Description

Technical Field

[0001] This utility model relates to a granular fire-retardant coating spraying machine, belonging to the technical field of spraying equipment. Background Technology

[0002] Currently, almost all spray painting machines produced domestically and internationally require high-pressure extrusion output, but granular paint cannot be sucked in for spraying. Existing spray painting machines have complex structures and are heavy, failing to achieve portable performance. Furthermore, the plunger booster block in the granulation pump is almost entirely made of metal, which not only incurs high processing costs and is prone to wear, but also further increases the overall weight. Additionally, existing granulation pumps almost universally use three-way inlet and outlet designs, such as... Figure 6 As shown, the pump suction effect needs to be further improved, and it also needs to be used in conjunction with a material bucket.

[0003] In view of this, this utility model is proposed. Utility Model Content

[0004] To address the aforementioned technical problems in the prior art, the purpose of this utility model is to provide a particulate fire-retardant coating spraying machine. By adding a transition body, it can be used in a direct suction manner, which greatly improves the pump suction efficiency. Furthermore, the use of a plastic plunger pressure booster block reduces the overall weight and lowers the cost.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution:

[0006] A granular fire-retardant coating spraying machine includes an upper pump seat, a cylinder, a plunger rod, and a plunger body. The plunger rod and plunger body are both located inside the cylinder. The upper pump seat is connected to the end of the cylinder. A pressure booster seat is connected to the end of the cylinder away from the upper pump seat. A plunger pressure booster block is connected to the end of the plunger body away from the plunger rod. The upper pump seat includes an upper pump body and a base connected to each other. The plunger body is sleeved on the outside of the upper pump body. A transition body is provided between the plunger body and the base. The outer diameter of the transition body is equal to the outer diameter of the plunger body and larger than the outer diameter of the base.

[0007] The plunger booster block is a plastic plunger booster block.

[0008] The plunger body is composed of several plunger plates, and the several plunger plates are sleeved on the upper pump seat.

[0009] Both the plastic plunger booster block and the base are provided with connection holes, and the connection between the plastic plunger booster block and the base is achieved by inserting screws into the connection holes.

[0010] The plunger plate has a downward groove, and several plunger plates are stacked in the groove. A gasket is placed in the groove of the first plunger plate, and the several plunger plates are pressed on the top of the transition body by a clamping nut to form a plunger body. The upper edge of the last plunger plate is a certain distance from the upper edge of the transition body.

[0011] The upper pump body has an external thread at its end, and the inner side of the clamping nut has an internal thread, which engages with the external thread.

[0012] The outer wall of the clamping nut is provided with several equally spaced slots.

[0013] The granular pump requires the installation of a valve body, which is mounted at the bottom of the booster seat to form a direct-suction vacuum negative pressure slurry granular pump.

[0014] The granular fire-retardant coating spraying machine of this utility model has the following beneficial effects:

[0015] 1. This utility model provides a transition body between the plunger body and the base. The outer diameter of the transition body is equal to the outer diameter of the plunger body and larger than the outer diameter of the base. This structure allows the utility model to be used in a direct suction mode, which greatly improves the pumping efficiency compared with the side suction mode in the prior art. It also eliminates the need for an additional material tank and reduces costs.

[0016] 2. The plunger booster block in this utility model is made of plastic, which not only reduces the overall weight but also improves the wear resistance of the plunger booster block, thereby extending its service life and reducing production costs.

[0017] 3. The plunger plate in this utility model has a downward groove, and several plunger plates are stacked in the groove. A gasket is placed in the groove of the first plunger plate, and the several plunger plates are pressed on the top of the transition body by the clamping nut to form a plunger body.

Detailed Implementation

[0025] The present invention will be further described below with reference to specific embodiments, but the scope of protection of the present invention is not limited thereto.

[0026] like Figure 1-5 As shown, the granular fire-retardant coating spraying machine of this utility model includes an upper pump seat 1, a cylinder 2, a plunger rod 3, and a plunger body 4. Both the plunger rod 3 and the plunger body 4 are located inside the cylinder 2. The upper pump seat 1 is connected to the end of the cylinder 2. A pressure booster seat 5 is connected to the end of the cylinder 2 away from the upper pump seat 1, and a plunger pressure booster block 6 is connected to the end of the plunger body 4 away from the plunger rod 3. Existing granular pumps use a side-suction method, such as... Figure 6 As shown, the pressure booster seat 5 has an outlet and an inlet on its left and right sides, and the valve body 13 is installed on the outlet and inlet to form a three-way valve.

[0027] Preferably, the upper pump seat 1 of this invention includes an upper pump body 11 and a base 12 connected to each other. A plunger body 4 is sleeved on the outside of the upper pump body 11. A transition body 7 is provided between the plunger body 4 and the base 12. The outer diameter of the transition body 7 is equal to the outer diameter of the plunger body 4 and larger than the outer diameter of the base 12. This structure allows the invention to be used in a manner that... Figure 5 The direct-suction type shown is formed by installing the valve body 13 at the bottom of the booster seat 5 to form a direct-suction vacuum negative pressure mud particle pump, which greatly improves the pump suction efficiency and reduces costs by eliminating the need for an additional material tank.

[0028] Furthermore, the plunger booster block 6 in this invention is a plastic plunger booster block. Both the plastic plunger booster block and the base 12 are provided with connecting holes 61. The connection between the plastic plunger booster block and the base 12 is achieved by inserting screws 8 into the connecting holes 61. In this invention, changing the plunger booster block 6 from metal to plastic not only reduces the overall weight but also improves the wear resistance of the plunger booster block 6, thereby extending its service life and reducing production costs.

[0029] Furthermore, the plunger body 4 in this invention is composed of several plunger plates 41, and the several plunger plates 41 are sleeved on the upper pump body 11 of the upper pump seat 1. Preferably, the plunger plates 41 are provided with downward grooves 411, the several plunger plates 41 are stacked in the grooves 411, and a gasket 9 is provided in the groove 411 of the first plunger plate 42. The upper pump body 11 has an external thread 111 at its end, and the inner side of the clamping nut 10 has an internal thread 101. The internal thread 101 meshes with the external thread 111, that is, the clamping nut 10 presses several plunger pieces 41 on top of the transition body 7 to form a plunger body 4. The upper edge of the last plunger piece 43 is a certain distance from the upper edge of the transition body 7. Furthermore, the outer wall of the clamping nut 10 has several slots 102 at equal intervals for engaging with the inner wall of the cylinder 2, which greatly improves the stability of the plunger body 4 during use. The length of the plunger body 4 can be adjusted by increasing or decreasing the number of plunger pieces 41, further improving the versatility of the product.

[0030] The other structures and connections of this utility model are the same as those of the utility model patent with announcement number CN221003030U, and will not be described in detail here.

[0031] The addition of the transition body 7 allows for direct suction during use, greatly improving pumping efficiency. Furthermore, the use of the plastic plunger booster block 6 reduces the overall weight and lowers costs.

[0032] The above embodiments are only used to explain the inventive concept of this utility model, and are not intended to limit the protection of this utility model. Any non-substantial modifications made to this utility model using this concept should fall within the protection scope of this utility model.
