Description

Technical Field

[0001] The utility model belongs to the technical field of vacuum filters and relates to a wear-resistant integrated vacuum chamber. Background Art

[0002] At present, the rubber belt vacuum filter industry generally uses the form of "slide + diamond vacuum chamber" for drainage. This structure is used in the quartz sand industry because the diamond vacuum chamber is made of 304 or carbon steel, which is not wear-resistant, has a short service life, a high replacement frequency, and a high cost. In addition, the drainage position of the diamond vacuum chamber is not easy to adjust after installation.

[0003] In view of the above problems, a wear-resistant integrated vacuum chamber is proposed. Utility Model Content

[0004] In order to solve the problems existing in the background technology, the utility model proposes a wear-resistant integrated vacuum chamber.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A wear-resistant integrated vacuum chamber includes a slide and a drainage elbow. The lower end of the slide is connected to a fixed pipe, the outer wall of the fixed pipe is provided with an external thread, and the inner wall of the drainage elbow near one end of the fixed pipe is provided with an internal thread, and the internal thread is adapted to the external thread.

[0007] Furthermore, a plurality of slide grooves are provided on the fixed pipe, and a rotating ring is rotatably connected to one end of the drainage elbow close to the fixed pipe, and a plurality of sliding rods are fixed on the rotating ring, and the plurality of sliding rods are adapted to the plurality of slide grooves.

[0008] Furthermore, a pushing frame is fixedly connected to the drainage elbow, and the pushing frame is arranged in an L-shape. A limiting plate is slidably connected to the pushing frame. A fixing pin is provided at the end of the limiting plate opposite to the rotating ring. A plurality of limiting holes are opened on the rotating ring, and the fixing pins and the limiting holes correspond to each other.

[0009] Furthermore, a fixing spring is provided between the limiting plate and the pushing frame, and two ends of the fixing spring are fixedly connected to the limiting plate and the pushing frame respectively.

[0010] Furthermore, the pushing frame is located outside the rotating ring.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. This solution uses polymer wear-resistant materials, and the drainage elbow and the fixed pipe are connected by threads, which is convenient for replacement. The utility model takes into account the characteristics of liquid storage, wear resistance, and simple structure, and eliminates the diamond vacuum cavity in the original structure, ensuring that the filtered liquid can be effectively discharged.

[0013] 2. This solution provides a rotating ring so that after the fixed pipe and the drainage elbow are connected by threads, under the action of the fixing pin, the drainage elbow will not separate from the fixed pipe even in a vibrating working environment, thereby increasing stability.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1

[0023] like Figure 1-Figure 6 The technical solution adopted by the utility model is as follows: a wear-resistant integrated vacuum chamber, including a slide 1 and a drainage elbow 3, wherein Figure 6The structure of the diamond-shaped vacuum chamber 14 in the prior art is shown in the figure. The lower end of the slide 1 is connected to a fixed pipe 2, the outer wall of the fixed pipe 2 is provided with an external thread 5, and the inner wall of the drainage elbow 3 near one end of the fixed pipe 2 is provided with an internal thread 6, and the internal thread 6 and the external thread 5 are adapted to each other.

[0024] The drain elbow 3 and the fixed pipe 2 are connected via an external thread 5 and an internal thread 6. When the drain elbow 3 needs to be replaced, it can be replaced by twisting it, which is easy to operate.

[0025] Embodiment 2

[0026] A plurality of chutes 8 are provided on the fixed pipe 2. A rotating ring 4 is rotatably connected to one end of the drainage elbow 3 close to the fixed pipe 2. A plurality of slide bars 7 are fixedly provided on the rotating ring 4, and the plurality of slide bars 7 are adapted to the plurality of chutes 8.

[0027] A push frame 9 is fixedly connected to the drain elbow 3 , and the push frame 9 is arranged in an L-shaped manner. The push frame 9 is located outside the rotating ring 4 .

[0028] The push frame 9 is connected to the limit plate 10 by sliding. The limit plate 10 can only slide along the push frame 9 and cannot be separated from the push frame 9. Figure 5 , the sliding direction of the limit plate 10 is opposite to the center direction of the rotating ring 4. A fixing pin 11 is fixedly provided at the end of the limit plate 10 opposite to the rotating ring 4. A plurality of limit holes 13 are provided on the rotating ring 4, and the opening direction of the limit holes 13 is opposite to the center direction of the rotating ring 4. The fixing pin 11 and the limit holes 13 correspond to each other. A fixing spring 12 is provided between the limit plate 10 and the pushing frame 9, and the two ends of the fixing spring 12 are fixedly connected to the limit plate 10 and the pushing frame 9 respectively.

[0029] When the drainage elbow 3 is connected to the fixed pipe 2, the positions of the plurality of slide bars 7 and the plurality of slide grooves 8 correspond to each other, and then the slide bars 7 are inserted into the slide grooves 8 for positioning. The fixed pipe 2 and the drainage elbow 3 can be directly aligned to ensure the tightness of the wear-resistant integrated vacuum chamber.

[0030] When the internal thread 6 and the external thread 5 are in contact, the drain elbow 3 is rotated so that the internal thread 6 and the external thread 5 are meshed with each other. At this time, the rotating ring 4 will rotate with the fixed pipe 2. After the fixed pipe 2 and the drain elbow 3 are connected, the fixing pin 11 is inserted into the limiting hole 13 at the corresponding position to prevent the internal thread 6 and the external thread 5 from vibrating and separating when the slide table vibrates, thereby improving the practicality of the wear-resistant integrated vacuum chamber.
