Description

Technical Field

[0001] The utility model relates to the technical field of fluidized bed cleaning, in particular to a fluidized bed cleaning device. Background Art

[0002] Fluidized bed technology is a technique for keeping granular solid materials suspended in a gas or liquid flow. It is commonly used in processes such as chemical reactions, particle drying, and heat exchange. After granulation or coating, the fluidized bed needs to be cleaned after each process because the materials and droplets required for each process product are different.

[0003] Some existing cleaning equipment, such as a wet granulator with a cleaning-in-place system (patent number CN102698651B), has a pump station used to provide clean water and compressed air to the cleaning-in-place (CIP) system. The pipes for the purified water source and the tap water source are connected to a main pipe, which is equipped with a booster pump. The compressed air pipe is connected to the main pipe and is located behind the water booster pump. There is a blind spot when drying the pipe. Utility Model Content

[0004] The purpose of the utility model is to provide a fluidized bed cleaning device, which solves the problem of drying blind spots in the cleaning devices in the prior art.

[0005] The utility model is implemented as follows: a fluidized bed cleaning device comprises a movable frame and a first liquid inlet mechanism, a blowing mechanism, a pump body, a second liquid inlet mechanism, a cleaning mechanism and a discharge mechanism arranged on the frame; the cleaning mechanism is used to be connected to the equipment to be cleaned, the cleaning mechanism is placed between the pump body and the discharge mechanism, the first liquid inlet mechanism is used to be connected to an external liquid supply device, the first liquid inlet mechanism is connected to the cleaning mechanism through the pump body, the second liquid inlet mechanism is connected to the cleaning mechanism, and the blowing mechanism is connected to the cleaning mechanism through the pump body.

[0006] The first liquid passes through the first liquid inlet mechanism and the pump body in sequence and enters the cleaning mechanism to clean the fluidized bed; the second liquid passes through the second liquid inlet mechanism and enters the cleaning mechanism to clean the fluidized bed; the order of the first liquid and the second liquid is adjusted according to actual conditions. After the fluidized bed is cleaned, the first liquid inlet mechanism and the second liquid inlet mechanism need to be blown dry to ensure cleanliness; in the utility model, the first liquid inlet mechanism is connected to the pump body, and the blowing mechanism is connected to the pump body. When the blowing mechanism is started, both the pump body and the first liquid inlet mechanism can be blown dry; at the same time, when the blowing mechanism starts to blow, the gas can enter the subsequent second liquid inlet mechanism and the cleaning mechanism from the pump body for blowing dry. Compared with the prior art in which the blowing mechanism is directly connected to the cleaning mechanism, the blowing mechanism of the utility model can blow dry the pipe through which the liquid passes without dead angles.

[0007] A further technical solution of the present invention is: the first liquid inlet mechanism includes a branch pipe and a main pipe connected to the branch pipe, the branch pipe is provided with a first liquid inlet valve, and the main pipe is provided with a one-way valve.

[0008] The branch pipe can be connected to tap water and purified water as needed. Cleaning with tap water first and then with purified water can reduce the consumption of purified water and reduce costs.

[0009] A further technical solution of the present invention is: the air blowing mechanism includes an air blowing pipeline and a gas compression purification device, the gas compression purification device is connected to the air blowing pipeline, and the air blowing pipeline is connected to the cleaning mechanism through a pump body.

[0010] Gas compression and purification equipment is used to compress and purify the gas, and then blow the compressed purified gas through the blowing pipe to dry the cleaning equipment.

[0011] A further technical solution of the present utility model is: the second liquid inlet mechanism includes a liquid storage tank, a second liquid inlet pump and a second liquid inlet pipe, the second liquid inlet pump is connected to the liquid storage tank, the liquid outlet end of the second liquid inlet pump is connected to the second liquid inlet pipe, and the liquid outlet end of the second liquid inlet pipe is connected to the cleaning mechanism.

[0012] The second liquid enters the second liquid inlet pipe from the liquid storage tank through the second liquid inlet pump, and then enters the cleaning mechanism to clean the fluidized bed.

[0013] A further technical solution of the present utility model is: the cleaning mechanism includes a mixing pipe and multiple outlet pipes placed on the mixing pipe, the outlet pipe is provided with a cleaning valve, the outlet pipe is used to connect with the equipment to be cleaned, one end of the mixing pipe is connected to the pump body and the other end is connected to the discharge mechanism, and the second liquid inlet mechanism is connected to the mixing pipe.

[0014] When the cleaning liquid needs to be mixed with water, the first liquid inlet mechanism and the second liquid inlet mechanism are started at the same time. The first liquid and the second liquid enter the mixing pipe in the cleaning mechanism and mix, and then enter the fluidized bed through the outlet pipe. The design of multiple outlet pipes facilitates the cleaning of multiple cavities in the fluidized bed.

[0015] A further technical solution of the present invention is: the discharge mechanism includes a discharge pipe and a discharge valve disposed on the discharge pipe, and the discharge pipe is connected to the cleaning mechanism.

[0016] The liquid in the pipeline is first discharged through the discharge pipe and then blown dry, which is more efficient.

[0018] The first liquid inlet mechanism requires external equipment, and the air blowing mechanism also needs to be connected to the pipe. Since the second liquid inlet pump has a bottom-in and top-out structure, considering the rationality of the design and convenient operation, the first liquid inlet mechanism, the air blowing mechanism and the second liquid inlet pump are placed on the first rack; the discharge mechanism is located at a low position to facilitate the discharge of the cleaned liquid from the cleaning equipment. The cleaning mechanism can utilize the gravity of the liquid on the second rack to reduce energy consumption. The structure of the second liquid inlet pump makes it more reasonable to place the liquid storage tank on the second rack, which takes up less space. Therefore, the design of the second mechanism also takes into account rationality and energy consumption.

[0019] A further technical solution of the present invention is: a storage box is provided on the first frame, and an electric control cabinet is provided on a side of the frame away from the first liquid inlet mechanism.

[0020] The storage box is used to store tools and pipelines, etc., which are easy to take out on the first rack. The position of the electric control cabinet does not affect the pipe connection.

[0021] A further technical solution of the present invention is that a wiring trough is provided on the second frame.

[0022] The cable trough is used to secure air pipes and cables. The second rack is located below the first rack, which prevents the air pipes and cables from being pulled.

[0023] The beneficial effects of the present invention are as follows: the first liquid passes through the first liquid inlet mechanism and the pump body in sequence and enters the cleaning mechanism to clean the fluidized bed; the second liquid passes through the second liquid inlet mechanism and enters the cleaning mechanism to clean the fluidized bed; the order of the first liquid and the second liquid is adjusted according to actual conditions, and after the fluidized bed is cleaned, the first liquid inlet mechanism and the second liquid inlet mechanism need to be blown dry to ensure cleanliness; in the present invention, the first liquid inlet mechanism is connected to the pump body, and the blowing mechanism is connected to the pump body, and when the blowing mechanism is started, both the pump body and the first liquid inlet mechanism can be blown dry; at the same time, when the blowing mechanism starts to blow, the gas can enter the subsequent second liquid inlet mechanism and the cleaning mechanism from the pump body for blowing dry.
