shell 1, a filter member 11 that can move upward is clamped in the middle of the inner cavity of the exhaust duct 10, the filter holes in the filter member 11 are set to a downward conical hole structure, and the filter member 11 and the exhaust duct 10 are elastically connected by an elastic member 13, a first contact ring 14 is fixedly sleeved in the middle of the outer surface of the filter member 11, and a second contact ring 15 is fixedly sleeved on the inner wall of the exhaust duct 10 and located above the first contact ring 14, the first contact ring 14 and the second contact ring 15 are electrically connected to the alarm, and then when smaller solid particles move with the airflow due to insufficient centrifugal force and enter the exhaust duct 10, they can be filtered by the filter member 11 and cause the filter holes thereon to be blocked, causing the filter member 11 to move upward under the influence of the airflow, so that the first contact ring 14 and the second contact ring 15 are in contact, and an alarm is sounded to remind the staff to make corresponding adjustments.

[0033] like Figure 1 , Figure 3 as well as Figure 5 As shown, in the present technical solution, a control system 2 is fixedly installed on one side of the outer surface of the outer shell 1, and an air supply pipeline 9 connected to its inner cavity is fixedly installed on the side of the feed pipe 8, and the other end of the air supply pipeline 9 is unidirectionally connected to the air flow pipeline. At the same time, the first contact ring 14 and the second contact ring 15 form a feedback connection with the air flow pipeline through the control system 2, and then when the first contact ring 14 and the second contact ring 15 come into contact and trigger the alarm, the air flow pipeline can be automatically triggered to increase the air flow output in the inner cavity of the outer shell 1, so as to increase the centrifugal force generated by the cyclone separator on smaller copper chloride solid particles, so that they can come into contact with the inner wall of the inner sleeve 4 for separation and collection operations.

[0034] In the present technical solution, the winding coil structure adopted by the second contact ring 15 can generate different feedback signals through the different contact positions between them during the contact process with the first contact ring 14, and regulate the air flow output of the air supply pipeline 9 to the outer shell 1 according to the change of the feedback signal between the first contact ring 14 and the second contact ring 15.

[0035] like Figure 4 As shown, in the present technical solution, a connecting pipe 12 is fixedly installed at the top of the filter member 11, and the top of the connecting pipe 12 extends to the top of the inner cavity of the exhaust pipe 10, thereby isolating the gas flowing in the exhaust pipe 10 from contact with the elastic member 13 through the connecting pipe 12, so as to effectively prevent the elastic member 13 from being corroded by unreacted chlorine or other harmful gases.

[0036] An operating method of a cyclone separator for the dry preparation of copper chloride, comprising the following operating steps:

[0037] S1, conveying copper chloride solid particles into the inner cavity of the outer shell 1 through the feed pipe 8, and under the impact of the airflow, the auger disc 6 rotates, and the inner sleeve 4 is forced to rotate accordingly under the transmission action of the connecting bracket 5;

[0038] S2. Under the action of centrifugal force, the copper chloride solid particles transported from the feed pipe 8 spirally descend along the inner wall of the outer shell 1, and the unreacted chlorine and other harmful gases therein are discharged to the exhaust gas treatment system through the exhaust component 7, thereby separating and collecting the copper chloride solid particles;

[0039] S3. When the air flow pressure of the copper chloride solid particles is large and the centrifugal force generated on the larger solid particles is large, the inner sleeve 4 can rotate to reduce the rebound force generated on the solid particles, so that the solid particles will not be separated from the inner wall of the inner sleeve 4 due to rebound, and can be separated and collected in the cyclone separator;

[0040] S4, when the air flow pressure transported by the copper chloride solid particles is small and the centrifugal force generated on the smaller solid particles is small, the smaller copper chloride solid particles enter the exhaust pipe 10 along with the air flow and are filtered by the filter member 11, causing the filter holes thereon to be blocked;

[0041] S5. The filter member 11 moves upward under the action of the airflow so that the first contact ring 14 and the second contact ring 15 come into contact with each other. When the alarm is triggered, the airflow pipeline can be automatically triggered to increase the airflow output to the inner cavity of the outer shell 1, so as to increase the centrifugal force generated by the cyclone separator on the smaller copper chloride solid particles, so that the smaller copper chloride solid particles can come into contact with the inner wall of the inner sleeve 4 for separation and collection operations.
