Description

Technical Field

[0001] This utility model relates to the field of filter technology, specifically to a heat-insulating jacketed filter. Background Technology

[0002] Currently, insulated jacket filters are mainly used to protect the pump suction head, preventing larger particles from entering the pump. At high speeds, these particles can cause severe damage to the pump body. However, existing insulated jacket filters often become clogged during use due to excessive impurities adsorbed into the filter screen. Because these filters lack the ability to detect and alert operators when the filter screen is clogged, the filter efficiency drops significantly, allowing larger particles to pass through and enter the pump. This increases the risk of pump wear and damage, especially at high speeds. Furthermore, the lack of clogging detection and alerts makes it difficult for operators to accurately determine when to clean or replace the filter, leading to unnecessary maintenance delays or frequent downtime, impacting equipment operating efficiency and production capacity.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-6 This utility model provides a technical solution: a heat-insulating jacketed filter, including a cylindrical body 1. A filter inlet 2 and a heating outlet 3 are respectively opened from top to bottom on the front of the cylindrical body 1. A filter outlet 4 is opened on the left side surface of the cylindrical body 1. A threaded plug 15 is threadedly connected to the lower discharge port of the cylindrical body 1. A heating inlet 5 is opened on the right side surface of the cylindrical body 1. A cover plate 6 is fixedly installed on the upper surface of the cylindrical body 1 by bolts. A thermometer mounting port 7 and an exhaust port 8 are respectively opened from front to back on the upper surface of the cover plate 6. A first flow sensor 9 is fixedly installed at the inlet of the filter inlet 2, and a second flow sensor 10 is fixedly installed at the outlet of the filter outlet 4. A filter barrel 11 is fixedly installed on the inner wall of the cylindrical body 1. The outlets of the filter inlet 2 and the heating inlet 5 are both through and extend... The filter barrel 11 is connected to the inner wall of the filter barrel 11 by a connector. The filter screen 12 is slidably inserted into the inner wall of the filter barrel 11. The upper surface of the filter screen 12 is elliptical in shape when viewed along the left side length direction and slopes downward from back to front. The connector includes a slot 14 opened on the upper surface of the inner wall of the filter barrel 11. The lower surface of the filter screen 12 is slidably inserted into the inner wall of the slot 14. The filter screen 12 is provided with a cleaning component for cleaning the filter holes of the filter screen 12. The cleaning component includes cleaning blades 13 and a connecting shaft 131. Multiple cleaning blades 13 are linearly arrayed on the surface of the connecting shaft 131 along the length direction of the connecting shaft 131. The upper surface of the cover plate 6 is fixedly installed with a controller 16 for controlling the first flow sensor 9, the second flow sensor 10 and the cleaning component.

[0020] The cleaning assembly also includes a drive motor 132 embedded in the upper surface of the cover plate 6. The output shaft of the drive motor 132 is fixedly mounted with a first gear 133 via a coupling. The connecting shaft 131 is rotatably sleeved on the upper surface of the cover plate 6 via a bearing. The outer surface of the top end of the connecting shaft 131 above the cover plate 6 is keyed with a second gear 134. The outer surface of the first gear 133 meshes with the outer surface of the second gear 134. Heating channels 135 are provided inside both the connecting shaft 131 and the cleaning blades 13. The top wall of the heating channel 135 inside the connecting shaft 131 communicates with the upper surface of the connecting shaft 131. Cleaning brushes 136 arranged in a ring array are fixedly mounted on the outer end of the cleaning blades 13. In order to further enhance the cleaning effect on the filter holes of the filter screen 12, the cleaning brushes 136 of this application can also be designed as long strips when viewed along the height direction of the cylinder 1, and the upper and lower adjacent cleaning brushes 136 do not contact each other to avoid the cleaning blades from breaking. The outer surface of the cleaning brushes 136 contacts the filter holes of the filter screen 12.

[0021] With the above technical solution, when the filter screen 12 begins to clog, the pump's suction flow rate usually decreases due to increased flow resistance. By detecting and comparing the difference between the inflow and outflow rates and comparing the difference value with a preset difference threshold, potential filter screen 12 clogging problems can be identified. After the filter screen 12 is identified as clogged, the controller 16 controls the drive motor 132 to start. The drive motor 132, through the meshing of the first gear 133 and the second gear 134, drives the connecting shaft 131 and the cleaning blade 13 to rotate around the axis of the connecting shaft 131, driving the cleaning brush 136 to clean the filter holes of the filter screen 12. If the difference between the inflow and outflow rates after cleaning is still greater than the preset difference threshold, the alarm light of the controller 16 will sound to remind the staff to replace or maintain the filter screen 12 in time. The heating channel 135 is set to assist the liquid in heating and keeping it warm during filtration.

[0022] By setting up a cleaning component, the controller 16 can control the start of the drive motor 132 and the cleaning component after the controller 16 detects that the difference between the first flow sensor 9 and the second flow sensor 10 is greater than a preset difference threshold, thus ensuring the automatic cleaning of the filter screen 12. The cleaning blades 13 effectively remove the deposits on the filter screen 12 and restore its normal filtration efficiency through rotation and brushing.

[0023] Working principle: During use, the first flow sensor 9 and the second flow sensor 10, located at the filter inlet 2 and filter outlet 4 respectively, monitor the flow rate of liquid flowing into the cylinder 1 through the filter inlet 2 and out of the cylinder 1 through the filter outlet 4 in real time or periodically. The monitoring signals are fed back to the controller 16, which processes the signals to determine whether the filter needs cleaning or replacement based on flow rate changes. Specifically:

[0024] When the filter screen 12 begins to clog, the pump's suction flow rate usually decreases due to increased flow resistance. By detecting and comparing the difference between the inflow and outflow rates and comparing the difference value with a preset difference threshold, a potential filter screen 12 clogging problem can be identified. After the filter screen 12 is identified as clogged, the controller 16 controls the drive motor 132 to start. The drive motor 132, through the meshing of the first gear 133 and the second gear 134, drives the connecting shaft 131 and the cleaning blade 13 to rotate around the axis of the connecting shaft 131, thereby driving the cleaning brush 136 to clean the filter holes of the filter screen 12. If the difference between the inflow and outflow rates after cleaning is still greater than the preset difference threshold, the alarm light of the controller 16 will sound to remind the staff to replace or maintain the filter screen 12 in time. The heating channel 135 is set to assist the liquid in heating and keeping it warm during filtration.

[0025] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
