Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of sewage treatment, and in particular relates to a filter belt deviation correction detection and protection system in a belt-type concentrating filter press integrated machine in a sewage treatment plant. Background Art
[0002] During the operation of the belt-type concentrated filter press, the filter belt often deviates due to uneven tension, so a filter belt deviation device is required to correct the deviation of the filter belt. The deviation detection and deviation protection devices of the belt-type concentrated filter press commonly used at present have the following problems: the deviation detection device and the deviation protection device are two mechanisms, and separating them from each other not only takes up space, but also increases the failure points and costs. Secondly, the traditional deviation detection device uses a pneumatic button for pneumatic control, while the deviation protection device is electrically controlled. The two are independent of each other, and the control connection and consistency are poor. Summary of the invention
[0003] The invention provides a filter belt deviation correction detection and protection system, so as to provide a system with simple and compact structure and capable of continuously controlling the deviation correction function.
[0004] The technical solution of the utility model is as follows: A filter belt deviation correction detection and protection system, comprising: a first bracket, a follower rod, a detection rod, a detection sensor, a protection sensor and a second bracket, the detection rod and the follower rod are connected at an angle, the connection point between the follower rod and the detection rod is fixed on the first bracket, the follower rod and the detection rod can rotate around the connection point, the detection sensor and the protection sensor are installed on the first bracket, when the follower rod is in a vertical state, the detection rod faces the detection sensor, and when the follower rod is at the maximum inclination angle, the detection rod faces the protection sensor.
[0005] Furthermore, a roller is sleeved on the bottom of the follower rod.
[0006] Furthermore, one end of the first bracket facing away from the detection rod and the follower rod is connected to the top of the first bracket.
[0007] Furthermore, the length of the follower rod is greater than the length of the detection rod.
[0008] Furthermore, the detection sensor and the protection sensor are both photoelectric sensors.
[0009] Beneficial effects of the utility model: the utility model installs the detection sensor and the protection sensor in the same set of follow-up devices, and the follow-up rod rotates to different angles to trigger different sensors, so as to realize the deviation detection and deviation protection functions of the belt-type concentrating filter press. BRIEF DESCRIPTION OF THE DRAWINGS
[0010] Figure 1 It is a schematic diagram of the deviation correction detection trigger of the utility model.
[0011] Figure 2 It is a schematic diagram of protection detection triggering of the utility model. DETAILED DESCRIPTION
[0012] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. The described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.
[0013] In an embodiment of the present utility model, Figure 1 It is a structural schematic diagram provided according to the specific structure of a filter belt deviation correction detection and protection system of the utility model, such as Figure 1 As shown, the utility model specifically includes:
[0014] The first bracket 1, the follower rod 2, the detection rod 3, the detection sensor 6, the protection sensor 7 and the second bracket 5, the detection rod 3 and the follower rod 2 are connected at an angle, the specific angle can be determined by the technician according to the actual situation, and the angle is generally less than 90°. In order to make the follower rod 2 as vertical as possible in the natural state, the length of the follower rod 2 is greater than the length of the detection rod 3. The bottom of the follower rod 2 is sleeved with a roller 8, and the roller 8 is installed along the axial direction of the follower rod 2. Thereby, rolling friction is achieved between the follower rod 2 and the filter belt, which prevents the follower rod 2 from contacting the filter belt edge for a long time and scratching the filter belt, which affects the service life of the filter belt.
[0015] The connection point 4 between the follower rod 2 and the detection rod 3 is fixed on the first bracket 1, and the connection point 4 is rotatably connected to the first bracket 1, and can be specifically a pin connection, so that the follower rod 2 and the detection rod 3 can rotate around the connection point 4.
[0016] The detection sensor 6 and the protection sensor 7 are installed on the first bracket 1. When the follower rod 2 is in a vertical state, that is, the filter belt has not deviated, the detection rod 3 faces the detection sensor 6. When the follower rod 2 is at the maximum tilt angle, that is, the filter belt deviates and reaches the maximum deviation, the detection rod 3 faces the protection sensor 7. The detection sensor 6 and the protection sensor 7 can both be photoelectric sensors.
[0017] like Figure 1 and Figure 2As shown, the specific operation mode of the utility model is as follows: the roller 8 at the bottom of the follower rod 2 contacts the filter bag. When the filter belt is in the correct position, the follower rod 2 remains in a vertical state, and the detection rod 3 shields the detection sensor 6. When the filter belt deviates, the follower rod 2 is pushed by the filter belt and tilts to the left. The detection rod 3 tilts upward and deviates. At this time, the detection rod 3 does not shield the detection sensor 6. The detection sensor 6 sends a detection signal. The controller connected to the detection sensor 6 starts the deviation correction device after receiving the detection signal. When the filter belt deviates to the maximum value, the detection rod 3 reaches the position of the protection sensor 7 under the drive of the follower rod 2, so that the protection sensor 7 detects the detection rod 3 and sends a protection signal. The controller connected to the protection sensor 7 stops the operation of the entire device according to the protection signal. The above-mentioned controller can be the main controller of the filter press or a separate PLC control, so it will not be repeated here.
[0018] Finally, it should be noted that the above specific implementation methods are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to examples, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
