Therefore, an anti-blocking nozzle is provided.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide an anti-blocking nozzle which can effectively solve the problems in the background technology.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the utility model provides an anti-blocking type spouts mouth, includes retainer plate, screw thread A and clean hole, the retainer plate bottom is provided with the connecting pipe, the import has been seted up to the connecting pipe bottom, the import inboard is equipped with the clamping ring, clamping ring inboard is provided with the filter screen, the retainer plate top is provided with penetrates the way, penetrate and say that peripheral cover is equipped with the leak protection sleeve pipe.

Furthermore, the bottom of the inner wall of the leakage-proof sleeve is provided with a thread B, the leakage-proof sleeve is connected with the thread A through the thread B, and the top of the inner wall of the leakage-proof sleeve is adhered with a sealing ring B corresponding to the top of the cleaning hole; the sealing ring B is used for ensuring the sealing performance of the periphery of the jet channel during operation.

Further, the filter screen is made of stainless steel materials, a sealing ring A is adhered to the periphery of the clamping ring, and the clamping ring is clamped and fixed on the inner side of the inlet through the sealing ring A; the filter screen is used for blocking caking in materials during operation, so that the blockage caused by the caking in the materials entering the nozzle is avoided.

Further, the screw thread A is arranged at the bottom of the periphery of the injection passage, and the cleaning holes are uniformly formed in the periphery of the injection passage and located at the top of the screw thread A.

Compared with the prior art, the utility model has the following beneficial effects:

1. through setting up sealing washer A, clamping ring and filter screen, utilize sealing washer A to block in the import with reserve clamping ring card to utilize the inboard filter screen of clamping ring to block the caking in the material at the during operation, avoid it to get into and penetrate the mouth inside and cause the jam, thereby promoted the anti-clogging nature by a wide margin.

2. Through setting up screw thread A, screw thread B and clean hole, utilize screw thread B and screw thread A separation to dismantle the leak protection sleeve pipe, see through clean hole jet passage inner wall and wash to promote and maintain the convenience.

Detailed Description

In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.

As shown in fig. 1-4, an anti-blocking type nozzle comprises a fixing ring 1, a thread A8 and a cleaning hole 9, wherein a connecting pipe 2 is arranged at the bottom end of the fixing ring 1, an inlet 3 is formed in the bottom of the connecting pipe 2, a clamping ring 4 is arranged on the inner side of the inlet 3, a filter screen 5 is arranged on the inner side of the clamping ring 4, a jet channel 7 is arranged at the top end of the fixing ring 1, and a leakage-proof sleeve 10 is sleeved on the periphery of the jet channel 7.

Wherein, leak protection sleeve pipe 10 inner wall bottom is provided with screw thread B11, leak protection sleeve pipe 10 passes through screw thread B11 and connects in screw thread A8, the sticky sealing washer B12 that is equipped with in the corresponding clean hole 9 top in leak protection sleeve pipe 10 inner wall top.

In the embodiment, as shown in fig. 1, 2 and 4, the leakage-proof sleeve 10 is conveniently disassembled and assembled through the thread A8 and the thread B11.

The filter screen 5 is made of stainless steel, a sealing ring A6 is adhered to the periphery of the clamping ring 4, and the clamping ring 4 is clamped and fixed on the inner side of the inlet 3 through a sealing ring A6.

In this embodiment, as shown in fig. 1, 2 and 3, the filter screen 5 is used to block the agglomerates in the material, so as to prevent the agglomerates from entering the nozzle to cause blockage.
