Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning equipment technology, specifically to a dewatered sludge feeding hopper and a drying and dewatering device. Background Technology
[0002] In the pharmaceutical manufacturing process, the air in the workshop is often cleaned. After the wastewater is purified and undergoes sedimentation treatment, a large amount of sludge is produced. The sludge needs to be treated. After dewatering, the sludge is dried into sludge cakes, bagged, and transported to a treatment plant for final processing.
[0003] After being automatically dried by mechanized drying and dewatering equipment, sludge becomes sludge cake. To facilitate bagging, the discharge port of the sludge cake is positioned a certain distance from the ground for convenient subsequent operations. Currently, sludge cake discharge uses a hopper as the discharge port. To prevent sludge cake from clogging the port, an open hopper is often used, and the bagging process is done manually. During bag changing, discharge needs to be stopped to prevent sludge cake from falling to the ground and increasing cleaning work. A common structure for controlling hopper discharge is a switch at the hopper discharge port. However, in actual sludge bagging, sludge cakes collide and break apart during discharge, producing some residue. Therefore, when receiving the sludge, the bag needs to be placed over the hopper discharge port. Operating the discharge port switch is inconvenient and allows residue to easily be carried away and fall to the ground. Other related technologies that use a discharge switch within the hopper require a transmission structure and drive source, making the structure relatively complex, difficult to manufacture, and relatively expensive.

[0028] In order to make the purpose, technical solutions and advantages of the present application clearer, further detailed description of the present application is made below in combination with embodiments and drawings, the illustrative embodiments of the present application and the description thereof are only used to explain the present application, and do not limit the present application.
[0029] As shown in Figures 1-3 the first aspect, the embodiments of the present application provide a dewatered sludge feeding hopper, which comprises a hopper body 1, a blocking plate 2 and a limiting body 3; an avoiding hole is formed in the side wall of the hopper body 1; one end of the blocking plate 2 is located outside the hopper body 1, and the other end of the blocking plate 2 passes through the avoiding hole and is located inside the hopper body 1; the limiting body 3 is located inside the hopper body 1 and is connected with the blocking plate 2, and the limiting body 3 can move towards the avoiding hole together with the blocking plate 2 to form a rotating fit with the hopper body 1.
[0030] In the embodiments of the present application, the hopper body 1 is composed of two square frames and a quadrangular prism frame, the cross-sectional shape of the quadrangular prism is a right trapezoid, and the two ends of the quadrangular prism frame are connected with the two square frames, that is, one of the square frames is larger than the other, one end of the larger square frame is used as the feeding port of the hopper body 1, and one end of the smaller square frame is used as the discharging port of the hopper body 1, wherein the frame edge of the larger square frame is used to connect the sludge treatment equipment, so that the treated sludge is discharged from the sludge treatment equipment and collected by the workers after passing through the feeding hopper.
[0031] In the embodiments of the present application, the avoiding hole can be arranged on the side wall of the quadrangular prism frame, the quadrangular prism frame has a relatively large space, and the installation of the blocking plate 2 is facilitated; the avoiding hole can be constructed as a long hole, the length direction and the depth direction of the avoiding hole are perpendicular to the flow direction of the hopper body 1, that is, after the blocking plate 2 is located in the avoiding hole, the plate surface of the blocking plate 2 can be perpendicular to the flow direction of the hopper body 1, so that the blocking plate has a good blocking effect on the sludge cake; the avoiding hole has a certain depth, which is greater than the wall thickness of the quadrangular prism frame, and the hole wall of the avoiding hole can play a certain rotating limiting effect on the blocking plate, so as to ensure that the blocking plate has a stable blocking effect on the sludge cake, specifically, the avoiding hole is arranged on the quadrangular prism frame, and the depth direction of the avoiding hole is arranged to be perpendicular to the flow direction of the hopper body 1, that is, in the flow direction of the hopper body 1, the projections of the front and rear hole walls of the avoiding hole do not completely coincide, but are arranged in a left-right manner, and the coincidence degree / interval of the projections of the two hole walls is determined according to the slope of the side wall of the quadrangular prism frame, and in actual implementation, the interval of the projections of the two hole walls is greater than the thickness of the blocking plate 2, so that the blocking plate 2 is more easily rotated, and the arrangement of the two hole walls can play a good rotating limiting effect on the blocking plate 2, and can prevent the blocking plate 2 from being greatly rotated due to the impact of the sludge cake during the blocking process.
[0032] In the embodiments of the present application, the specific structure of the limiting body 3 can not be limited, and the rotating cooperation between the limiting body 3 and the hopper body 1 is also not particularly limited. For example, the limiting body 3 can be rotatably connected with the hopper body 1 to realize the rotating cooperation, or the limiting body 3 can be in contact with the hopper body 1 to realize the rotating cooperation. That is to say, in the embodiments of the present application, the rotating cooperation includes the case that one component can rotate on another component after the one component is in contact with the another component. For example, in some optional embodiments, after the baffle plate 2 is pulled out, the state of the baffle plate 2 does not affect the discharging of the sludge cake, that is to say, the baffle plate 2 basically does not need to be particularly limited, and therefore the limiting body 3 is configured as a U-shaped plate with a thickness smaller than that of the baffle plate 2 to form the rotating cooperation with the avoiding hole when the limiting body 3 moves towards the avoiding hole along with the baffle plate 2. That is to say, here, after the limiting body 3 is in contact with the hopper body 1, the baffle plate 2 can be hung on one side wall of the avoiding hole by the limiting body 3 when the baffle plate 2 rotates in the avoiding hole. In other embodiments, the limiting body 3 can also be configured as a shaft body with a diameter greater than the projection distance between the two hole walls.
[0033] The dehydrated sludge discharging hopper provided in the embodiments of the present application can realize the control of the discharging of the sludge cake by opening the avoiding hole on the side wall of the hopper body 1 and arranging the baffle plate 2 in the avoiding hole, and by pulling out the baffle plate 2 to block the discharging channel of the hopper. Meanwhile, after the baffle plate 2 is pulled out, the rotating cooperation between the limiting body 3 and the hopper can realize the rotation of the baffle plate 2, so as to change the posture of the baffle plate 2 and reduce the overall space occupation of the discharging hopper to a certain extent. Compared with the prior art, the structure for controlling the discharging in the dehydrated sludge discharging hopper provided in the embodiments of the present application is located between the discharging port and the feeding port of the hopper body 1, and the operator does not need to be close to the discharging port during operation, so that the operation is relatively convenient, and there is no risk of taking the residues at the discharging port away and falling to the ground. Compared with the arrangement of the automatic structure in the hopper body 1, the dehydrated sludge discharging hopper provided in the embodiments of the present application has a simpler structure, is easy to manufacture, and greatly reduces the manufacturing cost.
[0034] In some optional embodiments, one end of the baffle plate 2 is configured as a bending structure.
[0035] In the embodiments of the present application, the end of the baffle plate 2 is the end located outside the hopper body 1, and the arrangement of the bending structure can facilitate the operation of the baffle plate 2 by the worker.
[0036] Specifically, the bending structure is configured to bend towards the feeding port when the limiting body 3 moves away from the avoiding hole and is in contact with the inner wall of the hopper body 1, so that after the baffle plate 2 is pulled out, the residues existing on the baffle plate 2 move by themselves under the action of inertia. At this time, the bending structure can block the residues to reduce the probability of the residues falling to the ground, thereby facilitating the reduction of the probability of the ground environment being polluted.
[0037] In some optional embodiments, when the limiting body 3 moves towards the direction away from the avoiding hole and contacts with the inner wall of the hopper body 1, the operating gap suitable for accommodating fingers is formed between one end of the blocking plate 2 and the outer wall of the hopper body 1. In this way, the operating convenience can be further improved, and the fingers of the worker will not be clamped or interfered with the blocking plate 2 during the pushing process of the blocking plate 2, so that the worker can hold the blocking plate 2 conveniently.
[0038] In some optional embodiments, the buffering plate 4 is further arranged on the inner wall of the hopper body 1, one end of the buffering plate 4 is connected with the inner wall of the hopper body 1, and a gap is formed between the other end of the buffering plate 4 and the inner wall of the hopper body 1 to provide an elastic tendency when the other end of the buffering plate 4 approaches the inner wall of the hopper body 1, wherein the buffering plate 4 is located between the blocking plate 2 and the feeding port of the hopper body 1.
[0039] In the embodiments of the present application, the buffering plate 4 can provide a buffering space in the hopper body 1. After the blocking plate 2 blocks the sludge cake, the sludge cake will not be accumulated on the blocking plate 2, but can slowly perist in the buffering space provided by the buffering plate 4, that is, even under the blocking of the blocking plate 2, the sludge cake in the hopper body 1 still maintains a slow flow state, so that after the blocking plate 2 is pulled out, the sludge cake in the hopper body 1 can quickly enter the bag from the discharge port of the hopper body 1, that is, by arranging the buffering plate 4, the flow response speed of the material after the blocking plate 2 is pulled out can be improved, which will be conducive to improving the overall bagging efficiency of the sludge cake.
[0040] In some optional embodiments, the buffering plate 4 is configured as a spring sheet.
[0041] In some optional embodiments, the buffering plate 4 forms an included angle of 30-35 degrees with the inner wall of the hopper body 1. If the included angle between the buffering plate 4 and the hopper body 1 is too large, it will form a certain blocking effect on the sludge cake, which is not conducive to the discharge of the sludge cake, and if the included angle is too small, the sludge cake will flow slowly on the blocking plate 2 for a short time, and the worker may encounter a blocking problem during the bag changing process; when the included angle is configured to be 30-35 degrees, the discharge smoothness and the buffering effect can be considered.
[0042] In some optional embodiments, the discharge port of the hopper body 1 is provided with a hook for hanging the receiving bag. By arranging the hook, the receiving bag can be hung, which can bring convenience to the sludge cake bagging process.
[0043] On the other hand, the embodiments of the present application provide a drying and dewatering equipment, which comprises any one of the dewatered sludge discharging hoppers in the first aspect; wherein the feeding port of the dewatered sludge discharging hopper is connected to the sludge cake outlet of the drying and dewatering equipment.
