DETAILED DESCRIPTION

[0025] A method for preparing a sewage treatment flocculant, the method comprising the following steps:

[0026] Step 1: Connect the produced sewage treatment flocculant particles to the preparation device;

[0027] Step 2: Overlapping the water-soluble film into the preparation device and packaging the sewage treatment flocculant particles;

[0028] Step 3: using a preparation device to heat-melt a piece of water-soluble film in different regions and receive the sewage treatment flocculant particles for regional packaging, and using the preparation device to uniformly package the sewage treatment flocculant particles;

[0029] Step 4: Collect the water-soluble film that is packaged with the sewage treatment flocculant particles and hot-melted.

[0030] This part is based on Figure 1-11 The working process expressed therein is: when preparing and producing sewage treatment flocculant particles, in order to facilitate the production of flocculants by using water-soluble films to encapsulate the produced flocculants so as to improve the convenience of using the flocculants and the convenience of carrying them around, when using, first cut off a piece of water-soluble film for encapsulating sewage treatment flocculant particles. The water-soluble film is a prior art product and will not be introduced. Then, the two ends of the water-soluble film are hung up, and the middle of the water-soluble film is made to hang downward, and the sewage treatment flocculant particles are poured into the water-soluble film, and the two opening and closing barrels 102 on the limit column 101 are rotated to open and close, so that the position at the bottom of the two opening and closing barrels 102 that are rotated and connected to the limit column 101 is the center. The two clamping plates 103 located on the inner side of the two opening and closing barrels 102 are moved closer to the middle when merging. At this time, the annular rings 104 located on the two clamping plates 103 are in their annular state and electrically heated to heat-melt the water-soluble film. Before the sewage treatment flocculant particles are poured into the water-soluble film hanging downward in the middle, the two annular rings 104 follow the opening and closing of the opening and closing barrel 102. First, the bottom of the two annular rings 104 is used to heat-melt the water-soluble film. At this time, the flocculant is poured in again, and the opening and closing of the opening and closing barrel 102 is followed so that the two annular rings 104 gradually heat-melt the entire water-soluble film filled with flocculant.

[0031] In order to facilitate the regional bonding of the same water-soluble film and to allow the flocculants to be respectively contained between the interval positions of the water-soluble film, when in use, a plurality of rectangular strips 109 are processed on each clamping plate 103 by a milling machine, and each rectangular strip 109 is slidably connected to a sliding frame 203 on one side close to the inside of the opening and closing barrel 102, so that each sliding frame 203 is fixedly connected to an electric heating rod 204, and each vertically arranged electric heating rod 204 is pushed by each sliding frame 203, so that each electric heating rod 204 that is electrically heated can bond the water-soluble film in different regions, and then the flocculant is injected, so that when a small amount of flocculant is used later, the flocculant in the area can be directly torn off along the hot-melt bonding position of the divided area, which is simple and quick, and is convenient for using the flocculant in an appropriate amount to avoid wasting the flocculant.

[0032] This part is based on Figure 1-11 The working process expressed therein is: when the two clamping plates 103 are close to the water-soluble film, a movable frame 105 is fixedly connected to the outer side of the two clamping plates 103 by bolts respectively, the tops of the two movable frames 105 are fixedly connected to the movable ends of the two electric push rods Ⅰ106 by flanges respectively, the fixed ends of the two electric push rods Ⅰ106 are fixedly connected to the tops of the two opening and closing barrels 102 by flanges respectively, and the two electric push rods Ⅰ106 are driven respectively, so that the movable frames 105 on the movable ends of the two electric push rods Ⅰ106 drive the two clamping plates 103 to gradually approach the water-soluble film for hot-melt bonding.

[0033] The limiting column 101 is fixedly connected to the middle part of the feeding rack 401, and the bottom of the feeding rack 401 is fixedly connected to the base 402, and the fixed end of the two-way push rod Ⅰ108 is fixedly connected to the base 402. The two movable ends of the two-way push rod Ⅰ108 are respectively rotatably connected to a pushing frame 107, and the upper ends of the two pushing frames 107 are respectively rotatably connected to the bottoms of the two opening and closing barrels 102.

[0034] A reserve barrel 403 is fixedly connected to the top of the feed rack 401 .

[0035] This part is based on Figure 1-11The working process expressed in the figure is: when the two opening and closing barrels 102 are opened and closed with the limiting column 101 as the center, the limiting column 101 is fixedly connected to the middle of the feeding frame 401 by bolts, and is rotatably connected to the two pushing frames 107 at the bottom of the two opening and closing barrels 102. The bottoms of the two pushing frames 107 are rotatably connected to the two active ends of the two-way push rod Ⅰ108. When the two opening and closing barrels 102 are opened and closed, the two-way push rod Ⅰ108 is driven so that the two active ends of the two-way push rod Ⅰ108 are moved. The pushing frame 107 on the moving end pushes the opening and closing barrel 102 upward, so that the clamping plate 103 located inside the two opening and closing barrels 102 can be clamped and adhered to the surface of the water-soluble film for hot melting. This working method is convenient for hot melting to be performed gradually from the bottom to the top, preventing the flocculant from being poured in when the hot-melt water-soluble film is simultaneously adhered. When pouring the flocculant, pour the flocculant into the reserve barrel 403 before work, and the reserve barrel 403 is fixedly connected to the top of the feed rack 401 by bolts.

[0036] The multiple sliding frames 203 located on the front side are fixedly connected to a connecting plate 201 in sequence, and the multiple sliding frames 203 located on the rear side are fixedly connected to another connecting plate 201 in sequence. The rear sides of the two connecting plates 201 are respectively fixedly connected to the movable end of an electric push rod Ⅱ 202, and the fixed ends of the two electric push rods Ⅱ 202 are respectively fixedly connected to one end of the outer side of the two clamping plates 103.

[0037] This part is based on Figure 1-11 The working process expressed in the figure is: when the water-soluble film is hot-melted and bonded in different areas so as to facilitate the zoning of flocculants, the multiple sliding racks 203 arranged on the front and rear sides are respectively fixedly connected to the two connecting plates 201 by welding. When the two connecting plates 201 push the multiple sliding racks 203 thereon to move, the movable end of an electric push rod Ⅱ 202 is fixedly connected to the rear side of each connecting plate 201 by a flange, and then the fixed ends of the two electric push rods Ⅱ 202 are respectively fixedly connected to the two clamping plates by flanges. 103, and then drive two electric push rods II 202 so that the two connecting plates 201 push the multiple sliding frames 203 thereon to drive the electric heating rods 204 to move through the corresponding rectangular strips 109. The positions of the electric heating rods 204 on both sides are mirror-imaged, and the distance between them is used to facilitate the water-soluble film to be hot-melted and pasted at intervals. When a small amount of flocculant is used later, the flocculant in the area can be directly torn off along the hot-melt pasting position of the divided area. This is simple and quick, and is convenient for using the flocculant in an appropriate amount to avoid wasting the flocculant.

[0038] The middle part of the limiting column 101 is slidably connected with a push rack 301, and the front and rear sides of the right top of the push rack 301 are respectively fixedly connected with a biasing plate 302, and the left side of the top of the two biasing plates 302 is respectively rotatably connected with a winding roller 304.

[0039] This part is based on Figure 1-11 The working process expressed therein is: when the water-soluble film moves to the lower side of the reserve barrel 403, the push rack 301 is manually pushed to move to the left on the limiting column 101. Prior to this, the two ends of the water-soluble film are overlapped on two winding rollers 304 rotatably connected to the tops of the two offset plates 302, and the middle part of the water-soluble film is hung downward to form a V shape, so that the flocculant can be placed between the bottom V shape, and the two sides are conveniently hot-melted and bonded, thereby packaging the flocculant powder.

[0040] A strip hole plate 303 with a strip hole in the middle is respectively provided at the bottom of the two offset plates 302, and a mirror-image vertical frame 306 is slidably connected to the two strip hole plates 303 through the strip holes. The outer sides of the two vertical frames 306 are respectively fixedly connected to the movable ends of the two-way push rod II 305, and the fixed end of the two-way push rod II 305 is fixedly connected to the middle of the right side of the pushing frame 301.

[0041] A rubber pressing strip 307 is fixedly connected to the left side of the two vertical frames 306 .

[0042] This part is based on Figure 1-11 The working process expressed in the figure is: in order to facilitate the lamination and clamping of the bottom position of the V-shaped water-soluble film, so as to prevent the bottom position from falling into the flocculant, a strip hole plate 303 with strip holes is respectively arranged horizontally at the bottom of the two offset plates 302, so that a vertical frame 306 is slidably connected in the two strip hole plates 303, and a pressing strip 307 extending to the left is fixedly connected to the left side of the two vertical frames 306, and the two pressing strips 307 are made of rubber. When the two pressing strips 307 are close to each other to clamp the bottom of the water-soluble film, they are fixedly connected to the movable ends of the two two-way push rods II 305 through flanges on the two vertical frames 306. At this time, the two-way push rods II 305 are driven so that the pressing strips 307 on the two movable ends drive the two pressing strips 307 to clamp and fit from the outer sides of the V-shaped bottom of the water-soluble film, thereby facilitating the fitting and clamping of the bottom position of the V-shaped water-soluble film, thereby preventing it from falling into the flocculant and leaving the bottom position for hot-melt bonding.
