Technical Field

[0001] The utility model relates to the technical field of magnetic rod filters for multi-effect distillation processes, and specifically relates to a magnetic rod filter for multi-effect distillation processes. Background Technique

[0002] Magnetic rod filters are used to remove iron contaminants (such as rust and iron filings) and other small ferromagnetic impurities, which can effectively improve the product purity on the production line and protect key equipment from damage by iron particles. In the process of distillation, magnetic rod filters are usually used.

[0003] For example, a magnetic rod filter with the authorization announcement number "CN209451903U", the magnetic rod is arranged in the shell, the shell isolates the magnetic rod and the liquid in the cavity, the filtering unit, the cavity is isolated into a first part and a second part by the filtering unit, the inlet is communicated with the first part, the outlet is communicated with the second part, and the shell and the magnetic rod are arranged in the first part, which has the advantages of convenient processing, etc. However, in the use of the magnetic rod filter, the magnetic rod filter is fixed to the outer shell by screwing the screws at multiple positions. The multiple-point screws require the operator to screw them one by one, increasing the disassembly and assembly difficulty of the magnetic rod filter and making it inconvenient to use the magnetic rod filter. Content of the Utility Model

[0004] The purpose of the utility model is to propose a magnetic rod filter for multi-effect distillation processes in order to solve the problem of reducing the disassembly and assembly difficulty of the magnetic rod filter and facilitating the use of the magnetic rod filter.

[0005] To achieve the above purpose, the utility model provides the following technical solution:

[0006] Design a magnetic rod filter for multi-effect distillation processes, including an outer shell and a straight pipe. The upper and lower sides of the outer shell are respectively communicated with the inner side of the straight pipe. A top cover is arranged on the front of the outer shell. Fixing structures are respectively connected to the left and right sides of the top cover. A control structure is connected to the inner wall of the top cover. Curved blocks are respectively fixedly connected to the front ends of the left and right sides of the outer shell. Bottom plates are respectively fixedly connected to the rear ends of the left and right sides of the outer shell.

[0007] Preferably, the fixing structure includes concave plates and vertical rods. The inner sides of the two concave plates are respectively fixedly connected to the left and right sides of the top cover. The upper and lower sides of the concave plates are respectively rotatably connected to the outer walls of the vertical rods. Square plates are fixedly connected to the inner sides of the vertical rods. Springs are sleeved on the outer walls of the vertical rods. The upper and lower sides of the springs are respectively fixedly connected to the inner walls of the concave plates and the outer walls of the square plates.

[0008] Preferably, a handle is fixedly connected to the outer side of the vertical rod, and a bent plate is fixedly connected to the rear end face of the square plate.

[0009] Preferably, the inner side of the bent plate is clamped with the outer wall of the curved block.

[0010] Preferably, the control structure includes a magnetic rod and a screw rod. The front of the outer wall of the magnetic rod is inserted into the inner wall of the top cover. The inner wall of the magnetic rod is threadedly connected to the outer wall of the screw rod. A cross plate is fixedly connected to the front of the screw rod.

[0011] Preferably, the rear of the outer wall of the magnetic rod is inserted into the inner wall of the housing.

[0012] The beneficial effect of the magnetic rod filter for the multi-effect distillation process proposed by the present utility model is as follows: By holding the handle in the fixing structure, the vertical rod rotates outward. The rotating vertical rod drives the square plate to rotate outward. The rotating square plate drives the bent plate to rotate outward. At the same time, the square plate applies torsion to the spring, inserts the magnetic plate into the interior of the housing until the bottom of the top cover fits with the housing. Then release the handle. The spring loses the torsion and provides a resilience force, causing the square plate to rotate inward, and further causing the bent plate to rotate inward. The bent plate contacts the outer wall of the curved block to form a clamping connection, realizing the reinforcement of the top cover, changing the original form of fixing with multiple screw rods, reducing the disassembly and assembly difficulty of the magnetic rod filter, and facilitating the use of the magnetic rod filter.

[0020] The present utility model will be further described below in conjunction with the accompanying drawings:

[0021] Embodiment 1:

[0022] Please refer to Figures 1-6 : In this embodiment, a magnetic rod filter for a multi-effect distillation process includes a housing 1 and a straight pipe 6. The upper and lower sides of the housing 1 are respectively communicated with the inner side of the straight pipe 6. The upper straight pipe 6 is the water inlet pipe, and the lower straight pipe 6 is the water outlet pipe. A top cover 7 is provided on the front surface of the housing 1. Fixed structures 2 are respectively connected to the left and right sides of the top cover 7. A control structure 3 is connected to the inner wall of the top cover 7. Curved blocks 4 are respectively fixedly connected to the front ends of the left and right sides of the housing 1, and bottom plates 5 are respectively fixedly connected to the rear ends of the left and right sides of the housing 1.

[0023] The fixed structure 2 includes a concave plate 201 and a vertical rod 202. The inner sides of the two concave plates 201 are respectively fixedly connected to the left and right sides of the top cover 7. The upper and lower sides of the concave plate 201 are respectively rotatably connected to the outer wall of the vertical rod 202. The vertical rod 202 rotates through the bearings on the upper and lower sides of the concave plate 201 under force. A square plate 203 is fixedly connected to the inner side of the vertical rod 202. A spring 204 is sleeved on the outer wall of the vertical rod 202. The upper and lower sides of the spring 204 are respectively fixedly connected to the inner wall of the concave plate 201 and the outer wall of the square plate 203. The square plate 203 rotates outward under force and then rotates back under the elastic force of the spring 204. A handle 205 is fixedly connected to the outer side of the vertical rod 202. The handle 205 facilitates driving the vertical rod 202 to rotate. A bent plate 206 is fixedly connected to the rear end surface of the square plate 203. The inner side of the bent plate 206 is clamped with the outer wall of the curved block 4;

[0024] By holding the handle 205 in the fixed structure 2 to rotate the vertical rod 202 outward, the rotating vertical rod 202 drives the square plate 203 to rotate outward, and the rotating square plate 203 drives the bent plate 206 to rotate outward. At the same time, the square plate 203 applies torsion to the spring 204. Insert the magnetic plate 301 into the interior of the housing 1 until the bottom of the top cover 7 fits with the housing 1. Then release the handle 205. The spring 204 loses the torsion and provides a return elastic force, causing the square plate 203 to rotate inward, and further causing the bent plate 206 to rotate inward. The bent plate 206 contacts the outer wall of the curved block 4 to form a clamp, realizing the reinforcement of the top cover 7, changing the original form of multiple screw fixings, reducing the disassembly and assembly difficulty of the magnetic rod filter, and facilitating the use of the magnetic rod filter.

[0025] The control structure 3 includes a magnetic rod 301 and a screw 302. The front of the outer wall of the magnetic rod 301 is inserted into the inner wall of the top cover 7. The magnetism of the magnetic rod 301 attracts the magnetic impurities in the liquid to be filtered with opposite polarity. The inner wall of the magnetic rod 301 is threadedly connected to the outer wall of the screw 302. A cross plate 303 is fixedly connected to the front of the screw 302. The cross plate 303 facilitates driving the screw 302 to rotate. The rear of the outer wall of the magnetic rod 301 is inserted into the inner wall of the housing 1.

[0026] Working principle:

[0027] Magnetic bar filter assembly:

[0028] First, make the rear of the outer shell 1 and the bottom plate 5 fit with the connecting surface. Then, bolts pass through the bottom plate 5 from top to bottom and are fixed to the connecting surface. Next, insert the front ends of the outer walls of multiple magnetic bars 301 into the circular openings on the outer wall of the top cover 7. Then, cooperate with the cross plate 303 to gradually screw the screw rod 302 into the inner wall of the magnetic bar 301 until the rear of the cross plate 303 fits with the front of the top cover 7, completing the fixation of the magnetic bar 301. Then, hold the handle 205 and turn the vertical rod 202 outward. The rotating vertical rod 202 drives the square plate 203 to rotate outward. The rotating square plate 203 drives the bent plate 206 to rotate outward. At the same time, the square plate 203 applies torsion to the spring 204, inserts the magnetic plate 301 into the interior of the outer shell 1 until the bottom of the top cover 7 fits with the outer shell 1. Then, release the handle 205. The spring 204 loses torsion and provides resilience, causing the square plate 203 to rotate inward, and further causing the bent plate 206 to rotate inward. The bent plate 206 contacts the outer wall of the curved block 4 to form a snap connection, realizing the reinforcement of the top cover 7.

[0029] When the magnetic bar filter for multi-effect distillation process is in use:

[0030] Connect the upper straight pipe 6 to the water inlet, and connect the lower straight pipe 6 to the water inlet of the multi-effect distillation equipment. When the water source is sent into the outer shell 1 through the upper straight pipe 6, the magnetic bars 301 attract each other due to the performance of their own magnets, adsorb the magnetic impurities in the water, complete the filtration of the water source, and then discharge it into the multi-effect distillation equipment through the lower straight pipe 6. If other impurities in the water need to be filtered, when the top cover 7 and the outer shell 1 are closed, an annular filter screen can be placed on the inner wall of the outer shell 1, so as to realize the filtration of other impurities in the water.

[0031] Embodiment 2:

[0032] Please refer to Figures 1-6 : In this embodiment, a magnetic bar filter for multi-effect distillation process further includes a straight rod 8 and a circular ring 9. The inner sides of the two straight rods 8 are respectively fixedly connected to the upper and lower sides of the top cover 7, and the inner sides of the two circular rings 9 are respectively fixedly connected to the front ends of the upper and lower sides of the outer shell 1.

[0033] Working principle:

[0034] After the top cover 7 and the outer shell 1 are closed, the rear of the outer wall of the straight rod 8 will be inserted into the inner wall of the circular ring 9. The straight rod 8 and the circular ring 9 play a limiting role on the top cover 7, which can prevent the top cover 7 from rotating on the top of the outer shell 1.

[0035] Although the present utility model has been illustrated and described by referring to the preferred embodiments, those skilled in the art should understand that various changes in form and details can be made within the scope of the claims.
