[0031] As Figures 1-3As shown in the figure, a high-temperature isolator for a diaphragm pump includes a high-temperature section pipeline 600. A low-temperature section pipeline 100 is installed on the outer wall of one side of the high-temperature section pipeline 600, and the high-temperature section pipeline 600 is communicated with the low-temperature section pipeline 100. An isolator body 300 is arranged inside the low-temperature section pipeline 100, and the isolator body 300 is installed on the outer wall of a guide rod 400. The guide rod 400 is mainly used to guide the movement of the isolator body 300. First buffer pads 200 and second buffer pads 500 are respectively arranged on both sides of the outer wall of the guide rod 400. The first buffer pads 200 are installed on the outer wall of one side of a first connecting plate 101, and the second buffer pads 500 are installed at one end of a spring 700, and the other end of the spring 700 is installed on the end wall of one end of a mounting block 801. The first buffer pads 200 and the second buffer pads 500 made of metal rubber composite can protect the brittle material silicon carbide wear-resistant guide sleeves 304 from cracking due to collision impact, and extend the service life of the isolator body 300;

[0032] A mounting sleeve 305 is arranged on the isolator body 300. Gland covers 302 are installed on the end walls at both ends of the mounting sleeve 305, and buffer rubber 303 is vulcanized on the outer walls of the gland covers 302. The buffer rubber 303 is vulcanized on the gland covers 302. A collision is formed between the buffer rubber 303 and the first buffer pads 200 or the second buffer pads 500, and the rubber absorbs the impact energy. Further, it can protect the brittle material silicon carbide wear-resistant guide sleeves 304 from cracking due to collision impact, and extend the service life of the isolator body 300. Silicon carbide wear-resistant guide sleeves 304 are arranged on both sides of the inner wall of the mounting sleeve 305. Four groups of rubber sheets 301 are arranged in a rectangular array on the outer wall of the mounting sleeve 305. The arrangement of the four groups of rubber sheets 301 is used to slow down the heat exchange.

[0033] One end of the guide rod 400 is installed on the outer wall of one side of the first connecting plate 101, and the first connecting plate 101 is installed on the inner wall of the low-temperature section pipeline 100. The other end of the guide rod 400 extends into the high-temperature section pipeline 600, passes through the through hole in the end wall of the mounting block 801 and is connected to a second connecting plate 603.

[0034] The mounting block 801 is installed inside the connecting sleeve 800, and the connecting sleeve 800 is installed on one side outer wall of the second connecting plate 603. The second connecting plate 603 is arranged on one side inside the discharge port 602. The discharge port 602 is opened on the other side outer wall of the high-temperature section pipeline 600. And a shock-absorbing buffer rubber ring 604 is arranged at the connection between the second connecting plate 603 and the high-temperature section pipeline 600. The setting of the shock-absorbing buffer rubber ring 604 can play a role in buffering and shock-absorbing the force transmitted to the second connecting plate 603 by the guide rod 400. The top of the high-temperature section pipeline 600 is provided with a feed port 601. Due to the settings of the feed port 601 and the discharge port 602, the high-temperature slurry enters the high-temperature section pipeline 600 from the feed port 601 and is discharged from the discharge port 602.

[0035] One-way valves are arranged on both the feed port 601 and the discharge port 602. The setting of the one-way valves avoids the occurrence of the situation where the high-temperature slurry flows back at the feed port 601 or the discharge port 602.

[0036] A section area of the guide rod 400 is located inside the spring 700, and a section area of the guide rod 400 is located inside the mounting sleeve 305.

[0037] The other end of the low-temperature section pipeline 100 is provided with a pump connection port 102, and the pump connection port 102 is communicated with a diaphragm pump through a cooling pipeline. The cooling pipeline mainly cools the propelling liquid, avoiding the situation that the service life of the rubber diaphragm on the diaphragm pump is affected due to the increase in the temperature of the propelling liquid.

[0038] During use, the pump connection port 102 is communicated with the diaphragm pump through the cooling pipeline. When the diaphragm pump starts to work, water is used as the propelling liquid in the low-temperature section pipeline 100. After working for a period of time, high-concentration slurry is mixed in and becomes low-concentration slurry. At the feed port 601, a low-pressure feeding pump feeds auxiliary material to the feed port 601. When the diaphragm pump starts, the rubber diaphragm on the diaphragm pump drives the low-temperature material to reciprocate in the pipeline, thereby driving the isolator body 300 to reciprocate in the low-temperature section pipeline 100 and then performing high-temperature material transportation. Thus, the high-temperature slurry enters the high-temperature section pipeline 600 from the feed port 601 and is discharged from the discharge port 602. Therefore, the present utility model uses the reciprocating isolator body 300 to isolate the high-temperature material, reduces the temperature of the diaphragm pump chamber, avoids the influence of high temperature on the rubber diaphragm of the diaphragm pump, reduces the aging speed of the diaphragm rubber caused by high temperature, thereby the present utility model prolongs the service life of the key component rubber diaphragm of the diaphragm pump, extends the maintenance period of the diaphragm pump, reduces the shutdown time of the diaphragm pump due to maintenance, and reduces costs and increases benefits.

[0039] The above are only the preferred embodiments of the present utility model and are not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
