DETAILED DESCRIPTION

[0022] 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.

[0023] When implementing: Figure 1-4As shown, a plate heat exchanger with filtering comprises: a base 1, a fixed plate 3 is fixedly connected to the upper end of the base 1, a movable plate 2 and a plurality of plates 4 are slidably connected to the upper end of the base 1, the plurality of plates 4 are arranged on the side close to the movable plate 2 and the fixed plate 3, a plurality of pipes 5 are fixedly connected to the inner wall of the fixed plate 3, the movable plate 2 and the plates 4 are slidably connected to the surfaces of the plurality of pipes 5; a clamping mechanism 6 is arranged on one side of the fixed plate 3 for pushing the movable plate 2 close to the fixed plate 3 so that the plurality of plates 4 are clamped and fitted; a positioning pushing component 7 is arranged on the upper side of the base 1 for more stable positioning when the movable plate 2 slides; wherein the clamping mechanism 6 comprises a synchronous pushing component 601 arranged on one side of the fixed plate 3, and a synchronous pushing component 601 is arranged on one side of the fixed plate 3 A limiting component 602 is set, and the synchronous pushing component 601 is rotated. The synchronous pushing component 601 pushes the movable plate 2 to approach the fixed plate 3 from multiple positions, and pushes multiple plates 4 to approach each other and fit one side of the fixed plate 3 for clamping. The synchronous pushing component 601 pushes multiple pushing points synchronously to prevent the movable plate 2 from tilting when being pushed, and is more stable. The limiting component 602 makes the movable plate 2 more stable when pushing the plate 4 to clamp. The pushing distance of the movable plate 2 can be checked by positioning the pushing component 7, and the pushing distance can be accurately controlled to prevent extrusion damage caused by excessive pushing. The pipe 5 includes a filter net, an activated carbon adsorption box and other filtering components inside. The filtering and adsorption components on the inner wall of the pipe 5 have the same structure as in the comparative document, so they will not be described in detail.

[0024] like Figure 2 and Figure 3As shown, the synchronous pushing assembly 601 includes two lead screws 6012 rotatably connected to the inner wall of the fixed plate 3, and the side end of the movable plate 2 close to the base 1 is fixedly connected to two threaded sleeves 6011, and the two lead screws 6012 are respectively threadedly connected to the inner walls of the two threaded sleeves 6011. When it is necessary to pull the movable plate 2 closer to the fixed plate 3 so that the plates 4 are pressed and fitted against each other, the two lead screws 6012 are rotated at this time, and the lead screws 6012 drive the threaded sleeves 6011 and the movable plate 2 to the fixed plate 3 through the threads. The fixed plate 3 is close to each other, and the multiple plates 4 between the fixed plate 3 and the movable plate 2 are squeezed and clamped. When the lead screw 6012 and the threaded sleeve 6011 are threadedly pulled, the threaded rod will not extend out to occupy space, and objects will not be hooked during transportation and maintenance. The circumferential surfaces of the two lead screws 6012 are fixedly connected with toothed pulleys 6013, and the surfaces of the toothed pulleys 6013 are provided with synchronous belts 6014. The two toothed pulleys 6013 are meshed and driven by the synchronous belts 6014. When one of the lead screws 6012 is engaged, When rotating, it will drive the toothed belt wheel 6013 to rotate, and the toothed belt wheel 6013 drives another toothed belt wheel 6013 to rotate through the synchronous belt 6014. At this time, the two toothed belt wheels 6013 and the lead screw 6012 rotate synchronously, and can be pulled synchronously to prevent the synchronous pushing component 601 from pulling the movable plate 2 due to the different feeding speeds on both sides, which causes the movable plate 2 to be skewed and worn. The circumferential surface of the lead screw 6012 is fixedly connected to the worm gear 6015, and the side end of the fixed plate 3 is fixedly connected to the rotating frame 601 7. The inner wall of the rotating frame 6017 is rotatably connected with a worm 6016, and the worm wheel 6015 is meshed with the worm 6016. When it is necessary to drive the lead screw 6012 to rotate, the worm 6016 can be rotated, and the worm 6016 drives the worm wheel 6015 and one of the lead screws 6012 to rotate. Through the meshing of the worm 6016 and the worm wheel 6015, the rotation of the lead screw 6012 can be self-locked to prevent the lead screw 6012 from rotating by itself after the adjustment is completed, resulting in the loosening of the fixation of the plate 4.

[0025] like Figure 2 and Figure 4As shown, the limiting assembly 602 is provided with multiple groups, and each group of limiting assemblies 602 includes a slide bar 6024 fixedly connected to the side end of the fixed plate 3, and a sliding sleeve 6022 is provided on the surface of the slide bar 6024. The inner wall of the sliding sleeve 6022 is fixedly connected with a connecting plate 6021, and the connecting plate 6021 is detachably connected to the movable plate 2 through bolts. When the synchronous pushing assembly 601 pulls the movable plate 2 to fit the plate 4 for extrusion, the movable plate 2 is prone to tilt at an angle, and the sliding sleeve 60 22 slides on the surface of the slide bar 6024, and the movable plate 2 is more stable when sliding. A fitting block 6023 is fixedly connected to one end of the slide bar 6024. The fitting block 6023 is slidably connected to the inner wall of the sliding sleeve 6022. The fitting block 6023 fits closely with the inner wall of the sliding sleeve 6022. When the sliding sleeve 6022 slides on the surface of the slide bar 6024, the fitting block 6023 is driven to slide on the inner wall of the sliding sleeve 6022 to provide support and prevent the slide bar 6024 from being deformed or damaged.

[0026] like Figure 3 As shown, the positioning and pushing component 7 includes a positioning rail 703 fixedly connected to the upper end of the base 1, and the movable plate 2 is slidably connected to the surface of the positioning rail 703. The positioning rail 703 can be used to limit the sliding of the movable plate 2 to prevent the movable plate 2 from tilting left and right when sliding. A scale groove 701 is provided at the upper end of the base 1, and an indicator block 702 is fixedly connected to the side end of the movable plate 2. The lower end of the indicator block 702 fits the lower inner wall of the scale groove 701. When the movable plate 2 is pulled by the synchronous pushing component 601, excessive pulling and squeezing will cause damage to the plate 4 and the synchronous pushing component 601. The pulling distance can be accurately controlled by the indicating length of the indicator block 702 and the scale groove 701. The reasonable pulling distance can be controlled by the number of plates 4 and the thickness of the plates 4 to prevent the synchronous pushing component 601 from being damaged due to excessive pulling.

[0027] When the utility model is in use, when the plate 4 is clamped by installing the device, the worm 6016 is rotated at this time, and the worm 6016 drives the worm wheel 6015 and one of the lead screws 6012 to rotate, and the lead screw 6012 drives one of the toothed belt pulleys 6013 to rotate, and the toothed belt pulley 6013 drives the other toothed belt pulley 6013 to rotate through the synchronous belt 6014. At this time, the two toothed belt pulleys 6013 and the lead screw 6012 rotate synchronously, and the two lead screws 6012 simultaneously pull the two threaded sleeves 6011 close together, and the threaded sleeve 6011 pulls the movable plate 2 close to the fixed plate 3, and the multiple plates 4 located between the fixed plate 3 and the movable plate 2 are squeezed and clamped. When the lead screw 6012 and the threaded sleeve 6011 are pulled by threads, the threaded rod will not extend out to occupy space, and objects will not be hooked during transportation and maintenance. At the same time, the two lead screws 6012 rotate synchronously, which can make the pulling distance the same, thereby preventing the movable plate 2 from tilting due to the different pulling distances on both sides.

[0028] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
