Description

Technical Field

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

[0002] In modern manufacturing and construction, slurry spraying technology is widely used in the application of materials such as coatings, adhesives, and mortars. These applications place high demands on spraying quality and efficiency. However, existing slurry spraying equipment presents several pressing challenges, directly impacting spraying effectiveness and economic efficiency.

[0003] Specifically, slurries often settle and stratify within storage tanks due to prolonged standing and the effects of gravity. This settling can not only lead to uneven slurry concentration during spraying, thus affecting the quality of the sprayed coating, but can also cause blockage at the nozzle inlet, impacting proper operation. Furthermore, to address this settling issue and ensure spray quality, traditional spray equipment often employs complex and expensive nozzle designs that require agitation or high-pressure spraying, which undoubtedly increases production and maintenance costs. Utility Model Content

[0004] The utility model aims to provide a slurry spraying device which can effectively reduce the sedimentation and stratification of slurry in a storage tank during the spraying process.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a slurry spraying device, which includes a storage tank for storing slurry, a nozzle connected to one end of the storage tank is provided, and the nozzle is used to receive the slurry in the storage tank and spray the received slurry onto a target surface. A vibrator is also provided on the storage tank, and the vibrator is used to provide vibration waves to the storage tank so that the slurry in the storage tank is in a vibrating state.

[0006] Preferably, the vibration wave output by the vibrator includes ultrasonic waves.

[0007] Preferably, the vibrator is arranged on the end surface of the storage tank connected to the nozzle.

[0008] Preferably, the storage tank is further provided with a cooling element for cooling the slurry.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Figure 1 This is a schematic diagram of the original structure of the slurry spraying device in an embodiment of the present utility model. DETAILED DESCRIPTION

[0015] In order to explain the technical content, structural features, achieved objectives and effects of the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0016] This embodiment discloses a slurry spraying device for performing a slurry spraying operation to spray the slurry onto a target working surface. For example, in the manufacturing process of a fuel cell, the required slurry is sprayed onto a membrane electrode.

[0017] like Figure 1 The slurry spraying device includes a storage tank 1 for storing slurry, and a nozzle 2 is provided at one end of the storage tank 1 and is connected thereto. The nozzle 2 is used to receive the slurry in the storage tank 1 and spray the received slurry onto the target surface. The storage tank 1 is also provided with a vibrator 3, and the vibrator 3 is used to provide vibration waves to the storage tank 1 so that the slurry in the storage tank 1 is in a vibrating state.

[0018] The slurry spraying device disclosed in this embodiment is provided with a vibrator 3 capable of emitting vibration waves on the storage tank 1. The vibration waves emitted by the vibrator 3 keep the slurry in the storage tank 1 in a constant vibrating state, effectively preventing the sedimentation and stratification of the slurry and ensuring the uniformity and continuity of the slurry during the spraying process. This spraying device not only improves the spraying quality and reduces the risk of clogging of the nozzle 2, but also simplifies the design of the nozzle 2, thereby reducing the production and maintenance costs of the equipment and improving the economy and reliability of the overall spraying device.

[0019] On the other hand, the vibration wave output by the vibrator 3 includes ultrasonic waves. When the slurry spraying device is used for spraying, the ultrasonic waves emitted by the vibrator 3 are transmitted to the slurry in the storage tank 1, causing the slurry to be in a peristaltic state.

[0020] Furthermore, the vibrator 3 is provided on the end surface of the storage tank 1 connected to the nozzle 2, thereby ensuring that at least the slurry near the nozzle 2 is in a peristaltic state to avoid slurry sedimentation.

[0021] In addition, the real-time vibration of the slurry will also cause the temperature to rise. If it is not restricted, it will affect the quality of the slurry. In this regard, the storage tank 1 is also provided with a cooling member 4 for cooling the slurry to prevent the temperature of the slurry from being too high.

[0022] Furthermore, the cooling element 4 includes a cooling coil 4, the inlet and outlet joints of which are connected to a cooling medium circulation supply device 7 located outside the storage tank 1. During use of the slurry spraying device, a cooling medium is supplied to the cooling coil 4 and circulated, and heat exchange occurs between the cooling medium and the slurry in the storage tank 1 to absorb the temperature in the slurry, thereby cooling the slurry.

[0023] Specifically, the cooling coil 4 is arranged in the storage tank 1 at one end close to the vibrator 3, so that the power of the vibrator 3 can be reduced to the maximum extent, so that the slurry entering the nozzle 2 is in a completely mixed state.

[0024] On the other hand, the storage tank 1 is further provided with a temperature sensor 5 located near the cooling coil 4. The flow rate of the cooling medium in the cooling coil 4 changes dynamically according to the detection value of the temperature sensor 5. In this embodiment, the controller of the cooling medium circulation supply device 7 is connected to the temperature sensor 5. In this way, the flow rate of the cooling medium in the cooling coil 4 can be dynamically adjusted according to the dynamic changes in the temperature of the slurry, thereby effectively controlling the temperature of the slurry to be within the target range.

[0025] On the other hand, the nozzle head 2 is provided with an atomizing structure for atomizing the slurry so that the nozzle head 2 sprays the slurry in an atomized state. Specifically, the nozzle head 2 is also provided with an air source connector 6, and the compressed gas received by the air source connector 6 drives the atomizing structure on the nozzle head 2 to work.

[0026] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope covered by the present invention.
