Description

Technical Field

[0001] The utility model relates to the technical field of cold dryers, in particular to a cold dryer which is anti-blocking and anti-leakage for the production of pigment carbon black. Background Art

[0002] The refrigerated compressed air dryer is based on the principle of air freeze drying. It uses refrigeration equipment to cool the compressed air to a certain dew point temperature, precipitate the corresponding water content, and separate the gas and liquid through a separator. The water is then discharged through an automatic drain valve to achieve the purpose of freezing and dehumidification. In the production process of pigment carbon black, after multiple processes, it is finally dried by a cold dryer.

[0003] At present, the existing cold dryer (such as patent number: CN219511140U) discloses a cold dryer, which processes impurities in cold air through a filtering component and an adsorption component. The processed cold air then enters the cold drying chamber through the air outlet and is recycled through the cold dryer body. In this way, the used cold air can be recycled, energy consumption can be reduced, and impurities scattered during the cold drying of materials can be prevented from polluting the air.

[0004] However, in the process of implementing the above technical solution, it was found that there were at least the following technical problems: after a period of use, impurities would accumulate in the filter element at the cooling water inlet and in front of the automatic drain, resulting in increased water flow resistance in front of the filter, affecting the water flow rate and causing drainage blockage. When blockage occurs, the staff cannot discover and clear it in time, affecting the normal use of the equipment. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] In view of the deficiencies in the prior art, the utility model provides a blockage-proof and leakage-proof cold dryer for the production of pigment carbon black, which solves the technical problem that after a period of use, impurities will accumulate in the filter elements at the cooling water inlet and in front of the automatic drainer, resulting in increased water flow resistance in front of the filter, affecting the water flow rate and causing drainage blockage. When blockage occurs, the staff cannot discover and clear it in time, affecting the normal use of the equipment.

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A blockage-proof and leakage-proof cold dryer for producing pigment carbon black comprises a machine body, a mounting plate is fixedly mounted inside the machine body, a filtering mechanism is fixedly mounted on the top of the mounting plate, the filtering mechanism comprises a filtering tank body and a drain pipe, an adjusting sleeve is movably mounted on the side end of the drain pipe, a baffle is fixedly mounted inside the adjusting sleeve, and a fixing plate is fixedly mounted on the surface of the adjusting sleeve.

[0010] Preferably: a plug is fixedly installed on the side end of the fixing plate, a positioning plate is fixedly installed on the top of the mounting plate, two reset rods are fixedly installed on the side end of the positioning plate, an extrusion switch is fixedly installed on the side end of the positioning plate, and two receivers are fixedly installed on the top of the mounting plate.

[0011] (III) Beneficial effects

[0012] 1. When impurities accumulate in the filter element inside the filter tank body, the flow inside the drain pipe decreases, and the thrust exerted by the cooling water on the baffle plate weakens. At this time, under the reverse force of the two reset rods, the reset rods exert reverse pulling force on the fixed plate, allowing the fixed plate to drive the adjusting sleeve to move to one side of the drain pipe. At the same time, the fixed plate drives the plug to insert into the top of the extrusion switch, triggering the positioning plate. Through the connecting wires on both sides of the positioning plate, a signal is sent to the body to remind the staff that the filter element inside the filter tank body needs to be cleaned and replaced to prevent the filter tank body from being blocked.

[0013] 2. The cooling water impacts one side of the baffle plate, generating a horizontal thrust on the baffle plate, causing the adjusting sleeve to slide to one side. At the same time, the adjusting sleeve drives the fixing plate to move, causing the fixing plate to drive the plug away from the side end of the extrusion switch. At the same time, the movement of the fixing plate applies a pulling force to the top of the reset rod, causing the reset rod to extend and retract at the side end of the positioning plate. The pulling force generated by the reset rod on the fixing plate drives the adjusting sleeve to automatically reset. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The embodiment of the present application provides a blockage and leakage-proof cold dryer for the production of pigment carbon black, which effectively solves the problem that after a period of use, impurities will accumulate in the filter element at the cooling water inlet and in front of the automatic drain, resulting in increased water flow resistance in front of the filter, affecting the water flow rate and causing drainage blockage. When blockage occurs, the staff cannot discover and clear it in time, affecting the normal use of the equipment. When impurities accumulate in the filter element inside the filter tank body, the flow inside the drain pipe is reduced, and the thrust exerted by the cooling water on the baffle plate is weakened. At this time, under the reverse force of the two reset rods, the reset rod exerts a reverse pulling force on the fixed plate, allowing the fixed plate to drive the adjusting sleeve to move to one side of the drain pipe. At the same time, the fixed plate drives the plug to be inserted into the top of the extrusion switch, triggering the positioning plate. Through the connecting lines on both sides of the positioning plate, a signal is sent to the machine body, reminding the staff that the filter element inside the filter tank body needs to be cleaned and replaced to prevent the filter tank body from being blocked.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in the embodiment of the present application effectively solves the technical problem that after a period of use, the filter at the cooling water inlet and the filter in front of the automatic drain will accumulate impurities in the filter element, resulting in an increase in water flow resistance in front of the filter, affecting the water flow, causing drainage blockage, and when blockage occurs, the staff cannot promptly discover and clear it, affecting the normal use of the equipment. The overall idea is as follows:

[0023] In view of the problems existing in the prior art, the utility model provides a blockage and leakage-proof cold dryer for pigment carbon black production, comprising a machine body 1, a mounting plate 11 is fixedly installed inside the machine body 1, a filtering mechanism is fixedly installed on the top of the mounting plate 11, the filtering mechanism comprises a filter tank body 12 and a drain pipe 13, an adjusting sleeve 14 is movably installed on the side end of the drain pipe 13, a baffle plate 15 is installed inside the adjusting sleeve 14, cooling water impacts one side of the baffle plate 15, generates a horizontal thrust on the baffle plate 15, causes the adjusting sleeve 14 to slide to one side, and at the same time the adjusting sleeve 14 drives the fixing plate 16 to move, and the fixing plate 16 drives the plug 21 to leave the side end of the extrusion switch 19, the baffle plate 15 is fixedly installed inside the adjusting sleeve 14, a filter plate is installed inside the filter tank body 12, and rubber sealing sleeves are respectively installed on both sides of the adjusting sleeve 14, the baffle plate 15 is a double-layer and mutually crossed design, and the fixing plate 16 is fixedly installed on the surface of the adjusting sleeve 14.

[0024] A plug 21 is fixedly installed on the side end of the fixing plate 16, and a positioning plate 17 is fixedly installed on the top of the mounting plate 11. Two reset rods 18 are fixedly installed on the side end of the positioning plate 17. The top of the reset rod 18 is connected to the fixing plate 16, and a spring block is installed inside the reset rod 18. Under the reverse force of the two reset rods 18, the reset rod 18 applies a reverse pulling force to the fixing plate 16, so that the fixing plate 16 drives the adjusting sleeve 14 to move to the side of the drain pipe 13. At the same time, the fixing plate 16 drives the plug 21 to insert the top of the squeeze switch 19, triggering the positioning plate 17. Through the connecting lines on both sides of the positioning plate 17, a signal is generated to the machine body 1, reminding the staff that the filter element inside the filter tank body 12 needs to be cleaned and replaced to prevent the filter tank body 12 from being blocked. The side end of the positioning plate 17 is fixedly installed with a squeeze switch 19, and the top of the mounting plate 11 is fixedly installed with two receivers 22.

[0025] Working principle:

[0026] In the first step, the separated carbon black is sent to a granulator for granulation, and then the obtained pigment carbon black is dried. A pipeline is installed at the top of the filter tank body 12, and a filter element is installed inside the filter tank body 12. Cooling water enters the inside of the filter tank body 12 for filtration, and is discharged to the outside through a drain pipe 13 installed on one side. Since the cooling water flows out to the outside through the drain pipe 13, the cooling water enters the inside of the adjustment sleeve 14, and a baffle plate 15 is installed inside the adjustment sleeve 14. The cooling water impacts one side of the baffle plate 15, and generates a horizontal thrust on the baffle plate 15, so that the adjustment sleeve 14 slides to one side, and at the same time, the adjustment sleeve 14 drives the fixing plate 16 to move, so that the fixing plate 16 drives the plug 21 to leave the side end of the extrusion switch 19, and at the same time, the movement of the fixing plate 16 applies a pulling force to the top of the reset rod 18, so that the reset rod 18 is retracted at the side end of the positioning plate 17, and at the same time, the positioning plate 17 is directly connected with the body 1 through the connecting line.

[0027] The second step, on the contrary, when the filter element inside the filter tank body 12 accumulates impurities, the flow inside the drain pipe 13 decreases, and the thrust exerted by the cooling water on the baffle 15 is weakened. At this time, under the reverse force of the two reset rods 18, the reset rod 18 exerts a reverse pulling force on the fixed plate 16, so that the fixed plate 16 drives the adjustment sleeve 14 to move to the side of the drain pipe 13. At the same time, the fixed plate 16 drives the plug 21 to insert the top of the extrusion switch 19, triggering the positioning plate 17. Through the connecting lines on both sides of the positioning plate 17, a signal is sent to the body 1 to remind the staff that the filter element inside the filter tank body 12 needs to be cleaned and replaced to prevent the filter tank body 12 from being blocked and affecting the use of the equipment. The ball valve in front of the filter tank body 12 is closed, the fixing screws at the top of the filter tank body 12 are loosened, the compressed air in the filter tank body 12 is released, the shell cover of the filter tank body 12 is released, and then the filter element is taken out and cleaned with clean water and a soft brush.

[0028] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
