Embodiment 1

[0022] The present invention discloses a temperature control device for slurry transmission. The mixed (consistent viscosity) slurry is placed in a storage tank 4, transported by a screw pump 5 and reaches the spraying die 4 for spraying. The temperature control device Installed on the slurry delivery pipeline between the screw pump 5 and the spraying die 4, the temperature of the slurry in the delivery pipeline is kept constant through the heat exchange of the circulating fluid during the flow of the slurry through the temperature control device.

[0023] The temperature control device includes a heat exchanger 1 and a temperature control cabinet 2 .

[0024] The temperature control cabinet 2 is provided with a circulating fluid accommodation chamber (not shown) and a temperature controller, the circulating fluid accommodation chamber holds the circulating fluid, and the temperature controller is used to precisely control the temperature of the circulating fluid. The temperat...

Embodiment 2

[0030] The difference from Embodiment 1 is that the middle part of the inner pipe 11 has a mandrel 15 arranged in the axial direction, and the periphery of the mandrel 15 has thorn-shaped structures 16 evenly distributed. The height of the thorn structure 16 is greater than or equal to the height of the helical structure 14, specifically, the sum of the height of the thorn structure 16 and the height of the helical structure 14 is less than or equal to the mandrel 15 to the The distance between the inner wall surfaces of the inner pipe 11 is described.

[0031] In this embodiment, through the design of the spiral structure in the inner pipe and the mandrel, the heat transfer area between the slurry and the circulating fluid is increased, the heat transfer efficiency is improved, and the heat exchange inside the slurry is further enhanced, thereby During the circulation of the slurry, the temperature at different positions of the pipeline is kept consistent, so as to control th...

Abstract

The invention discloses a temperature control device for slurry conveyance. The temperature control device is mounted on a slurry conveyance pipeline between a screw pump and a die head, slurry and circulating liquid suffer from heat exchange when the slurry flows through the temperature control device, and the temperature of the slurry in the conveyance pipeline is constant. The temperature control device for slurry conveyance is novel in concept, the temperature control device is mounted between the screw pump and the die head, the slurry on the conveyance pipeline and the circulating liquidsuffer from heat exchange in the temperature control device, thus, the temperature of the slurry in the conveyance process is kept consistent, the viscosity and the temperature of the slurry in the conveyance process are guaranteed, and the consistency of slurry coating is greatly improved.

Description

technical field [0001] The invention relates to the field of slurry mixing, in particular to a temperature control device for slurry transmission. Background technique [0002] Automotive battery coating is to mix active materials, conductive agents, binders, dispersants, etc. according to a certain ratio to make a slurry, which is evenly sprayed on the outer surface of the battery through a die. During the spraying process, the viscosity of the slurry directly affects the consistency of the surface density of the slurry coating, thereby affecting the performance of the battery. However, under the premise of certain other external factors, temperature is a major factor affecting the viscosity of slurry, and changes in slurry temperature usually lead to changes in viscosity. [0003] After the slurry is evenly mixed, it usually needs to be output from the storage tank through a screw pump, and then transported to the die head through a pipeline for spraying. In the existing...
