[0028] The following describes the implementation of the present invention through specific embodiments. Those skilled in the art can readily understand the other advantages and benefits of the present invention from the contents disclosed in this specification. Obviously, the embodiments described are only a portion of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are also within the scope of protection of the present invention.

[0029] Refer to the instruction manual Figure 1 The sludge drying and granulation equipment of this embodiment includes an equipment body 1 and further includes:

[0030] The granulation mechanism 2 is arranged at the inner top of the equipment body 1 and is used to granulate the sludge.

[0031] In order to conveniently dry and transport the sludge, Figure 1-3 As shown, the equipment body 1 includes a fixed shell 101, and a discharge port 102 is opened at the bottom of the outer wall of one end of the fixed shell 101. A heating plate 103 is fixedly installed on the inner bottom of the fixed shell 101, and a conveyor belt 104 passing through the discharge port 102 is provided on the outside of the heating plate 103. A fixed rack 105 is fixedly installed on one side of the top of the fixed shell 101. The sludge processed by the granulation mechanism 2 falls to the top of the conveyor belt 104, can be dried by the heating plate 103, and then will be transported from the inside of the equipment body 1 to the outside through the conveyor belt 104.

[0032] In order to facilitate the granulation of sludge, Figure 1-2 and Figure 4 As shown, the granulation mechanism 2 includes a filter press plate 201 and a fixed frame 202. The filter press plate 201 is fixedly installed on the inner side of the fixed shell 101 and is arranged on the top of the conveyor belt 104. A pressure roller 203 movably connected to the top of the filter press plate 201 is rotatably installed on the inner side of the bottom of the fixed frame 202. A rotating shaft 204 is rotatably installed on the inner wall of one side of the top of the fixed frame 202. A servo motor 205 is provided on one side of the rotating shaft 204. A movable gear 206 engaged with the fixed rack 105 is fixedly sleeved on the outer side of the rotating shaft 204. The servo motor 205 works through the meshing action between the movable gear 206 and the fixed rack 105, so that the pressure roller 203 can move on the top surface of the filter press plate 201, thereby performing filter press granulation on the sludge.

[0033] In order to prevent the sludge filtered by the filter press plate 201 from falling into the gap between the conveyor belt 104 and the fixed housing 101, Figure 2-3As shown, a guide plate 107 is fixedly installed on one end of the inner wall of the fixed shell 101 away from the discharge port 102, the top of the guide plate 107 contacts the bottom of one end of the filter press plate 201, and the bottom of the guide plate 107 contacts the top of the conveyor belt 104. The width of the guide plate 107 is the same as the width of the inner wall of the fixed shell 101, and the width of the inner wall of the fixed shell 101 is the same as the width of the conveyor belt 104 and the filter press plate 201. The guide plate 107 can be used to drain the sludge granulated at one end of the filter press plate 201 so that it can stably fall to the top surface of the conveyor belt 104.

[0034] In order to make the pressing roller 203 move stably on the top of the filter press plate 201, Figure 2-4 As shown, a slide rail 106 is fixedly installed on the side of the top of the fixed shell 101 away from the fixed rack 105, and a slide groove 207 is provided on the bottom of the fixed frame 202 away from the movable gear 206. The outer wall of the slide rail 106 is movably connected to the inner wall of the slide groove 207. The left vertical sections of the slide rail 106 and the slide groove 207 are both set to rectangular structures. The width dimensions of the slide rail 106 and the slide groove 207 are both smaller than the thickness dimension of the inner wall of the fixed shell 101. The slide groove 207 moves along the outer wall of the slide rail 106, which can limit the movement of the fixed frame 202, so that the pressure roller 203 can move stably on the top of the filter press plate 201, so that the granulation mechanism 2 can stably granulate the sludge.

[0035] In order to provide power for the movement of the fixed frame 202, as Figure 2 and Figure 4 As shown, the top of one side outer wall of the fixing frame 202 is fixedly connected to the servo motor 205, and the servo motor 205 is connected to the rotating shaft 204 through an output shaft transmission. The fixing frame 202 can install and fix the servo motor 205. The operation of the servo motor 205 causes the rotating shaft 204 to rotate, and through the meshing action between the movable gear 206 and the fixed rack 105, the fixing frame 202 can move along the top of the fixed shell 101, thereby allowing the pressure roller 203 to move on the top of the filter press plate 201.

[0036] In order to ensure that the equipment body 1 can stably transport the granulated sludge, Figure 2-3 As shown, the width dimension of the discharge port 102 is the same as the width dimension of the inner wall of the fixed shell 101, the height dimension of the discharge port 102 is greater than the height dimension of the conveyor belt 104, the width dimension of the heating plate 103 is the same as the width dimension of the conveyor belt 104, and the height dimension of the heating plate 103 is less than the height dimension of the inner side of the conveyor belt 104. The heating plate 103 can dry the sludge that falls onto the conveyor belt 104, and then the granulated and dried sludge can be transported out through the discharge port 102 through the conveyor belt 104.

[0037] The specific implementation scenario is as follows: when the sludge is dried and granulated, the sludge is transported to the inside of the equipment body 1 so that it is on the top of the filter press plate 201. The servo motor 205 is operated to rotate the rotating shaft 204, thereby rotating the movable gear 206. Through the meshing action between the movable gear 206 and the fixed rack 105, the fixed frame 202 can move along the top opening of the fixed shell 101, thereby allowing the pressure roller 203 to move on the top of the filter press plate 201, thereby filtering the sludge, allowing it to pass through the holes on the inner wall of the filter press plate 201 to form particles and fall to the top of the conveyor belt 104. At the same time, the guide plate 107 can be positioned on the conveyor belt 10 The sludge particles at the top of one end are drained to prevent them from falling into the gap between the conveyor belt 104 and the fixed housing 101. The top of the conveyor belt 104 can be heated by the operation of the heating plate 103, thereby drying the granulated sludge. The granulated and dried sludge can then be transported out of the fixed housing 101 through the discharge port 102 by the movement of the conveyor belt 104. The filter press plate 201 and the pressure roller 203 can be used to conveniently granulate the sludge, thereby improving the efficiency of sludge treatment. This embodiment specifically solves the problem in the prior art that the sludge cannot be quickly granulated and dried, which affects the sludge treatment efficiency.

[0038] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, such modifications or improvements, without departing from the spirit of the present invention, are within the scope of protection claimed herein.
