Description

Technical Field

[0001] The utility model relates to the technical field of filtration substrate production equipment, specifically, especially a reaction tank for producing molecular sieve substrates. Background Art

[0002] The molecular sieve filtration substrate is a core part for manufacturing a molecular sieve rotor. The molecular sieve filtration substrate is in a honeycomb-shaped embryo. Usually, during production, the embryo needs to be placed in a reaction tank, and a molecular sieve slurry is added into the reaction tank so that the embryo is immersed in the molecular sieve slurry to enable the molecular sieve material to combine with the embryo.

[0003] However, in the existing reaction tanks, the slurry is usually circularly heated by a circulation heater. However, during the process of the substrate embryo being immersed in the molecular sieve slurry, aeration is usually required in the tank body to make the slurry more uniform and at the same time enable the slurry to contact the embryo more fully. However, during the aeration process, since cold air is input, the temperature of the slurry in the reaction tank drops rapidly, thus affecting the efficiency of the combination of the molecular sieve material and the embryo. Summary of the Utility Model

[0004] In order to overcome the defects existing in the prior art, the utility model provides a reaction tank for producing molecular sieve substrates, aiming to solve the above technical problems.

[0007] An aeration device, the aeration device includes an aeration pipe located at the lower end inside the tank body. The aeration pipe is communicated with a connecting pipe. The connecting pipe is located outside the tank body, and the connecting pipe extends into the circulation heating unit to heat the gas in the connecting pipe.

[0008] In the reaction tank for producing a molecular sieve substrate described above, the circulating heating unit includes a box body. An installation cavity is arranged inside the box body.

Detailed Embodiment

[0016] The following further describes the specific implementation manners of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these implementation manners is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0017] Combined Figure 1 with Figure 2 A reaction tank for producing a molecular sieve substrate shown in the figure has a tank body 1. The reaction tank further includes a circulating heating unit 3 and an aeration device. The circulating heating unit 3 is installed on the outer side of the tank body 1. The feed end of the circulating heating unit 3 is communicated with the bottom 2 of the tank body 1. The upper end of the circulating heating unit 3 is provided with a discharge pipe 7, and the discharge pipe 7 is communicated with the tank body 1. The aeration device includes an air distribution pipe 11 located at the lower end inside the tank body 1. The air distribution pipe 11 is communicated with a connecting pipe 9. The connecting pipe 9 is located outside the tank body 1, and the connecting pipe 9 extends into the circulating heating unit 3 to heat the gas in the connecting pipe 9. In this embodiment, the circulating heating unit 3 circulates and heats the slurry in the tank body 1. At the same time, the connecting pipe 9 connected to the air distribution pipe 11 extends into the circulating heating unit 3 to preheat the air in the connecting pipe 9, and then the hot air is blown into the bottom of the tank body 1 to make the hot air tumble the slurry in the tank body 1, so that the slurry contacts the embryo more fully, and it can prevent the temperature of the slurry in the tank body 1 from dropping significantly, prevent the bonding efficiency between the molecular sieve material and the embryo from dropping significantly, and the preheating of the air in the connecting pipe 9 is also heated by the circulating heating unit 3, reducing energy consumption.

[0018] It is worth noting that the bottom 2 of this embodiment is conical, which can facilitate entry into the circulating heating unit 3.

[0019] The circulating heating unit 3 of this embodiment includes a box body 12. An installation cavity 13 is arranged inside the box body 12. A first circulating heater 14 and a second circulating heater 17 are installed in the installation cavity 13. A storage tank 15 is arranged at the upper end of the installation cavity 13. The input end of the first circulating heater 14 is communicated with the bottom of the pool 2, and the output end of the first circulating heater 14 is communicated with the input port of the storage tank 15. The input end of the second circulating heater 17 is communicated with the output port of the storage tank 15, and the output end of the second circulating heater 17 is communicated with the discharge pipe 7. A heat conduction pipe 16 is installed through the storage tank 15. The connecting pipe 9 is communicated with one end of the heat conduction pipe 16, and the other end is communicated with a blower 8. The blower 8 is installed on the outer side of the box body 12. First, the slurry is heated for the first time by the first circulating heater 14, then the slurry enters the storage tank 15, and then the heated slurry covers the surface of the heat conduction pipe 16, so that the heat conduction pipe 16 is heated and the gas passing through the inside is heated, so that the gas output from the aeration pipe 11 is not cold air, preventing the temperature of the slurry in the pool body 1 from being reduced. At the same time, the slurry in the storage tank 15 enters the second circulating heater 17 again for heating. Since the slurry entering the second circulating heater 17 already has a certain temperature, the power of the second circulating heater 17 can be relatively lower than that of the first circulating heater 14 to reduce power consumption.

[0020] It is worth noting that the height of the input port of the slurry entering the storage tank 15 in this embodiment is lower than the height of the output port; so that the storage tank 15 can store a certain height of slurry to make the slurry cover the surface of the heat conduction pipe 16.

[0021] A feed pipe 4 is communicated with the bottom of the pool 2 in this embodiment. The feed pipe 4 is communicated with a pump body 5. The output end of the pump body 5 is communicated with the input end of the first circulating heater 14 through an output pipe 6. The slurry in the pool body 1 is pumped into the first circulating heater 14 by the pump body 5, so that the slurry is continuously circulated and heated between the pool body 1 and the circulating heating unit 3.

[0022] It is also worth noting that the aeration pipe 11 in this embodiment is installed in the pool body 1 through an installation pipe 10. The installation pipe 10 is communicated with the connecting pipe 9. The aeration pipe 11 is uniformly arranged at the lower inner end of the pool body 1. A plurality of aeration holes are opened on the lower end surface of the aeration pipe 11. The slurry in the pool body 1 is aerated through the plurality of aeration holes, so that the slurry rolls and is in full contact with the embryo body.
