Description

Technical Field

[0001] The present application relates to the field of single screw pumps, and in particular to a single screw pump that is easy to move. Background Art

[0002] The single screw pump is a positive displacement pump that uses one or more screws to rotate in the pump body and transport fluids through the close fit between the screw and the pump body. The unique design of this pump is that it can smoothly and continuously transport various types of media, including high-viscosity liquids, slurries containing solid particles, and shear-sensitive fluids. Due to these characteristics, single screw pumps are widely used in many industries such as chemical, pharmaceutical, food processing, shipping, and sewage treatment.

[0003] However, despite its many advantages, such as high efficiency, reliability and gentle handling of the media, the single-screw pump also has some disadvantages. One of them is its inconvenience in mobility. Since single-screw pumps are usually bulky, especially when they are designed for industrial-scale applications, it becomes difficult to install and move them on site. In addition, if the pump equipment needs to be frequently moved between different job sites, the weight and size of the single-screw pump will become a challenge, so there is room for improvement. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present application provides a single-screw pump that is easy to move, aiming to solve the above problems.

[0005] A single-screw pump that is easy to move includes a base and a body installed on the base, wherein mounting grooves are provided at the four corners of the lower end surface of the base, a connecting rod is installed in the mounting groove, the connecting rod is rotatably connected to the two inner side walls facing each other of the mounting groove, the movable end of the connecting rod is rotatably connected to a universal wheel, a first mounting hole is provided on the bottom wall of the mounting groove, the first mounting hole extends to the upper end surface of the base, a mounting bolt is threadedly connected to the first mounting hole, a connecting groove is provided at one end of the connecting rod away from the universal wheel, a limiting column is installed in the connecting groove, and a limiting groove for one end of the mounting bolt to be inserted into is provided on the limiting block.

[0006] By adopting the above technical solution, when the single-screw pump needs to be moved, the connecting rod is rotated out of the installation groove, and then the installation bolt is screwed into the first installation hole, so that one end of the installation bolt is stuck in the limit groove of the limit column, thereby limiting the rotation of the connecting rod, so that the connecting rod remains in a vertical state, the universal wheel is in contact with the road surface, and the base can move on the ground through the universal wheel, saving time and effort; after the single-screw pump is moved to the installation position, the installation bolt is screwed out of the first installation hole, and the connecting rod is rotated into the installation groove, so as to facilitate the installation of the body.

[0008] By adopting the above technical solution, the mounting bolt is screwed into the first mounting hole so that one end of the mounting bolt is stuck in the limiting groove, thereby pushing the limiting column into the connecting groove, the limiting column presses the shock-absorbing spring, and the shock-absorbing spring presses the fixing ring. When the universal wheel moves on the ground, the shock-absorbing spring can reduce shock, thereby reducing the vibration of the base; in addition, according to the conditions of the road surface, the shock-absorbing spring is rotated to adjust the position of the limiting column in the connecting groove, thereby adjusting the force of the shock-absorbing spring pressing against the fixing ring, so that the universal wheel can adapt to different road surfaces.

[0009] Optionally, an elastic shock-absorbing pad is connected to an end of the positioning rod away from the universal wheel.

[0010] By adopting the above technical solution, the shock-absorbing pad can buffer the impact force between the positioning rod and the limiting column.

[0011] Optionally, a second mounting hole for a mounting bolt to be screwed into is provided on the vertical side wall of the base, and a slot for one end of the mounting bolt to be inserted into is provided on the outer side wall of the connecting rod.

[0012] By adopting the above technical solution, when the single-screw pump needs to be moved, the mounting bolt is unscrewed from the first mounting hole, the connecting rod is then turned into the mounting groove, and then the mounting bolt is screwed into the second mounting hole, so that one end of the mounting bolt is inserted into the groove on the connecting rod, thereby preventing the connecting rod from accidentally falling out of the mounting groove.

[0013] Optionally, a soundproof cover for covering the body is installed on the base, and sound insulation cotton is connected to the inner wall of the soundproof cover. The circumferential inner wall of the soundproof cover is tightly attached to the vertical outer wall of the base, and four limiting holes for mounting bolts to be inserted are opened on the edge of the soundproof cover.

[0014] By adopting the above technical solution, the sound insulation cover covers the machine body, and the sound insulation cotton in the sound insulation cover can absorb the noise generated by the machine body, thereby reducing the noise transmission; when installing the sound insulation cover, it is only necessary to align the limiting holes on the sound insulation cover with the mounting bolts, and fix them into the limiting holes, and then tighten the mounting bolts.

[0015] Optionally, a first magnet is embedded on the outer wall of the connecting rod, and a second magnet that attracts the first magnet is embedded on the bottom wall of the mounting groove.

[0016] By adopting the above technical solution, when the connecting rod is rotated into the installation groove, the first magnet and the second magnet on the connecting rod attract each other, thereby preventing the connecting rod from accidentally rotating out of the installation groove, thereby facilitating the subsequent installation of the mounting bolts.

[0017] Optionally, a mounting strip is connected to the inner wall of the soundproof cover, and both ends of the mounting strip are vertically connected with positioning columns for inserting into the first mounting holes.

[0018] By adopting the above technical solution, when installing the sound insulation cover, the relative position of the sound insulation cover and the base can be quickly determined by inserting the positioning column into the first installation hole, thereby facilitating the rapid installation of the sound insulation cover.

[0019] Optionally, one end of the positioning column is connected to a guide block.

[0020] By adopting the above technical solution, the guide block can provide a guiding effect to the positioning column, so that the positioning column can be quickly and smoothly inserted into the first mounting hole.

[0021] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the single-screw pump needs to be moved, the connecting rod is rotated out of the mounting groove, and then the mounting bolt is screwed into the first mounting hole so that one end of the mounting bolt is stuck in the limiting groove of the limiting column, thereby limiting the rotation of the connecting rod, so that the connecting rod remains in a vertical state, the universal wheel is in contact with the road surface, and the base can move on the ground through the universal wheel, saving time and effort; after the single-screw pump is moved to the installation position, the mounting bolt is screwed out of the first mounting hole, and the connecting rod is rotated into the mounting groove, so as to facilitate the installation of the body.

[0022] 2. Screw the mounting bolt into the first mounting hole so that one end of the mounting bolt is stuck in the limit groove, thereby pushing the limit column into the connecting groove. The limit column presses the shock-absorbing spring, and the shock-absorbing spring presses the fixing ring. When the universal wheel moves on the ground, the shock-absorbing spring can reduce shock, thereby reducing the vibration of the base; in addition, according to the conditions of the road surface, rotate the shock-absorbing spring and adjust the position of the limit column in the connecting groove, thereby adjusting the strength of the shock-absorbing spring pressing against the fixing ring, so that the universal wheel can adapt to different road surfaces.

[0023] 3. When the single screw pump needs to be moved, unscrew the mounting bolt from the first mounting hole, then turn the connecting rod into the mounting groove, and then screw the mounting bolt into the second mounting hole so that one end of the mounting bolt is inserted into the groove on the connecting rod, thereby preventing the connecting rod from accidentally falling out of the mounting groove.

[0024] 4.
