Description

Technical Field

[0001] The invention belongs to the technical field of low-temperature evaporators, in particular to a low-temperature evaporator. Background Art

[0002] Low-temperature evaporator is a kind of equipment used to treat industrial wastewater and reduce emissions. Its operating temperature is lower than 70°C, and according to the different operating pressures, it can be divided into low-temperature negative pressure evaporation and low-temperature normal pressure evaporation. The working principle of the low-temperature evaporator is to use a vacuum pump to lower the evaporation chamber to below normal pressure, and at the same time heat the solution to evaporate the water in it.

[0003] In the low-temperature evaporator of the prior art, during use, as the hot steam is discharged outward, part of the solute is mixed in the steam and discharged together, and is cooled in the condensation box. However, during the cooling process, part of the solute is mixed in the condensed water. Although a conventional filtering mechanism is set up, a certain amount of solute still exists in the condensed water after the discharge and separation. The actually obtained separated liquid water is also accompanied by a large amount of solute, which greatly reduces the quality after separation, and usually requires secondary separation and purification, which increases the operation and processing steps, resulting in low comprehensive separation efficiency, poor effect, and poor use effect.

[0018] 1. The present invention utilizes a power component, a rotating filter part and a fixed extrusion part, and cooperates with a condensation component to realize the condensation of hot steam, and then utilizes the rotating filter part to absorb the condensed water. After storing the condensed water, it is squeezed with the extrusion strips in the fixed extrusion part through a rotating action, and the absorbed and stored condensed water is squeezed downward by utilizing the squeezing effect on the sponge ring, so that the solute is filtered and retained in the sponge ring, and the purified condensed water is separated.

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] like Figures 1 to 10 As shown, an embodiment of the present invention provides a low-temperature evaporator, including an assembly box 1, an evaporating cylinder 2, a circulating heating component 3, a condensing box 4 and a ventilation pipe 5. The interior of the condensing box 4 is fixedly sleeved with a fixed extruding portion 9, and a condensing component 7 located inside the fixed extruding portion 9 is fixedly provided in the condensing box 4. A rotating filter portion 8 located outside the fixed extruding portion 9 is rotatably provided inside the condensing box 4. A power component 6 is provided at the bottom of the condensing box 4. The power component 6 drives the rotating filter portion 8 to rotate. The ventilation pipe 5 is fixedly connected between the evaporating cylinder 2 and the condensing box 4. The fixed extruding portion 9 is fixedly provided in the condensing box 4. The extrusion part 9 includes: a fixed cylinder 91 fixedly sleeved in the condensation box 4, a water hole 92 opened at the bottom of the fixed cylinder 91, an extrusion strip 93 fixedly connected to the bottom of the fixed cylinder 91 and a top opening 94 opened at the top of the fixed cylinder 91, and the rotary filtering part 8 includes: a rotating cylinder 81 rotatably sleeved in the condensation box 4, a sponge ring 82 fixedly sleeved inside the rotating cylinder 81, a water leakage groove 83 surrounding the outer surface of the rotating cylinder 81, a positioning ring 84 fixedly sleeved on the outer surface of the rotating cylinder 81 and an electromagnet 85 fixedly nested on the outer surface of the rotating cylinder 81.

[0034] Embodiment 1: When in use, as the circulating heating component 3 inputs the hot steam generated by internal heating into the evaporating coil 31, the water in the mixed water flow that enters the evaporating tube 2 and is sprayed onto the evaporating coil 31 evaporates to form hot steam, and carries the solute ventilation pipe 5 to be input into the condensing box 4, and at the same time, the external cooling water is input into the condensing component 7, and the cooling water is input into the cooling plate 71 along one end and discharged from the other end. The hot steam entering the condensing box 4 condenses into liquid droplets on the surface of the cooling plate 71 and drips downward. The condensate gathered at the bottom of the inner cavity of the fixed tube 91 penetrates into the sponge ring 82 of the rotating filter part 8 through the water hole 92 and is absorbed by the sponge ring 82. The power component 6 is started, and the power motor 61 drives the meshing gear 2 63 to rotate through the gear 1 62, thereby driving the rotating tube 81 to rotate, so that the rotating tube 81 drives the sponge ring 82 to rotate. As the sponge ring 82 rotates and contacts and squeezes the extrusion bar 93, the sponge ring 82 that sucks in the condensed water is compressed and the internal condensed water is squeezed out and discharged through the leakage The water tank 83 leaks to the liquid outlet 42 and is discharged through the liquid outlet 43, while the solute is filtered and retained on the top of the sponge ring 82, completing the filtering and purification of the condensed water; as the power component 6 drives the rotation of the rotary filter part 8, the condensed water is repeatedly squeezed out, and the electromagnet 85 is started. As the rotating cylinder 81 drives the electromagnet 85 to rotate to the top, the electromagnet 85 approaches the top of the cleaning component 10 and directly magnetically attracts the magnetic metal plate 105 below through the top opening 94. Under the magnetic attraction, the magnetic metal plate 105 moves upward and drives the movable plate 101 to move upward. While compressing the spring 102, the connecting rod 103 and the cleaning rod 104 are driven to move upward synchronously. As the cleaning rod 104 moves upward, it slides along the side of the cooling plate 71 to avoid cleaning and accelerate the falling of the gathered water droplets. When the electromagnet 85 is rotated out from the top, the magnetic metal plate 105 loses its magnetic attraction, the spring 102 is elastically reset, and drives the cleaning component 10 to reset, and the cleaning rod 104 moves down again for friction cleaning to complete the up and down vibration cleaning.

[0035] Firstly, by utilizing the power component 6, the rotating filter part 8 and the fixed extrusion part 9, and cooperating with the condensation component 7 to realize the condensation of the hot steam, the rotating filter part 8 is used to absorb the condensed water. After the condensed water is stored, it is squeezed with the extrusion strips 93 in the fixed extrusion part 9 through the rotation action, and the squeeze effect on the sponge ring 82 is utilized to squeeze the absorbed and stored condensed water downward, so that the solute is filtered and retained in the sponge ring 82, and the purified condensed water is separated. Actually, for the low-temperature evaporator, after steam is generated and condensed water is obtained, the solute treatment in the condensed water is quickly realized, and the actual solute separation efficiency is high and the effect is good. The separated liquid water has high purity and cleanliness, and the evaporation separation effect is good.

[0036] In addition, through the rotation effect of the power component 6, in conjunction with the electromagnet 85 carried in the rotating filter part 8, magnetism is generated when power is turned on, and when it rotates to the upper side, it is magnetically attracted to the cleaning component 10 added above the condensation component 7, and the cleaning component 10 is driven to move upward by the magnetic attraction. After the electromagnet 85 rotates away, the cleaning component 10 elastically resets after losing the magnetic attraction, realizing an up and down action, and in conjunction with the reciprocating rotation of the electromagnet 85, the reciprocating vibration of the cleaning component 10 is realized, thereby forming an up and down vibration between the gaps of the cooling plate 71 of the condensation component 7, and the contacting cleaning rod 104 is used to frictionally clean the outer side of the cooling plate 71 to reduce dirt attached to the surface and at the same time increase the dripping speed to avoid the gathering of water droplets, thereby realizing the synchronous self-cleaning of the condensation component 7 and increasing the speed of the condensed water gathering and dripping, thereby improving the separation efficiency of the liquid water of the low-temperature evaporator.

[0037] Embodiment 2: When low-temperature evaporation is performed, as the power assembly 6 drives the rotating filter part 8 to rotate, squeeze and filter, the output shaft of the power motor 61 drives the connected connecting shaft 115 to rotate, and drives the blades 114 in the air outlet tube 113 to be selected, generating axial flow wind, and the air volume is input into the heat dissipation box 111 through the curved pipe 112, and acts on the outer surface of the ventilation pipe 5 to accelerate the condensation of internal hot steam.

[0038] First, by utilizing the rotation control of the power component 6 again, while realizing the rotation extrusion of the rotary filter part 8 to obtain purified water, it also drives the rotation of the blades 114 in the air supply component 11, cooperates with the air outlet pipe 113 to form axial flow air volume, and cooperates with the curved pipe 112 to guide the flowing airflow to the heat sink 111, and cooperates with the heat sink 111 installed on the outside of the ventilation pipe 5 to realize the input of internal flowing gas, form convection heat exchange on the outer surface of the ventilation pipe 5, increase the cooling and condensation speed of the internal hot steam, further improve the condensation purification and separation efficiency of the hot steam obtained by low-temperature evaporation, and have a good use effect.

One end of the box body 41 is communicated with the ventilation pipe 5, and the ventilation pipe 5 inputs steam into the interior of the fixed extrusion part 9.

[0042] Hot steam is introduced into the condensation box 4 to cooperate with the internal condensation component 7 to complete the condensation process. The liquid outlet 42 cooperates with the liquid outlet part 43 to realize the discharge of the condensed water after separation. The annular groove cooperates with the positioning ring 84 to maintain the rotation stability of the rotating filter part 8.

The water holes 92 are evenly spaced and distributed in an arc shape at the bottom of the fixed tube 91 .

[0049] Among them, a cleaning component 10 is provided on the top of the condensation component 7, and the cleaning component 10 includes a movable plate 101, a spring 102, a connecting rod 103, a cleaning rod 104 and a magnetic metal plate 105.

[0050] The cleaning component 10 is arranged above the condensation component 7, and the cleaning rod 104 array is distributed in the gap of the cooling plate 71. Under the magnetic attraction of the rotating filter part 8, the cleaning component 10 is moved upward and reset downward after losing the magnetic attraction, and the up and down vibration friction is realized in the gap between the cooling plates 71 to complete the surface cleaning and accelerate the dripping of the gathered water droplets, thereby ensuring the heat exchange efficiency and increasing the speed of condensation dripping. The spring 102 is used for elastic reset, and the magnetic metal plate 105 moves upward when sensing the magnetic force above.

[0051] Among them, the air supply component 11 includes a heat sink 111, a curved pipe 112, an air outlet cylinder 113, blades 114 and a connecting shaft 115.

[0053] The working principle and use process of the present invention are as follows: when in use, as the circulating heating component 3 inputs the hot steam generated by internal heating into the evaporating coil 31, the water in the mixed water flow that enters the evaporating tube 2 and is sprayed onto the evaporating coil 31 evaporates to form hot steam, and carries the solute through the ventilation pipe 5 and inputs it into the condensing box 4. At the same time, the external cooling water is input into the condensing component 7, and the cooling water is input into the cooling plate 71 along one end and discharged from the other end. The hot steam that enters the condensing box 4 condenses into liquid droplets on the surface of the cooling plate 71 and drips downward. The condensate gathered at the bottom of the inner cavity of the fixed tube 91 passes through the water holes. 92 penetrates into the sponge ring 82 of the rotating filter part 8 and is absorbed by the sponge ring 82, the power assembly 6 is started, the power motor 61 drives the meshing gear 2 63 to rotate through the gear 1 62, thereby driving the rotating cylinder 81 to rotate, so that the rotating cylinder 81 drives the sponge ring 82 to rotate, and as the sponge ring 82 rotates and contacts and squeezes with the squeezing strip 93, the sponge ring 82 that absorbs the condensed water is compressed and the internal condensed water is squeezed out, and leaks to the liquid outlet 42 through the leakage groove 83, and is discharged through the liquid outlet 43, while the solute filtration is retained on the top of the sponge ring 82, completing the filtration and purification of the condensed water; as the power Component 6 drives the rotation of the rotary filter part 8 to complete the repeated extrusion of condensed water and start the electromagnet 85. As the rotating cylinder 81 drives the electromagnet 85 to rotate to the top, the electromagnet 85 approaches the top of the cleaning component 10 and directly magnetically attracts the magnetic metal plate 105 below through the top opening 94. Under the magnetic attraction, the magnetic metal plate 105 moves upward and drives the movable plate 101 to move upward. While compressing the spring 102, it drives the connecting rod 103 and the cleaning rod 104 to move upward synchronously. As the cleaning rod 104 moves upward, it slides along the side of the cooling plate 71 to avoid cleaning and accelerate the falling of the gathered water droplets. When the electromagnet 85 is rotated out from the top, the magnetic metal plate 105 loses its magnetic attraction, the spring 102 elastically resets, and drives the cleaning component 10 to reset, and the cleaning rod 104 moves down again for friction cleaning to complete the up and down vibration cleaning; when low-temperature evaporation is performed, as the power component 6 drives the rotating filter part 8 to rotate and squeeze and filter, the output shaft of the power motor 61 drives the connected connecting shaft 115 to rotate, and drives the blades 114 in the air outlet cylinder 113 to select, generating axial flow wind, and the air volume is input into the heat dissipation box 111 through the curved pipe 112, and acts on the outer surface of the ventilation pipe 5 to accelerate the condensation of internal hot steam.
