Description

Technical Field

[0001] This utility model relates to the field of sodium carboxymethyl cellulose production technology, and in particular to a condensation device for sodium carboxymethyl cellulose. Background Technology

[0002] Sodium carboxymethyl cellulose is an organic compound, a carboxymethylated derivative of cellulose, and the most important ionic cellulose gum. Sodium carboxymethyl cellulose is usually produced by reacting natural cellulose with caustic alkali and monochloroacetic acid. It is an anionic polymer compound. Sodium carboxymethyl cellulose is a white fibrous or granular powder, odorless, tasteless, hygroscopic, and easily dispersed in water to form a transparent colloidal solution.

[0003] Sodium carboxymethyl cellulose requires different processing steps during production. These processes necessitate the use of condensing devices to cool the raw materials. Application No. CN202221466071.7 proposes a condensing device for sodium carboxymethyl cellulose production to cool the raw materials during processing. However, this device, along with most other cooling equipment, uses serpentine tubes for condensation, which have limited surface area, resulting in limited heat exchange and cooling capacity. Furthermore, the water tank itself does not have heat dissipation capabilities and must be connected to a circulating cooling water system to maintain the water cooling effect. Summary of the Invention

[0004] To improve the cooling efficiency during the processing of sodium carboxymethyl cellulose (CMC) and eliminate the need for an external cooling water system, this invention proposes a condensation device for CMC, comprising: a feeding device, a condensation chamber, a water tank, and condensation pipes. The water tank is a split type, located above and below the condensation chamber. The condensation chamber contains a stirring paddle driven by a stirring motor. A feeding inlet is located on one side of the condensation chamber, and the feeding device connects to the inlet. Two opposite sides of the condensation chamber are equipped with a diverter pipe and a collector pipe. The inlet end of the diverter pipe connects to the upper water tank and a booster pump is installed on the connecting pipe. It also connects to several condensation pipes located within the condensation chamber. The outlet end of the collector pipe connects to the lower water tank, and the inlet end connects to several condensation pipes. The condensation pipes do not obstruct the continuous rotation of the stirring paddle. The lower water tank has a channel for unloading from the condensation chamber and a valve for opening and closing this channel in the middle.

[0005] Preferably, the condenser tube comprises: a ring-shaped main body, an outer ring tube on the outer circumference of the main body, an inner ring tube on the inner circumference of the main body, the main body having an inner cavity and multiple through holes, each through hole not communicating with the inner cavity of the main body; multiple water holes are provided on the inner circumference of the outer ring tube and the outer circumference of the inner ring tube, all of which communicate with the inner cavity of the main body; the outer circumference of the outer ring tube is also provided with two support tubes communicating with the inner cavity of the outer ring tube; the support tubes are respectively connected to the diverter tube and the collector tube, and the inner ring tube is sleeved on the outside of the main shaft of the agitator.

[0006] Preferably, the support tube has an external thread.

[0007] Preferably, the main body is made of aluminum alloy or stainless steel.

[0008] Preferably, the surface of the body is rough or has multiple protruding structures.

[0009] Preferably, the water tank includes: a water storage tank, a heat dissipation tank, a water pump, and a spray pipe; the heat dissipation tank is located above the water storage tank, the spray pipe is installed on one side of the heat dissipation tank, and several atomizing nozzles on the spray pipe are located inside the heat dissipation tank; one end of the water pump is connected to the water storage tank, and the other end is connected to the spray pipe; a water collector is provided on the top of the heat dissipation tank, and a water inlet pipe is provided on one side of the upper part; a drain pipe is provided on one side of the bottom of the water storage tank, and the upper surface is recessed downward in the middle and has a clearance hole that runs vertically through it; both the water storage tank and the heat dissipation tank are also provided with connecting pipes for connecting external water collection pipes and booster pumps; a waterproof and breathable membrane is fixed on the top of the water collector; the spray pipe is tubular or strip-shaped, and has a water inlet and multiple atomizing nozzles, with the water inlet connected to the water pump; both the water inlet pipe and the water outlet pipe are equipped with flow control valves.

[0010] This invention replaces the commonly used serpentine condenser tube with a ring-shaped condenser tube. Cooling water flows from the support tube into the outer ring tube, then exchanges heat with a large number of heat sources in the inner cavity of the main body and the inner ring tube, and finally exits through the support tube on the other side. The condenser tube of this device has a larger surface area than ordinary serpentine condenser tubes under the same material and weight, resulting in higher cooling efficiency. In addition, the water tank of this device is set in an upper and lower split type, each performing different functions. The heat dissipation water tank located at the top can complete the heat dissipation function well, without the need to continuously supply cooling water to the water cooling device or connect an external circulating cooling water system. This invention has a small footprint, low cost, and can improve production efficiency. Attached Figure Description
