Description

Technical Field

[0001] The utility model relates to the technical field of gas filter installation, in particular to a medium and low pressure filter with installation auxiliary support equipment. Background Technique

[0002] Gas filters are widely used in gas-using fields such as metallurgy, chemical industry, petroleum, paper-making, medicine, food, mining, electric power, cities, and families. A gas filter is an indispensable device on a pipeline for conveying a medium. It is usually installed at the inlet end of a pressure reducing valve, a pressure relief valve, a positioning valve or other equipment to remove impurities in the medium to protect the normal use of valves and equipment and reduce equipment maintenance costs.

[0003] Gas filters are divided into high-pressure gas filters and medium and low-pressure gas filters. The medium and low-pressure gas filters bear lower air pressures, and their two ends are connected to pipelines through flanges. During installation, due to the lack of necessary support at the pipeline ends and the relatively heavy weight of the gas filter, the pipeline ends are bent and sag, making it difficult to install the gas filter. Therefore, it is necessary to support and position the installed gas filter and at the same time support and lift the pipeline ends to be connected to facilitate the installation and fixation of the two. Content of the Utility Model

[0004] The utility model aims at the defects in the prior art and provides a medium and low pressure filter with installation auxiliary support equipment.

[0005] The utility model is realized by the following technical solutions:

[0006] A medium and low pressure filter with installation auxiliary support equipment includes a bottom plate, a connecting plate, a support mechanism, a side support mechanism and a medium and low pressure filter body. The connecting plate is fixedly arranged on the upper surface of the bottom plate. The support mechanism is arranged in the middle of the connecting plate. The side support mechanism is arranged outside the connecting plate. The medium and low pressure filter body is clamped on the top of the support mechanism. The support mechanism includes a lifting plate, a support plate, a sleeve, a screw rod and a rotating handle. The sleeve is fixedly arranged on the upper surface of the bottom plate. The screw rod is movably connected with the sleeve. The rotating handle is fixedly connected to the outer side of the bottom of the screw rod. The lifting plate is movably connected with the screw rod. The support plate is fixedly arranged at both ends of the top of the lifting plate.

[0007] In a preferred embodiment of the utility model, the side support mechanism includes a mounting frame, a folding plate, a limiting rod, a knob and a contact ring. The mounting frame is fixedly arranged outside the connecting plate. The folding plate is movably connected with the mounting frame. The limiting rod is fixedly arranged outside the connecting plate. The knob is movably connected with the limiting rod. The contact ring is movably connected to one end of the knob;

[0008] The side support mechanism mainly supports the pipes connected to both ends of the medium and low pressure filter body by changing the angle of the folding plate, and raises the pipe ends to match the height of the connection end of the medium and low pressure filter body, so as to facilitate the installation work.

[0009] In a preferred embodiment of the present invention, one end of the limit rod penetrates and extends to the outside of one side of the folding plate, and a waist-shaped hole matching the limit rod is formed on the surface of the folding plate;

[0010] When adjusting the angle of the folding plate, the waist-shaped hole on the surface of the folding plate avoids interference with the limit rod.

[0011] In a preferred embodiment of the present invention, a threaded groove is formed on the surface of the limit rod, the knob is threadedly connected to the limit rod, and one end of the contact ring contacts the outside of the folding plate;

[0012] By adjusting the knob on the limit rod, the contact ring limits the folding angle of the folding plate, so that the end of the folding plate effectively supports and adjusts the end of the pipe.

[0013] In a preferred embodiment of the present invention, a limit plate is provided at the top of the screw rod, both ends of the lifting plate are clamped inside the connecting plate, and guiding sliding grooves matching both ends of the lifting plate are formed inside the connecting plate.

[0014] In a preferred embodiment of the present invention, arc-shaped grooves are formed at the top of the support plate and the top of the folding plate, and the top of the support plate is clamped at the bottom of the medium and low pressure filter body.

[0015] The beneficial effects of the present invention are:

[0016] The medium and low pressure filter with the installation auxiliary support device supports the gas medium and low pressure filter, making it in a horizontal state, facilitating the connection with the flange at the end of the pipe. And the side support mechanism supports the end of the pipe by changing the angle of the folding plate, and controls the end to lift, so as to ensure that the flange at the end of the pipe matches the height of the connection flange of the filter, thus facilitating the bolt installation work of the connection flange.

[0021] The following will elaborate on the preferred embodiments of the present invention in conjunction with the attached drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention. The directional terms mentioned in the present invention, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom", etc., are only with reference to the directions of the attached drawings. Therefore, the directional terms used are for explaining and understanding the present invention, rather than for limiting the present invention.

[0022] As Figures 1-3 Shown is a medium and low pressure filter with an installation auxiliary support device, including a bottom plate 1, a connecting plate 2, a support mechanism 3, a side support mechanism 4 and a medium and low pressure filter body 5. The connecting plate 2 is fixedly arranged on the upper surface of the bottom plate 1. The support mechanism 3 is arranged in the middle of the connecting plate 2. The side support mechanism 4 is arranged outside the connecting plate 2. The medium and low pressure filter body 5 is clamped on the top of the support mechanism 3. The support mechanism 3 includes a lifting plate 31, a support plate 32, a sleeve 33, a screw 34 and a rotating handle 35. The sleeve 33 is fixedly arranged on the upper surface of the bottom plate 1. The screw 34 is movably connected with the sleeve 33. The rotating handle 35 is fixedly connected to the outer side of the bottom of the screw 34. The lifting plate 31 is movably connected with the screw 34. The support plate 32 is fixedly arranged at both ends of the top of the lifting plate 31.

[0023] Specifically, the side support mechanism 4 includes a mounting bracket 41, a folding plate 42, a limiting rod 43, a knob 44 and a contact ring 45. The mounting bracket 41 is fixedly arranged outside the connecting plate 2. The folding plate 42 is movably connected with the mounting bracket 41. The limiting rod 43 is fixedly arranged outside the connecting plate 2. The knob 44 is movably connected with the limiting rod 43. The contact ring 45 is movably connected to one end of the knob 44. One end of the limiting rod 43 penetrates and extends to the outside of one side of the folding plate 42. A waist-shaped hole matching the limiting rod 43 is formed on the surface of the folding plate 42. A threaded groove is formed on the surface of the limiting rod 43. The knob 44 is threadedly connected with the limiting rod 43. One end of the contact ring 45 contacts the outside of the folding plate 42. A limiting plate is arranged at the top of the screw 34. Both ends of the lifting plate 31 are clamped inside the connecting plate 2. Guide chutes matching both ends of the lifting plate 31 are formed inside the connecting plate 2. Arc-shaped grooves are formed at the tops of the support plate 32 and the folding plate 42. The top of the support plate 32 is clamped at the bottom of the medium and low pressure filter body 5.

[0024] In this embodiment, first, the medium and low pressure filter body 5 to be installed is clamped to the top of the support plate 32. The arc-shaped grooves at the top of the support plate 32 are clamped to the bottoms of the flanges at both ends of the medium and low pressure filter body 5. Then, the bottom plate 1 is moved until the side support mechanism 4 is located at the bottom of one end of the pipeline. Subsequently, the folding plate 42 is turned upward so that the folding plate 42 rotates upward along the clamping shaft inside the mounting frame 41 until its top contacts the bottom of the pipeline. Then, the knob 44 is screwed on, and the knob 44 is rotated on the surface of the limiting rod 43 so that the contact ring 45 movably connected to one end of the knob 44 presses against the outside of the folding plate 42, and the folding plate 42 is continuously controlled to rotate upward until the end of the pipeline is in a horizontal state.

[0025] Further, by adjusting the rotating handle 35 and controlling the rotation of the screw 34, the lifting plate 31 connected by threads can be adjusted in height. Both ends of the lifting plate 31 are clamped inside the connecting plate 2, playing a role of guiding and limiting, to prevent the lifting plate 31 from rotating along with the screw 34 during the adjustment process. By adjusting the height of the lifting plate 31, the height of the medium and low pressure filter body 5 clamped to the top of the support plate 32 is adjusted until the positions of the connecting flanges at both ends correspond to the positions of the connecting flanges at the ends of the pipeline, and the positions of the two groups of flanges are relatively fixed, thus facilitating the installation work.
