Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0021] As shown in Figures 1 to 4 The present application provides a heat insulating device, which comprises a sliding member 1, a connecting member 2, two baffles 3 and a plurality of heat insulating diaphragms 4. The sliding member 1 is sleeved on a guide rod 5, and the guide rod 5 is arranged in a material pipeline 6. In actual application, the two ends of the guide rod 5 are supported in the material pipeline 6.

[0022] As shown in Figure 1 The plurality of heat insulating diaphragms 4 are sequentially sleeved on the sliding member 1, and the end of each heat insulating diaphragm 4 away from the sliding member 1 is attached to the inner wall of the material pipeline 6. The two baffles 3 are sleeved on the guide rod 5, and the plurality of heat insulating diaphragms 4 are located between the two baffles 3. In actual application, the heat insulating diaphragm 4 is in contact with the high-temperature acidic medium in the material pipeline 6 during use, so the heat insulating diaphragm 4 is made of acid-resistant, high-temperature-resistant and poor-conductive rubber material.

[0023] Continuing to refer to Figure 1As shown, the connecting piece 2 is used to connect the sliding piece 1 and the two baffles 3. Specifically, because the heat insulation film pieces 4 will expand in the high-temperature medium, the plurality of heat insulation film pieces 4 are blocked by the two baffles 3. During the operation of the diaphragm pump, the heat insulator reciprocates in the material pipeline 6 along the guide rod 5 with the change of the volume of the diaphragm pump cavity, so as to realize the conveying of the material. The heat insulator of the present application can effectively isolate the high-temperature slurry in the material pipeline 6 from the low-temperature slurry in the diaphragm pump connecting pipeline, so as to avoid the high-temperature slurry from entering the diaphragm pump to damage the diaphragm, thereby prolonging the maintenance cycle of the diaphragm pump, and further reducing the maintenance workload and maintenance cost.

[0024] The utility model embodiment provides a kind of heat insulator, which comprises sliding piece 1, connecting piece 2, two baffles 3 and multiple heat insulation film pieces 4. Sliding piece 1 is set in guide rod 5, and guide rod 5 is arranged in material pipeline 6. Multiple heat insulation film pieces 4 are sequentially set in sliding piece 1, and the end of each heat insulation film piece 4 away from sliding piece 1 is attached to the inner wall of material pipeline 6. Two baffles 3 are all set in guide rod 5, and multiple heat insulation film pieces 4 are located between two baffles 3. Connecting piece 2 is used to connect sliding piece 1 and two baffles 3. The heat insulator of the present application can effectively isolate the high-temperature slurry in the material pipeline 6 from the low-temperature slurry in the diaphragm pump connecting pipeline, so as to avoid the high-temperature slurry from entering the diaphragm pump to damage the diaphragm, thereby prolonging the maintenance cycle of the diaphragm pump, and further reducing the maintenance workload and maintenance cost.

[0025] As shown in Figure 1 Connecting piece 2 includes connecting rod 21 and locking nut 22. The middle part of connecting rod 21 is connected with sliding piece 1, and the two ends of connecting rod 21 are connected with baffles 3 at corresponding positions respectively after extending out of sliding piece 1 and are tightened with a locking nut 22. In actual application, connecting rod 21 is first connected with two baffles 3 and sliding piece 1, and then a locking nut 22 is tightened at each end of connecting rod 21 to fix sliding piece 1 between two baffles 3.

[0026] In the embodiment of the present application, connecting rod 21 includes a tension stud. Specifically, the tension stud can generate a large fastening tension, has strong adjustability, and is relatively simple to install and maintain.

[0027] As shown in Figure 4 Sliding piece 1 includes sliding bearing seat 11, two sliding bearings 12 and two sliding bearing covers 13. Two sliding bearings 12 are installed in sliding bearing seat 11, and two sliding bearings 12 are set in guide rod 5. Two sliding bearing covers 13 are connected to the two ends of sliding bearing seat 11 respectively to fix sliding bearings 12 at corresponding positions. Specifically, through the cooperation of sliding bearing seat 11, two sliding bearings 12 and two sliding bearing covers 13, the sliding of the heat insulator on guide rod 5 is realized, so as to realize the reciprocating movement of the heat insulator in material pipeline 6, and the structure is simple.

[0028] As shown in Figure 3 The heat insulation diaphragm 4 includes a diaphragm body 41 and a circular arc boss 42. The diaphragm body 41 is sleeved on the sliding member 1. The circular arc boss 42 is arranged at one end of the heat insulation diaphragm 4 away from the sliding member 1. In practical application, the circular arc boss 42 can not only increase the bending strength of the heat insulation diaphragm 4, but also reduce the friction area between the heat insulation diaphragm 4 and the material pipeline 6, thereby reducing the friction force in the movement process of the heat insulation diaphragm 4, increasing the service life of the heat insulation diaphragm 4 without reducing the heat insulation effect of the heat insulation diaphragm 4, and further reducing the maintenance frequency of the heat insulation device.

[0029] In practical application, the circular arc boss 42 and the diaphragm body 41 are integrally formed. Specifically, integrally forming the circular arc boss 42 and the diaphragm body 41 can make the strength of the heat insulation diaphragm 4 higher, and further increase the service life of the heat insulation diaphragm 4.

[0030] Each of the embodiments in the specification is described in a progressive manner, and the same or similar parts between the embodiments can be referred to each other. Each of the embodiments mainly describes the difference from other embodiments.

Although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that the technical solutions recorded in the foregoing examples can still be modified, or some or all of the technical features can be replaced by equivalents.
