[0029] Example 1

[0030] Reference Figure 1 This is the first embodiment of the present invention, providing a catalyst honeycomb zeolite manufacturing apparatus. The apparatus includes a molding unit 100, comprising a feeding pipe 101, an outlet 102 at one end of the feeding pipe 101, a die 103 fixed at the outlet 102, an air supply pipe 104 installed above the feeding pipe 101, and a housing 105 connecting the feeding pipe 101 and the air supply pipe 104 at the outlet 102. A cutting blade 106 is disposed inside the housing 105 near the feeding pipe 101. A transport unit 200 includes a [missing information - likely a component or part of the apparatus]. The conveyor belt 201 inside the shell 105 has a storage chamber 202 located below the end of the conveyor belt 201 away from the discharge port 102. The storage chamber 202 is surrounded by a metal mesh 203 on its sides and bottom. Four identical metal traction ropes 204 are fixedly installed at the four corners of the top of the storage chamber 202. The growth unit 300 includes an immersion chamber 301 fixedly installed below the end of the conveyor belt 201 away from the discharge port 102. The storage chamber 202 is placed in the immersion chamber 301. A heating chamber 302 is located on the side of the immersion chamber 301 away from the conveyor belt 201.

[0031] The process involves feeding zeolite slurry through a feeding pipe, shaping it at the outlet using a die, and then conveying it along a moving conveyor belt to form honeycomb zeolite strips. These strips are then cut into fixed-length honeycomb zeolite blocks (hereinafter referred to as zeolite) by a cutting blade. Dry, hot air is continuously supplied to the outer shell through an air supply pipe to accelerate the drying of the zeolite blocks. Once the zeolite blocks reach the other end of the conveyor belt, they are fully dried and fall into a storage chamber. Meanwhile, a catalyst compound solution from the soaking chamber enters the storage chamber through a metal mesh to soak the zeolite. The storage chamber is then transferred to a heating chamber by a traction rope. The zeolite material contains numerous pores, and after soaking, the catalyst compound solution remains within these pores. The solvent in the catalyst solution evaporates in the heating chamber, causing catalyst compounds to precipitate on the surface of the zeolite pores. Under high temperature, these catalyst compounds transform into stable catalysts that adhere to the surface of the zeolite's internal pores. After heating is complete, the traction rope pulls the storage chamber away from the heating chamber.

[0032] Example 2

[0033] Reference Figure 1 This is the second embodiment of the present invention. This embodiment differs from the first embodiment in that: multiple identical fixing rods 107 are fixedly installed at the end of the die head 103 furthest from the conveyor belt 201, with both ends of the fixing rods 107 fixed to the inner wall of the feeding pipe 101. A guide plate 108 is provided at the top of one end of the outer casing 105, which connects to the air supply pipe 104. An electric telescopic rod 109 is fixedly installed at the top of the cutting blade 106, and the other end of the electric telescopic rod 109 is fixedly installed on the upper surface inside the outer casing 105 surrounding the cutting blade 106. Four identical limiting blocks 110 are provided at the four corners of the cutting blade 106 on the outer casing 105.

[0034] The fixing rod is used to fix the die head at the outlet of the feeding pipe. The air guide plate is used to guide the gas delivered from the air supply pipe downward to the same height as the outlet, helping the zeolite to dry quickly. The electric telescopic rod extends and retracts continuously after being powered on, driving the cutting blade to move up and down to complete the cutting of the zeolite strips. The limiting block is used to restrict the position of the cutting blade, ensuring that it can only move up and down.

[0035] The remaining structure is the same as that in Example 1.

[0036] Example 3

[0037] Reference Figure 1This is the third embodiment of the present invention, which differs from the second embodiment in that: a guide plate 303 is provided at the bottom inner side of the soaking chamber 301, and a water inlet 304 is provided in the soaking chamber 301 near the top of the guide plate 303. A water outlet 305 is provided in the soaking chamber 301 near the bottom of the guide plate 303, and a switch 306 is provided in the soaking chamber 301 near one end of the conveyor belt 201. A water inlet channel 307 connected to the soaking chamber 301 is provided at the water inlet 304, and a water outlet channel 308 connected to the soaking chamber 301 is provided at the water outlet 305. A baffle 309 cooperating with the switch 306 is provided at the water inlet 307 at the water inlet 304, and a baffle 309 cooperating with the switch 306 is provided at the water outlet 308 at the water outlet 305.

[0038] The guide plate ensures water flows from the inlet to the outlet. During operation, a switch opens the inlet baffle and closes the outlet baffle. Sufficient catalyst compound solution is added to the soaking chamber through the inlet channel, and then the inlet baffle is closed. After multiple soaking batches, the outlet baffle is opened, and waste liquid flows out through the outlet channel to the waste liquid treatment equipment. Once all waste liquid has drained, the inlet baffle is opened again, and water flows into the soaking chamber through the inlet channel. Guided by the guide plate, water flows from the inlet to the outlet and finally into the waste liquid treatment equipment through the outlet channel, completing the cleaning of impurities at the bottom of the soaking chamber.

[0039] The remaining structure is the same as that in Example 2.

[0040] Example 4

[0041] Reference Figure 1 This is the fourth embodiment of the present invention. This embodiment differs from the third embodiment in that: a combustion chamber 310 is provided at the bottom of the heating chamber 302; an air inlet 311 is provided on one side of the water inlet channel 307 in the combustion chamber 310; and an air supply pipe 312 connected to the combustion chamber 310 is provided at the air inlet 311. A feeding port 313 is provided on one side of the combustion chamber 310 in the water outlet channel 308; and an air outlet 314 is provided at the top of the side of the combustion chamber 310 away from the soaking chamber 301; and an air outlet pipe 315 connected to the combustion chamber 310 is provided at the air outlet 314.

[0042] The combustion chamber is a heating chamber heated by a heat source. The feeding port is used to add fuel to the combustion chamber. The gas in the gas supply pipe enters the combustion chamber through the gas supply port to provide oxygen for combustion. The exhaust gas after combustion enters the exhaust pipe through the gas outlet and finally flows into the exhaust gas treatment equipment.

[0043] The remaining structure is the same as that in Example 3.
