Description

Technical Field

[0001] The utility model belongs to the technical field of delivery pumps, and in particular relates to a polyurea coating delivery pump. Background Art

[0002] Polyurea coating adopts a one-time coating process. No matter how large the area is, there are no joints. It is also a dust-free material polyurea coating with the characteristics of strong adhesion, friction resistance, and high hardness. In actual production, polyurea coating needs to be transported by a delivery pump.

[0003] In order to ensure the sealing effect of transmission, the existing conveying pump will set a sealing gasket at the connection position between the discharge port and the external pipeline. This kind of sealing gasket has a simple structure and mainly relies on its own deformation to increase the area to achieve sealing. However, it is prone to leakage due to aging in long-term use. At the same time, it is easy to deviate or fall off during installation. Therefore, it has great limitations in actual use and there is room for improvement. Utility Model Content

[0004] The utility model aims to provide a polyurea coating delivery pump to solve the problem that the existing delivery pumps mentioned in the above background technology have poor sealing effect and are prone to leakage during use.

During use, a negative pressure is formed inside the discharge pipe by the air pump to absorb the polyurea coating and then discharge it from the discharge end; it also includes a sealing component; specifically, a sealing sleeve having connecting ring grooves symmetrically provided at both ends, wherein the connecting ring groove sleeve at one end is arranged at the end of the discharge pipe; an air bag is placed in the connecting ring groove and abutted against the end face of the discharge pipe. When the discharge pipe is connected to the sealing sleeve, the discharge pipe will press against the air bag and force the air bag to deform. The deformed air bag will completely fill the gap between the discharge pipe and the sealing sleeve, thereby improving the sealing effect.

[0006] Preferably, a double-sided tape is bonded to the inner end surface of the connecting ring groove, and the double-sided tape is bonded to the airbag, thereby achieving connection and installation of the airbag and preventing the airbag from moving arbitrarily in the connecting ring groove.

[0007] Preferably, a threaded portion is formed at the end opening of the discharge pipe, and the threaded portion is threadedly connected to the inner wall of the connecting ring groove, thereby achieving a stable connection without separation. At the same time, during rotation, the airbag can be continuously pressed tightly to force the airbag to deform, and the external pipe will be connected to the internal thread of the connecting ring groove at the other end, and will also press tightly against the airbag to achieve sealing of the connection.

[0008] Preferably, the sealing assembly also includes an inner ring fixed to the inner wall of the discharge pipe, one end of the inner ring extends toward the inner wall of the sealing sleeve, and the inner wall of the inner ring abuts against the inner wall of the sealing sleeve, thereby achieving further sealing, thereby completing the inner and outer wrapping seal of the connection between the sealing sleeve and the discharge pipe.

[0009] Preferably, the bottom end of the discharge pipe is connected with a connecting pipe for directly contacting the polyurea coating, and a support column is installed in a ring shape between the connecting pipe and the top end of the discharge pipe to improve the overall strength.

[0010] Preferably, the outside of the support column is also provided with a limiting ring and an adjusting ring, and the inner sides of the limiting ring and the adjusting ring are provided with grooves that snap into the outside of the support column, thereby achieving a stable installation and allowing all the support columns to form a whole.

[0011] Preferably, placement grooves are provided at both ends of the adjustment ring, and connecting end plates that are inserted into the placement grooves are fixed at both ends of the limiting ring. The connecting end plates and the placement grooves are fixed by bolts passing through them, thereby achieving a stable connection between the two, and can also be disassembled and assembled. Compared with a fixed structure, this structure is more flexible in use.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The designed sealing component can fully wrap the end of the discharge pipe and realize multiple seals. Compared with the sealing performance of a single sealing gasket, the sealing component is threadedly connected to the discharge pipe to ensure installation stability and anti-dislocation, thereby improving the shortcomings of the existing structure in use.
