Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of plastic product extrusion processing equipment, in particular to a cooling device for a main engine of a pipe extruder. Background Art
[0002] At present, the main engine water jacket cooling of traditional extruders is directly cooled by external water source entering the water jacket. However, due to the hard water quality or impurities in the external water source, long-term cooling operation will cause blockage of the flow channel in the water jacket. The blocked water jacket cannot perform effective cooling operation, resulting in unstable main engine feeding, thereby causing waste of production products. Utility Model Content
[0003] The utility model aims to provide a cooling device for a mainframe of a pipe extruder with the function of softening and filtering cooling water.
[0004] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a cooling device for a main engine of a pipe extruder, comprising: a water jacket, a filter, a water pressure sensor and a control system, the water inlet end of the filter is connected to an external cooling pool, the water outlet end of the filter is connected to the water inlet end of the water pressure sensor, the water outlet end of the water pressure sensor is connected to the water inlet end of the water jacket, the water outlet end of the water jacket is connected to the external cooling pool, the water pressure sensor is connected to the control system, and the control system can read the low water pressure abnormal signal collected by the water pressure sensor and generate a warning prompt.
[0005] By adopting the above technical solution, the cooling water is softened and filtered by the filter before entering the water jacket to prevent impurities in the cooling water from scaling or clogging the water jacket. The water pressure sensor downstream of the filter is used to detect the status of the filter. After the filter has been filtering for a long time, the filtering structure in the filter will be blocked, causing the water pressure flowing through the water pressure sensor to be abnormally reduced. At this time, sufficient cooling water cannot be provided to the water jacket, which in turn leads to reduced cooling efficiency. At this time, the low water pressure abnormal signal collected by the water pressure sensor is input into the control system, and the control system will issue a warning to prompt the operator to clean the filter in time.
[0006] The beneficial effects of the utility model are as follows: a filter is installed in the cooling device, which can soften and filter the cooling water, ensuring that the water jacket is not blocked during a long-term cooling operation, and can effectively cool the main engine for a long time, thereby ensuring stable feeding of the main engine, improving production efficiency, and improving product quality. In addition, the cost of the filter in the later maintenance and repair costs is much lower than that of the water jacket, thereby reducing the production cost of the product.
[0007] In some embodiments, a drain valve is further included, the filter includes a sedimentation tank, the water inlet end of the drain valve is connected to the sedimentation tank, and the drain valve is used to discharge impurities filtered out by the filter.
[0008] By adopting the above technical solution, impurities in the sedimentation bin are removed through the drain valve, and then the filter is unblocked, so that the cooling water pressure required by the water jacket can be quickly restored to ensure the cooling efficiency of the water jacket.
[0009] In some embodiments, an angle seat valve is provided between the water outlet of the water jacket and the cooling pool, and the angle seat valve is controlled by the control system.
[0010] In some embodiments, the water jacket includes a temperature sensor, the angle seat valve is a single-acting normally closed type, the temperature sensor is connected to the control system, and the control system can read the high water temperature abnormal signal collected by the temperature sensor and control the on and off of the angle seat valve.
[0011] The above technical solution is adopted to avoid waste of resources and actively respond to the policy of energy conservation and emission reduction. The cooling water in the water jacket needs to reach a certain temperature before it can be discharged, so an angle seat valve and a temperature sensor are set. The angle seat valve selects a single-acting normally closed specification. The temperature sensor detects and collects the cooling water temperature inside the water jacket in real time and transmits it to the control system. When the water temperature changes within the set temperature range, the angle seat valve is in a closed state and the cooling water cannot flow out of the water jacket. When the control system finds that the cooling water temperature is too high, it will turn on the angle seat valve, and the cooling water will flow out of the water jacket through the angle seat valve.
[0012] In some embodiments, a water separator is further included, wherein the water separator is used to connect the water outlet of the water pressure sensor with the water inlet of the water jacket, and the water separator is also used to connect the water outlet of the angle seat valve with the external cooling pool.
[0013] By adopting the above technical solution, other equipment also needs to be cooled during production operations, such as the main engine gearbox, so other equipment can be connected in parallel by adding a water distributor, while taking into account the cooling operation of other equipment.
[0014] In some embodiments, the control system includes a low water pressure warning light, and when the water pressure sensor collects a low water pressure abnormality signal, the control system triggers the low water pressure warning light to light up.
[0015] With the above technical solution, the low water pressure abnormal signal collected by the water pressure sensor is input into the control system, and the control system will trigger the warning light to light up, prompting the operator to clean the filter in time.

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0022] The directions such as “front, back, left, right, up, and down” mentioned in the text are not absolutely limited and can be adjusted according to the actual placement position.
[0023] The following is combined with Figure 1 and Figure 2 The embodiments described below describe the present invention in detail.
[0024] In the embodiment, the cooling device of the main machine of the pipe extruder is specifically:
[0025] In the water inlet:
[0026] The water inlet end of the filter 2 is connected to the external cooling pool. Before the cooling water enters the water jacket 1, it is softened and filtered through the filter 2 with a filter hole diameter of 0.4 mm to prevent impurities in the cooling water from scaling or clogging the water jacket 1. The lower part of the filter 2 includes a sedimentation bin 21, which is used to deposit impurities in the water filtered by the filter 2. A ball valve type drain valve 4 is set at the lower end of the sedimentation bin 21.
[0027] The water outlet of the filter 2 is connected to the water inlet of the water pressure sensor 3, and the water pressure sensor 3 is connected to the control system. The water pressure sensor 3 downstream of the filter 2 is used to detect the state of the filter 2. After the filter 2 has been filtering for a long time, the filter holes and other filtering structures in the filter 2 will be blocked, resulting in an abnormal decrease in the water pressure flowing through the water pressure sensor 3. At this time, sufficient cooling water cannot be provided to the water jacket 1, which in turn leads to a decrease in cooling efficiency. At this time, the low water pressure abnormal signal collected by the water pressure sensor 3 is input into the control system. The control system reads the low water pressure abnormal signal collected by the water pressure sensor 3 and generates a warning to trigger the warning light to light up, prompting the operator to open the drain valve 4 in time to clean the filter 2, and remove the impurities accumulated in the sedimentation bin 21 through the drain valve 4, thereby being able to dredge the filter 2, quickly restore the cooling water pressure required by the water jacket 1, and ensure the cooling efficiency of the water jacket 1.
[0028] The water outlet of the water pressure sensor 3 is connected to the water inlet at the upper end of the water distributor 6. Other equipment also needs to be cooled during operation, such as the main engine gearbox. Therefore, by adding the water distributor 6, other equipment can be connected in parallel, while taking into account the cooling operation of other equipment.
[0029] The water inlet branch on the upper right side of the water distributor 6 is connected to the water inlet end of the water jacket 1. The water jacket 1 includes a temperature sensor, which is connected to the control system. The temperature sensor detects and collects the cooling water temperature inside the water jacket 1 in real time and transmits it to the control system.
[0030] In the return water:
[0031] An angle seat valve 5 controlled by the control system is installed at the water outlet of the water jacket 1 to avoid waste of resources and actively respond to the energy-saving and emission reduction policy. The cooling water in the water jacket 1 needs to reach a certain temperature before it can be discharged. The angle seat valve 5 selects a single-acting normally closed specification. The control system can read the high water temperature abnormal signal collected by the temperature sensor. When the water temperature changes within the set temperature range, the angle seat valve 5 is in a closed state, and the cooling water cannot flow out of the water jacket 1. When the control system finds that the cooling water temperature is too high, it will turn on the angle seat valve 5, and the cooling water will flow out of the water jacket 1 through the angle seat valve 5 and enter the return water branch on the lower side of the water distributor 6.
[0032] Finally, the cooling water flows from the return water end of the water distributor 6 into the external cooling pool.
[0033] It should be noted that there is no limitation on the filter hole, and it can be designed to other hole sizes according to actual needs, such as 0.1mm, 0.6mm, etc.
[0034] The utility model adds a filter 2 to the cooling device, which can soften and filter the cooling water, ensure that the water jacket 1 is not blocked during a long-term cooling operation, and can effectively cool the main engine for a long time, thereby ensuring stable feeding of the main engine, improving production efficiency, and improving product quality. In addition, the cost of the filter 2 in the later maintenance and repair cost is much lower than that of the water jacket 1, thereby reducing the production cost of the product.

Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present utility model, or directly or indirectly used in other related technical fields, should be included in the protection scope of the present utility model.
